The master earphone has a master-slave role, and the master earphone bears the dual roles of communicating with the player and the slave earphone at the same time, while the slave earphone only communicates with the master earphone, so the power consumption of the master earphone is larger than that of the slave earphone. When the master earphone is low in power, the binaural wireless earphone cannot be used even if the slave earphone is high in power.

Therefore, there remains a need for an effective binaural wireless headset communication solution.

Detailed Description

Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As described above, in the binaural wireless headset, the power consumption of the master headset is larger than that of the slave headset, and when the power consumption of the master headset is insufficient, the master headset cannot be used even if the power consumption of the slave headset is sufficient.

In order to solve the above problems, the inventor proposes a binaural wireless headset and a communication control method thereof, which implement switching between a master earphone and a slave earphone through communication between a left earphone and a right earphone in the binaural wireless headset, so as to ensure uniform power consumption of the binaural headset, improve the use efficiency, and prolong the use time.

As shown in fig. 1, the binaural wireless headset 100 of the present invention may include a left ear headset 110 and a right ear headset 120. Wherein each of the left ear earphone 110 and the right ear earphone 120 may include a power supply 111 (121), a first wireless communication module 112 (122), and a second wireless communication module 113 (123).

Here, the left ear headset 110 and the right ear headset 120 may be used in pair. For example, left ear headphone 110 is adapted to be worn by a user's left ear and right ear headphone 120 is adapted to be worn by a user's right ear. The left ear headphone 110 and the right ear headphone 120 may have different shapes, respectively adapted to the left/right ears of the human body. Alternatively, the left ear earphone 110 and the right ear earphone 120 may have the same shape, and may be suitable for being worn by both the left ear and the right ear of the user, and at this time, the left and right ears of the human body play a role of identification.

The power supply 111 (121) is used for supplying power to the left ear (right ear) earphone and various power utilization modules (such as the first/second wireless communication module, the audio playing module, the processor and the like) arranged on the earphone. The power source 111 (121) may be a battery, such as a primary battery (e.g., a zinc-manganese battery, a zinc-mercury battery, etc.), a rechargeable battery (e.g., a rechargeable secondary battery), or the like. The power source 111 (121) may be directly or indirectly connected to each power consuming module to supply power thereto.

The first wireless communication module 112 (122) is used for communicating with an external signal source.

The external signal source may emit an external signal, and may be, for example, a mobile phone, a smart phone, a mobile notebook computer, a tablet personal computer (IPAD), a Personal Digital Assistant (PDA), or the like, and preferably may be a mobile device, which is convenient for a user to carry about.

The extraneous signal may include, but is not limited to, being an extraneous audio signal. In a preferred embodiment, the extraneous signal may be a binaural audio signal. When the external signal is an audio signal, the left and right ear earphones may also have corresponding other modules, such as an audio playing module, to play the audio signal. The left and right earphones may also have other corresponding modules when the extraneous signal is other.

The first wireless communication module 112 (122) can receive an external signal transmitted by an external signal source in a wireless communication manner in its operating state, and does not receive an audio signal when it is in an off state or a sleep state. The wireless communication means may be one or more of Bluetooth (Bluetooth), near field magnetic communication (NFC), CDMA2000, GSM, infrared (IR), ISM, RFID, UMTS/3GPPw/HSDPA, UWB, wiMAX Wi-Fi and ZigBee, etc.

The second wireless communication module 113 of the left ear earphone and the second wireless communication module 123 of the right ear earphone can communicate with each other, for example, the two earphones can transmit audio signals or data to each other. The wireless communication method between the second wireless communication modules may be one or more of the above wireless communication methods.

In operation, one of the left ear earphone 110 and the right ear earphone 120 may be used as a master earphone and the other as a slave earphone, the first wireless communication module 112 of the master earphone operates to receive an external signal from an external signal source, the first wireless communication module 122 of the slave earphone is in an off state or a low power mode (e.g., a sleep state), and the second wireless communication module 113 of the master earphone forwards at least a portion of the external signal to the second wireless communication module 123 of the slave earphone.

Here, the first wireless communication module of the slave headset does not receive an external signal transmitted from an external signal source when it is in an off state or a low power mode.

When the external signal may be a two-channel audio signal, the first wireless communication module of the master earphone receives the two-channel audio signal, and the second wireless communication module of the master earphone forwards a channel signal corresponding to the slave earphone to the second wireless communication module of the slave earphone.

