A wireless mouse includes a magnetic ball, a power generating device and a power storage device. The power generating device includes an inductive coil, being dome-shaped and partially covering the magnetic ball and configured for generating inductive voltage following the movement of the magnetic ball, and a converting unit, being configured for converting the inductive voltage to a stabilized DC voltage. The power storage device electrically is coupled to the power generating device and configured for being charged by the converting unit using the stabilized DC voltage and provide power for the wireless mouse. |
