	[* black] The first of the two microphones inside the iPhone is the Knowles S1950.
-	[* black] Knowles describes its [link\|http://en.wikipedia.org/wiki/Microphone#MEMS_microphone\|MEMS microphones] as being built with a patented CMOS/MEMS technology that allows for very small footprints for their packages, lower profiles, and several mounting options. What this means is a surface-mount mic that has a footprint of ~~XX by XX mm~~.

What this means is a surface-mount mic that has a footprint of 3mm x 4mm.
	[* black] For manufacturers, surface mount designs eliminate off-line subassembly production costs -- the mic is integrated directly to the logic board at the same time as the other components.
	[* black] Integrating the circuitry with the microphone lowers the BOM costs and simplifies manufacturing.
