Description

압전형 필름스피커의 스테레오 시스템
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음

Claims (1)

  1. 입력신호를 받아들이는 입력단과, 상기 입력단으로 인가된 신호를 좌, 우 스테레오 신호로 분리하는 스테레오 분리기, 분리된 신호를 각각 증폭시켜주기 위한 증폭기 및 증폭된 신호를 받아 음성신호를 재생시키는 스피커로 구성된 스테레오 시스템에 있어서, 상기 스피커는 압전형스피커(14)로서 다수의 압전진동소자(15)가 아아치형 필름 진동판(16)의 양측변에 나란히 배열되면서, 좌측 압전진동소자(15)는 좌측 증폭기(13)와, 우측 압전진동소자(15)는 우측증폭기(13´)와 각각 연결되어 각각의 음성신호를 재생하도록 된 것을 특징으로 하는 압전형 필름 스피커의 스테레오 시스템.
