Abstract

The adjustable headphone shell structure comprises earmuffs and a support used for being connected with the earmuffs, the support is elastic, a soft strip is fixedly connected to the bottom of the support, a positioning box is arranged at the bottom of each earmuff, openings are formed in the left side and the right side of the bottom of each positioning box, and an adjusting belt is arranged at the bottom of each positioning box. The left end and the right end of the adjusting band sequentially penetrate through the opening and the positioning box and are connected with the earmuffs through fixing and connecting devices. The effect of adjusting the extrusion force of the earmuff is achieved by utilizing the winding distance of the adjusting belt, the pulled adjusting belt can be accurately positioned by arranging a pressing plate and teeth, the situation that normal use of a user is affected due to sliding displacement of the fixed adjusting belt is avoided, and the practicability of the earmuff is improved. The problems that an existing earphone with extrusion force does not have the effect of adjusting the extrusion force, part of ears of a user can feel painful after being extruded for a long time, and the comfort of wearing the earphone is seriously affected are solved.

Description

technical field [0001] The invention relates to the technical field of headphones, in particular to an adjustable headphone shell structure. Background technique [0002] The earphone is a device to prevent the volume of the device from spreading. During use, it is necessary to use a hanger with inward elastic force to connect the two earphones. However, the existing earphones with extrusion force do not have the ability to adjust the extrusion force. As a result, some users' ears will experience pain after being squeezed for a long time, which seriously affects the comfort of wearing headphones. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technology, the object of the present invention is to provide an adjustable earphone shell structure, which has the advantage of adjustable earphone extrusion force, and solves the problem that the existing earphones with extrusion force do not have the right Due to the effe...
