Abstract:
The embodiment of the present invention provides a loudspeaker module and electronic equipment. The loudspeaker module comprises a housing and a loudspeaker unit; a closed rear acoustic cavity is formed between the loudspeaker unit and the housing; a first porous sound absorbing material and a second porous sound absorbing material are disposed in a resonance area of the rear acoustic cavity; the first sound absorbing material partitions the rear acoustic cavity into a first rear cavity close to the loudspeaker unit and a second rear cavity away from the loudspeaker unit, and air currents in the rear acoustic cavity flow to the second rear cavity from the first rear cavity; and the second sound absorbing material located in the second rear cavity is disposed in a direction of the air currents and is disposed close to the first sound absorbing material. According to the technical solution provided in the embodiment of the present invention, the degree of influence on F0 and Q value is reduced while standing waves are eliminated, such that excellent acoustic performance can be achieved.
