Abstract
The shock wave source according to the invention has a membrane of an electrically conductive material which is connected on one side with a propagation medium and, on the other side, with a flat coil. The membrane is subjected to a mechanical prestress which acts radially on it by virtue of the clamping of its edge area by at least one member which has a projection which extends in a direction normal to the plane of the membrane.
