Chineses have created stereo speakers from carbon nanotrubok

Engineers from University Tsinhua in Beijing have created stereo speakers from carbon nanotrubok, writes «Lenta.ru».

Work of scientists is published in magazine Nano Letters. Feature of new devices is use distinct from modern dinamikov a principle of reproduction of a sound. It allows to do by their thickness about a usual paper.

The basic detail of new columns is the thin sheet weaved from carbon nanotrubok. When on a film pressure air round her sharply heats up and extends moves, creating a wave. Thegiven effect which has received the name of thermoacoustics, is not new: for the first time it has been noticed at a thin foil in the beginning of the last century. For practical application this effect then has appeared is too weak. In a case when instead of a foil the layer from nanotrubok appears, this effect in 260 times is stronger.

According to the developers, the new technology will be widely claimed in the modern world. She will allow to create the columns which have been built in in walls, ceilings, even clothes.

Let\’s remind, that in modern dinamikah the sound is born as a result of fluctuation of the special membrane named diffuzorom, fixed on a frame. The membrane is attached to the coil which moves in the field of a constant magnet, as a result of giving on it of an alternating current. Fluctuations diffuzora arise as a result of coil movement.
