Description

These devices can not only bring music enjoyment to the driver and passengers during driving, but also provide real-time road information and support voice communication. In addition, the multimedia system can also work in conjunction with other functions of the vehicle (such as air conditioning adjustment, seat adjustment, etc.) to create a more intimate driving environment.

[0004] In the prior art, existing cars usually achieve internal monitoring by additionally setting up a mobile phone holder to install a mobile phone or additionally setting up a camera. However, setting up a mobile phone or a camera to achieve internal monitoring takes up more space in the car and is expensive. It is troublesome to export the captured content of the mobile phone and the camera. In addition, the shooting angle of the mobile phone is small and it needs to be constantly charged during the shooting process. In addition, the shaking of the vehicle during driving causes the picture taken by the mobile phone to be unclear.