The master and slave earpieces may also include a signal input module, such as a microphone, to facilitate collection of audio signals or data. At this time, the slave earphone may transmit the input audio signal or data to the master earphone via the second wireless communication module 123 to implement communication.

In order to ensure that the two earphones do not interfere with each other in the working process, the communication modes of the two wireless communication modules of the earphones can be different. The first wireless communication module and the second wireless communication module may have different operating frequency ranges. For example, the operating frequency range of the first wireless communication module may be higher than the operating frequency range of the second wireless communication module. For example, the operating frequency range of the first wireless communication module may be 300MHz to 3000MHz, such as around 2.4 GHz; the operating frequency range of the second wireless communication module may be 1MHz to 30MHz, for example, around 10 MHz.

The first wireless communication module and the second wireless communication module may have different power consumptions. For example, the power consumption of the first wireless communication module may be greater than the power consumption of the second wireless communication module to ensure that the first wireless communication module communicates with the external signal source normally.

In combination with specific use cases, different communication modes can be given to the two wireless communication modules according to the distance of signal transmission. For example, the first wireless communication module may be a long-range communication module, and the second wireless communication module may be a short-range communication module. Here, far distance and near distance are relative concepts, and far distance is suitable to mean that the distance between the general external signal source and the earphone is relatively long, for example, more than 0.5 m. A close range is suitably one where the transmission distance between the two earphones is relatively close, which may be in the range of human head sizes, for example within 30 cm. Preferably, the first wireless communication module may be a Bluetooth (Bluetooth) communication module, and the second wireless communication module may be a Near-field magnetic communication (Near-field magnetic identification communication) module.

Because the main earphone not only communicates with an external signal source, but also communicates with the slave earphone, the power consumption of the main earphone is larger than that of the slave earphone, and when the power of the main earphone is insufficient, the slave earphone cannot be used. Therefore, master-slave switching conditions can be added to the double-ear wireless earphones, so that the double-ear wireless earphones can respond to the condition that the master-slave switching conditions are met, the master earphone is switched to a new slave earphone, and the slave earphone is switched to a new master earphone. Therefore, the master-slave relation of the two earphones can be switched in real time, and the electricity consumption of the double-ear earphones is ensured to be uniform.

For real-time, intelligent switching of the two-earphone master-slave relationship, the binaural wireless earphone may further comprise a processor to perform the switching process. Fig. 2 illustrates a binaural wireless headset according to an embodiment of the invention.

As shown in fig. 2, in addition to containing the modules shown in fig. 1, the left ear headphone 110 can include a processor 114 and the right ear headphone can include a processor 124.

The processors of the left ear earphone 110 and the right ear earphone 120 can transmit or receive related instructions to each other via the second wireless communication module to realize the switching of the master-slave relationship.

For example, in case that the master-slave switching condition is satisfied, the processor of the master earphone may send a switching instruction to the slave earphone via the second wireless communication modules of the master earphone and the slave earphone in response to the master-slave switching condition being satisfied.

In response to the switching instruction, the processor of the slave earphone may activate its first wireless communication module to receive an extraneous signal from an external signal source and transmit a ready signal to the master earphone via the second wireless communication modules of the slave earphone and the master earphone.

In response to the ready signal, the processor of the master headset may instruct its first wireless communication module to enter an off state or low power mode. Thus, the master earphone is switched to a new slave earphone, and the slave earphone is switched to a new master earphone.

Because time is also needed for sending or receiving the related commands, the processor can also seamlessly switch the left-ear earphone 110 and the right-ear earphone 120 in order to avoid the phenomena of signal jamming and the like when switching the master-slave relationship of the earphones.

For example, in the case that a master-slave switching condition is satisfied, in response to receiving an extraneous signal from an external signal source in response to a first wireless communication module of the slave earphone being activated, the slave earphone forwards at least a portion of the extraneous signal to the master earphone via a second wireless communication module of the slave earphone and the master earphone.

At this time, the audio signal received by the first wireless communication module thereof may be played by the audio playing module of the slave headset.

The processor of the master earpiece instructs its first wireless communication module to enter an off state or low power mode after receiving at least a portion of the incoming signal from the slave earpiece. Therefore, seamless master-slave switching of the two earphones is achieved through the processor, the signal blocking problem possibly occurring in the switching process is avoided, and user experience is guaranteed.

