Abstract

The acoustically controlled light system, for music, has three filter channels (high, medium and low) coupled to the output circuit of a microphone (acting as acoustic detector) or directly to the loudspeaker reproducing the music. The outputs of the three filters are connected to a decoder which controls an array of e.g., 8 different-coloured lights according to the music frequencies. Power amplifiers are situated between the decoder outputs and the lights. The light bulbs may be located inside a transparent sphere or dome.
