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.

Abstract: An acoustic device comprises a sound generating unit comprising a diaphragm. An acoustic wave at a front side radiates outwards through a sound outlet. A closed cavity is formed at a rear side of the vibrating diaphragm. Volume adjustment regions are provided in the closed cavity, the volume adjustment regions are a sound absorption portion, a porous sound absorbing material is provided on the sound absorption portion, and the volume adjustment regions are a flexibly deformable portion. The closed cavity is divided into first and second closed cavities by a partition. The first closed cavity is adjacent to the diaphragm, the second closed cavity is far away from the vibrating diaphragm. The flexibly deformable portion is at least part of the partition, and deforms flexibly. The sound absorbing material is provided in the first and/or the second closed cavity, and effectively increase the equivalent volume of the closed cavity.

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.
