    Abstract: Disclosed in the present invention is a speaker module. The speaker module comprises a housing, and a speaker unit located within the inner chamber of the housing. The speaker unit separates the inner chamber into a front sound chamber and a rear sound chamber which are isolated from each other. The housing is embedded with a metal sheet, the metal sheet being provided with a pressure relief hole which is acoustically sealed and used for communicating a rear sound chamber and the external environment. The pressure relief hole is provided with a mesh on the side away from the rear sound chamber. The speaker module provided by the present invention has a housing embedded with a metal sheet, the metal sheet being provided with a pressure relief hole. The inner diameter of the pressure relief hole can be made small according to actual needs. The rear sound chamber and the external environment can reach an air pressure balance and have good acoustic seal effect without additional arrangement of pressure relief groove. Furthermore, the pressure relief hole of the speaker module does not need a gland. The structure is simple and the yield rate is high.
