Abstract

Un sistema y método para proveer sonido de ancho de banda completo a una audiencia en un espacio de audiencia ubicado frente a una pantalla de imagen acústicamente reflectante, tal como una pantalla de plasma, LCD, LED u OLED. El sistema de emisión de sonido provee dos fuentes de sonido separadas y espacialmente desplazadas, a saber, un altavoz de alta frecuencia (27) para reproducir componentes de alta frecuencia del sonido asociados con imágenes mostradas en la pantalla de imagen acústicamente reflectante y un altavoz de baja frecuencia separado (29). para reproducir componentes de baja frecuencia del sonido asociado a la imagen. El altavoz o altavoces de alta frecuencia se colocan frente a la pantalla de imagen para dirigir los componentes de alta frecuencia del sonido a la pantalla de imagen (25) en donde se refleja de nuevo al espacio de audiencia, mientras que el altavoz o altavoces de baja frecuencia se colocan en o alrededor de la pantalla de imagen acústicamente reflectante para dirigir los componentes de baja frecuencia del sonido hacia el espacio de audiencia (12).
