'Beat' uses a viscoelastic polymer that is soft and bendable until it is subjected to an audio range of 20Hz to 20kHz.

Fujifilm unveiled a new film that can be used as the diaphragm or vibrating plate of a speaker at Nano Tech 2013 in Tokyo. ‘Beat’ makes it possible to realize a flexible speaker that can be folded or rolled up like a piece of paper.

As soft materials absorb vibration, Fujifilm used a viscoelastic polymer that hardens when subjected to the audible range of 20Hz to 20kHz, and otherwise remains soft so it can bend and fold.

Geek.com notes that the polymer is combined with piezoelectric ceramics, electrodes, and a protective outer layer. When a voltage is applied to the electrodes, the piezoelectric ceramics vibrate and the polymer functions as a diaphragm.

Fujifilm displayed three versions at the trade show; a slim speaker, a retractable speaker that can be rolled up, and a speaker that looks like a traditional Japanese fan.
