Abstract:
Disclosed is a speaker module. The speaker module comprises: a module housing, the module housing being provided with a cavity; and a speaker component, the speaker component being disposed in the cavity and dividing the cavity into a front cavity and a rear cavity. The portion of the module housing corresponding to the rear cavity is a rear cavity housing portion, and the rear cavity housing portion is provided with a protruding portion protruding from the surface of the rear cavity housing portion. Under the premise that the volume of the rear cavity is not substantially reduced, the technology of the utility model suppresses the resonance of the rear cavity housing portion, thereby reducing the noise, reducing the distortion, and improving the acoustic performance.
