The upper rotation bracket is fixed on the lower rotation bracket, and the microphone rod end is fixed on the upper rotation. Between the bracket and the lower rotating bracket, a microphone line is arranged in the microphone rod, and passes through the top of the upper rotating bracket into the space under the cover sheet, and is connected with the audio input cable;

The buckle is fixed on a fixing post in the earphone shell, the lower rotating bracket is rotatably mounted on the fixing post, and is located under the cover sheet, the cover sheet is fixed on the fixing post by screws, and the buckle is provided with two sets of symmetrical projections. A tooth structure. Each set of convex tooth structures includes three convex teeth, and the grooves are formed between the convex teeth. The metal needle is fixed on the upper rotating bracket. The O-ring is arranged between the lower rotating bracket and the fixing post of the earphone shell.

As a further solution of the present utility model, a microphone is provided at the end of the microphone rod, and the headset includes an upper cover, a lower cover, and a capacitive microphone. The upper cover and the lower cover are fixed, and the capacitive microphone is fixed between the upper cover and the lower cover. And connect it with the microphone.

As a further solution of the present utility model, the O-ring is provided with two groups.

Compared with the prior art, the utility model has the beneficial effects that the utility model adopts a metal pin and a snap rotation positioning structure, and a method of fixing the friction resistance of the rotation bracket. The design of the mechanical structure can make the earphone with a microphone The user can easily turn the microphone stick and stay in the proper position, so that the voice quality is stable during a call, and it is convenient for the user to retract the microphone stick. In addition, the microphone cord enters the earphone shell through the top hole in the upper rotating bracket, which is difficult to make The microphone wire has problems such as bending and breaking, which prolongs the service life.

detailed description

In the following, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making creative work belong to the protection scope of the present invention.

Please refer to FIGS. 1-4. In the embodiment of the present invention, a headset microphone rotation structure includes: an upper rotating bracket 6, a lower rotating bracket 7, a metal needle 12, a buckle 11, an O-ring 13, and a cover 8 The upper rotating bracket 6 is fixed on the lower rotating bracket 7 and the microphone rod 5 The end is fixed between the upper rotary bracket 6 and the lower rotary bracket 7. A microphone wire 4 is arranged in the microphone rod 5, and passes through the top of the upper rotary bracket 6 to enter the space below the cover sheet 8, and is connected to the audio input line 14 to realize voice Input function: when the rotary bracket rotates, the extended microphone wire 4 rotates with the upper rotary bracket 6, so that it is not easy to cause bending, tensile damage, etc. to the microphone wire 4, and it is not easy to break;

The buckle 11 is fixed on a fixing post in the earphone shell 9, and the lower rotating bracket 7 is rotatably mounted on the fixing post and is located under the cover sheet 8. The cover sheet 8 is fixed on the fixing post by screws 10. Two sets of symmetrical convex tooth structures 111 are arranged on each, and each group of convex tooth structures 111 includes three convex teeth, and the grooves 112 are formed between the convex teeth to form a total of 4 slots. The metal needle 12 is fixed on the upper rotating bracket 6. When turning the rotating bracket, the microphone rod 5 and the metal needle 12 will be driven to rotate. The metal needle 12 is respectively locked in different slots to fix the microphone rod 5. For example, when the user wears the microphone rod to his right ear, When the metal needle 12 is stuck in the upper right position, the microphone rod 5 is retracted.
