[0005] In the present application, the bone conduction component is located at the free end of the rotating part. When the bone conduction component contacts the user's head, such as the back of the auricle, the vibration can be directly transmitted to the user through the contact position, avoiding the problem of sound leakage in the process of transmitting sound information through the air. In addition, the bone conduction component is arranged at one end of the rotating part, which occupies a small space and has a beautiful appearance without being obtrusive; and when the user does not use the bone conduction function, the rotating part and the supporting part can serve as temples, which is similar to the appearance of existing glasses, making it easier for users to use and wear in daily life.

[0006] In addition, the bone conduction device may have multiple gears corresponding to different angles.

[0007] In addition, the angle between the rotating part and the supporting part is different, and the contact surface area and contact pressure between the bone conduction part and the back of the auricle are also different.

The mating surface is used to cooperate with the button, and the button is used to move along a first direction under the action of an external force, and the first direction is perpendicular to the sliding direction of the slider.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more than two.

[0051] The embodiment of the present application is described by taking the electronic device being smart glasses as an example.

[0052] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of the electronic device 100 provided by the present application in some embodiments. For example, the electronic device 100 may include a frame 10, temples 20, and a bone conduction device 30. When the user wears the electronic device 100, the temples 20 are arranged in the space behind the auricle, and play a role in supporting the frame 10 by cooperating with the ear.

[0053] Exemplarily, the electronic device 100 may further include a battery and a control center (not shown). The battery may be used to power the bone conduction device. The control center may be used to control the bone conduction device to transmit sound information through the contact part with the user. The control center may include at least one processor and at least one memory, the memory is used to store instructions, and the processor is used to execute instructions to control the electronic device 100 to perform corresponding operations.

[0054] Exemplarily, the bone conduction device 30 may include a support portion 31, a rotating portion 32, and a rotating mechanism 33. The rotating mechanism 33 connects the support portion 31 and the rotating portion 32. The rotating mechanism 33 can move so that the rotating portion 32 rotates relative to the support portion 31.

[0055] For example, when the user wears the bone conduction device 30, the bone conduction device 30 can contact the user's temple, the front side of the tragus, or the back side of the auricle, and transmit sound information through the above contact positions, which makes the use more flexible. When the bone conduction device 30 transmits sound information, it can generate vibrations according to the sound information and directly transmit the vibrations to the user's auditory nerves through the contact parts, avoiding energy loss caused by vibration transmission in the air. In addition, it also avoids the influence of the external environment on the sound waves and avoids the attenuation of the timbre.

[0056] Exemplarily, the bone conduction device 30 can be used as the temple 20. The support portion 31 can be fixedly connected to the frame 10. When the user wears the electronic device 100, that is, the smart glasses, the support portion 31 can be mounted on the user's head to support the frame 10. At this time, the bone conduction device 30 can simultaneously support the frame 10 and transmit sound information. In some other embodiments, the bone conduction device 30 can also be used as a part of the temple 20. Exemplarily, the bone conduction device 30 can be connected to the temple 20 and move relative to the temple 20. At this time, the bone conduction device 30 can contact different positions of the user's head, and the user can adjust the contact position according to habits and preferences to ensure the experience of the bone conduction device 30. This application is described by taking the bone conduction device 30 as the temple 20 as an example.

[0057] Please also read Figure 2 and Figure 3 , Figure 2 yes Figure 1 The partial structural diagram of the bone conduction device 30 is shown in FIG. Figure 3 yes Figure 2 The bone conduction device 30 is shown as a schematic diagram of the internal structure cut along AA.

[0058] Exemplarily, the rotating portion 32 includes a rotating end 3201 and a free end 3202 that are arranged opposite to each other, and the rotating end 3201 is arranged near the support portion 31 relative to the free end 3202. The rotating portion 32 may include a plurality of gear shift blocks 321, and the plurality of gear shift blocks 321 may be located at the rotating end 3201. An angle α is formed between the rotating portion 32 and the support portion 31. The angle α between the rotating portion 32 and the support portion 31 is defined as the angle α between the lower side of the rotating portion 32 and the lower side of the support portion 31. In the embodiment of the present application, when the user wears the electronic device 100, the direction close to the ear is defined as "down". It can be understood that the directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "top", etc., are only referenced to the directions of the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0059] Exemplarily, the rotating part 32 may also include a bone conduction component 322, which is located at the free end 3202 of the rotating part 31. The control center can control the bone conduction component 322 to generate vibrations according to the sound information. When the bone conduction component 322 contacts the user's head, such as the back of the auricle, the vibration can be directly transmitted to the user through the contact position, avoiding the problem of sound leakage in the process of transmitting sound information through the air. In addition, the bone conduction component 322 is arranged at one end of the rotating part 32, which occupies a small space and has a beautiful appearance without being obtrusive; and when the user does not use the bone conduction function, the rotating part 32 and the supporting part 31 can act as temples, which are similar to the appearance of existing glasses, and are convenient for users to use and wear in daily life.

