Abstract: A book, mainly used by children and students, consists of a book and a speech circuit. A printed circuit board containing press triggers is placed inside the cover of the book. A number of speech switches in the book correspond to the positions of pictures in the book. In the book, the speech circuit includes circuit for storage and sound emission, a speaker and a battery, all of which are in a box-like container linked with the book. When reading the book, press a picture in a page, the speech switch would be switched on. Based on preset programs and storage, the circuit for storage and sound emission enables the speaker to read aloud the language of the page, which may be Chinese or foreign languages, etc. Corresponding to the content of the book, the sound can be dialogue between animals. This makes learning a language easy and interesting.

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.