Because the left ear earphone and the right ear earphone in the double-ear wireless earphone are configured in the same way, the initial master-slave relation of the two earphones can be determined in various ways.

For example, during production, a manufacturer may initially set one of the left-ear earphone and the right-ear earphone as a default master earphone, so as to clarify the master-slave relationship between the two earphones and avoid confusion. Or, the earphone with larger residual power can be used as the main earphone in response to the start of the binaural wireless earphone, so as to avoid the uneven power of the two earphones in the working process. Or, in response to the start of the binaural wireless earphone, the earphone with the accumulated working time of the first wireless communication module being shorter can be used as the main earphone, so as to prolong the whole service time of the binaural wireless earphone. Or, the earphone which is started first in the left-ear earphone and the right-ear earphone can be used as the main earphone, and sufficient preparation time is provided for the main earphone. It will be appreciated that the above examples are illustrative and not intended to be exhaustive and that the invention is not limited thereto and that the invention may be used to determine the initial master-slave relationship of two earpieces in other ways.

In the working process of the double-ear wireless earphone, master-slave switching conditions can be determined according to the using condition of the earphone, so that the using efficiency of the earphone is improved. For example, the master-slave switching condition may be that the remaining power of the power supply of the master earphone is lower than or equal to the power switching threshold, the earphone may include a power detection module (not shown in the figure) to detect the usage of the power of the earphone, and when the switching condition is met, the master-slave relationship is switched.

The charge switch threshold may be determined in a number of ways. For example, the power switching threshold may be a fixed power threshold, and the fixed power threshold may be set according to experience or experiment, and after one switching, the power supplies of the two earphones are almost exhausted at the same time, so as to improve the use efficiency.

The electric quantity switching threshold value can also be N fixed electric quantity threshold values which are gradually decreased one by one, the nth fixed electric quantity threshold value is used as a switching threshold value for switching for the nth time, N and N are natural numbers which are larger than 1, and N is smaller than or equal to N.

For example, the N fixed power thresholds are respectively 90%, 80%, 70% \8230ofthe total power of the main earphone power supply (which can be always regarded as 1), and the N fixed power thresholds are gradually decreased one by one. When the initial main earphone is used to 90% of the total electric quantity of the power supply of the initial main earphone, the first switching is carried out, at the moment, 90% of the total electric quantity of the power supply of the main earphone is a first fixed electric quantity threshold value, and the new main earphone after the first switching is finished is called a primary main earphone. When the primary main earphone is used to 80% of the total electric quantity of the power supply, the secondary main earphone is switched for the second time, at the moment, 80% of the total electric quantity of the power supply of the primary main earphone is a second fixed electric quantity threshold value, the new main earphone after the secondary switching is finished is called secondary main earphone 823082308230, and by parity of reasoning, the secondary main earphone is switched alternately for multiple times until the electric quantity of the power supply of the double-ear wireless earphone or the two earphones is stopped to be used up.

The electric quantity switching threshold value can also be a first preset proportion of the residual electric quantity of the current master earphone when the binaural wireless earphone is started or the master earphone and the slave earphone are switched last time, and the first preset proportion is smaller than 1.

For example, in this case, if the remaining power of the current main earphone is 90% of the total power of the power supply, and the first predetermined ratio is 80%, the power switching threshold value is 90% x 80% of the total power of the current main earphone power supply. The first predetermined ratio may be fixed, may be progressively decreased, or may be other values. Therefore, the master-slave switching can be repeatedly carried out until the electric quantity of the two earphones is almost exhausted.

The electric quantity switching threshold value can also be a second preset proportion of the residual electric quantity of the original main earphone when the main earphone and the auxiliary earphone are switched last time, and the second preset proportion is smaller than 1.

For example, if the remaining power of the original main earphone is 90% of the total power of the power supply and the second predetermined ratio is 80% when the main earphone and the slave earphone are switched last time, the power switching threshold value is 90% x 80% of the total power supply of the original main earphone. The second predetermined ratio may also be fixed, or may be progressively decreased or other values. Like this, switch again when the electric quantity of current main earphone is less than the electric quantity of preceding main earphone, avoid the electric quantity of main earphone still to be higher than from the earphone electric quantity, just switch for the electric quantity of former follow earphone is further less than former main earphone, aggravates the disequilibrium of electric quantity.

