Description

Technical field

The utility model relates to accessories for communications, in particular to microphone-telephone devices placed with a support element on the head.

State of the art

Sony wired headphones are known with an input plug http://4review.ru/sony/1078-obzor-sony-sth-30-naushniki-vkladyshi-s-92-mm-membranoy.html see access date 08/14/2015. For listening to audio information, you must insert the plug of this device into the socket of the electronic device.

A disadvantage of the known technical solution is the inconvenience of operation: when the wire is touched, mechanical damage to the electronic device and wire breakage are possible.

An analogue of the proposed utility model is a device for connecting headphones to mobile devices described in the patent for utility model DE202008014989 U1 (published on 02.19.2009). It describes an individual means of reproducing sound for personal listening to audio information, comprising a first earphone, which is fixed on one side of the bow with an electro-acoustic transducer, housing, and earphone mount in the working position. Mounting the earphone in working condition is implemented through the bow. The electro-acoustic transducer is installed in the housing; the earphone mount is attached to the housing in the working position. Also, an individual means of reproducing sound for personal listening to audio information comprises a first part of a magnetic detachable connector provided with contacts, connected to an electro-acoustic transducer, which is located in the earphone. The connection is made by means of a wire, the first part being reciprocal with respect to the second part of the magnetic plug connector. That is, the mating part allows them to connect.

A disadvantage of the known technical solution is the need to bring a microphone, which can be located in a mobile device, as a result of which the wire can sag, forming a shape in the form of a loop, which increases the likelihood of damage and increases the likelihood of disconnecting the plug connector.

The prototype of the proposed utility model is the MusiCom sports headset described in application US 20120077549 A1 (published on March 29, 2012). The specified device contains a comforter, for example, made of elastic fabric, designed to be worn on the user's head and in which the first and second headphones are placed near the user's ears, and a microphone near the chin. The device also contains a magnetic detachable connector, consisting of two parts and placed at a distance from the source of the electrical signal. Moreover, the first part of the magnetic detachable connector is connected by a wire to the headphones and a microphone, and the second part is also connected by means of a wire to a slap switch. A “slap switch” is in turn connected by a wire to an electric signal source. A possible embodiment of the device is when the user uses his own headset (not described in the patent), which is connected to the source of an electric signal using a special connector, instead of a headguard with headphones and a microphone.

The disadvantage of the prototype is the lack of mechanical support for the correct position of the first part and the second part of the magnetic disconnectable connector. This is explained as follows. In accordance with paragraph 41, the pairing of the first part and the second part and the electrical contacts on them is ensured by only magnetic interaction, which does not provide an absolutely accurate pairing of the contacts, as a result of which the operation of the electrical circuit may be impaired.

The technical result of the invention is to ensure proper placement of the parts of the magnetic disconnectable connector relative to each other with the creation of conditions for contact between the contacts of the first part and the contacts of the second part.

Brief Description of the Drawings

The invention is illustrated by drawings (FIGS. 1, 2), where in FIG. 1 shows the main elements of the device, FIG. 2 is a front view of a first part of a magnetic plug connector.

Disclosure of invention

The figures indicate: individual means of reproducing sound directly into the ear of a person 1 (hereinafter referred to as individual means of reproducing sound), housing 2, means of attachment in the working position 3 (hereinafter referred to as attachment means), first earphone 4, second earphone 5, electric source signal 6, a magnetic detachable connector 7, one of the parts 8 of the magnetic detachable connector 7 (hereinafter referred to as the second part), the other part 9 of the magnetic detachable connector 7 (hereinafter referred to as the first part), od 10, electro-acoustic transducer 11, contacts 12 of the first part 9, protrusion 13.

The device is an individual means of reproducing sound for personal listening to audio information. In this case, the individual means of reproducing sound 1 according to the type of signal transmission is wired. The individual sound reproducing means 1 consists of a first earphone 4, a second earphone 5 (hereinafter collectively referred to as headphones), fastening means 3, wires 10 and the first part 9 of the magnetic plug connector 7.

Headphones can be of various types by design: plug-in to the auricle, intra-ear, plug-in to the ear canal, over-ear and full-size, completely covering the ear. The headphones consist of a housing 2, a fastening means 3 and an electro-acoustic transducer 11.

