(54) MOBILE TERMINAL THAT PREVENTS SOUND LEAKAGE AND SOUND OUTPUT METHOD FOR MOBILE TERMINAL


(57) This application provides a mobile terminal for preventing sound leakage and a sound output method for a mobile terminal. A screen sound production component is disposed on a back side of a screen. Therefore, when a user has a high requirement for a sound receiving effect, a high requirement for confidentiality of sound content, or a high requirement for sound quality, the mobile terminal mainly depends on the screen sound production component to drive the screen to vibrate, so as to produce sound, that is, the mobile terminal uses a privacy mode. In the privacy mode, a location at which the screen produces sound is close to the ear of the user. Therefore, it can be ensured that the user directly receives a large amount of sound produced by the screen, instead of mainly receiving sound by using a sound output hole on the mobile terminal. In this way, the following case can be avoided: When imposing a requirement on sound, the user can receive sound only by using a conventional earpiece mode on the mobile terminal. Therefore, the following problem can also be avoided: A large amount of sound produced by a first speaker component in the earpiece mode is leaked when the sound is output from the sound output hole.
