[0048] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0049] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0050] like Figures 1 to 10 As shown, this embodiment provides a damping mechanism, which includes a housing 100, a sliding base 200, a slider 300, and a damping member 400. The sliding base 200 is disposed within the housing 100 and has a first, elongated damping portion 211. The slider 300 is movably constrained to the housing 100. The damping member 400 is fixed to the slider 300 and can move synchronously with the slider 300. The damping member 400 has a second damping portion 421 that can abut against the first damping portion 211. During the reciprocating movement of the slider 300 relative to the housing 100, sliding friction is generated between the second damping portion 421 and the first damping portion 211. The sliding base 200 and the damping member 400 are both made of polyoxymethylene.

[0051] The damping mechanism, by providing a sliding base 200 and a damping element 400, generates friction between them during the squeezing and relative sliding process. Due to the high hardness of polyoxymethylene, it is not easily deformed, thus ensuring a stable damping feel. Without requiring a large deformation space, this helps reduce the space occupied within the housing 100, thereby reducing the volume of the housing 100, further facilitating the miniaturization of the damping mechanism and the earphones, and reducing costs. Furthermore, the self-lubricating properties of polyoxymethylene reduce the possibility of noise during the friction process.

[0052] Combine Figure 3 、 4 As shown in Figures 6 and 7, the damping mechanism further includes a fixing member 230. The sliding base 200 is provided with a sliding groove 212. The sliding member 300 is slidably disposed in the sliding groove 212. The damping member 400 is located outside the sliding groove 212, and the sliding member 300 and the damping member 400 are connected by the fixing member 230. The first damping portion 211 is located outside the sliding groove 212, and the second damping portion 421 is located outside the sliding groove 212 and is arranged opposite to the first damping portion 211. To increase the strength of the entire damping mechanism, the outer diameter of the cross-sectional profile of the sliding base 200 is appropriately increased. However, to reduce the size of the damping mechanism, the sliding groove 212 is provided on the sliding base 200, and the sliding member 300 is slidably disposed in the sliding groove 212. This allows the sliding member 300 to partially overlap the sliding base 200 in a direction perpendicular to the extension direction of the damping mechanism, thereby reducing the cross-sectional area of ​​the damping mechanism and thus reducing its volume.

[0053] In some embodiments, the sliding base 200 is provided with a planar first damping portion 211 on each side of the opening of the sliding groove 212, and the bottom surface of the damping member 400 forms two planar second damping portions 421, which are separated on both sides of the sliding groove 212. The second damping portion 421 is pressed inwardly against the first damping portion 211, and the limiting surface 237 of the fixing member 230 located in the sliding groove 212 abuts outward against the inner side wall of the sliding groove 212.

[0054] The corresponding contact between the two first damping parts 211 and the two second damping parts 421 makes the structure between the sliding member 300 and the sliding base 200 more stable, the friction force more balanced, and easy to control; at the same time, the contact area is increased, so that the wear rate is further reduced, and the magnitude of the friction force between the two is also easier to remain unchanged, that is, the damping feel is easier to remain unchanged, thereby improving the user experience.

[0055] Here, the inside and outside are relative to the center line of the sliding slot 212 , that is, the direction close to the center line of the sliding slot 212 is inward, and the direction away from the center line of the sliding slot 212 is outward.

[0056] The sliding base 200 has a sliding protrusion 214 on both sides of the opening of the sliding groove 212 . The damping member 400 has two sliding grooves 422 . Each sliding protrusion 214 is slidably disposed in the corresponding sliding groove 422 . Exemplarily, the two opposite side walls at the opening of the sliding groove 212 are relatively protruded to form a closing portion 213, and the top surface of the closing portion 213 forms a first damping portion 211. The damping member 400 includes a mounting portion 410 and a friction portion 420 connected to each other. The mounting portion 410 is connected to the fixing member 230 and partially extends out of the sliding groove 212. The friction portion 420 is located on the outside of the sliding groove 212, and the extension direction is perpendicular to the extension direction of the sliding groove 212. The length of the friction portion 420 is greater than the width of the sliding groove 212. The bottom surface of the friction portion 420 forms two second damping portions 421, and the second damping portion 421 is pressed downwardly on the first damping portion 211. The limiting surface 237 of the fixing member 230 located in the sliding groove 212 presses upward against the bottom surface of the receiving opening 213. Each of the closing portions 213 has a sliding protrusion 214 on its upper side. The friction portion 420 of the damping element 400 has two sliding grooves 422, and each sliding protrusion 214 slides in a corresponding sliding groove 422. The fixing member 230 is made of metal, and the friction between the fixing member 230 and the closing portion 213 is negligible. Of course, solid lubricant can also be applied between the fixing member 230 and the closing portion 213.

