DIAPHRAGM FOR SOUND CONVERTER

摘要

The present invention provides a diaphragm for a sound converter which can improve middle and high range sound characteristics by increasing rigidity of a center part of a diaphragm and reducing the weight of the diaphragm. The diaphragm for the sound converter of the present invention comprises: a side diaphragm of which a center is punctured; a center diaphragm of which an edge part is overlapped with the side diaphragm; and a voice coil provided on the overlapped part between the side diaphragm and the center diaphragm. The present invention comprises: a side vibration portion having a ring-shaped protrusion; a center vibration portion positioned inside the side vibration portion; and a voice coil provided between the side vibration portion and the center vibration portion, the side vibration portion and the center vibration portion being formed with different materials.
