Disclosed is a speaker module, comprising a module housing and a speaker unit accommodated within the module housing. A partition extends from the module housing to a module cavity. The speaker unit is mounted in the module cavity via the partition. Also, the speaker unit and the partition divide the module cavity enclosed by the module housing into a front acoustic cavity and a rear acoustic cavity. Provided on the partition is an acoustically sealed pressure relief channel in communication with the front acoustic cavity and with the rear acoustic cavity. The pressure relief channel comprises a through hole provided on the partition. A protruding mesa is provided on the partition at where the through hole is located. A through first stepped hole is provided on the surface of the protruding mesa directly facing the through hole. On the interface between the first stepped hole and the through hole, the section profile of the first stepped hole encloses the section profile of the through hole. A pressure relief groove is provided on the surface of the protruding mesa. The pressure relief groove is extended from the first stepped hole to the edge of the protruding mesa.
