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.

Loudspeaker Failures and Protections (Part 1)

A new generation of effective and powerful speaker protection technology, using literally all the capabilities and power of pro sound rackmount loudspeaker management processors, is now being designed into mobile audio products that use very small loudspeakers. The implications are that mobile consumer electronics are going to play louder and sound better than ever. But to optimize speakers this way, we need to understand what causes loudspeakers to fail. This article was published originally in audioXpress, August 2013.
