"Consumer technology continues to advance every year. Smartphones debut with on-device, AI-powered features, smart glasses project displays of your daily tasks, and smartwatches can help you treat a cold before you feel its wrath. However, dynamic drivers, which are inside all of these products, have remained largely unchanged over the last 100 years. Dynamic drivers are the small transducers inside your earbuds, headphones, smartphones, smartwatches, and smart glasses, and they use the fundamental laws of physics to deliver sound to your ears."
"A dynamic driver consists of a magnet, a voice coil, and a diaphragm, and it uses electrical signals to generate magnetic fields that move the diaphragm and coil, creating sound. Dynamic drivers are cost-effective, power-efficient, and leverage air displacement to reproduce the prominent bass response most consumers enjoy. The downside to dynamic drivers is that they take up space and weight within your headphones and earbuds, and can often distort sounds at high volumes, struggling to maintain clarity."
xMEMS designs and manufactures tiny MEMS chips that perform audio transduction and heat management for consumer devices. The chips can reproduce sound while replacing entire dynamic drivers, offering reductions in space, weight, and distortion at high volumes. The MEMS approach uses microfabrication to create miniature transducers that leverage different physical principles than traditional voice-coil drivers. The technology promises improved clarity, lower profile designs, and integrated cooling solutions for smartphones, earbuds, smartwatches, and smart glasses. Manufacturing partners face integration challenges and adoption remains gradual as device makers evaluate trade-offs in cost, performance, and supply chain readiness.
