[0039] In order to facilitate the understanding of the present invention, the present invention will be described more fully below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0041] Embodiment 1
[0042] Please refer to Figures 1 to 4 The present invention provides an earphone 100, which is a bone conduction earphone, including a bone conduction earphone body 200, a first magnetic component 201 and a second magnetic component 202. The bone conduction earphone body 200 is used to transmit sound by vibration. The first magnetic component 201 is installed on the bone conduction earphone body 200, and the second magnetic component 202 is used to be magnetically connected to the first magnetic component 201.
[0043] Please refer to Figure 6 and Figure 7 When in use, the bone conduction earphone body 200 is placed in the ear 600 to provide sound waves, and the second magnetic member 202 is magnetically connected to the first magnetic 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 magnetic connection, so that the entire earphone is worn in the ear. For example, the bone conduction earphone body 200 is fixed in the concha cavity, scaphoid, earlobe and other positions of the ear. In this way, the volume of the bone conduction earphone body 200 can be reduced, and it can be made into an earring-like shape with a small volume and weight. When worn in the ear, the aesthetics is also improved accordingly.
[0044] Please refer to Figures 1 to 4The bone conduction earphone body 200 includes a bone conduction speaker 203 and a housing 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 and protect the bone conduction speaker 203.
[0045] The bone conduction earphone body 200 can be made into the shape of an in-ear earphone, that is, made into a flat hook shape, so as to be conveniently fixed in the human ear and prevent it from falling. Although it is not shown in the figure, it also falls within the protection scope of the present invention by combining with an ear hook to more stably fix the earphone body 200 in the human ear.
[0046] Please refer to Fig.10 In this embodiment, the bone conduction speaker 203 includes a magnetic component 10, a voice coil 20, an elastic component 30, a conductive member 40 and a supporting member 50. The magnetic component 10 is used to provide a magnetic field, and the voice coil 20 is used to be energized to generate vibrations in the magnetic field.
[0047] In this embodiment, the elastic component 30 is an elastic component 30a, and the elastic component 30a includes a first elastic member 31a and a second elastic member 32a, which are respectively mounted at opposite ends of the magnetic component 10, the voice coil 20 is electrically connected to the first elastic member 31a or the second elastic member 32a, the support component 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 component 10 and the support component 50, and the voice coil 20 is mounted in the magnetic gap 11. When working, the elastic component 30a and the magnetic component 10 vibrate together.
[0048] When working, 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 and improves the sound quality of low-frequency sound waves entering the ear.
[0049] In addition, since the elastic member is directly installed at both ends of the magnetic component 10, the magnetic component 10 is not surrounded by the elastic member. When the volume of the entire earphone body is reduced, the volume of the magnetic component 10 can be enlarged or remain unchanged, and the volume of the magnetic component 10 is less affected. Therefore, when the volume of the entire earphone body is reduced, the sound wave transmission effect is not affected.
[0050] Among them, the magnetic component 10 is provided with a through hole 120. The provision of the through hole 120 is conducive to dissipating the heat generated during 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 component, and the conductive component 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. When the voice coil 20 is electrically connected to the first elastic member 31a, it is convenient to weld an external circuit to energize the voice coil 20. Such a welding structure can reduce distortion, enhance air compliance, and improve the effect of the overall headphone body.
[0051] 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 support member 50. This connection method between the first magnetic member 12 and the second magnetic member 13 allows the elastic member to be conveniently installed at both ends of the magnetic assembly 10 without affecting the cooperation between the magnetic circuit and the voice coil.
[0052] The first magnetic member 12 is in a ring shape. The second magnetic member 13 is in a T shape, with two opposite sides of the second magnetic member 13 connected to the first magnetic member 12 and the middle connected to the first elastic member 31a.
[0053] Of course, the first magnetic member 12 and the second magnetic member 13 may also adopt other shapes.
[0054] 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 that can generate magnetic attraction with a magnet. For example, the first magnetic member 12 is a magnet, and the second magnetic member 13 is metal iron, or the first magnetic member 12 is 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, and the purpose of generating a magnetic circuit can be achieved.
