Therefore, the hardness of the silicone rubber ring and the matching accuracy of the silicone rubber ring and the sliding arm are required to be high, and the material cost is relatively high. Moreover, when the silicone rubber ring slides with the metal or plastic sliding arm, it is easy to produce a sense of stuttering, and the damping effect is poor, which brings a bad user experience.

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

[0033] like Figure 1-Figure 5 As 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 slide groove 11 and a first through hole 12 connected to the slide groove 11, and the damping assembly 2 can separate the slide groove 11 into an adjustment chamber 111 and a balance chamber 112, and the balance chamber 112 is connected to the outside. One end of the damping assembly 2 is slidably arranged in the slide groove 11, and the end of the damping assembly 2 extending into the slide groove 11 is a sealing end, and the sealing end and the end of the slide groove 11 close to the first through hole 12 form an adjustment chamber 111, and the adjustment chamber 111 is connected to the outside through the first through hole 12. When the damping assembly 2 slides in the slide groove 11, the pressure in the adjustment chamber 111 changes, and damping is generated.

[0034] In this embodiment, the support member 1 is provided with a slide groove 11 and a first through hole 12 connected to the slide groove 11. The damping component 2 can separate the slide groove 11 into an adjustment chamber 111 and a balance chamber 112. The balance chamber 112 is connected to the outside. The user can smoothly pull the damping component 2 from the slide groove 11 through the balance chamber 112, or push the damping component 2 into the slide groove 11, which reduces the sense of jamming and improves the user's experience. One end of the damping component 2 is slidably arranged in the slide groove 11, and the end of the damping component 2 extending into the slide groove 11 is a sealed end. The sealed end and the end of the slide groove 11 close to the first through hole 12 form an adjustment chamber 111. The adjustment chamber 111 is connected to the outside through the first through hole 12, which can ensure that the gas in the adjustment chamber 111 can be smoothly exchanged with the outside world, and ensure that the damping component 2 can achieve smooth sliding in the slide groove 11. When the damping component 2 slides in the slide groove 11, the gas in the regulating chamber 111 is compressed or expanded, so that the pressure in the regulating chamber 111 changes. When the pressure in the regulating chamber 111 changes, damping is generated for the movement of the damping component 2 relative to the support 1. No complex and precise mechanical structure is required to produce the damping effect, which reduces the matching accuracy requirements between the support 1 and the damping component 2 and saves material costs. Through the above settings, the damping effect of the damping mechanism of this embodiment is better and the material cost is lower.

[0035] The specific structure of the damping mechanism is described below:

[0036] Specifically, Figure 3 and Figure 4 As shown, the damping mechanism also includes a pressure regulating component 30, which is arranged at the first through hole 12 and can adjust the gas flow rate between the regulating chamber 111 and the outside world. By adjusting the flow rate of the gas through the first through hole 12, the sliding smoothness and damping feeling of the damping component 2 when sliding in the slide groove 11 can be balanced, ensuring that the user can feel sufficient resistance when adjusting the position of the damping component 2 without feeling strenuous due to excessive damping.

[0037] Specifically, Figure 4 As shown, the pressure regulating assembly 30 includes a breathable member 3, which is sealed on the outside of the first through hole 12, so that the regulating chamber 111 can smoothly exchange gas with the outside through the first through hole 12 and the breathable member 3, and by finely designing the specific material, pore size, number of holes and other parameters of the breathable member 3, it is possible to achieve accurate control of the gas circulation speed, thereby facilitating accurate adjustment of the damping feeling. Among them, the breathable member 3 can be a breathable film or a breathable plate, such as a polyurethane breathable film, a polytetrafluoroethylene breathable film, etc., and the specific structure and material of the breathable member 3 are not limited too much here.

[0038] More specifically, if Figure 4As shown, the pressure regulating assembly 30 also includes a fixing member 4, which is fixed to the support member 1 and presses against the air-permeable member 3 to adjust the gas flow velocity between the regulating chamber 111 and the outside world, so that the gas flow regulation is more accurate. It can be understood that when the pressure of the fixing member 4 pressing on the air-permeable member 3 is small, the gas flow velocity 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 gas flow velocity through the air-permeable member 3 will be smaller. In the above manner, the gas flow velocity between the regulating chamber 111 and the outside world can be adjusted, thereby driving the air pressure in the regulating chamber 111 to change, and satisfying the user's damping feeling requirements for the movement of the damping assembly 2 relative to the slide 11. A second through hole 41 connected to the first through hole 12 is provided on the fixing member 4, one end of the second through hole 41 is arranged toward the air-permeable member 3, and the other end is connected to the outside, so that the gas in the regulating chamber 111 can be smoothly exchanged with the outside world 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 be smoothly exchanged with the outside through the second through hole 41. In other embodiments, the second through hole 41 and the first through hole 12 can be staggered, as long as there is a connecting passage between the two to achieve the above-mentioned functional role.

