[Asia Economy Reporter Park Sun-mi] DB HiTek announced on the 28th that it will begin full-scale mass production of MEMS (Micro-Electro-Mechanical Systems) microphone voice recognition chips.

MEMS refers to a technology that applies semiconductor manufacturing processes to simultaneously integrate ultra-fine mechanical components and electronic circuits, sized in micrometers (㎛, one-millionth of a meter), onto a silicon substrate. MEMS microphones are characterized by being smaller and consuming less power compared to conventional ECM (Electret Condenser Microphone), and their application range is continuously expanding from smartphones and tablets to wireless earphones and AI (Artificial Intelligence) speakers.

The product DB HiTek has started mass production of is an SNR 63dB (decibel) MEMS microphone voice recognition chip used in wireless earphones. Recently, the company also completed the development of a high-performance 65dB MEMS microphone product and plans to expand its business by entering the premium market. The higher the SNR value, the less noise there is, allowing more accurate sound recognition from greater distances.

A DB HiTek official stated, “DB HiTek is the only company in Korea capable of designing and producing microphone structures using an 8-inch based MEMS specialized process.” He added, “After reliability tests such as air pressure shock tests, drop tests, and constant temperature and humidity tests, full-scale mass production of the 65dB MEMS microphone product is expected to begin in the first half of next year, which will significantly contribute to sales growth.”
