Abstract
PURPOSE:To make broad the piston movement area of a flat plate diaphragm and to increase the high frequency playback limit, by supplying a flat plane piston oscillation of the same voice coil bobbin to a flat plane diaphragm via a plurality of oscillation transmitting systems. CONSTITUTION:A drive cone 6 driven with a voice coil 4 of the same voice coil bobbin 3 is located in the inside of a drive cone 5 as an oscillation transmitting system, and the node of a flat plane diaphragm 1 is driven with the drive cone 6. In case of the drive with the drive cone 5, the band can be extended to the frequency immediately before the production of split oscillation at inner and outer sides taking the nodes of the plate 1 as boundary. In this case, the piston movement from the same voice coil bobbin 3 is delivered from the drive cone 6 in the inside of the node of the plate 1, the piston movement area can be extended, and high frequency playback limit can be increased.
