ABSTRACT:
A device for the generation of vortex rings which consists of a box supplied with orifices and electromechanic transformers. The electromechanic transformers are controlled by signalers and cause pressure waves within the box which form vortex rings at the orifices. As signalers low-frequency amplifiers can be used which send out music or speech signals or electronic circuits which form a kind of optimized signal.
