Description

[Technical Field]

[0001] This invention relates to the field of headphone technology, and more particularly to a damping mechanism and a headset. [Previous Technology]

[0002] Over-ear headphones, as the name suggests, are worn on the head and not inserted into the ear canal, unlike in-ear earbuds. They consist of two parts: a signal transmitter and headphones (usually dynamic type) with signal receiving and amplification devices.

[0003] Currently, the sliding arm mechanism of headphones on the market mainly uses a "silicone rubber ring + sliding arm mechanism" to achieve the up-and-down movement of the headphone sliding arm. It mainly utilizes 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 fit to obtain a satisfactory damping force. Therefore, the hardness of the silicone rubber ring and the fitting precision between the silicone rubber ring and the sliding arm are required to be high, resulting in high material costs. Moreover, the silicone rubber ring is prone to producing a jerky feeling when sliding with the metal or plastic sliding arm, resulting in poor damping effect and thus a poor user experience. [Summary of the Invention]

[0004] The purpose of this invention is to provide a damping mechanism with better damping effect and lower material cost.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A damping mechanism includes: a support member having a slide groove and a first through hole communicating with the slide groove; a damping assembly capable of dividing the slide groove into an adjustment chamber and a balance chamber, the balance chamber communicating with the outside, one end of the damping assembly being slidably disposed in the slide groove, the end of the damping assembly extending into the slide groove being a sealing end, the sealing end and the end of the slide groove near the first through hole forming an adjustment chamber, the adjustment chamber communicating with the outside through the first through hole, when the damping assembly slides in the slide groove, the pressure in the adjustment chamber changes, and damping is generated.

[0007] Optionally, the damping mechanism further includes a pressure regulating component, which is located at the first through hole and can regulate the gas flow rate between the regulating chamber and the outside.

[0008] Optionally, the pressure regulating assembly includes a vent, which is sealed to the outside of the first through hole.

[0009] Optionally, the pressure regulating component further includes a fixing member, which is fixed to the support member and presses against the ventilator to adjust the gas flow rate between the regulating chamber and the outside. The fixing member is provided with a second through hole that communicates with the first through hole. One end of the second through hole is set towards the ventilator, and the other end is connected to the outside.

[0010] Optionally, the support member is provided with a connecting groove, and the fastener is threadedly connected to the connecting groove to adjust the pressure of the fastener against the ventilator.

[0011] Optionally, the damping assembly includes a damping element and a sliding element. The damping element is a sealed end and is slidably disposed in the groove. The damping element is sleeved on the sliding element and elastically abuts against the inner wall of the groove.

[0012] Optionally, the sliding member and the inner wall of the slide groove are spaced apart.

[0013] Optionally, the outer wall surface of the damping member elastically abutting against the inner wall of the slide groove is unevenly arranged. Of the sliding member and the damping member, one is provided with a protrusion and the other is provided with a groove that engages with the protrusion.

[0014] Optionally, the damping mechanism further includes a limiting member that protrudes inward from the inner wall of the slide groove so that the damping assembly is stopped by the limiting member when it slides in the slide groove.

[0015] Another object of the present invention is to provide a headset with better damping effect and lower material cost.

[0016] To achieve this objective, the present invention adopts the following technical solution:

[0017] A headset includes a headset body and a damping mechanism as described above, the damping mechanism being disposed on the headset body.

[0018] The beneficial effects of the present invention:

