MEMS drivers are coming to open-wear devices like XR glasses, smart watches and earbuds

In addition to improved audio performance, another key advantage of Sycamore drivers is their ultra-compact size. xMEMS says these micro speakers are one-seventh the size of conventional dynamic driver and one-third of their thickness.

Sycamore is based on the same platform as xMEMS' Cypress driver for active noise cancellation (ANC) earbuds. This means the component uses ultrasonic waves to create full-frequency sound from a 1mm thin chip.

xMEMS vice president of marketing and business development Mike Housholder stated, "Everything that you get out of our in-ear speakers translates to Sycamore, so you'll get that benefit as well."

These new speakers provide a significant advantage for product designers aiming for sleeker devices, making future open-fit earbuds, smart glasses, and watches more attractive.
