1. A multifunctional sounding device, comprising:
a casing with an accommodating space;
a sounding body accommodated in the accommodating space, comprising:
a vibration system accommodated in the casing; and
a magnetic circuit system for driving the vibration system to vibrate and sound;
a vibrator assembly; and
an elastic supporting assembly for suspending the vibrator assembly in the accommodating space and providing an elastic restoring force for the vibrator assembly, comprising:
at least one elastic supporting member arranged between the vibrator assembly and the casing, comprising:
a first supporting arm fixed to the vibrator assembly;
bent portions bent and extended from both ends of the first supporting arm; and
second supporting arms extended away from the first supporting arm from one end of the bent portions away from the first supporting arm and both fixed to the casing;
wherein a thickening member is arranged on each of the bent portions, and a sum of a thicknesses of each of the bent portions and the thickening member is greater than a thicknesses of the first supporting arm and a thicknesses of the second supporting arm.
