CA 2645852

A sound reproduction system (10) is disclosed in which a sound barrier (14) defines a horn passageway having an upstream (22) and a downstream section (24). A driver (12) is mounted at the throat (16) of the upstream section (22) so that its rearward directed output communicates with the downstream section (24). Output from the upstream section and the rearward directed output of the driver are merged at a tap point located at the beginning of the downstream section. By altering the respective areas and lengths of the upstream and downstream sections a variety of different frequency dependent responses are obtained. In one example, low-frequency response systems of heretofore unobtainable compact size are realized.

L'invention concerne un système de reproduction sonore dans lequel une barrière sonore définit un passage de pavillon acoustique comportant une section en amont et en aval. Un circuit d'attaque est monté au niveau de la gorge de la section en amont de telle sorte que sa sortie dirigée vers l'arrière communique avec la section en aval. La sortie provenant de la section en amont et la sortie dirigée vers l'arrière du circuit d'attaque sont réunies au niveau d'un point de prise situé au début de la section en aval. En modifiant les surfaces et les longueurs respectives des sections en amont et en aval, on obtient une diversité de réponses différentes dépendant de la fréquence. Dans un exemple, des systèmes de réponse à basse fréquence d'une taille compacte impossible à obtenir jusque-là sont réalisés.
