摘要： Disclosed is a loudspeaker module, comprising a shell, wherein a vibrating system and a magnetic circuit system are accommodated in the shell, the vibrating system comprises a vibrating diaphragm and a voice coil which are combined together; a whole inner cavity of the module is divided by the vibrating diaphragm into two cavities, i.e. a front voice cavity and a rear voice cavity; an edge portion of the vibrating diaphragm is fixed on the shell by using an annular supporting member, a plurality of cavity expansion portions formed by incomplete filling are distributed on the supporting member at intervals, and each of the cavity expansion portions is communicated with the rear voice cavity. The loudspeaker module of the present disclosure solves the technical problem of F0 rising due to the narrow rear voice cavity of the loudspeaker module in the prior art.
