Abstract

El dispositivo acustico activo comprende un elemento de panel (11) con distribucion de modalidades resonantes de accion de onda de flexion quedetermina el desempeno acustico junto como medios transductores (31-34). El elemento transductor (31-34) está acoplado al elemento de panel (11) en unaposicion marginal. La disposicion es tal de manera que resulta en una accion acusticamente aceptable dependiente de dicha distribucion de dichas modalidadesresonantes activas. Los métodos para seleccionar la ubicacion del transductor, o mejoras mediante la ubicacion de la sujecion marginal localizada, se apoyanen la evaluacion de una interaccion operativa optima o mejor de dicho elemento transductor (31-34) y los elementos de panel (11) deacuerdo con los parámetrosde salida acustica para el dispositivo como por ejemplo, un radiador acustico.
