Implementation of the invention

To more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly describes the drawings illustrating these options. Those skilled in the art can apply the present invention to other similar scenarios in accordance with these drawings without much creative effort. Unless the context makes it obvious or the context illustrates otherwise, like reference numerals throughout the drawings are assigned to like structures or operations.

It should be understood that the terms "system", "device", "unit" and/or "module" as used herein serve to distinguish between different components, elements, parts or assemblies at different levels. However, if the same goal can be achieved by other words, the corresponding words can be replaced by other expressions.

As used herein and in the appended claims, the singular form "some", "some" and "this" also covers the plural, unless the context clearly dictates otherwise. In general, the terms "comprising" and "including" only suggest the steps and elements explicitly identified, and these steps and elements do not constitute an exhaustive list. The methods or apparatus may also contain other steps or elements.

Logic diagrams are used in the present description to illustrate the operations performed by the system according to some embodiments of the present invention. It should be understood that operations described as earlier or later may not necessarily be performed in exactly that order. Instead, each step may be performed in reverse order, or some steps may be performed simultaneously. At the same time, other operations may be added to the procedures, or a step or several steps may be excluded from the procedures.

The present invention provides a communication system for an acoustic input and output device. As shown in FIG. 1 and FIG. 2, in some embodiments, the communication system may include an acoustic input and output device 10, an intercom device 20, and an external communication module 30.

The acoustic input and output device 10 may be a device having an audio input function and an audio output function. In some embodiments, the acoustic input and output device 10 may be divided into a bone conduction device and an air conduction device according to the way sound is input and output. Taking a speaker module as an example, a bone conduction speaker can convert audio signals into mechanical vibrations at different frequencies. The human bone can be configured as a medium to transmit mechanical vibrations and further to transmit sound waves to the auditory nerve, so that the user can receive sound without passing it through the external auditory canal and eardrum in the user's ear. An air conduction loudspeaker can change the density of the air by "pushing" the air to vibrate it so that the user can hear the sound. Alternatively, the acoustic input and output device 10 may have a Bluetooth function. As shown in FIG. 2, the acoustic input and output device 10 may include the first Bluetooth module 101. This first Bluetooth module 101 may be configured to perform a Bluetooth communication function.

The intercom device 20, i. e. the portable radio may be a terminal device for cluster communication or a radio communication device for mobile communication. In general, a portable radio can convert an electrical signal corresponding to audio signals into a high frequency carrier signal via its transmitter. This high frequency carrier signal may be further, after amplification, filtering or other similar processing, transmitted through an antenna to transmit the user's voice. The antenna may receive an input signal processed through an appropriate conversion, filtering, amplification, mixing, or other similar operation, to generate an audio signal that can be reproduced by the loudspeaker module, so that the user can hear the audio signals transmitted by other intercom devices. The intercom device 20 in this embodiment may be an existing, known intercom device, so the components and construction of this intercom device 20 will not be described in detail here.

In some embodiments, intercom device 20 may not support the Bluetooth function. In order for the acoustic input and output device 10 to have an efficient Bluetooth connection with the intercom device 20, the external communication module 30 can be used as the Bluetooth communication medium of the acoustic input and output device 10 and the intercom device 20 .

In some embodiments, the intercom device 20 may comprise a first external interface 201. The intercom device 20 may use this first external interface 201 to extend the functionality of the intercom device 20, and the addition of other external modules may implement other functions. The external terminals may provide programs to the intercom device 20 via the first external interface 201. This first external interface 201 may contain several contact points spaced at some intervals, for example 7 contact points.

In some embodiments, the external communication module 30 may include a second external interface 301 and a second Bluetooth module 302. This external communication module 30 may be installed on the intercom device 20 so that it can be removed, for example, the external communication module 30 may be fixed on the device 20 intercom by snapping. The second external interface 301 may also have the same contact points as the first external interface 201. When the external communication module 30 is installed on the intercom device 20, the first external interface 201 may be connected to the second external interface 301. The external communication module 30 may be connected to the intercom device 20 via the first external interface 201 and the second external interface 301. The intercom device 20 may be configured with a Bluetooth function via the external communication module 30 .

As shown in FIG. 2, in some embodiments, the intercom device 20 may establish a Bluetooth connection from the acoustic input and output device 10 through the external communication module 30. After establishing a Bluetooth connection between the intercom device 20 and the acoustic input and output device 10 via the external communication module 30, this acoustic input and output device 10 can be used to control the intercom device 20. For example, acoustic input and output device 10 may be used to respond to audio signals received by intercom device 20. Acoustic input and output device 10 can also be used to transmit the corresponding voice. This acoustic input and output device 10 may also control other functions of the intercom device 20 . The intercom device 20 may also control the acoustic input and output device 10 .

In some embodiments, in order to facilitate the rapid establishment of a Bluetooth connection between the acoustic input and output device 10 and the intercom device 20, Bluetooth addresses can be quickly exchanged between the acoustic input and output device 10 and the intercom device 20 to provide an accelerated pairing. . As shown in FIG. 2, the acoustic input and output device 10 may also have a near-field communication (NFC) function and may include a first NFC module 102 that can be configured to perform this near-field communication function. The external communication module 30 may also include a second NFC module 303 that may allow the intercom device 20 not having a near field communication (NFC) function to realize near field communication.

Specifically, the acoustic input and output device 10 and the intercom device 20 can exchange Bluetooth addresses via near field communication between the first NFC unit 102 and the second NFC unit 303, so that a Bluetooth connection can be established between the first Bluetooth unit 101 and the second Bluetooth unit 302. by establishing a connection in a pair of Bluetooth modules. The following methods can be used to exchange Bluetooth addresses.

First, the acoustic input and output device 10 can pass the Bluetooth address to the intercom device 20, which can save time that the intercom device 20 would otherwise spend searching for and selecting the acoustic input and output device 10. In other words, the first NFC 102 may store or obtain the Bluetooth address of the first Bluetooth 101. When the first NFC 102 and the second NFC 303 communicate in the near field, the first NFC 102 may transmit the Bluetooth address to the second NFC 303, thereby allowing communication unit 30 to obtain the Bluetooth address of the first Bluetooth unit 101. Accordingly, Bluetooth addresses can be exchanged, and fast pairing of the modules can also be performed.

The second method is that the intercom device 20 can pass the Bluetooth address to the acoustic input and output device 10, which can save time that the acoustic input and output device 10 would spend searching for and selecting the intercom device 20. In other words, the second NFC 303 may store or obtain the Bluetooth address of the second Bluetooth 302. When the first NFC 102 and the second NFC 303 communicate in the near field, the second NFC 303 may transmit the Bluetooth address of the second Bluetooth 302 to the first NFC 102 , thereby allowing the acoustic input and output device 10 to obtain the Bluetooth address of the second Bluetooth module 302. Accordingly, Bluetooth addresses can be exchanged, and the modules can also be quickly paired.

The third method: the intercom device 20 and the acoustic input and output device 10 can actively transmit Bluetooth addresses to each other, thereby saving time that would otherwise be spent by them searching and selecting one and the other, and achieving fast pairing. In other words, the first NFC unit 102 may store or obtain the Bluetooth address of the first Bluetooth unit 101, and the second NFC unit 303 may store or obtain the Bluetooth address of the second Bluetooth unit 302. When the first NFC unit 102 and the second NFC unit 303 communicate in the near field, the first NFC unit 102 and the second NFC unit 303 may exchange the Bluetooth addresses of one and the other to perform the exchange of Bluetooth addresses.

The use of the second NFC module 303 in the external communication module 30 makes it possible to quickly establish a Bluetooth connection between the intercom device 20 and the first NFC module 102 of the acoustic input and output device 10, so that the intercom device 20 can quickly establish a connection with various units of the acoustic input and output device 10. Taking a job in industry as an example, different employees may have different units of the acoustic input and output device 10 . For example, two employees can share one intercom device 20, then these two employees can use this common intercom device 20 alternately when they work in shifts, so that this intercom device 20 can be quickly connected through the corresponding acoustic input and output device 10. When one of the employees is on duty, one-touch communication can be realized through the acoustic input and output device 10 and the intercom device 20, and a communication system composed of the intercom device 20 and the acoustic input and output device 10 can be used. When this employee is not on duty and another employee is on duty, this other employee can also perform "one-touch communication" through the acoustic input and output device 10 and the intercom device 20. Such a communication system, composed of the intercom device 20 and the acoustic input and output device 10, can realize a logic circuit containing two states "independent" and "shared". "Independent" may mean that anyone can use the acoustic input and output device 10 independently, and "shared" may mean that the intercom device 20 can be shared. The communication system in this embodiment can also identify the acoustic input and output device 10 individually, and several people can use the same intercom device 20. Fast switching and other functions such as presence check and employee identification can be implemented here.

The intercom device 20 and the acoustic input and output device 10 can perform Bluetooth negotiation to quickly establish a Bluetooth connection using near-field NFC communication, so that the user's ears can be released when the user wears the acoustic input and output device 10. By transmitting sound through bone conduction, the effect of noise on sound transmission can be reduced and voice quality can be improved. With this approach, by reproducing the audio signal received by the intercom device 20 through the acoustic input and output device 10, or by receiving audio for transmission to other intercom devices through the intercom device 20 in question, by means of the acoustic input and output device 10, it is possible to avoid the wide "broadcasting" of this sound and protect the user's privacy. For application scenarios such as factory floors, when using the acoustic input and output device 10 for intercom, the user may also notice changes in the environment, which may contribute to the safety of the user.

In the acoustic input and output device 10, the first NFC module 102 may be a passive NFC module. This first NFC unit 102 may store the Bluetooth address of the first Bluetooth unit 101, and this Bluetooth address of the first Bluetooth unit 101 may be passed to the second NFC unit 303. The first NFC unit 102 may also be an active NFC unit that may transmit the Bluetooth address of the first Bluetooth unit 101 and receive the Bluetooth address of the second Bluetooth unit 302 transmitted by the second NFC unit 303. Similarly, the second NFC unit 303 may also be a passive NFC unit or an active NFC unit.

For ease of installation, the first NFC module 102 may also be attached to the battery module 14 of the acoustic input and output device 10. This design can be kept simple to save space. When a Bluetooth connection is required with the intercom device 20, a quick pairing of the Bluetooth modules can be made by placing the battery module 14 of the acoustic input and output device 10 close to the external communication module 30 of the intercom device 20.

In some embodiments, to facilitate control between the intercom device 20 and the acoustic input and output device 10 and implement automatic switching of the corresponding functions between the intercom device 20 and the acoustic input and output device 10, perception and control by an appropriate sensor can be used. An example is given in the following description. As shown in FIG. 2, the acoustic input and output device 10 may include a sensor module 17 for determining whether the user is wearing the acoustic input and output device 10. In particular, the sensor module 17 may include, for example, an optical sensor that can determine whether the user is carrying the acoustic input and output device 10 by transmitting and/or receiving an appropriate optical signal. The optical sensor may be, for example, a low beam sensor that emits a corresponding optical signal and reflects this optical signal when the user is wearing the acoustic input and output device 10, or may not reflect light when the user is not wearing the acoustic input and output device 10. The passing light sensor may determine whether the user is wearing the acoustic input and output device 10, or perform a distance measurement according to whether reflected light is received. This low beam sensor can be, for example, an infrared low beam sensor. The sensor module 17 may also include an acceleration sensor, a gravity sensor, a contact sensor, or the like.

When the acoustic input and output device 10 and the intercom device 20 are in a Bluetooth connection state and the sensor module 17 determines that the user is wearing the acoustic input and output device 10, the acoustic input and output device 10 can be controlled to receive sound and/or voice, and the intercom device 20 may not be used for sound reception and/or voice reproduction. In other words, when the user is wearing the acoustic input and output device 10, the communication system can receive sound through the microphone of the acoustic input and output device 10 and/or reproduce the voice through the loudspeaker 113. When the sensor module 17 determines that the user is not wearing the acoustic input and output device 10 and output on itself, the intercom device 20 may be controlled to receive sound and/or reproduce voice, and the acoustic input and output device 10 may not be used to receive sound and/or reproduce voice. In other words, when no one is wearing the acoustic input and output device 10, the communication system can receive sound through the microphone of the intercom device 20 and/or play voice through the speaker 113.

Based on the above description, when no one is wearing the acoustic input and output device 10, the acoustic input and output device 10 may not be able to receive sound or reproduce voice effectively, or the user may not hear the voice transmitted by the acoustic input and output device 10. At this time, the intercom device 20 can be used to receive sound and/or voice, so that the voice being played can be heard clearly and the sound can be received effectively. When the user wears the acoustic input and output device 10, the acoustic input and output device 10 can be used to receive sound and/or reproduce the voice so that the user can transmit or hear the voice. Determining whether the user is wearing the acoustic input and output device 10 by means of the sensor module 17 may be convenient for communication systems to realize automatic switching as described and avoid loss of voice information, which can be adapted to various application scenarios and improve operation efficiency.

On FIG. 3 is a plan view illustrating the general construction of an acoustic input and output device in accordance with some embodiments of the present invention. As shown in FIG. 3, in some embodiments, the acoustic input and output device 10 may include speaker modules 11, a sound receiver module 16, and a connector assembly 18. The speaker modules 11 may be configured to generate an audio signal, the sound receiver module 16 may be configured to receive an audio signal, and the connector the node 18 may be configured to connect the loudspeaker modules 11 and the sound receiving module 16 to transmit an audio signal.

The speaker modules 11 can be configured to convert a signal containing audio information into an acoustic signal (or into a voice signal). For example, the speaker modules 11 may generate mechanical vibrations to transmit sound waves (eg, sound signals) in response to receiving a signal containing sound information. In some embodiments, the implementation of the loudspeaker modules may contain oscillatory elements and/or elements for transmitting vibrations connected to the oscillatory elements (for example, at least part of the housing part for transmitting vibrations in the acoustic input and output device 10). The speaker modules 11 can generate mechanical vibrations using power conversion, so that the speaker modules 11 can convert a signal containing audio information into mechanical vibrations. Such a transformation can cover many different types of coexistence and transformation of different types of energy. For example, an electrical signal (ie, a signal containing sound information) can be directly converted into mechanical vibrations by means of transducers (not shown in the drawing) in oscillatory elements (not shown in the drawing) in the loudspeaker modules 11. The sound waves can be transmitted by means of mechanical vibration transmission elements for vibration transmission in the loudspeaker modules 11 . As another example, audio information may be embedded in an optical signal, and a specific transducer may implement the process of converting the optical signal into a mechanical vibration signal. Other types of energy that can coexist and be converted during the operation of the converters may include thermal energy, magnetic field energy, or some other form of energy. The transducers may use energy conversion methods such as dynamic conversion, electrostatic, piezoelectric, magnetodynamic, pneumatic, electromagnetic, or the like.

