Abstract:
The multifunctional sounding device provided by the present disclosure includes a housing body, a sounding unit and a vibration assembly. The sounding unit includes a frame, a vibration system fixed on the frame, and a magnetic circuit system that drives the vibration system to vibrate and produce sound in a first direction. The vibrator surrounds the outside of the magnetic circuit system with space. The coil assembly interacts with the magnetic circuit system to drive the vibrator to vibrate in a second direction perpendicular to the first direction. The coil assembly includes an iron core fixed to the vibrator and a coil wrapped around the iron core. The multifunctional sounding device of the present disclosure has a small thickness and low production cost.
