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.The active acoustic device comprises a panel element (11) with distribution of resonant flexion wave action modes, the acoustic performance is determined together as transducer means (31-34). The transducer element (31-34) is coupled to the panel element (11) in a marginal position. The arrangement is such that it results in an acoustically acceptable action dependent on said distribution of said active resonant modalities. The methods for selecting the location of the transducer, or improvements through the location of the marginalized localized support, are supported by the evaluation of an optimal or better operational interaction of said transducer element (31-34) and panel elements (11) according to the acoustic output parameters for the device such as an acoustic radiator.
