Abstract

LA INVENCION SE REFIERE A UN CONVERTIDOR ELECTROACUSTICO QUE TRABAJA POR EL PRINCIPIO ELECTRODINAMICO, CON UNA MEMBRANA (8) QUE ESTA UNIDA A UNA BOBINA (9), EN QUE LA BOBINA (9) SE LEVANTA EN LA RANURA ANULAR EXISTENTE ENTRE LOS POLOS DE UN IMAN (3, 4, 5). LA INVENCION SE CARACTERIZA PORQUE LA MEMBRANA (8) TIENE EN LA ZONA DE LA BOBINA (9) UNA PROLONGACION (11), QUE SE CONFORMA DE UNA SOLA PIEZA CON ELLA, A LA QUE SE FIJA LA BOBINA, CON PREFERENCIA MEDIANTE UN PEGAMENTO. ES VENTAJOSO QUE LA BOBINA (9) SE DISPONGA CON LA PARTE FRONTAL DISPUESTA EN LA PROLONGACION ANULAR (11).