[0060] Exemplarily, the bone conduction device 30 may have multiple gears, corresponding to different angles α. In the present application, the user applies force on the free end 3202 to make the rotating end 3201 rotate relative to the support portion 31, so that the bone conduction member 322 contacts the user, thereby being able to receive sound signals through the contact position. Moreover, the angle α between the rotating portion 32 and the support portion 31 is different, and the area of ​​the contact surface of the bone conduction member 322 and the rear side of the auricle, as well as the contact pressure are also different. Therefore, the user can change the angle α between the rotating portion 32 and the support portion 31 by applying different forces to the rotating portion 32, and adjust the gear of the bone conduction device 30. The user can select a suitable gear according to the head shape, adjust the contact pressure and / or select different contact positions, so as to obtain a suitable audio experience, ensure the transmission performance of sound information, and improve the wearing comfort. In addition, the angle α of the present application has a wide range of selection, for example, the angle α can be in the range of 0° to 180°. Therefore, the contact pressure of the bone conduction device 30 of the present application has a wide adjustable range, and can meet the diverse needs of users with various head shapes.

[0061] Understandably, the bone conduction component 322 may also be located at other positions of the rotating portion 32. The bone conduction component 322 may be a fixed component, that is, the bone conduction component 322 is fixed at the position of the rotating portion 32; or a movable component, that is, the bone conduction component 322 may move along the extension direction of the rotating portion 32 to adjust the contact position with the rear side of the auricle.

[0062] Exemplarily, the rotating mechanism 33 may include a slider 331 and an elastic member 332. The slider 331 may be slidably mounted on the support portion 31, the elastic member 332 may be mounted on the support portion 31, and both ends of the elastic member 332 may be connected to the support portion 31 and the slider 331, respectively. In this embodiment, the slider 331 may slide along the extension direction of the support portion 31. In some other embodiments, the slider 331 may also slide along a direction having a certain angle with the extension direction of the support portion 31, which is not limited in this application.

[0063] In this embodiment, the elastic member 332 is in a deformed state, and the elastic force of the elastic member 332 pushes the slider 331 against the multiple gear shifting blocks 321 to engage with the multiple gear shifting blocks 321 to achieve a locking effect. When the free end 3202 is subjected to force, the multiple gear shifting blocks 321 of the rotating end 3201 push the slider 331 away, and the rotating end 3201 rotates relative to the support portion 31, and the angle α between the rotating portion 32 and the support portion 31 changes. The slider 331 engages with the multiple gear shifting blocks 321 again under the elastic force of the elastic member 332, and the gear position of the bone conduction device 30 is changed.

[0064] Exemplarily, the rotating mechanism 33 may further include a rotating shaft 333. The supporting portion 31 may be rotatably connected to the rotating portion 32 via the rotating shaft 333. A plurality of gear shifting blocks 321 may be disposed at intervals on the periphery of the rotating shaft 333.

[0065] Exemplarily, the rotating mechanism 33 may further include a plurality of auxiliary shift blocks 321a, the plurality of auxiliary shift blocks 321a are fixed to the rotating portion 32, the plurality of auxiliary shift blocks 321a are engaged with the slider 331, the plurality of auxiliary shift blocks 321a are arranged opposite to the plurality of shift blocks 321, and rotate coaxially with the plurality of shift blocks 321. The thickness of the auxiliary shift block 321a may be smaller than the shift block 321. In this embodiment, the thickness of the shift block 321 may also be smaller than the thickness in the embodiment including a single group of shift blocks 321. In the present application, two sets of gear shift blocks (gear shift block 321 and auxiliary gear shift block 321a) arranged opposite to each other are used instead of a thicker set of gear shift blocks (gear shift block 321 or auxiliary gear shift block 321a). This can reduce the thickness of the gear shift block 321 and / or the auxiliary gear shift block 321a while ensuring the mechanical strength and rotational stability of the bone conduction device 30, thereby reducing costs, reducing the weight of the bone conduction device 30, and making it easier for users to wear.

