Vesper is the leader in piezoelectric MEMS micrphones for consumer applications. 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, can achieve 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 higher SNR, better matching and a rugged waterproof ultra-small form factor.