In some embodiments, the speaker modules 11 may be divided into bone conduction speaker modules and air conduction speaker modules according to the sound generation principle used by these speaker modules. In some embodiments, speaker module 11 may include one or more bone conduction speakers. In some embodiments, speaker module 11 may include one or more air conduction speakers 113. In some embodiments, speaker module 11 may comprise a combination of one or more bone conduction speakers and one or more air conduction speakers 113 at the same time.

In some embodiments, sound receiving module 16 may include one or more microphones. In some embodiments, the one or more microphones may be air conduction microphones. In some embodiments, the one or more microphones may be bone conduction microphones. In some embodiments, the collection of said one or more microphones may be a combination of bone conduction microphones and air conduction microphones.

Microphones can be configured to receive an acoustic signal (also referred to as a voice signal) and convert that acoustic signal into a signal containing audio information (eg, an electrical signal). For example, microphones can receive mechanical vibrations generated by a voice signal and convert these mechanical vibrations into an electrical signal. For ease of description, the mechanical vibrations generated when the user creates a voice signal (speaks) may be simply referred to as mechanical vibrations. In one or more embodiments of the present invention, a bone conduction microphone may be described by way of example.

A bone conduction microphone may be a receiving device (eg, a voice sensing device) capable of converting a mechanical vibration signal into an electrical signal. A mechanical vibration signal may refer to a signal generated by a part of the user's body when they speak. For convenience of understanding, a bone conduction microphone can be understood as a microphone device sensitive to bone conduction sound transmitted by mechanical vibrations, and this microphone is insensitive to air conduction sound transmitted through the air.

In some embodiments, when the user is wearing the acoustic input and output device 10, the bone conduction microphone may not be in direct contact with the human body. The mechanical vibration signal (eg, facial vibration) generated when the user speaks can be transmitted to the speaker modules 11 and further transmitted to the bone conduction microphone via these speaker modules 11 . The bone conduction microphone can further convert the body vibration signal into an electrical signal containing voice information. In some embodiments, when the user wears the acoustic input and output device 10, the bone conduction microphone may be in direct contact with the human body such that the mechanical vibration signal generated when the user speaks may be transmitted to the bone conduction microphone directly.

In some embodiments, the acoustic input and output device 10 may be a headset. For convenience of description, the present application describes the acoustic input and output device 10 as an example of a headset. In some embodiments, acoustic input and output device 10 may be a bone conduction headset such that audio input and output may be through bone conduction.

In some embodiments, the sound pickup module may be connected to the speaker module, and the sound pickup module wire group may be electrically connected to the remaining elements (e.g., the battery module) of the headset using bone conduction through the speaker module. In some embodiments, the sound receiver module 16 may be physically connected to the speaker module 11 by, for example, a swivel, clamp connection, welded connection, integral casting, or other suitable method.

In some embodiments, the sound receiving module 16 may be connected to the loudspeaker module 11 via a connector node 18. This connector node 18 can be a connector structure for physically connecting the components of the acoustic input and output device 10. In some embodiments, this connector 18 may include a connector configured to connect the sound receiver module 16 and the loudspeaker module 11.

In some embodiments, the implementation of the sound receiving module is connected to the loudspeaker module through a connecting element. For convenience of description, the sound receiving module and the connecting element can be considered as a single unit. Further, the sound receiving module and the connecting element as a whole can be considered as a microphone holder module. In some embodiments, the bone conduction headset may also include a microphone holder module, and this microphone holder module may be configured to receive audio. The microphone holder module may be configured to connect the loudspeaker module 11 and the sound receiving module, and have a structure that receives a user-generated audio signal. In some embodiments, there may be only one microphone holder module connected to one of the two speaker modules 11. For example, the microphone holder module may be connected to the speaker module 11 corresponding to the battery module 14. Of course, in other embodiments, each loudspeaker module 11 may be connected to its own microphone holder module.

In some embodiments, the implementation of the connecting element 181 may be a rigid element. The rigid element may be an element that has no resilience or whose resiliency is negligible. In some embodiments, the implementation of the connecting element 181 may be made of stainless steel, carbon fiber, aluminum alloy, or other similar material. In some embodiments, the implementation of the connecting element 181 may have a certain shape. For example, the connecting element 181 may be a narrow strip (for example, in the form of a rod). In some embodiments, the implementation of the connecting element 181 may have a certain bending radius. As shown in FIG. 4, the connecting element 181 may be a holder with a certain radius.

In some embodiments, the speaker modules 11 may allow the user to hear sound by generating metallic vibrations to transmit sound waves. The manner in which the speaker modules 11 transmit sound waves may be by using air conduction or bone conduction. Regardless of whether the sound waves are transmitted through bone conduction or through air conduction, the sound receiving module may or may not be directly connected to the loudspeaker module 11, and as a result, the vibrations generated by the loudspeaker module 11 may have an undesirable effect on the sound receiving module, reducing the sound quality. sound perceived by the sound receiving module.

In particular, taking a bone conduction speaker as an example, when the bone conduction speaker generates sound, mechanical vibrations of the connection assembly 18 and the speaker cabinet may be generated. This connector 18 and the loudspeaker case can transmit mechanical vibrations to the sound receiving module. The microphones of the sound receiving module can generate appropriate mechanical vibrations upon receiving said mechanical vibrations from a loudspeaker, and generate a signal containing audio information (eg, an electrical signal) based on these mechanical vibrations. As noted above, since the sound receiving module is directly or indirectly connected to the connector 18 and the speaker cabinet, mechanical vibrations of the connector 18 and the speaker cabinet may occur when the speaker 113 transmits sound waves. The connector assembly 18 and the loudspeaker case can transmit mechanical vibrations to the sound receiving module, so that the microphones of the sound receiving module can generate corresponding mechanical vibrations after receiving the mechanical vibrations generated by the loudspeaker, and generate a signal containing sound information (for example, an electrical signal) based on these mechanical vibrations.

Therefore, at least part of the mechanical vibrations generated by the loudspeaker modules 11 can be transmitted to the microphones of the sound receiving module to cause mechanical vibrations of the microphones of the sound receiving module. When the microphones of the sound pickup module and the speaker modules 11 operate at the same time, the speaker modules 11 can oscillate to transmit a voice signal (such as music) when the microphones of the sound pickup module receive a voice signal (i.e., receive a voice signal when the user speaks , by perceiving the vibrations of the skin and other elements during the user's conversation). The sound module microphones can receive many different mechanical vibrations at the same time. The microphones of the sound receiving module can receive voice signals transmitted by the speaker modules 11 that are different from the voice signal transmitted by the user, which affects the quality of the voice signal perceived by the microphones. In some embodiments, to reduce the undesirable effect of mechanical vibrations generated by the speaker modules 11 on the sound receiving module, the coupling element 181 may be configured to have a certain resiliency to reduce the vibration amplitude.

In some embodiments, the connection element 181 may be an elastic element 1811. The intensity of mechanical vibrations transmitted from the speaker modules 11 can be reduced due to the elasticity of this elastic element 1811, thereby improving the quality of the voice signal perceived by the microphones. As shown in FIG. 5, in some embodiments, the resilient member 1811 may be a resilient connecting rod 18111 such that the microphone holder module may include a resilient connecting rod 18111 and a sound receiving module 16. One end of the resilient connecting rod 18111 may be coupled to the loudspeaker module 11. The other end of this elastic connecting rod 18111 can be connected to the sound module 16.

In some embodiments, sound receiving module 16 may have one or more microphones. For example, the number of microphones in the sound receiving module 16 may be at least 2, and these microphones may be spaced apart. For example, one microphone may be located at the end of the sound receiver module 16 farthest from the loudspeaker module 11, and other microphones may be located on the same side of the sound receiver module 16 connected to this end, which can facilitate cooperation between multiple microphones, thereby reducing noise and improving the perceived sound quality. The speaker modules 11 can convert the audio signal into mechanical vibrations, in other words, when the speaker modules 11 reproduce the corresponding audio signal, the audio range of the audio signal can cause the speaker 113 to generate corresponding vibrations.

In some embodiments, the resilient element 1811 may be configured to cause the audio band vibrations generated by the speaker modules 11 to decay as the vibrations travel from the first end of the resilient element 1811 (e.g., the resilient connecting rod 18111 of this resilient element 1811) to the second end of this elastic member 1811. In particular, the audio range vibrations generated by the elastic connecting rod 18111 and the audio range vibrations generated by the loudspeaker module 11 can pass from the first end of the elastic connecting rod 18111 (i.e., one end connected to the module 11 loudspeaker) on the elastic connecting rod 18111. The average value of the amplitude attenuation coefficient at the considered end (ie, at one end connected to the sound receiving module 16) can be not less than 35%. In some embodiments, this average amplitude attenuation factor value may be at least 45%. In some embodiments, this average amplitude attenuation factor value may be at least 50%. In some embodiments, this average amplitude attenuation factor value may be at least 55%. In some embodiments, the average value of the amplitude attenuation factor may be at least 60%. In some embodiments, the average value of the amplitude attenuation factor may be at least 70%.

During actual operation, the mechanical vibrations generated by the speaker modules 11 in the acoustic input and output device 10 may have a negative effect on the sound perception of the microphone holder module, such as creating an echo. More details regarding the effect of the speaker modules 11 on the microphone holder module can be found in other embodiments of the present invention described here. For the above reasons, the elastic connecting rod 18111 can be configured so that the average value of the damping ratio of the amplitude of vibrations in the audio range generated by the loudspeaker modules 11 is not less than 35% during the passage of vibrations from one end of the elastic connecting rod 18111 to the other end of the elastic connecting rod. rod 18111, so that the elastic connecting rod 18111 can effectively absorb vibrations during transmission of these vibrations and reduce the amplitude of vibrations of the elastic connecting rod 18111 passing from one end to the other end, thereby reducing vibrations of the sound receiving module 16, driven by vibrations generated by the loudspeaker modules 11 , and effectively reducing the effect of oscillation of the speaker units 11 on the sound perception effect of the sound receiving unit 16, and improving the sound quality perceived by the sound receiving unit.

In some embodiments, the reduction in vibration amplitude can be achieved due to the structure of the elastic element 1811 and/or the material of the elastic element 1811. In some embodiments, the implementation of the elasticity of the specified elastic element 1811 can be implemented through an appropriate choice of structure. The elastic element 1811 may have an elastic structure, even if the material of this elastic element 1811 may have a high stiffness, elasticity can also be realized by choosing the structure of the elastic element 1811. In some embodiments, the implementation of the elastic element 1811 may have, without limitation, a sheet form, a strip form , a column shape, a spring-type structure, an annular shape, an annular-type cross-sectional structure, or the like. In some embodiments, the resiliency of said resilient member 1811 may be determined by the material from which the resilient member 1811 is made. For example, the resilient member 1811 may be made from a nickel-titanium alloy, this nickel-titanium alloy having significant resilience and shape memory. This nickel-titanium alloy can automatically return to a state close to its original shape before the deformation of the alloy.

As shown in FIG. 5, for example, assuming that the elastic element 1811 is an elastic connecting rod 18111, in some embodiments, this elastic connecting rod 18111 may contain an elastic metal thread 18113 configured to create elasticity, so that this elastic metal thread 18113 can be configured as skeleton of the elastic connecting rod 18111 so that this elastic connecting rod 18111 maintains a fixed shape. The elastic connecting rod 18111 may also include plug-in sections 182 connected to the two ends of the elastic metal thread 18113, respectively. In other words, each of the two ends of the elastic metal thread 18113 can be connected to its insert section 182, respectively. One of these plug-in sections 182 can be configured to match and insert into the sound receiving module 16. The other plug-in section 182 can be configured to match and insert into the loudspeaker module 11. In some embodiments, the insertion sections 182 may be insertion halves, and their respective insertion grooves for these halves may be located on the loudspeaker modules 11 and the sound receiver module 16. In some embodiments, the insertion sections 182 may be magnets. Magnetic circuits may be provided on the speaker modules 11 and the sound receiver module 16 so that the speaker modules 11 and the sound receiver module 16 can be connected to the insert sections 182 by means of magnetic forces. In some embodiments, the insert structures of the two insert sections 182 may be the same or different. For example, the plug-in sections 182 connected to the loudspeaker modules 11 may be plug-in coupling halves, and the plug-in sections 182 connected to the sound-receiving module 16 may be magnets. Interfaces can be assigned to the insert structures corresponding to the sound receiving module 16 and the loudspeaker modules 11 . In some embodiments, the insert sections 182 may be directly connected to the sound receiver module 16 and to the loudspeaker modules 11 through, for example, swivel joints, latches, welded joints, integral molding, or the like. In some embodiments, the resilient metal filament 18113 may be in any suitable shape, which may be, but is not limited to, a strip shape, a column shape, a sheet shape. The present invention may not be limited in this matter, so that the shape of the elastic metal filament 18113 can be determined according to the actual situation.

In some embodiments, the implementation of the elastic metal filament 18113 may have a strong ability to recover the shape after deformation, in other words, after deformation, the elastic metal filament 18113 can return to its original shape. In some embodiments, the implementation of the modulus of elasticity of the specified elastic metal thread 18113 may be in the range from 70 GPa to 90 GPa. In some embodiments, the implementation of the modulus of elasticity of the specified elastic metal thread 18113 may be in the range from 75 GPa to 85 GPa. In some embodiments, the implementation of the modulus of elasticity of the specified elastic metal thread 18113 may be in the range from 80 GPa to 84 GPa. In some embodiments, the implementation of the modulus of elasticity of the specified elastic metal thread 18113 may be in the range from 81 GPa to 83 GPa.

In some embodiments, the material of the resilient metal filament 18113 may be spring steel, titanium, or another similar material. In some embodiments, the elastic metal filament material 18113 may be a nickel-titanium alloy. This nickel-titanium alloy can have a significant ability to recover from deformation and effectively increase the service life. In other embodiments, if the modulus of elasticity of said elastic metal filament 18113 is set in the range of 70 GPa to 90 GPa, the elastic metal filament 18113 can have a good vibration absorbing ability, which can satisfy the requirements for the ability of the connecting member 181 to absorb vibrations, thereby improving the perception quality. sound through the sound receiving module 16.

It should be noted that, in addition to metallic materials, a non-metallic material can be used as a material for making the skeleton of the connecting member 181, for example, an elastic thread made of plastic, rubber, or other materials.

In some embodiments, if the elastic element 1811 is exposed to the outside, its use for an extended period of time may cause loss of the elastic element 1811. member 1811 contacts rainwater and rubs against the wearer's skin, which can also reduce the life of the elastic member 1811. Therefore, in some embodiments, a structure may be located outside the elastic member 1811 to protect the elastic member 1811.

