[0061] Figure 3 It is a schematic diagram of the circuit board 5 provided by the embodiments of the present disclosure. In some embodiments of the present disclosure, as Figure 3 shown, the bottom surface 51 and the top surface 52 of the circuit board 5 are flat surfaces, and both the bottom surface 51 and the top surface 52 are parallel to the extension direction of the first side frame 111. The bottom surface 51 is located on the side close to the first side frame 111, and the top surface 42 is located on the side close to the second side frame 112.

[0062] In some embodiments of the present disclosure, copper plating areas are provided on the bottom surface 51 and the top surface 52 of the circuit board 5, and the copper plating areas are opposite to the first antenna 4. Specifically, the copper plating area is opposite to the third feeding point 42 of the first antenna 4 to couple and feed the first antenna 4. The bottom surface 51 and the top surface 52 are two surfaces on the circuit board 5 for arranging components. Both the bottom surface 51 and the top surface 52 are perpendicular to the plane where the bracket 12 of the electronic device is located, that is, the thickness direction of the circuit board 5 is perpendicular to the thickness direction of the bracket 12, thereby reducing the space occupied by arranging the circuit board 5, enabling the battery compartment 2 of the electronic device to have a larger arrangement space, and being able to increase the battery capacity of the electronic device by 200 mAh - 400 mAh to increase the available usage time of the electronic device.

[0068] In some embodiments of the present disclosure, refer to Figure 3, in the direction perpendicular to the top surface 52 of the circuit board 5, the height of the wire clip 10 is not greater than the height of the grounding spring piece 7. Specifically, the heights of the wire clip 10, the cable 9, the cable socket 8, and the grounding spring piece 7 protruding relative to the top surface 52 are approximately the same, all not higher than 1 mm. This layout structure reduces the layout space of the circuit board 5, enables the battery compartment 2 of the electronic device to have a larger layout space, and is beneficial to increasing the battery capacity of the electronic device.
