Abstract
An electromagnetic or electrodynamic shockwave source for generating acoustic shockwaves has a movable element which can be driven for generating the shockwaves, and a stationary element which is in electromagnetic interaction with the movable element to drive the movable element. A membrane which contains an electrical coil arrangement, the coil being charged with high-voltage pulses to cause the generation of shockwaves, is provided as the movable element. A component containing electrically conductive material is disposed opposite the coil arrangement, and is provided as the stationary element.