Therefore, no matter which one of the left ear earphone or the right ear earphone is used as the main earphone, the slow reduction of the electric quantity of the power supply can be ensured, the difference between the power supplies of the two earphones is balanced, the service efficiency of the power supply is improved, and the service life is prolonged.

The master-slave switching condition may also be that the accumulated working time of the first wireless communication module of the master earphone reaches a time switching threshold, and the earphone may include a timer, which accumulates the working time of the first wireless communication module of the master earphone, and performs master-slave relationship switching when the switching condition is satisfied.

The time switching threshold may also be determined in a number of ways, which may be similar to the way the power switching threshold is determined. For example, the time-switch threshold may be a fixed time threshold that is set empirically or experimentally.

The time switching threshold may also be M fixed time thresholds which are gradually decreased, an mth fixed time threshold is used as the switching threshold for the mth switching, M and M are both natural numbers greater than 1, and M is less than or equal to M.

The time switching threshold may also be a first predetermined ratio of accumulated working time of the first communication module of the current master earphone when the binaural wireless earphone is started or the master earphone and the slave earphone are switched last time, and the first predetermined ratio is smaller than 1.

The time switching threshold may also be a second predetermined ratio of accumulated working time of the first communication module of the original master earphone when the master earphone and the slave earphone are switched last time, where the second predetermined ratio is smaller than 1.

Both the first predetermined ratio and the second predetermined ratio may be fixed, or gradually decreasing, or other values. Therefore, the master-slave switching of the two earphones is executed through the accumulated working time of the first wireless communication module of the master earphone.

Because the accumulated working time of the first wireless communication module of the main earphone is gradually increased, the first preset proportion and the second preset proportion can also be gradually decreased, and the decreasing amplitude can be intelligently adjusted, so that the double-ear wireless earphones can automatically enter a protection state or an intelligent power-saving state when the power supply electric quantity of any earphone is low, and the service life of the earphones is prolonged.

It should be understood that the master-slave switching condition of the present invention may also be set according to other inventions, and may also allow the user to modify the master-slave switching condition.

The binaural wireless headset may also include an audio playback module 115 (125) shown in fig. 2 for playing back audio signals. In this way, when the external signal from the external signal source is a two-channel audio signal, the processor of the master earphone may decompose the audio signal into a left-channel audio signal suitable for being played by the left-ear earphone and a right-channel audio signal suitable for being played by the right-ear earphone, send the audio signal suitable for being played by the master earphone to the audio playing module thereof, and send the audio signal suitable for being played by the slave earphone to the slave earphone via the second wireless communication module thereof. The audio signal received from the processor of the headset's second wireless communication module 123 is sent to its audio playing module to play the audio signal.

In the binaural wireless earphone, in order to fixedly arrange each module in the earphone, each module may be respectively arranged on a chip, which may be a bluetooth chip, or a magnetic communication chip or other possible chips. In a preferred embodiment, each of the left ear earphone 110 and the right ear earphone 120 may include a bluetooth chip 116 (126) and a magnetic communication chip 117 (127) as shown in fig. 2, the first wireless communication module, the audio playing module and the processor being disposed on the bluetooth chip, and the second wireless communication module being disposed on the magnetic communication chip. Thereby, good communication of the binaural wireless headset is achieved.

It should be understood that the above exemplarily shows the positional relationship of the respective modules in the headset. In addition, a processor independent of the bluetooth chip may be provided, and the first and second wireless communication modules may be disposed on the same chip.

So far, the binaural wireless headset of the present invention is described in detail with reference to fig. 1 to 2.

The switching process of the master earphone and the slave earphone of the double-ear wireless earphone can be realized as a communication control method of the double-ear wireless earphone. The following description is made with reference to fig. 3 to 5.

As shown in fig. 3, in step S310, it is detected whether the binaural wireless headset satisfies a master-slave switching condition.

The master-slave switching condition may be preset by the merchant when the headset leaves the factory, or may be set by the merchant according to possible use conditions of the master headset, for example, whether the use of the master headset reaches a predetermined time threshold, a predetermined power threshold, and the like. Or, the user can adjust or modify the master-slave switching condition according to the own requirements, so as to reduce the earphone loss.

