Electroacoustic Transducer Using Corona Effect
This paper describes the electrical Corona discharge in the air and its application to sound reproduction. It shows that this phenomenon can be used for the realization of a full range, high accuracy electroacoustic transducer, which works as a pure acoustic pressure source. Moreover, this transducer can reach a high sound pre;ssure level with a great linearity, and can be directly driven by digital signals.
