Abstract:
This charging device comprises: a battery that stores electricity, and supplies electricity to an earphone; and a thermoelectric power generation element connected to the battery. The thermoelectric power generation element comprises a thermoelectric power generation element that has a high temperature part and a low temperature part, and generates thermo-electromotive force when there is a difference between the temperature of the high temperature part and the temperature of the low temperature part. Thus, it is possible to charge the battery installed without being connected to a power source.