[0019] This invention provides a damping mechanism and headphones. The damping mechanism includes a support member and a damping assembly. The support member has a sliding groove and a first through hole communicating with the sliding groove. The damping assembly can divide the sliding groove into an adjustment chamber and a balance chamber. The balance chamber is connected to the outside. Users can smoothly pull a sliding member out of the sliding groove or push the sliding member into the sliding groove through the balance chamber, reducing the feeling of jamming and improving the user experience. One end of the damping assembly is slidably disposed in the sliding groove. The end of the damping assembly extending into the sliding groove is a sealed end. The sealed end and the end of the sliding groove near the first through hole form an adjustment chamber. The adjustment chamber is connected to the outside through the first through hole, which can ensure that the gas in the adjustment chamber can be smoothly exchanged with the outside, ensuring that the damping assembly can slide smoothly in the sliding groove. When the damping component slides in the groove, the pressure within the regulating cavity changes due to the compression or expansion of the gas. This pressure change dampes the movement of the damping component relative to the support member. This eliminates the need for complex and precise mechanical structures to produce the damping effect, reducing the precision requirements for the fit between the support member and the damping component, and saving material costs. The headphones include a headphone body and a damping mechanism, with the damping mechanism mounted on the headphone body. Through this design, the damping mechanism of this application provides better damping performance and lower material costs.

[0025] As shown in Figures 1-5, 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 communicating with the slide groove 11. The damping assembly 2 can divide the slide groove 11 into an adjustment cavity 111 and a balance cavity 112. The balance cavity 112 is connected to the outside. One end of the damping assembly 2 is slidably disposed in the slide groove 11. The end of the damping assembly 2 extending into the slide groove 11 is a sealing end. The sealing end and the end of the slide groove 11 near the first through hole 12 form the adjustment cavity 111. The adjustment cavity 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 cavity 111 changes, and damping is generated.

[0026] In this embodiment, the support member 1 is provided with a slide groove 11 and a first through hole 12 communicating with the slide groove 11. The damping component 2 can divide 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 out of the slide groove 11 through the balance chamber 112, or push the damping component 2 into the slide groove 11, reducing the feeling of jamming and improving the user experience. One end of the damping component 2 is slidably disposed in the slide groove 11. The end of the damping component 2 that extends into the slide groove 11 is a sealed end. The sealed end and the end of the slide groove 11 near the first through hole 12 form the 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, ensuring that the damping component 2 can slide smoothly in the slide groove 11. When the damping component 2 slides in the groove 11, the pressure within the regulating chamber 111 changes due to the compression or expansion of the gas. This pressure change dampes the movement of the damping component 2 relative to the support member 1. This eliminates the need for complex and precise mechanical structures to produce the damping effect, reducing the precision requirements for the fit between the support member 1 and the damping component 2, and saving material costs. Through the above design, the damping mechanism of this embodiment provides better damping performance and lower material costs.

[0027] The specific structure of the damping mechanism is described below:

[0028] Specifically, as shown in Figures 3 and 4, the damping mechanism also includes a pressure adjustment component 30. The pressure adjustment component 30 is located at the first through hole 12 and can adjust the gas flow rate between the adjustment cavity 111 and the outside. By adjusting the flow rate of the gas through the first through hole 12, the smoothness of sliding and the damping feel 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.

[0029] Specifically, as shown in Figure 4, the pressure regulating component 30 includes a vent 3, which covers the outside of the first through hole 12, allowing the regulating chamber 111 to exchange gas smoothly with the outside through the first through hole 12 and the vent 3. Moreover, by finely designing parameters such as the specific material, pore size, and number of pores of the vent 3, precise control of the gas flow rate can be achieved, thereby contributing to the precise adjustment of the damping feel. The vent 3 can be made of a breathable membrane or a breathable plate, such as a polyurethane breathable membrane or a polytetrafluoroethylene breathable membrane. No further limitations are made on the specific structure and material of the vent 3 here.

[0030] More specifically, as shown in Figure 4, the pressure regulating assembly 30 also includes a fixing member 4. The fixing member 4 is fixed to the support member 1 and presses against the vent member 3 to adjust the gas flow velocity between the regulating chamber 111 and the outside, making the gas flow regulation more precise. It can be understood that when the pressure of the fixing member 4 against the vent member 3 is small, the gas flow velocity through the vent member 3 will be larger, and when the pressure between the fixing member 4 and the vent member 3 is large, the gas flow velocity through the vent member 3 will be smaller. By adjusting the gas flow velocity between the regulating chamber 111 and the outside in this way, the air pressure inside the regulating chamber 111 changes, satisfying the user's requirements for damping feel when the damping assembly 2 moves relative to the slide groove 11. The fixing member 4 has a second through hole 41 that communicates with the first through hole 12. One end of the second through hole 41 is set towards the venting member 3, and the other end is connected to the outside, so that the gas in the regulating cavity 111 can be smoothly exchanged with the outside through the first through hole 12, the venting member 3 and the second through hole 41.

