MIT engineers have developed a paper-thin loudspeaker that is not only portable, but capable of transforming just about any surface into an audio source. Despite how thin it is, this loudspeaker generates minimal distortion while using only a fraction of the energy required by its traditional counterpart. Best of all, it weighs as much as a dime and can generate high-fidelity audio regardless of the surface the film is bonded to.
The most surprising part of all is that fabricating this loudspeaker only requires three simple steps, all of which can be scaled up to the size required for use in an automobile. If this technology is used to cover an airplane cockpit, it could possibly provide active noise cancellation by generating sound of the same amplitude, but opposite phase, thus canceling each other out. Let’s just say that this is definitely as interesting as the Panasonic SoundSlayer.
- Full Range 2.0 Gaming Speakers: Optimized drivers built for full range sound and extreme clarity
- Custom 3" Woven Glass Fiber Drivers: Producting a tighter sound with higher frequencies, allowing you to hear disinct layers and audio details
- Rear-Facing Bass Ports: Deliver increased bass output for a fuller, richer range of audio
It feels remarkable to take what looks like a slender sheet of paper, attach two clips to it, plug it into the headphone port of your computer, and start hearing sounds emanating from it. It can be used anywhere. One just needs a smidgeon of electrical power to run it,” said Vladimir Bulović, the Fariborz Maseeh Chair in Emerging Technology, leader of the Organic and Nanostructured Electronics Laboratory (ONE Lab).
