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.

Unravelling the Technical Solutions in Waterproofing of Audio Devices

This article offers an interesting perspective on the challenges and solutions that the electronics industry in general and the audio industry specifically needs to consider when requirements for waterproof, moisture-proof, splash proof, weather-resistant, and sweat-proof are increasingly demanded by consumers. "While the marketing points on the box might claim IPx7, IP68, or sweat proof, from a manufacturing perspective, there are gaps in the different processes to achieve these standards," Lindberg writes. This article was originally published in Voice Coil, July 2020.
