Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully below. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. 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, the present invention provides a bone conduction earphone 100, which includes an earphone main body 200 and an ear hook 201, wherein the earphone main body 200 is used for transmitting sound by vibration, and the ear hook 201 is connected to the earphone main body 200 for fixing the earphone main body 200 on a human ear 600.

Referring to fig. 3, in the bone conduction earphone, the ear hook 201 is used to fix the earphone main body 200 near the ear 600, so that the volume and weight of the earphone main body 200 can be reduced, the bone conduction earphone is worn on the ear, the ear loop is omitted, and the aesthetic property is correspondingly improved.

The earphone body 200 includes a bone conduction speaker 202, a control unit 203 electrically connected to the bone conduction speaker 202, and a housing 204 covering the bone conduction speaker 202 and the control unit 203. The bone conduction speaker 202 is used for vibration transmission of sound, the control part 203 is used for controlling the operation of the bone conduction speaker 202, and the housing 204 is used for contacting with the ear to protect the bone conduction speaker 202.

After the earphone body 200 is fixed, the bone conduction speaker 202 corresponds to a position outside the human ear close to the tragus for transmitting to the human ear through the tragus's ear bone, so that the human ear can hear the sound emitted by the bone conduction speaker 202, the control part 203 corresponds to the human ear and is displayed outside for human operation, and the operation of on, off, sound, etc. of the bone conduction speaker 202 can be controlled.

Referring to fig. 8, in the present embodiment, the bone conduction speaker 202 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 earphone main 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, and the vibration mode is favorable for the response of low-frequency sound waves and improves the tone quality of the low-frequency sound waves entering ears.

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 speaker 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 speaker 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 speaker effect.

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. The first magnetic member 12 and the second magnetic member 13 are connected in such a manner that the elastic members can be conveniently installed at both ends of the magnetic assembly 10 without affecting the cooperation of the magnetic circuit and the voice coil.

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 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.

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 loudspeaker forms a whole body, and the shell is convenient to install in the later period.

The earphone body 100 further includes a circuit board 21, and the voice coil 20 is electrically connected to the first elastic member 31a or the second elastic member 32a through the circuit board 21. Thereby enhancing the stability of the electrical connection. 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 speaker and reducing distortion.

When the voice coil 20 is electrically connected to any one of the first elastic member 31a or 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 speaker 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 earphone main 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.

The conductive member is a conductive spring.

Referring to fig. 2, for example, the control unit 203 includes a power supply module 207, a circuit module 208 electrically connected to the power supply module 207, and a switch module 209 electrically connected to the circuit module 208. The power supply module 207 may be, for example, a battery, a charger, or the like, and is preferably a small-sized battery. The switch module 209 may control the opening and closing of the bone conduction speaker 202. This allows the bone conduction speaker 202 to be controlled to operate without removing the bone conduction speaker 202. The circuit module 208 is electrically connected to the circuit board 21.

The switch module 209 is provided with a switch button 2090, and the bone conduction speaker 202 can be controlled by pressing the switch button 2090.

Referring to fig. 1, 4 and 6, the volume adjusting module 210 is provided with a volume button 2100, and the volume button 2100 can adjust the volume.

The control part 203 may correspond to the inside of the human ear or the outside of the human ear.

The shell 204 is a soft shell. When the soft shell is contacted with the human ear, the comfort level of the human ear can be ensured. Of course, the shell 204 can be made of hard material and can also perform its function, but the touch is not as good as a soft shell.

The earhook 201 is connected to the housing 204 for hanging on the ear of a person to fix the earphone main body 200.

In this embodiment, the ear hook 201 is connected to the housing 204 and extends from the top of the human ear 600 to the back of the human ear 600 to be hung on the human ear. The ear hook 201 is integrally shaped like a horn or an arc, and is convenient to be hung on the ear of a person.

Example four

Referring to fig. 9, the bone conduction earphone of the present embodiment is substantially the same as the bone conduction earphone of the first embodiment, except that the bone conduction speaker 500 of the present embodiment does not include the conductive block 60, the elastic component 30b includes a first elastic member 31b and a second elastic member 32b, the second elastic member 32b is directly attached and electrically connected to the circuit board 21, and a protrusion 33 protruding in a direction away from the circuit board 21 is disposed at an outer edge of the second elastic member 32b, so that a vibration space is formed between the protrusion 33 and the voice coil 20. This leaves sufficient space for the magnetic circuit system to vibrate.

