Abstract

Emisor macrosónico de placa vibrante, con reflectores y separadores de las zonas internodales para obtener radiación directiva en fluidos. Tipo de radiador macrosónico constituido por una placa rectangular que vibra flexionalmente excitada por un vibrador, piezoeléctrico, magnetostríctivo o de otro tipo y una estructura anexa, formada por separadores y reflectores, que sirven para poner en fase la radiación acústica emitida por los diferentes sectores internodales y por ambas caras de la placa vibrante, logrando una emisión direccional. Así se consigue un emisor acústico direccional, con alta capacidad de potencia (depende de las dimensiones de la placa), y alta eficiencia mecano-acústica. Este tipo de diseño es adecuado para emisión en aire en un rango de frecuencias de 0-20 kHz y para emisión en agua de 0-100kHz, donde los emisores con placa vibrante escalonada presentan dificultades por el elevado espesor del escalón lambda/2 que se requeriría.
