Description

Technical Field

[0001] The utility model relates to the technical field of earphones, in particular to a damping mechanism and a headphone. Background Art

[0002] At present, the sliding arm mechanisms of the on - market over - ear headphones mainly adopt a "metal shrapnel + plastic groove mechanism" or a "silicone rubber ring + sliding arm mechanism" to realize the up - and - down movement function of the headphone sliding arm. For the former, it mainly uses the compression and rebound of the shrapnel to make the convex platform in the middle move back and forth on the plastic groove, without damping effect. For the latter, it mainly uses the interference fit between the silicone rubber ring and the metal or plastic sliding arm to form a frictional damping force. Operators need to adjust the hardness of the silicone rubber and the interference amount to obtain a satisfactory damping force. Therefore, the requirements for the hardness of the silicone rubber ring and the matching precision between the silicone rubber ring and the sliding arm are relatively high, and the material cost is relatively large.

[0028] The present utility model will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model are shown in the drawings, rather than all structures.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] As Figures 1-5 shown, this embodiment provides a damping mechanism, which includes a support member 1 and a damping assembly 2. The support member 1 is provided with a chute 11 and a first through hole 12 communicating with the chute 11. One end of the damping assembly 2 is slidably disposed in the chute 11. The end of the damping assembly 2 extending into the chute 11 is a sealed end. The sealed end and the end of the chute 11 close to the first through hole 12 form an adjustment chamber 111. The adjustment chamber 111 communicates with the outside through the first through hole 12. When the damping assembly 2 slides in the chute 11, the pressure in the adjustment chamber 111 changes, and damping is generated.

[0033] In this embodiment, the support member 1 is provided with a chute 11 and a first through hole 12 communicating with the chute 11. One end of the damping assembly 2 is slidably disposed in the chute 11. The end of the damping assembly 2 extending into the chute 11 is a sealed end. The sealed end and the end of the chute 11 close to the first through hole 12 form an adjustment chamber 111. The adjustment chamber 111 communicates with the outside through the first through hole 12. By providing the first through hole 12, it can ensure that the gas in the adjustment chamber 111 can smoothly exchange with the outside world, ensuring that the damping assembly 2 can slide smoothly in the chute 11. When the damping assembly 2 slides in the chute 11, by compressing or expanding the gas in the adjustment chamber 111, the pressure in the adjustment chamber 111 changes. When the pressure in the adjustment chamber 111 changes, it generates damping for the movement of the damping assembly 2 relative to the support member 1, without the need for a complex and precise mechanical structure to generate the damping effect, reducing the requirement for the matching precision between the support member 1 and the damping assembly 2 and saving the material cost. Through the above settings, the damping mechanism of this embodiment can generate a good damping feeling and reduce the material cost.

[0034] The specific structure of the damping mechanism will be described below:

[0035] Specifically, as Figure 4 shown, the damping component 2 can divide the sliding groove 11 into an adjustment cavity 111 and a balance cavity 112. The balance cavity 112 communicates with the outside. The user can pull the damping component 2 out of or push it into the sliding groove 11 through the balance cavity 112, which is convenient for the user to operate and improves the operation convenience.

[0036] Specifically, as Figure 3 and Figure 4 shown, the damping mechanism further includes a pressure adjustment component 30. The pressure adjustment component 30 is arranged at the first through hole 12 and can adjust the magnitude of the gas flow velocity between the adjustment cavity 111 and the outside. By adjusting the flow velocity of the gas passing through the first through hole 12, the sliding smoothness and damping feeling of the damping component 2 sliding in the sliding groove 11 can be balanced, ensuring that when the user adjusts the position of the damping component 2, the user can feel sufficient resistance and will not feel laborious due to excessive damping.

[0037] Specifically, as Figure 4 shown, the pressure adjustment component 30 includes a breathable member 3. The breathable member 3 covers the outside of the first through hole 12, enabling the adjustment cavity 111 to smoothly exchange gas with the outside through the first through hole 12 and the breathable member 3. Moreover, by finely designing parameters such as the specific material, pore size, and number of holes of the breathable member 3, precise control of the gas flow velocity can be achieved, which helps to precisely adjust the damping feeling. Among them, the breathable member 3 can be selected from a breathable film or a breathable plate, such as a polyurethane breathable film, a polytetrafluoroethylene breathable film, etc. The specific structure and material of the breathable member 3 are not limited too much here.

[0038] More specifically, as Figure 4As shown, the pressure regulating assembly 30 further includes a fixing member 4. The fixing member 4 is fixed to the support member 1 and presses against the air permeable member 3 to adjust the magnitude of the gas flow rate between the regulating cavity 111 and the outside, making the regulation of the gas flow more precise. It can be understood that when the pressure of the fixing member 4 pressing against the air permeable member 3 is small, the flow rate of the gas through the air permeable member 3 will be greater, and when the pressure between the fixing member 4 and the air permeable member 3 is large, the flow rate of the gas through the air permeable member 3 will be smaller. By the above method, the magnitude of the gas flow rate between the regulating cavity 111 and the outside can be adjusted, thereby driving the change of the air pressure in the regulating cavity 111 to meet the user's requirement for the damping feeling of the damping assembly 2 moving relative to the sliding groove 11. The fixing member 4 is provided with a second through hole 41 communicating with the first through hole 12. One end of the second through hole 41 faces the air permeable member 3, and the other end communicates with the outside, so that the gas in the regulating cavity 111 can smoothly exchange with the outside through the first through hole 12, the air permeable member 3 and the second through hole 41.

