Abstract

Disclosed is a wireless charging mouse, comprising a wireless power receiving circuit, a wireless radiating circuit, a displacement detecting circuit and a control circuit. The control circuit is electrically connected to the wireless power receiving circuit, the wireless radiating circuit and the displacement detecting circuit. The wireless power receiving circuit wirelessly receives electromagnetic energy from a charging board. The displacement detecting circuit detects the displacement of the wireless charging mouse. The control circuit receives the electromagnetic energy from the wireless power receiving circuit, and outputs a displacement detecting signal to a wireless receiver through the wireless radiating circuit according to the detected displacement obtained from the displacement detecting circuit. When the electromagnetic energy received by the wireless charging mouse is less than a predetermined electromagnetic energy, the control circuit stops outputting the displacement detecting signal to the wireless receiver.
