Abstract
A loudspeaker module includes a hollow main body, two rotatable connecting portions, and two loudspeakers. The hollow main body includes two opposite sidewalls. Each of the opposite sidewall defines a first opening, an inner sidewall of the first opening defines an annular rotating slot. One end of the connecting portion extends an annular flange shaped corresponding to the rotating slot. The two rotatable connecting portions are respectively rotatably connected to the main body via the flange rotating about the rotating slot. Two loudspeakers are disposed in an end of the corresponding rotatable connecting portion away from the main body.
