Description

전기 음향 변환기
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1도는 본 발명의 전기음향 변환기의 실시예를 표시한 단면도.
*도면의 주요부분에 대한 부호의 설명
4:진동판 27:전면기실(氣室) 28:배면기실 30:누설공 32:보조기실 32a,32b:소기실 33:브리지 34:가는틈.

Claims (3)

  1. 음향을 받아서 진동하고 또 진동에 의해서 음향을 발생시키는 진동판의 전면부에 전면기실을 설치하는 동시에, 상기 진동판의 배면부에 배면기실을 설치하고, 이 배면기실의 배면부에 누설공을 통하여 연결된 보조기 실을 설치하고, 이 보조기실을 적어도 2분할하여 소기실을 형성하는 동시에 양소기실을 가는틈으로 연결한 것을 특징으로 하는 전기음향 변환기.
  2. 제1항에 있어서, 상기 보조기실은 상기 배면기실에 상기 누설공을 통하여 연결되는 소기실과, 그 이외의 소기실에 브리지에 의해서 분할되고, 상기 브리지와 보조기실의 배면부를 닫는 배면판과의 사이에 상기 가는 틈을 형성한 것을 특징으로 하는 전기음향 변환기.
  3. 제1항에 있어서 상기 보조기실은 유니트화하여 상기 배면기실의 배면부에 부착된 것을 특징으로하는 전기음향 변환기.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
