Zusammenfassung:An electrostatic electroacoustic transducer includes a first structure, a second structure and a third electrode. The third electrode is located between the first structure and the second structure. The first structure includes a first driving element, a first spacer and a first diaphragm, and the second structure includes a second driving element, a second spacer and a second diaphragm. By providing an alternating voltage source, a transformer and a bias voltage, the electrostatic electroacoustic transducer with a dual diaphragm structure has a high efficiency and an enlarged range of audio frequency.
