smart audio glasses combine smart audio with the form of glasses, and configure an independent operating system for them, so that they have the functions of both, which not only enhance the portability of the product, but also have fashionable decoration functions, and are regarded as It is another market hotspot after TWS headsets.
In September 2019, Huawei and Korean fashion brand GENTLE MONSTER launched HUAWEI X GENTLE MONSTER Eyewear smart glasses officially launched. This series of glasses adheres to the design principles of simple fashion and smart core, focusing on product fashion And easy to wear. One year has passed since the release of HUAWEI X GENTLE MONSTER Eyewear II. Based on the previous work, the problem of sound leakage has been improved, and the charging, battery life, intelligent interaction and other aspects have been upgraded.
is also richer in appearance design, providing 4 sunglasses and 9 optical glasses, a total of 13 front frames, to meet the needs of different people in different scenarios. The charging box has also changed from a bag shape to a box shape, and adopts NFC wireless fast charging technology. Due to the size problem, the built-in battery of the charging box was cancelled. Correspondingly, the battery life of the glasses has been greatly improved, from 2.5 hours in the previous generation to 5 hours.
is configured with a 128mm² custom diaphragm, and a new inverse sound field acoustic system is added, which effectively reduces the sound leakage of the previous generation products, and can offset the sound leakage of up to 12dB; the latest Bluetooth 5.2 protocol further improves the connection stability; interactive experience Through the built-in vibration sensing, pressing sensing and sliding sensing three sensors, the control of various functions is realized.

IV. I love audio network summary
Huawei HUAWEI X GENTLE MONSTER Eyewear II smart glasses have little change in design compared to the previous generation products. The main change is that the glasses case is changed from a package shape to a box shape. The built-in battery of the charging box has been cancelled. Corresponding measures adopt NFC wireless fast charging technology to reduce charging time and improve the ability to quickly replenish power in a short period of time. The battery life of the glasses has also been greatly improved, the overall battery life has been doubled, and it can support 5 hours of battery life.
Other major changes are in the main control chip and speaker unit. The HUAWEI Eyewear II smart glasses are replaced by the previous BES Hengxuan 2300 Bluetooth audio SoC with the Huawei self-developed HiSilicon Hi1132 main control chip. The Bluetooth version has also been upgraded to 5.2. ; The speaker adopts a 128mm² custom diaphragm, and the inverse sound field acoustic system is blessed, which effectively reduces the sound leakage of Eyewear II and improves the wearing experience.
In the internal configuration, NXP NXP wireless charging IC is used on the motherboard of the glasses case, with a built-in drive tube; Aiwei AW9106B light control IC for RGB LED control; and nRF52832 Bluetooth BLE SOC.On the glasses, the internal structure of the left and right temples is mirrored, and the microphones are all located on the right leg; the lithium-ion battery has a capacity of 85mAh, from ATL New Energy Technology; the main control chip on the motherboard is Huawei’s self-developed HiSilicon Hi1132, which supports Bluetooth V5.2; and ET9562 single lithium battery linear charging chip, Shunxin ES7243 high-performance stereo audio analog-to-digital converter, Winbond Electronics Q64FWY low-voltage flash memory chip, etc.
