Knowles engineers reduce microphone power consumption

The engineers at Knowles Corp. (NYSE: KN) said they have developed a new digital, micro-electro-mechanical systems microphone with the lowest power consumption on the market.

Ideal for consumer electronics, the new multi-mode MEMS microphone offers a high signal-to-noise ratio within the low power mode, which enables voice controlled applications and maximizes battery life.

The new microphone utilizes Knowles´ low power, “Always On, Always Listening” technology to provide a high SNR component with the lowest power draw in the world lower than the conventional analog microphone and analog-to-digital converter combination.

Compared to other solutions, this digital multi-mode microphone adds value to consumer electronics by delivering up to three times less power consumption than other digital microphones and is 20 percent smaller in size.

Knowles is a market leader and global supplier of advanced micro-acoustic solutions and specialty components serving the mobile communications, consumer electronics, medical technology, military, aerospace and industrial markets. For more information, visit
