Example one

1 to 4, the present invention provides an earphone 100, which is a bone conduction earphone, and includes a bone conduction earphone body 200, a first magnetic member 201, and a second magnetic member 202. The bone conduction earphone body 200 is used for vibration To transmit sound, the first magnetic member 201 is installed on the bone conduction earphone main body 200, and the second magnetic member 202 is used for magnetic connection with the first magnetic member 201.

For example, the bone conduction earphone main body 200 is fixed to the concha cavity, the navicular, and the earlobe of the ear. In this way, the volume of the bone conduction earphone main body 200 can be reduced, and it can be made into an earring-like shape, with a smaller volume and weight, so that it can be worn in the ear and the aesthetics is correspondingly improved.

1 to 4, the bone conduction earphone main body 200 includes a bone conduction speaker 203 and a shell 204 covering the outside of 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, that is, it is made into a flat hook shape to facilitate fixing in the human ear without falling, and the ear hook can be combined to more stably fix the earphone main body 200 in the human ear. It is not shown in the figure, but it also belongs to the protection scope of the present invention.

10, in this embodiment, the bone conduction speaker 203 includes a magnetic assembly 10, a voice coil 20, an elastic assembly 30, a conductive member 40, and a supporting member 50. The magnetic assembly 10 is used to provide a magnetic field, and the voice coil 20 is used to energize Vibrate in the magnetic field.

In this embodiment, the elastic component 30 is an elastic component 30a. The elastic component 30a includes a first elastic element 31a and a second elastic element 32a. The first elastic element 31a and the second elastic element 32a are respectively mounted on 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 supporting member 50 is respectively connected to the first elastic member 31a and the second elastic member 32a, and a magnetic gap 11 is formed between the magnetic assembly 10 and the supporting member 50, The voice coil 20 is installed in the magnetic gap 11. During operation, the elastic component 30a and the magnetic component 10 vibrate together.

During operation, the voice coil 20 is energized and vibrates in the magnetic field. The frequency response range and sound quality of the bone conduction earphone body will be affected by the vibration system. Since the magnetic component 10 is between the elastic components 30a, the elastic component 30a and the magnetic component 10 vibrate together. This vibration mode is conducive to the response of low-frequency sound waves. Improve the sound quality of low-frequency sound waves.

In addition, since the elastic members are directly mounted on the two ends of the magnetic assembly 10, the magnetic assembly 10 is not surrounded by the elastic members. When the volume of the entire earphone body is reduced, the volume of the magnetic assembly 10 can be larger or unchanged. If the impact is small, the sound wave transmission effect will not be affected when the volume of the entire headphone body is reduced.

Wherein, the magnetic component 10 is provided with a through hole 120. The provision of the through hole 120 is beneficial to dissipate the heat generated in the vibration process. Moreover, 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 a conductive member, and the conductive member can be pulled to the first elastic member 31a by the through hole 120. In this way, the voice coil 20 can be connected to the first elastic member 31a or the second elastic member 32a.

For example, the first magnetic member 12 is a magnet, the second magnetic member 13 is metallic iron, or the first magnetic member 12 is metallic iron, and the second magnetic member 13 is a magnet, or the first magnetic member 12 and the second magnetic member 13 are both As a magnet, both can achieve the purpose of generating a magnetic circuit.

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

When the second elastic member 32 a vibrates, the vibration is transmitted to the conductive member 40. The conductive member 40 can generally be a piezoelectric ceramic sheet, a PC conductive sheet, or other conductive elements.

The function of the supporting member 50 is to support the first elastic member 31a and the second elastic member 32a, and provide support so that it will not be greatly deformed, so that the magnetic circuit system can jointly generate vibration and ensure the stability of the structure. The supporting member 50 may be made of materials such as plastic, iron, low carbon steel, etc., for example. The connection between the supporting member 50 and the first elastic member 31a and the second elastic member 32a can be made by gluing, connecting member connection, or the like.

For example, the first magnetic piece 506 is a magnet, the second magnetic piece 507 is a metal iron, or the first magnetic piece 506 is a metal iron, and the second magnetic piece 507 is a magnet, or the first magnetic piece 506 and the second magnetic piece 507 are both As a magnet, both can achieve the purpose of generating a magnetic circuit.

Of course, the first magnetic member 506 and the second magnetic member 507 can also adopt other shapes.

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

Further, the above-mentioned magnetic assembly 501 further includes a first magnetic member 510 connected to an end of the first magnetic member 506 close to the vibrating member 503 and a second magnetic member 511 connected to an end of the second magnetic member 507 close to the vibrating member 503. The first magnetic permeable member 510 and the second magnetic permeable member 511 can play a role of magnetic permeability. The first magnetically conductive member 510 and the second magnetically conductive member 511 may be a metal that generates a magnetic attraction, or a magnet, preferably a metal that generates a magnetic attraction, such as ferrous metal.

