xMEMS and Rayking Partner on Cypress + Alta-S Module to Accelerate Adoption of the World’s First Full-Range MEMS Speaker in Wireless Earbuds
xMEMS Labs today announced a strategic partnership with Dongguan Rayking Electronics Co., Ltd. to co-develop a turnkey Cypress + Alta-S speaker module for next-generation TWS earbuds. The collaboration follows xMEMS’ milestone achievement of bringing Cypress – the world’s first full-range MEMS speaker – and its companion Alta-S ASIC to mass production readiness.
The new module, to be shown for the first time at xMEMS Live Asia 2025, combines the unmatched acoustic clarity and lightning-fast mechanical response of Cypress’ piezoMEMS architecture with Rayking’s acoustic packaging expertise and manufacturing scale. This ready-to-use module simplifies design, reduces time-to-market, and enables OEMs to confidently mass-produce solid-state MEMS-based earbuds at scale.
By combining xMEMS’ core MEMS speaker technology with a fully packaged module, xMEMS and Rayking are accelerating the adoption of Cypress-enabled earbuds – bringing the clarity, precision, and durability of silicon MEMS speakers to consumers faster than ever.
The new Rayking module (Codename: Monster) marks a breakthrough in earbud design and performance, enabling brands to confidently mass-produce full-range solid-state MEMS-based TWS earbuds at scale, without relying on legacy coil-and-magnet dynamic drivers. The module dimensions are D10mm*H2.8mm including all external components and cover.
Availability
The Cypress + Alta-S module from Rayking will be available for sampling immediately following xMEMS Live Asia. Mass production shipments are scheduled for early 2026.
