静电超声波换能器及其应用刘镇清，魏墨（同济大学声学研究所）０引言超声波换能器是产生与接收超声波的器件。目前已发展了几种非接触的、有些还是宽带的超声波换能方式［１］，静电换能器便是其中一种。由于静电换能器结构简单，近十余年来各国学者努力探索它的适用性，... Electrostatic ultrasonic transducer and its application Liu Zhenqing, Wei Mo (Institute of Acoustics, Tongji University) 0 Introduction Ultrasonic transducers are devices that generate and receive ultrasonic waves. At present, several non-contact, some broadband or broadband ultrasonic transduction methods have been developed [1]. Electrostatic transducers are one of them. Due to the simple structure of the electrostatic transducer, scholars from all over the world have tried their best to explore its applicability in the past decade or so.
