Abstract

The present invention relates to electrodynamic devices comprising a diaphragm and a coil attached thereto with a terminal surface, more particularly microphones or loudspeakers. Direct bonding of the coil to the diaphragm is necessary if the coil holder on which the coil is wound is very thin-walled, or completely absent, as is particularly desirable in the case of microphones.
