The updated release reads: GETTOP AND USOUND SIGN STRATEGIC SALES AND SUPPLY AGREEMENT USound, the technology leader in MEMS speakers and AI-based acoustic sensing solutions, and Gettop, a global provider of acoustic components, have signed a strategic supply agreement for MEMS wafer technology. Under the agreement, Gettop will manufacture MEMS speakers using USound’s MEMS wafers and ASICs. The agreement includes guaranteed production volumes and establishes a framework for close collaboration in sales and market development. By uniting USound’s pioneering MEMS expertise with Gettop’s strong manufacturing and market reach, both companies will strengthen their positions in the rapidly growing MEMS speaker industry and expand the technology’s global footprint. “This agreement marks a significant milestone, continuing to bring MEMS speakers to the mainstream,” said Ferruccio Bottoni, CEO of USound. “Partnering with Gettop allows us to further market adoption and unlock new opportunities for advanced audio applications.” The consumer electronics market is increasingly demanding semiconductor manufacturing standards, now also applied to loudspeakers. USound’s products are already integrated into consumer brands such as QCY’s MeloBuds N70 earbuds. In parallel, USound is expanding its innovation into health applications with an AI biosensing platform for true wireless stereo (TWS) devices, enabling advanced features such as heart rate monitoring. In addition, USound is advancing ultrasound-based applications, such as positioning, ranging, and object recognition, underscoring the versatility of its MEMS platform across multiple domains. Gettop also expressed its excitement to work with USound to bring its groundbreaking MEMS technology to a wider market. This collaboration enables us to provide next-generation audio solutions to customers around the world. The USound Gettop partnership marks a leap forward for the MEMS speaker consumer electronics market — from wearables to smart devices, and creating new opportunities for manufacturers while enhancing end-user experiences.
