xMEMS Samples Ultra-Small Full-Range Microspeaker

Back in January 2015, I gave a talk about MEMS loudspeakers, and I have regularly written about MEMS speaker progress. A half decade later, it seems we are finally now moving beyond the industry's joke that MEMS’ development progress can be measured in dog years: it takes 7 human years for each year of MEMS’ progress! The big news is xMEMS Labs, a company founded just in January 2018, has announced it is now in mass production of its Montara, a monolithic MEMS “µspeaker” with a slim 1mm profile, and announced Cowell, the world’s smallest monolithic MEMS µSpeaker, at just 1.15mm high and 3.2mm wide.
