EARPHONES AND MOBILE TERMINAL

This application provides an earphone and a mobile terminal. The earphone includes a housing and a speaker assembly. The housing internally includes a front cavity and a rear cavity that are separated by the speaker assembly. The front cavity is located on a side that is of the speaker assembly and that is a sound output direction, and the rear cavity is located on an opposite side of the sound output direction of the speaker assembly. One or more sound guide channels are disposed in the housing, each sound guide channel is disposed in a sidewall of the housing, and each sound guide channel is configured to: when the earphone is normally worn, connect air inside an ear canal of a user to air outside the ear canal without connecting air in the front cavity to air in the rear cavity. When the foregoing solutions are used, an environment inside the ear canal is connected to an environment outside the ear canal by using the sound guide channel disposed in the housing, so that sound pressure inside the ear canal can be exposed or exhausted to a surrounding environment outside the earphone. This reduces pressure inside the ear canal, thereby improvising sound experience of the user.
