On-Device Voice Interfaces Driving Growth in MEMS and ECM Microphone Market

According to SAR Insight & Consulting, the market for MEMS and ECM microphones continues to see strong growth, with ten billion units shipped in 2020. This was driven by two main factors: increased use of voice interfaces and multiple microphones per device, according to SAR’s latest report “MEMS Microphones Focus: Market Growth, Mic Type, Input Type, SNR, Volume, Performance Density.” With the emergence of TWS, earbuds and headphones are now the second largest market.

In this article, George Ntanavaras explains how to build a turntable speed measurement device using a microprocessor-controlled device that measures the speed of a turntable's platter. The project uses an Arduino board and the Arduino software IDE, and a micro sensor manufactured by Omron to sense the platter rotation.

OMRON Corporation of Kyoto, Japan released its new MOS FET relay module G3VM-21MT, the first electronic component in the world to adopt a "T-type" circuit structure, consisting of compact-size and longer-lifecycle solid state relays that output signals using no physical contact, therefore minimizing the leakage current that has long been a problem with semiconductor test equipment. The new G3VM-21MT relay contributes to reducing maintenance frequency of test equipment, allows high-precision measurements, and improves productivity of electronic components.
