On November 30, the MYVU all-weather fashion AR smart glasses were released, featuring AAC Technologies’ comprehensive AR software and hardware acoustic solution. The two new products, MYVU and MYVU Discovery, are equipped with dedicated SLS super linear speakers, customized sound chamber design, a Far-field Sound Leakage Cancellation acoustic algorithm, and professional tuning performed by the Golden Ear team. These four keys to extraordinary sound achieve an immersive auditory experience that blends seamlessly with the surroundings.
AAC Technologies’ AR-Dedicated SLS: Ultra-Slim and Exceptional Sound Quality
MYVU AR is positioned as all-weather fashion AR smart glasses. The MYVU AR smart glasses team relentlessly explored cutting-edge technologies and continuously pushed the boundaries of product craftsmanship to achieve an ultra-slim build and exceptional user experience. The team imposed stricter requirements on the speakers located in the thin frame of the glasses: compact size, lightweight, without compromising audio quality.
AAC Technologies’ AR-dedicated SLS super linear speakers, currently the industry’s smallest, combine high-performance capabilities, making them an excellent choice for MYVU and MYVU Discovery. The SLS is as light as 1.45g and as thin as 3mm. The rectangular design perfectly fits the frame, meeting the high demands of Meizu MYVU and MYVU Discovery for light weight, comfort, and stylish appeal. In terms of performance, the SLS has a maximum excursion of 0.5mm and a low resonance frequency of 230Hz, creating incredible high-fidelity sound quality with clear and balanced mid-range, powerful bass, and rich reproduction of sound details.
Furthermore, the two AR-dedicated SLS super linear speakers symmetrically positioned on both sides of the glasses create a Spatial Sound for MYVU and MYVU Discovery. When users are at home watching movies or playing games, they can experience an immersive sound that seamlessly blends virtuality and reality.
Customized Sound Chamber Design Ensures an Open Soundstage with Minimal Sound Leakage, Providing an Exclusive and Private Listening Experience
Protecting users privacy while maintaining an open soundstage has always been a significant challenge in the acoustic technology of AR glasses. AAC Technologies’ AR-dedicated SLS super linear speakers utilize an innovative design for an open soundstage with minimal sound leakage. With a unique layout of the vent holes and main sound outlet, sound leakage is significantly reduced. Compared to mainstream AR products on the market, the low-frequency isolation is improved by nearly 10dB, ensuring that sound is only transmitted to the user’s ears. Even when users are in public places such as airplanes, high-speed trains, or subways, they can enjoy both private and captivating listening experiences without worrying about sound leakage.
Far-field Sound Leakage Cancellation Acoustic Algorithm Enhances Sound Quality
Xingji Meizu MYVU and MYVU Discovery are the first AR glasses to receive the QQ Music Premium Certification for panoramic sound output. By incorporating the Far-field Sound Leakage Cancellation acoustic algorithm developed in collaboration with AAC Technologies, these glasses not only enhance privacy during listening but also optimize clarity and balance, delivering more natural and transparent sound. The algorithm also provides better reproduction of mid- and low-frequency audio, creating a more immersive and realistic sound experience. According to acoustic testing conducted in the AAC Technologies Acoustic Laboratory, the high-frequency performance of MYVU and MYVU Discovery has significantly improved, with a nearly 50% enhancement compared to mainstream AR products. Users can enjoy an immersive audio experience at any time while wearing MYVU and MYVU Discovery outside. The volume of the glasses instantly increases in loud environments for users to continue enjoying their entertainment. This provides a pleasant and enjoyable outdoor experience.

Enhancing Meizu MYVU and MYVU Discovery with improved performance in the low-, mid-, and high-frequency ranges.
The jointly calibrated Far-field Sound Leakage Cancellation acoustic algorithm includes the following main features.
●Frequency response correction with an equalizer: Optimize the frequency response to improve tonal balance and sound fidelity;
●Dynamic range control (DRC): Improve sound dynamics, retain original sound characteristics, and enhance the impact of sound;
●Limiter protection: Control signal amplitude to prevent high-frequency distortion;
●Transient dynamic correction (TDC): Enhance sound dynamics to improve fidelity;
●Virtual bass enhancement(ViB): Enhance low frequencies based on psychoacoustic model.
