A revolutionary sound experience! Xingji Meizu MYVU AR smart glasses introduce AAC's comprehensive acoustic solution

On November 30, MYVU all-weather fashionable AR smart glasses were officially released. The two new products, MYVU and MYVU Discovery, are equipped with AAC’s comprehensive AR software and hardware acoustic solutions. AR-specific super-linear speakers, customized sound cavity design, "far-field cancellation" acoustic algorithm, Golden Ears team tuning service, four major sound secret blessings, both internal and external, achieve an immersive listening experience with unbounded blending.

AAC Technologies AR-specific super-linear speakers, extremely thin and light, with excellent sound quality

In order to achieve the ultimate thin and light texture and experience, the MYVU team continues to explore cutting-edge technologies and continue to break through product processes. There are also stricter requirements for the selection of speakers arranged on the ultra-thin temples of the entire machine - they must be small in size and light in weight, and the sound quality must not be sacrificed. Therefore, MYVU AR smart glasses are positioned as "all-weather fashionable AR smart glasses"

AAC Technology’s AR-specific super linear speakers are currently the smallest super linear speakers in the industry. They have excellent performance and have become an excellent choice for Xingji Meizu MYVU and MYVU Discovery. In terms of thinness and lightness, it weighs as little as 1.45 grams and is only 3 mm thick. The rectangular design fits the temples perfectly, meeting the high requirements of Meizu MYVU and MYVU Discovery for lightness, comfort, fashion and beauty. In terms of performance, its amplitude can reach up to 0.5 mm and its resonance frequency is as low as 230 Hz, creating excellent high-fidelity sound quality, clear and balanced midrange, rich and powerful bass, and rich sound details

These two AR-specific super-linear speakers are located on both sides of the mirror to create "spatial range surround sound" for MYVU and MYVU Discovery. When users watch movies or play games at home, they can feel the unbounded blend of virtuality and reality. An immersive sound experience

Customized sound cavity design, open sound field to prevent sound leakage, exclusive private listening experience

How to protect user privacy under an open sound field design has always been an important challenge for AR glasses acoustic technology. AAC Technologies' AR-specific super-linear speakers adopt an innovative open sound field anti-leakage design. Through the unique layout of sound leakage holes and main sound holes, sound leakage can be greatly reduced. Compared with mainstream AR products on the market, low-frequency isolation is The sound level has been increased by nearly 10dB to ensure that sound only travels in the user’s ears. Even if users are in public places such as airplanes, high-speed trains, subways, etc., they can enjoy a private and moving listening experience without worrying about sound leakage and affecting others.

Xingji Meizu MYVU and MYVU Discovery are the first QQ Music "Premium Certified" AR glasses with panoramic sound. They are equipped with a "far-field silencing" acoustic algorithm jointly adjusted with AAC Technology to improve listening privacy. At the same time, it further optimizes the clarity and balance of the sound, making the sound quality more natural and transparent, and allowing the mid- and low-frequency sound effects to be better restored, and the sound effects to be richer and more realistic. According to AAC Acoustic Technology Acoustic Laboratory testing, its high-frequency performance has also been significantly improved, and its high-frequency performance is nearly 50% higher than that of mainstream AR products. When users go out with MYVU and MYVU Discovery, they can maintain an immersive audio experience at any time. After adjusting the audio, they can immediately enter a high-volume state. Even in a noisy environment, they can enjoy a refreshing outdoor entertainment experience.

In order to improve the low, mid and high frequency performance of Meizu MYVU and MYVU Discovery, improvements are needed

The "far-field silencing" acoustic algorithm jointly adjusted by both parties mainly includes the following contents: EQ correction frequency response: optimize the frequency response, improve the balance of the timbre and the restoration of the sound; DRC dynamic adjustment: optimize the sound dynamics, while retaining Maximize the impact of music while maximizing the original sound characteristics; Limiter protection: control signal amplitude to prevent high-frequency distortion; TDC transient correction: enhance sound intensity and fidelity; ViB bass enhancement: enhance low frequency, simulate bass

Golden Ears team’s tuning service and “sound coach” support ensure excellent sound quality

The AAC Golden Ears team conducted a comprehensive evaluation and detailed adjustments for the audio systems of Xingji Meizu MYVU and MYVU Discovery, focusing on the overall quality of the sound and crafting a more excellent sound effect: the human voice is clear and bright, It is rich in luster and has a natural and smooth overall listening experience, helping MYVU and MYVU Discovery pass the "Golden Ear" selection certification evaluation of the China Electronic Audio Industry Association.
