Disclosed is a loudspeaker module, which comprises a loudspeaker unit and a peripheral frame comprising an upper housing and a lower housing; a front acoustic cavity and a rear acoustic cavity are respectively defined as a space between the loudspeaker unit and the upper housing, and a space between the loudspeaker unit and the lower housing; a sound hole in communication with the front acoustic cavity is provided on peripheral frame, and an inverted tube is provided in peripheral frame. The loudspeaker module of the present invention is provided with inverted tube in communication with rear acoustic cavity, so that low-frequency acoustic effect of products can be enhanced, and heat dissipation of rear acoustic cavity and balance of atmospheric pressures can be achieved; inverted tube and loudspeaker unit share front acoustic cavity and sound hole, which is beneficial to increasing size of loudspeaker unit and improving acoustic performance of products.
