Patent Images
1. An electrodynamic shockwave source comprising:
- a housing containing an acoustic propagation medium;
a stationary element containing electrically conductive material disposed in said housing;
coil means movably disposed in said housing for interacting with said acoustic propagation medium and consisting of a membrane carrying a plurality of electrically conductive windings connected in parallel and otherwise insulated from each other, said membrane consisting of a plurality of layers and said windings being respectively disposed in said layers of said membrane; and
charging means for charging only said coil means with a pulse for causing rapid repulsion of said coil means from said stationary element to generate an acoustic shockwave in said propagation medium.

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.
