The present invention relates to the technical field of electro-acoustic products. 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 part, a plurality of cavity expansion portions formed by incomplete filling is distributed on the supporting part at intervals, and all the cavity expansion portions are separately communicated with the rear voice cavity. The loudspeaker module of the present invention solves the technical problem of F0 rising due to a narrow rear voice cavity of a loudspeaker module in the prior art. The loudspeaker module of the present invention is larger in size of a rear voice cavity, low in F0, wide in frequency band, good in acoustic performance and long in service life; and meanwhile, the assembling process difficulty is low, and the production efficiency is high. |
