Abstract

1292707 Capacitor transducers PIONEER ELECTRONIC CORP 28 Aug 1970 [28 Aug 1969] 41614/70 Heading H4J An. electrostatic electroacoustic transducer, such as a push-pull loud-speaker, has two electrets 52, 62 facing each other with the facing surfaces oppositely charged and an electrically conductive vibratable membrane 7 positioned between them. Electrodes 5, 6 are connected tothe electrets 52, 62. The secondary of a transformer has one terminal connected to the membrane 7 and the other terminal connected to the electrodes 5 and 6.