[0040] More specifically, in this embodiment, the fixing member 4 is a plastic tail plug, which is not only light in texture, but also easy to obtain and process, and has a low cost. In other embodiments, the fixing member 4 is a rubber tail plug, and the specific structure and material of the fixing member 4 are not limited too much, as long as the above-mentioned functions can be achieved.

[0041] Specifically, Figure 4 As shown, the support member 1 is provided with a connection groove 13, and the fixing member 4 is threadedly connected to the connection groove 13 to adjust the pressure of the fixing member 4 on the air-permeable member 3. This connection method not only has high stability and reliability, but also facilitates the installation and removal of the fixing member 4, which helps to reduce maintenance costs and improve 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 on the air-permeable member 3 is small, and the flow speed of the gas through the air-permeable member 3 will be greater, so the damping feeling of the damping component 2 relative to the movement of the slide 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 on the air-permeable member 3 is large, and the flow speed of the gas through the air-permeable member 3 is small, so the damping feeling of the damping component 2 relative to the movement of the slide groove 11 is large.

[0042] More specifically, one end of the first through hole 12 is connected to the regulating chamber 111, and the other end is connected to the connecting groove 13. The air permeable member 3 is arranged at one end of the connecting groove 13 close to the regulating chamber 111. When the fixing member 4 is threadedly connected to the connecting groove 13, it can abut against the air permeable member 3 and press the air permeable member 3 tightly against the other end of the first through hole 12, so that the external gas can be smoothly exchanged with the gas in the regulating chamber 111 through the second through hole 41, the air permeable member 3 and the first through hole 12, and the air circulation speed is adjusted by the pressing effect of the fixing member 4 on the air permeable member 3 to meet the damping requirements of the damping component 2 when sliding.

[0043] Specifically, Figure 1-Figure 5 As shown, the damping assembly 2 includes a damping member 21 and a sliding member 22. The damping member 21 is a sealed end and is slidably disposed in the slide groove 11. The damping member 21 is sleeved on the sliding member 22 and elastically abuts against the inner wall of the slide groove 11. The user can pull the sliding member 22 from the slide groove 11, or push the sliding member 22 into the slide groove 11, thereby driving the damping member 21 to slide relative to the inner wall of the slide groove 11, and generating a damping feeling through the friction between the damping member 21 and the inner wall of the slide groove 11.

[0044] More specifically, in the present embodiment, the damping member 21 is a silicone rubber head, which is the sealing 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 slide groove 11. The silicone rubber head can generate sufficient damping force when in contact with the inner wall of the slide groove 11, thereby slowing down the movement speed of the stainless steel rod and generating a better damping feeling. In other embodiments, the damping member 21 is a plastic sleeve, and the sliding member 22 is a plastic rod. The plastic sleeve is sleeved on the end of the plastic rod and is slidably connected in the slide groove 11, and the friction between the plastic and the inner wall of the slide groove 11 generates a damping feeling. It can be understood that there is no limitation on the specific structure and material of the damping member 21 and the sliding member 22, as long as the above-mentioned functional effects can be achieved.

[0045] Specifically, Figure 4 As shown, the sliding member 22 is spaced apart from the inner wall of the slide groove 11 to form a balancing cavity 112. Since the user generally holds the sliding member 22 to pull or push, dirt is easily generated on the surface of the sliding member 22. However, the sliding member 22 is spaced apart from the inner wall of the slide groove 11, so that the sliding member 22 does not contact the inner wall of the slide groove 11, which improves the user experience and prevents dirt from affecting the sliding damping of the damping component 2 relative to the support member 1. At the same time, the damping member 21 elastically abuts against the inner wall of the slide groove 11, and can push out the dirt in the balancing cavity 112 spaced apart from the inner wall of the slide groove 11.

