Referring to fig. 1 and fig. 3 together, the headphone according to the present invention will now be described. The headset comprises a headset bracket 1, two ear muffs 2 and a rotating arm 3. Wherein two earmuffs 2 set up respectively at the both ends of earphone holder 1, and rotor arm 3 sets up the tip at each earmuff 2 and earphone holder 1 to link together earphone holder 1 and earmuff 2. The rotating arm 3 comprises a connecting head 31 and a connecting shaft 32, the connecting shaft 32 is arranged at one end of the connecting head 31 and extends along the length direction of the earphone bracket 1, and the connecting head 31 is rotatably connected with the earphone bracket 1, so that the ear muffs 23 are folded relative to the earphone bracket 1, the size of the headset is reduced, and the headset can be conveniently stored and carried. The connecting shaft 32 is located on the end surface of the connecting head 31, so that the connecting shaft 32 and the connecting head 31 form a tight connection, and the connecting shaft 32 is conveniently and stably fixed on the connecting head 31. In particular, the connecting shaft 32 has a friction member 33 extending circumferentially, and correspondingly, the ear muff 2 comprises a shell 21 and a support 22 arranged on the shell 21, and the support 22 comprises a support base 23 and a mounting base 24, wherein the mounting base 24 is fixed on a side of the support base 23 away from the earphone holder 1, so that the mounting base 24 tightly covers the support base 23. The supporting seat 23 includes a supporting plate 25, a through hole 251 is provided on the supporting plate 25, an arc seat 252 is convexly provided on one side of the supporting plate 25 departing from the through hole 251 of one side of the earphone holder 1, so that the friction member 33 can pass through the through hole 251 and extend into the arc seat 252, an arc block 241 used with the arc seat 252 is provided on the mounting seat 24, an opening (not shown) is provided on the arc block 241 corresponding to the position of the mounting seat 24, and a mounting groove 242 for the friction member 33 to be fitted into is provided on the inner side surface of the arc block 241. So structure, friction piece 33 on connecting axle 32 alright pass through hole 251 on the extension board 25 and the trompil on the arc piece 241, and get into in the arc seat 252, and install in the mounting groove 242 of arc piece 241, and because the surface of friction piece 33 is comparatively crude, then the contact department of friction piece 33 and mounting groove 242 just can produce great friction, there is great damping between connecting axle 32 and the ear muff 2 promptly, so the relative earphone support 1 of ear muff 2 rotates more steadily, and after the relative earphone support 1 of ear muff 2 rotates to suitable angle, ear muff 2 just can lose the effect of external force this moment, thereby make ear muff 2 and earphone support 1 relative positioning because of the existence of damping, so that ear muff 2 laminates the people's face better. The ear cup 2 is divided into the case 21 and the holder 22, and the holder 22 is divided into the mount 24 and the support base 23, so that the friction member 33 can be easily mounted.

Referring to fig. 1 and fig. 3 together, the headphone according to the present invention will now be described. The outer peripheral surface of the friction member 33 is provided with a stop flange 331 in a protruding manner, the inner side surface of the arc seat 252 and the side wall of the through hole 251 are provided with slots 253, the slots 253 are axially extended along the through hole 251, the slots 253 can be penetrated by the stop flange 331, the inner side surface of the arc seat 252 is provided with a first arc-shaped slot 254 corresponding to the mounting groove 242 for the stop flange 331 to be rotatably arranged, the first arc-shaped slot 254 is communicated with the slots 253, and stop surfaces 243 are formed on two end surfaces of the arc block 241. The stop surface 243 can be used to stop the stop flange 331 so as to limit the rotation angle of the connecting shaft 32, and since the first arc-shaped slot 254 is communicated with the slot 253, the rotation stop flange 331 can pass through the slot 253 and extend into the first arc-shaped slot 254. With such a structure, after the stop flange 331 of the friction member 33 passes through the slot 253 and is rotatably disposed into the first arc-shaped groove 254, and after the ear muffs 2 rotate around the connecting shaft 32 to a specific angle, the stop surface 243 of the arc-shaped block 241 will abut against the stop flange 331 on the friction member 33, so as to limit the rotation path of the friction member 33, that is, the ear muffs 2 cannot be arbitrarily opposite to the earphone holder 1, and thus other accessories such as an earphone cord connected to the earphone holder 1 can be effectively protected.

Further, please refer to fig. 1 to 5, which are specific embodiments of the headset according to the present invention. The protruding 35 of friction ring that is equipped with of circumference of connecting axle 32, the protruding 35 of friction ring is located the one end that is close to earphone holder 1 on the connecting axle 32, protruding 35 of friction ring goes up along the axial of connecting axle 32 and stops the protruding 351 of being equipped with of position that corresponds of flange 331, set up on the lateral wall of through-hole 251 and supply positioning flange 351 to rotate the second arc wall 255 of putting into, the one end and the fluting 253 of second arc wall 255 are linked together, form the cooperation between first arc wall 254 and the second arc wall 255 and place the arc brace 255 between positioning flange 351 and the flange 331 of stopping, stop flange 331 of friction piece 33 and the positioning flange 351 of the protruding 35 of friction ring support the both sides at arc brace 255 respectively promptly, be favorable to connecting axle 32 to stabilize the ear muff and install in 2. With such a structure, when the friction member 33 is installed, the stop flange 331 of the friction member 33 can be rotated and slid into the arc seat 252 from the intersection of the first arc-shaped groove 254 and the slot 253, so as to facilitate the installation of the friction member 33. In addition, when the stop flange 331 of the friction member 33 rotates on the first arc-shaped groove 254, the positioning flange 351 of the friction ring protrusion 35 also slides on the first arc-shaped groove 254, and since the friction member 33 and the friction ring protrusion 35 both contact with the arc-shaped branch 255, the friction between the connecting shaft 32 and the ear muffs 2 is increased, so that the rotation of the ear muffs 2 relative to the earphone holder 1 is more stable.

Further, please refer to fig. 3 to fig. 6, which are specific embodiments of the headset according to the present invention.
