The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example one

Referring to fig. 1 to 4, the present invention provides an earphone 100, which is a bone conduction earphone, including a bone conduction earphone main body 200, a first magnetic attraction 201 and a second magnetic attraction 202, wherein the bone conduction earphone main body 200 is used for transmitting sound by vibration, the first magnetic attraction 201 is installed on the bone conduction earphone main body 200, and the second magnetic attraction 202 is used for magnetically connecting with the first magnetic attraction 201.

Referring to fig. 6 and 7, in use, the bone conduction earphone body 200 is placed in the ear 600 for providing sound waves, and the second magnetic attraction member 202 is magnetically connected to the first magnetic attraction member 201 from the other side of the bone conduction earphone body 200, so that the bone conduction earphone body 200 is fixed in the ear 600 by means of magnetic attraction, and the whole earphone is worn in the ear. For example, the bone conduction headset main body 200 is fixed at the cavum concha, the scapha, the earlobe, etc. of the ear. Thus, the volume of the bone conduction earphone body 200 can be reduced, the bone conduction earphone body can be made into a shape similar to an earring, the volume and the weight are small, and the appearance is correspondingly improved when the bone conduction earphone body is worn in the ear.

Referring to fig. 1 to 4, the bone conduction earphone body 200 includes a bone conduction speaker 203 and a housing 204 covering the bone conduction speaker 203. The bone conduction speaker 203 is used to provide sound waves, and the housing 204 is used to contact the ear to protect the bone conduction speaker 203.

The bone conduction earphone main body 200 can be made into the shape of an in-ear earphone, namely, the shape of a flat hook is made so as to be conveniently fixed in the ear of a person and not fall off, and the bone conduction earphone main body 200 is more stably fixed in the ear of the person by combining with an ear hook, although the bone conduction earphone main body is not shown in the figure, the bone conduction earphone main body also belongs to the protection scope of the utility model.

Referring to fig. 10, in the embodiment, the bone conduction speaker 203 includes a magnetic assembly 10, a voice coil 20, an elastic assembly 30a, a conductive element 40 and a supporting member 50, wherein the magnetic assembly 10 is used for providing a magnetic field, and the voice coil 20 is used for being energized to generate vibration in the magnetic field.

In this embodiment, the elastic assembly 30a includes a first elastic member 31a and a second elastic member 32a, the first elastic member 31a and the second elastic member 32a are respectively mounted at two opposite ends of the magnetic assembly 10, the voice coil 20 is electrically connected to the first elastic member 31a or the second elastic member 32a, the support member 50 is respectively connected to the first elastic member 31a and the second elastic member 32a, a magnetic gap 11 is formed between the magnetic assembly 10 and the support member 50, and the voice coil 20 is mounted in the magnetic gap 11. In operation, the resilient member 30a vibrates in conjunction with the magnetic member 10.

In operation, the voice coil 20 is energized to produce vibrations in the magnetic field. The frequency response range and the tone quality of the bone conduction earphone body can be influenced by the vibration system, and because the magnetic component 10 is arranged between the elastic components 30a, the elastic components 30a and the magnetic component 10 vibrate together, so that the vibration mode is favorable for the response of low-frequency sound waves, and the tone quality of the low-frequency sound waves entering the ear is improved.

In addition, because the elastic members are directly installed at the two ends of the magnetic assembly 10, the magnetic assembly 10 is not surrounded by the elastic members, when the volume of the whole earphone body is reduced, the volume of the magnetic assembly 10 can be increased or unchanged, the influence on the volume of the magnetic assembly 10 is small, and the transmission effect of sound waves is not influenced when the volume of the whole earphone body is reduced.

Wherein, the magnetic component 10 is provided with a through hole 120. The provision of the through-hole 120 facilitates dissipation of heat generated during vibration. And, when the voice coil 20 is electrically connected to the first elastic member 31a, the voice coil 20 is connected to the first elastic member 31a through the conductive member, which can be drawn to the first elastic member 31a through the through hole 120. So that the voice coil 20 can be connected to the first elastic member 31a or the second elastic member 32 a. When the voice coil 20 is electrically connected to the first elastic member 31a, it is convenient to solder an external circuit to energize the voice coil 20, and such a soldering structure can reduce distortion, enhance air compliance, and improve the overall earphone body.

