Patent ID: 8831250

Claim:
An electronic device adapted to play audio signals, the electronic device comprising: a first output module adapted to generate a first audio signal; a second output module adapted to output second audio signals with different channel; a play module adapted to play the first audio signal; a judgment module adapted to determine whether the first audio signal is generated and generate a control signal, if the first audio signal is generated, the judgment module generates a first control signal; a first switch module adapted to switch into a first state for transmitting the first audio signal to the play module according to the first control signal; and a second switch module adapted to select one of the second audio signals and transmit the select second audio signal to the first switch module; wherein when the first audio signal is not generated, the judgment module generates a second control signal to control the first switch module to switch into a second state for transmitting the selected audio signals to the play module, and the play module further plays the selected second audio signal.
