The present application relates to the technical field of acoustics, and in particular to an earphone, comprising: a sound production part comprising a transducer and a housing accommodating the transducer, the sound production part at least partially extending into an auricular concha cavity; and an earhook comprising a first portion and a second portion, wherein the first portion is hung between the auricle and the head of a user, and the second portion is connected to the first portion, extends towards the front outer side surface of the auricle and is connected to the sound production part so as to fix the sound production part near the ear canal but not block the opening of the ear canal. The sound production part and the auricle respectively have a first projection and a second projection on a sagittal plane, the centroid of the first projection and the highest point of the second projection have a first distance in a vertical axis direction, and the ratio of the first distance to the height of the second projection in the vertical axis direction is between 0.35 and 0.6; in at least part of a frequency range, when the input voltage of the transducer does not exceed 0.6 V, the maximum sound pressure that the sound production part can provide into the ear canal is not less than 75 dB.
