Abstract
A sound generator for treating life forms with focused acoustical waves, characterized by an electrical drivable sound source, focusing arrangement for the acoustical waves coming from the sound source and an electrical generator arrangement for driving the sound source. The generator arrangement includes at least two different generators, which are connectible to the sound source by a switch arrangement and which will drive the sound source for generating different types of acoustical waves, for example shock waves and a continuous sound or acoustical wave. The sound source may be composed of a single transducer or a plurality of transducers.
