Abstract

PURPOSE:To make diameter of the voice coil drastically small by connecting the nodal circle part of the ring-shaped plate diaphragm and the disk-shaped plate diaphragm by use of the ring-shaped suspension. CONSTITUTION:The ring-shaped suspension 12 fixed to the nodal circle part by the divided resonance of the ring-shaped plate diaphragm 10, and the plate diaphragm 13 is mounted to the reverse side of the aforesaid suspension 12. And the coil pin 7 is mounted to the nodal circle part by the divided resonance of the diaphragm 13. In case the signal is applied to the voice coil 8 under the foregoing structure, the coil pin 7 vibrates, the diaphragm 13 vibrates, and furthermore the afore-mentioned vibration makes the diaphragm 10 vibrate through the suspension 12. In this case, the diaphragm 10 does not cause the divided resonance by the divided resonance frequency but characteristics of even sound pressure frequency can be obtained. Also, since the foregoing can be easily attained by driving the nodal circle of the diaphragm 13 whose diameter is much smaller than that of the diaphragm 10, it is possible to make diameter of the voice coil small to approximately half, therefore the magnetic circuit becomes small-sized, as well, and the cost can be reduced.
