Abstract

There is provided an electrodynamic sound transducer comprising a chassis and at least one diaphragm which is capable of vibrating and which at its edge has at least two oppositely disposed fixing portions for fixing the diaphragm to the chassis. The edge of the diaphragm is not connected to the chassis between the fixing portions so that the diaphragm can vibrate freely at those locations.
