Abstract: Provided is a speaker box and a mobile terminal. The speaker box is applied to the mobile terminal and includes a shell having a receiving space and a speaker unit received in the receiving space. The shell includes a bottom shell and a metal top plate covering the bottom shell and together defining the receiving space. The metal top plate includes a main body covering one end of the sidewall away from the bottom wall and a connector extending outwards from the main body. A positioning portion is provided in the connector. The housing extends toward the connector to form a heat stake supporting and fixing the connector. The connector is fixed to the housing after hot melting of the heat stake. A stable connection between the speaker box and the mobile terminal can be achieved and mounting is fast and firm.

Abstract: The present disclosure discloses electronic terminal including housing, sound producing device and switching structure, and first sound cavity channel and second sound cavity channel formed in the housing. The sound producing device defines sound producing cavity jointly with housing. The electronic terminal further includes mounting groove formed in housing. The switching structure includes baffle slidably arranged in mounting groove and driving portion driving baffle to slide in mounting groove. The driving portion drives baffle to slide into first sound cavity channel or the second sound cavity channel, to close first sound cavity channel or the second sound cavity channel. The baffle can be driven to slide in mounting groove to selectively close first sound cavity channel or second sound cavity channel, to prevent the problem that the terminal, when using one of the first sound cavity channel and the second sound cavity channel, is affected by the other.
