The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] See also Figure 1 and Figure 2 The rotating assembly structure of the headset of the present invention includes a fixing member 100, a rotating member 200, a gasket assembly 300 and a fastening assembly 400.

[0038] The rotating member 200 can rotate based on the fixing member 100. The gasket assembly 300 is used to provide a rotating feel and absorb the rotating force during the rotation of the rotating member 200. The fastening assembly 400 is used to fasten and assemble the fixing member 100, the rotating member 200 and the gasket assembly 300 together in the axial direction.

[0039] The fastening assembly 400 includes a fastener 1 410 and a fastener 2 420 that are locked together. One end of the fastener 1 410 passes through the fixing member 100 , the rotating member 200 and the gasket assembly 300 in sequence and is connected to the fastener 2 420 .

[0040] After the fixing member 100, the rotating member 200 and the gasket assembly 300 are connected in series in sequence by fastener 1 410, fastener 2 420 is matched with fastener 1 410 for locking connection, so that the fixing member 100, the rotating member 200 and the gasket assembly 300 are assembled together, so that the rotating member 200 can rotate based on the fixing member 100, and the gasket assembly 300 can play a role in adjusting the rotation feel.

[0041] The gasket assembly 300 at least includes a metal gasket 1 310 , a metal bow-shaped gasket 1 320 , and a metal gasket 2 330 , wherein the metal bow-shaped gasket 1 320 is located between the metal gasket 1 310 and the metal gasket 2 330 .

[0042] Metal gasket 1 310 is used to rotate and contact with the rotating part 200 and transmit the rotational force to metal bow-shaped gasket 1 320. Metal gasket 2 330 is used to contact fastener 2 420 and provide support for metal bow-shaped gasket 1 320. Metal bow-shaped gasket 1 320 is used to absorb the rotational buffering force of the rotating part 200, so that the whole plays a role in adjusting the rotational feel.

[0043] The rotating combination structure of the headset provided in this embodiment adopts a metal gasket 1 310, a metal bow-shaped gasket 1 320 and a metal gasket 2 330 made of metal material. When the rotating part 200 is rotated based on the fixed part 100, the gasket made of metal is not easy to wear, which is beneficial to improving the mechanical service life of the product; a metal bow-shaped gasket 1 320 is arranged between the metal gasket 1 310 and the metal gasket 2 330. The design of the metal bow-shaped gasket can elastically buffer and absorb the buffering force when the rotating part 200 rotates, thereby adjusting the rotation feel and making it smooth to use.

[0044] Embodiment 2:

[0045] The difference between this embodiment and embodiment 1 is that the rotating assembly structure of the headset of this embodiment further includes a second metal arched gasket 340, see Figure 3 and Figure 4 .

[0046] The gasket assembly 300 also includes a metal bow-shaped gasket 340, which is located between the metal bow-shaped gasket 1 320 and the metal gasket 2 330. Two metal bow-shaped gaskets are arranged between the metal gasket 1 310 and the metal gasket 2 330, which can play a better elastic buffering and absorption role, thereby better adjusting the rotation feel.

[0047] In some embodiments, the protruding direction of the metal arched gasket 1 320 and the protruding direction of the metal arched gasket 2 340 are arranged to face each other, so as to absorb the rotation buffer force in a concentrated manner and play a better elastic buffering and absorbing role.

[0048] It can be understood that a through hole for the fastener 410 to pass through is formed in the middle of the metal gasket 1 310, the metal gasket 2 330, the metal bow-shaped gasket 1 320 and the metal bow-shaped gasket 2 340, wherein the metal gasket 1 310 and the metal gasket 2 330 are both flat, the metal gasket 1 310 is used to abut against the rotating member 200, the metal gasket 2 330 is used to abut against the fastener 2 420, and the metal bow-shaped gasket 1 320 and the metal bow-shaped gasket 2 340 are peripherally oriented. The middle is gradually arched, so its height gradually increases with the change from the periphery to the middle position, and the protruding direction of the metal bow-shaped gasket 1 320 and the protruding direction of the metal bow-shaped gasket 2 340 are set to be opposite to each other, so as to concentrate the absorption of the rotation buffer force of the rotating part 200. At the same time, with the help of the outer part of the metal bow-shaped gasket 1 320 contacting with the metal gasket 1 310, and the outer part of the metal bow-shaped gasket 2 340 contacting with the metal gasket 2 330, a better supporting and fixing effect is played.

