A multi-functional sound-generating device, including an enclosure with an accommodating space and a sound outlet, a sound-generating unit in the accommodating space and a motor assembly. The sound-generating unit includes a cone frame fixed to the enclosure, a vibration system and a magnetic circuit system fixed to the cone frame. The magnetic circuit system has a magnetic gap, and can drive the vibration system to vibrate. The motor assembly includes a motor drive unit at periphery of the magnetic circuit system and spaced from the vibration system, and an elastic member fixed to the enclosure and configured to suspend the magnetic circuit system in the accommodating space. The motor drive unit can drive the magnetic circuit system to vibrate, and includes an iron core fixed to the enclosure and spaced from the vibration system and a ring-shaped solenoid fixed to the iron core.
