とするスピーカ。1. A diaphragm made of a thin plate-shaped conductive material whose peripheral portion is supported by a fixed portion and whose central portion is freely vibrating; A fixed voice coil that generates magnetic flux in a direction perpendicular to the second diaphragm according to the signal current, and a change in the magnetic flux generated by the voice coil generates an eddy current in the diaphragm. A speaker characterized in that the diaphragm is driven by an interaction between a magnetic flux and a magnetic flux generated by the voice coil.
