Set of two reports highlighting new designs and processes from the first two MEMS microphones suppliers

In this version of Apple iPhone, Knowles succeeds in integrating two MEMS microphones out of the three present in the phone. The third microphone is from AAC Technologies which was also already present in the previous iPhone 5.

Apple thus uses the same MEMS microphones suppliers for the iPhone 5S, but each of them modified the design and the manufacturing process of their components to improve them by making them more robust.

Compared to the microphone used in the iPhone 5, Knowles major changes include the number of transducers of the MEMS die (impacting directly the die size) and the thickness of the backplate.

On its side, AAC Technologies also modified the design of the MEMS die (still supplied by Infineon) and the thickness of key layers.

Discover in this set of two reports the latest evolutions from the first two MEMS microphone leaders. The two reports are also available separately.
