Audio Processor Offers MEMS-Enhanced Features

Feb. 16, 2011
The STA321MP audio processing chip connects directly to the latest miniature and MEMS microphones and provides a unique way of boosting performance from small, low-cost or even damaged speakers.

The STA321MP audio processing chip connects directly to the latest miniature and MEMS microphones and provides a unique way of boosting performance from small, low-cost or even damaged speakers. The device provides a second MEMS input that can be connected to a tiny sensor for detecting speaker movements. This allows designers to apply active-sound shaping using patented techniques to optimize speaker performance. In active-sound shaping, the processor compensates automatically for distortion or damage to the speaker enabling high-quality audio performance from over-driven speakers or from those with torn or restricted-movement cones. Available in a 7 mm x 7mm QFN, price for the STA321MP is $3 each/1,000. STMICROELECTRONICS, Lexington, MA. (888) 787-3550.
