Abstract
A toy or educational device includes front and back covers, a spine, a plurality of pages, a plurality of pressure sensors mounted in the front and back covers and a sound generator connected to the pressure sensors. The pressure sensors are responsive to the application of pressure to an aligned location of a page overlying the corresponding cover for actuating the sound generator to generate sounds associated with both the location of the sensor which is depressed and the page to which pressure is applied.
