AI Technical Summary
After wearing the existing ear clip earphones, the position and angle of the in-ear unit are difficult to adjust, which makes it difficult to fit the sound out direction to the right ear canal, resulting in the problem of more sound leakage.
By introducing a rotating member, including a rotating shaft, a rotating ball and a limiting block, the angle of the inlet unit is allowed to be adjusted. The rotating ball interferes with the inner wall of the rotating cavity to ensure sufficient friction during rotation, and the limiting block defines the maximum rotation angle of the rotating element.
The angle adjustment of the in-ear unit is realized, so that the sound output direction can be directed to the ear canal, reduce sound leakage, and allows the user to adjust the in-ear unit to the most comfortable wearing position, while avoiding the problem of damage to the headphones due to excessive rotation angle.
