Zusammenfassung:	The present invention relates to a double injection diaphragm for a microspeaker having an internal ventilation hole in the coil attachment guide. The dual injection diaphragm provided in a microspeaker to reproduce sound comprises: a center diaphragm; a side diaphragm that has a ring shape with a perforated center and has an inner peripheral portion attached to the outer periphery of the center diaphragm, an outer peripheral portion attached to the frame, and a dome portion that elastically connects the inner periphery portion and the outer periphery portion and protrudes upward or downward; and a voice coil attachment guide attached to the inner periphery portion of the side diaphragm by double injection, wherein the voice coil attachment guide has a plurality of ventilation holes on the attachment surface with a voice coil. The present invention can reduce split vibration and improve THD characteristics by lowering air impedance and reducing temperature rise. 본 발명은 코일 부착 가이드에 내부 통기홀을 구비하는 마이크로스피커용 이중 사출 진동판에 관한 것이다. 본 발명은 마이크로스피커에 구비되어 음향을 재생하는 이중 사출 진동판에 있어서, 센터 진동판; 중앙이 천공된 링 형상이며, 센터 진동판의 외주에 부착되는 내주부, 프레임에 부착되는 외주부 및 내주부와 외주부를 탄성적으로 연결하며 위치하며 상방 또는 하방으로 돌출된 돔부를 구비하는 사이드 진동판; 및 이중 사출에 의해 사이드 진동판의 내주부에 부착되는 보이스 코일 부착 가이드;를 포함하며, 보이스 코일 부착 가이드는, 보이스 코일과의 부착 면에 복수 개의 통기홀을 구비하는 것을 특징으로 하는 코일 부착 가이드에 내부 통기홀을 구비하는 마이크로스피커용 이중 사출 진동판을 제공한다.
