Description

Technical Field

[0002] Headphones have the advantages of good sound field, excellent sound quality, high comfort, avoiding scratches on the ear canal, protecting the eardrum, etc., and are therefore deeply loved by users. Headphones mainly include headbands, ear shells, etc. When in use, the headband is located on the user's head, and the ear shells are located outside the two ears. In order to adapt to the head shapes of different users, the length of the headband needs to be adjustable. The headband generally includes a shell and a sliding member that slides with the shell, and the ear shells are connected to the sliding member.

[0003] During adjustment, in order to ensure the damping feel of the sliding part during the sliding process, a damping mechanism is generally set between the sliding part and the shell. The existing damping mechanisms are mostly of the following two types: one is the coordination of the spring sheet set on the sliding part and the slot structure of the shell. The spring sheet in this structure needs a certain size to provide sufficient elastic force. Therefore, the space requirement for the shell is large, and the spring sheet is generally made of metal, and the friction between the spring sheet and the shell is prone to noise. The other is to set soft parts such as silicone on the sliding part and the shell of hard plastic or metal material to directly generate friction to generate damping, but the deformation of the soft parts is difficult to control, resulting in unstable damping, affecting the user experience.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0053] like Figures 1 to 10As shown, this embodiment provides a damping mechanism for headphones, which reduces the size of the overall mechanism and reduces the possibility of noise. The damping mechanism for headphones includes a housing 100, a sliding arm 200, a sliding member 300 and a damping member 400, wherein at least a portion of the housing 100 is arc-shaped; when applied to headphones, it can adapt to the user's head shape. The sliding arm 200 is arc-shaped and fixed in the housing 100, and the sliding arm 200 has a long strip of first damping part 211; the sliding member 300 is movably constrained to the housing 100; the damping member 400 is connected to the sliding member 300 and can move synchronously with the sliding member 300, and the damping member 400 has a second damping part 421 that can be press-fitted with the first damping part 211, and when the sliding member 300 reciprocates relative to the housing 100, friction is generated between the second damping part 421 and the first damping part 211. The sliding arm 200 and the damping member 400 are both made of polyoxymethylene (POM for short), and the sliding arm 200 and the housing 100 are made of different materials.

[0054] The first damping portion 211 and the second damping portion 421 are both arc-shaped surfaces. Along the extension direction of the sliding arm 200 , the curvature of the first damping portion 211 and the second damping portion 421 is the same as the curvature of the sliding arm 200 to achieve surface contact between the two.

[0055] Since the sliding arm 200 and the damping member 400 are both made of POM, a damping feeling can be generated during the sliding process by simply pressing the two together. Compared with the spring sheet, there is no need to set up too much space, which is conducive to reducing the size of the damping mechanism. In addition, since the material property of POM is self-lubricating, the possibility of noise during the friction process is reduced. In addition, POM has a high hardness, good wear resistance, and is not easy to deform, so it is easier to ensure the stability of the damping feeling.

[0056] To further reduce the size, in some embodiments, the sliding arm 200 is provided with a sliding groove 212, and the sliding member 300 includes a sliding external connection portion 310 and a sliding matching portion 320. The sliding matching portion 320 is arc-shaped and consistent with the arc of the sliding arm 200. The sliding matching portion 320 is arranged in the sliding groove 212 and is fixedly connected to the damping member 400. The sliding external connection portion 310 is used to connect the ear shell. To increase the strength of the entire damping mechanism, the outer diameter of the cross-section of the sliding arm 200 is appropriately increased. However, to reduce the size of the damping mechanism, the sliding groove 212 is provided on the sliding arm 200, and the sliding matching portion 320 is arranged in the sliding groove 212, so that the sliding member 300 can overlap with the sliding arm 200 in a direction perpendicular to the extension direction of the damping mechanism, thereby reducing the cross-sectional area of ​​the damping mechanism and reducing the volume.

