CA 2168980

The loudspeaker particularly comprises two-aperture radiator (1) containing paired in-phase counter-radiating apertures (4) and reproducing middle frequencies. Apertures (4) face each other, and their geometrical axis F is positioned vertically, while the distance between apertures (4) equals to at least the radius of aperture (4) but does not exceed the wavelength of the lowest frequency reproduced by paired apertures (4).

Le haut-parleur de l'invention comprend au moins une unité de source (1) à deux ouvertures présentant une paire d'ouvertures (4) co-phasées identiques à contre-émission, et reproduisant des fréquences moyennes. Les ouvertures (4) sont directement face à face, leur axe géométrique F est vertical, la distance séparant les deux ouvertures (4) n'étant ni inférieure au rayon de chaque ouverture (4) ni supérieure à la longueur d'onde correspondant à la fréquence la plus basse pouvant être reproduite par la paire d'ouvertures (4).
