Following a year of private demonstrations of its novel MEMS speaker design, xMEMS Labs is now coming out of stealth mode with is first piezo-MEMS speaker. Montara is the name for what the company claims to be "the world’s first true MEMS speaker," using a monolithic process that eliminates calibration and driver matching, and is SMT-ready. Montara also offers full-bandwidth (20Hz-20kHz), and is fully water, dust and shock resistant.

In this article for Voice Coil focused on MEMS loudspeakers, Mike Klasco reviews a bit of the history of the technology and previews the evolution and impact on the audio industry in general. The article examines MEMS devices in general, provides a basic explanation of how the various types of MEMS speakers work, and what commercialization challenges are ahead.
