Abstract

본 발명은 평판형 스피커에 관한 것으로, 보다 구체적으로는 1 개의 자기회로에서 2개의 보이스 코일판이 진동판에 진동을 전달할 수 있는 하나의 자석과 그 자석의 양측에 보이스 코일판을 결합시킨 평판형 스피커에 관한 것이다. 본 발명에 따른 n개의 자석과 n+1개의 보이스 코일판이 결합되어 형성되는 평판형 스피커는, 중심부에 위치되는 하나의 자석과; 상기 자석을 사이에 두고 양측에 상기 자석과 일정 간격으로 이격되어 형성되는 자성체로 이루어지는 한 쌍의 요크 플레이트와; 상기 자석과 하나의 요크 플레이트 및 상기 자석과 다른 하나의 요크 플레이트 사이에 삽입되는 보이스 코일이 형성된 2개의 보이스 코일판과; 상기 보이스 코일판의 상단부에 접촉된 상태로 상기 보이스 코일판의 진동을 받아 진동되는 진동판;을 포함하여 이루어진다.
