Flexible Speaker Rolls Up

Flexible Speaker Rolls Up

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.

Speaker - Foldable Fan

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.
