Problem
Consumer electronics manufacturers face challenges in creating compact, high-performance audio solutions and effective thermal management systems within increasingly thinner device form factors. Traditional audio components and cooling methods often compromise sound quality, device efficiency, and design aesthetics.
Solution
xMEMS develops a piezoMEMS silicon platform that enables the creation of ultra-thin, high-performance audio and micro-cooling solutions. Their MEMS micro-speakers deliver enhanced clarity, detail, and spatial imaging for personal audio devices and smart wearables. xMEMS also offers active acoustic vents to balance occlusion effects and active noise cancellation (ANC) performance. The company's micro-cooling solutions feature the world’s first 1mm-thin, all-silicon, solid-state active micro cooling fan on a chip, designed for smartphones, tablets, and other thin mobile electronics requiring effective heat dissipation. xMEMS' piezoMEMS silicon solutions are based on the inverse piezoelectric effect, converting electrical energy to mechanical energy to generate airflow and/or pressure.
Target Audience
The primary target audience includes manufacturers of personal audio devices, smart wearables, smartphones, laptops, tablets, AR/VR goggles, and in-cabin automotive entertainment systems.
