Abstract

L'invention concerne un appareil de projection de son destiné à projeter un son dans un espace de réception de son, tel qu'une pièce ou une salle de spectacle, comprenant une unité de basses ayant un logement qui comprend au moins une cavité et au moins une unité d'entraînement de basses enfermée dans au moins une cavité et un orifice de sortie entre la ou les cavités à travers le logement vers l'espace de réception de son de telle sorte que les sons générés par l'unité d'entraînement de basses dans la ou les cavités peuvent être projetés dans l'espace de réception de son. L'appareil de projection de son comprend en outre une unité nacelle ayant un logement qui forme une cavité et une pluralité d'unités d'entraînement qui sont montées à l'intérieur de la cavité, le logement comprenant une face de projection de son ayant un orifice pour chacune de la pluralité d'unités d'entraînement. Un cône de chacune des unités d'entraînement est monté vers l'extérieur dans l'un des orifices. Un bras de support de suspension est fixé à l'unité de basses et s'étend à partir de l'unité de basses où, lors de l'utilisation, l'unité nacelle est suspendue dans un plan vertical par rapport à l'unité de basses à partir du bras de support de suspension. Une amélioration de la reproduction sonore haute fidélité peut être fournie par l'appareil de projection de son par l'unité de basses et le bras de support de suspension qui est fixé à l'unité de basses de telle sorte qu'une unité nacelle peut être suspendue au-dessus de l'unité de basses. Le bras de support de suspension est conçu pour réduire les vibrations ou le son provenant d'un déplacement de l'unité de basses vers l'unité nacelle et en combinaison avec un agencement de suspension de l'unité nacelle provenant du bras de support de suspension réduit une contamination sonore de l'unité de basses dans l'unité nacelle. De manière correspondante, le son et les vibrations reproduits par l'unité nacelle n'interfèrent pas avec l'unité de basses.
