Abstract

El radiador de sonido tiene un sistema distribuido por area de transductores acusticos multiples que tienen medios de excitacion individuales. Se puede utilizar un gran numero de transductores y pueden ser de cualquier tipo. Senales de excitacion producen radiaciones acusticas de fase diferente desde los transductores en distribuciones sobre el area del sistema que tienen naturaleza difusa deseada o particularmente sonorizada. Los medios que producen la senal de excitacion implican contenidos de frecuencia acustica mas elevada de desplazamiento de fase, y son adicionalmente operativos para accion en fase de al menos algunos de los transductores en la sub-area o las sub-areas del sistema para contenido de frecuencia mas baja.