[0066] For example, please refer to Figure 2 and Figure 3 The slider 331 may include a first protrusion 331a and a second protrusion 331b that are arranged opposite to each other and spaced apart, and the first protrusion 331a and the second protrusion 331b are respectively engaged with the plurality of gear shift blocks 321 and the plurality of auxiliary gear shift blocks 321a. The slider 331 also includes a sliding body 331c, the sliding body 331c is fixedly connected to the first protrusion 331a and the second protrusion 331b, and the elastic member 332 is connected to the sliding body 331c.

[0067] Exemplarily, the thickness of the first protrusion 331a and the second protrusion 331b may be less than the thickness of the slider 331. In the present application, two sets of protrusions with smaller thickness are used to replace the slider, which can reduce the thickness while ensuring the mechanical strength and rotational stability of the bone conduction device, thereby reducing the cost and weight of the bone conduction device, making it easier for users to wear.

[0068] Exemplarily, the shift block 321 can be made of a rigid material such as metal or plastic to ensure the mechanical strength of the rotating mechanism 33. The shift block 321 can also be made of a surface-strengthened material, such as nitriding or chrome plating the metal material, to increase the strength of the contact surface and extend the service life of the rotating mechanism 33.

[0069] Exemplarily, the auxiliary gear shift block 321a can be made of the same material as the gear shift block 321, or can be made of a different material, which is not limited in the present application, as long as the mechanical strength of the rotating mechanism 33 can be guaranteed.

[0070] Exemplarily, the rotating part 32 may include a rigid connector 3203 and an elastic connector 3204. The rigid connector 3203 is located at the rotating end 3201 and is fixedly connected to the elastic connector 3204. The rigid connector 3203 may be made of stainless steel, aluminum, or other materials to ensure the strength of the rotating part 32. The elastic connector 3204 is located at the free end 3202 and is fixedly connected to the bone conduction component 322. The elastic connector 3204 can be elastically deformed and absorb part of the contact pressure through deformation, which is used to fine-tune the contact pressure after the gear is locked and ensure the stability of the contact pressure.

[0071] For example, the elastic connector 3204 may be made of a material such as soft rubber. An elastic support member (not shown) may be provided inside the elastic connector 3204, and the elastic support member may be a metal member or a plastic member that can be elastically deformed, such as a spring, a plastic sheet, a memory alloy, etc., to improve the elasticity of the soft rubber material. In some other embodiments, the elastic connector 3204 may also be provided with only an elastic support member, which is not limited in the present application.

[0072] Please also read Figure 4 and Figure 5 , Figure 4 yes Figure 3 The bone conduction device 30 is in the first gear position. Figure 5 yes Figure 3 The bone conduction device 30 is shown in a schematic diagram when it is in the maximum gear position.

[0073] Exemplarily, the bone conduction device 30 may have multiple gears, including the 1st gear, the 2nd gear, ... the Nth gear, where N is an integer greater than or equal to 1. When the slider 331 is engaged between the Nth gear shift block 321 and the N+1th gear shift block 321, there is an Nth angle αN between the rotating portion 32 and the supporting portion 31, and the bone conduction device 30 is in the Nth gear. This application takes N as 7 as an example for explanation, that is, in this embodiment, the bone conduction device 30 may have 7 gears. It can be understood that N may also be any integer such as 2, 5, 8, etc., and the number of gears can be set according to the application scenario, which is not limited in this application.

[0074] For example, Figure 4 The slider 331 shown is engaged between the first gear shift block 3211 and the second gear shift block 3212. At this time, the bone conduction device 30 is in the first gear. When the bone conduction device 30 is in the first gear, there is a first angle α1 between the rotating part 32 and the supporting part 31. The first angle α can be approximately 180°, which is convenient for the user to set the bone conduction device 30 on the back side of the auricle. In some other embodiments, the first angle α can also have a slight deviation from 180°, such as 165°, 177° or 185°, etc. In this case, the bone conduction device 30 is also considered to be in the first gear.

