From June 24 to 26, 2026, SSA 2026 was grandly held at the Shenzhen Convention and Exhibition Center (Futian). AUDIOWELL showcased its comprehensive range of products for the smart automotive sector at Booth D03+D05 in Hall 3, presenting three core offerings—the AK2 ultrasonic sensor, the in-vehicle humidifier, and the haptic feedback actuator—which collectively demonstrate its full-scenario technological strength in smart vehicles, spanning from environmental perception to in-cabin interaction.
AK2 Ultrasonic Sensor: Redefining the Standard for Intelligent Driving Perception
The AK2 ultrasonic sensor is a new-generation automotive smart sensor independently developed by AUDIOWELL. Based on ultrasonic ranging principles, it represents the technological forefront of current automotive ultrasonic sensors.
In terms of ranging capability, the AK2 achieves a comprehensive breakthrough—with a maximum detection distance of 7 meters, a minimum blind zone as small as 15 cm, and a measurement accuracy of ±3 cm. Compared with conventional ultrasonic sensors, the AK2 "sees farther and sees clearer," delivering more precise environmental perception for ADAS functions such as automatic parking (APA/AVP) and low-speed cruising. It adopts the industry-advanced DSI3 communication protocol, enabling high-speed synchronous processing of multiple data streams and fundamentally resolving the industry-wide challenge of same-frequency interference between sensors. Through its unique ultrasonic signal coding technology, the AK2 can simultaneously transmit different ultrasonic signals, with a system refresh cycle of less than 40 ms, greatly improving system efficiency.
In terms of safety, the AK2 meets the ASIL-B functional safety level, complying with the highest automotive industry standards for safety. The product also features self-diagnostic capabilities, allowing real-time detection of signal transmission and reception to ensure safe and reliable operation even in complex environments. With technical advantages including longer ranging, smaller blind zones, codable frequency modulation, and adaptive thresholds, the AK2 has already been adopted in volume production by OEMs and is suitable for autonomous driving levels above AVP L2.
In-Vehicle Humidifier: Ultrasonic Atomization Technology Redefining the Smart Cabin Health Experience
AUDIOWELL extends its ultrasonic atomization technology to the smart cabin domain, launching an in-vehicle humidifier and fragrance system solution for the automotive front-loading market. This solution incorporates AUDIOWELL's self-developed intelligent atomization head, which integrates the atomizing plate and the circuit board, replacing traditional discrete atomization head designs.
In terms of technical characteristics, the solution offers outstanding advantages such as compact size, low power consumption, and minimal heat generation. The ultrasonic atomization is driven by a circuit that excites the piezoelectric ceramic vibrator to produce high-frequency axial mechanical deformation, rapidly accumulating ultrasonic energy on the liquid surface to generate micron-level fine mist. The product features a dry-burn protection function for safe and reliable operation, employs digital signal control, supports functional expansion and development, and can be connected to the vehicle's intelligent information system for automatic control or adjustment according to driver and passenger preferences. This solution brings a more comfortable and healthier in-cabin environment to smart vehicles.
Haptic Feedback Actuator: Leading the Transformation of Human-Vehicle Interaction
The haptic feedback actuator is another flagship product from AUDIOWELL in the field of smart cabin human-machine interaction. Leveraging the direct and inverse piezoelectric effects of piezoelectric ceramics, the actuator generates precise mechanical deformation under driving voltage, producing high-resolution localized haptic feedback.
In the field of automotive intelligent displays, the haptic feedback actuator can simulate extremely refined tactile effects—such as light touch, sliding, and pressing—delivering a realistic tactile sensation similar to mechanical buttons. Drivers can perform blind operations without looking at the screen, significantly enhancing driving safety and convenience. In steering wheel applications, AUDIOWELL's haptic solid-state button solution, centered on the haptic feedback actuator, recreates authentic tactile feedback through the direct and inverse piezoelectric effects, supporting intuitive adjustment of multiple parameters including vibration duration, amplitude, and frequency, with no fewer than six levels for each parameter. The solution also supports multiple interaction methods such as pressing, clicking, and sliding, and even allows two-level settings for the same button, making the tactile control experience more multidimensional and enriched.
Compared with traditional mechanical buttons and linear motor solutions, AUDIOWELL's haptic feedback actuator demonstrates significant differentiated advantages: energy consumption reduced by 10–13 times, product size downsized to millimeter scale, IP68 protection rating, and feedback effects customizable via software. The product can be integrated into the smart cabin domain controller, allowing vibration effects to be adjusted through various smart terminals such as mobile phones and iPads.
From Perception to Interaction: Full-Stack Enabling of Smart Vehicles
From the AK2 ultrasonic sensor for environmental perception, to the in-vehicle humidifier for cabin health, to the haptic feedback actuator for human-machine interaction, AUDIOWELL presented a complete smart automotive product matrix covering the entire "perception–health–interaction" chain at SSA 2026. Relying on its four manufacturing bases and proprietary core technology platforms, AUDIOWELL has built a comprehensive supply chain system encompassing sensitive materials, transducer chips, algorithms, and precision manufacturing.
Throughout the three-day exhibition, the AUDIOWELL booth D03+D05 remained consistently bustling, with professional visitors showing strong interest in the three products and engaging in in-depth discussions with the on-site technical team regarding product performance, customization requirements, and mass-production schedules. With this participation, AUDIOWELL not only comprehensively demonstrated to the industry its technological accumulation and innovative achievements in the smart automotive sensing and actuation sector but also continues to empower the high-quality development of the smart automotive industry with its full-stack solutions from perception to interaction.
