Abstract

SE PRESENTA UN DISPOSITIVO GENERADOR DE SONIDO QUE INCREMENTA LA EFECTIVIDAD DEL SONIDO GENERADO ACOPLANDO MECANICAMENTE UN PESO (63) A UN ELEMENTO PIEZOELECTRICO (10). ESTE DISPOSITIVO GENERADOR DE SONIDO PUEDE ENCONTRAR UNA APLICACION PARTICULAR EN UN DISPOSITIVO GENERADOR DE SONIDO Y DE LUZ DE RESPALDO UTILIZADO EN UN VEHICULO AUTOMOVIL. TAMBIEN SE PRESENTA LA CIRCUITERIA (100) PARA MANEJAR UN ELEMENTO PIEZOELECTRICO (10) EN SU FRECUENCIA RESONANTE CUANDO LA SEÑAL DE CONTROL SE APLIQUE AL ELEMENTO PIEZOELECTRICO A LO LARGO DE UN TRANSFORMADOR DE CONFIGURACION (T1). LA CIRCUITERIA SUMINISTRA UNA SEÑAL DE REALIMENTACION QUE DETECTA LA FRECUENCIA EN LA CUAL ESTA VIBRANDO EL ELEMENTO PIEZOELECTRICO. ESTA SEÑAL DE REALIMENTACION SE EXPONE ENTONCES A UN FILTRADO DE PASO BAJO Y DE PASO ALTO PARA SEPARAR CUALQUIER DESPLAZAMIENTO DE FASE QUE RESULTE DE LA APLICACION DE LA SEÑAL DE CONTROL A LO LARGO DEL TRANSFORMADOR DE CONFIGURACION (T1). ESTA SEÑAL DE REALIMENTACION FILTRADA SE UTILIZA ENTONCESPARA CONTROLAR LA SEÑAL IMPULSORA.
