1. An earphone, comprising:
a sound production component including a transducer and a housing accommodating the transducer; and
an ear hook including a first portion and a second portion connected in sequence, wherein in a wearing state, the first portion is hung between an auricle and a head of a user, and the second portion extends towards a side of the auricle away from the head and connects with 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;
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 a highest point of an inner contour of the ear hook along a vertical-axis of the user in the wearing state; and
the housing and the first portion of the ear hook clamp the auricle of the user and provide a clamping force of 0.03 N-1 N to the auricle of the user.
