Abstract

Un altavoz del tipo que tiene medios sensores para la determinación de la resistencia a la radiación del diafragma, expresada por la velocidad o aceleración del diafragma del altavoz y la presión del sonido a una distancia del diafragma y por lo tanto, por medio de una unidad de procesado de señales proporciona una señal de control a una unidad de filtro ajustando el rendimiento del altavoz de una manera adaptable a las características acústicas de la sala de audición, comprendiendo los mencionados medios sensores un micrófono para la detección de la mencionada presión del sonido, caracterizado porque el equipo sensor comprende medios de micrófono para la detección de la presión del sonido en al menos dos puntos con separaciones diferentes del diafragma, y por que se proporcionan los medios portadores para permitir que un mismo medio de micrófono se exponga de una forma efectiva y adecuada a la presión del sonido en cada uno de los al menos dos puntos.
