Photo: Nikkei.Net Japanese Mikasa Shoji Co. has developed a bendable and foldable speaker, which is made with a piece of cloth woven with copper wire and polyester fiber and magnets. The sound is generated by vibrating the cloth.
The cloth speaker is based on technology of Protro Co., a maker of flat panel speakers. A cloth speaker in the size of 5.5cm wide x 30cm long sells for about 15,000 yen (~$141).
