Abstract

The invention provides a loudspeaker module and an electronic device. The loudspeaker module comprises a module shell with a cavity and a loudspeaker monomer accommodated in the cavity, and the loudspeaker monomer divides the cavity into a front vocal cavity and a rear vocal cavity. A sound outlet hole is formed in the module shell, and the front sound cavity is communicated with the sound outlethole through a sound outlet channel. Concave-convex structures which are distributed at intervals are arranged in the area, corresponding to the sound outlet channel, of the module shell. By utilizingthe loudspeaker module, resonance of the module shell can be effectively suppressed, and the effects of improving the high-frequency sensitivity of the loudspeaker module and reducing distortion areachieved.

Description

technical field [0001] The invention relates to the technical field of electronic products, and more specifically, to a module casing and a loudspeaker module equipped with the module casing. Background technique [0002] With the development trend of light and thin electronic products, the requirements for the thickness of speaker modules are getting higher and higher. Due to the height restriction of the speaker module, the wall thickness of the module casing is usually reduced to increase the internal space, which requires injection molding of steel sheet inserts on the module casing to enhance the strength of the module casing. The currently used steel sheet insert injection molding process includes: after bending the circumference of the steel sheet, inserting it into the plastic when injecting the loudspeaker module casing, thereby forming the module casing. [0003] However, when the current module shell is assembled, it is easy to cause the center of the upper shell...
