Piezoelectric MEMS Microphone

PUI Audio, featuring exclusive technology developed by Vesper, presents the world’s first and only piezoelectric microphone providing superior performance and quality in all environments

Image of PUI Audio's Piezoelectric MEMS MicrophonePUI Audio’s PMM-3738-VM1000-R is a low noise, low part-to-part variation, high dynamic range, single-ended analog output low-noise bottom port piezoelectric MEMS microphone. This microphone consists of a piezoelectric sensor and circuitry to buffer and amplify the output. It is ideal for voice user interface, IoT products, wearables, smartphones, smart home devices, and other applications where low noise, high stability, and durability are desired.

  • Unique piezoelectric MEMS transducer
  • Very low noise floor
  • Low part-to-part variation
  • Extreme particle resistance
  • Fast startup time
  • High dynamic range
  • Stable performance in all conditions
  • Dust and water resistant to IP57

Instead of following the design of traditional capacitive MEMS microphones, trapping air and contaminants between layers, PUI Audio’s piezoelectric MEMS diaphragm travels freely with sound making for improved fidelity and noise-rejection. The PMM-3738-VM1000-R has a small 3.76 mm x 2.95 mm x 1.1 mm package and is reflow solder compatible with no sensitivity degradation.
