Abstract

The present disclosure provides an earphone comprising a sound production component and an ear hook. In a wearing state, the ear hook is configured to place the sound production component at a position near an ear canal but not blocking the ear canal. An inner contour of the ear hook's projection on a user's sagittal plane includes a first curve having an extremum point in a first direction. The first direction is perpendicular to a long-axis direction of a projection of the sound production component on the sagittal plane. The extremum point is located behind a projection point of an upper vertex of the ear hook on the sagittal plane, and the upper vertex is a highest point of an inner contour of the ear hook along the user's vertical axis. An inclination angle of the long-axis direction relative to a horizontal direction is within a range of 13°-21°.
