Claim 0:
1. An earphone comprising:
a sound production component including a transducer and a housing for accommodating the transducer; and
an ear hook, wherein in a wearing state, a first portion of the ear hook is hung between an auricle and a head of a user, a second portion of the ear hook connects with the first portion of the ear hook, the second portion of the ear hook extends towards a side of the auricle away from the head and connects to the sound production component to place the sound production component at a position near an ear canal but not blocking an ear canal opening, wherein
an inner contour of a projection of the ear hook on a user's sagittal plane includes a first curve, the first curve has an extremum point in a first direction, and the first direction is perpendicular to a long-axis direction of a projection of the sound production component on the user's sagittal plane;
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 is a highest point of an inner contour of the ear hook along a vertical axis of the user in the wearing state; and
an inclination angle of the long-axis direction of the projection of the sound production component on the user's sagittal plane relative to a horizontal direction is within a range of 13°-21°.
