Abstract

본 발명은 진동판의 센터부의 강성은 높이면서, 무게는 저감하여 중,고역 음향 특성을 향상시킬 수 있는 음향 변환 장치용 진동판을 제공하는 것을 목적으로 한다. 본 발명은 중앙이 천공되어 있는 사이드 진동판, 사이드 진동판의 천공부를 덮으며, 가장자리 부위가 사이드 진동판과 겹쳐지는 센터 진동판 및 사이드 진동판과 센터 진동판이 겹쳐지는 부분에 장착되는 보이스 코일을 포함하는 것을 특징으로 하는 음향 변환 장치용 진동판을 제공한다. 본 발명은 대략 링 형상의 돌출부가 형성된 사이드 진동부, 사이드 진동부의 내측에 위치하는 센터 진동부 및 사이드 진동부과 센터 진동부 사이에 장착되는 보이스 코일을 포함하며, 사이드 진동부과 센터 진동부는 서로 다른 재질로 형성되는 것을 특징으로 하는 음향 변환 장치용 진동판을 제공한다.
