Abstract
The present disclosure relates to an earphone including 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 a projection of the ear hook on the user's sagittal plane includes a first curve that has 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. The extremum point is located behind a projection point of an upper vertex of the ear hook on the user's sagittal plane, and the upper vertex of the ear hook is the highest point of an inner contour of the ear hook along a vertical axis of the user.
