Electronics digital Intelligent microphoneVESPER VM3011 intelligent digital microphone with Adaptive ZeroPower Listening is a disruptive power saving architecture that enables a 10 x extension of battery standby life with best-in-class acoustic performance. Device is based on firm’s patented piezoelectric MEMS transducer technology, which improves quality and performance. Adaptive ZeroPower Listening technology will automatically learn the acoustic characteristics of the environment in real-time, allowing the system to ignore background noise and only wake in response to keywords or other desired acoustic triggers. This allows the system to hibernate over 90% of the time and extend battery life >10x. Target applications for the device include IoT products, portable smart speakers, smartwatches, far field remote controls, security cameras, glassbreak sensors, automotive, medical devices and other battery powered systems.
