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.

Method for making an electronic book for producing audible sounds in

A learning aid is provided which allows the user to selectively mute one part of a prerecorded multipart drama and substitute his or her voice for that muted part. A recorded copy of a composite of the unmuted prerecorded portions of the drama, the user's voice, and additional sound effects may thus be created. A voice sensitive microphone allows the period of time for the user's part to be flexibly varied and prerecorded control signals provide visible cues to the user that the part selected is imminent.

Electronic aid for reading practice

Apparatus for producing audible sounds in response to visual indicia

Flexible membrane switchcores (100, 100a,100b) including a conductive first circuit (180) having first traces (171-178;194;196) and a conductive second circuit (185) having second traces (186-192;195;197), first contact elements (107a-162a) formed as nonbranched integral sections of the first traces (171-178;194;196), and second contact elements (107b-172b) formed as nonbranched integral sections of the second traces (186-192;195;197).

Membrane switchcores with key cell contact elements connected together

A folded electroluminescent lamp assembly (37,65, 87) including an electroluminescent lamp panel (10,41,74, 89) joined to a flexible circuit panel (4,42,73, 88) folded over and joined to the lamp panel. A tail (5,43,79, 90) extends from the circuit panel. Conductive tracks (30-35,56-58,78) extend across the circuit panel and the tail and are connected to the electrodes of the lamp panel. An electrical power source for activation of the electroluminescent lamp panel is to be connected to the tail (5,43,79, 90).

Folded electroluminescent lamp assembly

An assembly combining a membrane switch and an electroluminescent lamp panel in which the lamp panel is attached to a circuit layer of the membrane switch.

Membrane switch combined with electroluminescent lamp panel

A multi-layered flexible switch wherein the electrical contacts are transversely remote from the area of the switch to be depressed.
