Provided is a multifunctional sounding device and an electronic device. The multifunctional sounding device includes a casing, a sounding body accommodated in the casing, a vibrator assembly and an elastic supporting member for suspending the vibrator assembly in the accommodating space and providing elastic restoring force. The sounding body includes a vibration system and a magnetic circuit system for driving the vibration system to sound. The elastic supporting member includes 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 and both fixed to the casing. A thickening member is arranged on each bent portion, and a sum of a thicknesses of each bent portion and the thickening member is greater than a thicknesses of the first supporting arm and the second supporting arm.
