Abstract: The loudspeaker module is installed in an interior of an electronic terminal and comprises an outer casing in which a vibration system and a magnetic circuit system are received, the magnetic circuit system comprises a basin-like stand fixed on the outer casing, a position of the outer casing corresponding to a sidewall of the basin-like stand is provided with a rear sound exit hole, the rear sound exit hole is communicated with an inner cavity of the module and an inner cavity of the electronic terminal; a chamfered plane is disposed at an upper end of a sidewall of the basin-like stand corresponding to the rear sound exit hole, and the chamfered plane is disposed on a side of the sidewall of the basin-like stand adjacent to the rear sound exit hole. The loudspeaker module according to the present disclosure solves technical problems in the prior art such as large volume and likely low-frequency distortion of the loudspeaker module.