[0057] The setting of the sliding groove 422 enables the friction portion 420 of the damping member 400 to form a cantilever structure, that is, the friction portion 420 includes a damping transverse portion 423 and a damping vertical portion 424 connected to each other, wherein the damping transverse portion 423 serves as a cantilever structure and can provide a certain elasticity for the damping vertical portion 424, and the bottom end of the damping vertical portion 424 forms the first damping portion 211; so that the first damping portion 211 has a larger elastic change space, while ensuring the damping effect, the service life is improved.

[0058] The sliding protrusion 214 is arranged at the top of the closing portion 213. This arrangement can increase the structural strength of the closing portion 213, improve its ability to resist deformation, and help ensure the stability of the damping feel.

[0059] Combine Figure 7As shown, the fixing member 230 is provided with a fixing channel 231, and the sliding member 300 is disposed in the fixing channel 231 and is connected to the fixing member 230 by at least one of screw connection, bonding, or interference fit. Specifically, the sliding member 300 is a hollow structure, and the side wall of the sliding member 300 is provided with a bonding hole 320 extending through the interior of the sliding member 300. The bonding hole 320 extends perpendicular to the extension direction of the sliding member 300. During use, glue is dispensed through the bonding hole 320, allowing the glue to flow into the gap between the sliding member 300 and the fixing member 230, thereby improving assembly efficiency. Applying glue after adjusting the position can prevent the glue from drying quickly and causing misalignment between the two during installation.

[0060] Combine Figure 4 As shown, in order to prevent the sliding member 300 and the fixing member 230 from rotating relative to each other, a first anti-rotation plane 310 is provided at the socket joint of the sliding member 300 and the fixing member 230, and a second anti-rotation plane 234 is provided on the contour of the fixing channel 231, and the first anti-rotation plane 310 and the second anti-rotation plane 234 are parallel to each other.

[0061] The sliding member 300 has a circular cross-section and slides within the sliding groove 212. A sliding protrusion 233 is provided at the lower end of the fixing member 230. The sliding base 200 has a sliding track 218 recessed into the inner wall of the sliding groove 212. The sliding protrusion 233 slides within the sliding track 218 along the sliding direction of the sliding member 300. As the sliding member 300 slides relative to the housing 100, it drives the fixing member 230 to slide, causing the sliding protrusion 233 to slide within the sliding track 218, preventing deviation. This limits the sliding trajectory of the sliding member 300 and prevents positional shifting between the damping member 400 and the sliding base 200 caused by a deflected sliding member 300, thereby ensuring the damping effect. The sliding protrusion 233 is provided with a receiving groove 2331. The provision of the receiving groove 2331 facilitates injection molding of the sliding protrusion 233 and reduces the possibility of collapse. Among them, the bottom of the accommodating groove 2331 is provided with a threaded hole that penetrates into the fixing channel 231. The extension direction of the threaded hole is perpendicular to the extension direction of the fixing channel 231. The locking screw is screwed into the threaded hole and at least partially inserted into the stop hole of the sliding member 300.

[0062] Combine Figure 7 As shown, in order to improve the assembly efficiency of the fixing member 230 and the damping member 400, in some embodiments, the fixing member 230 is protruded with a fixing rod 235, the damping member 400 is provided with a mounting hole, the fixing rod 235 is passed through the mounting hole, and the end of the fixing rod 235 is provided with a clamping groove 236, and a clamping spring 240 is clamped in the clamping groove 236 to press the damping member 400.

