ABSTRACT:
A charging system and method for an electronic device controlled by audio output are used for controlling an external charging power supply to charge the electronic device. An electric quantity detection software runs on the electronic device, for detecting an electric quantity of the electronic device and generating audio signals indicating a message of performing a charging operation or a message of stopping the charging operation. An audio output interface is disposed on the electronic device for outputting the audio signals. A decoding device is connected to the audio output interface for receiving the audio signal and controlling the external charging power supply to perform the charging operation or to stop the charging operation on the electronic device. The charging system and method for the electronic device can effectively control the electric quantity of the electronic device, without requiring any charging control circuits.