[0055] 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 located at both ends of the magnetic assembly 10. Of course, it is preferred to select fewer magnetic members to form the magnetic assembly 10, so that the overall connection structure is more stable.
[0056] Furthermore, the magnetic assembly 10 further includes a magnetic conductive member 14 connected to one end of the first magnetic member 12 away from the second magnetic member 13, and the magnetic conductive member 14 is connected to one end of the first magnetic member 12 away from the second magnetic member 13 for magnetic conductivity. The second elastic member 32a is installed at a position close to the magnetic conductive member 14. For example, the magnetic conductive member 14 is a washer.
[0057] The first magnetic member 12 defines a first through hole, the second magnetic member 13 defines a second through hole, and the magnetic conductive member 14 defines a third through hole, wherein the first through hole, the second through hole and the third through hole together form the through hole 120 .
[0058] The function of the voice coil 20 is to cut the magnetic lines of force and generate electromotive force. As long as it can accomplish this function, its shape, structure and material are not limited.
[0059] The voice coil 20 is located in the space surrounded by the first magnetic member 12, the second magnetic member 13 and the supporting member 50, namely the magnetic gap 11. In this way, the entire earphone body forms an integral body, which is convenient for the later installation of the housing.
[0060] The bone conduction 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. This enhances the stability of the electrical connection. The circuit board 21 may be a PCB board, or a plastic board or metal plate with a built-in circuit, etc., which can play the role of electrically connecting the voice coil 20, the first elastic member 31a or the second elastic member 32a.
[0061] When the voice coil 20 is electrically connected to the first elastic member 31 a through the circuit board 21 , the circuit board 21 is connected to the first elastic member 31 a through the conductive component, and the conductive component can be pulled to the first elastic member 31 a through the through hole 120 .
[0062] The first elastic member 31a and the second elastic member 32a are both steel sheets or plastics with built-in circuits. Alternatively, the first elastic member 31a and the second elastic member 32a can also be conductive metal sheets, both of which can play a role in transmitting vibration.
[0063] The first elastic member 31a is installed at one end of the second magnetic member 13 away from the first magnetic member 12, and the second elastic member 32a is installed near one end of the first magnetic member 12 away from the second magnetic member 13 or one end of the magnetic conductive member 14 away from the second magnetic member 13. Such a structure allows the voice coil 20 to have a large vibration space and can ensure the stability of the overall vibration of the magnetic circuit.
[0064] In this embodiment, there is a gap between the second elastic member 32a and the circuit board 21. This leaves space for the vibration of the second elastic member 32a, improves the sound quality of the earphone body, and reduces distortion.
[0065] When the voice coil 20 is electrically connected to any one of the first elastic member 31a or the second elastic member 32a, a pad is provided on the electrically connected first elastic member 31a or the second elastic member 32a to facilitate electrical connection with an external circuit, so that the entire earphone body is electrically conductive.
[0066] In order to facilitate the connection of the external circuit, when the second elastic member 32a is electrically connected to the voice coil 20, the circuit of the second elastic member 32a can also be led to the first elastic member 31a, and a pad or a circuit board is provided on the first elastic member 31a to connect the external circuit. For example, the circuit of the second elastic member 32a is wound around the first elastic member 31a through the support member 50.
[0067] The conductive member 40 is a component for vibrating and transmitting sound, and is connected to the second elastic member 32a. When the second elastic member 32a 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.
[0068] The function of the support component 50 is to support the first elastic member 31a and the second elastic member 32a, and provide support so that they will not be greatly deformed, so that the magnetic circuit system can generate vibration together to ensure the stability of the structure. The support component 50 can be made of materials such as plastic, iron, and low-carbon steel. The connection between the support component 50 and the first elastic member 31a and the second elastic member 32a can be achieved by gluing, connecting parts, etc.
[0069] The overall shape of the supporting component 50 is annular, so as to facilitate cooperation with the above structure.
