May 13, 2025 – xMEMS Labs, the leader in piezoMEMS audio innovation and creators of the world’s first all-silicon micro speakers, today announced Sycamore-W, a new addition to the company’s Sycamore near-field MEMS speaker family, engineered for smart watches, fitness bands, and other wrist-worn wearables.
Following the successful debut of the original Sycamore µSpeaker in late 2024, Sycamore-W extends xMEMS’ commitment to µFidelity™ audio in space-constrained mobile form factors. Measuring just 1 millimeter thin in a 20 x 4mm form factor, Sycamore-W reduces speaker package volume by 70%, enabling dramatically slimmer, sleeker form factors while delivering high-quality, full-range sound.
“Sycamore-W redefines audio for smart watches, combining compact design with robust performance to meet the demands of next-generation wearables,” said Mike Housholder, xMEMS VP of Marketing and Business Development. “As the wrist becomes a key interface for ears-free, hands-free AI interactions, Sycamore-W empowers manufacturers to deliver premium audio in smaller, lighter, more durable devices.”
Optimized for Wrist-Worn Devices
Sycamore-W is engineered specifically for the unique demands of wrist-based wearables. Its 4mm wide x 1mm thin profile minimizes incursion into the watch cavity, enabling designers with the space to integrate more biometric sensors and larger batteries. Compared to legacy coil speakers that are typically 3 to 4mm thick and weigh up to 3 grams, Sycamore-W’s 150mg weight dramatically reduces strain and enhances comfort, both of which are key considerations for wearable devices.
Silicon Durability and Rugged Design
This new solution maintains the same solid-state durability xMEMS speakers are known for, with component-level IP58-rated protection and robust 10,000g mechanical shock resistance. These qualities make it ideal for active lifestyle wearables and outdoor-oriented smartwatches and fitness bands.
Sycamore-W measures 20 x 4 x 1.28mm. Samples are available now to early access customers, with volume production slated for Q2 2026. The original Sycamore µSpeaker will continue to serve broader applications, including smart glasses, open-fit earbuds, and laptops, while additional Sycamore family variants tailored to other specific applications will be announced later this year.
