Abstract: A loudspeaker module emitting sound at a lateral side comprises a loudspeaker unit and a module housing comprising a lower module housing, a middle module housing and an upper module housing. A space formed by the loudspeaker unit, the middle module housing and the lower module housing is a rear sound cavity. A space formed by the loudspeaker unit, the middle module housing and the upper module housing is a front sound cavity. The loudspeaker module further comprises a cover plate which forms a cavity together with the upper module housing. The cavity is communicated with the rear sound cavity through a conducting hole. By utilizing the loudspeaker module of the present invention, superfluous space of the upper module housing can be converted into the rear sound cavity, and therefore the size of the rear sound cavity is increased, and the acoustic performance of the loudspeaker module is improved.

Abstract: The present invention discloses a speaker module and a sound production device. The module comprises a module shell and a speaker unit mounted in the module shell. The module shell comprises a shell main body and two fixed pole plates connected fixedly on the shell main body. The two fixed pole plates are insulated from each other, and each of the two fixed pole plates has a connecting portion exposed to the outside of the shell main body. A vibration system of the speaker unit is provided with a movable pole plate, and each of the two fixed pole plates together with the movable pole plate form a variable capacitor. The speaker module is configured to output an electrical signal representing a vibration displacement of the vibration system by the connecting portions of the two fixed pole plates.
