Bosch Sensortec Acquires MEMS Microspeaker Innovator Arioso Systems

Bosch Sensortec announced the acquisition of Arioso Systems, the Fraunhofer IPMS spin-off company that developed its own innovative sound transducer principle for miniaturized MEMS microspeakers based on the patented Nanoscopic Electrostatic Drive (NED) principle. With this acquisition Bosch expands from MEMS microphones to the attractive market segment of silicon microspeakers, soon to be at the core of new generation true wireless hearables.

Fresh From the Bench: USound Megaclite 4.0 UH-R2040 MEMS Earphones

Fresh From the Bench: USound Megaclite 4.0 UH-R2040 MEMS Earphones

The Megaclite 4.0 UH-R2040 is a reference design based on USound's Achelous UT-P2018 MEMS drivers, comparable in length and width to smaller balanced armatures, but thinner. They’re SMT reflow-compatible, so easy to incorporate into automatic assembly processes. Brent Butterworth listened, measured, and compared the performance of this new design against conventional in-ear products using established driver technologies. This article was originally published in audioXpress, October 2021.

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.

xMEMS Announces Cowell Microspeaker for TWS and Hearing Aid Applications

xMEMS Labs today introduced Cowell, the world’s smallest monolithic MEMS µspeaker, targeting the replacement of balanced armature drivers in true wireless earbuds and hearing aid designs. At just 22mm3, 56 milligrams, and with a 3.2mm diameter side-firing package, Cowell delivers an impressive 110dB SPL at 1kHz. Cowell is the first speaker to use xMEMS’ 2nd generation M2 speaker cell architecture offering improved SPL/mm2 enabling increased loudness in smaller form factors.
