TECHNICAL FIELD

[0001] The utility model relates to earphone equipment technical field, especially a kind of damping rotating device and head-worn earphone. BACKGROUND

[0002] Earphone has been widely applied in people's daily life, which can be used with mobile phone, computer and other electronic devices to provide auditory feast for users. According to the working principle of earphone, it can be generally divided into air-conduction earphone and bone-conduction earphone; according to the way of wearing earphone, it can also be generally divided into head-worn earphone, ear-hanging earphone and in-ear earphone; according to the interaction between earphone and electronic device, it can also be generally divided into wired earphone and wireless earphone. Earphone can accept the electric signal emitted by media player or receiver, and convert it into audible sound wave by loudspeaker close to ear. In the design of head-worn earphone, the connection mode between earphone part and microphone rod directly affects the user experience.

[0003] In the existing head-worn earphone, the rotating connection between earphone part and microphone rod usually adopts simple hinge structure. Although this structure can realize rotation function, it often has problems such as unsmooth rotation, poor damping effect and easy loosening in actual use. Especially in the case of frequent rotation, the hinge structure is easy to wear, which leads to unstable connection between earphone part and microphone rod and affects the user experience. In order to solve the above problems, some improvement schemes are proposed in the prior art, such as using spring or friction plate to increase damping effect. However, these schemes often have complex structure, high manufacturing cost, and still have problems such as uneven damping and unsmooth rotation in actual use. Therefore, there is an urgent need for a damping rotating device with simple structure, good damping effect and long service life. SUMMARY

[0004] Therefore, it is necessary to provide a damping rotating device which can realize stable rotating connection between earphone part and microphone rod, provide good damping effect and improve user experience.

[0005] A damping rotating device, comprising a first shell, a second shell and a buckle damping piece, the first shell is rotatably connected with the second shell, a rotating groove is formed on the first shell, and a wave-shaped clamping structure is formed on the groove wall of the rotating groove in the circumferential direction; the buckle damping piece is outwardly protruded in the radial direction on the circumferential wall to form a buckle protrusion, the buckle damping piece is located in the rotating groove and clamped between the first shell and the second shell, the buckle damping piece is fixedly connected to the second shell, and the buckle protrusion is in clamping cooperation with the wave-shaped clamping structure; the buckle damping piece can rotate relative to the rotating groove to move the buckle protrusion along the arrangement direction of the wave-shaped clamping structure.

[0006] In the damping rotating device provided in the application, the buckle damping member can rotate relative to the rotating groove, so that the buckle convex block moves along the arrangement direction of the wave-shaped clamping tooth structure. The elastic design of the buckle damping member enables it to generate appropriate damping force during rotation. When the buckle convex block slides through each tooth shape of the wave-shaped clamping tooth structure, the buckle damping member will be slightly elastically deformed, thereby generating a damping effect, which not only can provide stable damping force, but also can effectively reduce noise and vibration during rotation. The buckle convex block of the buckle damping member is clamped and matched with the wave-shaped clamping tooth structure of the rotating groove, so as to ensure that the damping effect can be generated during rotation.

[0007] In one embodiment, two buckle convex blocks are arranged on the buckle damping member, and the two buckle convex blocks are located on opposite sides of the buckle damping member. The buckle convex block can improve the reliability and wear resistance of the buckle damping member, so as to ensure the rotating feeling.

[0008] In one embodiment, the contact surface of the wave-shaped clamping tooth structure in contact with the buckle convex block is an arc surface, and the contact surface of the buckle convex block in contact with the wave-shaped clamping tooth structure is an arc surface. The arc surface contact design of the buckle convex block and the wave-shaped clamping tooth structure can reduce the friction resistance of the contact surface and prolong the service life of the device

[0009] In one embodiment, the buckle damping member is a hollow ring structure with elasticity, and the radial length of the buckle convex block along the buckle damping member is greater than the width of the hollow ring structure. The buckle damping member can be elastically deformed during rotation, thereby providing good damping effect and preventing the buckle damping member from being easily damaged by fatigue.