As shown in FIG. 5, in some embodiments, the connector assembly 18 may also include an elastic cover layer 183 covering the periphery of the elastic element 1811. This elastic cover layer 183 may have a certain elasticity such that the average value of the damping coefficient of the vibration amplitude in the audio frequency range generated by the loudspeaker modules 11 can be further enhanced when the audio frequency vibrations travel from the connection node to the sound receiving module. In some embodiments, the elastic cover layer 183 may be part of the elastic element 1811, for example, the elastic cover layer 183 may be integral with the elastic element 1811. In some embodiments, the elastic cover layer 183 may be manufactured separately from the elastic element 1811 and then assembled with elastic element.

For convenience of description, for example, still assuming that the elastic element 1811 is an elastic connecting rod, in particular, such an elastic connecting rod 18111 may include an elastic cover layer 183 covering the periphery of the elastic metal thread 18113. In some embodiments, the implementation of the elastic cover layer 183 may only cover a portion of the periphery of the elastic metal filament 18113. In some embodiments, the elastic cover layer 183 may cover more than just the periphery of the elastic metal filament 18113, in other words, completely cover the elastic metal filament 18113. In some embodiments, the elastic cover layer 183 may further cover part of the insert sections 182, and can further protect the elastic metal thread 18113 and the insert sections 182 at the same time. In some embodiments, the material of the elastic cover layer 183 may be silica gel, rubber, plastic, or other similar material. In some embodiments, a leading channel (not shown in the drawing) may be provided on the elastic cover layer 183, extending in the direction of the length of the elastic cover layer 183 (such as the connection direction of the two insert sections 182 shown in Fig. 5), so that this the leading channel and the elastic metal thread 18113 can be arranged in parallel and at a distance from one another. Insert sections 182 can be provided with hidden grooves for wires (not shown). The group of wires for connection to the sound module 16 may enter the lead channel through the hidden wire grooves of the adjacent insert section 182, and further enter the loudspeaker modules 11 through other insert sections 182. This group of wires can be configured to electrically connect the sound module 16 to other modules (for example, with a battery module 14 and a control circuit module 15). In some embodiments, the implementation of the modulus of elasticity of the specified elastic cover layer 183 may be in the range from 0.5 GPa to 2 GPa. In some embodiments, the implementation of the modulus of elasticity of the specified elastic cover layer 183 may be in the range from 0.8 GPa to 1.5 GPa. In some embodiments, the implementation of the modulus of elasticity of the specified elastic cover layer 183 may be in the range from 1.2 GPa to 1.4 GPa. In this embodiment, due to the establishment of the elastic modulus of the specified elastic cover layer 183 within 0.5 GPa ~ 2 GPa, and due to the fact that this elastic cover layer 183 covers the outer surface of the elastic metal thread 18113, further absorption of vibrations transmitted outside the elastic 18113 metal thread, which creates the effect of coordinated internal and external vibration absorption, which can greatly enhance the vibration absorption effect of the microphone holder unit, effectively reduce the vibration passing to the sound receiving unit 16, and improve the quality of sound perception.

It should be noted that the above description of the connecting element 181 can only be given for convenience, and that one or more embodiments of the present invention may not be limited to this. It should be noted that after understanding the design principles of the connecting element 181, a person skilled in the art will be able to arbitrarily combine various components, or even eliminate one or more elements, without deviating from these principles. For example, the elastic cover layer 183 may be omitted or replaced with a rigid body. For example, when the connecting element 181 is not the elastic element 1811, or this elastic element 1811 is not the elastic connecting rod 18111, the periphery of this connecting element may still be covered with an elastic cover layer 183. For example, the elastic element 1811 may be an elastic connecting part. All such variations fall within the protection scope of one or more embodiments of the present invention.

In some embodiments, the sound receiver module may be electrically coupled to other headset modules using bone conduction to facilitate user control of the sound receiver module. For example, the user may choose to turn off the sound pickup function of the sound pickup module. As another example, the user may adjust the volume of the sound received by the sound receiving module. In some embodiments, the sound pickup module may have a set of wires electrically connected to other headset modules using bone conduction. The sound pickup module can be electrically connected to the remaining one or more headset modules using bone conduction through a group of wires of this sound pickup module 16. The modules mentioned above can be connected to the loudspeaker modules 11. Therefore, the group of wires of the sound receiving module 16 can be electrically connected to the modules mentioned above via the loudspeaker modules 11 . The modules mentioned above may be electrically connected to the remaining one or more headset modules using bone conduction through the wire set of the sound pickup module 16. These modules mentioned above can be connected to the loudspeaker modules 11. Therefore, the group of wires of the sound receiving module 16 can be electrically connected to the modules mentioned above via the loudspeaker modules 11 .

As shown in FIG. 6, in some embodiments, the loudspeaker module 11 may include a first loudspeaker cabinet section 111, a second loudspeaker cabinet section 112, and a loudspeaker 113. The first loudspeaker cabinet section 111 may be matched and connected to the second loudspeaker cabinet section 112 to form an interior space 110 in which a loudspeaker 113 is placed. A first through hole 1110 and a second through hole 1111 may be provided in the first section of the speaker case, separated by a certain interval, so that the first through hole 1110 and the second through hole 1111 can communicate with the interior 110. The wire group of the sound receiving module 16 can pass through the first through hole 1110, the interior 110 and the second through hole 1111.

In some embodiments, the implementation of the sound receiving module 16 may be fixed relative to the speaker module 11. In other words, the sound receiving module 16 may not move relative to the loudspeaker module 11 after this sound receiving module 16 has been matched and connected to the loudspeaker module 11. In some embodiments, the implementation of the sound receiving module may be directly connected to the first section of the loudspeaker housing, and this connection may not be described here. In some embodiments, the implementation of the first section 111 of the speaker housing can be matched and connected to one end of the connecting element 181 (for example, the elastic element 1811). In some embodiments, the first section 111 of the loudspeaker housing may be matched and connected to one end of the elastic connecting rod 18111.

In some embodiments, when the sound pickup module 16 is closer to the sound-generating part of the user's body, such as the vocal cords, throat, mouth, nasal cavity, or other similar body part, the microphones of the sound pickup module 16 can receive a higher amplitude vibration signal. The sound quality of the audio signal picked up by the microphones may be higher and the volume may be louder. For example, when the sound receiving module 16 is aligned with the user's mouth, the radio effect may be better. When the user does not need to use the microphone function, such as when the user is eating, the position of the sound receiving module 16 can be changed. Therefore, in some embodiments, the sound receiver module 16 may be configured to be pivotable relative to the speaker module 11 to facilitate adjustment of the position of the sound receiver module 16 by the user, thereby improving user comfort and quality of service.

In some embodiments, in order to assist in adjusting the operating position of the sound receiving module, the sound receiving module may be configured to be pivotable relative to the first section 111 of the speaker housing. In some embodiments, the speaker module 11 may include a pivot member 184. The first speaker housing section 111 may be configured with a first through hole 1110.

In some embodiments, the implementation of the rotary element 184 may be combined with the connecting element 181 (for example, the elastic element 1811) in one or more of the options described above. For example, the sound receiving module 16 may be connected to the rotary element 184 via the coupling element 181, so that rotation relative to the speaker module 11 can be made through the connection between the rotary element 184 and the speaker module 11. In some embodiments, the implementation of the specified connecting element 181 may be an elastic element 1811. For example, this elastic element 1811 may be an elastic connecting rod 18111. The present invention can be illustrated using a combination of a rotary element 184 and an elastic connecting rod 18111.

In some embodiments, the pivot element 184 may be inserted into the first through hole 1110 so that it can rotate in the hole, and the insert section 182 can be matched and inserted into this pivot element 184 so that the sound receiving module can rotate relative to the first section 111 of the body loudspeaker.

The second through hole 1111 can be created in the first section 111 of the loudspeaker case at some distance from the first through hole 1110. The second through hole 1111 can be matched and docked with the remaining nodes and modules (for example, the node 12 of the earpiece) headset using bone conduction so that this loudspeaker module 11 can be permanently connected to the rest of the assemblies and headset modules using bone conduction (for example, to the earhook node 12). Said first through hole 1110 and second through hole 1111 may communicate with interior space 110.

As shown in FIG. 8, in some embodiments, pivot member 184 may include a wire passage section 1841 and pivot section 1842 coupled to one another. The pivot section 1842 may be inserted into the first through hole 1110, and the sound receiver module 16 may be connected to the wire section so that the group of wires of the sound receiver module 16 will pass through the wire path section 1841 and cross the first through hole 1110 through the pivot section 1842.

In some embodiments, at the end of the first through hole 1110 of the first section 111 of the loudspeaker housing, an access segment (not shown in the drawing) protruding away from the first through hole 1110 can be located. This access segment can communicate with the first through hole 1110. The rotary section 1842 can be stretched over the peripheral wall of the access segment to implement a rotational connection with the loudspeaker module 11. More details regarding section 1841 for the passage of wires and rotary section 1842 can be found elsewhere in this description.

In some embodiments, the implementation of the first section 111 of the speaker housing may include a bottom wall 1112 and a side wall 1113 connected to one another. The side wall 1113 may surround and connect to the bottom wall 1112, and the second speaker housing section 112 may cover one side of the side wall 1113 away from the bottom wall 1112 to form an interior space 110 where the speaker 113 can be placed. In some embodiments, implementation of the first through hole 1110 can be made in the bottom wall 1112, and the second through hole 1111 can be made in the side wall 1113. In some embodiments, the first through hole 1110 can be created in one side of the bottom wall 1112, close to the second through hole 1111 so that the first through hole 1110 may be close to the second through hole 1111.

In some embodiments, when the sound receiver module 16 is directly connected to the speaker module 11 (for example, with the first section 111 of the loudspeaker housing) or this sound receiver module 16 is connected to the speaker module 11 through the connecting node 18 (for example, through the elastic element 1811), if the surface connection between the connection node 18 or the sound receiver module 16 and the first section 111 of the loudspeaker case is flat, the first section 111 of the speaker case may interfere with the rotation of the sound receiver module 16. Therefore, in some embodiments, the bottom wall 1112 may have a first raised portion 1114 protruding away from the interior space 110, and the first through hole 1110 may be created in this first raised portion 1114. The side wall 1113 may include a second raised portion 1115, protruding away from interior space 110. A second through hole 1111 may be created in this second raised portion 1115.

In some embodiments, an angle may be formed between the direction of the bulge of the first bulge 1114 and the direction of the bulge of the second bulge 1115. In other words, this certain angle may be the angle between the axial direction of the first raised portion 1114 and the axial direction of the second raised portion 1115. In some embodiments, the direction of the bulge of the first raised portion 1114 may be perpendicular to the direction of the bulge of the second raised portion 1115. In some embodiments, the implementation of the connection between the first convex section 1114 and the second convex section 1115 may be an arcuate connection, in other words, the connecting surface between the first convex section 1114 and the second convex section 1115 may be an arched surface. In some embodiments, the implementation of the connecting surface between the first convex section 1114 and the second convex section 1115 may be flat.

In this embodiment, the structural strength and structural stability of the first section 111 of the loudspeaker housing can be improved by providing the first convex section 1114 and the second convex section 1115 located on the bottom wall 1112 and on the side wall 1113, respectively. The direction of the bulge of the first bulge 1114 may be perpendicular to the direction of the bulge of the second bulge 1115, and the connection between the first bulge 1114 and the second bulge 1115 may be an arcuate connection. The pivot member 184 may be inserted into the first through hole 1110 in the first raised portion 1114. Rotation of the microphone holder module may be unimpeded by the first speaker body section 111 having a first raised portion 1114 of an appropriate height. Possible mutual interference between the temple assembly 12 and the microphone holder module can be reduced in the case where the convex direction of the convex portion 1114 and the convex direction of the second convex portion 1115 are perpendicular to one another.

In this embodiment, the sound receiving module 16 can be connected to other relevant modules and blocks of the acoustic input and output device 10 through a suitable group of wires, for example, to the battery module 14 or the control circuit module 15. In addition to facilitating control of the sound receiving module as described in the above embodiments, the received audio signal may be passed to the respective modules for further processing.

In some embodiments, a group of wires of the microphone holder module (for example, the structure formed by the connecting element 181 and the sound receiving module 16) can pass through the elastic cover layer 183 on the elastic connecting rod 18111 and can be brought out through the insert sections 182. In some embodiments, the implementation on A leading channel (not shown in the drawing) can be located in the elastic cover layer 183, so that the group of wires of the sound-receiving module 16 can pass through this leading channel. The group of wires of the sound-receiving module 16 can be brought out by passing through the plug-in sections 182 and introduced into the first section 111 of the loudspeaker case. In particular, the group of wires of the sound receiving module 16 may pass through the first through hole 1110 and reach the interior of the second through hole 1111 through the interior 110. In some embodiments, the group of wires of the sound receiving module 16 may further exit the second through hole 1111, enter other modules headset using bone conduction (eg, into the containing space 120 of the earpiece assembly 12), and connect to other headset modules using bone conduction (eg, battery module 14 or control circuit module 15) electrically.

In actual use, the microphone holder module (ie, the structure formed by the sound receiving module 16 and the connecting member 181) can be rotated relative to the first section 111 of the speaker housing. In some embodiments, when the sound receiver 16 is rotated, the wire group of that sound receiver 16 may move such that the rotation of the sound receiver 16 may be limited due to improper movement of the sound receiver 16 wire group. For example, winding or excessive bending of the wire group may not allow the sound receiver module 16 to continue rotating. In some embodiments, since the group of wires of the sound receiver module 16 that has entered the first through hole 1110 may contact the speaker module 11 directly or indirectly (i.e., contact the first section 111 of the speaker box), this the wire group of the sound receiver module can also transmit the mechanical vibrations generated by the loudspeaker module 11 to the sound receiver module 16, which in turn adversely affects the sound perception of the sound receiver module 16 and the stability of the electrical connection. In accordance with the above reasons, the present invention provides speaker modules 11 to solve the above technical problems.

In some embodiments, the loudspeaker module 11 may further comprise a wire attachment configured to lock the group of wires of the sound module 16 passing through the first through hole 1110 and reaching the second through hole 1111, therefore limiting the movement of the group of wires due to the rotation of the sound module 16 relative to the first section 111 of the loudspeaker case, reduces the wear of this group of wires and limits the amplitude of mechanical vibrations of the group of wires of the sound receiving module 16 to improve the sound perception effect of the sound receiving module 16.

In some embodiments, the wire attachment assembly may include a clamping component 115 configured to tightly clamp the wire bundle of the sound receiver 16, thereby reducing the amplitude of mechanical vibrations of the wire bundle of the sound receiver 16 and limiting the movements of the wire bundle. In particular, the pressing element may be located in the inner space 110. In other words, the pressing element may tightly clamp the group of wires of the sound receiving module 16 in the first section 111 of the loudspeaker case.

