This Solid-State Speaker Might Be the Future of Wearable Devices
What if a silicon computer chip could produce sound? That’s the idea behind xMEMS' Sycamore, a full-range, open-air, solid-state speaker driver that aims to revolutionize headphones, smart glasses, and other wearable devices. Magnetic speaker drivers—which we’ll call “conventionalspeaker drivers”—have remained largely unchanged over the past century. They’re pretty simple, too: a copper voice coil is manipulated by an electrical current to vibrate a diaphragm and produce sound. There are some constraints to this conventional design....