[0063] To prevent the damping member 400 from rotating about the axis of the fixing rod 235, in some embodiments, one of the fixing member 230 and the damping member 400 is provided with a positioning groove 238, and the other is provided with a positioning protrusion. The positioning protrusion and the fixing rod 235 are spaced apart along the sliding direction of the sliding member 300. When the fixing rod 235 is inserted into the mounting hole, the positioning protrusion is inserted into the positioning groove 238. The positioning groove 238 is provided in the fixing member 230, and the damping member 400 is provided with a positioning protrusion. The positioning groove 238 is located on one side of the fixing rod 235. The upper end of the fixing member 230 is provided with a fixing boss 232, and the fixing rod 235 is provided on the top surface of the fixing boss 232. The positioning groove 238 is formed by a recessed portion of the top surface of the fixing boss 232.

[0064] Combine Figure 1 and Figure 2 As shown, since the sliding member 300 is an elongated structure, when in use, the housing 100 needs to be fixed, and the sliding member 300 is manually grasped and pulled outward or pushed inward to move the sliding member 300 relative to the housing 100. Due to manual operation, it is inevitable that the force is uneven. To prevent this force from affecting the abutment between the damping member 400 and the sliding base 200, thereby affecting the damping feel between the two, in some embodiments, the damping mechanism further includes a guide assembly 500, which has a guide slide 511. The guide assembly 500 is disposed in the housing 100, and the sliding member 300 is disposed in the guide slide 511 and can slide relative to the sliding base 200 under the guidance of the guide slide 511. The provision of the guide assembly 500 ensures that, except for the push-pull force, all other forces of the manual push-pull force are constrained and do not act between the damping member 400 and the sliding base 200, thereby not affecting the friction between the two, thereby ensuring the damping feel.

[0065] The guide assembly 500 includes a cylindrical guide member 510 and a connector 520. A guide slideway 511 is disposed within the guide member 510, and the connector 520 connects the guide member 510 to the housing 100. This arrangement facilitates assembly and improves efficiency. Furthermore, when using different models of sliders 300, only the guide member 510 needs to be replaced; the connector 520 can be used universally, reducing mold costs.

[0066] The housing 100 has a mounting channel, and the guide member 510 is partially disposed within the mounting channel. A first engaging groove 512 is disposed on the outer wall of the guide member 510 outside the mounting channel. The housing 100 has a second engaging groove 110. When the guide member 510 is installed in the mounting channel, the first engaging groove 512 and the second engaging groove 110 form a connecting channel. The connecting channel extends perpendicularly to the extending direction of the mounting channel, and the connector 520 can be inserted into the connecting channel. This arrangement not only constrains the guide member 510 axially, but also prevents the guide member 510 from rotating about its own axis.

[0067] Two engaging channels are provided, one on each side of the axis of the guide member 510. The connector 520 comprises two parallel, columnar engaging portions 521 and a connecting portion 522 connecting the two engaging portions 521. The two engaging portions 521 can be inserted into the two engaging channels accordingly. The connector 520 is generally U-shaped. During installation, simply hold the connecting portion 522 to insert the two engaging portions 521 into the two engaging channels.

[0068] In order to facilitate the application of the damping mechanism in various devices, the sliding base 200 and the housing 100 are detachably connected. When replacing a device, it is only necessary to adjust the shape of the housing 100.

[0069] Combine Figure 8 and Figure 9 As shown, one side of the sliding base 200 is provided with an insertion protrusion 2191, and the housing 100 is provided with an insertion slot 120, into which the insertion protrusion 2191 is inserted. On the other side of the sliding base 200, a fixing hole 2192 is provided, and the housing 100 is provided with a fixing post 130, which is provided with a fixing screw hole 131. The fastener 132 passes through the fixing hole 2192 and can be screwed into the fixing screw hole 131. There are two insertion protrusions 2191, spaced apart in the left-right direction. There are two insertion slots 120, one corresponding to each of the two insertion protrusions 2191. There are three fixing holes 2192, spaced apart in the left-right direction. There are three fixing posts 130, one corresponding to each of the three fixing holes 2192. Along the left-right direction, two insertion slots 120 are located in the gap between any two fixing holes 2192.