As shown in FIG. 7, in some embodiments, the pressing component 115 may include a first pressing element 1151 configured to press and hold the group of wires of the sound receiving module 16. hold the group of wires of the sound receiving module 16 passing through the first through hole 1110 and reaching the second through hole 1111. In some embodiments, the first pressing element 1151 may partially cover the first through hole 1110, for example, the first pressing element 1151 may partially cover the first through hole 1110, so that only part of the lumen of the hole remains open as a conduit for the group of wires to pass through. In some embodiments, the first pressing element 1151 may completely cover the first through hole 1110. For example, the first pressing element 1151 may completely cover the first through hole 1110, and the group of wires may enter the interior 110 through a gap to connect between the first pressing element 1151 and the first through hole 1110. In some embodiments, a through hole (not shown in the drawing) for passing the group of wires of the sound receiving module 16 can be made in the first pressing element 1151, so that this group of wires of the sound receiving module 16 can enter the internal space 110 through the through hole in the first pressing element 1151, so that this group of wires passes through the connection gap between the first pressing element 1151 and the first through hole 1110, while the first pressing element 1151 can closely contact the first through hole 1110.

The clamping component 115 can limit the movement space for the wire group of the sound receiver module 16, reduce the shaking or movement of the wire group of the sound receiver module 16, and further reduce the mechanical vibration generated by vibration of the speaker module 11 and the mechanical vibration transmitted to the sound receiver module 14. Sound reception by the sound receiver module 16 and the stability of the electrical performance can also be improved. In addition, pinching and holding by the pressing member 115 can reduce friction between the wire group of the sound pickup module 16 and the first section 111 of the speaker cabinet, so that the wire group of the sound pickup module 16 can be protected.

In some embodiments, the clamping component 115 may further comprise a second clamping element 1152. This second clamping element 1152 may cooperate with the first clamping element 1151 in the embodiments above such that the wire group is tightly clamped between the clamping elements. In some embodiments, the clamping component may include only the second clamping element 1152, so that the tight compression of the group of wires can also be realized by the second clamping element 1152. In particular, the location of the second clamping element 1152 may be the same or similar to the first clamping element 1151. For example, the second clamp element 1152 may at least partially cover the first through hole 1110, or a through hole may be created in the second clamp element 1152 itself for the passage of a group of wires.

In some embodiments, the pressure component may include the first pressure element 1151 and the second pressure element 1152 simultaneously to enhance the effect of limiting movements of the group of wires of the sound receiving module 16. In some embodiments, both the first pressure element 1151 and the second pressure element 1152 may be leaf elements. The first pressure element 1151 and the second pressure element 1152 are located one on top of the other, and the second pressure element 1152 may be located further from the first through hole 1110 than the first pressure element 1151. In this embodiment, the first pressure element 1151 may be configured as a structure, directly contacting the group of wires of the sound receiving module 16 and firmly pressing this group of wires of the sound receiving module 16. The second pressing element 1152 can be configured as a structure that fixes the first pressing element 1151 and presses the group of wires to the sound receiving module 16 indirectly, thereby increasing the limiting effect of the pressing element on the group of wires of the sound receiving module 16. In some embodiments, the stiffness of the second pressure element 1152 may be greater than the rigidity of the first pressure element 1151. Since the first pressure element 1151 directly contacts the group of sound wires, receiving module 16, this first pressing element 1151 with less rigidity can reduce the wear of the wire group of the sound receiving module 16, and the second pressing element 1152 with a certain rigidity can make the first pressing element 1151 more stable, thereby reducing the movements and amplitude of mechanical vibrations of the wire group of the sound receiving module 16. In some embodiments, the clamping component may comprise multiple clamping elements or a combination of several clamping elements at the same time. The pressure element combination may comprise at least two different pressure elements.

In some embodiments, the pressing component 115 may comprise a hard coating and an elastomeric material stacked one on top of the other. A hard coating may be used as the first pressing element 1151 and an elastomeric material may be used as the second pressing element 1152. with the group of wires of the sound-receiving module 16. The rigidity of the hard coating may be greater than the rigidity of the elastomeric material. The hard cover may contact the wire group of the sound module 16 to press and hold the elastomeric material. Since the rigidity of the hard coating is greater than the rigidity of the elastomeric material, a hard coating with a higher rigidity can provide a firm grip and hold on the wire bundle of the sound receiver 16, and an elastomeric material with less rigidity can improve the absorption of movement and mechanical vibrations of the wire bundle of the sound receiver 16, thereby reducing mechanical vibrations of the wire group of the sound receiving module 16 to play the role of buffer and protection.

In some embodiments, the implementation of the hard coating may be metal, ceramic, plastic, or made from another similar material. For example, the hard cover may be made of stainless steel. In some embodiments, the elastomeric material may be a plastic, silica gel, rubber sheet, fibrous material, or other similar material, for example, the elastomer may be a foam.

In some embodiments, the wire attachment assembly may secure the sound pickup module's wire group by means or structures other than the pressure component 115 in one or more of the above embodiments.

In some embodiments, the wire attachment assembly may include one or more clips located in the interior space 110, and these clips can be used to secure the group of wires of the sound module 16. In particular, these one or more clips can be fixedly fixed to the inner wall of the first section 111 of the loudspeaker housing. The sound receiver wire group 16 may be clamped after the sound receiver wire group 16 has entered the interior 110 through the first through hole 1110. module 16 can smoothly reach the second through hole 1111 through the interior 110. Since the group of wires of the sound receiver module 16 is fixed with clips, the rotation of the sound receiver module 16 relative to the first section 111 of the speaker cabinet cannot be performed. In the present embodiment, the group of wires of the sound receiving module 16 can also be fixed with clips. The volumes of these clips can be kept relatively small to reduce the space they occupy, which can reduce the volume of the entire loudspeaker module.

In some embodiments, the clamping element may be physically connected to the first section 111 of the loudspeaker housing by, for example, a bonding connection, a pin connection, an integral molding, or other similar method. To ensure that the pressing component 115 accurately presses the group of wires of the sound receiving module 16, and further improving the strength of the connection between the pressing component 115 and the first section 111 of the loudspeaker housing and service life, in some embodiments, the implementation of the loudspeaker module 11 may further include positioning elements 1117 located on the first section 111 of the loudspeaker housing at a certain interval. The first pressing element 1151 and/or the second pressing element 1152 may be attached to the first section 111 of the loudspeaker housing via the positioning elements 1117.

In some embodiments, the positioning elements 1117 may be convex cylinders 11171 located on the periphery of the first through hole 1110 and protruding into the interior space 110.

In particular, if we take the options shown in Fig. 9, by way of example, a plurality of convex cylinders 11171 may be positioned at the periphery of the first through hole 1110 in the first speaker cabinet section 111 and protrude into the interior 110, and these plural convex cylinders 11171 may be positioning members 1117 fixing the pressing member 115. These several convex cylinders 11171 may be located on the periphery of the first through hole 1110 at some intervals. In some embodiments, the second pressing element 1152 may be fixedly connected to the plurality of positioning elements 1117, and the first pressing element 1151 may be fixed among the plurality of positioning elements 1117. material 1152 may be positioned among said plurality of convex cylinders 11171 without being directly connected to the plurality of convex cylinders 11171. For example, the number of convex cylinders 11171 may be three. The elastomeric material 1152 can be compressed and held between the first through hole 1110 and the hard cover due to the fact that this hard cover is fixed by several convex cylinders 11171 located around the periphery of the first through hole 1110. The elastomeric material can press and hold the group of wires of the sound module 16, and multiple convex cylinders 11171 can improve the stability of the hard cover 1151, which in turn improves the stability of the elastomeric material 1152 in contact with the wire group.

It should be noted that the positioning elements 1117 may be other structures or shapes for fixing the pressing component 115 in addition to the convex cylinders 11171, as in the embodiments described above. For example, the positioning elements 1117 may be located on a position limiting board (not shown) in the first section 111 of the loudspeaker body, so that this position limiting board can restrict the movement of the pressing component 115 (for example, hard coating or elastomeric material) . This pressing component 115 can be limited in a position closely contacting the first through hole so that this pressing component 115 tightly presses the group of wires of the sound receiving module 16.

The group of wires of the sound-receiving module 16 can be fixed by the wire fastener. For example, the wire group of the sound receiver 16 can be pressed and held by the pressure component 115, the mechanical vibration of the wire group of the sound receiver 16 generated by the mechanical vibration of the loudspeaker module 11 can be reduced, the stability of the wire group during the rotation of the sound receiver 16 can be improved, the wear of this group of wires of the sound receiving module 16 can be reduced, and the service life of this group of wires can also be increased.

In some embodiments, the sound receiver module 16 may also have good stability during rotation, in other words, the coordinated design of the rotary element 184 and the first through hole 1110 may have a greater impact on the rotational stability of the sound receiver module 16. The following is an example of a description of the design of the rotary element 184.

As shown in FIG. 8, in some embodiments, pivot member 184 may include a wire passage section 1841 and pivot section 1842 coupled to one another. Section 1841 for the passage of wires can be configured to connect with sound module 16 (or connector 181). Rotary section 1842 can be inserted into the first through hole 1110 and can be rotated relative to the first section 111 of the speaker housing. The group of wires of the sound receiving module 16 may enter the interior space 110 through a section 1841 for the passage of wires and a rotary section 1842. In some embodiments, the section for the passage of wires 1841 may be configured with a first hollow segment 18410. The rotary section 1842 may be configured with a second hollow segment 18420 in the axial direction. The first hollow segment 18410 may communicate with the second hollow segment 18420.

In some embodiments, a connector 181 (e.g., a resilient member 1811) may be matched and connected to the wire passage section 1841, and the group of wires of the sound receiving module 16 may enter the first through hole 1110 through the connector 181, the wire passage section 1841 ( the first hollow segment 18410 section 1841 for passing wires) and the rotary section 1842 (the second hollow segment 18420 of the rotary section 1842) in series.

In some embodiments, connector 18 may be a matching connector configured to match and connect connector 181 (eg, resilient element 1811) to section 1841 for passing wires. For example, one end of the connector 181 facing away from the sound receiving module 16 and one end of the wire passage section 1841 facing away from the pivot section 1842 may be configured with the first matching connector and the second matching connector and mutually matched. When the first matching connector is matched and connected to the second matching connector, the wire passage section 1841 can be secured relative to the connector 181.

In some embodiments, the implementation of the first matching connecting element may be plug-in sections 182 in one or more of the above embodiments. Plug-in sections 182 (eg, plug-in sections 182 of connector 181) of the microphone holder module (eg, the structure formed by connector 181 and sound-receiving module 16) can be inserted into the first hollow segment 18410 of section 1841 to pass wires. When the connecting element 181 is connected to the rotary element 184, the group of wires of the sound module 16 can enter the interior 110 through the first hollow segment 18410 and the second hollow segment 18420. In some embodiments, the insert sections 182 can be configured with an insert hollow segment (not shown in drawing). The plug-in hollow segment can be pulled over the periphery of the first hollow segment 18410 of the section 1841 for the passage of wires, and the group of wires of the sound receiving module 16 can be inserted into the first hollow segment 18410 through the plug-in hollow segment.

In some embodiments, the angle between the extension direction of the first hollow segment 18410 and the extension direction of the second hollow segment 18420 may be less than 180°. In some embodiments, the angle between the extension direction of the first hollow segment 18410 and the extension direction of the second hollow segment 18420 may be less than 170°. In some embodiments, the angle between the extension direction of the first hollow segment 18410 and the extension direction of the second hollow segment 18420 may be less than 160°. In some embodiments, the angle between the extension direction of the first hollow segment 18410 and the extension direction of the second hollow segment 18420 may be less than 150°.

When a user wears a bone conduction headset, the direction in which the sound receiving module 16 faces can be adjusted by turning the rotary member to obtain different levels of radio effect. In some embodiments, it may be necessary for the user to precisely place the sound receiving module 16 in a predetermined position, such as orienting it to the user's mouth. In some embodiments, when the user rotates the sound receiving module 16 to a certain position, the sound receiving module 16 may remain in that position. For example, when the user no longer needs to use the microphone function, the user may turn the sound pickup module 16 to the side and leave the sound pickup module 16 so that it points away from the user's mouth. Therefore, it may also be necessary to design the rotatable member such that the rotatable section 1842 cannot inadvertently rotate about the first through hole.

In some embodiments, the damping groove 1843 may be located in the circumferential direction of the rotary section 1842. The connecting assembly 18 may further include a damping element 116 located in this damping groove 1843. The damping element 116 may contact the inner wall of the first through hole 1110 to dampen the rotary section 1842 due to contact friction. In this embodiment, when the rotary section 1842 can rotate relative to the first section 111 of the speaker cabinet, the damping element 116 can contact the inner wall of the first through hole 1110 to dampen the rotation. In the process of adjusting the sound receiving module 16 by the user, the user can feel the damping change, and the adjustment accuracy of the sound receiving module 16 can be improved. At the same time, when the user completes the adjustment, the presence of the swivel damping can keep the swivel section 1842 and the sound receiving module 16 in a certain position without the possibility of inadvertent rotation, to further improve the user's convenience.

As shown in FIG. 8, in some embodiments, the rotary section 1842 may include a rotary main block 18421, as well as a first stop 18422 and a second stop 18423 that protrude from two ends of the rotary main block 18421 and may be located along the radial direction of the rotary main block 18421, respectively. . In some embodiments, the rotary main block 18421 may be inserted into the first through hole 1110. The first stop 18422 and the second stop 18423 may abut two sides of the first section 111 of the speaker housing, respectively, to restrict movement of the rotary section 1842 relative to the first section 111 loudspeaker housing in the axial direction.

In some embodiments, the rotary main block 18421 may be configured in a cylindrical shape and the second hollow segment 18420 may be oriented in the axis direction of the rotary main block 18421. In some embodiments, the first stop 18422 and the second stop 18423 may be located on the periphery of the rotary main block. main block 18421, which has an annular shape or an open loop shape. In particular, the first stop 18422 may be located further from the wire section 1841 than the second stop 18423, and the second stop 18423 may be located closer to the wire section 1841 than the first stop 18422. In particular, the first the stop stop 18422 and the second stop stop 18423 may abut two sides of the first through hole 1110 of the first section 111 of the loudspeaker box, respectively, in other words, one side of the inner space 110 and the other side of this inner space 110. The first stop stop 18422 and the second stop stop the stop 18423 located at the two ends of the rotary main block 18421 and abutting against two sides of the first section 111 of the loudspeaker body can effectively limit the movement of the rotary section 1842 in the axial direction, thereby preventing the rotary section 1842 from rotating in the first through hole 1110 so that improve cornering stability.

