USound, the global leader in MEMS loudspeakers, today announced the showcase of its fully developed ultrasonic sensing module ...

The sensing device is a MEMS microphone that outputs a pulse density modulated (PDM) signal. There are chips available to directly interface such a microphone to a USB port, but [Mahesh] found ...

Deciding to go for a full digital design for the circuitry, the peripheral is based off of a MEMS microphone and an STM32 microcontroller doing the heavy lifting between it and a USB connection.

We use our leading position in SiSonic™ MEMS microphones, balanced armature speakers, and strong capabilities in audio processing technologies to optimize audio systems and improve the user ...
