Abstract
An earphone including a housing, a first speaker and an audio outlet is provided. The housing includes an insertion end and a main body. The insertion end is into the entrance of a user's ear when worn by the user, and the main body extends from the insertion end and defines an auricle contact surface and an external connecting surface opposite to the auricle contact surface. The auricle contact surface faces the user's auricle and the external connecting surface communicates to the external environment when the earphone is worn. The first speaker is contained within the main body to divide into a front chamber and a first rear chamber. A part of the first rear chamber is adjacent to the auricle contact surface. A sound output surface of the first speaker faces the external connecting surface. The audio outlet is formed in the insertion end to let out the sound.
