US 2016/0365751 A1 · POWER SOURCE DEVICE FOR PORTABLE APPARATUS, PORTABLE APPARATUS, AND CHARGING DEVICE

Abstract

A power source device for a portable apparatus has a secondary battery, a circuit board, and an electricity reception module. At the circuit board is mounted a charging/discharging circuit containing a charging circuit for charging the secondary battery by the input of external power. The electricity reception module has a power extraction coil and an electricity receiving resonance coil to which power is supplied from outside by the resonance phenomenon and then output as external power to the charging circuit. A portion or all of the circuit board and/or secondary battery is disposed at the inside of the power extraction coil and electricity receiving resonance coil of the electricity reception module.
