The Intelligent Microphone: The Next Generation of MEMS Microphone Technology

At the end of July 2020, audioXpress ran a product release on Vesper's VM3011 intelligent digital micro-electro-mechanical systems (MEMS) microphone. Its claim to fame is a power saving architecture that enables battery standby life that otherwise would be unattainable without the "smarts." There are another half-dozen developers working on integrating all sorts of capabilities within the MEMS mic package. This article, originally published in The Audio Voice newsletter, discusses those developments.

Servo-Control in Mainstream Audio: From Motional Feedback to the Bend-Sensor

Imagine a new class of speaker diaphragm position sensors that enable audio engineers to reduce distortion and extend bass response from studio monitors, soundbars, smart speakers, and even smartphone microspeakers. With the precision of laser displacement instrumentation, this sensor is located between a stationary component of the speaker and an appropriate moving part to provide an error correction reference signal back to the amplifier. Well, that sensor has already been developed. This article was originally published in The Audio Voice weekly email newsletter.
