Abstract: The present disclosure discloses a speaker module, comprising a module housing and a speaker unit disposed in the module housing, wherein the speaker unit divides a cavity enclosed by the module housing into a front acoustic cavity and a rear acoustic cavity, the module housing is further provided with an air-permeable insulation assembly which divides the rear acoustic cavity into a first chamber and a second chamber, and the second chamber is filled with a sound-absorbing material, and wherein the air-permeable insulation assembly comprises a support frame and a mesh cloth adhered and fixed to the support frame by means of a back adhesive. The present disclosure can be used to prevent the problems of mesh breakage and mesh deviation that are likely to occur when the mesh cloth is being installed at the air-permeable insulation assembly, thereby improving the production yield of the air-permeable insulation assembly.
