从驻极体声电转换到驻极体电声转换的发展(待续)

Development from the Acousticelectric Conversion to Electroacoustic Conversion of Electrets(Continued)

从电-声、声-电转换的可逆特性出发,介绍了从驻极体声-电转换到驻极体电-声转换的发展。并结合实用产品,从原理、设计、特性等方面进行了阐述。

From the reversible characteristic of acoustic -electric conversion, and electric - acoustic conversion,the de- velopment from the acousticelectric conversion to electroacoustic conversion of electret is introduced. And combined with practical products from the principle, design, features and other aspects are described .
