Wireless headphone customers continually demand better sound quality, more powerful noise cancellation, a more comfortable fit, and longer battery life. Existing electromagnetic drivers, however, have already been optimized to their physical limits. Drivers based on dielectric elastomer actuators would enable significantly improved bass response and more compact assemblies, delivering superior noise cancellation and sound quality while also allowing more space for battery capacity and increasing design flexibility.
The team is seeking commercialization partners to develop a proof-of-concept device and support further testing of characteristics important for consumer products.
