The first curve has an extremum point in a first direction 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 sagittal plane.

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.
