Disclosed is a speaker module, comprising a module housing and a speaker unit accommodated in the module housing. The speaker unit partitions a module cavity encircled by the module housing into two cavities, namely a front acoustic cavity and a rear acoustic cavity. A separator component is provided within the rear acoustic cavity. The separator component partitions the rear acoustic cavity into an accommodating cavity and a sound-absorbing cavity. The sound-absorbing cavity is filled with sound-absorbing particles. An antistatic material is added into the housing material of the module housing at where the sound-absorbing cavity is located, or the antistatic material is coated on the surface of the module housing at where the sound-absorbing cavity is located, and the antistatic material is either an electrically-conductive material or an antistatic agent. The speaker module of the present invention is capable of greatly increasing the fill rate of the sound-absorbing particles in the sound-absorbing cavity of the rear acoustic cavity of the speaker module, thus allowing the space of the rear acoustic cavity of the speaker module to be fully utilized and the sound-absorbing particles to fully exert the effects thereof in improving the acoustic properties of the speaker module, and greatly increasing the acoustic properties of the speaker module.
