    CPC classification number: H04R1/1016

    Abstract: The present disclosure relates to acoustic technology, in particular to an earphone including a sound generation portion. The sound generation portion includes a transducer and a housing for accommodating the transducer. The earphone further includes an earhook. The earhook includes a first portion and a second portion. The first portion may be hung between an auricle and the head of a user, and the second portion may be connected to the first portion, extends toward an anterolateral side of the auricle, and may be connected to the sound generation portion. The sound generation portion may be fixed near an ear canal without blocking an opening of the ear canal. In at least one frequency range, when an input current of the transducer does not exceed 35.3 mA, a maximum sound pressure that the sound generation portion is able to provide to the ear canal may not be smaller than 75 dB.
