Carbon Nanotube Speakers Promise Applications Outside of Audio Equipment

Carbon Nanotube Speakers Promise Applications Outside of Audio Equipment

It’s been some time since we covered the use of nanomaterials in audio speakers . While not a hotly pursued research field, there is some tradition for it dating back to the first development of carbon nanotube-based speakers in 2008 . While nanomaterial-based speakers are not going to win any audiophile prize anytime soon, they do offer some unusual characteristics that mainly stem from their magnet-less design. Now a group of researchers at Michigan Technological University (MTU) have continued this tradition of tinkering with carbon nanotubes and speakers and walked away winning the Best of Show Award at SAE International’s Noise and Vibration Conference and Exhibition . While the MTU researchers have continued the trend of demonstrating a fairly rudimentary speaker design using the carbon nanotubes (CNTs), the real potential of their research may be in applications out...