[0057] Combination Figure 2 and Figure 3As shown, in order to ensure the balance of damping and avoid deflection of the sliding member 300 during the sliding process, in some embodiments, the two opposite side walls at the opening of the sliding groove 212 are relatively raised to form a closing portion 213, and a part of 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 installed on the upper side of the sliding member 300 and partially extends out of the sliding groove 212. The friction portion 420 is located on the outer side 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. Two second damping portions 421 are formed on the bottom surface of the friction portion 420. The second damping portion 421 is crimped to the first damping portion 211, and the sliding member 300 abuts against the bottom surface of the receiving opening 213. 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 arm 200 more stable, the friction force more balanced, and easier to control; at the same time, the contact area is increased, so that the wear rate is further reduced, and the size of the friction force between the two is more likely to remain unchanged, that is, the damping feel is more likely to remain unchanged, thereby improving the user experience.

[0058] In some embodiments, one of the top surface of the sliding arm 200 and the bottom surface of the damping member 400 is provided with a sliding protrusion 214, and the other is provided with a sliding groove 422, and the sliding protrusion 214 is slidably disposed in the sliding groove 422. Among them, the top of the sliding arm 200 is provided with two strip-shaped sliding protrusions 214 whose extension direction is parallel to the extension direction of the sliding groove 212, and the two sliding protrusions 214 are respectively provided on both sides of the sliding groove 212, and the damping member 400 is provided with two sliding grooves 422, and the two sliding grooves 422 are correspondingly slidably matched with the two sliding protrusions 214. 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; the first damping portion 211 has a larger elastic variation space, thereby improving the service life while ensuring the damping effect.

[0059] The sliding protrusion 214 is arranged at the top of the closing portion 213 , which 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.

[0060] In other embodiments, the inner wall of the sliding groove 422 and the side wall of the sliding protrusion 214 are pressed and matched to generate friction. In the extension direction of the sliding arm 200, under the premise that the length of the damping member 400 is limited, the damping effect is improved as much as possible, thereby reducing the material used for the damping member 400 and reducing the cost. Preferably, the two opposite side walls of the two sliding grooves 422 with a longer distance abut against the two opposite side walls of the two sliding protrusions 214. In other words, the front side wall of the sliding groove 422 on the front side abuts against the front side wall of the front sliding protrusion 214; the rear side wall of the sliding groove 422 on the rear side abuts against the rear side wall of the rear sliding protrusion 214. This arrangement can generate damping between the damping member 400 and the sliding arm 200, and can make the upper side opening of the sliding groove 212 tend to gather, and the sliding arm 200 along the cross section perpendicular to its own extension direction is U-shaped as a whole, with a bow shape, so that the tension is maintained as a whole to maintain the stability of friction damping.

[0061] Combination Figure 8 and Fig. 9 As shown, the sliding arm 200 is provided with a first stopper 215 and a second stopper 221 at intervals, and the sliding member 300 is stopped when the damping member 400 abuts against the first stopper 215 or the sliding member 300 abuts against the second stopper 221 during the sliding process along the sliding arm 200. The housing 100 is made of plastic, and since the sliding arm 200 and the damping member 400 are both made of POM, POM can provide a stable buffering effect due to its high strength, high rigidity, high wear resistance, and flexible movement performance.

[0062] In some embodiments, the sliding arm 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 penetrates the sliding body 210 to facilitate mold opening. The stopper 220 is provided at one end of the sliding groove 212 to block the end opening of the sliding groove 212 and improve the strength of the sliding body 210. The other end of the sliding groove 212 is provided with a stopper ring. The stopper ring forms a first damping portion 211. The outer diameter of the sliding member 300 is greater 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 the second limiting portion 221 is provided on the stopper 220. When the sliding member 300 shrinks to the inside of the sliding groove 212, it abuts against the stopper ring to achieve limiting, and the stopper ring is made of POM material.

[0063] The sliding body 210 is provided with a sliding groove 212, the sliding member 300 is arranged in the sliding groove 212, the stopper 220 is a cylindrical structure and is sleeved on one end of the sliding body 210, and the end of the stopper 220 is provided with an integrally formed stopper plate, at least part of the stopper plate is located in the sliding groove 212, and the stopper plate is a second limiting portion 221, and the damping member 400 is provided with a buffer portion protruding on one side of the second limiting portion 221 for abutting against the second limiting portion 221. The stopper 220 can be made of metal. In the left and right directions, the buffer portion and the mounting hole are arranged at intervals. The setting of the buffer portion can abut against the stopper 220 when the sliding member 300 moves out of the sliding groove 212, avoiding impact on the damping horizontal portion 423, ensuring the stability of the damping vertical portion 424, and thus facilitating the damping feel.

