PMM-3738-VM1000-R


PUI Audio, featuring Vesper’s exclusive technology, presents the world’s first piezoelectric MEMS microphone. The PMM-3738-VM1000-R provides superior performance and quality in all environments.




PMM-3738-VM1000-RPMM-3738-VM1000-R Whats Inside


Features:
• Very-low noise floor for use in quiet environments
• Low part-to-part variation for array and beam forming applications
• High dynamic range for ultimate clarity in any sound environment
• IP57-rated for performance stability in any condition


Standard capacitive MEMS microphones are susceptible to dirt and water disrupting the internal diaphragm-backplate relationship. This negatively affects performance and can even permanently damage the capacitive MEMS microphone.

Manufacturers combat this by adding a membrane over the sound hole to prevent dust and water ingress. Unfortunately this adds cost, while decreasing sensitivity and changing frequency response.

The PMM-3738-VM1000-R from PUI Audio is inherently dust and waterproof by design. Without the need of performance robbing membranes, your product's audio experience is dramatically increased.

PMM-3738-VM1010-R


PUI Audio, with Vesper’s piezo technology, presents the 2017 Sensors Expo Engineering Excellence Award winning PMM-3738-VM1010-R:
The world’s first ZeroPower Listening™ piezoelectric MEMS microphone designed for ultra-low power always listening solution; delivering voice activation to battery-powered devices.


PMM-3738-VM1010-R


Features:
• ZeroPower Listening™ technology
• Full audio output on wake-up
• Capable of voice detection with just 9 µW operating power
• Extends Battery life up to 10x
• Dust and moisture resistant


The singled-ended PMM-3738-VM1010-R analog MEMS microphone features Wake on Sound™. Wake on Sound mode allows for detection of voice activity while consuming only 5 μA of supply current (9 μW of power). In Wake on Sound mode, a sound in the vocal band above the level threshold instantly alerts a processor of an acoustic event. The processor (DSP or Voice Processor) then switches the PMM-3738-VM1010-R into Normal mode with full audio output within 100 microseconds! Fast enough for the microphone to capture the triggering sound and pass it along for processing. This is the system architecture for ZeroPower Listening.


Wake on Sound delivers voice activation to battery-powered voice-interface consumer devices—while drawing nearly zero power—such as smart speakers, smart TV remote controls, smart headphones, and IoT smart home products.