The material of the housing 2, in particular, can be made of metal, plastic, wood. The housing 2 accommodates an electro-acoustic transducer 11, internal wiring for the passage of an electrical signal to the electro-acoustic transducer 11, and internal channels for the passage of sound into the external auditory canal of a person.

The fastening means 3 is fixed on the housing 2, in which the electro-acoustic transducer 11 is located. The fastening means 3 is designed to fix the headphones in the working position with respect to the human ear. The fastening means 3 can be made in the form of a handle connecting the first earphone 4 and the second earphone 5. The handle is placed on the crown of the head or on the back of the head. The fastening means 3 can be carried out by means of earhooks or clips securing the earphones to the auricle, ear pads located in the auricle or external auditory canal and held there by elasticity.

Electro-acoustic transducers 11 are devices that convert electrical energy into acoustic. Depending on the principle of converting an electrical signal into an acoustic signal, electrodynamic and electrostatic converters are most common. Depending on the design features, electrodynamic converters are divided into coil, with balanced armature, isodynamic, orthododynamic. The principle of operation of electrodynamic transducers is based on the physical phenomenon of the occurrence of the corresponding force in a conductor placed in a constant magnetic field in the case of an electric current flowing through it. In coil electrodynamic transducers, a membrane is used, to which a coil with a wire and a permanent magnet are attached, in the magnetic field of which it is located. When AC is passed through the coil, a magnetic field arises that interacts with the magnetic field of the permanent magnet. As a result, the membrane begins to oscillate, repeating the electrical signal through a sound wave. Electrodynamic transducers with a balanced armature are characterized by a U-shaped plate (armature) around which the coil is located. An anchor can only move around an axis passing through the center of that part that is inside the magnetic field. Electrical signals cause fluctuations in the magnetic field, as a result of which the armature moves, which is transmitted to the membrane, which produces sound waves. The basis of isodynamic and ortodynamic electrodynamic converters is a thin and light film membrane with metal tracks deposited on it. It is placed between two magnets, when a current is applied to it, it is driven and oscillates between them. In isodynamic emitters, a rectangular membrane is used, in ortodynamic emitters - a round membrane. Electrostatic transducers use an ultra-thin membrane that is located between two electrodes. A high voltage is applied to the membrane, a large amplitude signal is applied to the electrodes. As a result, an alternating electrostatic field arises between the membrane and the electrodes, moving the membrane with sound frequency.

The electro-acoustic transducer 11 is connected by a wire 10 to a source of electrical signal 6. The wire 10 is a cord that is made of an appropriate number of flexible multi-wire conductive conductors with rubber or polyvinyl chloride insulation. The wire 10 consists of two sections: the upper section is branched and equipped with headphones, the lower section is doubled and provided with the first part 9 of the magnetic connector 7. Through the magnetic connector 7, the wire 10 is connected to an electric signal source 6.

A microphone is an electro-acoustic device that can convert sound vibrations, such as human speech, into electrical vibrations. The microphone can be mounted on the upper or lower portion of the wire 10 to ensure its electrical connection with the wire 10. The individual means of reproducing sound 1 may include a holder that is mounted on the housing of the first earphone 4 or second earphone 5, or on the mounting tool 3. A microphone is attached to the holder. The holder is configured to electrically connect the microphone to the wire 10. In the drawing, the holder and microphone are not shown. The microphone is connected by a wire 10 to the first part 9 of the magnetic detachable connector 7. The microphone contains a thin membrane that can oscillate under the influence of the pressure of sound vibrations of air. The microphone also contains means for converting the audio signal into an electric one.

The magnetic detachable connector 7 is a device for connecting the individual means of reproducing sound 1 to the source of the electric signal 6. The magnetic detachable connector 7 is formed by the first part 9 and the second part 8. The magnetic detachable connector 7 is designed to repeatedly connect and disconnect the first part 9 and the second part 8 without violation of their integrity, and electrical contact of the first part 9 and the second part 8 on mutually conjugate external surfaces. The first part 9 is located at the end of the lower portion of the wire 10. The second part 8 is located on or near the surface of the source of the electrical signal 6.

