摘要
A waterproof, tear-resistant accordion book with magnet covers that hold the book together, and adhere to magnetically susceptible surfaces. The book comprises an accordion-folded sheet of material that is tear-resistant and waterproof and can be preprinted or can be written upon. The covers are attached to the respective outer folded portions. The book also can be made with tear-off pages that extend beyond the covers, and can also be made to float by means of a buoyant layer. An alternate embodiment of the invention utilizes a thin plastic box contains containing audio components with a built-in keypad. The user inputs key combinations as printed in the book, and by virtue of a sound chip with pre-recorded sound, can hear played hundreds of phrases or sounds.