The magnetic assembly 10 at least includes a first magnetic member 12 and a second magnetic member 13 connected to one end of the first magnetic member 12, and the magnetic gap 11 is formed between the first magnetic member 12, the second magnetic member 13 and the supporting member 50.

Of course, the first magnetic member 12 and the second magnetic member 13 may have other shapes.

One of the first magnetic member 12 and the second magnetic member 13 is a magnet, and the other is a magnet or a metal capable of generating magnetic attraction with the magnet. For example, the first magnetic member 12 is a magnet, the second magnetic member 13 is a metal iron, or the first magnetic member 12 is a metal iron, and the second magnetic member 13 is a magnet, or both the first magnetic member 12 and the second magnetic member 13 are magnets, which can achieve the purpose of generating a magnetic circuit.

Of course, the magnetic assembly 10 may also include three or more magnetic members, as long as the first elastic member 31a and the second elastic member 32a are ensured to be located at two ends of the magnetic assembly 10. Of course, there is a tendency to select fewer magnetic members to form the magnetic assembly 10, so that the overall connection structure is more stable.

Further, the magnetic assembly 10 further includes a magnetic conductive member 14 connected to an end of the first magnetic member 12 away from the second magnetic member 13, wherein the magnetic conductive member 14 is connected to an end of the first magnetic member 12 away from the second magnetic member 13 for conducting magnetic. The second elastic member 32a is mounted at a position close to the magnetic conductive member 14. For example, the magnetic conductive member 14 is washer.

The first magnetic member 12 has a first through hole, the second magnetic member 13 has a second through hole, and the magnetic conductive member 14 has a third through hole, wherein the first through hole, the second through hole, and the third through hole together form the through hole 120.

The voice coil 20 is located in the magnetic gap 11, which is a space surrounded by the first magnetic material 12, the second magnetic material 13, and the support member 50. Therefore, the whole earphone body forms a whole body, and the shell is convenient to install in the later period.

The circuit board 21 may be a PCB, or a circuit-embedded rubber plate, a metal plate, etc., and may function to electrically connect the voice coil 20, the first elastic member 31a, or the second elastic member 32 a.

When the voice coil 20 is electrically connected to the first elastic member 31a through the circuit board 21, the circuit board 21 is connected to the first elastic member 31a through a conductive member that can be pulled to the first elastic member 31a by the through hole 120.

The first elastic element 31a and the second elastic element 32a are both steel plates or plastics with built-in circuits. Alternatively, the first elastic member 31a and the second elastic member 32a may also be conductive metal sheets, and both may play a role in transmitting vibration.

The first elastic element 31a is installed at an end of the second magnetic element 13 far away from the first magnetic element 12, and the second elastic element 32a is installed at a position close to an end of the first magnetic element 12 far away from the second magnetic element 13 or a position of the magnetic conductive element 14 far away from an end of the second magnetic element 13. Such a structure makes the voice coil 20 have a large vibration space and ensures the stability of the entire vibration of the magnetic circuit.

In this embodiment, a gap is formed between the second elastic member 32a and the circuit board 21. This leaves room for the vibration of the second elastic member 32a, improving the sound quality of the earphone body and reducing distortion.

When the voice coil 20 is electrically connected to any one of the first elastic member 31a and the second elastic member 32a, the electrically connected first elastic member 31a or second elastic member 32a is provided with a pad so as to be electrically connected to an external circuit, so that the entire earphone body is electrically conducted.

In order to facilitate connection of an external circuit, when the second elastic member 32a is electrically connected to the voice coil 20, the circuit of the second elastic member 32a may be led to the first elastic member 31a, and a pad or a circuit board may be provided through the first elastic member 31a to connect the external circuit. For example, the circuit of the second elastic member 32a is wound to the first elastic member 31a through the support member 50.

The conductive member 40 is an element for vibration conduction of sound, which is connected to the second elastic member 32a, and when the second elastic member 32a vibrates, the vibration is transmitted to the conductive member 40. The conductive element 40 may be a piezoelectric ceramic sheet, a PC conductive sheet, or other conductive elements.

The supporting member 50 is used for supporting the first elastic element 31a and the second elastic element 32a, and providing support so that they do not deform greatly, so that the magnetic circuit system can generate vibration together to ensure the stability of the structure. The support member 50 may be made of, for example, plastic, iron, low carbon steel, or the like. The connection between the supporting member 50 and the first and second

elastic members

31a and 32a may be made by gluing, connecting members, or the like.