In step S320, in response to the master-slave switching condition being satisfied, the master earphone is switched to a new slave earphone, and the slave earphone is switched to a new master earphone.

Therefore, the master-slave relation of the two earphones is intelligently switched, the even power consumption of the double-ear wireless earphones is guaranteed, and the use efficiency is improved.

The inventive processor may perform the handover procedure of step S320. Fig. 4 shows a method flow diagram of a handover procedure according to an embodiment of the invention.

As shown in fig. 4, in response to the master-slave switching condition being satisfied, the master earphone sends a switching instruction to the slave earphone via the second wireless communication modules of the master earphone and the slave earphone in step S410.

Here, the switching instruction may be a pulse signal. For example, the signal "01" indicates "enter operating state", and the signal "00" indicates "exit operating state". The switching command may also be a command signal in other forms.

In step S420, in response to the switching instruction, the processor of the slave earphone activates the first wireless communication module of the slave earphone to receive an external signal from the external signal source and transmits a ready signal to the master earphone via the second wireless communication modules of the slave earphone and the master earphone.

The processor of the earphone receives a switching instruction from the second wireless communication module of the earphone, and responds to a switching signal to activate the first wireless communication module of the earphone so as to enable the first wireless communication module to enter an operating state to receive an external signal.

Activation of the first wireless communication module from the headset may be by sending a connection request from the headset to an external signal source to establish a connection with the external signal source.

The ready signal sent from the headset may also be a pulsed signal. For example, "ready" is indicated by signal "10".

In response to the ready signal, the processor of the master earpiece instructs its first wireless communication module to enter an off state or low power mode in step S430.

The second wireless communication module of the master earpiece receives the arm ready command, and the processor of the master earpiece, in response to the signal, sends a control command to its first wireless communication module to cause its first wireless communication module to enter an off state or low power mode.

Therefore, the first wireless communication module of the original slave earphone works, and the first wireless communication module of the original master earphone is in a closed state or a low-power mode, namely the master earphone is switched to a new slave earphone, and the slave earphone is switched to a new master earphone.

The switching between the master and the slave can be realized through the switching steps, however, a certain time is required for the sending and receiving of the switching command and the ready command, which may cause the problems of signal blockage, poor signal quality and the like in the switching process of the two earphones. Therefore, there is also a need for a seamless handover scheme. Fig. 5 shows a method flow diagram of a handover step according to another embodiment of the present invention.

As shown in fig. 5, in response to the first wireless communication module of the slave headset being activated to receive an extraneous signal from an external signal source, the slave headset forwards at least a portion of the extraneous signal to the master headset via the second wireless communication modules of the slave headset and the master headset in step S510.

That is, the first wireless communication module of the slave headset, while activated, may receive an extraneous signal, which may include, but is not limited to, an audio signal. In a preferred embodiment, the external signal is a two-channel audio signal, the external signal is received by the slave earphone, and simultaneously, the signal of the corresponding channel is played from the slave earphone (for example, the left channel signal is played from the slave earphone if the slave earphone is a left-ear earphone, and the right channel signal is played from the slave earphone if the slave earphone is a right-ear earphone), and the audio signal of the other channel is forwarded to the master earphone.

In step S520, the processor of the master headset instructs its first wireless communication module to enter an off state or a low power mode after receiving at least a portion of the incoming signal from the slave headset.

Therefore, seamless switching of the master earphone and the slave earphone is achieved, and user experience is guaranteed.

The master-slave switching process is as follows:

1. the master earphone sends a switching instruction to the slave earphone to require master-slave switching; while not disconnecting communication with the player and continuing to play the left channel audio signal.

2. The slave earphone starts the first wireless communication module and continuously plays the right channel signal sent by the master earphone.

3. A connection request is sent from the headphone to the player 200, a bluetooth connection is established with the player 200, the audio signal is received from the player 200, the audio signal is decomposed into left and right channel audio signals, and the right channel audio signal is played through the audio playing module 125.

4. The slave earpiece sends a ready signal to the master earpiece and a left channel audio signal to the master earpiece.

5. After receiving the ready signal, the master earphone starts to receive and play the left channel audio signal sent by the slave earphone; at the same time the connection to the player is disconnected.

6. The first wireless communication module of the primary earpiece enters an off state or low power mode.
