MIT develops a speaker thinner than sheet music –

If you get into cars, you may have heard of vinyl tapes, which can change the look of a car. MIT engineers took similar thin objects and made a thin film that could beautifully change any speaker. According to its creators, it can produce high quality sound with minimal energy consumption.

To achieve these properties, researchers have created innovative techniques. They claim that it can be upgraded to produce large enough headphones to cover the inside of a car or room wall, carrying the promise of an audible sound with no clear source. The auditory sensation in me is definitely feeling a hard cochlear coming. (Yeah, that’s a dick joke, but if your cochlear legs were hard you would be deaf, so anatomically it doesn’t make sense.

The loudspeaker can be used to interrupt active sound, for example – a combination of speaker technology and electronic devices and microphones, and can mute sound. The creators also measure the immersive sound experience, and in other cases use less energy such as smart devices, etc.

A thin film speaker produces a slightly distorted sound using part of the energy required by traditional loudspeakers. The hand-sized loudspeakers introduced by the band, which weighs as much as a dime, can produce high quality sound regardless of what the film surface is attached to.

“It feels amazing to take something that looks like a thin sheet of paper, attach two clips, connect it to your mobile phone and start listening to the sounds coming out. It can be used anywhere. needs a smidgeon of electrical power to manage it, ”said Vladimir Bulović, Chairman of Emerging Technologies Fariborz Maseeh, leader of the Organic and Nanostructured Electronics Laboratory (ONE Lab), director of MIT.nano and senior author of the paper.

Bulović wrote the letter to leader Jinchi Han, ONE Lab postdoc, and senior author Jeffrey Lang, Professor Vitesse of Electrical Engineering. The research was published today in the IEEE Transaction of Industrial Electronics.

Most thin-film speakers are set to stand because the film has to bend freely to produce sound. Installing these speakers on the surface will prevent vibration and impair their ability to create sound. To overcome this problem, the MIT team reconsidered the design of thin-film speakers. Instead of having all the vibrating elements, their design relies on small domes in a thin layer of piezoelectric that each shakes individually. These folds, each consisting of several strands of hair as a whole, are surrounded by blank layers at the top and bottom of the film which protect the surface while still allowing them to vibrate freely. The same layers of spacer protect the wound from scratches and impacts during the day-to-day treatment, extending the life of the speaker.

“We are able to accurately generate the mechanical activity of the air by stimulating the body surface to be balanced. The options for using this technology are limitless,” Bulović said.

There is no word on whether or when technology will see the light of day customer or business applications, but I would put it in my living room with heart-pounding voters just to get rid of the wires and speakers mounted on the wall.
