Electro-magnetic induction type self-energy-storage wireless mouse

The utility model discloses an electro-magnetic induction type self-energy-storage wireless mouse and relates to a mouse. The electro-magnetic induction type self-energy-storage wireless mouse comprises a mouse body, a mouse control module, a power supply module, a data coding module, a wireless sending module, a wireless receiving module and a data decoding module. The power supply module comprises a permanent magnet, a circular track with a sliding groove, sliding pieces, a coil and charging batteries. The two ends of the permanent magnet are fixed at the lower portions of the circular track through the sliding pieces which can move along the circular track. The coil is horizontally fixed on the outer periphery of the circular track. The two ends of the coil are connected into the charging batteries. When the mouse moves, the sliding pieces slide in the circular track under the effect of inertia, so that the magnetic flux of the permanent magnet in the coil is changed, induced electromotive force is generat
