Abstract: A loudspeaker module emitting sound at a lateral side comprises a loudspeaker unit and a module housing comprising a lower module housing, a middle module housing and an upper module housing. A space formed by the loudspeaker unit, the middle module housing and the lower module housing is a rear sound cavity. A space formed by the loudspeaker unit, the middle module housing and the upper module housing is a front sound cavity. The loudspeaker module further comprises a cover plate which forms a cavity together with the upper module housing. The cavity is communicated with the rear sound cavity through a conducting hole. By utilizing the loudspeaker module of the present invention, superfluous space of the upper module housing can be converted into the rear sound cavity, and therefore the size of the rear sound cavity is increased, and the acoustic performance of the loudspeaker module is improved.

Abstract translation: 在侧面发射声音的扬声器模块包括扬声器单元和包括下模块壳体，中间模块壳体和上模块壳体的模块壳体。 由扬声器单元，中间模块壳体和下模块壳体形成的空间是后音腔。 由扬声器单元，中间模块壳体和上模块壳体形成的空间是前声腔。 扬声器模块还包括与上模块壳体一起形成空腔的盖板。 空腔通过导孔与后声腔连通。 通过利用本发明的扬声器模块，可以将上模块壳体的多余空间转换成后声腔，从而提高后音腔的尺寸，提高扬声器模块的声学性能。