The shape of the convex portion 33 is circular arc or square, the number of the convex portions 33 is one, two or more, and the convex portions 33 can be arranged continuously or at intervals. The size of the projection 33 may also be set as desired.

EXAMPLE five

Referring to fig. 10, the bone conduction earphone of the present embodiment is basically the same as the bone conduction earphone of the first embodiment, except that the bone conduction speaker 600 of the present embodiment: the elastic member 30c includes a first elastic member 31c and a second elastic member 32c without the conductive block 60 and the circuit board 21, the second elastic member 32c is made of a hard material and houses a circuit component, and the voice coil 20 is connected to the second elastic member 32c and electrically connected to the circuit component so that the voice coil 20 can be directly electrically conducted with the second elastic member 32 c.

For example, the first elastic element 31c and the second elastic element 32c are both steel sheets or plastics with built-in circuits.

The middle portion of the magnetic assembly 10 may be provided with a through hole 120, or may not be provided with the through hole 120, and fig. 3 shows the case where the through hole 120 is not provided.

EXAMPLE six

Referring to fig. 11, the bone conduction earphone of the present embodiment is substantially the same as the bone conduction earphone of the first embodiment, except that the bone conduction speaker 700 of the present embodiment has a different structure from the bone conduction speaker 202 of the first embodiment, the bone conduction speaker 500 of the present embodiment includes a magnetic component 501, a voice coil 502, a vibrating piece 503, a conducting piece 504 and a supporting member 505, the magnetic component 501 is used for providing a magnetic field to the voice coil 502, the voice coil 502 is used for cutting a magnetic induction line to generate an electromotive force, the vibrating piece 503 is used for connecting the voice coil 502, a circuit is turned on to transmit vibration, and the conducting piece 504 is used for vibrating and conducting sound waves.

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 loudspeaker 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 loudspeaker is reduced, so that the sound quality is effectively ensured.

The magnetic assembly 501 includes a first magnetic member 506 and a second magnetic member 507, a through hole 508 is formed in the middle of the first magnetic member 506, and the second magnetic member 507 is installed in the through hole 508, so that a magnetic gap 509 is formed between two opposite sides of the first magnetic member 506 and the second magnetic member 507. The first magnetic member 506 and the second magnetic member 507 can generate a strong magnetic field, and when the voice coil 502 is mounted in the magnetic gap 509, the magnetic induction lines can be cut strongly, thereby ensuring better sound quality.

The shapes of the first magnetic member 506 and the second magnetic member 507 may be set as required.

In one embodiment, the first magnetic member 506 has a ring shape to form a through hole 508 in the middle of the first magnetic member 506, and the second magnetic member 507 is a block shape and is installed in the through hole 508 without contacting the sidewall of the first magnetic member 506, thereby forming the magnetic gap 509. The second magnetic member 507 may be in the shape of a ring, a block, a bar, etc., and may be matched with the first magnetic member 506.

One of the first magnetic member 506 and the second magnetic member 507 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 506 is a magnet, the second magnetic member 507 is a metal iron, or the first magnetic member 506 is a metal iron, and the second magnetic member 507 is a magnet, or both the first magnetic member 506 and the second magnetic member 507 are magnets, which can achieve the purpose of generating a magnetic circuit.

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 513 and the second magnetic member 507 form a T-shaped iron, the second magnetic conducting member 511 needs to be removed because both the third magnetic conducting member 513 and the second magnetic member 507 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.

The voice coil 502 is in the shape of a ring and is mounted directly within the annular magnetic gap 509.

A vibrating member 503 is installed near one end of the magnetic assembly 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 speaker, and the vibrating member 503 vibrates therewith when the voice coil 502 vibrates, thereby transmitting the vibration to the conductive member 504.

The outer end of the vibrating member 503 is provided with a pad through which an external circuit is connected, thereby conducting the circuit of the entire speaker. Of course, the vibrating member 503 may conduct an external circuit in other manners.

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

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.

The conducting element 504 is connected to the vibrating element 503 on the 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 50 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 loudspeaker can be reduced, and the miniature loudspeaker 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.
