Detailed Description

The utility model is further described with reference to the following examples.

In an embodiment of the stretching and rotation limiting structure of the headphone according to the present invention, as shown in fig. 1 to 4, the headphone includes a headband 1, a hinge post 4, and an earmuff 2.

In this embodiment, in order to facilitate the continuous maintenance of the earphone, the earmuff 2 includes a bottom cover 21 and an ear cover 22 detachably connected to the bottom cover 21, and the detachable connection mode can be realized by a clamping structure or a screw fixing mode, and can be specifically selected according to actual requirements. Be equipped with sound generating unit 23 between bottom 21 and the ear lid 22, sound generating unit 23 can be fixed through the mode of adhesion, of course, can also set up other electronic component such as battery, circuit board in the earlap 2, specifically also can select to set up according to actual demand.

In the present embodiment, in order to further improve the wearing experience of the consumer, the sponge body 6 is fixedly mounted on the outer side surface of the ear cover 22.

In order to facilitate the storage of the earphones, in order to enable the earmuffs 2 to be folded inside the headband 1, the end part of the headband 1 is fixedly provided with the hinge seat 3, the hinge seat 3 is provided with a hinge hole 31, and one end of the hinge column 4 is provided with a hinge part 41 inserted into the hinge hole 31. It should be noted that, in order to improve the fluency of storage, the hinge hole 31 and the hinge post 4 are both provided in a T shape, so that the hinge post 4 can rotate around the axial direction of the hinge portion 41, thereby achieving the purpose of storing the earmuff 2.

As the improvement, the other end of the hinge column 4 is inserted into the ear shell 2, the ear shell 2 can rotate (rotate) around the axial direction of the hinge column 4, only a through hole needs to be formed in the side surface of the ear shell 2, the hinge column 4 is inserted into the through hole, and some damping mechanisms can be arranged between the through hole and the hinge column 4 to limit or increase friction, but the ear shell 2 cannot be influenced to rotate or move in a telescopic mode (stretching motion) along the axial direction of the hinge column 4.

In order to limit the rotation range of the hinge post 4 when the earshell 2 is pulled out and the earshell 2 is limited, a limiting sleeve 5 covering the hinge post 4 is fixedly mounted in the earshell 2, a limiting opening 51 is formed in the peripheral side surface of the limiting sleeve 5, the hinge post 4 is provided with a limiting part 42 protruding out of the outer side surface of the hinge post 4, and in this embodiment, the limiting part 42 is a limiting screw fixedly connected to the hinge post 4 for convenience of manufacture.
