[0030] In the embodiment of the present invention, the telescopic arm 30 and the rotating arm 50 form a rotating adjustment component with an angle adjustment function. The earphone body 60 is rotatably connected to the headband 10 through the rotating adjustment component. The earphone body 60 can be adjusted at multiple angles independently of the headband 10, making it more convenient for the user to wear the rotatable headset, thereby avoiding damage to the headband 10 due to excessive stretching, and reducing the rupture of the headband end of the current headset due to long-term stress. The headset provided by the embodiment of the present invention has a longer service life; at the same time, the earphone body is connected to the headband 10 in a rotatable manner, which can adjust the wearing angle of the earphone body, appropriately reduce the pressure of the earphone body on the user's ear, and further improve the user's wearing comfort.

[0031] In another embodiment of the present invention, Figures 2-3 As shown, the headband 10 of the rotatable headset is provided with a channel 11 inside, the first end of the telescopic arm 30 is slidably connected in the channel 11, and the side of the first end of the telescopic arm 30 is provided with a positioning side 33; the positioning member 20 includes a clamp 21; the clamp 21 is attached to the positioning side 33 of the telescopic arm 30, and the side of the clamp 21 that is attached to the positioning side 33 of the telescopic arm 30 is provided with a positioning protrusion 22 that matches the positioning structure 31, and the positioning protrusion 22 is engaged with the positioning structure 31 to position the telescopic arm 30. The telescopic arm 30 is slidably connected to the headband 10, and the telescopic arm 30 can be extended or retracted into the headband 10. During the sliding process of the telescopic arm 30, the positioning side 33 of the telescopic arm 30 remains in contact with the clamp 21. The user pulls out the telescopic arm 30 to the desired position as required, and relative movement occurs between the positioning structure 31 of the telescopic arm 30 and the positioning protrusion 22. The corresponding position on the positioning structure 31 of the telescopic arm 30 engages with the positioning protrusion 22 of the clamp 21, thereby positioning the telescopic arm 30 and the earphone body.

[0032] In another embodiment of the present invention, Figures 3 to 5 As shown, the clamp 21 of the rotatable headset is provided in an annular structure, and a through hole is provided in the middle of the clamp 21 for the telescopic arm 30 to pass through; the telescopic arm 30 passes through the through hole, and the positioning side surface 33 of the telescopic arm 30 is in contact with the inner side surface of the clamp 21. The clamp 21 is provided in an annular structure to maintain contact with the telescopic arm 30, avoid the clamp 21 from being separated during the sliding process of the telescopic arm 30, improve the stability between the clamp 21 and the telescopic arm 30, and improve the positioning effect of the positioning member 20 on the telescopic arm 30.

[0033] In another embodiment of the present invention, Figures 3 to 5 As shown, the inner side surface of the card 21 of the rotatable headset near the positioning protrusion 22 is provided with two strip grooves 23, which are respectively provided on opposite sides of the positioning protrusion 22, and the strip grooves 23 extend outward and penetrate the outer side surface of the card 21. The card 21 has elastic properties, and the positioning protrusion 22 of the card 21 can produce elastic deformation within a preset range after being pushed by the positioning structure 31. The strip grooves 23 are respectively provided on opposite sides of the positioning protrusion 22, and the supporting force of the part between the two strip grooves 23 is reduced, thereby reducing the force required for the part between the two strip grooves 23 to produce elastic deformation.

When the telescopic arm 30 slides, a positioning groove 310 that is mutually engaged with the positioning protrusion 22 separates from the positioning protrusion 22 as the telescopic arm 30 slides, and the positioning side surface 33 of the telescopic arm 30 pushes the positioning protrusion 22 so that a part of the clamp 21 is elastically deformed outward. As the telescopic arm 30 continues to slide, the next adjacent positioning groove 310 is engaged with the positioning protrusion 22, and the positioning side surface 33 of the telescopic arm 30 removes the pushing force on the positioning protrusion 22, and the part of the clamp 21 that is elastically deformed returns to its original state. The positioning structure 31 and the positioning protrusion 22 are engaged or separated according to this principle, thereby realizing the positioning function of the telescopic arm 30.

[0035] In another embodiment of the present invention, Figure 2As shown, the positioning member 20 of the rotatable headset includes a fixed shell 24; the fixed shell 24 includes a left shell 240 and a right shell 241 that are arranged opposite to each other; the left shell 240 and the right shell 241 are spliced ​​with each other to fix the clamp 21 between the left shell 240 and the right shell 241, and the left shell 240 and the right shell 241 can be detachably installed on the end of the headband 10. The left shell 240 and the right shell 241 are connected in a detachable manner, which is convenient for assembly and maintenance, and the structure is practical.

[0036] In another embodiment of the utility model, the fixed shell 24 of the rotatable headset is provided with a first wire hole (not shown) for the wire to pass through, and the earphone body 60 is provided with a second wire hole (not shown). The reserved first wire hole and second wire hole are for easy installation of the wire.

[0037] In another embodiment of the present invention, Figure 3 As shown, the angle between the connecting piece 32 of the rotatable headset and the second end of the telescopic arm 30 is in the range of 85° to 100°.

The gasket 405 is added to reduce the gap between the connecting piece 32 and the second positioning protrusion 404, thereby reducing the shaking of the rotating arm 50 and improving the stability of the rotating arm 50.

[0040] In another embodiment of the present invention, the rotating arm 50 of the rotatable headset is arranged in a semicircular structure, and a rotating shaft is respectively installed at both ends of the rotating arm 50, and the rotating shaft is rotatably connected to the earphone body 60.
