researchers from Massachusetts Institute of Technology, Massachusetts Institute of Technologydeveloped paper-thin speaker technology. The novelty was revealed on the institute’s own news page last week and is described in a scientific paper written by Jinchi Khanpostdoc at ONE Lab, Vladimir BulovichHead of the Laboratory of Organic and Nanostructured Electronics (ONE Lab) and co-author Geoffrey Lang, professor of electrical engineering at Vitesse.

As described, the project is partly funded by a research grant from Ford Motor Company and support from Landlease, Inc..

How does it work?

According to the description, this new technology works differently than standard headphone speakers. OUR design A thin film speaker is a molded piezoelectric material that moves when voltage is applied to it and then moves air over it to create sound. The device has small domes made of this piezoelectric material that can vibrate freely to produce sound.

OUR MIT News explains that each dome has 15 microns highabout one-sixth the thickness of a human hair, which vibrate up and down at a distance of half a micron.

The study also indicates that the power consumption of the device is about 100 milliwatts of power per square meter of speaker area.

Applications

In addition to the logical potential of possible loudspeakers and microphones, research continues to point to the use of new technologies as Active noise cancellation in noisy environments. The cabin of an aircraft is used as an example, where the material can be set to produce a sound of the same amplitude but in opposite phase to cancel out the noise.

Another possibility is to create 3D sound in a theater or theme park. “It’s amazing to take something that looks like a thin piece of paper, attach two paper clips to it, plug it into your computer’s headphone port, and start listening to sounds coming from it. Can be used anywhere. Just some electricity to work.”the researcher explained. Vladimir Bulovich.
