Title: LOUDSPEAKER MODULE
Abstract:
Disclosed is a loudspeaker module. The module comprises a housing and a loudspeaker body located within the inner cavity of the housing. The loudspeaker body divides the inner cavity into a front acoustic cavity and a rear acoustic cavity which are isolated from each other; a metal sheet is embedded in the housing; an acoustically sealed pressure relief hole which is used for communicating the rear acoustic cavity with the external environment is provided on the metal sheet; screen cloth is provided on the side of the pressure relief hole away from the rear acoustic cavity. Since a metal sheet is embedded in the housing of the loudspeaker module provided in the present invention, the metal sheet is provided with a pressure relief hole, and the inner diameter of the pressure relief hole can be downsized according to needs, air pressure between the rear acoustic cavity and the external environment can be balanced and a good acoustic sealing effect can be achieved without additionally providing a pressure relief slot. In addition, the loudspeaker module does not need a cover over the pressure relief hole, and features a simple structure and high yield.
