A loudspeaker module, comprising a housing, wherein a single loudspeaker body (50) is accommodated into the housing and divides the inner cavity of the overall module into a front acoustic cavity and a rear acoustic cavity; the rear acoustic cavity is filled with sound absorbing particles (60); netlike isolating components (80a, 80b) for isolating the sound absorbing particles (60) from the single loudspeaker body (50) are also arranged in the rear acoustic cavity, and separate the overall rear acoustic cavity into a filling zone and a non-filling zone; the sound absorbing particles (60) are located in the filling zone; the sound absorbing particles (60) are made of a non-foaming material, and have the external diameters that are more than or equal to 0.01mm and are smaller than the height of the filling zone. According to the loudspeaker module, the rear cavity can be filled with the sound absorbing particles (60) to the greatest extent, and the sound absorbing performance of the filled sound absorbing particles (60) can be fully utilized, so that the loudspeaker module has the advantages of good acoustic performance, high production efficiency and low production cost. |
