Micro-speaker enables slimmer wearables

Sycamore-W, an ultra-thin near-field MEMS speaker from xMEMS, brings premium audio to smartwatches and fitness bands. With dimensions of just 20×4×1.28 mm, it reduces speaker package volume by up to 70%, freeing space within wrist-worn devices for additional biometric sensors or larger batteries. At just 150 mg, Sycamore-W also minimizes weight impact in space-constrained wearables.

Compared to conventional coil speakers—typically 3 mm to 4 mm thick and weighing up to 3 grams—Sycamore-W’s slim profile and low mass significantly reduce bulk. The lighter design minimizes strain and improves comfort for all-day wear.

With solid-state durability, the MEMS speaker offers component-level IP58-rated ingress protection and withstands mechanical shocks up to 10,000 g. It delivers zero phase delay and improved low-frequency response compared to dynamic drivers, exhibiting 1st-order decay—where output falls off more gradually (1/f vs 1/f², or –20 dB vs –40 dB from 2 kHz to 20 Hz)—for stronger bass performance.

Samples of the Sycamore-W are available now to early access customers, with volume production slated for Q2 2026.
