Loudspeaker module and electronic apparatus
A loudspeaker module and an electronic apparatus are disclosed, the loudspeaker module comprises a housing, a loudspeaker unit and a barrier rib body; the loudspeaker unit is provided in an inner cavity of the housing and divides the inner cavity of the housing into a front acoustic cavity and a rear acoustic cavity, the rear acoustic cavity is filled with sound-absorbing particles, and a cavity wall of the rear acoustic cavity is provided with a leakage hole. The barrier rib body is provided in the rear acoustic cavity, at least a part of the barrier rib body faces the leakage hole, and the distance between the leakage hole and the part of the barrier rib body facing the leakage hole is less than the size of the sound-absorbing particles. The technical solution can reduce the occurrence of the situation where the sound-absorbing particles block the leakage hole.
