Abstract

Zvučni emitori, na odgovarajućim nosačima (11), imaju prostorno postavljene nizove mnoštva akustičnih transformatora (12) koji imaju individualna pogonska sredstva. Može biti upotrebljen veliki broj transformatora (najčešće preko 20, a često i preko 750 njih) i oni mogu biti bilo koje vrste (sa radom klipova, sa konusnim upravljanjem, elektrostatičkog ili pizoelektričnog tipa, oblika elektromehaničkog filma). Upravljački signali proizvode emisiju zvuka različite faze iz akustičkih transformatora postavljenih u nizovima oblasti koji imaju željenu difuznu ili posebnu glasovnu prirodu. Sredstva za proizvodnju upravljačkih signala uključuju fazno pomerene akustičke sadržaje viših frekvencija, i dalje su aktivne za jednovremeni rad bar nekih transformatora pod-oblasti vrste za nisko frekventne sadržaje.[Sound radiator has an areally distributed array of plural acoustic transducers having individual drive means. A large number of transducers can be used and can be of any type. Drive signals produce phase-different sound radiations from the transducers in distributions over the area of the array having desired diffuse or particularly voiced nature. Drive signal producing means involves phase-shifting higher acoustic frequency content, and is further operative for in-phase action of at least some of the transducers in sub-area(s) of the array for lower frequency content.
