Abstract

본 발명은 평판형 스피커에 관한 것으로, 더욱 상세하게는 다수개의 자기회로가 수평으로 직렬 또는 병렬 연결되어 하나의 스피커로 되는 평판형 스피커에 관한 것이다. 본 발명에 따른 다수개의 자기회로가 수평 연결된 평판형 스피커는, 서로 다른 극성을 가진 한 쌍의 독립된 자기체가 2개 이상인 수평 연결 구조를 가지며, 상기 2개 이상인 자기체에는 보이스 코일들이 인쇄된 2 이상의 보이스 코일판이 각각의 자기체 사이에서 수평하게 종배열되며, 상기 2 이상의 보이스 코일판의 전류의 흐름은 동일한 방향을 유지하고, 상기 2 이상의 보이스 코일판 상단에는 가는 박막 형상의 2 이상의 진동-리드 플레이트가 서로 전기적으로 분리되어 위치되고, 상기 보이스 코일들과 상기 2 이상의 진동-리드 플레이트는 전기적으로 연결되어 이루어진다.
