The loudspeaker module comprises an elastic piece, a vibrating diaphragm assembly, a driving assembly and a basin stand, the elastic piece further comprises an outer fixing part, a central elastic piece located on the inner side of the outer fixing part and a connecting arm connected with the outer fixing part and the central elastic piece, the outer fixing part is connected with the basin stand, the central elastic piece is connected with the driving assembly, and the central elastic piece is connected with the driving assembly. The central elastic piece is further connected with a transmission part, the vibrating diaphragm assembly is connected with the transmission part, the driving assembly is controlled to drive the central elastic piece and the connecting arm to vibrate, the vibrating diaphragm assembly is driven by the transmission part to synchronously vibrate and produce sound, the connecting arm is further connected with a balance weight, and the compliance of the connecting arm and/or the weight of the balance weight are/is used for adjusting the output characteristic of vibration sound production. According to the loudspeaker module provided by the invention, the output characteristic is adjusted through the elastic sheet and the counterweight, the loudspeaker module is easy to implement in a thin space, and the low-frequency response performance is improved while the medium-high frequency playback quality is ensured, so that the full-band sound playback quality of the loudspeaker is improved.
