Abstract

Selon l'invention, une colonne de haut-parleurs réflecteurs peut être mise en oeuvre en coopération avec une surface planaire à réflexion acoustique pour fournir une combinaison constructive d'ondes sonores directes et réfléchies produisant un champ sonore uniforme. Le champ sonore uniforme produit un champ sonore contrôlé dans les sens vertical et horizontal, ainsi qu'une uniformité de distances proche de la colonne de haut-parleurs réflecteurs à des distances éloignées. Les ondes sonores directes et réfléchies peuvent être combinées de manière avantageuse et constructive pour générer une largeur de faisceau focalisée d'ondes sonores. La colonne de haut-parleurs réflecteurs comprend une pluralité de haut-parleurs couplés à une surface de la colonne de haut-parleurs réflecteurs. La surface peut être constituée de manière à comprendre au moins une courbe présentant un rayon de courbure. La colonne de haut-parleurs réflecteurs peut être placée à proximité d'une surface planaire à réflexion acoustique, de sorte qu'un plan frontal d'un haut-parleur adjacent situé le plus près de la surface planaire à réflexion acoustique soit aligné perpendiculairement, et qu'un plan frontal d'un haut-parleur éloigné de la surface planaire à réflexion acoustique ne soit pas aligné perpendiculairement.
