Abstract

EL INVENTO CONSISTE EN UN TECLADO LAMINAR CON UN GRAN NUMERO DE PIEZOELEMENTOS (6) EN FORMA DE LAMINAS. LOS PIEZO-ELEMENTOS HAN SIDO INSTALADOS DETRAS DE LA PLATAFORMA FRONTAL (1) Y ENTRE DOS LAMINAS FLEXIBLES (2 Y 4). ESTAS LAMINAS FLEXIBLES ESTAN PROVISTAS DE UNA SUPERFICIE DE CONTACTO (2A,4A) PARA CADA PIEZO-ELEMENTO. ESTAS SUPERFICIES DE CONTACTO SON CONECTADAS CON EL TECLADO MEDIANTE UN CONDUCTO PRINCIPAL (2B,4B). TAMBIEN HAY UNA PLATAFORMA DE TRANSPORTE (7) QUE DESPLAZA LAS LAMINAS (2 Y 4) Y LA PLATAFORMA FRONTAL PARA LA RECEPCION DE LAS FUERZAS EJERCIDAS SOBRE LOS PIEZO-ELEMENTOS (6) CONECTADOS CON LOS SIMBOLOS DEL TECLADO AL HACERSE PRESIONSOBRE LA SUPERFICIE FRONTAL (1). PARA LA FABRICACION DE UN TECLADO LAMINAR ECONOMICO Y DE ELABORACION SENCILLA, UNA DE LAS LAMINAS FLEXIBLES ESTA PROVISTA DE ANILLOS (5) QUE RODEAN LOS PIEZO-ELEMENTOS (6), EL GROSOR AXIAL DE ESTOS ANILLOS ES APROXIMADAMENTE EQUIVALENTE AL GROOR DE LOS PIEZO-ELEMENTOS CON FORMA DE DISCO (6).
