Description

전기음향 변환기
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 전기음향 변환기의 수직축을 따른 단면을 부분적으로 도시하는 전기음향 변환기의 정면도.

Claims (9)

  1. 하나의 축에 관하여 회전형태를 갖는 확성기 봉입물로 형성되여, 각각의 단부가 확성기로 밀폐되며, 두개의 확성기들이 봉입물의 축에서 뒤쪽을 맞대고 설치되어, 확성기들중 하나가 전력원으로 부터 공급되어 "능동"인 전기음향 변환기에 있어서, 나머지 홧성기가 "수동"이여 전원을 받아들이지 않으며, 상기 확성기의 움직임이 능동 확성기의 후면파로 부터 초래되여, 상기 봉입물이 이것의 회전축을 따라 수직으로 유지되고, 다른 한편으로 상기 봉입물이 확성기들의 전면파와 후면파의 공형 하지 않는 본질적으로 알려진 가요성 재료로 형성되는 전기 음향 변환기.
  2. 제1항에 있어서, 상기 봉입물이 지면으로부터 약 30Cm의 최소 높이에서 진동들을 전달하지 않거나 또는 상기 변환기와 공명하지 않는 임의의 수단에 의해 매달려있는 전기 음향 변환기.
  3. 제2항에 있어서, 상기 "능동" 확성기가 수직 봉입물위에 배치되는 전기음향 변환기.
  4. 제1항에 있어서, 두개의 확성기들이 직경이 각각의 확성기 직경보다 약간 큰 간단한 또는 복합 음향흡수재료로 만들어진 강성 디스크들상에 고정되며, 그 주위의 봉입물의 가요성 재료가 감는 전기음향 변환기.
  5. 제1항에 있어서, 상기 회전 봉입물이 전달된 콘(cone)형태를 갖는 전기 음향 전환기.
  6. 제1항에 있어서, 두개의 확성기들이 상이한 크기인 전기 음향 변환기.
  7. 제1항에 있어서, 봉입물의 높이가 동일한 봉입물의 평균직경의 두배와 실질적으로 동일하며 이것이 동일한 봉입물 체적인 전기 음향 변환기.
  8. 제1항에 있어서, "능동" 확성기가 최소한 21Cm와 동일한 직경을 갖는 전기 역학의 관통과 대역 형태인 전기 음향 변환기.
  9. 제1항에 있어서, 봉입물의 내부 측면이 최소한 수센티미터 두께 이상인 석면과 같은 음향 흡수재료로서 정렬되는 전기음향 변환기.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
