Abstract

Dispositif pour engendrer par voie électronique des phénomènes de radiation tournante d'un haut-parleur à l'aide de deux haut-parleurs distincts, ou de haut-parleurs combinés. A chaque haut-parleur est adjoint un amplificateur réglable. Ces amplificateurs reçoivent le signal basse fréquence d'une part directement et d'autre part à travers un organe retardateur. Le retard et le coefficient d'amplification des amplificateurs sont commandés en synchronisme par un générateur de signaux sous-audiofréquents. Application à l'équipement de salles de spectacle.
