| 摘要 |
The present invention relates to a magnetic induction charging device (50) including an electric power supply source (60) connected to a main coil (61). The device (50) comprises manual resonant circuits (70, 80, 90, 100) having different resonance frequencies within a range of a predetermined main frequency value. The manual resonant circuits (70, 80, 90, 100) include secondary coils (71, 81, 91, 101), respectively. The secondary coils (71, 81, 91, 101) are arranged different areas of the main coil (61). The electric power supply source (60) is adaptive to generate different charge signals of a main frequency within a range of the predetermined main frequency value. |
