USound MEMS speaker


USound and AT&S revolutionize the True Wireless Earbud Market with MEMS-based fully integrated audio modules.

The new audio modules will compete with current TWS products with up to 75% reduced size, up to 85% reduced weight, and improved sound quality.

USound, a global developer and manufacturer of micro-electro-mechanical systems (MEMS) loudspeakers for personal devices and wearable technology, announced an expanded partnership with AT&S Austria Technologie & Systemtechnik, a global leader in the manufacturing of high-end printed circuit boards and integrated circuit substrates, to manufacture USound’s new fully integrated audio module for True Wireless Earbuds (TWS).

This is an extension of the existing long-term partnership between USound and AT&S that began in 2015. AT&S currently produces the circuit board which mounts USound’s Ganymede and Conamara micro-speakers in its consumer products.

“Having a fully integrated audio module will take True Wireless Earbuds to the next level. It’ll reduce the form factor of earbuds dramatically, allowing them to be more ergonomic and opens the possibility of adding more embedded technology, such as sensors,” said Ferruccio Bottoni, CEO of USound. “AT&S offers high-end advanced packaging solutions for high-volume products enabling us to deliver this new audio solution already within 2022.”

The new TWS audio module is expected to be available by USound within the second quarter of 2022.
