This is a new addition to the company’s Sycamore near-field MEMS speaker family and is engineered for smart watches, fitness bands, and other wrist-worn wearables.

Following on from the Sycamore µSpeaker, launched in late 2024, the Sycamore-W extends xMEMS’ commitment to µFidelity audio in space-constrained mobile form factors. Just 1mm thin in a 20 x 4mm form factor, it reduces speaker package volume by 70%, enabling much slimmer, sleeker form factors while delivering high-quality, full-range sound.

“With the Sycamore-W we are looking to redefine 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 helps manufacturers to deliver premium audio in smaller, lighter, more durable devices.”

The Sycamore-W has been engineered specifically for the demands of wrist-based wearables. Its 4mm wide x 1mm thin profile minimises 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, the Sycamore-W’s 150mg weight dramatically reduces strain and enhances comfort, both of which are key considerations for wearable devices.

This new solution comes with component-level IP58-rated protection and 10,000g of mechanical shock resistance making it suitable for active lifestyle wearables and outdoor-oriented smartwatches and fitness bands.

Samples are available now to early access customers, with volume production slated for Q2 2026.
