What PUI Audio Inc does

PUI Audio, Inc. is a privately held, Ohio-incorporated audio, haptics, and sensor component manufacturer founded in 1972 as Projects Unlimited's Audio Products Division, headquartered in Fairborn, Ohio. The company designs and supplies electromechanical and MEMS components including speakers, receivers, ECM and MEMS microphones, piezo benders, transducers, indicators, ultrasonic sensors, exciters, MEMS pressure sensors, amplifier boards, and a full spectrum of haptic actuators (ERM, LRA, VCA, piezoelectric). Its MEMS microphones integrate specialized pre-amplification ASICs, achieving up to 80dB SNR and 135dB AOP, and its MEMS pressure sensors integrate piezoelectric elements directly on silicon for measurement applications.

The company serves OEMs across four verticals — medical (patient monitoring, diagnostic imaging, defibrillators, glucose monitors), industrial (charging stations, gas detection, construction equipment, elevators), security (metal detectors, retail alarms, intercoms, smoke alarms), and consumer electronics (touchless payment, ovens, baby rockers, sterilizers). Go-to-market is sales-led with an engineer-engagement model, combining direct OEM custom-solutions work with a global catalog distribution footprint across Digi-Key, Mouser, Avnet, Arrow, Sager, Master, Newark, and TLC Electronics.

Revenue is generated primarily through hardware unit sales of standard catalog components and professional services revenue from custom audio design, prototyping, testing, and manufacturing support. Custom solutions include 24-hour in-house 3D-printed prototypes, acoustic enclosure design, and full audio system analysis. Pricing is quote-based and not publicly disclosed, with samples available for engineering evaluation through direct request or distributor channels.
