Acoustic Intelligence
USound MEMS speakers are redefining what ear-worn audio systems can do.
USound MEMS speakers are redefining what ear-worn audio systems can do. Beyond delivering high-resolution sound, they enable compact multi-driver architectures and support new acoustic sensing functions through ultrasound and AI.
At ISEAT 2026, USound will demonstrate how MEMS technology can address different product requirements across TWS earbuds, open-ear devices and audiophile IEMs—from extended high-frequency reproduction and flexible speaker integration to sensor-free acoustic biosensing.
Experience the Latest MEMS Audio Innovations
From high-resolution audio to sensor-free biosensing, USound expands what product teams can achieve with a speaker.
Sensor-Free
Acoustic Biosensing
AuriSense uses ultrasonic signals generated by a USound MEMS speaker and captured by an inward-facing microphone to enable heart-rate monitoring and wear detection—without adding dedicated optical sensors.
Dual-Speaker
Audio Module for TWS
The Greip audio module combines a dynamic woofer with a USound MEMS tweeter in a compact 2-way architecture. It delivers extended high-frequency response up to 40 kHz, along with powerful low-frequency output, and is already used in commercial products such as the QCY MeloBuds N70.
MEMS Audio for IEMs
USound MEMS speakers give IEM designers a compact high-frequency transducer for hybrid and multi-driver architectures. Their fast transient response and extended bandwidth support detailed treble reproduction while opening new possibilities for driver placement and acoustic system design. It is already used in commercial products such as kiwiEars and Soranik.
MEMS Audio for OWS
AuriSense uses ultrasonic Open-ear devices must balance acoustic performance, mechanical integration, and awareness of the surrounding environment. USound MEMS speakers provide a compact, consistent transducer platform for developing thinner and more flexible OWS audio architectures.
Ultrasonic Sensing Solutions
USound’s ultra-thin Conamara MEMS speakers extend beyond audible sound to support ultrasonic applications such as acoustic sensing, indoor positioning, and human presence detection—all within a highly compact form factor.

Technical Presentation
Motion Artifact Mitigation in Audioplethysmography
Michele Lucchi, Hardware Developer at USound, will present a technical paper addressing one of the central challenges in acoustic biosensing: mitigating motion-related interference in audioplethysmography signals.
The presentation will provide insights into developing robust acoustic biosensing for ear-worn devices and its potential to support reliable physiological monitoring without dedicated optical sensors.