[0010] In one embodiment, a limiting block is arranged on the groove bottom of the rotating groove, and the limiting block abuts against the inner ring surface of the buckle damping member to prevent the buckle damping member from being displaced. The design of the limiting block can ensure that the buckle damping member remains stable during rotation and avoids the damping effect being reduced due to displacement.

[0011] In one embodiment, a limiting groove is arranged in the rotating groove, and a sliding block is arranged on the second shell and slides in the limiting groove to limit the rotation angle of the second shell relative to the first shell. Through the cooperation of the limiting groove and the sliding block, the rotation angle of the second shell relative to the first shell can be accurately controlled, thereby avoiding the inconvenience caused by too large or too small rotation angle.

[0012] In one embodiment, an installation groove is concave in the peripheral wall of the buckle damping member, and the buckle damping member is clamped and fixed to the second shell through the installation groove, so as to rotate synchronously with the second shell. The buckle damping member is clamped and fixed to the second shell through the installation groove, so that the buckle damping member can rotate synchronously with the second shell.

[0013] In one embodiment, the peripheral wall of the latching damper forms two mounting grooves, which are located on opposite sides of the latching damper. Providing two mounting grooves improves the positional stability of the latching damper.

[0014] In one embodiment, the mounting groove is an arc-shaped groove. This ensures a secure connection between the latching damper and the second housing, preventing loosening or detachment during rotation.

[0032] Earphones have been widely used in people's daily life, which can be used with mobile phones, computers and other electronic devices to provide users with a feast of hearing. Among them, according to the working principle of earphones, it can be generally divided into air conduction earphones and bone conduction earphones; according to the way of wearing earphones by users, it can also be generally divided into head-mounted earphones, ear-hanging earphones and in-ear earphones; according to the interaction between earphones and electronic devices, it can also be generally divided into wired earphones and wireless earphones. Earphones can accept the electrical signals emitted by media players or receivers and convert them into audible sound waves using speakers close to the ears. In the design of head-mounted earphones, the connection mode between the earphone part and the microphone rod directly affects the user's experience. The earphone microphone rod is an important component of the head-mounted earphone or headset, and its core functions include fixing the microphone structure, optimizing the sound pickup effect and improving the convenience of use. The earphone microphone rod can fix and support the microphone to ensure the stability of the microphone position, and at the same time, it can also adjust the angle of the microphone, and most microphone rods support multi-angle free rotation, which facilitates users to adjust the direction of the microphone according to the use scene, such as close to the mouth to improve the clarity of the call. In the existing head-mounted earphones, the rotary connection between the earphone part and the microphone rod usually adopts a simple hinge structure. Although this structure can realize the rotation function, in actual use, there are often problems such as unsmooth rotation, poor damping effect and easy loosening. Especially in the case of frequent rotation, the hinge structure is easy to wear out, causing unstable connection between the earphone part and the microphone rod, affecting the user's experience. In order to solve the above problems, some improvement schemes are proposed in the prior art, such as using springs or friction plates to increase the damping effect. However, these schemes often have complex structure, high manufacturing cost, and still have problems such as uneven damping and unsmooth rotation in actual use. Therefore, there is an urgent need for a damping rotary device with simple structure, good damping effect and long service life.

[0033] Reference Figures 1-10To solve the above problems, the damping rotation device 10 provided by the embodiment of the present application comprises a first shell 20, a second shell 30 and a buckle damping part 40. The first shell 20 is rotationally connected with the second shell 30. The first shell 20 is provided with a rotation groove 21. The groove wall of the rotation groove 21 is formed with a wave-shaped clamping tooth structure 211 in the circumferential direction. The buckle damping part 40 is formed with a buckle protrusion 41 outwardly protruding in the radial direction on the circumferential wall. The buckle damping part 40 is located in the rotation groove 21 and is clamped between the first shell 20 and the second shell 30. The buckle damping part 40 is fixedly connected to the second shell 30, and the buckle protrusion 41 is in clamping cooperation with the wave-shaped clamping tooth structure 211. The buckle damping part 40 can rotate relative to the rotation groove 21, so that the buckle protrusion 41 moves along the arrangement direction of the wave-shaped clamping tooth structure.

