Box body, earphone box and earphone package

Abstract

A box body, an earphone box and an earphone package are disclosed. According to the box body, a first magnetic piece is arranged on the outer side of a first guide piece of a first shell, a second magnetic piece is fixedly connected with a second guide piece of a second shell, and when the first shell and the second shell rotate in a hinged mode, and when the first guide piece drives the first magnetic piece to slide above or below the second magnetic piece , the first magnetic and the second magnetic repel each other to enable the first shell and the second shell to tend to be in an open state or a closed state, and the box body can be automatically opened and closed according to the principle that like poles of the magnetic pieces repel each other, and the box body still has retention force in the open state and the closed state, so that the box body does not shake randomly.

Description

technical field [0001] The invention relates to the technical field of portable wireless devices, in particular to a box body, an earphone box and an earphone set. Background technique [0002] In the past wired earphones, the left and right earphones need to be connected by wire to form the left and right channels to produce a stereo effect, but the inconvenience caused by the shackles of the wires limits the wearing scenarios. With the emergence of wireless earphones, the sense of freedom of wireless wearing has improved the comfort and convenience of earphones. Wireless earphones need to be equipped with a corresponding earphone box for charging and storage. [0003] At present, the opening and closing methods of wireless earphone boxes mainly include a shaft structure without springs and a shaft structure with bidirectional springs added. Due to the limited space in the earphone box, the unspring-loaded shaft structure of the earphone box needs to cooperate with magnet...

AI Technical Summary

Problems solved by technology

Due to the limited space in the earphone box, the unspring-loaded shaft structure of the earphone box needs to cooperate with magnets to realize the opening and closing of the earphone box. This solution can realize the closing function, but it cannot automatically open the upper cover of the earphone box; in the open state, the earphone The upper cover of the box has no binding force, it will shake at any angle, and the wrong operation of automatic closing often occurs

Partially use two-way springs to realize the opening and closing of the earphone box, which can automatically open the upper cover of the earphone box, but there will be noise problems caused by spring friction, and the spring force is greatly affected by the position tolerance, which is likely to cause poor elasticity
