USound demonstrated its fully developed ultrasonic sensing module, showcasing the potential of MEMS technology beyond audio applications. Displayed during the CES 2025 show, the module integrates USound's Conamara MEMS tweeter, Tarvos amplifier, and a third-party MEMS microphone. It uses ultrasonic waves for precise distance and proximity measurements, with calculations processed by proprietary firmware. Designed for commercial use, the module is compact at just 5 mm in diameter and 1.5 mm thick, making it suitable for space-constrained devices. Its energy-efficient operation and use of standardized components ensure scalability for applications in consumer electronics, robotics, IoT devices, and industrial systems. By delivering high accuracy through a flat frequency response across the ultrasonic spectrum, the module is an interesting solution for embedded sensing tasks.

USound also presented its Zero VDC technology, an innovation that allows its MEMS speakers to operate without a DC bias. This advancement increases sound pressure levels (SPL) while simplifying circuit design by reducing the required components, enabling cost reductions and simplified implementations. CES attendees observed live demonstrations of the ultrasonic sensing module and Zero VDC functionality, emphasizing their readiness for commercial deployment. We are awaiting USound's MEMS-based technology in commercial products to see how companies adapt its technology.
