Abstract
An earphone which includes a sound production component and an ear hook may be provided. The sound production component includes a transducer and a housing accommodating the transducer. A first portion of the ear hook is hung between an auricle and the head of a user, and a second portion extends toward a side of the auricle away from the head and is connected to the sound production component. In a non-wearing state, the ear hook and the sound production component form a first projection on a first plane; in a wearing state, the ear hook and the sound production component form a second projection on a sagittal plane of a human body. Each of the first projection and the second projection includes an outer contour, a first end contour, an inner contour, and a second end contour.
