The invention discloses a loudspeaker module, and relates to the technical field of electric-acoustic products. The loudspeaker module comprises a module shell, wherein a single loudspeaker body is accommodated in the module shell; a sound making hole of the module is positioned in a side portion of the single loudspeaker body; the inner cavity of the whole module is divided into a front sound cavity and a rear sound cavity by the single loudspeaker body; the front sound cavity is communicated with the sound making hole; and sound-absorbing cotton is arranged in the front sound cavity, is fixed on the module shell and is far away from vibration space of a vibration membrane of the single loudspeaker body. By the loudspeaker module, the expression of a sensitivity curve of the module on high frequency is effectively improved under the condition that the structure of the front sound cavity is not required to be changed, the acoustic performance of the module is improved, and the structure of the front sound cavity of the module is also simplified.
