Abstract

EL INVENTO SE REFIERE A UN TECLADO CON UNA MULTITUD DE ELEMENTOS PIEZOELECTRICOS (3) EN FORMA DE DISCO, QUE SE ENCUENTRAN DETRAS DE UNA LAMINA DE CUBIERTA (2) EN ESCOTADURAS SOBRE UNA PLACA SOPORTE RIGIDA QUE ABARCA UNA PLACA DE ASIENTO Y QUE SE ENCUENTRA RELATIVAMENTE ENTRE DOS SUPERFICIES DE CONTACTOS (7,10). PARA CONSEGUIR UN TECLADO DE FUNCIONAMIENTO SEGURO Y SENCILLO, LAS ESCOTADURAS PARA LOS ELEMENTOS PIEZOELECTRICOS (3) SE DISPONEN DE FORMA ESCALONADA EN REBAJES (5) AL MISMO TIEMPO QUE LA PLACA SOPORTE PARA LA COLOCACION DE LOS ELEMENTOS PIEZOELECTRICOS (3) Y EJERCE UNA FUERZA DE PRESION DE LA PLACA CONDUCTORA (1) FORMADA DONDE EL DIAMETRO EXTERIOR MAYOR DE LA ESCOTADURA (5) Y ES ALGO MAYOR QUE EL DIAMETRO EXTERIOR DE LAS PLAQUITAS METALICAS (4) Y EL DIAMETRO INFERIOR ALGO MAYOR QUE EL DIAMETRO DEL ELEMENTO PIEZOELECTRICO (3) Y LA PROFUNDIDAD DE LAS ESCOTADURAS O ALOJAMIENTOS (5) EN LA ZONA DE SU DIAMETRO MAYOR SON ALGO MAYORES QUE EL ESPESOR DE LAS PLAQUITAS METALICAS (4) Y QUE EL ELEMENTO PIEZOELECTRICO (3). LA PLACA CONDUCTORA (1) ESTA EQUIPADA CON CARRILES CONDUCTORES (9,15) SOBRE SU CARA INFERIOR, DE LOS QUE ALGUNOS SON CONECTADOS A TRAVES DE CONTACTOS (8) DE FORMA INMEDIATA CON LA SUPERFICIES DE CONTACTOS (7) PARA LAS PLAQUITAS DE METAL (4) Y LOS OTROS SE ENCUENTRAN CONECTADOS A TRAVES DE CONTACTOS (14) CON LAS SUPERFICIES DE UNION (13) FORMADAS SOBRE EL LADO SUPERIOR DE LA PLACA CONDUCTORA (1), QUE A TRAVES DE LAS SUPERFICIES DE CONEXION (12) Y LOS CARRILES CONDUCTORES (11) ESTAN UNIDOS EN LA CARA INFERIOR DE LA LAMINA DE COBERTURA (2) CON LAS SUPERFICIES DE CONTACTOS (10) PARA LOS ELEMENTOS PIEZOELECTRICOS (3)
