+ | [* black] The first of the two microphones inside the iPhone (the one that you speak into) 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, lower profiles, and several mounting options. |
+ | [* black] Translation: This microphone is very small (3mm x 4mm) and is installed via surface-mount. |
+ | [* black] From a manufacturing viewpoint, a surface-mount design is valuable because it allows all the components to be integrated to the logic board all at once. This eliminates sub-assembly costs, and lowers the [http://en.wikipedia.org/wiki/Bill_of_materials|BOM] cost. |
