IPhone 4 Turns up the Volume for Innovative MEMS Microphone Technology
Highlighted by their adoption in Apple Inc.'s iPhone 4, microelectromechanical system (MEMS) microphones are set to achieve a more than 50 % increase in shipments in 2010 and a fourfold rise by 2014, according to the market research firm iSuppli.
Global MEMS microphone shipments are set to expand to 695.6 million units this year, up 57.7 % from 441 million in 2009. By 2014, shipments will rise to 1.7 billion units, four times the total for 2009.
MEMS microphones are tiny microphones that employ a pressure-sensitive diaphragm etched on a semiconductor using microelectromechanical technology. They are commonly employed in cell phones, headsets, notebook PCs and video cameras, replacing conventional electret condenser microphones (ECM).
"In a major milestone, Apple in 2010 employed MEMS microphones in the iPhone 4, the first time the company used the technology in the iPhone line," commented Jérémie Bouchaud, director and principal analyst, MEMS, for iSuppli. "Although Apple previously used MEMS microphones in the fifth-generation iPod nano released in 2009, the company exclusively had been employing ECM technology in the iPhone line. With this move, Apple in 2010 will become the world's second-largest buyer of MEMS microphones, behind Samsung Electronics Co. Ltd. Apple was the sixth largest buyer in 2009."
Although they are significantly more expensive than ECM devices, MEMS microphones provide a host of advantages in terms of size, scalability, temperature stability and sound quality.
The iPhone 4 employs two separate MEMS microphones for noise suppression, a technique that reduces background sounds to improve the clarity of voice communications. Although noise suppression has been available since 2006, the arrival of Motorola Inc.'s Droid as well as the iPhone 4 has caused the popularity of the technology and of MEMS microphones to soar. The majority of smart phones by 2014 will use two or more MEMS microphones.
The mobile handset market in 2010 is the largest consumer of MEMS microphones, ahead of notebook PCs. Headsets will form the third largest user of MEMS microphones, due to their use by Apple. By 2014, mobile handsets and notebook PCs will still be the largest application for MEMS microphones, followed by slate-type tablets, such as Apple's iPad.
Since establishing the business in 2003, Knowles Electronics has maintained dominance in the MEMS market, with the company set to account for more than 80 % of shipments. The company has benefitted from its strong intellectual property portfolio. However, competition is rising, with three of the world's five largest MEMS microphone suppliers now being Asian suppliers of conventional ECM AAC Acoustic Technologies Holdings Inc., BSE Co. Ltd. and Hosiden Corp. all of which recently added the product to their portfolio. An International Trade Commission ruling in November 2010 should make it easier for newcomers to compete with Knowles. A commission judge ruled that Knowles's silicon microphone patents were invalid.

Which of these is the best microphone?
Which of the following is the best microphone?
I'm recording people acting and sometimes I need to record it in noisy environments. I'm looking for a microphone which is the most unidirectional, picks up the least amount of background noise, and has the least amount of hissing/buzzing/static noise.
