A revolutionary material could the way we play and listen to sound in future, dramatically changing how speakers could work.
It’s called graphene, and its structure allows it to be made ultra-thin, while retaining electric conductivity.
Now, says The Verge, a new study at the University of Exeter is combining a speaker, amplifier and equaliser into one super-small graphene chip that could change speakers forever.
While traditional speakers use vibration to push air and create sound waves, The Verge says that this new technology would see the rapid heating and cooling of a graphene sheet, causing the surrounding air to expand and contract – ultimately creating sound.
The best part? The extremely thin nature of graphene would mean ultra-thin speakers in future, with incredible applications for consumer technology.
For instance, says the site, it could be incorporated directly into smartphone screens to create large, non-invasive sound systems on mobile devices.
