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.

Charging system and method for electronic device controlled by audio output

A position detecting system and method for an electronic device used an audio signal input module of the electronic device and a signal receiver to connect to the audio signal input module convert an external position signal into an audio signal. A position detecting software running on the electronic device analyzes the audio signal. Accordingly, the current position of the electronic device is obtained. The audio signal input module of the electronic device is employed as an input port for the external position signal, thus saving the construction cost of the system. Besides, the current position of the electronic device with an ever-changing position can be obtained during a test process, such that the electronic device can start or stop a test item accordingly.
