Abstract: Disclosed is a loudspeaker module, which comprises a loudspeaker unit and a module housing for accommodating the loudspeaker unit. The loudspeaker unit comprises a magnetic circuit assembly and a vibration assembly. The module housing comprises a polycarbonate plastic material layer and an elastomeric material layer having a compression amount. The polycarbonate plastic material layer forms an inner layer of the module housing. The elastomeric material layer is at least partially bonded on the outside of the polycarbonate plastic material layer to form the outer layer of the module housing. The polycarbonate plastic material layer and the elastomeric material layer are formed by double-shot injection molding. The loudspeaker module of the present disclosure can effectively solve the problem of the damage to the module housing caused by inflexible contact with other components of the whole machine, and can utilize the outer layer structure to change the resonance frequency, thereby effectively ameliorating the resonance phenomenon of the module housing and optimizing the product performance.
