Loudspeaker module group

The utility model, which relates to the technical field of the electroacoustic product, discloses a loudspeaker module group comprisijng a housing. A single loudspeaker body is accommodated into the housing and divides the inner cavity of the overall module group into a front sound cavity and a rear sound cavity; and sound-absorbing particles are arranged in the rear sound cavity. Besides, a meshy isolation component for separating the sound-absorbing particles from the single loudspeaker body is also arranged in the rear sound cavity and separate the overall rear sound cavity into a filling zone and a non-filling zone, wherein the sound-absorbing particles are arranged in the filling zone. The sound-absorbing particles are made of non-foaming materials; and the external diameter of each sound-absorbing particle is larger than or equal to 0.01mm and is less than the height of the filling zone. According to the loudspeaker module group, the rear cavity can be filled by the sound-absorbing particles to the greatest extent and the sound absorption performances of the filled sound-absorbing particles can be fully utilized, so that the acoustical performance of the product is good. Moreover, the production efficiency is high and the production cost is low.