[0034] In the damping rotation device 10, the first shell 20 and the second shell 30 jointly constitute the shell part of the damping rotation device 10. The first shell 20 is rotationally connected with the second shell 30, so that the second shell 30 can rotate relative to the first shell 20. The position of the second shell 30 relative to the first shell 20 is changed by rotation. In some embodiments, the second shell 30 is a microphone rod. By rotating the microphone rod, the user can adjust the microphone connected with the microphone rod to ensure the stability of the position of the microphone. The first shell 20 is provided with the rotation groove 21. The groove wall of the rotation groove 21 is formed with the wave-shaped clamping tooth structure 211 in the circumferential direction. The wave-shaped clamping tooth structure 211 can increase the friction force during rotation. The buckle damping part 40 is a ring-shaped part with damping properties, which is mainly used to reduce vibration and noise, protect equipment and improve the stability and service life of the equipment. The damping part can effectively absorb and consume vibration energy through its damping properties, thereby reducing the vibration and noise of the equipment. The speed and force of rebound and compression of the damping part when subjected to external force give a damping feel. The damping properties of the damping part will affect the feel. Damping refers to the property of gradually reducing the amplitude of vibration of an object, which is usually caused by friction or internal resistance between the object and the surrounding environment. In the damping part, the damping properties determine the rebound and compression speed after the damping part is subjected to external force. The buckle damping part 40 in the present application has the effect of elastic buffering and can also provide a better damping feel for the user, so that the damping rotation device 10 is not easy to fatigue and damage.

[0035] The buckle damping member 40 is radially outwardly protruded on the peripheral wall to form a buckle protrusion 41 which can be in contact with the wave-shaped tooth structure 211. Specifically, the buckle damping member 40 is located in the rotating groove 21 and is clamped between the first shell 20 and the second shell 30. Each tooth shape of the wave-shaped tooth structure 211 is arc-shaped, and a smooth transition is formed between adjacent tooth shapes to ensure that the buckle protrusion 41 can smoothly slide through each tooth shape during rotation. The damping buckle member can limit the rotation angle of the microphone by the damping effect, and provide good rotation damping effect and stability, thereby enhancing the stability and comfort of the earphone. The buckle damping member 40 is fixedly connected to the second shell 30, and the buckle protrusion 41 is in clamped engagement with the wave-shaped tooth structure 211. The buckle damping member 40 can rotate relative to the rotating groove 21 to move the buckle protrusion 41 along the arrangement direction of the wave-shaped tooth structure 211. The elastic design of the buckle damping member 40 enables it to generate appropriate damping force during rotation. When the buckle protrusion 41 slides through each tooth shape of the wave-shaped tooth structure 211, the buckle damping member 40 will be elastically deformed slightly, thereby generating a damping effect. This design not only provides stable damping force, but also effectively reduces noise and vibration during rotation.

[0036] The first shell 20 and the second shell 30 can be made of metal or high polymer material. For example, when the second shell 30 is designed as a metal pull rod, it can balance light weight and structural strength, and support multi-angle adjustment. The microphone made of brass has good electrical conductivity and corrosion resistance, which can increase the stability and reliability of the microphone. When the second shell 30 is made of thermoplastic, the thermoplastic is resistant to high temperature and creep, which is used for the internal support structure of the headset skeleton and the microphone, and can ensure that it does not deform during long-term use. The outer layer of part of the microphone is wrapped with silicone or soft rubber, which can improve the holding comfort and reduce friction noise.

[0037] When the user rotates the second shell 30, the second shell 30 rotates relative to the first shell 20. Since the buckle damping member 40 is fixed to the second shell 30, the buckle damping member 40 also rotates. The buckle protrusion 41 moves along the arrangement direction of the wave-shaped tooth structure 211. Due to the wave shape of the wave-shaped tooth structure 211, the buckle protrusion 41 will be subjected to a certain resistance during movement, thereby generating a damping effect. This damping effect can ensure that the microphone remains stable during rotation, avoiding loosening or shaking.

