Specifically, the camera lens 400 is arranged on the antenna assembly on the camera decorative ring 200, and can be fixed on the antenna assembly by a fixing method such as double-sided tape or glue. The camera lens 400 can play the role of protection and light transmission, so as to ensure The light in the external environment of the electronic device can enter the electronic device through the camera lens 400, and at the same time, dust in the external environment can be prevented from falling on the camera, which affects the shooting resolution of the camera.

In the embodiment of the present application, the camera module includes an antenna assembly, and the antenna assembly includes an antenna coil 310. The antenna coil 310 is used to convert external radio waves into high-frequency current and transmit it to the input end of the electronic device, or to convert the The high-frequency current is transmitted to the transmitting antenna and radiated, thereby realizing data interaction between electronic equipment and other terminal equipment.

The camera decorative ring 200 is arranged opposite to the camera. Specifically, the space and thickness of the convex hull of the camera decorative ring 200 can be used to set the antenna coil 310 on the camera decorative ring 200, so as to realize that the antenna coil 310 is based on the camera decorative ring 200 Make settings. Specifically, the antenna coil 310 can be arranged outside the camera decorative ring 200 or inside the camera decorative ring 200, which is beneficial to make the structure more compact and reduce the problem of large thickness caused by arranging the antenna components separately, thereby reducing the camera The thickness of the module in the shooting direction of the camera makes the electronic device lighter and thinner, thereby solving the problem of the large thickness of the electronic device.

The camera module disclosed in the embodiment of the present application improves the structure of the camera module in the related art, and the antenna coil 310 is arranged on the camera decorative ring 200. Specifically, the antenna coil 310 can be arranged outside the camera decorative ring 200. Or set in the camera decorative ring 200, so that the distance between the antenna coil 310 and the camera decorative ring 200 is reduced, and then the thickness of the camera module in the camera shooting direction can be reduced, so that the thickness of the electronic device is lighter and thinner. The camera module disclosed in the embodiments of the present application can solve the problem of the large thickness of the entire electronic device.

At the same time, the antenna coil 310 is disposed on the camera decorative ring 200, thereby making the entire antenna assembly closer to the camera decorative ring 200, making the space near the main board more concentrated, thereby avoiding affecting the layout of other electronic devices on the main board , which is beneficial to improve the utilization rate of the internal space of electronic equipment.