In some embodiments, the first stop 18422 and the second stop 18423 may be combined with a damping element (eg, damping element 116 and damping groove 1843) in one or more of the above embodiments. As shown in FIG. 8 and FIG. 9, in some embodiments, in order to further enhance the rotational stability of the sound receiving module 16, the pivot section 1842 may be configured with a damping groove 1843. main block 18421 in the circumferential direction. The speaker module 11 may include a damping element 116. For example, damping element 116 may be a damping ring nested in a damping groove 1843. Said damping element 116 (for example, a damping ring) may be nested in a damping groove 1843 and may be in contact with the inner wall of the first through hole 1110 for damping the rotary section 1842 due to contact friction to prevent rotation. The inner wall of the first through hole 1110, in other words, the bottom wall, may surround a portion of the first through hole 1110. A damping element 116 nested in the damping groove 1843 and damping the rotary section 1842 against rotation in the first through hole 1110 may rotate this rotary section 1842 more stable and improve the rotational balance and stability of the microphone holder module. At the same time, since the damping assembly is added, the rotary section 1842 which is rotated relative to the first through hole 1110 may need to overcome the damping during rotation, which effectively prevents said rotary member from being accidentally rotated. On the other hand, when the user rotates the sound receiving unit 16 to the target position, it may no longer be necessary to fix the position of the sound receiving unit 16, thereby improving user convenience.

The material of the damping element 116 is not limited in any way within the scope of the present invention. In some embodiments, the implementation of the damping element 116 may be made of rubber, plastic, silicone, or other suitable material. In addition, the damping element 116 may also be made from other types of materials, such as a high damping alloy.

In some embodiments, as the sound receiving module 16 rotates, it may be desirable to increase the reliability of the rotation in addition to the stability relative to the rotation. If the sound module 16 can be rotated in the same direction without restriction (i.e., the range of rotation is greater than 360 degrees), the wire group, or other similar component, of the sound module 16 may be twisted or even broken. If the sound receiver module 16 can be rotated in the same direction without restriction, the damping assembly (damping groove 1843 and damping element 116) of the rotary member 184 may be more likely to be damaged, resulting in subsequent difficulty in adjusting the installation angle of the sound receiver module 16 by means of pivot element 184. Therefore, in some embodiments, it may be necessary to limit the range of rotation angles of the sound receiving module 16.

In some embodiments, connector assembly 18 may further comprise a rotation-limiting structure, where the rotation-limiting structure can be configured to limit the range of rotation angles of the rotation section 1842 relative to the first speaker housing section 111, thereby increasing the life of the rotation element.

In some embodiments, the rotation restricting structure may include a restrictive groove 18441 located in the upper portion of the rotary section 1842 in the circumferential direction, and a restrictive element 1116 located on the inner wall of the first through hole and consistent with the restrictive groove 18441. When the rotary section 1842 rotates about of the first section 111 of the loudspeaker housing, the restrictive member 1116 may abut against the two ends of the restrictive groove 18441 to prevent further rotation of said rotary section 1842.

As shown in FIG. 8 and FIG. 9, in some embodiments, the rotary section 1842 may be configured with a restrictive groove 18441. A convex block 11161 may protrude from the inner wall of the first through hole 1110 such that this convex block 11161 can be matched with the restrictive groove 18441 to limit the range of rotation angles of the rotary section. 1842.

In some embodiments, the rotation-limiting structure can be combined with a damping assembly (e.g., damping element 116 and damping groove 1843) and/or a first stop 18422 and a second stop 18423 in one or more of the above embodiments.

In some embodiments, said stop groove may be provided between the first stop stop 18422 and the second stop stop 18423 in the circumferential direction of the rotary main block 18421. The stop groove 18441 and the damping groove 1843 may be separated by some interval. In particular, the restrictive groove 18441 and the damping groove 1843 may be separated by some interval in the axial direction of the rotary main block 18421. For example, in the embodiment shown in FIG. 9, the stop groove 18441 may be closer to the first stop stop 18422 and the damping groove 1843 may be closer to the second stop stop 18423. In some embodiments, the stop groove 18441 may be in the form of an open loop. In other words, the angle occupied by the restrictive groove 18441 may be less than 360°. In some embodiments, the implementation of the angle occupied by the restrictive groove 18441 may be less than 300°. In some embodiments, the implementation of the angle occupied by the restrictive groove 18441 may be less than 270°. In some embodiments, the restrictive groove 18441 may coincide with the damping groove 1843. For example, the restrictive groove 18441 may dampen the rotation of the specified rotary element.

In some embodiments, the position of the restrictive groove 18441 and the convex block 11161 may not be limited in any way within the scope of the present invention. For example, the restrictive groove 18441 may be located on the inner wall of the first through hole 1110, and the convex block 11161 may be located on the rotary main block 18421.

In some embodiments, the implementation of the convex block 11161 may protrude from the inner wall of the first through hole 1110 (also shown in Fig. 9). This convex block 11161 can be inserted into the restrictive groove 18441. In this embodiment, when the rotary section 1842 rotates relative to the first section 111 of the loudspeaker housing, the two ends of the restrictive groove 18441 can change position relative to the convex block 11161 during rotation of the rotary section 1842. When the restrictive groove 18441 rotates to one end, against the specified convex block 11161, this convex block 11161 can limit further rotation of the specified rotary section 1842 in the current direction. In other words, the convex block 11161 may abut against the two ends of the restrictive groove 18441 to limit the range of rotation of said pivot section 1842.

The convex block 11161 located on the inner wall of the first through hole 1110 and the limit groove 18441 located on the rotary main block 18421 can limit the rotation angle range of said rotary section 1842, so that the sound receiving module 16 can only rotate within a certain range without unlimited rotation in one direction. Thus, the rotational reliability of the sound receiving unit 16 can be improved, the probability of the sound receiving unit 16 failing can be reduced, and the service life of the acoustic input and output device 10 can be extended.

In some embodiments, the implementation of the number of restrictive grooves 18441 and the number of convex blocks 11161 may be equal to one. More details regarding the matching of the restrictive groove 18441 and the convex block 11161 can be illustrated in one or more of the embodiments mentioned above, so they will not be illustrated here. In some embodiments, the number of restrictive grooves 18441 and the number of convex blocks 11161 may each be at least two. For example, the number of restrictive grooves 18441 and the number of convex blocks 11161 may each be two. Then two restrictive grooves 18441 may be located in the peripheral wall of the rotary section 1842 at some interval, and two convex blocks 11161 may be located on the inner wall of the first through hole 1110. One convex block 11161 may correspond to one restrictive groove 18441. In some embodiments, these two restrictive grooves 18441 may be located on the inner wall of the rotary section 1842 in the same plane or in different planes. In other words, the two restrictive grooves 18441 are offset from one another. The position of the convex block 11161 can be unrestricted as long as the convex block 11161 is matched and connected to the restrictive groove 18441.

In some embodiments, the rotation restricting structure may limit the range of rotation angles of said pivot member 184 in ways other than the restrictive groove 18441 and convex block 11161 used in one or more of the embodiments above. In some embodiments, the rotation-limiting structure may include a magnetic assembly (not shown in the drawing), such that the magnetic assembly may include a magnetic circuit located on the rotary section 1842 and extended in the circumferential direction, and a magnet located on the inner wall of the first through hole 1110 In some embodiments, this core can be of a certain length and surround the peripheral wall of the pivot section 1842. A strong bond between the magnets and the core can prevent the magnets from separating from the core. As the magnets tend to move toward the two ends of the core, the strong coupling between the magnets and the core can prevent the magnets from moving, thereby limiting the range of rotation angle of said pivot section 1842. In some embodiments, the length of the core may be less than the length of the peripheral wall of the pivot section 1842. Further, the length the magnetic circuit may be less than 5/6 of the circumference of the peripheral wall of the rotary section 1842, and the rotation angle range corresponding to the rotary section 1842 may be 300 degrees. Further, the length of the magnetic circuit may be less than 3/4 of the circumference of the peripheral wall of the rotary section 1842, and the rotation angle range corresponding to the rotary section 1842 may be 270 degrees.

In some embodiments, the implementation of the sound receiving module 16 and the rotary element 184 may be relatively fixed. In other words, the sound receiving module 16 may not be separable from the rotary element, for example, due to the presence of a bonding joint, a welded joint, or the like. However, in some practical application scenarios, it may often be necessary for the user to disassemble the sound receiving module for repair, replacement, or the like. If the connection between the sound receiver module and rotary member 184 is a fixed connection, it may be inconvenient to disassemble the sound receiver module 16. Therefore, in some embodiments, the sound receiver module 16 may be configured to be releasably connected to the rotary member 184. However, in some practical application scenarios, the position of the sound receiver module 16 may change frequently, so that the strength of the connection between sound receiving module 16 and rotary member 184 may be reduced after an extended period of time. Therefore, the sound receiving module 16 can be separated from the rotary member 184.

In some embodiments, the connection assembly 18 may further comprise an attachment assembly configured to restrict movement of the sound receiving module 16 relative to the pivot member 184. In some embodiments, the attachment assembly may be a detachable assembly. In some embodiments, the attachment assembly may include a third matching connector (not shown in the drawing) located on the section 1841 for passing wires, and a fourth matching connector located on the sound module 16, where this fourth connector (not shown in the drawing) matched and connected to the third matching connector. The matching between the third matching connector and the fourth matching connector may connect the sound receiver module 16 to the rotary element 184. In some embodiments, the third matching connector may be a coupling half located on the sound receiver module 16. The fourth matching coupling may be a notch for the coupling half , located on the first hollow segment 18410 of the section 1841 for passing wires and matched with the coupling half. The coupling half can be clamped in the coupling half notch to permanently connect the sound receiving module 16 to the pivot member 184.

It should be noted that the mount in the present invention can be combined with the connecting element 181 (for example, elastic element 1811) in one or more of the above options. For example, the connecting node 18 may contain the attachment point and the connecting element 181 at the same time. The sound receiving module 16 can be connected to the rotary element 184 through the connecting element 181, and the sound receiving module 16 can be connected to this connecting element 181 through the mount.

In accordance with FIG. 8 and FIG. 9, in some embodiments, in order to reduce the likelihood that the connecting element 181 inserted into the first hollow segment 11410 (for example, the elastic element 1811) will fall out or be pulled out of it, or another similar event, in some embodiments, the attachment assembly may contain a locking element 114, so that this locking element 114 can be located on the rotary element 184 for fixed connection of the specified connecting element 181 with the rotary element 184. In some embodiments, the implementation of the locking element 114 may be a part of the loudspeaker module 11, configured to lock the connecting element 181 inserted into the first hollow segment 11410, thereby restricting the movement of the microphone holder module (eg, the connector 181 and the sound receiving module 16).

In some embodiments, the locking element 114 may further comprise a permanently connected section located at one end of the locking main block 1141, and the first end of the connecting element 181 may be configured with an adaptive permanently connected section. The fixed connection section can be matched and connected to the adaptive fixed connection section.

In some embodiments, the adaptive permanently connected section may be a mounting hole 180. In particular, the mounting hole 180 may be located at the first end of the connecting element 181 inserted into the first hollow segment 11410.

In some embodiments, the permanently connected section may be a latch pin 1142, matched and connected to the mounting hole 180. In particular, the latch element 114 may include a latch main block 1141 and a latch pin 1142 located at one end of the latch main block 1141. block 1141 can be inserted into the second hollow segment 18420, and the latch pin 1142 can be inserted into the mounting hole 180 to restrict movement of the connecting element 181 and the sound module 16. In some embodiments, the latch main block 1141 can be configured with a hole 1140 for passing wires in the direction of length. When the locking element 114 is matched and connected to the rotary member 184, and this rotary member 184 is matched and connected to the first through hole 1110, the wire passage hole 1140 can communicate with the second hollow segment 18420 and the inner space 110 of the loudspeaker module 11, and the group of wires of the sound receiving module 16 can enter the wire passage hole 1140 through the first hollow segment 11410, and enter the inner space 110 by passing through the corresponding wire passage hole 1140 in the fixing main block 1141.

In some embodiments, the latch pin 1142 may be configured with a wire passage hole communicating with the wire passage hole 1140 in an axial direction (not shown). When the mounting hole 180 is matched and connected to the latch pin 1142, the group of wires of the sound pickup module 16 can enter the wire hole through the mounting hole 180 and enter the wire hole 1140 through the wire hole.

It should be noted that the specific design of the fixed connection section and the adaptive fixed connection section may not be limited in the present invention. In some embodiments, the permanently connected section may be a mounting hole 180 located at one end of the locking main block 1141, and this mounting hole 180 may communicate with the hole 1140 for passing wires. The adaptive permanently connected section may be a latch pin 1142 located at one end of the connecting element 181 (for example, the elastic element 1811), and the group of wires of the sound module 16 can enter the mounting hole 180 through the latch pin 1142, and enter the hole 1140 to pass wires through the mounting hole 180.

In some embodiments, the latch pin 1142 may include a sleeve. When the latch pin 1142 is matched and connected to the mounting hole 180, the sleeve can be clamped in the mounting hole 180 to prevent separation of the latch pin 1142 from the mounting hole 180, thereby further increasing the strength of the connection of the specified connecting element 181.

In some embodiments, the pivot section 1842 may need to have a certain stiffness to ensure that the pivot member 184 has sufficient bond strength when the pivot member 184 is coupled to the first speaker cabinet section 111. In some embodiments, when the pivot section 1842 is matched and connected to the first section 111 of the speaker cabinet, it may be necessary to insert the first stop 18422 and the pivot main block 18421 into the first through hole 1110. If the rigidity of the pivot section 1842 is too great, it may be inconvenient to insert the first stop 18422 and the rotary main block 18421 into the first through hole 1110. Therefore, it may be necessary that the rotary main block 18421 and the first stop 18422 have a certain elasticity. Based on the above reasons, the pivot section 1842 may need to be designed to have a certain resiliency for insertion into the first through hole 1110 while providing a certain rigidity.

In some embodiments, slots 18424 may be provided at one end of the pivot section 1842 far from the wire section 1841, and these slots 18424 may communicate with the second hollow segment 18420. locking main block 1141. These convex petals 1143 can be inserted into the slots 18424 to fill these slots 18424. The rotary main block 18421 can be stably placed in the second hollow segment 18420.

In some embodiments, the number of slots 18424 may be at least two, and these slots 18424 may divide one end of the rotary section 1842, far from the section 1841 for passing wires, into at least two sub-elements 18425, separated from one another by gaps in the direction around the circumference of the rotary section 1842. In other words, the slots 18424 can cut through the peripheral side of the rotary main block 18421, and in the circumferential direction of the rotary section 1842, one end of the rotary section 1842, remote from the section 1841 for the passage of wires, can be divided into the corresponding number of sub-elements 18425.