[0049] Embodiment 3:

[0050] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the metal gasket 1 310 and the metal gasket 2 330 of the utility model. Figure 5 and Figure 6 .

[0051] A plurality of first grooves 311 are formed on the surface of the metal gasket 310 that contacts the metal bow-shaped gasket 320. The plurality of first grooves 311 are evenly or unevenly spaced. The first grooves 311 are provided to reduce the contact area between the metal gasket 310 and the metal bow-shaped gasket 320, which can reduce friction and prevent slipping.

[0052] For example, the metal gasket 310 is a circular gasket structure, in the middle of which a through hole for the fastener 410 to pass through is opened, and in different areas of its edge portion, there are multiple first grooves 311 distributed at even intervals and uneven intervals.

[0053] There is no specific limitation on the shape and data of the first groove 311, which can be adjusted according to actual needs. For example, the first groove 311 is a circular groove, and the number of the first grooves 311 is 16, and 3 or 2 are distributed in groups at intervals.

[0054] In some embodiments, fastener 1 410 is a screw and fastener 2 420 is a nut. One end of the screw is passed through the fixing member 100, the rotating member 200 and the gasket assembly 300 in sequence and then locked with the nut. The fixing member 100, the rotating member 200 and the gasket assembly 300 are fastened in a detachable manner to facilitate assembly and disassembly.

[0055] In some embodiments, a plurality of second grooves 331 are formed on the surface of the metal gasket 330 that contacts the fastener 420. The plurality of second grooves 331 are evenly or unevenly spaced. The second grooves 331 are provided to reduce the contact area between the metal gasket 330 and the fastener 420. On the one hand, this can reduce friction, and on the other hand, it can also provide an anti-slip effect.

[0056] For example, the second metal gasket 330 is a circular gasket structure, in the middle of which a through hole for the fastener 410 to pass through is opened, and in different areas of its edge portion, there are multiple second grooves 331 distributed at even intervals and uneven intervals.

[0057] There is no specific limitation on the shape and data of the second groove 331 , which can be adjusted according to actual needs. For example, the second groove 331 is a circular groove, and the number of the second grooves 331 is 16, and 3 or 2 are distributed in groups at intervals.

[0058] Embodiment 4:

[0059] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the fixing member 100 and the rotating member 200 of the utility model. Figure 7 and Figure 8 .

[0060] The fixing member 100 is a metal fixing member 100 , and the rotating member 200 is a metal rotating member 200 . The fixing member 100 and the rotating member 200 made of metal are not easy to wear and tear and the overall service life of the rotating combination structure is increased.

[0061] For example, the fixing member 100 and the rotating member 200 are made of metal materials such as copper, iron, steel, aluminum or alloy.

[0062] A boss 210 is formed on one end of the rotating member 200 close to the fixed member 100, and a recess 110 is formed on the fixed member 100 for rotationally connecting with the boss 210. The cooperation between the boss 210 and the recess 110 facilitates the alignment and assembly of the fixed member 100 and the rotating member 200, and also serves as a rotation guide.

[0063] Specifically, a protrusion 211 is provided on the boss 210, and a slide groove 111 for rotationally connecting with the protrusion 211 is provided on the recess 110. The slide groove 111 limits the rotation distance of the protrusion 211 so that the rotating member 200 rotates within the set rotation distance to meet the rotation requirements during actual use.

[0064] In some embodiments, the fixing member 100 is provided with a first connection hole 120 for connecting to the headphone headband, and the rotating member 200 is provided with a second connection hole 220 for connecting to the ear shell. The first connection hole 120 and the second connection hole 220 are used to facilitate alignment and connection with the headphone headband and the ear shell, thereby improving assembly convenience and stability.

[0065] For example, the fixed member 100 and the rotating member 200 are approximately cylindrical, and are rotationally connected to each other in the axial direction. The first connecting hole 120 penetrates inwardly along the outer circumference of the fixed member 100, and the second connecting hole 220 penetrates inwardly along the outer circumference of the rotating member 200.

[0066] The rotating combination structure of the headset provided by the utility model adopts a metal gasket 1, a metal bow-shaped gasket 1 and a metal gasket 2 made of metal materials. When the rotating part is rotated based on the fixed part, the gasket made of metal is not easy to wear, which is beneficial to improving the mechanical service life of the product. A metal bow-shaped gasket 1 is arranged between the metal gasket 1 and the metal gasket 2. The design of the metal bow-shaped gasket can elastically buffer and absorb the buffering force when the rotating part rotates, thereby adjusting the rotation feel and making it smooth to use.
