Abstract
Un circuito excitador, para la excitación de medios funcionales,tales como, un LED, un zumbador, un convertidor de voltaje o una lámpara EL, que tiene un inductor (1030, 1130, 1230, 1330, 1730), un primer y segundo punto de conexión, para la conexión de las fuentes de voltaje, medios de conmutación (104O, 1140, 1280, 1380, 1740) los que cuando se encuentran en el primer estado, permiten que una corriente eléctrica fluya desde el primer punto de conexión y a través del inductor, para de este modo cargar el inductor con energía y cuando se encuentran en un segundo estado, substancialmente evitar que fluya una corriente eléctrica desde el punto de la primera conexión al inductor, en donde la función de al menos dos medios funcionales (1060, 1020, 1023; 1160, 1120 - 1123; 1360, 1320 - 1323; 1760, 1721) son activados cuando se descarga la energía desde el inductor hacia el medio funcional, CARACTERIZADO porque uno de los medios funcionales es una membrana que genera una onda acústica cuando la energía es descargada desde el inductor. Un circuito de excitación de acuerdo con cualquiera de las Reivindicaciones precedentes, CARACTERIZADO porque incluye al menos un medio de conmutación para el control de la descarga de energía desde el inductor a una cantidad seleccionada de medios funcionales.