[0039] In this embodiment, the second through hole 41 is aligned with the first through hole 12 to ensure that the gas flowing through the first through hole 12 can smoothly exchange with the outside through the second through hole 41. In other embodiments, the second through hole 41 and the first through hole 12 may be arranged in a staggered manner, as long as there is a communicating channel between the two to achieve the above functions.

[0040] More specifically, in this embodiment, the fixing member 4 is a plastic tail plug, which is not only light in texture, but also convenient for obtaining materials for processing and has a low cost. In other embodiments, the fixing member 4 is a rubber tail plug. Here, the specific structure and material of the fixing member 4 are not overly limited, as long as the above functions can be achieved.

[0041] Specifically, as Figure 4 shown, the support member 1 is provided with a connection groove 13. The fixing member 4 is threadedly connected to the connection groove 13 to adjust the magnitude of the pressing force of the fixing member 4 against the air permeable member 3. This connection method not only has high stability and reliability, but also is convenient for the installation and disassembly of the fixing member 4, helps to reduce the maintenance cost and improve the work efficiency. In addition, when the tightening force between the fixing member 4 and the connection groove 13 is small, the pressure of the fixing member 4 pressing against the air permeable member 3 is small, and the flow rate of the gas through the air permeable member 3 will be greater, so the damping feeling of the damping assembly 2 moving relative to the sliding groove 11 is small; when the tightening force between the fixing member 4 and the connection groove 13 is large, the pressure of the fixing member 4 pressing against the air permeable member 3 is large, and the flow rate of the gas through the air permeable member 3 will be smaller, so the damping feeling of the damping assembly 2 moving relative to the sliding groove 11 is large.

[0042] More specifically, one end of the first through hole 12 communicates with the adjustment cavity 111, and the other end communicates with the connection groove 13. The air-permeable member 3 is disposed at one end of the connection groove 13 close to the adjustment cavity 111. When the fixing member 4 is threadedly connected to the connection groove 13, it can abut against the air-permeable member 3 and tightly press the air-permeable member 3 against the other end of the first through hole 12, so that the outside air can smoothly exchange with the air in the adjustment cavity 111 through the second through hole 41, the air-permeable member 3 and the first through hole 12, and the air flow rate is adjusted by the pressing action of the fixing member 4 on the air-permeable member 3 to meet the damping requirements of the damping assembly 2 during sliding.

[0043] Specifically, as Figures 3-5 shown, the damping assembly 2 includes a damper 21 and a sliding member 22. The damper 21 is a sealed end and is slidably disposed in the chute 11. The damper 21 is sleeved on the sliding member 22 and elastically abuts against the inner wall of the chute 11. The user can pull or push the sliding member 22 in the chute 11, thereby driving the damper 21 to slide relative to the inner wall of the chute 11, and generating a damping feeling through the frictional action between the damper 21 and the inner wall of the chute 11.

[0044] More specifically, in this embodiment, the damper 21 is a silicone rubber head, which is the sealed end of the damping assembly 2, and the sliding member 22 is a stainless steel rod. The silicone rubber head is sleeved on one end of the stainless steel rod and is slidably disposed in the chute 11. The silicone rubber head can generate sufficient damping force when contacting the inner wall of the chute 11, thereby slowing down the movement speed of the stainless steel rod and generating a better damping feeling. In other embodiments, the damper 21 is a plastic sleeve, the sliding member 22 is a plastic rod, the plastic sleeve is sleeved on the end of the plastic rod, and is slidably connected to the chute 11, and a damping feeling is generated through the frictional action between the plastic and the inner wall of the chute 11. It can be understood that the specific structures and materials of the damper 21 and the sliding member 22 are not limited, as long as the above functions can be achieved.

[0045] Specifically, the sliding member 22 is spaced from the inner wall of the chute 11 and can form a balance cavity 112. Since the user generally holds the sliding member 22 to pull or push, dirt is likely to be generated on the surface of the sliding member 22. By spacing the sliding member 22 from the inner wall of the chute 11, the sliding member 22 does not contact the inner wall of the chute 11, improving the user experience and preventing dirt from affecting the sliding damping of the damping assembly 2 relative to the support member 1. At the same time, the damper 21 elastically abuts against the inner wall of the chute 11, and can push out the dirt in the balance cavity 112 formed by the spacing between the sliding member 22 and the inner wall of the chute 11.