[0031] 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 can be staggered, as long as there is a connecting channel between them to achieve the above-mentioned functions.

[0032] More specifically, in this embodiment, the fixing member 4 is a plastic tail plug, which is not only lightweight but also easy to source and process, resulting in lower cost. In other embodiments, the fixing member 4 is a rubber tail plug. The specific structure and material of the fixing member 4 are not limited here, as long as the above-mentioned functions can be achieved.

[0033] Specifically, as shown in Figure 4, the support member 1 is provided with a connecting groove 13, and the fixing member 4 is threadedly connected to the connecting groove 13 to adjust the pressure of the fixing member 4 against the ventilator 3. This connection method not only has high stability and reliability, but also facilitates the installation and disassembly 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 connecting groove 13 is small, the pressure of the fixing member 4 against the ventilator 3 is small, and the flow velocity of gas through the ventilator 3 will be greater. Therefore, the damping component 2 has less damping resistance when moving relative to the slide 11. When the tightening force between the fixing member 4 and the connecting groove 13 is large, the pressure of the fixing member 4 against the ventilator 3 is large, and the flow velocity of gas through the ventilator 3 will be smaller. Therefore, the damping component 2 has greater damping resistance when moving relative to the slide 11.

[0034] More specifically, one end of the first through hole 12 is connected to the adjustment cavity 111, and the other end is connected to the connecting groove 13. The vent 3 is disposed at one end of the connecting groove 13 near the adjustment cavity 111. When the fixing member 4 is threadedly connected to the connecting groove 13, it can abut against the vent 3 and press the vent 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 adjustment cavity 111 through the second through hole 41, the vent 3 and the first through hole 12. The air flow speed is adjusted by the pressing action of the fixing member 4 on the vent 3 to meet the damping requirements of the damping component 2 when sliding.

[0035] Specifically, as shown in Figures 1-5, the damping assembly 2 includes a damping element 21 and a sliding element 22. The damping element 21 is a sealed end and is slidably disposed in the groove 11. The damping element 21 is sleeved on the sliding element 22 and elastically abuts against the inner wall of the groove 11. The user can pull the sliding element 22 out of the groove 11 or push the sliding element 22 into the groove 11, thereby causing the damping element 21 to slide relative to the inner wall of the groove 11. The damping sensation is generated by the friction between the damping element 21 and the inner wall of the groove 11.

[0036] More specifically, in this embodiment, the damping element 21 is a silicone rubber head, which is the sealing end of the damping assembly 2, and the sliding element 22 is a stainless steel rod. The silicone rubber head is sleeved on one end of the stainless steel rod and slidably disposed in the groove 11. The silicone rubber head can generate sufficient damping force when it contacts the inner wall of the groove 11, thereby slowing down the movement speed of the stainless steel rod and thus producing a better damping feel. In other embodiments, the damping element 21 is a plastic sleeve, and the sliding element 22 is a plastic rod. The plastic sleeve is sleeved on the end of the plastic rod and slidably connected in the groove 11. The damping feel is generated through the friction between the plastic and the inner wall of the groove 11. It is understood that the specific structure and material of the damping element 21 and the sliding element 22 are not limited, as long as the above-mentioned functions can be achieved.

[0037] Specifically, as shown in Figure 4, the slider 22 and the inner wall of the slide groove 11 are spaced apart to form a balance cavity 112. Since users typically hold the slider 22 to pull or push, dirt easily accumulates on the surface of the slider 22. By spaced apart from the inner wall of the slide groove 11, the slider 22 does not come into contact with the inner wall of the slide groove 11, improving the user experience and preventing 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, which can push out dirt from the balance cavity 112 where the slider 22 and the inner wall of the slide groove 11 are spaced apart.

