Abstract
METODO PARA PRODUCIR UN TRANSDUCTOR ELECTRO-ACUSTICO. CONSISTE EN ACOPLAR UNA CUBIERTA DELANTERA (10) SOBRE UNA TRASERA (20), EXTENDIENDO ENTRE ELLAS UNA MEMBRANA (21) DE LAMINA DE PLASTICO, UN DISCO DE AMORTIGUACION (22), UN DIAFRAGMA METALICO DELGADO (23), UNA UNIDAD DE ACTIVACION CON UN IMAN CENTRAL (50) Y UNA ARMADURA (34) SUPERPUESTA AL MISMO. EN EL MONTAJE SE DISPONE LA CUBIERTA TRASERA (20) CON UN REBORDE HACIA ARRIBA Y SE BAJA PARA MONTAR LA UNIDAD DE ACTIVACION. DE ESPECIAL APLICACION PARA TELEFONOS.
