Abstract: A loudspeaker module comprises a housing and a loudspeaker unit. A cavity for accommodating and fixing the loudspeaker unit is provided in the housing. The loudspeaker unit divides the cavity into a front and rear sound cavity. A sound hole is provided on the housing, which is connected to the front sound cavity by a sound channel, and the loudspeaker unit has a square structure. The sound channel comprises an inner end close to the loudspeaker unit and an outer end communicated with the sound hole. The width of the inner end is longer than three fifths of the length of a side, corresponding to the inner end, of the loudspeaker unit. The loudspeaker module of the present invention has the advantage of good acoustic performance.