The end section of the rotary section 1842 may be divided into at least two sub-elements 18425 by slots 18424, so that one end of the rotary section 1842, remote from the section 1841 for passing wires, may have a certain elasticity. Difficulties in inserting the rotary section 1842 into the first through hole 1110 can be reduced and assembly efficiency can be increased. At the same time, the convex tabs 1143 can be inserted into the slots 18424 so that the structural integrity and strength of the pivot section 1842 can be improved by taking advantage of these two complementary approaches.

In some embodiments, the number of slots 18424 may be two, with the slots facing one another. The number of convex petals 1143 can be respectively equal to two, and in this case the petals are located one opposite the other. These two convex petals 1143 can be inserted into these two slots 18424, so that the locking element 114 can be located between the two sub-elements 18425 based on them. Further, said two convex tabs 1143 can be inserted into two slots 18424. Therefore, one end of the locking member 114 and one end of the pivot section 1842 farthest from the wire passage section 1841 can complement each other to form a complete annular structure.

In some embodiments of the present invention, the number of slots 18424 may be unlimited, such that the number of slots 18424 may be one, three, four, or more. The number of sub-elements 18425 may be the same as the number of slots 18424 so that the sub-elements 18425 may completely fill the slots 18424 to form a complete annular structure.

It should be noted that the description of the mount provided here is for convenience only, and one or more embodiments of the present invention may not be limited in the scope of the present description. It can be understood that specialists in the field under consideration, after understanding the principles of construction and operation of the mount, any combination can be implemented that does not deviate from the principles of the invention, or one or more of the nodes and modules described here can be excluded. For example, a permanently connected section and an adaptive permanently connected section may be excluded. For example, in one or more of the above embodiments, a combination of a mount with a wire mount is possible. As another example, in one or more of the above embodiments, a combination of an attachment assembly with an elastic element 1811 is possible. can be configured with an adaptive fixed section. The fixed connection section can be matched and connected to the adaptive fixed connection section to limit the movement of the elastic element 1811 relative to the pivot element 184. damping groove 1843) and a rotation-limiting structure (eg, restrictive groove 18441 and convex lobe 11161). All such modifications may be within the scope of one or more embodiments of the present invention.

In some embodiments, when the acoustic input and output device 10 is a bone conduction headset, the earhook assembly 12 may be included with and connected to the speaker module 11 such that the speaker module 11 can be in stable contact with the user's ears. to prevent the speaker module 11 from falling away from the user's ears.

In some embodiments, the number of temple nodes 12 may be at least one. For example, a bone conduction headset is a single ear headset. The number of loudspeaker modules 11 in the headset for one ear may be equal to one, and such one loudspeaker module 11 may be connected to one earpiece assembly 12 and attached to one of the user's ears. In some embodiments, the number of temple nodes may be two. For example, a bone conduction headset may be a two-ear headset. When a user wears a bone conduction headset, two groups of speaker modules 11 can be connected to two groups of earpiece assemblies 12 and attached near the user's left and right ears to realize dual-ear operation.

In some embodiments, the second through hole 1111 in the first section 111 of the loudspeaker housing can be configured to match and mate with the earpiece assembly 12, and the group of wires of the sound receiver module 16 can pass through the earhook assembly 12 and enter the containing space 120 through the second through hole 1111. The following is an example of a description of the temple node 12 in this embodiment.

In some embodiments, the temple assembly 12 may include a temple connector and a temple housing. This temple connector 122 may be connected to the second through hole 1111 and the temple body. The interior of the temple housing may be configured to include a housing space 120 to accommodate at least one of the battery module 14 and/or the control circuit module 15. The group of wires of the sound receiving module 16 may pass through the second through hole 1111, enter the containing space 120 through the earhook connector 122, and be electrically connected to the battery module 14 and/or to the control circuit module 15 in the containing space 120.

As shown in FIG. 10 and FIG. 11, in some embodiments, the temple housing may comprise a first temple housing section 121 and a second temple housing section 123 matched with the first temple housing section 121. When the first section 121 of the temple body is matched and connected to the second section 123 of the temple body, the temple body can be created, and an accommodating space 120 can be formed within each temple body. installation of the battery module 14, as in the temple assembly 12 shown in FIG. 10. The accommodation space 120 in the other temple assembly 12 may be configured to receive a drive circuit module 15, as in the temple assembly 12 shown in FIG. 11. In some embodiments, housing space 120 in temple assembly 12 may contain control circuitry and battery module 14 installed within module 15 at the same time.

In some embodiments, the implementation of the node 12 of the temple may include a connecting node 122 of the temple. One end of the temple connector 122 may be connected to the first section 121 of the temple housing. The other end of the connecting node 122 of the temple can be connected to the module 11 of the speaker. For example, in the embodiment shown in FIG. 10, the other end of the earhook connector 122 can be inserted into the second through hole 1111 of the first speaker body section 111 to be matched and inserted into the speaker module 11.

In some embodiments, the other end of the earhook connector 122 may be connected to the speaker module 11 in other ways. For example, the temple connector 122 may further comprise a temple matching connector. This matching earhook connector may be connected to the second through hole 1111 and to the other end of the earhook connector 122. An example of such a temple matching connector would be a matching connector tube. The other end of the temple connector 122 and the second through hole 1111 may be connected to the two ends of the matching connector tube, respectively, to realize the connection between the temple connector 122 and the second through hole 1111.

As shown in FIG. 10, in some embodiments, battery module 14 may include a battery case and a battery management integrated circuit (chip) located in the battery case (not shown). The battery management IC can be configured to conserve power. The first NFC module 102 mentioned in the headset communication system embodiments may be attached to the battery module 14 in one or more embodiments. For example, the first NFC unit can be attached to the battery case, so that the volume of the acoustic input and output device 10 can be reduced, and electromagnetic interference or signal interference between the first NFC unit 102 and the control circuit unit 15 can also be reduced.

As shown in FIG. 11, in some embodiments, the control circuit module 15 may include a printed circuit board 151, a power supply interface 152, a button 153, an antenna 154, or other similar components. As shown in FIG. 2, in some embodiments, the first Bluetooth module 101 may be integrated into the control circuit module 15. The control circuit module 15 may also integrate other circuits and elements. For example, the first Bluetooth module 101 may be integrated on the printed circuit board 151. For example, the sensor module 17 may also be integrated on the printed circuit board 151.

As shown in FIG. 11, if, as an example, the sensor module 17 comprises an optical sensor, in the present invention, the first earpiece body section 121 may form a window 1200 for transmitting optical signals of the optical sensor. This window 1200 may be located adjacent to the temple connector 122, for example, as shown in FIG. 11, this window 1200 can be located near the junction between the first earpiece body section 121 and the earhist connector 122, so that when the user is wearing the acoustic input and output device 10, the window 1200 can be attached and located close to the position near the root of the user's ear. In some embodiments, the shape of the window 1200 may be circular, elliptical, rectangular, rectangular-like (eg, the four corners of the rectangle are rounded), polygonal, or other similar shape. In some embodiments, the shape of the window 1200 may be similar to a rectangular one. For example, as shown in FIG. 11, in some embodiments, window 1200 may be defined in the form of a racing circle. In some embodiments, the extension of the central axis of the temple connector 122 and the long axis of the window 1200 may intersect with each other, for example, as roughly shown in FIG. 11. Such an intersection of the extension of the central axis of the temple connector 122 and the long axis of the window 1200 with one another can effectively make the window 1200 attached and close to the position near the root of the user's ear. This can guarantee the sensitivity and validity of the data received by the sensor module 17 . In some embodiments, the first temple housing section 121 of the temple assembly 12, configured to be installed within the control circuit module 15, may form the window 1200 mentioned above.

In some embodiments, the first temple housing section 121 may need to be matched and connected to the second temple housing section 123 to form a complete temple housing. In some embodiments, the first section 121 of the temple body may be connected to the second section 123 of the temple body directly, for example, by means of a bonded joint, welded joint, riveted joint, or other similar joint. In some embodiments, the first section 121 of the temple housing may be connected to the second section 123 of the temple housing through a mechanical structure, such as a snap-on structure, a pin structure, or other similar structure.

In some application scenarios, the design trends of the acoustic input and output device 10 may be towards lightweight and miniaturization of the device, while the earhook assembly 12, configured to accommodate a battery module 14, a control circuit module 15, associated wires, or other similar components, may be part of an acoustic device 10 input and output of a larger volume. At the same time, the position of the associated coupling halves and the design of the coupling halves of the temple assembly 12 may affect the volume of the entire temple assembly 12. To reduce the bulk of the temple assembly 12, in some embodiments, the temple assembly 12 may include a docking station configured to restrict movement of the first temple body section 121 and the second temple body section 123 in the docking direction and in the thickness direction. The docking station described in this embodiment can reduce the volume of the temple assembly 12 by providing a strong connection between the first temple body section 121 and the second temple body section 123. The following describes the design of the housing and docking station for the node 12 of the temple, proposed in this embodiment.

In some embodiments, the docking station may include a first docking element and a second docking element, consistent with the first docking element. These first docking element and the second docking element can be located on the first section 121 of the body of the temple and the second section 123 of the body of the temple, respectively. When the first docking member is matched and connected to the second docking member, the first temple body section 121 and the second temple body section 123 can be relatively fixed in the docking direction and in the thickness direction. In some embodiments, the first docking member may include a first groove 1211 and a second groove 1212 extending in the length direction of the first temple body section 121 and opening in the same direction. The second docking element may include a first block 1231 and a second block 1232 protruding in the length direction of the second section of the temple body and extended in the same direction, so that the first block 1231 and the second block 1232 can be inserted into the first groove 1211 and into the second groove 1212, respectively, in the same direction.

In particular, the first section 121 of the temple body may be configured with the first groove 1211 and the second groove 1212 spaced apart. The second section 123 of the temple body may be configured with the first block 1231 and the second block 1232 spaced apart. The first groove 1211 can be matched and tightly connected to the first block 1231, and the second groove 1212 can be matched and tightly connected to the second block 1232. Therefore, the first section 121 of the temple body can be matched and tightly connected to the second section of the temple body.

For convenience in describing the docking station and the details of the docking between the first section 121 of the temple body and the second section 123 of the temple body, in some embodiments, the containing space 120 may have a length direction perpendicular to the thickness direction. In the present invention, unless specifically indicated otherwise, the length direction may indicate the length direction of the containing space 120 (as shown in Fig. 13), the thickness direction may indicate the thickness direction of the containing space 120 (as shown in Fig. 13), and the docking direction may indicate the direction of movement when the first temple body section 121 and the second temple body section 123 are docked, as shown in FIG. 14. As shown in FIG. 12 and FIG. 13, in some embodiments, the first temple body section 121 and the second temple body section 123 may be joined in a mating direction perpendicular to the length direction and thickness direction to form an accommodating space 120. For example, the first temple body section 121 may comprise a first accommodating subspace 1210, and the second temple body section 123 may comprise a second containing subspace 1230. After the first temple body section 121 and the second temple body section are joined, the first containing subspace 1210 and the second containing subspace 1230 may be combined to form the containing space 120.

In some embodiments, the first section 121 of the temple body may be configured with the first groove 1211 and the second groove 1212 spaced apart in the length direction and opening in the same or similar directions. For example, the first groove 1211 and the second groove 1212 may open in the same direction. The second section 123 of the temple body may be configured with the first block 1231 and the second block 1232 projecting in the length direction and extending in the same or similar directions. For example, the first block 1231 and the second block 1232 may be spaced apart in the length direction, and the direction in which the first block 1231 and the second block 1232 project may be the same so that the blocks face the same direction. . When the first temple body section 121 and the second temple body section 123 are mated, the first block 1231 and the second block 1232 are inserted into the first groove 1211 and the second groove 1212, respectively, in the same direction. As shown in FIG. 14, the first block 1231 may be inserted into the first groove 1211, and the second block 1232 may be inserted into the second groove 1212 to limit relative movement of the first temple body section 121 and the second temple body section 123 in the joint direction and in the thickness direction.

In some embodiments, the first mating edge 1201 of the first temple housing section 121 and the second mating edge 1202 of the second temple housing section 123 may be aligned with each other to limit the relative movement of the first temple housing section 121 and the second temple housing section 123 in the length direction. The first mating edge 1201 of the first temple housing section 121 may be the edge of the first temple housing section 121 facing one side of the second temple housing section 123 and mating with the second temple housing section 123, such as the first mating edge 1201 shown in FIG. 12. The second mating edge 1202 of the second temple housing section 123 may be the edge of the second temple housing section 123 facing one side of the first temple housing section 121 and mating with the first temple housing section 121, such as the second mating edge 1202 shown in FIG. 13. The fact that the first section 121 of the temple body and the second section 123 of the temple body are matched with one another may mean that the shapes of the first mating edge 1201 of the first section 121 of the temple body and the second mating edge 1202 of the second section 123 of the temple body can be matched with each other. the other, so that they can be connected to one another or complement each other, forming a stable coordinated structure and limiting relative movement in the direction of length. In this embodiment, the fact that the first section 121 of the temple body and the second section 123 of the temple body are mated may mean that the first mating edge 1201 of the first section 121 of the temple body can essentially be in contact with and connected to the second mating edge 1202 of the second section 123 of the temple temple.

In some embodiments, the directions of extension of the first block 1231 and the second block 1232 may be opposite. In other words, the first block 1231 and the second block 1232 may protrude in different directions, respectively. For example, the first block 1231 may protrude to the left in the length direction, and the second block 1232 may protrude to the right in the length direction. Accordingly, the directions where the first groove 1211 and the second groove 1212 open may also be opposite. However, when the extension directions of the first block 1231 and the second block 1232 are opposite, the first block 1231 and the second block 1232 may protrude in opposite directions, which inevitably increases the additional space occupied by the first block 1231 and the second block 1232. In particular, in order to to ensure that the first block 1231 and the second block 1232 are inserted into the first groove 1211 and the second groove 1212, it may be necessary to increase the distance in the length direction to enclose the first block 1231 and the second block 1232, in other words, the temple body size may be increased. In this embodiment, since the first groove 1211 and the second groove 1212 open in the same or similar directions, and the first block 1231 and the second block 1232 protrude in the same or similar directions, the matching directions of the first block 1231 and the second block 1232, with the first groove 1211 and the second groove 1212 will be the same. Further, since the extension directions of the first block 1231 and the second block 1232 are the same or similar, the additional volumes of the first block 1231 and the second block 1232 can be reduced, and the volume occupied by the matching between the first block 1231 and the second block 1232, and the first groove 1211 and the second groove 1212 can also be reduced, which effectively reduces the volume of the temple assembly 12. In addition, since the mating edge 1201 of the first section 121 of the temple body is aligned with the second mating edge 1202 of the second section 123 of the temple body, so it may not be necessary to use additional coupling halves, protrusions, or the like, so that the temple assembly 12 will be more compact. and the volume of this temple node 12 will be less. At the same time, the matching of the first block 1231 and the second block 1232, and the first groove 1211 and the second groove 1212 can limit the movement of the first temple body section 121 and the second temple body section 123 in the joint direction and in the thickness direction. The displacement in the length direction can be limited as a result of the matching between the first mating edge 1201 and the second mating edge 1202, so that the mating of the first temple body section 121 and the second temple body section 123 can be more stable and the structure can be more reliable.

