Document Type and Number:
WIPO Patent Application WO/2016/184094
Kind Code:
A1
Abstract:
An electroacoustic conversion apparatus and an electronic device, comprising a moving-coil electroacoustic conversion unit (2) and a piezoelectric buzzer (3). The electroacoustic conversion apparatus has a moving-coil sound production structure and a piezoelectric sound production structure at the same time, and a piezoelectric sheet compensates a high-frequency frequency response of a vibration system, so that an electroacoustic conversion apparatus having a super wideband with good performance is realized.
