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.IMPROVEMENTS INTRODUCED IN THE MANUFACTURE OF PLASTIC GRIDS FOR SPEAKERS. THE TYPE OF THOSE THAT HAVE A PLURALITY OF HOLES (2 AND 2 ''), AND WHICH ALSO INCLUDES IN THEIR BACK FACE A SERIES OF REINFORCEMENT NERVES. IT IS CHARACTERIZED BECAUSE THE REINFORCEMENT NERVES ARE DETERMINED BY A PLURALITY OF STRAIGHT NERVES (3) PARALLELS AND EQUIDISTANTS BETWEEN THEY ARE LOCATED IN THE SPACE COMPRISED BETWEEN TWO LINES OF HOLES, WHICH COMPLEMENT AND INTERLOCK THEM WITH 4 "S" MODE THAT RUN ALONG A LINE OF HOLES, ALTERNATIVELY EDGING THEM. THE DISPOSITION OF THE NERVES PREVENTS THAT THEY CAN BE SEEN FROM THE EXTERIOR, AT THE SAME TIME THAT THEY IMPROVE THE MECHANICAL RESISTANCE TO BREAKAGE AND THE FIDELITY OF SOUND.
