Abstract
An earphone includes a housing provided with an accommodating groove and an opening groove. The opening groove connects the accommodating groove and the outside of the housing. A first hole is formed in the groove bottom of the accommodating groove. The earphone further includes an ear hanger, wherein one end of the ear hanger is provided with a rotating part inserted into the accommodating groove through the opening groove. The rotating part is provided with a second hole, a rotating shaft passes through the second hole and inserted into the first hole. The housing and the rotating part are rotatably connected around the rotating shaft. The earphone can effectively solve the problem that the rotating shaft of an existing ear-hanging earphone is prone to radial deflection, and is beneficial to enhancing the use hand feeling of a user.
