Abstract

1353098 Electrostatic transducers PIONEER ELECTRONIC CORP 14 July 1971 [14 July 1970] 33137/71 Heading H4J In an electrostatic electroacoustic transducer both a fixed electrode and a vibratory electrode are electrets. Both embodiments described are loud-speakers but could be adapted as microphones. The push-pull arrangement shown comprises two fixed electrodes 11 and 17 and a vibratory electrode 12. The signal input 16 is coupled to the electrodes in push-pull fashion via a step-up transformer 15 as shown.
