Abstract
An apparatus for producing audible sounds in response to visual indicia in the nature of an electronic book. The electronic book is constructed from a plurality of leaves which may be formed from a continuous accordion folded sheet or individual modular folded sheets joined back-to-back to form the pages of the book. During construction, a spacer is internally provided within each leaf to create at least one internal passageway opening at one end of the leaves at a location forming the book's spine. An electronic circuit having pressure sensitive switches and conductive paths is provided on the surface of a dielectric substrate using conductive ink. The switches are arranged on elongated members which are inserted into a respective internal passageway within the leaves of the book. By activation of a switch by pressure applied to visual indicia on the leaves, audible sounds are produced by an on board electronic module.
