Provided in an embodiment of the present disclosure is a speaker module and an electronic device. The speaker comprises: a module housing, a speaker unit and sound-absorbing particles; wherein the speaker unit divides an inner cavity enclosed by the module housing into a front acoustic cavity and a rear acoustic cavity; the rear acoustic cavity is provided with a filling area separated out by a partition wall, and the filling area is provided with a port enabling air circulation; the sound-absorbing particles are filled in the filling area and are confined within the filling area; a gap is formed between the port of the filling area and an inner wall of the module housing, and sound-absorbing cotton is provided in the gap. The technical solution of the present disclosure can reduce influence of the resonance caused by the gap on acoustic performance of the speaker module.
