Description
Technical Field
[0001] The utility model relates to the technical field of Bluetooth earphones, in particular to an ear hook rotating structure of a Bluetooth earphone. Background Art
[0002] An ear-hook Bluetooth headset is not difficult to understand literally. It is a headset that hangs on the ear through a curved bracket. Compared with most headsets, it has the best stability due to the ear-hook wearing method, and it is not easy to fall off even in more intense sports scenes. In the existing ear-hook Bluetooth headsets, most of the ear-hook parts have a fixed size and space, which makes them unable to adapt to users with different sizes of auricles. A small number of ear-hook parts are rotatable, but the structure is relatively simple. Due to the lack of a positioning structure, the ear-hook is easy to slide automatically when rotating, causing the size of the ear-hook part to not match the user's auricle, affecting the wearer's experience.
