SAR Insight & Consulting Forecasts Technology and Market Potential for MEMS Speakers

MEMS microspeakers and earphone drivers could threaten incumbent audio technologies by 2025 as consumers desire smaller and less power-hungry devices. Four billion devices with seven billion speakers were shipped during 2020, it has been estimated, across multiple sectors, including automotive, mobile phones, home AV, and many others. MEMS speakers could revolutionize the audio industry, thanks to their small form factor and low power capabilities, according to market analyst SAR Insight & Consulting.

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.
