Audiowell

What Audiowell does

Audiowell (Guangdong Audiowell Sensing Technology Co., Ltd., 广东奥迪威传感科技股份有限公司, ticker 920491.BJ) is a Guangzhou-headquartered, Beijing Stock Exchange-listed designer and manufacturer of intelligent sensors and actuators founded in 1999. The company operates four production bases across Guangzhou (Panyu), Zhaoqing, and Jiangxi, and an engineering R&D presence in Lanzhou via a joint research institute with Lanzhou University's Physics School. Audiowell generated approximately RMB 600 million in 2024 revenue across more than 30 product lines spanning ultrasonic sensors, flow sensors, piezoelectric actuators, micro-cooling devices, and specialty medical/security sensors, and is valued at approximately RMB 5 billion on the public market.

The company's underlying technology platform is built on piezoelectric ceramic materials and ultrasonic sensing, including inverse piezoelectric effect actuation, multi-layer hot-press co-firing stack fabrication, MEMS ultrasonic microfabrication, and ultrasonic time-of-flight measurement algorithms. Core product platforms include ultrasonic proximity and ranging sensors (AK2 automotive radar with DSI3/ASIL-B for ADAS, MEMS ultrasonic PU0001 with 180° field of view), ultrasonic and vortex flow sensors (FS/FV/FC series), piezoelectric stacked actuators for precision positioning, micro piezoelectric cooling pumps (7x7x1.4mm), micro jet air fans (MUAF, CHIP FAN), and piezoelectric dispensing valves. In 2024, Audiowell launched the world's first mass-producible lead-free piezoelectric ceramic sensor developed with Lanzhou University, achieving EU RoHS and drinking water safety compliance as a regulatory differentiator.

Audiowell's business model is B2B hardware sales to enterprise OEMs and Tier 1 suppliers in automotive electronics, smart meters and water management, smart home appliances, AI/embodied intelligence thermal management, medical devices, industrial automation, and smart security/terminals. Pricing is project-based with no public list price; revenue is generated through product sales with recurring orders from design-in relationships. Go-to-market combines direct enterprise sales, presence at international trade shows (SENSOR+TEST Germany, SNEC Shanghai, SSA Shenzhen, ICMD Shanghai, Sensor Converge USA), and e-commerce storefronts (Amazon, Alibaba 1688, Taobao) for samples and SMB orders. In April 2026 the company formally expanded into AI server liquid cooling and embodied intelligence robotics — launching an AI flow sensor family and announcing its O+X strategy — and in June 2026 its Aoganshiwei subsidiary launched the Moxy AI-interactive embodied robot, extending the business from component supplier to consumer-facing robotics brand.
