AI Technical Summary

Technical Problem

Existing ear clip-on open-back wireless headphones use a soft gel-wrapped memory steel wire structure, which makes it difficult to precisely maintain and adjust the clamping force. This results in a dilemma between comfort and stability for users with different ear shapes, and the manufacturing process is complex and costly.

Method used

It employs a torsion spring with a compressed state inside the rotating shaft. The clamping force is precisely controlled by adjusting the degree of compression of the torsion spring. Combined with the rotating groove and pin structure, the clamping force between the speaker housing and the functional housing can be adjusted to adapt to the wearing needs of different ear shapes.

Benefits of technology

It achieves precise maintenance and adjustment of clamping force, taking into account the comfort and stability needs of users with different ear shapes, and reduces manufacturing difficulty and cost.

Abstract

The utility model discloses an ear -clip formula earphone with rebound function. The earphone includes function storehouse casing, arc connecting piece and rotating component, rotating component includes pivot and torsional spring, one end of arc connecting piece connects pivot, and the other end fixedly connects function storehouse casing, torsional spring is contained in pivot, and, torsional spring is compressed first preset angle under the restriction of pivot. The ear -clip formula earphone with rebound function sets up the torsional spring in the pivot in the compressed state, and the torsional spring is used for providing the clamping force between the loudspeaker storehouse casing and function storehouse casing, and the accurate control of clamping force can be realized through the compression degree of torsional spring, the stress of concha cavity and ear back is adjusted to a accurate range, the existing ear -clip formula earphone cannot reach the accurate maintenance and adjustment of the clamping force difficult problem is solved, and the comfort and stability demand of different ear type users can be considered.
