On April 23, 2025, the Shanghai International Automobile Industry Exhibition grandly kicked off. AAC Technologies, a global leader in sensory experience solutions, showcases its vision for the future of mobility alongside its subsidiaries, Premium Sound Solutions (PSS), and Chuguang（Chuguang Auto Parts Co., Ltd.）. Under the theme of Experience the Future of Sound in Motion, AAC Technologies presents an all-encompassing proposal for enhanced experiential scenarios.
The joint booth of AAC Technologies and PSS attracts a diverse array of attendees, including Li Auto’s Executive Director and President, Mr. Ma Donghui, who, accompanied by key team members Meng Qingpeng, Liu Liguo, and Gou Xiaofei, experienced the groundbreaking “Mobile Concert Hall.” This state-of-the-art acoustic marvel, co-developed by AAC Technologies and PSS, features 51 speakers and 8 seat exciters, integrating a suite of industry-leading innovative functions. Notable capabilities include independent sound zones, AI-driven music track separation, in-vehicle echo cancellation and noise reduction, and adaptive transparency, positioning it as the first full-stack sensory solution for intelligent cockpits in the industry.
During the experience, the independent sound zone feature left a lasting impression on Mr. Ma Donghui and his team, providing each seat with an uninterrupted entertainment space, tailored to individual listening preferences. Both parties engaged in discussions about further enriching application scenarios and aim to deepen their collaboration, jointly innovating cockpit sound experiences.

Li Auto and AAC Technologies, along with PSS, share a deep-rooted partnership. Li Auto’s Li L9 model features a platinum sound system equipped with 21 high-quality PSS speakers, delivering an impressive 2,160 watts of amplifier efficiency. The tweeters with dual-folded aluminum diaphragms provide crystal-clear highs, while the mid-range speakers produce rich, full-bodied sounds that bring vocal and instrumental performances to life. The bass is both responsive and deep, ensuring an exceptional listening experience from every seat in the car. The Li Mega model also comes standard with 21 flagship PSS speakers, incorporating PSS’s Coscone technology to bend the sound basin for superior acoustic performance.
AAC Technologies firmly believes that outstanding speakers elevate baseline audio quality, while exceptional algorithms and tuning determine the upper limits of auditory experiences. For instance, the NLC PRO algorithm acts as a “speaker enhancement module,” boosting the performance of the entire vehicle’s speaker system based on the superior PSS speakers and thus enhancing the auditory experience. Additionally, the RichTap Space intelligent cockpit solution utilizes proprietary content recognition algorithms to add haptics to audio-visual content and notifications.
The foundation of these extraordinary experiences lies in AAC Technologies’ “hardware-level safety solutions,” which include MEMS microphones with high clarity, wide-view optical lenses featuring wafer-level aspheric glass (WLG), accurate sound pickup, and low signal-to-noise ratio, complemented with compact, high-performance, responsive wire-controlled brake and steering motors. These features empower advanced intelligent driving capabilities and provide multifaceted interaction points between the vehicle and its passengers, establishing a vital connection for physical AI.
On February 9, 2024, AAC Technologies completed the acquisition of 80% of PSS’s shares. This move accelerates AAC Technologies’ diversified expansion into the automotive sector and enhances its audio solution offerings. This acquisition not only enriches its product portfolio but also marks a significant transformation in its business development, generating synergies to solidify the group’s market position.
Recently, AAC Technologies acquired 53.74% of Chuguang, a leading Chinese manufacturer of electronic components and modules. This partnership will enhance the group’s comprehensive acoustic solutions and enable a full-cycle approach in vehicle acoustics, covering sound perception, processing, and playback. They aim to provide clients with superior products, technology, and intelligent manufacturing services.
Partnering for Progress——Setting New Standards in Intelligent Cockpit Sensory Experience
In 2022, AAC Technologies released the White Paper on Haptic Feedback System Evaluation, outlining a new paradigm for physical AI interactions in consumer electronics to actively drive industry transformation. At the Shanghai International Automobile Industry Exhibition, AAC Technologies, in collaboration with PSS, showcases the world-class “Mobile Concert Hall,” featuring 51 speakers paired with a range of hardware and solutions rooted in physical AI principles. Collaborations with Chuguang and Sennheiser further highlight cutting-edge advancements in the automotive audio field, showcasing AAC Technologies’ commitment to revolutionizing cockpit sensory experiences. AAC Technologies warmly invites guests to visit their booth (2.2H-2BD016) from April 23 to May 2, 2025 to experience the unparalleled charm of the “Mobile Concert Hall.”
