Abstract

Se coloca un dispositivo impulsor (14) de una placa de vibracion acustica (11) entre una estructura (10) de altoparlante y la placa de vibracion acustica (11). El dispositivo impulsor (14) consiste de un par de placas de vibracion piezoelectricas (1, 2) arregladas frente a frente a cierta distancia. Las periferias externas de las placas de vibracion piezoelectricas (1, 2) se conectan entre ellas por medio de un espaciador anular (7). Cuando se aplica una senal de impulso a las placas de vibracion pieozelectricas (1, 2), las placas de vibracion piezoelectricas (1, 2) se encuentran sometidas a movimiento de flexion donde sus centros se flexionan alternativamente en direcciones opuestas. En este momento, las direcciones de flexion de las placas de vibracion piezoelectricas (1, 2) son siempre inversas entre ellas.
