Abstract: A loudspeaker module, comprising a housing, and a sounding unit located in an inner cavity of the housing. The sounding unit partitions the inner cavity into a front acoustic cavity and a rear acoustic cavity isolated from each other, a sound hole communicated with the front acoustic cavity being further provided on the housing. The loudspeaker module further comprises a pressure relief channel which communicates the front acoustic cavity with the rear acoustic cavity and is acoustically sealed. The loudspeaker module of the present invention is provided with the pressure relief channel which communicates the front acoustic cavity with the rear acoustic cavity, and the pressure relief channel is acoustically sealed, such that a sound in the front (rear) acoustic cavity cannot be propagated into the rear (front) acoustic cavity so as not to cause an acoustic short circuit; and the rear acoustic cavity is communicated with the front acoustic cavity by means of the pressure relief channel, such that the rear acoustic cavity can balance the air pressure by means of the front acoustic cavity communicated with the outside. The present invention also relates to a terminal device comprising the loudspeaker module. The waterproof effect of the terminal device is good.

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.
