This Bone Conduction Headphone was created for a third year class.

We often see cyclists cycling around the city with headphones on. But in the complex environment of city, cycling itself has certain danger.
Wearing headphones to eliminate your auditory perception will put you at risk.
And the feeling of being closed makes it impossible for the rider to perceive the danger behind him.
Design a headset that not only meets the needs of everyday music listion, but also can be used while cycling.
Traditional headphones: normal music listening (HQ voice export, comfortable, no sound leakage)
Bone conduction headphone: sports use (safety, no stuffiness)
Upload AR glasses to check the weather, map and time on the Internet.
