| description | 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.
