  • Publication number: 20030108855
    Abstract: A book device includes a book and a speech circuit. The speech circuit includes a printed circuit formed on a composite membrane affixed to the cover of the book. The composite membrane includes a first dielectric film on which a first circuit portion, including plural first circuit modules, has been printed and a second dielectric film on which a second circuit portion, including plural second circuit modules, has been printed. One of the films also includes a pattern of dielectric ink dots that insulate the first circuit modules from the second circuit modules. The pattern of ink dots is such that when a user presses an object in the book that overlies one of the first circuit modules, the conductive lines of the first circuit module contact the conductive lines a correspond second circuit module, thereby closing one or more switches of the circuit.
