WIPO Patent Application WO/2021/098528
Kind Code:
A1
Abstract:
The present invention provides a loudspeaker and an electronic device. The loudspeaker module comprises a module housing having a cavity and a loudspeaker unit received in the cavity; the loudspeaker unit divides the cavity into a front acoustic cavity and a rear acoustic cavity; the module housing is provided with a sound outlet hole; the front acoustic cavity is communicated with the sound outlet hole by means of a sound outlet channel; concave/convex structures are provided at intervals in a region of the module housing corresponding to the sound outlet channel. By using the invention, 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.