[0046] Specifically, Figure 4 and Figure 5As shown, the outer wall surface of the damping member 21 elastically abuts against the inner wall of the slide 11 and is uneven, so as to increase the friction resistance between the damping member 21 and the inner wall of the slide 11, improve the damping feel and prevent it from falling off. One of the sliding member 22 and the damping member 21 is provided with a protrusion 221, and the other is provided with a slot 211 that is engaged with the protrusion 221. Such a setting can enhance the connection strength between the damping member 21 and the sliding member 22, and prevent relative sliding or separation during movement. Of course, in other embodiments, a dovetail groove structure can 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 protrusion 221 is provided on the sliding member 22, and the slot 211 is provided on the damping member 21. The damping member 21 can be stably mounted on the sliding member 22 through the engagement between the protrusion 221 and the slot 211. In other embodiments, the protrusion 221 is provided on the damping member 21, and the slot 211 is provided on the sliding member 22. That is, as long as the above-mentioned functions can be achieved, the specific positions of the protrusion 221 and the slot 211 are not limited too much.

[0048] Specifically, Figure 1-Figure 5 As shown, the damping mechanism also includes a limit member 5, which protrudes inward from the inner wall of the slide groove 11 so that when the damping component 2 slides in the slide groove 11, it is stopped by the limit member 5, thereby limiting the sliding process of the damping component 2 and preventing the damping component 2 from being completely pulled out of the slide groove 11. It can be understood that the inner wall surface of the limit member 5 protrudes from the inner wall of the slide groove 11. Since the damping member 21 is sleeved on the sliding member 22 and protrudes from the radial direction of the sliding member 22 and slides against the inner wall of the slide groove 11, and there is a gap between the sliding member 22 and the inner wall of the slide groove 11 to form a balance chamber 112, when the damping assembly 2 slides to the limit member 5, since the radial dimension of the damping member 21 is greater than that of the sliding member 22 and is against the inner wall of the slide groove 11, and the limit member 5 protrudes inward from the inner wall of the slide groove 11, the damping member 21 is stopped by the limit member 5 to prevent the damping member 21 from falling off the slide groove 11 due to excessive force.

[0049] More specifically, in this embodiment, the limiter 5 is a limit ring and is made of plastic. The limit ring has a limiting effect on the sliding of the damping member 21 to prevent the damping assembly 2 from escaping from the slide groove 11. Moreover, by using a limit ring made of plastic, material costs can be saved and the overall structure can be made lighter. In other embodiments, the limiter 5 is a block structure and is made of hard silicone. It is not only lightweight, but also can limit the damping assembly 2. It can be understood that there is no limitation on the specific structure and material of the limiter 5, as long as the above-mentioned functions can be achieved.

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

[0051] like Figure 1-Figure 5 As shown, when the damping assembly 2 slides in the slide groove 11, the gas in the regulating chamber 111 is compressed or expanded, so that the pressure in the regulating chamber 111 changes. When the pressure in the regulating chamber 111 changes, damping is generated for the movement of the damping assembly 2 relative to the support member 1. It can be understood that when the user pulls the sliding member 22, the sliding member 22 drives the damping member 21 to slide in the slide groove 11, so that the regulating chamber 111 draws air from the outside through the air-permeable member 3 to form a negative pressure damping force, and when the user pushes the sliding member 22 back into the slide groove 11, the sealing end compresses the air in the regulating chamber 111 to form 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 air-permeable member 3, the circulation speed of the gas through the air-permeable 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 Figure 1-Figure 5 As shown, this embodiment also provides a headset, which includes an earphone body 100 and a damping mechanism, wherein the damping mechanism is disposed 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, and no complex and precise mechanical structure is required to produce the damping effect, which reduces the matching accuracy requirements between the support member 1 and the damping component 2, thereby reducing the material cost.

[0053] Specifically, Figure 3 and Figure 4 As shown, the earphone body 100 extends in an arc shape, and one earphone body 100 is provided with two damping mechanisms, which are respectively arranged at the two ends of the earphone body 100. The pressure regulating component 30 can adjust the gas flow velocity between the regulating chamber 111 and the outside world, thereby balancing the sliding smoothness and damping feeling of the damping component 2 when sliding in the slide groove 11, thereby optimizing the problem of poor consistency of the damping components 2 at the left and right ends of the earphone body 100 when sliding. Moreover, the interval arrangement of the sliding member 22 and the inner wall of the slide groove 11 helps to improve the damping effect and prevent the dirt on the sliding member 22 from directly contacting the inner wall of the slide groove 11 and affecting the damping feeling.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
