Piezoelectric MEMS microphone from PUI Audio

The Evolution of the High-Fidelity, Compact Microphone

Today’s Electronics Industry is filled with devices driven by voice e.g. smartphones, headsets, tablets, laptops, wearables which are designed for voice capture and voice control.

Until today, these devices were built with capacitive MEMS microphones that operate on principles that were developed almost one-hundred years ago.

Enter the piezoelectric MEMS microphone from PUI Audio:

Instead of following the design of traditional capacitive MEMS microphones, trapping air between layers, PUI Audio’s piezoelectric MEMS diaphragm travels freely with sound making for improved fidelity and noise-rejection.

Capacitive MEMS are also notorious for degraded performance due to dust and water ingress—losing up to 80% of sensitivity or failing completely.
PUI Audio’s MEMS microphone is dustproof and waterproof (IP68 rated), without the use of performance degrading mesh, and is built with better unit-to-unit consistency for array applications.
