Abstract
A diaphragm with moving coil for electrodynamic transducers has in the center thereof a spherically-shaped portion and adjacent to the spherically-shaped portion a toroidally-shaped zone which may be provided with corrugations. An outwardly diverging, truncated cone-shaped collar is placed on the spherically-shaped portion. The collar may be of the same material as the diaphragm. The collar has a circular rim which is mechanically fixedly connected to the spherically-shaped portion. The circular rim of the collar has a smaller diameter than the moving coil.
