Abstract
MEJORAS INTRODUCIDAS EN LA FABRICACION DE REJILLAS PLASTICAS PARA ALTAVOCES. DEL TIPO DE LAS QUE CUENTAN CON UNA PLURALIDAD DE ORIFICIOS (2 Y 2''), Y QUE ADEMAS INCLUYE EN SU CARA POSTERIOR UNA SERIE DE NERVIOS DE REFUERZO. SE CARACTERIZA PORQUE LOS NERVIOS DE REFUERZO ESTAN DETERMINADOS POR UNA PLURALIDAD DE NERVIOS RECTOS (3) PARALELOS Y EQUIDISTANTES ENTRE SI QUE SE UBICAN EN EL ESPACIO COMPRENDIDO ENTRE DOS LINEAS DE ORIFICIOS, LOS CUALES SE COMPLEMENTAN Y ENTRELAZAN CON UNOS NERVIOS CURVADOS (4) A MODO DE "S" QUE DISCURREN A LO LARGO DE UNA LINEA DE ORIFICIOS, BORDEANDOLOS ALTERNATIVAMENTE. LA DISPOSICION DE LOS NERVIOS IMPIDE QUE PUEDAN SER VISTOS DESDE EL EXTERIOR, AL MISMO TIEMPO QUE MEJORAN LA RESISTENCIA MECANICA A LA ROTURA Y LA FIDELIDAD DE SONIDO.
