Abstract

Dispositivo acustico que comprende un elemento dependiente de una accion de onda de flexion con distribucion ventajosa de modos de resonancia,donde el elemento tiene su área activa acusticamente y al menos parcialmente limitada por medios teniendo encuenta la naturaleza sustancialmentede fijacion en relacion a la vibracion de onda de flexion. La operacion puede ser por debajo de la coincidencia o por encima si se desea por losdispositivos acusticos activos aun más teniendo una localizacion ventajosa de medios transductores de onda de flexion determinado con referencia a y teniendoen cuenta tales medios de limitacion.Acoustic device comprising an element dependent on a bending wave action with advantageous distribution of resonance modes, where the element has its acoustically active area and at least partially limited by means taking into account the substantially fixing nature in relation to wave vibration of flexion. The operation can be below the coincidence or above if desired by the active acoustic devices even more having an advantageous location of transducer means of bending wave determined with reference to and taking into account such means of limitation.
