Referring to fig. 1, an embodiment of the present invention provides a headphone. The headset comprises a head band 1, a headset body 2 and a connecting device 3, wherein the head band 1 is connected with the headset body 2 through the connecting device 3; the connecting means 3 comprise a sleeve 31.

Specifically, referring to fig. 2, the headband 1 is provided with an upper cover rotating shaft 11, and the first end surface of the sleeve 31 is connected to the end surface of the upper cover rotating shaft 11. For example, a bottom is provided at a first end face of the sleeve 31. The upper cover rotating shaft 11 and the sleeve 31 are sleeved outside the middle rotating shaft 4, a first section of the middle rotating shaft 4 is positioned in the upper cover rotating shaft 11, and a second section of the middle rotating shaft passes through the through hole at the bottom. Preferably, the middle shaft 4 is made of a firm and wear-resistant metal material. The sleeve 31 can rotate around the middle rotating shaft 4, a stop piece 5 is sleeved at the position, close to the end, of the second section of the middle rotating shaft 4, a gasket set is arranged between the sleeve 31 and the stop piece 5, the gasket set comprises a first wear-resistant gasket, a framework gasket and an elastic gasket which are combined together, and the first wear-resistant gasket is in contact with the inner side of the bottom of the sleeve.

The middle rotating shaft 4 is also sleeved with a damping washer 9, and the damping washer 9 is configured to form damping force with the bottom of the sleeve. For example, the damping washer 9 contacts the wall of the through hole at the bottom to form a friction force, thereby forming a damping force.

The sleeve 31 is stably fixed on the middle rotating shaft 4 through the stop piece 5, and a gasket group is added between the stop piece 5 and the sleeve 31. The elastic gasket 8 can elastically deform in the axial direction, and tolerance from parts such as a sleeve, a stop piece, a middle rotating shaft and the like is absorbed, so that assembly errors are reduced.

As shown in fig. 3, in one embodiment, the second section outer side wall of the middle rotating shaft 4 has a first clamping groove 41 and a second clamping groove 42, and the stop member 5 is disposed in the first clamping groove 41; the damping washer 9 is arranged in the second clamping groove 42.

In order to improve the wear resistance of the gasket set, a plurality of first wear-resistant gaskets 6 can be arranged, likewise, in order to improve the stabilization effect of the gasket set, a plurality of framework gaskets 7 can be arranged, and a plurality of elastic gaskets 8 can be arranged to improve the absorption effect of the gasket set on the tolerance of parts. For example, the skeleton pad 7 is located between the first wear pad 6 and the resilient pad 8. So that the resilient pad 8 is in contact with the stop 5, so that the resilient pad 8 can absorb tolerances more effectively.

In one embodiment, the material of the first wear-resistant pad 6 is PTFE, and the wear-resistant pad of PTFE has high hardness and excellent high temperature resistance, wear resistance, scratch resistance and corrosion resistance, and of course, the material of the first wear-resistant pad 6 may also be POM; the framework gasket 7 is made of stainless steel, and of course, the framework gasket 7 can also be made of aluminum alloy or the like; the elastic pad 8 is made of rubber, for example, fluororubber, and the fluororubber has good durability. Of course, the elastic pad 8 may be made of silicone rubber; the damping washer 9 is made of fluororubber, and of course, the damping washer 9 may also be made of silicone rubber.

In one embodiment, the headband 1 has an annular groove 111 at a position corresponding to the bottom of the sleeve 31, the bottom has an annular protrusion 311 matched with the annular groove 111, and the annular protrusion 311 is in fit connection with the annular groove 111; the annular protrusion 311 is inserted into the annular groove 111, and when the sleeve 31 rotates around the central rotation shaft 4, the annular protrusion 311 rotates along the annular groove 111 in the annular groove 111, so as to ensure the stability of rotation.

In one embodiment, a second wear pad 10 is disposed between the bottom and the headband 1, and similarly, the second wear pad 10 may be made of PTFE or POM. The provision of the second wear pad 10 is effective to reduce the frictional forces between the sleeve 31 and the headband 1 during rotation.

Further, the stop piece 5 is a C-shaped snap ring. The C-shaped clamping ring is very convenient to connect and detach, can lock the sleeve 31 stably, and can prevent the sleeve 31 from displacing along the axial direction of the middle rotating shaft 4 when the sleeve 31 rotates around the middle rotating shaft 4.