[0038] In some embodiments, the damping piece 40 is provided with two buckling blocks 41, which are in clamping cooperation with the wave-shaped clamping teeth structure 211. The two buckling blocks 41 are located on opposite sides of the damping piece 40. The symmetrical arrangement of the two buckling blocks 41 can ensure that the damping piece 40 is uniformly stressed during rotation, avoiding excessive unilateral stress that may cause wear or failure. The surface of the buckling block 41 is smooth and flat to avoid wear of the structure caused by the uneven surface of the buckling block 41 contacting the wave-shaped clamping teeth structure 211. For example, the contact surface of the wave-shaped clamping teeth structure 211 contacting the buckling block 41 is a curved surface, and the contact surface of the buckling block 41 contacting the wave-shaped clamping teeth structure 211 is a curved surface. This curved surface contact design can reduce the frictional resistance of the contact surface and prolong the service life of the device. In some embodiments, the damping piece 40 can be provided with three buckling blocks 41, which are arranged at intervals, and the adjacent two buckling blocks 41 are arranged at an angle of 120°. This arrangement can ensure that the damping piece 40 is uniformly stressed during rotation, thereby improving the rotation life of the microphone shaft and increasing the reliability of the damping rotation device 10.

[0039] The damping piece 40 is a hollow annular structure 42 with elasticity. The radial length of the buckling block 41 along the damping piece 40 is greater than the width of the hollow annular structure 42. The hollow annular structure 42 is opened inwardly to the damping piece axis. The hollow annular structure 42 can cause a certain elastic deformation of the damping piece 40 during rotation, thereby providing a good damping effect and preventing the damping piece 40 from being easily damaged by fatigue. In addition, to prevent the damping piece 40 from moving during rotation, the bottom of the rotating groove 21 is provided with a limiting block 212. The limiting block 212 abuts against the inner surface of the damping piece 40 to prevent the damping piece 40 from moving radially during rotation. The design of the limiting block 212 can ensure that the damping piece 40 remains stable during rotation, thereby preventing a decrease in damping effect caused by displacement.

[0040] A limiting groove 213 is formed in the rotating groove 21, and the second housing 30 is provided with a sliding block 31 that is slidingly arranged in the limiting groove 213 to limit the rotation angle of the second housing 30 relative to the first housing 20. Specifically, the sliding block 31 can be cylindrical, and the width of the limiting groove 213 is slightly greater than the width of the sliding block 31, so that the sliding block 31 can smoothly slide in the limiting groove 213. In some embodiments, multiple sliding blocks 31 and multiple limiting grooves 213 can be provided, and the multiple sliding blocks 31 are arranged at intervals, and the multiple limiting grooves 213 are arranged at intervals, and the corresponding sliding blocks 31 can slide in the corresponding limiting grooves 213. Through the cooperation of the limiting groove 213 and the sliding block 31, the rotation angle of the second housing 30 relative to the first housing 20 can be accurately controlled, thereby avoiding the inconvenience caused by excessive or insufficient rotation angle.

[0041] In use, the damping rotation device 10, the buckle damping piece 40 needs to be installed between the first shell 20 and the second shell 30, since the first shell 20 and the second shell 30 are rotationally connected, when the two are rotationally connected, the position of the buckle damping piece 40 cannot be displaced, therefore, in some embodiments, a mounting groove 43 can be formed in the peripheral wall of the buckle damping piece 40, the buckle damping piece 40 is clamped and fixed to the second shell 30 through the mounting groove 43, so that the buckle damping piece 40 can rotate synchronously with the second shell 30. In some embodiments, the mounting groove 43 is an arc-shaped groove, which can ensure that the connection between the buckle damping piece 40 and the second shell 30 is firm, and avoid loosening or falling off during rotation. In some embodiments, the peripheral wall of the buckle damping piece 40 forms two mounting grooves 43, which are located on opposite sides of the buckle damping piece 40, which can clamp and fix the buckle damping piece 40 to the second shell 30 in two directions, improving the positional stability of the buckle damping piece 40.