The first part 9 of the magnetic detachable connector 7 is made to provide a force of interaction with the second part 8 of the magnetic detachable connector 7, sufficient to hold them in a connected state, and to ensure that they can be opened with a sufficient applied force. For this, the interaction force should be greater than the gravity of the individual means of reproducing sound 1, but less than the force applied to the magnetic detachable connector 7 to disconnect the first part 9 and the second part 8. In the particular case, when a force equal to the jerk is applied to the wire 10 , the first part 9 is safely disconnected from the second part 8, while the source of the electric signal 6 remains in place. The strength of the interaction depends on several factors: on the mutual configuration of the first part 9 and the second part 8, the magnetic properties of the materials of the first part 9 and the second part 8, the location of the magnetic poles, the geometric shapes and sizes of the first part 9 and the second part 8.

In the proposed device, the first part 9 of the magnetic detachable connector 7 is provided with contacts 12 and a protrusion 13. The contacts 12 of the first part 9 are spaced along its outer surface perpendicular to its longitudinal axis. The protrusion 13 is located between the contacts 12 of the first part 9 on its outer surface perpendicular to its longitudinal axis. On the outer surface of the second part 8, perpendicular to its longitudinal axis, there are contacts responding to the electrical contacts 12 of the first part 9, and a recess made responsive to the protrusion 13 on the first part 9.

An element is responsive to another element if, at a specific arrangement of them relative to each other, they correspond to each other in configuration formed by magnetic fields, mate and form a reliable connection, including providing electrical contact between the corresponding electrical contacts. As a rule, the elements responding to each other are components of complex objects.

In another embodiment of the proposed device, the first part 9 and the second part 8 of the magnetic detachable connector 7 are made flat to ensure the natural position of the contacts for closing and opening the electric circuit.

In all versions, the materials of the first part 9 and second part 8 include substances having ferromagnetic properties to provide magnetic interaction. In one embodiment, the protrusion 13 in the first part 9 and the surface of the recess in the second part 8 have ferromagnetic properties. In another embodiment, the first part 9 and the second part 8 directly have ferromagnetic properties. The following variations are possible to ensure magnetic interaction: in the first part 9, a constant magnetic field source is located, the second part 8 contains magnetic material; the first part 9 contains magnetic material, in the second part 8 a constant magnetic field source is located; and in the first part 9, and in the second part 8 are sources of a constant magnetic field. In the proposed device, the source of the constant magnetic field is a permanent magnet. A permanent magnet is a product of a certain shape from a pre-magnetized ferromagnetic or ferrimagnetic material, capable of retaining significant magnetic induction after eliminating the magnetizing field. Permanent magnets typically use iron, nickel, cobalt, some rare earth alloys, and some natural minerals such as magnetites. Magnetic material is a non-magnetized material attracted to a magnet when interacting with it. Iron, cobalt, nickel and their alloys can be used as magnetic material. The use of strong magnets, such as neodymium, in this case is possible, but not desirable, since the interaction force in this case can be greater than the force applied to the magnetic detachable connector 7 to disconnect the first part 9 and the second part 8.

If magnets are located in both the first part 9 and the second part 8, then they are positioned with opposite poles to each other for mutual attraction. If the magnet is located in one of the parts (first part 9, second part 8), then the other part (first part 9, second part 8) respectively contains magnetic material. When approaching one of the poles of a magnet of magnetic material, the latter is temporarily magnetized. In this case, the pole of the magnetized material closest to the pole of the magnet will be opposite in name, and the distant pole of the same name. During magnetization of the magnetic material, the orientation of the dipoles in it is ordered, then the magnetic material is attracted to the magnet. Direct attraction of the opposite poles and conjugation of the outer surfaces of the first part 9 and the second part 8 in one embodiment ensure the correct fit of the protrusion 13 in the recess, in another version, the first parts 9 on the second part 8 relative to each other.

The shape of the protrusion 13 is made correct to increase the magnetic field strength. The increase in the magnetic field leads to an increase in the energy density of the magnetic field, thus increasing the attraction of the protrusion 13 to the recess. The shape of the protrusion 13 may be triangular, square, oval, round or hexagonal.

Also, the protrusion 13 can be made with smooth or angular outlines, but in such a way that the protrusion 13 is preferably perpendicular to the magnetic lines of force extending from the poles parallel to the longitudinal axes of the protrusion 13 and the recess. Then the magnetic flux penetrating the protrusion 13 will be maximum.

Due to the small size of the first part 9 and the second part 8, their interaction force is always less than the force that can be applied by a person to the magnetic detachable connector 7 to disconnect the first part 9 and the second part 8.

