Vesper was founded to commercialize a revolutionary approach to MEMS microphones developed by co-founders Bobby Littrell and Karl Grosh at the University of Michigan. This superior microphone design aims to bring studio quality acoustics into handheld devices.
Vesper’s novel piezoelectric transducer design achieves unparalleled acoustic performance. Because piezoelectric structures only require a single active membrane layer, they are not affected by squeeze film damping, the dominant noise source in capacitive microphones. Our structures deliver higher SNR, better matching and a rugged waterproof ultra-small form factor.
