ABSTRACT:
Monophonic sound is transformed into a stereo pattern by arranging two reflectors on a common axis at a predetermined distance from each other with both facing in the direction of the sound. One reflector has a larger diameter than the other and is provided with a central aperture into which a tone generator is mounted and spaced from the smaller reflector.
