Description

Technical Field

[0001] This utility model relates to the field of headphone technology, and in particular to a headphone arm mounting structure and a headphone. Background Technology

[0002] Currently, some headphones on the market use a method where the arm is installed by first fixing the arm cover to the ear shell with screws, thus limiting the arm's travel. This restricts the arm's rotational movement to a certain angle between the arm cover and the ear shell. A spring inserted into the ear shell provides elasticity for the arm's rotational movement within its travel range. Finally, a pin prevents the arm from being pulled out, thus limiting its axial movement and restricting its rotational movement to around an axis within the arm frame. This structure requires more parts, resulting in higher manufacturing and assembly costs for headphones and impacting assembly efficiency.

[0003] For example, Chinese patent application number CN202323496423.0 discloses an elastic face-fitting structure for headphones and headphones. Specifically, it discloses that "the first mounting base has a mounting groove and a shaft opening; the spring is disposed in the mounting groove; the rotating shaft of the second mounting base is rotatably disposed in the shaft opening; a limiting member is disposed in the first mounting base and restricts the second mounting base to the first mounting base. The connecting rod has a limiting groove; the connecting rod is rotatably inserted into the second mounting base; a limiting pin passes through the second mounting base and the limiting groove. Rotating shafts are provided on both sides of the second mounting base, and the rotating shafts can rotate in the shaft opening. During assembly, the second mounting base is placed on the first mounting base, the rotating shaft is embedded in the shaft opening, and then the limiting member is fixed to the first mounting base, restricting the second mounting base to ensure that the second mounting base can swing." To complete the assembly of the connecting rod, the limiting member (support arm cover), the second mounting member, the first mounting base, the spring, etc., are required. This structure requires many parts, and the manufacturing and assembly costs incurred during production affect assembly efficiency. Utility Model Content
