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.Acoustic devices have members that extend transversely to the thickness and that are capable of sustaining bending waves, consequently causing the action due to the area distribution of resonant modes of a vibration of bending waves with the obtainable acoustic action of said member on a feature of desired acoustic frequency of operation, the stiffness area distribution includes the variation in it used to obtain desired locations for the bending wave transducers and / or good acoustic sounding action from inherently unfavorable limb shapes. The members are configured of a combined pistonic action and an excitation of waves of bending of mass and geometry.
