1. A mouse pad, adapted to a wireless charging transmitter and operating in cooperation with a wireless mouse, the mouse pad comprising:
a main body;
a primary resonant coil circuit;
a wireless charging transmission control circuit electrically connected to the primary resonant coil circuit;
a secondary resonant coil circuit; and
a port electrically connected to the wireless charging transmission control circuit;
wherein the wireless charging transmission control circuit is electrically connected to a power conversion circuit through the port, and the power conversion circuit provides a working voltage for the primary resonant coil circuit;
wherein the wireless charging transmission control circuit, the primary resonant coil circuit, and the secondary resonant coil circuit are arranged inside the main body, the secondary resonant coil circuit and the primary resonant coil circuit are not wiredly connected to each other, and the secondary resonant coil circuit and the wireless charging transmission control circuit are not wiredly connected to each other;
wherein the secondary resonant coil circuit wirelessly receives a first electromagnetic energy provided by the primary resonant coil circuit through magnetic resonance, and then converts the first electromagnetic energy into a working power for the secondary resonant coil circuit;
wherein the secondary resonant coil circuit relays the working power, the secondary resonant coil circuit converts the working power into a second electromagnetic energy, and then wirelessly outputs the second electromagnetic energy to the wireless mouse through magnetic resonance.
