1. A multifunctional sounding device, comprising:
a frame, comprising a top wall, a bottom wall opposite to and spaced apart from the top wall, and a side wall connecting the top wall and the bottom wall;
a vibrator assembly accommodated in the frame, comprising a vibrating unit suspended in the frame and vibrating along a first direction; and
a speaker assembly accommodated in the frame, comprising:
two magnetic units fixed to the frame and located on two opposite sides of the vibrating unit respectively, each magnetic unit comprising a magnetic gap;
a diaphragm fixed to the top wall and vibrating along a second direction, the second direction being perpendicular to the first direction; and
two voice coils located in the magnetic gaps of the two magnetic units respectively and driving the diaphragm for vibrating and generating sounds, a winding axis of each voice coil being perpendicular to the first direction and the second direction;
wherein the two magnetic units are sandwiched between the top wall and the bottom wall, a peripheral edge of the diaphragm is recessed inward for avoiding the two magnetic units.
