Abstract
The invention provides a multifunctional sounding device having a housing body with a containment cavity and a sounding unit. The sounding unit includes a vibration system and a magnetic circuit system that drives the vibration system along a first direction. The magnetic circuit system includes a main magnet and a secondary magnet to form a magnetic gap. The multifunctional sounding device further includes an elastic assembly fixedly connected to the housing body, a weight connected to the elastic assembly, and a driving coil fixed to the weight and vibrating together with the weight along a second direction. The driving coil includes a first side edge and a second side edge disposed opposite to the first side edge. The device has both a vibration feedback function and a voice feedback function, which is beneficial to reduce the volume of the electronic device.
