Abstract: Disclosed is a loudspeaker module applied inside a terminal, wherein, the terminal comprises a terminal housing, and the loudspeaker module is fixed inside the terminal. The loudspeaker module comprises a loudspeaker unit and a module housing for accommodating and fixing the loudspeaker unit. A closed space formed by the loudspeaker unit, an outer wall of the module housing, and the terminal housing is a rear sound cavity. By means of the loudspeaker module provided in the present invention, the usable space inside the terminal can be converted into the rear sound cavity, so that the space of the rear sound cavity is enlarged, and the acoustic performance of the loudspeaker module can be effectively improved. Therefore, the present invention makes full use of the inside space of the terminal to realize the thinning of the loudspeaker module without changing the inside space of the terminal, and achieves good acoustic performance.