[0064] The damping member 400 protrudes outwardly toward one side of the second limiting portion 221 to form a strip-shaped buffer block 430 to form a buffer portion. The buffer block 430 extends in the vertical direction, and at least two buffer blocks 430 are provided. The two buffer blocks 430 are spaced apart in a direction perpendicular to the extension direction thereof, that is, the two buffer blocks 430 are spaced apart in the front-rear direction.

[0065] The sliding arm 200 extends in the left-right direction and is bent downward, and the width direction of the sliding arm 200 is the front-back direction.

[0066] The side wall of the stop member 220 is formed by punching to have a strip-shaped stop portion 222 extending toward the inside of the stop member 220, and the outer side wall of the sliding body 210 is provided with a stop groove 216 and a stop protrusion 217, and the stop groove 216 and the stop protrusion 217 are arranged at intervals along the extension direction of the sliding groove 212, and 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, and the stop member 220 abuts against the stop protrusion 217. During installation, the stopper 220 needs to be sleeved on the sliding body 210, and then pushed so that the stopper 222 and the sliding body 210 are turned outward when they are in contact. When the stopper 222 moves to the stopper groove 216, under the action of its own elastic force, the end of the stopper 222 enters the stopper groove 216, and the end of the stopper 220 and the stopper protrusion 217 are in contact, so as to complete the axial limit of the stopper 220 and the sliding body 210. Further, at least two stopper grooves 216 and stopper 222 are provided respectively, and they are arranged one by one. Each stopper 222 is arranged at intervals around the circumference of the stopper 220 to achieve the circumferential limit of the stopper 220. At the same time, it is prevented that the stopper plate and the side wall of the opening of the sliding groove 212 come into contact, thereby affecting the limit accuracy.

[0067] Combination Figure 6 and Figure 7As shown, since the sliding member 300 is a long strip structure, when in use, the housing 100 needs to be fixed, and the sliding member 300 is held by hand to pull outward or push inward so that the sliding member 300 moves relative to the housing 100. Due to manual operation, it is inevitable that the force is uneven. In order to prevent the force from affecting the abutment between the damping member 400 and the sliding arm 200, thereby affecting the damping feeling between the two, in some embodiments, the housing 100 has a cavity and a sliding channel connecting the cavity, and the damping mechanism for the headset also includes a guide assembly 500, the guide assembly 500 has a guide slide 511, the guide assembly 500 is arranged in the sliding channel, the sliding member 300 is inserted into the guide slide 511, and can slide relative to the guide assembly 500 under the guiding action of the guide slide 511, and at least the part of the sliding member 300 connected to the damping member 400 is located inside the cavity. This arrangement constrains the sliding member 300 by the guide assembly 500. Even if the force direction and the sliding direction are not parallel, forces other than the push-pull force will not be transmitted to the damping member 400, thereby ensuring the pressure stability between the damping member 400 and the sliding arm 200, thereby improving the stability of the damping feel.

[0068] To adapt to the structure of the headset, in some embodiments, the guide slide 511 is arc-shaped, and the sliding member 300 includes a sliding matching portion 320 and a sliding external connection portion 310 connected to each other. The sliding matching portion 320 is slidably arranged inside the guide slide 511. The sliding matching portion 320 is arc-shaped, and the sliding matching portion 320 and the sliding channel have the same curvature. This arrangement allows the entire damping mechanism to be placed and fit on the top of the user's head when in use.

[0069] In some embodiments, the guide assembly 500 includes a guide member 510 of a cylindrical structure and a connecting member 520, wherein a guide slideway 511 is disposed in the guide member 510, and the connecting member 520 is arranged to be able to detachably connect the guide member 510 and the housing 100. This arrangement facilitates assembly and improves assembly efficiency; at the same time, when facing different models of sliding members 300, only the guide member 510 needs to be replaced, and the connecting member 520 can be universal, thereby reducing the mold opening cost.

[0070] In order to facilitate connection and improve connection efficiency, in some embodiments, the guide member 510 is partially inserted into the sliding channel, and the outer wall of the guide member 510 located outside the sliding channel is concavely provided with a first clamping groove 512, and the housing 100 is provided with a second clamping groove 110.
