RESONANCE ACOUSTIC SYSTEM Russian patent published in 1999 - IPC

FIELD: sound production equipment. SUBSTANCE: device has sound source and resonant electroacoustic transducer which consists of housing, set of loudspeaker heads and acoustic reflectors which are shaped as disks which are located in opposite to speaker cones of loudspeakers along axis of resonator. One acoustic pair of loudspeaker and reflector is chosen as base on and is tune to basic tone. Other loudspeakers and reflectors are spaced from base ones by distance which provides comb-shaped amplitude-frequency response which maximums correspond to natural scale frequencies. This results in possibility in generation of overtones and suppression of dissonant constituents. Sound signal is spread in space as hyper-spherical acoustic waves. EFFECT: three-dimensional perception effect independently from position of hearer. 10 cl, 6 dwg
