Disclosed in the present application is a sound generating device module, comprising: a housing having a cavity therein; a frame fixedly provided in the cavity, a high-pitch sound generating unit and a low-pitch sound generating unit are respectively provided on two opposite sides of the frame, the high-pitch sound generating unit and the low-pitch sound generating unit share the cavity; a baffle plate is provided on a side of the housing corresponding to the high-pitch sound generating unit, and the baffle plate and the housing together form a side sound output port corresponding to the high-pitch sound generating unit; and the sound generating device module is configured to form a front sound output structure for the low-pitch sound generating unit.

Sound generating device module

The present disclosure provides a loudspeaker module and an electronic device. The loudspeaker module comprises a module housing and a loudspeaker unit, wherein the module housing has a cavity and the loudspeaker unit is accommodated in the cavity, the loudspeaker unit divides the cavity into a front acoustic cavity and a rear acoustic cavity; wherein a sound outlet hole is provided on the module housing, the front acoustic cavity is communicated with the sound outlet hole by a sound outlet channel; wherein a concave-convex structure is provided separately in a region of the module housing corresponding to the sound outlet channel. According to the present disclosure, resonance of the module housing can be effectively suppressed, to achieve the effects of increasing high-frequency sensitivity of the loudspeaker module and reducing distortion.
