The voltage regulator is composed of 123. The plurality of capacitors are connected in parallel to improve the waveform of the DC voltage, generate an ideal DC voltage, and improve charging efficiency. [0010] The induction coil 121 is made of a conductive material. In a preferred embodiment, the induction coil 121 and the antenna 11 are made of the same material, so that the induction coil 121 and the antenna 11 have the same transmission and reception frequency.
