Abstract

L'invention concerne un haut-parleur-fréquence concave angulaire et à pavillon qui utilise deux têtes de diffuseurs fonctionnant en parallèle dans une gorge de pavillon commune s'élargissant radialement, d'où partent trois canaux à double réfraction individuels symétriques et convergents afin de diffuser les ondes sonores dans la direction de son ouverture de sortie. Le pavillon, ses composants et les canaux sonores ont une symétrie isométrique par rapport à un angle triédrique, ce qui assure une charge efficace et uniforme sur les têtes ainsi que la stabilité mécanique des diffuseurs lors de charges pics de pression sonore. Le pavillon doublement concave rallonge le trajet du son, ce qui permet d'obtenir une fréquence critique moindre et donc des dimensions moindres. La configuration à double membrane des têtes permet également de réduire la fréquence critique du pavillon pour des dimensions identiques en doublant la surface de sortie de la gorge du pavillon selon une compression donnée Sd/St (surface des diffuseurs/surface de la gorge). Plusieurs pavillons peuvent être regroupés selon un multiple de deux pour un rayonnement en 1A, XA, ou dans le volume complet d'un espace sphérique 4 p. Dans le cas de ce pavillon, on utilise une tête à double membrane avec un châssis monobloc et comprenant des capteurs de liaison électromécanique retour.
