Can you imagine your room that could reduce the noise made by your siblings? Well Jinchi Han, an electrical engineer at MIT, and his team created flexible loudspeakers that can be put on almost anything to reduce disturbing sounds.
This new invention is only as thin as a few sheets of paper and its lightweight, which can help allows the flexible speakers to be as big or small as desired.
Since the speakers are so flexible, many companies believe they can make T-shirts or other items out of them.
According to ScienceNewsExplores, the speakers are made with an electric current which sends nearby air molecules moving. As a result, it generates sound waves. Han explained that the vibrating air molecules are “the working principle for sound generation.”
“The bottom layer elevates the small domes so that they can vibrate freely even if the speaker is mounted on a surface,” Han said. “They can vibrate even if the surface is rough or curved. The upper protection layer is thicker than the domes are high”. Han notes that “if you touch the surface, you don’t need to worry about damaging these small structures.”
However, Han has said whilethat the new tech can help control noise more easily, it would be hard trying to cancel all the noise inside a room completely, as it it would take a lot of microphones and speakers, which can be very expensive.
Han states that you can stop unwanted sounds going into your room when sleeping or studying. So you can have a loud or quiet room whenever you want.
