Earphone with elastic function
By using a compression torsion spring and rotating groove structure within the hinge in the ear clip-on headphones, the problem of the inability to precisely maintain and adjust the clamping force of existing ear clip-on headphones has been solved, achieving a balance between comfort and stability in the ear clip-on headphones, while reducing manufacturing difficulty and cost.

AI Technical Summary
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.
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.
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.