[0075] For example, Figure 5 The meshing state of the slider 331 and the gear shift block 321 shown is the maximum gear of the bone conduction device 30. In this embodiment, the maximum gear is the 7th gear. When the bone conduction device 30 is in the 7th gear, there is a limit angle α7 between the rotating part 32 and the supporting part 31. The limit angle α7 is the minimum angle formed between the rotating part 32 and the supporting part 31 during the rotation of the rotating part 32 relative to the supporting part 31. The 7th gear is the limit condition set by the user according to the application environment. When the bone conduction device 30 is in the 7th gear, the free end 3202 is not able to rotate the rotating part 32 relative to the supporting part 31. The user sets the limit angle α7 to avoid the user's operating error or the impact of foreign objects, which causes the bone conduction component 322 to over-press the back of the auricle and cause damage to the human body.

[0076] For example, the limit angle α7 may be approximately 75°. In some other embodiments, the limit angle α7 may also be slightly different from 75°, such as 70°, 87° or 95°, etc. In this case, the bone conduction device 30 is also considered to be in the seventh gear. It is understandable that the limit angle α7 can be set according to different application scenarios, and this application does not limit this.

[0077] Exemplarily, the bone conduction device 30 may also have a plurality of intermediate gears between the first gear and the seventh gear, such as the second gear. When the bone conduction device 30 is in the second gear, there is a second angle α2 (not shown) between the rotating portion 32 and the supporting portion 31. At this time, the rotating portion 32 is bent relative to the supporting portion 31 so that the bone conduction member 322 contacts the back side of the auricle to achieve the transmission of sound information. The angle α of the intermediate gear may be greater than the limit angle α7 and less than the first angle α1.

[0078] In the present application, when the user wears the bone conduction device 30, the bone conduction device 30 is generally in the first gear. Afterwards, the user can apply force to the rotating part 32 to rotate the rotating part 32 relative to the supporting part 31 until the bone conduction member 322 contacts the back of the auricle. At this time, the bone conduction device 30 is in the first gear or an intermediate gear between the first gear and the seventh gear or the seventh gear. The user can select different gears according to the head shape to obtain a suitable audio experience and improve the wearing comfort.

[0079] Exemplarily, the intervals between the multiple gear shift blocks 321 are uniform, so that parameters such as contact area and contact pressure can change linearly with the change of gear, which is convenient for user control. For example, the difference between the Nth angle αN and the N+1th angle αN+1 can be 10°, 15°, 30°, etc., which is not limited in this application. In some other embodiments, the difference between the Nth angle α and the N+1th angle α can also be unequal to provide a special audio experience, which can be set according to the application scenario, which is not limited in this application.

[0080] For example, please refer to Figure 4 and Figure 6 , Figure 6 yes Figure 4 Schematic diagram of a partial structure of the bone conduction device 30 shown. Each gear shift block 321 may adopt a ratchet structure, that is, the gear shift block 321 is an asymmetric structure. The outer surface of the gear shift block 321 may include two side surfaces arranged opposite to each other. The two side surfaces of the gear shift block 321 may be located on the same side of the radial line or one of the side surfaces may coincide with the radial line, so that the gear shift block 321 can rotate unidirectionally relative to the slider 331. The radial line is the line connecting the highest point 3210 of the gear shift block 321 and the rotation center. The rotation center may be the center of the rotating shaft 333; the highest point 3210 is the point of the gear shift block 321 farthest from the rotation center.

[0081] Exemplarily, the shift block 321 can rotate counterclockwise or clockwise relative to the slider 331. The present embodiment of the application is described by taking the clockwise rotation of the shift block 321 relative to the slider 331 as an example.

[0082] Specifically, the gear shift block 321 can be located on the clockwise side of the radial line in the circumferential direction of the rotating shaft 333, so that the gear shift block 321 can rotate unidirectionally relative to the slider 331, that is, the gear shift block 321 can rotate clockwise relative to the slider 331, but cannot rotate counterclockwise relative to the slider 331. The user can adjust the bone conduction device 30 to a suitable gear according to the wearing experience. The unidirectional rotation of the gear shift block 321 can lock the current gear, ensure the stability of the contact pressure between the bone conduction device 30 and the back of the auricle, and ensure the audio experience of the product.

[0083] It is understandable that in some other embodiments, the unidirectional rotation of the gear shift block 321 relative to the slider 331 may also mean that the gear shift block 321 can rotate counterclockwise relative to the slider 331 but cannot rotate clockwise, and this application does not limit this. In this embodiment, the structure of the gear shift block 321 is adaptively modified according to the rotation direction, that is, the gear shift block 321 is located on the counterclockwise side of the radial line in the circumferential direction of the rotating shaft, and this application does not elaborate on this.