[0070] Furthermore, the bone conduction earphone body 100 further includes a conductive block 60, which connects the conductive member 40, the second elastic member 32a and the circuit board 21, and the second elastic member 32a is electrically connected to the circuit board 21 through the conductive block 60. The conductive block 60 allows the second elastic member 32a to be electrically connected to the circuit board 21 without contact.
[0071] The conductive block 60 can be configured as required, and can be conductive itself or by configuring 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 respectively connected to the second elastic member 32a, the circuit board 21, and the conductive member 40. Alternatively, the conductive block 60 is made of a conductive material, and the conductive block 60 is directly in electrical contact with the second elastic member 32a and the circuit board 21.
[0072] In this embodiment, the conductive element is a conductive spring.
[0073] The first magnetic component 201 can be installed on the housing 204 , or can be directly a metal component as the housing of the bone conduction speaker 203 .
[0074] For example, the second magnetic member 202 is a magnet, and the housing 204 is a metal housing that can be magnetically attracted to the second magnetic member 202, and the metal housing forms the first magnetic member 201. The metal housing is, for example, an iron housing.
[0075] Please refer to Figures 1 to 4 For another example, the shell 204 is a soft shell. When the soft shell contacts the human ear, the comfort of the human ear can be ensured. At this time, the first magnetic component 201 is installed on the shell 204, the first magnetic component 201 is a magnet, the second magnetic component 202 is a magnet or a metal that can be magnetically attracted to the first magnetic component 201, or the second magnetic component 202 is a magnet, and the first magnetic component 201 is a magnet or a metal that can be magnetically attracted to the second magnetic component 202. The soft shell is, for example, a silicone shell.
[0076] In this embodiment, the second magnetic member 202 includes a magnetic body and a flexible shell covering the outside of the magnetic body. In this way, the magnetic body in the second magnetic member 202 is not exposed to the outside, the appearance is better, and its function is not affected. The flexible shell is, for example, a silicone shell, a plastic shell, etc.
[0077] Furthermore, the earphone 100 further includes a conductive element 205 and a control component 206, and the control component 206 is electrically connected to the bone conduction speaker 203 through the conductive element 205. In this way, the operation of the bone conduction speaker 203 can be controlled by the control component 206. Figure 2 For example, the control component 206 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 can be, for example, a battery, a charger, etc., preferably a small battery. The switch module 209 can control the opening and closing of the bone conduction speaker 203. In this way, the operation of the bone conduction speaker 203 can be controlled without removing the bone conduction speaker 203. The circuit module 208 is electrically connected to the circuit board 21.
[0078] The switch module 209 is provided with a switch button 2090 , and the bone conduction speaker 203 can be controlled by pressing the switch button 2090 .
[0079] Please refer to Figure 5 Furthermore, the control component 206 further includes a volume adjustment module 210 electrically connected to the circuit module 208. The volume adjustment module 210 can control the volume of the bone conduction speaker 203.
[0080] Please refer to Figures 1 to 4 The volume adjustment module 210 is provided with a volume button 2100, through which the volume can be adjusted.
[0081] Furthermore, the control component 206 further includes an insulating shell 211 covering the power supply module 207, the circuit module 208, the switch module 209 and the volume adjustment module 210, and the switch button and the volume button both extend out of the insulating shell 211. The insulating shell 211 covers the outside of the circuit component, thereby protecting the human body from the influence of the circuit component.
[0082] Furthermore, the conductive element 205 includes an element body 212 and an insulating sleeve 213 covering the outside of the element body 212, and the control component 206 is electrically connected to the bone conduction speaker 203 through the element body 212. The insulating sleeve 213 protects the human body from the influence of the element body 212.
[0083] Please refer to Figure 8 and Fig. 9 The shapes of the control component 206 and the conductive element 205 may be the same or different. The insulating shell 211 and the insulating sleeve 213 may be integrated.

The connecting portion 700 is used to fix the second magnetic member 202, so that the second magnetic member 202 and the bone conduction earphone body 200 are integrated to prevent the second magnetic member 202 from being lost. The connecting portion 700 is made of a soft material to facilitate its bending. For example, it is made of soft rubber, metal and other materials.

