| Zusammenfassung: | A loudspeaker is disclosed with a diaphragm and an annular moving coil fastened to the diaphragm. An annular permanent-magnet system is arranged concentrically relative to the moving coil and is fastened to a support. To obtain a high-power and extremely slim system, the moving coil surrounds the permanent-magnet system with only a small air gap and, on its outer surface, carries a thin-walled annular core of amorphous metal. The permanent-magnet system consists of two permanent-magnet rings spaced from one another by means of a soft-mangetic annular intermediate disc and having like poles facing one another. |
