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.

xMEMS Labs introduced Montara Pro, a MEMS microspeaker with an integrated solution that opens or closes the vent by sensor fusion input from the system DSP. This approach enables smart TWS earbuds and hearing aids that create best-of-both-worlds user experiences, combining the benefits of closed-fit (occluded) and open-fit earbuds. xMEMS is providing first demonstrations of Montara Pro this week at the Consumer Electronics Show in Las Vegas at Venetian Suite 29-325.

xMEMS Labs introduced Tomales, a new monolithic, 1mm-thin profile MEMS tweeter µspeaker, available with top and side-firing package options that simplify speaker placement and positioning to direct audio toward the ear in smart glasses and augmented/extended reality headset applications. This new MEMS driver, which uses the company second generation M2 speaker cell architecture, has an IP58 rating for dust/water that simplifies system integration in these designs.
