1. A multifunctional sound device, comprising:
a housing;
a sound unit;
a vibrator; and
a coil;
wherein the housing comprises an accommodating cavity, and the sound unit is suspended in the accommodating cavity; the sound unit comprises a frame, a vibration system, and a magnetic circuit system; the vibration system is fixed in the frame, and the magnetic circuit system drives the vibration system to vibrate and generate sound along a first direction, where the magnetic circuit system comprises a magnetic gap; the vibrator is suspended in the accommodating cavity and disposed on one side, distal from the vibration system, of the magnetic circuit system, and the coil is assembled to the vibrator; the magnetic circuit system interacts with the coil to drive the vibrator to reciprocally vibrate in a second direction, and meanwhile, the magnetic circuit system drives the sound unit to reciprocally vibrate in the second direction; the second direction is perpendicular to the first direction.
