MEMS microphones pass 300 million

Milestone in the history of MEMS microphone technology sees the shipment of the 300 millionth SiSonic surface mount MEMS microphone.

Knowles Acoustics has reached a major milestone in the history of MEMS microphone technology with the shipment of its 300 millionth SiSonic surface mount MEMS microphone.

Knowles Acoustics, which shipped its first MEMS microphone in 2003, has held the position as the leading supplier in MEMS microphone shipments for 15 consecutive quarters - nearly four years.

With an eye on shipping the next 300 million SiSonic MEMS microphones, Knowles Acoustics has many new products which will lead the way.

The popular 3rd generation Mini Series is now available with an integrated differential output for common mode noise reduction as well as an integrated switchable gain feature for hands-free applications.

The 4th generation Digital Series is ideally suited for applications where component density is at an absolute premium - such as mobile phones, digital still cameras, and MP3 players.

The Digital is a single bit, pulse density modulation (PDM) device, has an integrated sleep mode, and is compatible with stereo input applications.

Also on the horizon is the soon to be released 5th generation SiSonic - the Mini Zero Height.

The Mini ZHS is a miniature version of the award winning Zero Height SiSonic in a package 30% smaller than the original.

"Knowles Acoustics is proud to celebrate this historic milestone", said Jeff Niew, Vice President and General Manager of Knowles Acoustics.

"We have been able to quickly and smoothly ramp production for high volume applications such as mobile phones and other consumer electronic devices with high quality, innovative, cost effective microphone solutions".

"SiSonic is a proven technology and the most widely used MEMS microphone in the world".

"As the pioneer in the field of MEMS microphone technology, we are committed to continuing this track record with new, innovative products".