The second elastic component 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 provided at the outer edge of the second elastic component 32b, so that a vibration space is formed between the protrusion 33 and the voice coil 20. In this way, enough space is left for the magnetic circuit system to vibrate.
[0093] The shape of the protrusion 33 is arc or square, the number of the protrusion 33 is one, two or more, and the multiple protrusions 33 can be arranged continuously or at intervals. The size of the protrusion 33 can also be set as required.
[0094] For example, a plurality of arc-shaped protrusions 33 are arranged at intervals, and one or more of the protrusions 33 correspond to the position of the voice coil 20 .

[0104] When working, the voice coil 502 is energized, and vibrates in the magnetic field generated by the magnetic component 501, so that the vibration plate 503 and the conductive member 504 vibrate accordingly. Since the magnetic component 501 includes at least two combined magnetic members, when the volume of the entire earphone body is reduced, the volume of the magnetic component 501 can remain unchanged or be enlarged, and the volume of the magnetic component 501 is less affected. Therefore, when the volume of the entire earphone body is reduced, the transmission effect of the sound wave is not affected, thereby effectively ensuring the sound quality.
[0105] The magnetic assembly 501 includes a first magnetic member 506 and a second magnetic member 507. A through hole 508 is provided in the middle of the first magnetic member 506. The second magnetic member 507 is installed in the through hole 508, so that a magnetic gap 509 is formed between the 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. When the voice coil 502 is installed in the magnetic gap 509, the magnetic flux lines can be cut more strongly, thereby ensuring better sound quality.
[0106] The shapes of the first magnetic component 506 and the second magnetic component 507 can be set as needed.
[0107] In this embodiment, the first magnetic member 506 is in a ring shape, so as to form a through hole 508 in the middle of the first magnetic member 506, and the second magnetic member 507 is in a block shape, which is installed in the through hole 508 and does not contact the side wall of the first magnetic member 506, thereby forming the above-mentioned magnetic gap 509. The second magnetic member 507 can be in a ring shape, a block shape, a strip shape, etc., and it can cooperate with the first magnetic member 506.
[0108] 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 that can generate magnetic attraction with a magnet. For example, the first magnetic member 506 is a magnet, and the second magnetic member 507 is metal iron, or the first magnetic member 506 is 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, all of which can achieve the purpose of generating a magnetic circuit.
[0109] Of course, the first magnetic member 506 and the second magnetic member 507 may also adopt other shapes.
[0110] Of course, the magnetic assembly 501 may also include three or more magnetic components. It is preferred to select fewer magnetic components to form the magnetic assembly 501, so that the overall connection structure is more stable.
[0111] Furthermore, the magnetic assembly 501 further includes a first magnetic conductive member 510 connected to one end of the first magnetic member 506 close to the vibrating member 503 and a second magnetic conductive member 511 connected to one 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 play a role of magnetic conductivity. The first magnetic conductive member 510 and the second magnetic conductive member 511 can be a metal that generates magnetic attraction, or a magnet, preferably a metal that generates magnetic attraction, such as iron metal.
[0112] Furthermore, the magnetic assembly 10 further includes a third magnetic conductive member 513, which is mounted on the ends of the first magnetic member 506 and the second magnetic member 507 away from the vibrating member 503. The third magnetic conductive member 513 can be used to mount the first magnetic member 506 and the second magnetic member 507, and can also be used to guide magnetism. The third magnetic conductive member 513 can be a metal that generates magnetic attraction, or a magnet, preferably a metal that cooperates with a magnet, such as iron.
[0113] The third magnetic conductive member 513 and the second magnetic member 507 can be separately arranged or integrally arranged. After being integrally arranged, a T-shaped iron is formed, which is easier to install. When the third magnetic conductive member 17 and the second magnetic member 12 form a T-shaped iron, since both the third magnetic conductive member 17 and the second magnetic member 12 can conduct magnetism, the second magnetic conductive member 16 does not need to be removed.
[0114] The voice coil 502 is installed in the magnetic gap 509 of the magnetic assembly 501. The function of the voice coil 502 is to cut the magnetic lines of force and generate electromotive force. As long as it can achieve this function, its shape, structure and material are not limited.