The support member 50 is generally annular in shape to facilitate cooperation with the above-described structure.

Further, the bone conduction earphone body 100 further includes a conductive block 60, the conductive block 60 connects the conductive element 40, the second elastic element 32a and the circuit board 21, and the second elastic element 32a is electrically connected to the circuit board 21 through the conductive block 60. The second elastic member 32a can be electrically conducted without contacting the circuit board 21 by the conductive block 60.

The conductive manner of the conductive block 60 may be set as required, and the conductive block itself may be conductive, or may be conductive by setting a conductive member. For example, the conductive block 60 includes a positioning block and a conductive member installed in the positioning block, and the positioning block is connected to the second elastic member 32a, the circuit board 21 and the conductive member 40, respectively. Alternatively, the conductive block 60 is made of a conductive material, and the conductive block 60 is directly contact-electrically connected to the second elastic member 32a and the circuit board 21.

In this embodiment, the conductive member is a conductive spring.

The first magnetic attraction piece 201 may be mounted on the housing 204, or may be a metal piece directly used as a housing of the bone conduction speaker 203.

For example, the second magnetic attraction member 202 is a magnet, and the housing 204 is a metal housing magnetically attracted with the second magnetic attraction member 202, and the metal housing forms the first magnetic attraction member 201. The metal housing is for example a ferrous housing.

The soft shell is, for example, a silica gel shell.

Therefore, the magnetic body in the second magnetic part 202 is not exposed outside, the appearance is better, and the function is not affected. The flexible shell is, for example, a silicone shell, a plastic shell, or the like.

Further, the earphone 100 further includes a conductive element 205 and a control component 206, wherein the control component 206 is electrically connected to the bone conduction speaker 203 through the conductive element 205. This may control the operation of the bone conduction speaker 203 by the control component 206.

In operation, the voice coil 502 is energized to vibrate in the magnetic field generated by the magnetic assembly 501, and the diaphragm 503 and the conductor 504 vibrate accordingly. Because the magnetic component 501 at least comprises two combined magnetic parts, when the volume of the whole earphone body is reduced, the volume of the magnetic component 501 can be unchanged or enlarged, the influence on the volume of the magnetic component 501 is small, and the transmission effect of sound waves is not influenced when the volume of the whole earphone body is reduced, so that the tone quality is effectively ensured.

Of course, the first magnetic element 506 and the second magnetic element 507 may also take other shapes.

Of course, the magnetic assembly 501 may also include three or more magnetic elements. There is a tendency to select fewer magnetic members to form the magnetic assembly 501, so that the overall connection structure is more stable.

Further, the magnetic assembly 501 further includes a first magnetic conductive member 510 connected to an end of the first magnetic member 506 close to the vibrating member 503, and a second magnetic conductive member 511 connected to an end of the second magnetic member 507 close to the vibrating member 503. The first magnetic conductive member 510 and the second magnetic conductive member 511 can function as magnetic conductors. The first magnetic conductive member 510 and the second magnetic conductive member 511 can be a metal that generates magnetic attraction, or can be a magnet, preferably a metal that generates magnetic attraction, such as ferrous metal.

Further, the magnetic assembly 10 further includes a third magnetic conductive member 513, and the third magnetic conductive member 513 is mounted on the ends of the first magnetic member 506 and the second magnetic member 507 far away from the vibration member 503. The third magnetic conductive member 513 can serve the purpose of mounting the first magnetic member 506 and the second magnetic member 507, and can also serve the function of magnetic conduction. The third magnetic conductive member 513 may be a metal that generates magnetic attraction, or may be a magnet, preferably a metal that cooperates with the magnet, such as iron.

The third magnetic conductive member 513 and the second magnetic member 507 may be provided separately or integrally. The T-shaped iron is formed after the T-shaped iron body is integrally arranged, and the T-shaped iron is more convenient to install. When the third magnetic conducting member 17 and the second magnetic member 12 form a T-shaped iron, the second magnetic conducting member 16 needs to be removed because both the third magnetic conducting member 17 and the second magnetic member 12 can conduct magnetism.

The voice coil 502 is mounted within the magnetic gap 509 of the magnetic assembly 501 described above. The voice coil 502 cuts magnetic lines of force to generate electromotive force, and the shape, structure, and material thereof are not limited as long as the function can be achieved.

