Abstract

LA PRESENTE INVENCION SE REFIERE A UN DIAFRAGMA PARA UN TRANSDUCTOR ELECTRO-ACUSTICO, DEL TIPO ELECTRODINAMICO DE BOBINA MOVIL, PARA TRANSFORMAR LAS SEÑALES ELECTRICAS EN SEÑALES ACUSTICAS, Y DIFUNDIENDO LAS SEÑALES ELECTRICAS, CARACTERIZADO PORQUE EL DIAFRAGMA COMPRENDE UN ELEMENTO DE PALETA DE PIEZA UNICA, HECHO DE UN MATERIAL METALICO DE MUY POCA DENSIDAD Y CARACTERISTICAS EXCELENTES DE CONDUCTIVIDAD Y MECANICAS. LA PALETA METALICA ESTA SUSPENDIDA ELASTICAMENTE SOBRE EL PERIMETRO DE LA MISMA, ESTA ACOPLADA METALICAMENTE A LA UNIDAD DE LA CUAL FORMA UNA PORCION, Y SOPORTA EL HILO DE CORRIENTE ACUSTICA FIJO EN EL CENTRO DE LA MASA DEL MISMO RESPECTO A LA SUPERFICIE METALICA ACTIVA. EL HILO CONDUCTOR DE CORRIENTE ACUSTICA COMUNICA A LA PALETA EL CALOR QUE SE HA PRODUCIDO MEDIANTE LA CORRIENTE ACUSTICA, EL CUAL SE AÑADE AL GENERADO EN LA PALETA, PRINCIPALMENTE DEBIDO A LA DEFORMACION DE LA SUSPENSION ELASTICA. ESTE CALOR GENERADOR SE ABSORBE RAPIDAMENTE POR LA PALETA METALICA Y SE DISIPA EFICAZMENTE MEDIANTE IRRADIACION DE EL DENTRO DEL AIRE CIRCUNDANTE Y MEDIANTE CONDUCCION A TRAVES DE LAS MASAS ADYACENTES, MANTENIENDO CON ELLO LA TEMPERATURA POR DEBAJO DE UN NIVEL PELIGROSO.THE PRESENT INVENTION REFERS TO A DIAPHRAGM FOR AN ELECTRO-ACOUSTIC TRANSDUCER, OF THE ELECTRODYNAMIC TYPE OF MOBILE COIL, TO TRANSFORM THE ELECTRICAL SIGNALS INTO ACOUSTIC SIGNALS, AND DIFFUSING THE DIAGRAPH OF A DIAGRAPHY, WHICH DIAGRAINS THE DIAFRAY MADE OF A METALLIC MATERIAL OF VERY LITTLE DENSITY AND EXCELLENT CONDUCTIVITY AND MECHANICAL CHARACTERISTICS. THE METALLIC PALLET IS SUSPENDED ELASTICALLY ON THE PERIMETER OF THE SAME, IT IS METALLICALLY COUPLED TO THE UNIT IN WHICH IT FORMS A PORTION, AND SUPPORTS THE STRING OF ACOUSTIC CURRENT FIXED IN THE CENTER OF THE MASS OF THE SAME AS REGARDS THE ACTIVE METAL SURFACE. THE ACOUSTIC CURRENT CONDUCTIVE WIRE COMMUNICATES TO THE PALETTE THE HEAT THAT HAS BEEN PRODUCED BY THE ACOUSTIC CURRENT, WHICH IS ADDED TO THE GENERATED IN THE PALETTE, MAINLY DUE TO THE DEFORMATION OF THE ELASTIC SUSPENSION. THIS GENERATING HEAT IS ABSORBED QUICKLY BY THE METALLIC PALLET AND IS EFFECTIVELY DISSIPATED BY IRRADIATION OF ITSELF INTO THE SURROUNDING AIR AND BY PIPING THROUGH THE ADJACENT MASSES, KEEPING THE TEMPERATURE BELOW A LEVEL.
