Knowles ( http://www.knowles.com ), the world`s first surface mount microphone manufacturers, uses its combined expertise in miniaturized microphone designs and complementary metal-oxide semiconductor (CMOS)/MEMS technology.
Until recently, designers of mobile phones and other portable communication devices only had one traditional option to achieve their audio objectives, the electret condenser microphone (ECM). This left designers with few options. The availability of CMOS/MEMS technology was a huge leap in the mobile phone industry.
CMOS/MEMS technology is smaller, uses less space, lowers profiles to enable a thinner product and eliminates the cost of offline subassembly required by ECM`s.
Knowles remains ahead of the game. We recently introduced our fourth generation of silicon surface mount microphones, including a new wave of digital solutions.
