Leifeng.com (public account: Leifeng.com)·Jingxi has exclusively learned that smart glasses startup Shenzhen Qingmu Digital Technology Co., Ltd. (hereinafter referred to as Qingmu Digital) has completed a seed round of financing. The investor is Nanjing Shike, and angel round financing is in progress.
Qingmu Digital's first product is positioned in the workplace and office scenes. It adopts a binocular dual-waveguide display, a multi-microphone array, and a dual-speaker sound guide solution. It has no camera and the whole machine weighs 31.7 grams. At present, the hardware solution has been finalized and the engineering prototype has been completed. It has entered the EVT stage, the first version of the circuit board is lit, and the App closed-loop demo is running.
Qingmu Digital was founded in November 2025. The founding team are all from Tsinghua University. Their resumes cover companies such as XREAL, Honor and Alibaba, covering the entire chain of optical design, hardware mass production and consumer business operations.
Founder and CEO Li Long received a master's degree from Tsinghua University and was one of the first domestic AR glasses practitioners. After joining XREAL in 2019, he has personally experienced the iteration and mass production of three generations of AR glasses, creating the third generation XREAL Air, which ranks first in domestic shipments. In 2022, he joined Honor as a smart glasses system engineer (SE), and has successively led the viewing glasses of Honor and XREAL, as well as the MR glasses pre-research project benchmarking Apple Vision Pro, covering product definition, research and development promotion to final acceptance.
The other two co-founders complemented their experience in optical technology and consumer hardware respectively. Xiao Jiasheng is a Ph.D. from Tsinghua University, has published more than 20 papers, and holds more than 30 optical-related patents; Cao Zilan is a master's degree from Tsinghua University. As a former Alibaba senior operations expert, he has completely managed the commercialization of consumer hardware such as Tmall Magic Box from 0 to 1.
In the past year, the competition for lightweight glasses has intensified. The Yiwen G2 reaches 36 grams and the Thunderbird iO reaches 34 grams. Most of the paths are to cut off the camera or speaker, and exchange for weight by subtraction.
But this does not mean that the wearing problem has been solved. An industry insider told Leifeng.com·Jingxi that even if smart glasses weigh 30 to 40 grams, they are still twice as heavy as ordinary glasses, and it is still difficult to wear them for a long time.
In this context, the particularity of Qingmu 31.7 grams is that it retains a binocular display, multiple microphones and dual speakers - it is the lightest among publicly available products with the same configuration.
Different from purchasing mature module assembly prototypes, Qingmu chose to reduce the weight by starting from optical, acoustic and structural design: the waveguide sheet was jointly developed with the optical waveguide company, and the chip was jointly debugged with the original manufacturer for the first complete machine. The AR focus covers 0.5 meters to infinity; the acoustics uses self-developed dual speakers, the speakers are moved behind the ears, sound is guided through the air ducts inside the temples, and the rear sound cavity and sound leak hole are self-molded; the temple height is controlled at 3.7 mm, the front section is hollow and expanded to alleviate the chuck problem.
"Smart glasses must first be a pair of qualified glasses." Li Longzai believes that only when users are willing to wear and buy them can intelligence be implemented. But after the weight dropped to a certain level, he believed that the second half of the glasses was AI.
Qingmu hopes to make glasses into active assistants that can sense the scene the user is in, remember previous information, and determine when to proactively provide help. Based on this analysis, the AI capabilities are divided into three parts: the glasses side is used for perception, the mobile side is used for memory and orchestration, and the cloud side is only used for reasoning and does not hold data. It plans to rely on Tsinghua alumni resources to promote the development of AI Agent, starting with workplace scenarios such as meeting minutes collection.
Leifeng.com·Jingxi will continue to pay attention to the follow-up progress of the Qingmu figures. Welcome to add the author WeChat frenchfries0016 to communicate.
