Paper Flexpeaker

Taiwanese researchers at ITRI have produced a flexible paper speaker and aim to have them ready for next year, with the price down to around $20 per 8.5-inch by 11-inch sheet. The speaker is made by layering thin electrodes and a prepolarized diaphragm between two thin sheets of paper. Their first application, they hope, is to use the Flexpeaker in cars as soon as next year. Then, movie posters, with the soundtrack or movie trailer highlights playing as folks walk by. The frequency response is only 500Hz to 200kHz so these speakers are mainly meant for commercial applications.