Furthermore, the above-mentioned magnetic assembly 10 further includes a third magnetic conductive member 513, and the third magnetic conductive member 513 is installed at the ends of the first magnetic member 506 and the second magnetic member 507 away from the vibrating member 503. The third magnetically conductive member 513 can serve the purpose of installing the first magnetic member 506 and the second magnetic member 507, and can also perform a magnetically conductive role. The third magnetic conductive member 513 can be a metal that produces a magnetic attraction, or a magnet, preferably a metal that cooperates with the magnet, such as iron.

The third magnetic member 513 and the second magnetic member 507 may be provided separately or integrally. A T-shaped iron is formed after being integrated, and the T-shaped iron is easier to install. When the third magnetically conductive member 17 and the second magnetic member 12 form a T-shaped iron, since both the third magnetically conductive member 17 and the second magnetic member 12 can conduct magnetism, the second magnetically conductive member 16 needs to be removed.

The voice coil 502 is installed in the magnetic gap 509 of the above-mentioned magnetic assembly 501. The function of the voice coil 502 is to cut the lines of magnetic force and generate electromotive force. As long as this function can be realized, the shape, structure, and material of the voice coil 502 are not limited.

When the voice coil 502 vibrates, the vibrating member 503 will vibrate accordingly. Thus, the vibration is transmitted to the conductive member 504.

In this embodiment, the outer end of the vibrating member 503 is provided with a pad, and an external circuit is connected through the pad, so as to conduct the circuit of the entire earphone main body. Of course, the vibrating element 503 can also conduct the external circuit in other ways.

In this embodiment, the vibrating element 503 is made of a hard material and has a built-in circuit element, and the voice coil 502 is connected to the vibrating element 503 and electrically connected to the circuit element. Since the voice coil 502 is directly connected to the vibrating member 503, and the vibrating member 503 is made of a hard material, the stability when connected to the voice coil can be ensured, and the stability of the vibrating member 503 and the voice coil 502 when vibrating is ensured. However, the general soft vibrating part needs to rely on auxiliary components to connect the voice coil 502 or set a gap with the voice coil 502.

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

Of course, the vibrating member 503 can also be made of other elastic elements, for example, made of ordinary metal sheets, but the stability effect is not as good as that of hard materials.

The conductive member 504 is connected to the vibrating member 503 and is an element used for vibration and sound transmission. When the vibrating member 503 vibrates, the vibration is transmitted to the conductive member 504. The conductive member 504 may generally be a piezoelectric ceramic sheet, a PC conductive sheet, or other conductive elements.

In this embodiment, the conductive member 504 is connected to the side of the vibrating member 503 away from the magnetic component 501.

The function of the supporting member 505 is to support the vibrating member 503 and the magnetic assembly 501, and to provide support to make the installation structure of the vibrating member 503 and the magnetic assembly 501 more stable. The supporting member 505 may be made of materials such as plastic, iron, low carbon steel, etc., for example. The connection between the supporting member 505 and the vibrating member 503 and the magnetic assembly 501 can be made by gluing, connecting member connection, or the like.

The supporting member 505 can be made of metal, plastic, or other hard materials.

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

In other embodiments, the supporting member 505 has a ring shape, is located between the magnetic component 201 and the vibrating component 503 and covers one side of the magnetic component 501. Alternatively, the supporting member 505 has a ring shape and is wrapped on both sides of the magnetic assembly 501.

In this embodiment, the aforementioned bone conduction speaker 800 further includes a circuit board 512, the circuit board 512 is mounted on the side 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 one embodiment, a first wire slot is provided on the outside of the supporting member 505, a second wire slot is opened on the outer side of the first magnetic conductive member 510, and a third wire slot is provided on the outer side of the first magnetic member 506. A wire groove, a second wire groove, and a third wire groove are guided to the circuit board 512. On the one hand, the setting of the wire groove can facilitate the guiding of the conductive element to the circuit board 512, on the other hand, it can hide the conductive element and prevent the conductive element from being exposed, so that the volume of the shell covering the entire earphone body can be reduced, which is convenient for preparation Into a miniature headphone body. The conductive element is, for example, a wire, a conductive sheet, and so on.

When the supporting member 505 covers both sides of the magnetic assembly 501, a wire slot can be opened in the supporting member 505 at this time, and the conductive member can extend from the wire slot of the supporting member 505 to be connected to the circuit board 512.
