Abstract
SE PRESENTA UNA BOCINA ELECTRICA (50) QUE TIENE UN DIAFRAGMA (14) CONECTADO A UN EMBOLO FERROMAGNETICO (16) QUE ES IMPULSADO POR UNA BOBINA ELECTROMAGNETICA (36) PARA PROVOCAR LA VIBRACION DEL DIAFRAGMA EN LA FRECUENCIA DE RESONANCIA DEL DIAFRAGMA. UN CONTROLADOR (58) DE ESTADO SOLIDO TIENE UN TEMPORIZADOR (70) SINTONIZADO ESENCIALMENTE CON LA FRECUENCIA DEL DISPOSITIVO DEL DIAFRAGMA Y CONTROLA LA SALIDA DE LA CORRIENTE IMPULSORA QUE EFECTUA LA ENERGIZACION DE LA BOBINA PARA CONTROLAR EL MOVIMIENTO DEL DIAFRAGMA SIN DE FORMA SINCRONICA CON LA FRECUENCIA DEL TEMPORIZADOR. LA ETAPA DE LA SALIDA DEL CONTROLADOR COMPRENDE UN "MOSFET" DE CORRIENTE (80) O UN PAR DE "DARLINGTON".