[0070] Combine Figure 5 、 Figure 8 and Figure 10 As shown, the sliding base 200 is provided with a first limiting portion 215 and a second limiting portion 221 at intervals. During the sliding process of the sliding member 300 along the housing 100 , it is stopped when the damping member 400 abuts against the first limiting portion 215 or the sliding member 300 abuts against the second limiting portion 221 .

[0071] The housing 100 is made of plastic. The sliding base 200 and the damping member 400 are both made of polyformaldehyde. Polyformaldehyde can provide a stable buffering effect due to its high strength, high rigidity, high wear resistance, and flexible movement performance.

[0072] In some embodiments, the sliding base 200 includes a sliding body 210 and a stopper 220. The sliding body 210 is provided with a sliding groove 212. One end of the sliding groove 212 extends through the sliding body 210 to facilitate mold opening. The stopper 220 is provided at one end of the sliding groove 212 to seal the end opening of the sliding groove 212 and enhance the strength of the sliding body 210. A stopper ring is provided at the other end of the sliding groove 212. The stopper ring forms a first damping portion 211. The outer diameter of the fixing member 230 is larger than the inner diameter of the stopper ring and can abut against the stopper ring. The stopper 220 is connected to the sliding body 210, and a second limiting portion 221 is provided on the stopper 220. When the sliding member 300 retracts into the sliding groove 212, the fixing member 230 abuts against the stopper ring to achieve position limiting. The sliding body 210 is made of polyoxymethylene.

[0073] The sliding body 210 is provided with a sliding groove 212, in which the sliding member 300 is disposed. The stopper 220 is a cylindrical structure and is sleeved on one end of the sliding body 210. An integrally formed stopper plate is provided at the end of the stopper 220. At least a portion of the stopper plate is located in the sliding groove 212, forming a second limiting portion 221. The damping member 400 is provided with a buffer portion on the side facing the second limiting portion 221 for abutting against the second limiting portion 221. The stopper 220 may be made of metal. The provision of the buffer portion allows the slider 300 to abut against the stopper 220 when it is removed from the sliding groove 212, thereby preventing impact on the damping cross portion 423 and thus ensuring a damping feel.

[0074] The damping member 400 has a strip-shaped buffer block 430 protruding outward from one side of the damping member 400 toward the second limiting portion 221 to form a buffer portion. The buffer block 430 extends in a vertical direction. There are at least two buffer blocks 430, and the two buffer blocks 430 are spaced apart in a direction perpendicular to the direction in which they extend, that is, the two buffer blocks 430 are spaced apart in the front-to-back direction.

[0075] The side wall of the stop member 220 is formed by punching to have a strip-shaped stop portion 222 extending toward the interior of the stop member 220. The outer side wall of the sliding body 210 is provided with a stop groove 216 and a stop protrusion 217. The stop groove 216 and the stop protrusion 217 are arranged at intervals along the extension direction of the sliding groove 212. The stop portion 222 can be inserted into the stop groove 216 and abut the side wall of the stop groove 216 away from the stop protrusion 217. The stop member 220 abuts against the stop protrusion 217. During installation, the stopper 220 is placed over the sliding body 210 and then pushed so that the stopper portion 222 and the sliding body 210 abut against each other and turn outward. When the stopper portion 222 moves to the stopper groove 216, the end of the stopper portion 222 enters the stopper groove 216 under its own elastic force, and the end of the stopper 220 abuts the stopper protrusion 217, thereby completing the axial limit of the stopper 220 and the sliding body 210. Furthermore, there are at least two stopper grooves 216 and at least two stopper portions 222, each of which is arranged in a one-to-one correspondence. The stopper portions 222 are spaced apart around the circumference of the stopper 220 to achieve circumferential limit of the stopper 220. At the same time, contact between the stopper plate and the sidewalls of the opening of the sliding groove 212 is prevented, thereby affecting the limit accuracy.

[0076] This embodiment also provides a headset, comprising any of the above damping mechanisms.
