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.

Abstract: A loudspeaker module comprises a housing and a loudspeaker unit. A cavity for accommodating and fixing the loudspeaker unit is provided in the housing. The loudspeaker unit divides the cavity into a front and rear sound cavity. A sound hole is provided on the housing, which is connected to the front sound cavity by a sound channel, and the loudspeaker unit has a square structure. The sound channel comprises an inner end close to the loudspeaker unit and an outer end communicated with the sound hole. The width of the inner end is longer than three fifths of the length of a side, corresponding to the inner end, of the loudspeaker unit. The loudspeaker module of the present invention has the advantage of good acoustic performance.

Abstract: A speaker sounding hole device includes a speaker single-unit front cover and a module housing. The speaker single-unit front cover is rectangular, the long edges and/or short edges of the speaker single-unit front cover are provided with open grooves, and the speaker single-unit front cover and the module housing are correspondingly assembled by means of the open grooves. The speaker single-unit front cover provided with the open grooves and the module housing form a front cavity of the speaker sounding hole device. Spaces formed by the open grooves are connected with the front cavity of the speaker sounding hole device to form a sounding channel of the speaker sounding hole device. The device can solve the problems of high cost, long tuning time of the product performance, poor sounding effects and low product efficiency.
