Turn Your Clothes Into Fabric Speakers 

Transforming your clothes into speakers sounds weird, but science is working hard to bring fiction to reality. Like most of the technological breakthroughs these days, this one also seems possible with the help of nanotechnology. Researchers at Beijing’s Tsinghua University noticed that sending an audio frequency current through carbon nanotubes resulted in good quality sound.

These “fabric loudspeakers” can work in a wide frequency range, without the requirement of any movable parts or magnets. The basis of operation here is the Thermoacoustic effect. Alternating current heats up the surrounding air, which then expands and contracts, creating the desired audio wave.