The electric signal source 6 is a mobile electronic device, in particular a mobile phone, an MP3 player, a laptop computer.

The implementation of the invention

The device is implemented as follows. The manufacture of individual means of sound reproduction 1 consists of several stages. Initially made headphones and a microphone. Attachment means 3 are attached to the cases 2 of the headphones. Electroacoustic transducers 11 are installed in the cases 2 of the headphones. 11. A microphone is attached to the wire 10. If the device includes a holder, attach the microphone to the holder, and the holder is fixed to the case of the first earphone 4 or second earphone 5 or fastening means 3. Electro-acoustic transducers 11 and a microphone are connected by a wire 10 and connected to a source of electric signal 6 by means of a magnetic detachable connector 7. Magnetic detachable soy initel 7 is made in the form of connection of the two parts (the first part 9 and second part 8). The first part 9 of the magnetic detachable connector 7 is installed at the end of the wire 10. On the outer surface of the first part 9, perpendicular to its longitudinal axis, the contacts 12 of the first part 9 and the protrusion 13 are located. The second part 8 of the magnetic detachable connector 7 is placed on the surface of the electric signal source 6. On the outer surface of the second part 8, perpendicular to its longitudinal axis, there are contacts responding to the electrical contacts 12 of the first part 9, and a recess made responsive to the protrusion 13 on the first part 9. In in another embodiment, the first part 9 and the second part 8 of the magnetic plug connector 7 are flat.

The device operates as follows. When approaching the first part 9 of the magnetic detachable connector 7 to the second part 8, they are reliably connected due to magnetic interaction. The protrusion 13 of the first part 9 is inserted into the recess of the second part 8. The outer flat surface of the first part 9 is firmly in shape to the outer flat surface of the second part 8. The contacts 12 of the first part 9 are in contact with the response contacts located on the second part 8 and form an electrical a circuit in which the source of electrical energy is the source of electrical signal 6. The source of electrical signal 6 provides an electrical signal, which is transmitted through a magnetic connector 10 through wire 10 and into lektroakusticheskie transducers 11 mounted in the housing 2 headphones. Electro-acoustic transducers 11 convert an electrical signal into an acoustic signal. If the headphones through the fastening means 3 are installed in the working position with respect to the person’s ear, then the acoustic signal enters the external auditory meatus.

The source of the electric signal 6 generates an electric signal, which is transmitted through a magnetic connector 10 through wire 10 and enters the electro-acoustic transducers installed in the microphone and provides their power. The pressure of the sound vibrations of the air acts on the microphone membrane, which begins to oscillate. Oscillations of the membrane excite electrical vibrations in electro-acoustic transducers. Electrical vibrations are transmitted through wire 10 through a magnetic plug connector 7 to a mobile electronic device, such as a mobile phone.

A magnetic detachable connector 7 protects the individual means of reproducing sound 1 and the source of the electric signal 6 from possible damage. In the particular case, when the wire 10 is touched during sports, the first part 9 of the magnetic plug connector 7 is safely disconnected from the second part 8, so that the source of the electric signal 6 remains intact. In addition, in the case of a conversation on a mobile electronic device, it is not necessary to bring the microphone located in the mobile electronic device to the user's mouth. As a result, there is no sagging of the wire 10 in the form of a loop, and the likelihood of damage during operation and the likelihood of disconnecting the individual means of reproducing sound 1 from a mobile electronic device are reduced. In another case, if the individual means of reproducing sound 1 is connected to such an electric signal source 6 as a computer, then removing a person from the workplace - getting up from a chair, the first part 9 is safely opened from the second part 8. Then both the wire 10 and the computer are not exposed damage.

Thus, the implementation of the first part 9 with the protrusion 13, and the second part 8 with the counter recess provides the correct placement of the parts of the magnetic disconnectable connector 6 relative to each other with the creation of conditions for contact between the contacts of the first part 9 and the response contacts of the second part 8. This is explained as follows. The protrusion 13 of the first part 9 when interacting with the response recess of the second part 8 in addition to magnetic coupling provides mechanical coupling. The result is a more accurate pairing of the first part 9 with the second part 8, while ensuring the exact interaction of the corresponding contacts of the first part 9 and the second part 8 with the least possible disruption of the electrical circuit.
