Abstract: An earphone and a mobile terminal is provided, in which 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.

Abstract: This application discloses a sound masking method and apparatus, and a terminal device. When the terminal device uses a receiver as an output end of an audio signal, the terminal device determines, based on the audio signal, a masking sound signal, and then transmits the masking sound signal by using a speaker. The masking sound signal is determined based on the audio signal, and a difference between a distance from the speaker to a far field and a distance from the receiver to the far field is small. Therefore, the masking sound signal can better mask a leaked sound of the receiver and prevent information leakage in a call sound.
