Abstract
Disclosed are an electrical-acoustic transformation device and an electronic device, including a moving coil electrical-acoustic transformation unit and a piezoelectric buzzer. The electrical-acoustic transformation device in the present invention has a moving coil sound generating structure and a piezoelectric sound generating structure. The piezoelectric plate compensates the high-frequency response of a vibrating system, realizing an electrical-acoustic transformation device with good performance and super wideband.