In this embodiment, the voice coil 502 is in the shape of a ring and is directly mounted in the annular magnetic gap 509.

A vibrating member 503 is installed near one end of the magnetic member 501, the vibrating member 503 is connected to the voice coil 502 and is electrically connected to the voice coil 502, thereby electrically connecting the entire earphone body, and the vibrating member 503 vibrates therewith when the voice coil 502 vibrates, thereby transmitting the vibration to the conductive member 504.

In this embodiment, a pad is provided at an outer end of the vibrating member 503, and an external circuit is connected to the pad, thereby conducting the circuit of the entire earphone body. Of course, the vibrating member 503 may conduct an external circuit in other manners.

In this embodiment, the vibrator 503 is a vibrating piece. The thickness of the vibrating plate is smaller, and vibration is more conveniently transmitted.

In this embodiment, the vibrator 503 is made of a hard material and houses a circuit element, and the voice coil 502 is connected to the vibrator 503 and electrically connected to the circuit element. Since the voice coil 502 is directly connected to the vibrating member 503, the vibrating member 503 is made of a hard material, so that stability when the vibrating member 503 is connected to the voice coil can be ensured, and stability when the vibrating member 503 and the voice coil 502 vibrate can be ensured. In contrast, in a general soft vibrator, the voice coil 502 needs to be connected to an auxiliary member or a gap needs to be provided between the voice coil 502 and the auxiliary member.

For example, the vibrating member 503 is a steel sheet, a plastic sheet, or a carbon fiber sheet with a built-in circuit element. The circuit module 208 is electrically connected to the vibrating member 503.

Of course, the vibrating member 503 may be made of other elastic members, such as ordinary metal sheet, but the stability effect is not as good as that of the hard material.

The conductor 504 is connected to the vibrator 503 and is an element for vibrating and conducting sound. When the vibrating member 503 vibrates, the vibration is transmitted to the conductive member 504. The conductive element 504 may be a piezoelectric ceramic plate, a PC conductive plate, or other conductive elements.

In this embodiment, the conducting element 504 is connected to the vibrating element 503 at a side away from the magnetic assembly 501.

The supporting member 505 serves to support the vibrator 503 and the magnetic assembly 501, and provides support to stabilize the mounting structure of the vibrator 503 and the magnetic assembly 501. The support member 505 may be made of, for example, plastic, iron, low carbon steel, or the like. The connection between the supporting member 505 and the vibrating element 503 and the magnetic assembly 501 may be by gluing, connecting element connection, etc.

The support member 505 may be made of metal, plastic, and other hard materials.

The supporting member 505 may be supported only between the magnetic assembly 501 and the vibrator 503, may wrap both sides of the magnetic assembly 501, or may wrap only one side of the magnetic assembly 501. In this embodiment, the supporting member 505 is in the shape of a ring and is installed between the magnetic assembly 501 and the vibrating member 503.

In other embodiments, the supporting member 505 is annular and located between the magnetic assembly 201 and the vibrating member 503 and covers one side of the magnetic assembly 501. Alternatively, the support member 505 is ring-shaped and covers both sides of the magnetic assembly 501.

In this embodiment, the bone conduction speaker 800 further includes a circuit board 512, the circuit board 512 is mounted on a surface of the third magnetic conductive member 513 away from the magnetic component 501, and the vibrating member 503 is electrically connected to the circuit board 512 through a conductive member. The circuit board 512 can be used to connect with external circuits more conveniently. In an embodiment, a first wire slot is formed outside the supporting component 505, a second wire slot is formed outside the first magnetic conducting member 510, third wire slots are formed outside the first magnetic member 506, and the conductive member is sequentially guided to the circuit board 512 by the first wire slot, the second wire slot, and the third wire slot. The wire groove is arranged, on one hand, the conductive piece can be conveniently guided to the circuit board 512, on the other hand, the conductive piece can be hidden and not exposed, so that the volume of the shell for wrapping the whole earphone main body can be reduced, and the miniature earphone main body can be conveniently prepared. The conductive member is, for example, a wire, a conductive sheet, etc.

When the supporting member 505 covers both sides of the magnetic assembly 501, a slot may be formed in the supporting member 505, and the conductive member may extend from the slot of the supporting member 505 to connect to the circuit board 512.