[0038] Specifically, as shown in Figures 4 and 5, the outer wall surface of the damping member 21, which elastically abuts against the inner wall of the slide groove 11, is unevenly arranged to increase the frictional resistance between the damping member 21 and the inner wall of the slide groove 11, thereby improving the damping feel and preventing it from easily falling off. Of the sliding member 22 and the damping member 21, one has a protrusion 221, and the other has a groove 211 that engages with the protrusion 221. This arrangement enhances the connection strength between the damping member 21 and the sliding member 22, preventing relative sliding or separation 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 them.

[0039] More specifically, in this embodiment, the protrusion 221 is disposed on the slider 22, and the slot 211 is formed on the damping member 21. Through the snap-fit ​​cooperation between the protrusion 221 and the slot 211, the damping member 21 can be stably installed on the slider 22. In other embodiments, the protrusion 221 is disposed on the damping member 21, and the slot 211 is formed on the slider 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 in detail.

[0040] Specifically, as shown in Figures 1-5, the damping mechanism also includes a limiting member 5. The limiting member 5 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 limiting 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 is understandable that the inner wall of the limiting 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 dimension 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 cavity 112, when the damping assembly 2 slides to the limiting member 5, since 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 slide groove 11, and the limiting member 5 protrudes inward from the inner wall of the slide groove 11, the damping member 21 is stopped by the limiting member 5 to prevent the damping member 21 from falling off the slide groove 11 due to excessive force.

[0041] More specifically, in this embodiment, the limiting member 5 is a limiting ring made of plastic. The limiting ring limits the sliding of the damping member 21, preventing the damping assembly 2 from disengaging from the slide groove 11. Furthermore, using a plastic limiting ring saves material costs and makes the overall structure lighter. In other embodiments, the limiting assembly 5 is a block structure made of hard silicone, which is not only lighter but also effectively limits the damping assembly 2. It is understood that the specific structure and material of the limiting assembly 5 are not limited, as long as the above-mentioned functions are achieved.

[0042] The specific working process of the damping mechanism is explained below:

[0043] As shown in Figures 1-5, when the damping component 2 slides in the slide groove 11, the pressure inside the regulating cavity 111 changes due to the compression or expansion of the gas. This pressure change in the regulating cavity 111 dampes the movement of the damping component 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 component 21 to slide in the slide groove 11, causing the regulating cavity 111 to draw air from the outside through the vent 3, thus creating a negative pressure damping force. When the user pushes the sliding member 22 back into the slide groove 11, the sealed end compresses the air inside the regulating cavity 111, thus creating a positive pressure damping force. When the user wants to adjust the magnitude of the damping force, by turning the fixing member 4, the pressure of the fixing member 4 against the vent 3 is adjusted, which can regulate the flow rate of gas through the vent 3, thereby affecting the magnitude of the damping force of the damping component 2 when it slides relative to the support member 1.

[0044] As shown in Figures 1-5, this embodiment also provides a headset, which includes a headset body 100 and a damping mechanism. The damping mechanism is disposed on the headset body 100 and can produce a good damping feel. Moreover, the damping feel is mainly achieved by the compression and expansion of the gas in the adjustment cavity 111 through the sealed end, without the need for a complex and precise mechanical structure to produce a damping effect, reducing the fitting accuracy requirements between the support member 1 and the damping component 2, thereby reducing material costs.

[0045] Specifically, as shown in Figures 3 and 4, the earphone body 100 extends in an arc shape. Each earphone body 100 is provided with two damping mechanisms, which are respectively located at both ends of the earphone body 100. The pressure adjustment component 30 can adjust the gas flow rate between the adjustment cavity 111 and the outside, thereby balancing the smoothness and damping feel of the damping component 2 when sliding in the slide groove 11, thus 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 spacing between the sliding member 22 and the inner wall of the slide groove 11 helps to improve the damping effect and prevents dirt on the sliding member 22 from directly contacting the inner wall of the slide groove 11 and affecting the damping feel.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the protection scope of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