[0115] In this embodiment, the voice coil 502 is in a ring shape and is directly installed in the annular magnetic gap 509 mentioned above.
[0116] The vibrator 503 is installed at one end close to the magnetic component 501. The vibrator 503 is connected to the voice coil 502 and is electrically connected to the voice coil 502, thereby electrically connecting the entire earphone body. When the voice coil 502 vibrates, the vibrator 503 vibrates accordingly, thereby transmitting the vibration to the conductive member 504.
[0117] In this embodiment, a pad is provided at the outer end of the vibrator 503, and an external circuit is connected through the pad, so that the circuit of the entire earphone body is turned on. Of course, the vibrator 503 can also turn on the external circuit in other ways.
[0118] In this embodiment, the vibrating member 503 is a vibrating plate, which has a smaller thickness and is more convenient for transmitting vibration.
[0119] In this embodiment, the vibrator 503 is made of a hard material and has a built-in 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 vibrator 503 and the vibrator 503 is made of a hard material, the stability when connected to the voice coil can be ensured, and the stability when the vibrator 503 and the voice coil 502 vibrate can be ensured. In contrast, a general soft vibrator needs to rely on auxiliary components to connect to the voice coil 502, or a gap is set between the voice coil 502 and the vibrator 503.
[0120] For example, the vibration 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 vibration element 503 .
[0121] Of course, the vibrating member 503 can also be made of other elastic elements, such as ordinary metal sheets, but the stability effect is not as good as that of hard materials.
[0122] The conductive element 504 is connected to the vibrating element 503 and is a component for vibrating and transmitting sound. When the vibrating element 503 vibrates, the vibration is transmitted to the conductive element 504. The conductive element 504 can generally be a piezoelectric ceramic sheet, a PC conductive sheet, or other conductive elements.
[0123] In this embodiment, the conductive element 504 is connected to a side of the vibrating element 503 away from the magnetic component 501 .
[0124] The function of the support component 505 is to support the vibrating component 503 and the magnetic component 501, and to provide support to make the installation structure of the vibrating component 503 and the magnetic component 501 more stable. The support component 505 can be made of materials such as plastic, iron, and low-carbon steel. The connection between the support component 505 and the vibrating component 503 and the magnetic component 501 can be achieved by gluing, connecting with a connector, and the like.
[0125] The supporting member 505 can be made of metal, plastic or other hard materials.
[0126] The support member 505 may be supported only between the magnetic assembly 501 and the vibrator 503 , or may cover both sides of the magnetic assembly 501 , or may only cover one side of the magnetic assembly 501 . In this embodiment, the support member 505 is ring-shaped and is installed between the magnetic assembly 501 and the vibrator 503 .
[0127] In other embodiments, the support member 505 is annular, 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 annular, covering both sides of the magnetic assembly 501.
[0128] In this embodiment, the bone conduction speaker 800 further includes a circuit board 512, which is mounted on a side of the third magnetic conductive member 513 away from the magnetic assembly 501, and the vibrating member 503 is electrically connected to the circuit board 512 through a conductive member. The circuit board 512 can be more conveniently connected to an external circuit. In one embodiment, a first wire groove is provided on the outside of the supporting member 505, a second wire groove is provided on the outside of the first magnetic conductive member 510, and a third wire groove is provided on the outside of the first magnetic member 506. The conductive member is guided to the circuit board 512 by the first wire groove, the second wire groove and the third wire groove in sequence. The provision of the wire groove can facilitate the guiding of the conductive member to the circuit board 512 on the one hand, and can hide the conductive member and prevent the conductive member from being exposed on the other hand, so that the volume of the shell covering the entire earphone body can also be reduced, which is convenient for preparing a miniature earphone body. The conductive member is, for example, a wire, a conductive sheet, and the like.
[0129] When the support component 505 is wrapped around both sides of the magnetic assembly 501 , a wire groove may be opened in the support component 505 , and the conductive member may extend from the wire groove of the support component 505 to be connected to the circuit board 512 .
