Abstract
A speaker module relates to the technical field of electroacoustic products, and comprises a lower module casing, an upper module casing and a steel sheet which are successively combined together. A speaker monomer is contained in a space enclosed by the lower module casing, the upper module casing and the steel sheet. The speaker monomer, the upper module casing and the steel sheet together enclose a front sound cavity of the module. The front sound cavity is in communication with a sound outlet hole of the module, and the sound outlet hole is located on a side part of the speaker monomer. A sheet is adhered inside the steel sheet, the thickness of the sheet being about 0.1 mm˜0.2 mm and the material of the sheet being a soundproof material.
