MEMS (Micro-Electro-Mechanical Systems) microphones are advanced miniature devices essential in mobile, ear, IoT, and automotive applications. As industry leaders, we offer microphones that feature ultra-compact sizes, low profiles, and various mounting options to suit diverse design requirements. Our microphones deliver high-quality audio with increased output capacities and digital solutions that minimize analog noise.

The MM30 is a MEMS microphone with several parameters that Knowles can modify programmatically, or trim, after manufacturing and before testing. This means that individual and matched microphones can be quickly customized for optimal performance in different applications. This document outlines the parameters that can be trimmed and how changes to these impact other performance parameters.
