Abstract
Dispositivos acusticos presentan miembros que se extienden transversalmente al espesor y que son capaces de sostener ondas de flexionprovocando consecuentemente la accion en razon de la distribucion de área de modos resonantes deuna vibracion de ondas de flexion con la accion acusticaobtenible retenida de dicho miembro sobre un rasgo de frecuencia acustica deseada operativa, la distribucion de área de rigidez incluye la variacionen el mismo utilizada para obtenerubica ciones deseadas para los transductores de onda de flexion y/o una buena accion acustica de modoresonante a partir de formas inherentemente desfavorables de los miembros. Los miembros está configurados de una accion pistonicacombinada y una excitacionde ondas de flexion de masa y geometría.