As shown in FIG. 12, in some embodiments, the first groove 1211 and the second groove 1212 may be located on two sides of the first temple body section 121 in the length direction, respectively. The direction where the first groove 1211 opens may face the containing space 120, and the direction where the second groove 1212 opens may deviate from the containing space 120. In other words, the direction where the first groove 1211 opens may face the first containing subspace. 1210, and the direction in which the second groove 1212 opens may deviate from the first enclosing subspace 1210. In some embodiments, the first groove 1211 may be located on one side of the first temple body section 121 near the temple connector 122, and the second groove 1212 may be located on one side of the first section 121 of the body of the temple, remote from the connecting node 122 of the temple.

As shown in FIG. 13, in some embodiments, the first block 1231 and the second block 1232 may be located on two sides of the second section 123 of the temple body in the length direction, the direction of extension of the first block 1231 may deviate from the containing space 120, and the direction of extension of the second block 1232 may be reversed in enclosing space 120. In other words, the direction of extent of the first block 1231 may deviate from the second enclosing subspace 1230, and the direction of extent of the second block 1232 may face the second enclosing subspace 1230. Accordingly, the first block 1231 may be located on one side of the second housing section 123 temple near the temple connector 122, and the second block 1232 may be located on one side of the second section 123 of the temple body, remote from the temple connector 122. Since the second block 1232 protrudes and extends into the containing space 120, compared to protruding and extending outward from the containing space 120, it may not be necessary to occupy additional space, so that the corresponding space can be saved. The second groove 1212 may be positioned forward in the extension direction of the second block 1232 when the second block 1232 is aligned with the second groove 1212. Having the second block 1232 aligned and inserted into the second groove 1212 may reduce the volume of the temple assembly 12.

It should be noted that the positions where the first groove 1211, the second groove 1212, the first block 1231 and the second block 1232 are located, and the specific shapes of these elements may not be specifically limited in the present invention. For example, the extension directions of the first block 1231 and the second block 1232 may be oriented to the right in the length direction, respectively, and the directions of insertion into the first groove 1211 and the second groove 1212 may correspond to the directions noted above. Such shape changes may be all within the scope of the present invention.

In some embodiments, when the first block 1231 and the second block 1232 are matched and connected to the first groove 1211 and the second groove 1212, respectively, since the directions of extension of the first block 1231 and the second block 1232 are the same or similar, for one section of the temple body (for example, second section 123 of the temple body), only the movement in the direction of extension of the first block 1231 and the second block 1232 can be limited. For example, in the embodiments shown in FIG. 14, the first block 1231 and the second block 1232 may be extended to the left in the length direction. When the first temple body section 121 is matched and connected to the second temple body section 123, this second temple body section 123 cannot move to the left in the length direction relative to the first temple body section 121. However, the second section 123 of the temple body can move to the right in the length direction. Therefore, the relative movement of the first temple body section 121 and the second temple body section 123 may not be completely limited based on the matching between the block and the groove.

In some embodiments, the implementation of the first docking element may further contain the first blocking section 1213, located on the first docking edge 1201 of the first section 121 of the temple body. The second docking element may further include a second blocking section 1234 located on the second docking edge 1202 of the second section 123 of the temple body. The first blocking section 1213 can be matched with the second blocking section 1234 to limit the relative movement of the first section 121 of the temple body and the second section 123 of the temple body in the length direction. That the first interlocking portion 1213 and the second interlocking portion 1234 are matched with one another may mean that the shape of the first interlocking portion 1213 and the shape of the second interlocking portion 1234 are matched with one another. The first blocking section 1213 and the second blocking section 1234 can be matched or complementary to each other, forming a stable mating structure to limit the relative movement of the first section 121 of the temple body and the second section 123 of the temple body in the length direction. For example, the first blocking section 1213 may be a hole created in the first mating edge 1201 of the first section 121 of the temple body, and the second blocking section 1234 may be a raised section created on the second mating edge 1202 of the second section 123 of the temple body. The shape of the hole and the shape of the convex portion can be matched with each other, so that the first mating edge 1201 of the first section 121 of the temple body and the second mating edge 1202 of the second section 123 of the temple body can be complementary to one another to limit relative movement in the length direction. In some embodiments, the opening may be a notch that forms a socket, and the raised portion may be a protrusion that is consistent with this notch-socket. The convex portion can be matched with the notch-socket to limit the relative movement of the first section 121 of the temple body and the second section 123 of the temple body in the direction of the length.

It should be noted that the present invention may not specifically limit the specific structure and arrangement of the first blocking portion 1213 and the second blocking portion 1234. For convenience of description, one or more embodiments of the present invention may not be limited only by the scope of the above embodiments. It can be understood that a person skilled in the art, after understanding the principles of construction of the first blocking section 1213 and the second blocking section 1234, can make improvements without deviating from the principles of the present invention. For example, the first blocking portion 1213 may be a raised portion formed on the first mating edge 1201 of the first temple body section 121, and the second blocking portion 1234 may be a groove opening created on the second mating edge 1202 of the second temple body section 123.

In one or more embodiments, the direction of the opening into which the first groove 1211 opens may face the enclosing space 120. the first groove 1211 may intersect and interfere with each other when the respective molds are used to form the first enclosing subspace 1210 and the first groove 1211. other structures, this can create great difficulties in production. Therefore, embodiments of the invention provide the following structure to reduce production difficulties.

As shown in FIG. 15, in some embodiments, the first temple body section 121 may be configured with a hollow segment 1215 on the outside and a hollow segment 1216 on the inside communicating with each other in a direction from the outside of the containing space 120 to the inside of that containing space 120. In other words, the direction where the outer side hollow segment 1215 opens may face away from the containing space 120, and the direction where the inner side hollow segment 1216 opens may face into the containing space 120. The outer side hollow segment 1215 may communicate with the inner side hollow segment 1216. In some embodiments, the shapes of the openings that open the inner side hollow segment 1216 and the outer side hollow segment 1215 may be a rectangle, triangle, circle, or other similar side, which is not specifically defined in this application.

In some embodiments, the outer side hollow segment 1215 may be filled with an infill element 1217. The infill element 1217 may be, without limitation, a plastic element, a metal element, a rubber element, or the like. For example, the filling element may be made of a hard adhesive. When the outer side hollow segment 1215 is filled and locked, the inner side hollow segment 1216 may be configured as the first groove 1211, and the direction in which the inner side hollow segment 1216 opens may face the containing space 120 to match the first block 1231.

In an actual process, the outer side hollow segment 1215 and the inner side hollow segment 1216 may be formed in turn, starting from the outer side of the first temple body section 121 and then proceeding to the inside of the first temple body section 121. Since the drawing direction of the pattern of the outer side hollow segment 1215 and the inner side hollow segment 1216 is not necessarily in the first enclosing subspace 1210, and this drawing is outside the first temple body section 121, the outer side hollow segment 1215 can be filled with a filling element 1217 to allow the use of the rest of the inner-side hollow segment 1216 as the first groove 1211, manufacturing complexity and difficulty can be effectively reduced and costs saved.

In some embodiments, the cross-sectional area of the hollow segment 1215 of the outer side perpendicular to the direction of connection of the hollow segment 1215 of the outer side and the hollow segment 1216 of the inner side may be greater than the cross-sectional area of the hollow segment 1216 of the inner side perpendicular to the direction of connection of the hollow segment 1215 of the outer side and the hollow segment 1216 of the inner side sides. Since the cross-sectional area of the corresponding outer side hollow segment 1215 is larger than the corresponding cross-sectional area of the inner side hollow segment 1216, it may be convenient to fill the outer side hollow segment 1215 with the filling element 1217, thereby improving the blocking effect and quickly creating the first groove 1211.

Below is an example of a description of the method of manufacturing the node 12 of the temple according to the considered option:

Step S100: The first temple body section 121 and the second temple body section 123 can be formed by injection molding, and the outer side hollow segment 1215 and the inner side hollow segment 1216 communicating with each other can be formed in the first shell section 121 temple in the direction from the outer side of the first section 121 of the body of the temple into the first section 121 of the body of the temple; a first block 1231 may be formed on the second section 123 of the temple body.

Step S200: The outer side hollow segment 1215 can be filled with the filling element 1217 and the inner side hollow segment 1216 can be used as the first groove 1211.

Alternatively, the hollow segment 1215 of the outer side can be filled with filling element 1217 using injection molding.

In some embodiments, to protect the first temple body section 121, this first temple body section 121 may be covered with the temple elastic cover layer 1223 after step S200, the details are as follows:

Step S210: the periphery of the first section 121 of the temple body can be coated with the elastic casing layer 1223 of the temple by injection molding, and the hollow segment 1215 of the outer side can also be coated.

The elastic cover layer 1223 of the temple may be part of the assembly 12 of the temple in contact with the user. The surface of the earpiece assembly 12 configured with the earhook elastic cover layer 1223 can improve the comfort degree for the user when wearing the bone conduction headset and improve the comfort and feel for the user. Additional details regarding the elastic cover layer 1223 temples can be given in the description of other embodiments of the present invention, so they may not be described here.

Step S300: The first groove 1211 may be matched with the first block 1231 and the block may be inserted into and filled in the groove to mate the first earpiece body section 121 and the second earpiece body section 123.

Other structures in the temple assembly 12 may be manufactured using an existing injection molding process based on the specific structure of the temple assembly 12 described above, so it may not be described here.

In some embodiments, the accommodating space 120 of the earhook assembly 12 may receive other bone conduction headset components, such as a battery module 14, a control circuit module 15, or other similar components. To assist the user in controlling the headset using bone conduction, a button structure associated with said components may also be located on the temple housing. For example, the temple housing may be configured with a power plug hole 1233 that is electrically connected through the holes to the battery module 14 so that a user can charge the battery module 14 through the power plug hole 1233. As another example, the button hole 1235 located on the temple body may be electrically connected to the control circuit module 15, and the control button located in the button hole 1235 may be electrically connected to the control circuit module 15, for example, this may be volume button, pause/start button. The user can control the headset using bone conduction through the control button.

In order to further reduce the volume of the temple assembly 12, the positions of the components of the containing space 120 can be designed to effectively compress the containing space 120 and reduce the volume of the temple body section.

In some embodiments, if the hole 1233 for the power plug, or other similar hole, in the acoustic input and output device 10 can be located on one side of the second section 123 of the temple body, remote from the bottom wall 1112 of the first section 121 of the temple body, the volume of the node 12 the temple can be enlarged. To effectively reduce the volume of the temple assembly 12, the position of the power plug hole 1233 may be appropriately selected in one or more embodiments of the present invention, the details are given below:

As shown in FIG. 12 - Fig. 14, in some embodiments, the temple housing may include a user-facing body panel, a back panel of the body away from the user, and a plurality of side panels connecting the body panel and back of the body. The button hole 1235 and the power plug hole 1233 may be located on different side panels of the case from a plurality of side panels of the case, respectively.

In some embodiments, the temple body may have various shapes, for example, the temple body may be spheroid, elliptical spheroid, rectangular cuboid (e.g., 8 corners of rectangular squares are rounded corners), prismatic body, or other similar shape. In some embodiments, when the first temple body section 121 and the second temple body section 123 are joined, a shape as shown in FIG. 14.

In some embodiments, the portion (eg, case side panels below the docking direction shown in FIG. 14) of the second temple body section 123 remote from the temple connector 122 may be configured with a power plug hole 1233. The power plug hole 1233 may communicate with the containing space 120, and the power plug hole 1233 can be configured to house the power supply interface 152. The battery module 14 can be charged via the power interface. In some embodiments, the second temple housing section 123 may comprise a lower housing and a side housing, and the side housing may surround and connect the lower housing to the second enclosing subspace 1230. The lower housing may be understood to mean the side panels of the housing below the mating direction shown in FIG. 14. The side of the body may be part of the side panels of the body (eg, part of the body panels in the docking direction) of the temple. The side edge of the side of the body, remote from the bottom of the body, may be a second mating edge 1202, docked with the first section 121 of the body of the temple.

In some embodiments, button hole 1235 and power plug hole 1233 may be located on different side panels of the case. Under the different side panels of the case, as described here, you can understand the side panels of the case, extending in different directions. For example, in the embodiment shown in FIG. 14, the button hole 1235 and the power plug hole 1233 can be located on the side panels of the case (for example, in the bottom of the case) below the docking direction and on the side panels of the case (for example, in the side of the case) with the longitudinal directions turned to the right, respectively.

In some embodiments, the power plug hole 1233 may be located on the side of the housing and communicate with the second containing subspace 1230, in other words, communicate with the containing space 120.

As shown in FIG. 14, in some embodiments, the second block 1232 may be located adjacent to the power plug hole 1233. In other words, the second block 1232 may protrude from the part of the second section 123 of the temple body farthest from the connecting node 122 of the temple, and be extended towards the interior of the containing space 120. In this embodiment, the second block 1232 may be located closer to the containing space 120 compared to hole 1233 for the power plug, in other words, the second block 1232 may be closer to the connecting node 122 of the temple than the hole 1233 for the power plug.

In some embodiments, the projections of the second block 1232 and the power plug hole 1233 onto the first reference plane perpendicular to the length direction may overlap. In this embodiment, such an overlay can be a partial overlap (for example, the overlay of part of the projection of the second block 1232 on the part of the projection of the hole 1233 for the power plug), or a complete overlay (for example, the projection of the second block 123 falls completely on the projection of the hole 1233 for the power plug) . In this embodiment, taking a plane perpendicular to the length direction as the first reference plane, the projection of the second block 1232 on the first reference plane can be located in the projection of the plane 1233 of the power plug on the first reference plane, in other words, the areas of the two projections can completely overlap one another. Such positions of the second block 1232 and the power plug hole 1233 can make the design of the second section of the temple body 123 compact, so that the volume of the temple body 12 can be reduced without affecting the installation of the power supply interface 152.

In some embodiments, the projections of the second block 1232 and the power plug hole 1233 on the second reference plane perpendicular to the mating direction may overlap. The overlay described here can also be a partial overlay or a full overlay. In this embodiment, taking the plane perpendicular to the mating direction as the second reference plane, the projection of the second block 1232 on the second reference plane may also be located on the projection of the power plug hole 1233 on the second reference plane, in other words, the areas of the two projections may also overlap one to the other. The arrangement of the structures of the second block 1232 and the power plug hole 1233 can be compact regardless of the mating direction or the length direction. The space occupied by the power plug hole 1233 and the second unit 1232 can be saved to increase the degree of compactness of the temple assembly 12.

