Abstract
PURPOSE:To make input-proof high without forming a coil in a narrow space by using a superconductive magnet fitted to a diaphragm and an electro-magnet generation magnetic force according to an inputted electric signal. CONSTITUTION:The superconductive coils 101a and 101b are winded to the superconductive magnets 10a and 10b, the magnetic force line occures in a direction A B and the polarity is also the same direction. The ordinary conductive coil 121 is winded to the electro-magnet 12 and the magnetic force line occures the direction A B. Thus, by the attracting force and the resiliency of the superconductive magnet and the electro-magnet generating the magnetic force according to the inputted electric signal, the diaphragm can be swung. A speaker of which input-proof is high can be made without forming the coil in the narrow space and without the occurence of coil cut caused by heat build-up.