[0084] Please also read Figure 4and Figure 7 , Figure 7 yes Figure 4 The force analysis diagram of the bone conduction device 30 is shown in FIG. Figure 7 FIG. 3 is a schematic diagram of force analysis when the rotating part 32 is subjected to a clockwise force. Figure 4 In the first gear position shown, the slider 331 is engaged between the first gear shift block 3211 and the second gear shift block 3212. Afterwards, the user shifts the rotating portion 32 toward the direction close to the support portion 31, and the plurality of gear shift blocks 321 rotate in the clockwise direction driven by the rotating portion 32.

[0085] As the second gear shift block 3212 rotates, the second gear shift block 3212 first moves toward the support portion 31 and provides a first force Z1 inclined upward to the slider 331. The first force Z1 can be decomposed into a first horizontal force component X1 and a first vertical force component Y1, wherein the first horizontal force component X1 can push the slider 331 to move toward the support portion 31 and compress the elastic member 332, causing the elastic member 332 to elastically deform and generate an elastic force. The second gear shift block 3212 pushes the slider 331 away and continues to rotate, and the slider 331 engages with the multiple gear shift blocks 321 again under the elastic force of the elastic member 332, thereby realizing the change of the gear of the bone conduction device 30.

[0086] In this embodiment, when the shift block 321 rotates in the clockwise direction, the slider 331 contacts the side of the shift block 321, and the shift block 321 provides a first horizontal component force X1 to the slider 331 to push the slider 331 to move toward the support portion 31, thereby providing space for the rotation of the shift block 321, so that the shift block 321 can rotate from the lower side of the slider 331 to the upper side of the slider 331.

[0087] Please also read Figure 7 and Figure 8 , Figure 8 yes Figure 4 The force analysis diagram of the bone conduction device 30 in other force conditions is shown. Figure 8 The rotating part 32 is subjected to Figure 6 Schematic diagram of force analysis when the force is opposite to the force in the direction of action, that is, the force is counterclockwise.

[0088] In the present application, the ratchet structure of the shift block 321 prevents the shift block 321 from rotating counterclockwise relative to the slider 331 .

[0089] Specifically, when the shift block 321 rotates in the counterclockwise direction, the slider 331 contacts the tooth top of the shift block 321, and the shift block 321 provides a second force Z2 to the slider 331. The second force Z2 can be decomposed into a second horizontal force component X2 and a second vertical force component Y2. The second horizontal force component X2 is opposite to the first horizontal force component X1, and the second vertical force component Y2 is opposite to the first vertical force component Y1. That is, the second force Z2 does not have a horizontal force component or has a second horizontal force component X2 opposite to the first horizontal force component X1. The second force Z2 does not have the first horizontal force component X1, and cannot push the slider 331 to move toward the support portion 31, providing space for the rotation of the shift block 321, thereby blocking the rotation of the shift block 321. Therefore, the shift block 321 cannot rotate in the counterclockwise direction.

[0090] See also Figure 6 Exemplarily, the two side surfaces of the shift shift block 321 may include a first side surface and a second side surface, wherein the first side surface is away from a radial line relative to the second side surface.

[0091] In this embodiment, the slider 331 may include an inclined surface, and the inclined surface may be inclined relative to the sliding direction of the slider 331. The inclined surface of the slider 331 may be used to contact the first side surface of the shift block 321, so as to make the force more uniform, ensure the stability of the contact pressure, and improve the stability of the sound information transmission performance; and reduce the local pressure on the contact surface, avoid the occurrence of local cracks, and affect the service life of the shift block 321 and the slider 331.

[0092] Exemplarily, the slider 331 may include a plane, which is inclined relative to the inclined plane, that is, there is an angle between the plane and the inclined plane. The plane of the slider 331 can be used to contact the top of the gear shift block 321 to provide stable support for the gear shift block 321, ensure the stability of the contact pressure, and improve the stability of the sound information transmission performance.

