U.S. Sound to raise $30 million to strengthen production of products for global brands

Graz, Austria–(Business Wire / Korea Newswire) December 17, 2021 — A company that develops and produces ultra-small loudspeakers based on MEMS (micro-electro-mechanical systems) technology Sound (USound) announced on the 6th that it had raised $30 million (25 million euros) for the mass production of second-generation MEMS loudspeakers aimed at global companies.

The investment is led by Austria’s leading venture capital firm, eQventure, with participation from venture capitalists such as Hermann Hauser (co-founder of ARM) and Longzhong Yang (co-founder of BYD) as well as European investment banks.

Ussound MEMS loudspeakers are applied to TWS earphones, headphones, smartphones, VR/AR glasses, wearables and hearing aids, and are 50% smaller than competing products and reduce energy consumption by 80%. Thanks to the smaller size, the size and weight of the wearable device can be reduced, providing a more comfortable fit and style. Thanks to the SMT reflow function, the quasi-sound MEMS speaker not only significantly reduces system cost, but also supports the highest quality and performance in audio products with a fully automatic assembly method. Ussound’s MEMS speakers are smaller in size than pure monolithic MEMS speaker production methods, but at the same time provide better sound pressure level (SPL) and sound quality while at a lower cost to manufacture.

“We are delighted to expand our product portfolio with the launch of the second-generation MEMS loudspeaker,” said Ferruccio Bottoni, CEO of Ussound. STMicroelectronics) and Audio Amplifier ASICs are being produced by TSMC (Taiwan), expanding the manufacturing network further.” “By working with the world’s best manufacturers, we will be able to increase production, increase efficiency and improve logistics processes to reach global customers,” he said.

Ussound develops and manufactures MEMS-based audio products for several global companies. The company’s products include the global TWS earbuds brand, hearing aid companies such as Shenzhen Magnet Technology Co., Ltd, augmented reality glasses from major technology companies with MEMS audio, and in-ear health monitors for HMS. Ussound also provides MEMS speakers for audio glasses such as Fauna, a fast-growing consumer fashion tech brand, positioning itself as the most sophisticated audio glasses on the market. Ussound also served as a technical partner for OPPO installation at ‘2021 Milan Design Week’.

Ussound’s second-generation MEMS speaker, which was newly announced on December 6, fully supports 3D spatial audio and can be produced as a waterproof speaker home appliance with a waterproof function to a depth of 3m. Ussound’s second-generation speaker was developed with a subsidy of 2 million euros from the European Commission’s (EC) research and innovation financial support program ‘Horizon 2020’.

Ussound opens up unprecedented industrial and product design possibilities with advanced MEMS sound solutions that combine high-quality audio with flexible design capabilities.
