USound is a fast-growing MEMS speaker and AI-based acoustic solutions company that enables customers to build smaller, more efficient, and more capable audio products.

Founded in 2014, USound designed the world’s first MEMS speaker and has since established an international presence through teams and partners across Europe and Asia. The company’s value proposition centers on consistent acoustic performance, compatibility with automated assembly, ultrasonic functionality, and biosensing capabilities integrated into the audio chain.

USound’s portfolio includes MEMS speakers, audio modules, amplifier solutions, and AI-based acoustic biosensing features for ear-worn and wearable devices. Its products are designed for applications including premium IEMs, TWS and OWS earbuds, sleep earbuds, smart eyewear, and ultrasonic sensing.

USound MEMS speakers support high-resolution sound reproduction in compact acoustic systems and enable new design options for hybrid audio architectures. Beyond audio playback, they can also support ultrasonic acoustic biosensing through platforms such as AuriSense. The platform uses ultrasonic signals generated by a MEMS speaker and captured by an inward-facing microphone to enable sensor-free heart-rate monitoring.

USound’s MEMS speaker solutions are already integrated into commercial audio and wearable products from global brands.