[0046] Specifically, as Figure 4As shown, the outer wall surface of the damping member 21 elastically abuts against the inner wall of the chute 11 and is unevenly arranged, so as to increase the frictional resistance between the damping member 21 and the inner wall of the chute 11, improve the damping feel and is not easy to fall off. Among the sliding member 22 and the damping member 21, one is provided with a convex block 221, and the other is provided with a clamping groove 211 that is engaged with the convex block 221. Such a setting can enhance the connection strength between the damping member 21 and the sliding member 22 and prevent relative sliding or detachment during movement. Of course, in other embodiments, a dovetail groove structure can also be provided between the sliding member 22 and the damping member 21 to strengthen the fixation between the two.

[0047] More specifically, in this embodiment, the convex block 221 is provided on the sliding member 22, and the clamping groove 211 is opened on the damping member 21. Through the engagement between the convex block 221 and the clamping groove 211, the damping member 21 can be stably installed on the sliding member 22. In other embodiments, the convex block 221 is provided on the damping member 21, and the clamping groove 211 is opened on the sliding member 22. That is, as long as the above functions can be realized, the specific positions of the convex block 221 and the clamping groove 211 are not overly limited here.

[0048] Specifically, as Figure 3 and Figure 5 shown, the damping mechanism further includes a limiting member 5. The limiting member 5 protrudes inward from the inner wall of the chute 11 so that when the damping assembly 2 slides in the chute 11, it is blocked by the limiting member 5, which can play a role in limiting the sliding process of the damping assembly 2 and prevent the damping assembly 2 from being completely withdrawn from the chute 11. It can be understood that the inner wall surface of the limiting member 5 protrudes from the inner wall of the chute 11. Since the damping member 21 is sleeved on the sliding member 22 and the dimension protruding in the radial direction of the sliding member 22 slides and abuts against the inner wall of the chute 11, and there is a gap between the sliding member 22 and the inner wall of the chute 11 to form a balance cavity 112. When the damping assembly 2 slides to the limiting member 5, because the radial dimension of the damping member 21 is larger than that of the sliding member 22 and abuts against the inner wall of the chute 11, and the limiting member 5 protrudes from the inner wall of the chute 11 and protrudes inward, the damping member 21 is blocked by the limiting member 5 to prevent the damping member 21 from falling off the chute 11 due to excessive force.

[0049] More specifically, in this embodiment, the limiting member 5 is a limiting ring and is made of plastic. The limiting ring plays a role in limiting the sliding of the damping member 21 to prevent the damping assembly 2 from detaching from the chute 11. Moreover, by using a limiting ring made of plastic, the material cost can be saved and the overall structure can be made lighter. In other embodiments, the limiting member 5 is a block structure and is made of hard silicone. It is not only light in weight but also can play a role in limiting the damping assembly 2. It can be understood that the specific structure and material of the limiting member 5 are not limited as long as the above functions can be realized.

[0050] The specific working process of the damping mechanism is described below:

[0051] like Figures 1-5 As shown, when the damping assembly 2 slides in the chute 11, the pressure in the regulating chamber 111 changes by compressing or expanding the gas in the regulating chamber 111. When the pressure in the regulating chamber 111 changes, damping is generated to the movement of the damping assembly 2 relative to the support member 1. It is understandable that when the user pulls the slider 22, the slider 22 drives the damping member 21 to slide in the chute 11, so that the regulating chamber 111 draws air from the outside through the breathable member 3, thereby forming a negative pressure damping force. When the user pushes the slider 22 back into the chute 11, the sealing end compresses the air in the regulating chamber 111, thereby forming a positive pressure damping force. When the user wants to adjust the magnitude of the damping force, by screwing the fixing member 4 and adjusting the pressure of the fixing member 4 against the breathable member 3, the flow rate of the gas through the breathable member 3 can be adjusted, thereby affecting the magnitude of the damping force of the damping assembly 2 when it slides relative to the support member 1.

[0052] like Figures 1-5 As shown, this embodiment also provides a headphone, which includes an earphone body 100 and a damping mechanism. The damping mechanism is provided on the earphone body 100 and can produce a good damping feeling. Moreover, the damping feeling is mainly achieved by the compression and expansion of the gas in the adjustment cavity 111 by the sealing end. The damping effect does not require a complex and precise mechanical structure to produce the damping effect, and the matching precision requirements between the support member 1 and the damping assembly 2 are reduced, thereby reducing material costs.

[0053] Specifically, the earphone body 100 extends in an arc shape, and each earphone body 100 is provided with two damping mechanisms, one at each end of the earphone body 100. The pressure regulating assembly 30 can adjust the velocity of gas flow between the regulating chamber 111 and the outside world, thereby balancing the smoothness and damping feel of the damping assembly 2 as it slides in the chute 11. This, in turn, improves the poor consistency of the damping assembly 2 at the left and right ends of the earphone body 100 during sliding. Furthermore, the spacing of the slider 22 from the inner wall of the chute 11 helps improve the damping effect and prevents dirt on the slider 22 from directly contacting the inner wall of the chute 11 and affecting the damping feel.

[0054] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