[0093] Please also read Figure 3 and Fig. 9 , Fig. 9 yes Figure 3 Schematic diagram of a partial structure of the bone conduction device 30 shown. Exemplarily, the bone conduction device 30 may further include a return member 34. The gear shift block 321 rotates unidirectionally relative to the slider 331, that is, the rotating part 32 moves relative to the supporting part 31, and the user cannot increase the angle α between the rotating part 32 and the supporting part 31 by shifting the rotating part 32 in the opposite direction. The return member 34 can be installed on the supporting part 31 and can move relative to the supporting part 31, and is used to control the sliding of the slider 331 under the control of an external force to release the meshing state of the slider 331 and the plurality of gear shift blocks 321, thereby releasing the gear lock, so that the user can adjust the contact pressure, or release the wearing state of the bone conduction device 30, and remove the bone conduction device 30 from the head.

[0094] Please also read Figure 2 and Figure 8 . Exemplarily, the return member 34 may include a button 341, and the button 341 may cooperate with the inclined surface of the slider 331. Specifically, the sliding body 331c of the slider 331 may include a mating surface. The mating surface is inclined relative to the sliding direction of the slider 331. The mating surface is used to cooperate with the button 341 so that the force applied by the button 341 to the slider 331 is more uniform, so that the sliding process of the slider 331 is smoother, so as to provide stable support for the gear shift block, ensure the stability of the contact pressure, and improve the stability of the sound information transmission performance.

[0095] Exemplarily, the button 341 can move in a first direction (not shown), which can be perpendicular to the sliding direction of the slider 331, so as to push the slider 331 to move toward the support portion 31 and away from the gear shift block 321, thereby providing space for the gear shift block 321 to rotate, so that the gear shift block 321 can rotate in the opposite direction to release the gear lock.

[0096] Exemplarily, the button 341 may be located between the first protrusion 331a and the second protrusion 331b, and the first protrusion 331a and the second protrusion 331b may limit the movement range of the button 341, ensure the stability of the contact pressure, and improve the stability of the sound information transmission performance. It is understandable that the first direction may be any direction perpendicular to the sliding direction of the slider 331, as long as the button 341 moves in the gap between the first protrusion 331a and the second protrusion 331b.

[0097] See also Fig.10 , Fig.10 yes Figure 1 The bone conduction device 30 is a schematic diagram of the structure of some embodiments thereof. In this embodiment, the homing member 34 of the bone conduction device 30 may include a shifting block 342. The shifting block 342 may be slidably mounted on the support portion 31 and fixedly connected to the slider 331. The shifting block 342 may be used to drive the slider 331 to slide under the action of an external force.

[0098] In the present application, the user can toggle the shift block 342 so that the shift block 342 drives the slider 331 to move toward the support portion 31, thereby providing space for the rotation of the rotating portion 32, so that the rotating portion 32 can rotate in both directions to release the gear lock.

[0099] Please also read Fig.11 and Fig.12 , Fig.11 yes Fig.10 The internal schematic diagram of the partial structure of the bone conduction device 30 is shown. Fig.12 yes Fig.10The bone conduction device 30 is shown as a schematic diagram of the interior of the device at another angle. For example, one end of the shift block 342 is located outside the support portion 31, and the other end is fixed to the slider 331. The user moves the shift block 342 by shifting the end surface of the shift block 342 located outside the support portion 31. The shift block 342 may include a plurality of grooves. A plurality of grooves may be provided on the end surface of the shift block 342 located outside the support portion 31 to increase the contact friction, facilitate the user to shift the shift block 342, and enhance the user experience.

[0100] See also Fig.13 , Fig.13 yes Figure 2 FIG. 3 is a schematic diagram of the internal structure of a bone conduction device 30. For example, the bone conduction device 30 may further include a damping member 334, one end of which may be fixed to the support portion 31, and the other end of which may be arranged around the rotating shaft 333 and then fixed to the rotating portion 32. The damping member 334 is compressed as the gear shift block 321 rotates counterclockwise, generating an elastic force, which can provide resistance to the rotation of the gear shift block 321, thereby providing a damping feel for the rotating portion 32.

[0101] For example, the damping member 334 may be a torsion spring structure. When the user presses the button 341 to release the gear lock, the elastic force of the damping member 334 drives the gear shift block 321 to rotate in the opposite direction, so that the rotating part 32 automatically returns to the first gear. Specifically, the damping member 334 may be fixed to the return member 34. Pressing down the return member 34 drives the damping member 334 to rotate, increasing the elastic force of the damping member 334, thereby providing greater power for the reverse rotation of the rotating part 32.

[0102] In some other embodiments, the damping member 334 may also adopt other structures capable of elastic deformation, which is not limited in the present application.

[0103] The above description is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application; in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
