Abstract

La présente invention se rapporte à un dispositif de diffusion sonore (300) comprenant un caisson unique (310) et, dans ce caisson unique (310), au moins deux sources acoustiques haute fréquence (320) superposées, et plusieurs sources moyenne fréquence et/ou basse fréquence (330) superposées et disposées à gauche et/ou à droite des sources acoustiques haute fréquence (320), les sources acoustiques haute fréquence (320) étant individuellement couplées à un guide d'onde (340) de sorte à générer un front d'onde vertical à courbure non constante figée. Un tel dispositif (300) permet de minimiser les discontinuités entre les sources acoustiques offrant une grande qualité de diffusion sonore (pas de lobe parasite), de diminuer considérablement le poids et le coût de fabrication et aussi une installation rapide ne nécessitant pas le réglage angulaire de chacune des sources acoustiques les unes entre les autres contrairement aux dispositifs actuels.