It should be noted that the present application may not specifically limit the positions of the power plug hole 1233 and the button hole 1235. For example, in addition to the positions of these components described in the embodiments above, the power plug hole 1233 may be located on the side panels of the earhook housing above the docking direction, and the button hole 1235 may be located on the side panels of the housing below the docking direction. As another example, the power plug hole 1233 may be located on the side panels of the earhook housing below the docking direction, and the button hole 1235 may be located on the side panels of the housing on the left side in the length direction.

In some embodiments, in addition to the side panels of the case, the button hole 1235 or the power plug hole 1233 may also be located on the back of the case. For example, button hole 1235 and power plug hole 1233 may be located on the side panels of the case and on the back of the case, respectively. In particular, the button hole 1235 may be located on the side panels of the case below the docking direction, and the power plug hole 1233 may be located on the back of the case.

The acoustic input and output device 10 can be used in industry, so that there may be large requirements for controlling the operation of the acoustic input and output device 10. Positioning the power plug hole 1233 and the button hole 1235 in different positions can improve the usability of the acoustic input and output device 10, and there may be the following reasons for this.

In some embodiments, the acoustic input and output device 10 may typically have a volume button 153 or the like. The hole 1235 for a button or the like and the hole 1233 for the power plug corresponding to the button 153 may be generally located at the bottom of the second section 123 of the temple body, in other words, the second section 123 of the temple body may be removed from part of the first section 121 temple shells. Since the area of the bottom of the case is relatively limited, the button hole 1235 and the power plug hole 1233 can be compact. The button hole 1235 and the power plug hole 1233 can take up as little space as possible. In some scenarios, the wearer may have work clothes, gloves, and the like. The button hole 1235 may be smaller and the arrangement may be too compact, which may make operation by the wearer less convenient and may easily lead to operating errors. The power plug hole 1233 in one embodiment may not be located at the bottom of the case, and the power plug hole 1233 may be located on the side of the case so that the button hole 1235 can be made larger and its location can be more fluent, which can be more user-friendly and reduce the possibility of control errors.

In some embodiments, if the second block 1232 is located close to the power plug hole 1233 on the second temple body section 123 and faces the top position of the first temple body section 121 (such as the region of the plane connecting the second block 1232, in other words, the second block 1232 may be considered to protrude upward from the plane region in the direction of mating), the space of the insertion hole 1218 (as shown in Fig. 18) in the first section 121 of the temple body may be compressed, which in turn may affect the matching and mating of the temple assembly 12 with other nodes (with rear holder 13) headset using bone conduction. The second block 1232 may need to take up additional space such that the first temple body section 121 and the second temple body section 123 may take up a large space in the docking direction, which may not be compact enough. Therefore, in one or more embodiments of the present invention, the second block 1232 and the power plug hole 1233 may be located in the lower part of the second section 123 of the temple body, and the structure between the second block 1232 and the power plug hole 1233 can be built based on the above higher projection ratios, so that the structure of the second section 123 of the temple body can be more compact in the docking direction. The second block 1232 can protrude into the housing space 120 and the size of the earhook body 12 can be miniaturized without taking up additional space.

In order to reduce the failure rate of the acoustic input and output device 10, it may be necessary not only to ensure structural stability, but also to ensure electrical connection stability. A group of wires (for example, a group of wires of the sound receiver module 16 and a group of wires of the loudspeaker module) can be routed between the sound module 16, the speaker module 11 and the earpiece assembly 12, the stability of the wiring can be related to the reliability of the headset using bone conduction. To improve wire routing reliability, in some embodiments, the earhook connector 122 may include a earhook connector and a wire clip. The earhook connector may be configured with a lead channel configured to conduct a group of wires from the loudspeaker module 11. The wire clamp may be configured to clamp and lock the wire bundle in the radial direction of the wire bundle, thereby improving the reliability of the bone conduction headset.

In some embodiments, the connector section 1222 may be located at one end of the temple connector remote from the temple body. As shown in FIG. 15 and FIG. 16, in some embodiments, a plurality of wire clips may include a first wire clip 1224 and a second wire clip 1219. The first wire clip 1224 may be located in the connecting section 1222, and the second wire clip 1219 can be located in the first section 121 of the earhook body. The group of wires leading from the speaker module 11 can enter the containing space 120 through the first wire clip 1224 and the second wire clip 1219 in series. The first wire clamp 1224 and the second wire clamp 1219 may be configured to clamp and lock the wire group in the radial direction of the wire group so that radial jarring of the wire group can be reduced.

In some embodiments, the group of wires clamped and locked by the first wire clip 1224 and the second wire clip 1219 may be an additional element, such as an auxiliary titanium wire used in the manufacture of the temple assembly 12, or another similar element. In particular, in the manufacture of the temple assembly 12, a leading channel can be formed in the elastic covering layer 1223 of the temple using an auxiliary titanium wire. Therefore, the auxiliary titanium wire can pass sequentially through the first wire clip 1224 and the second wire clip 1219 and enter the containing space 120. After the fabrication is completed, the auxiliary titanium wire can be pulled out of the leading channel of the inner space 110 and the containing space 120. The first clip 1224 wire clamp and the second wire clamp 1219 can keep the stability of the auxiliary titanium wire to reduce the shaking of the auxiliary titanium wire, which can form the leading channel to meet the quality requirements and improve the yield.

In some embodiments, the implementation of the leading channel (not shown in the drawing) and the elastic metal thread of the temple can run in parallel in the elastic cover layer 1223 of the temple.

In some embodiments, the wire group clamped and locked by the first wire clamp 1224 and the second wire clip 1219 may be a wire group (e.g., a sound pickup module wire group) used for electrical connection and routed after the lead path has been created. In other words, the group of wires conducted by the loudspeaker module 11 may enter the containing space 120 through the first wire clamp 1224 and the second wire clamp 1219 and electrically connect to components (e.g., battery module 14 and control circuit module 15) in the containing space. 120. It should be understood that the jarring of the wire bundle may need to be reduced before it is introduced into the leading channel and after it is inserted into the leading channel, in order to increase the efficiency of the wire routing. In addition, since the temple assembly 12 is used to hang the device on a person's ear, the temple assembly 12 may have a generally arcuate shape. Since the wire group passing through the earpiece assembly 12 may be subject to shaking, misalignment, and the like, the first wire clip 1224 and the second wire clip 1219 can reduce the shaking of the wire group.

It should be noted that the wire clamp may be used in one or more of the above embodiments. For example, if the speaker module 11 is also connected to the clamping component (for example, the connector 181 and the sound receiving module 16), the wire group conducted by the speaker module 11 may comprise the speaker wire group 113 and the sound receiver module 16 wire group. If the speaker module 11 is not connected with the microphone holder module, the group of wires conducted by the loudspeaker module 11 may contain the group of loudspeaker wires 113.

In this embodiment, the first wire clip 1224 and the second wire clip 1219 may be located in the connection section 1222, respectively. On the one hand, the movement of the auxiliary titanium wire relative to the first section 121 of the temple body and the connecting section 1222 can be clamped during manufacture to increase the yield of the temple assemblies 12, on the other hand, the movement of the wire group in the radial direction can also be clamped by the clamps, thereby reducing the shaking of this group of wires, so that the routing efficiency of this group of wires can be improved. The structure of the wire group in the actual product can be more stable, so that the stability of the electrical connection can be guaranteed.

In some embodiments, the first wire clamp 1224 may have two first wire clamp sections 12241 located in the thickness direction. As shown in FIG. 16, these two first wire clamp sections 12241 can be offset from one another in the length direction of the wire group. These two first wire clamp sections 12241 can clamp and lock the wire group in the thickness direction when the wire group passes between the two first wire clamp sections 12241, which in turn can restrict movement of the wire group in the thickness direction.

In some embodiments, the lengths of the first two wire clamp sections 12241 may differ in the length direction of the wire group. For example, the length of the first wire clip 1224 close to the second wire clip 1219, in the wire group length direction, may be greater than the length of the first wire clip 1224 farthest from the second wire clip 1219, in the wire group length direction.

The second wire clamp 1219 may have two second wire clamp sections 12191 arranged in the thickness direction, and the two second wire clamp sections 12191 may be positioned opposite each other. These two second wire clamp sections 12191 can clamp and lock the wire group in the thickness direction as the wire group passes between the two second wire clamp sections 12191, which in turn can restrict movement in the thickness direction.

It should be noted that the number of the first wire clamp sections 12241 and the number of the second wire clamp sections 12191 may not be limited in the present invention, for example, the number of the first wire clamp sections 12241 and the number of the second wire clamp sections 12191 may be one, three , four or another similar value.

In some embodiments, the first wire clip 1224 may be formed in a recess in the connecting section 1222 and the second wire clip 1219 may be formed in a recess in the first section 121 of the temple body so that the group of wires can be seen in the first wire clip 1224 and in the second wire clamp 1219, which can reduce the distance the wire group travels through the invisible area and improve the wiring efficiency. In some embodiments, the first wire clip 1224 and the second wire clip 1219 may be hollow structures such that a group of wires can pass through the interior of the first wire clip 1224 and the second wire clip 1219.

In some embodiments, when the earpiece assembly 12 is connected to the speaker module 11, it may be necessary for the connection section 1222 to be matched with the second through hole 1111. More details regarding the connection between the connection section 1222 and the second through hole 1111 can be found in embodiments of the present invention.

In some embodiments, in order to facilitate insertion of the connection section 1222 into the second through hole 1111 of the first speaker cabinet section 111 and improve the stability of the connection between the connection section 1222 and the second through hole 1111, as shown in FIG. 16, two through slots 1225 can be created in the end section 12221 of the connecting section 1222, intersecting one another, to divide the end section 12221 into four end segments. The end section 12221 can be divided into four end segments by two through slots 1225 intersecting one another so that the four end segments can be compressed and can then resiliently return to their original state. When the connecting section 1222 is inserted into the second through hole 1111, the four end segments can be pressed against each other so that the size of the combination of these end segments can be reduced to facilitate insertion of the connecting section 1222 into the second through hole 1111. It should be noted that the number end segments may be unlimited in the present invention, so that the number of end segments may be two, three, five, or another suitable number.

In some embodiments, a projection 1226 may extend from the periphery of the end segments. This connection section 1222 may be inserted into the speaker module 11, and this projection 1226 may be pinched and locked by the speaker module 11 to prevent the connection section 1222 from falling out of the speaker module 11. In particular, after insertion of the connecting section 1222 into the second through hole 1111, the four end segments can resiliently return to the uncompressed state, so that the protrusion 1226 on the periphery of the end segments becomes pinched and locked in the speaker module 11. In particular, the protrusion 1226 can be located in the containing space 110, and this protrusion 1226 can be clamped and locked at the edge of the connection area between the second through hole 1111 and the interior space 110. The reliability of the connection of the temple assembly 12 and the loudspeaker module 11 can be improved.

The connecting section 1222 can be configured to match and connect with the loudspeaker module 11. The other end of the elastic metal thread 1221 of the temple may be connected to the first section 121 of the body of the temple.

It should be noted that in one or more of the above embodiments, the earhook resilient cover 1223 may be configured to cover the portion of the bone conduction headset in contact with the wearer. Therefore, the location of the temple elastic cover layer 1223 may be similar to the temple elastic cover layer 183. In some embodiments, the temple elastic cover layer 1223 and the temple elastic cover layer 183 may be made of the same material. For example, the material of the elastic cover layer of the temple may be silica gel, rubber, plastic or other similar material. In some embodiments, the implementation of the modulus of elasticity of the specified elastic cover layer 1223 temples may be from 0.5 GPa to 2 GPa. In some embodiments, the implementation of the modulus of elasticity of the specified elastic cover layer may be from 0.8 GPa to 1.5 GPa. In some embodiments, the implementation of the modulus of elasticity of the specified elastic cover layer may be from 1.2 GPa to 1.4 GPa.

In some embodiments, the elastic cover layer 1223 of the temple may only cover the elastic metal thread 1221 of the temple. In some embodiments, the elastic cover layer 1223 of the temple may further cover the first section 121 of the temple housing and the second section 123 of the temple housing. In some embodiments, the earhook resilient cover 1223 may cover the second wire clip 1219. In some embodiments, it may be possible to make the power plug hole 1233, button hole 1235, or other similar hole open to the user for manipulation (eg, charging the battery through the power plug hole 1233). In some embodiments, the earhook elastic cover layer 1223 may also cover at least a portion of the connection section 1222, and may cover the first wire clip 1224.

In some embodiments, the acoustic input and output device 10 may further comprise a rear holder assembly 13 configured to couple to the earpiece assembly 12 such that the acoustic input and output device 10 can be in stable contact with the back of the user's head. For example, considering the bone conduction headset shown in FIG. 3, as an example, when a user is wearing a bone conduction headset, the rear holder assembly may be located on the back of the user's head. The back holder assembly can hold two temple assemblies connected to this back holder assembly in stable contact with the user's ears.

In some embodiments, the back holder assembly 13 may comprise a back holder connector and insertion portions 133 located at two ends of the rear holder connector, and these insertion portions 133 may be configured to facilitate a stable connection between the rear holder connector and the assembly. 12 temples.

The back holder elastic cover layer 132 may also cover at least a portion of the insertion portions 133.

The insertion portions 133 may be configured to match and insert into the temple assembly 12. In some embodiments, one side of the first section 121 of the temple body, remote from the connecting node 122 of the temple, can be configured with an insertion hole 1218 (as shown in Fig. 18). The insertion hole 1218 and the second groove 1212 may be positioned side by side. The insertion portions 133 can be matched and inserted into the insertion hole 1218. At least one of the insertion portions 133 may be configured with groups of notches 1331 spaced at some intervals in the length direction. In other words, these two groups of notches 1331 may be located on at least one of the insertion sections 133 at some interval in the length direction of the insertion sections 133, and each group of notches 1331 may contain at least one notch 1331. may be connected to the insertions 133 through one end of these insertions 133. One set of notches 1331 may be located close to the insertions 133 and another set of notches 1331 may be located at the end farthest from the insertions 133.

In some embodiments, the two sets of notches 1331 may be sequentially located in the direction from one end of the inserts 133 to the other end of the inserts 133. The notches 1331 near one end of the inserts 133 may be configured for positioning in the mold. The notches 1331 remote from this end of the insertion portions 133 may be configured to clamp and align with the first section 121 of the temple body.

In some embodiments, these two groups of notches 1331 may be divided into a first group of notches 1331 and a second group of notches 1331.
