Claims (2)

일정한 거리를 이격하여 같은 극끼리 마주보게 고정시키고 마주본 자극사이에 보이스코일을 위치시켜 반발자기(磁氣)와 음성전류에 의하여 진동하도록한 동전형(動電形)전기 음향 변환기.A coin-type electro-acoustic transducer that is fixed to face the same poles at a certain distance, and that the voice coil is positioned between the opposite poles to vibrate by a repulsive magnetism and a voice current. 1항에 있어서 진동계의 중심을 유지하기 위하여 자극의 중심선상의 진동판에 자극과 마주보는 위치에 같은 자극이 가도록 작은 자석을 설치한 반발자기(磁氣)댐퍼(damper).The repulsive magnetic damper according to claim 1, wherein a small magnet is provided in the diaphragm on the center line of the magnetic pole so that the same magnetic pole is placed at the position facing the magnetic pole. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
