All you need is a fever of heat than good vibrations.
Speakers are conventionally designed to make sound waves by the diaphragm pushing out air. According to researchers at the University of Exeter in the UK, this technology, which has been used for over 100 years, can be improved using Graphene.
To move the diaphragm and air of the speaker, a considerable amount of energy is necessary. It is said that it is for that reason that there is a difficulty in the quality of the tiny speaker that was powered only by the audio signal from the headphone cable. Thin Diaphragms can sometimes be broken, and many conventional speakers have been built on delicate technology.
According to the research of Exeter University announced the other day, it is a small chip covered with graphene that can replace. Graphene is a honeycomb ultra-thin and sturdy sheet formed by bonding carbon atoms. The tip is as big as the thumbnail and there is no moving part.
Graphene is rapidly heated and cooled, and the surrounding air expands and contracts to form a sound wave. By controlling the AC appropriately, it is possible to mix frequencies and amplify/equalize specific sounds, so this technology enables many household stereos such as amplifiers, equalizers, tower speakers, etc.
In addition, adding an invisible layer of graphene to the top of the liquid crystal panel can create a smart display that produces both images and sound at the same time, expand the area where graphene flexibility meets the skin, You can also expect to improve medical devices using ultrasound since maximizing signal strength .
Everyone who neither sticks to sound quality originally nor does not care about new technologies that utilized graphene in each industry.
