Earphone

Abstract

The invention mainly relates to an earphone which comprises a sound production part, an abutting part and an ear hook, the ear hook comprises an elastic metal piece, the elastic metal piece comprises an elastic section in a reference section arranged in the length direction of the ear hook and in a natural state, and the elastic section is divided into a first elastic section and a second elastic section which are arranged in an arc shape and connected with each other; the curvature radius of at least part of the section, with the connecting point as the starting point, of the first elastic section and the curvature radius of at least part of the section, with the connecting point as the starting point, of the second elastic section are gradually increased, the length of the first elastic section is larger than that of the second elastic section, and at the first end point, away from the connecting point, of the first elastic section, the curvature radius of the second elastic section is larger than that of the second elastic section. The first bullet segment has a first radius of curvature at a first end point of the first bullet segment away from the connection point, and the second bullet segment has a second radius of curvature at a second end point of the second bullet segment away from the connection point, the first radius of curvature being greater than the second radius of curvature. Through the above mode, the wearing stability of the earphone can be effectively improved.
