Abstract
UN DIAFRAGMA DE TRANSDUCTOR ELECTROMAGNETICO (110) QUE TIENE UNA CAPA CONDUCTORA ELECTRICA (221), CON UN MOTIVO CONDUCTOR, POSICIONANDO ENTRE DOS CAPAS AISLANTES (220,222) DE UN FLEXIBLE, MATERIAL ELECTRICAMENTE AISLANTE ENLAZADO JUNTOS PARA PROTEGER EL DIAFRAGMA. UNA CORRIENTE ELECTRICA PUEDE FLUIR A TRAVES DE LOS CONDUCTORES PARA PRODUCIR CAMPOS MAGNETICO Y ELECTROSTATICO ALREDEDOR DE DICHOS CONDUCTORES QUE INTERACTUAN CON UN CAMPO ELECTROMAGNETICO PARA PRODUCIR DESPLAZAMIENTO MECANICO DEL DIAFRAGMA QUE A SU VEZ PRODUCE UNA SEÑAL AUDIO. SE PUEDEN USAR SOPORTES NO FERROSOS PARA SOPORTAR EL DIAFRAGMA. SE PUEDE USAR UN IMAN O IMANES PARA CREAR EL CAMPO ELECTROMAGNETICO. LOS IMANES PUEDEN ENLAZAR CON LOS BRAZOS EN CRUZ DE LOS SOPORTES NO FERROSOS.
