Abstract
The present disclosure relates to an open earphone. The open earphone may include a sound production device and an ear hook including a first part and a second part connected in sequence. The first part may be hooked and arranged between an auricle and a head of a user. The second part may extend to a front lateral surface of the auricle and may be connected to the sound production device. The sound production device may be worn at a position that is near an ear canal without blocking an earhole of the user. The sound production device may be at least partially inserted into an auricular concha cavity of the user. An overlap ratio of a projection area of the sound production device on a sagittal plane to a projection area of the auricular concha cavity on the sagittal plane may be not less than 44.01%.
