MEMS microphones improving HD audio
According to both WiSpry and Cavendish Kinetics, people's hands are constantly changing the parameters for good reception, especially since people are constantly fingering their touchscreens. That, combined with the high-bandwidth of the LTE signal, makes adaptive antenna tuning particularly useful for next-generation smartphones.
Also aimed at the smartphone market is a new generation of high-definition MEMS microphones from Akustica Inc. in Pittsburgh (a subsidiary of Bosch). The iPhone-5 is one of the few smartphones with support for wideband voice, with Sprint in the US the first to support it, but by this time next year nearly every carrier worldwide is aiming to support the crystal clear sounds of HD audio. To meet that growing demand for wideband handsets, Akustica has announced a whole line of MEMS microphones that facilitate HD audio in any smartphone, tablet, or other mobile device.
Akustica's new family of high-definition MEMS microphones have super-wide frequency response for crystal clear voice recognition and come in four varieties for every consumer electronics application.
