Patent ID: 8655417

Claim:
A television with a wireless audio signal transmission function, comprising: a headset place slot, used for containing and electrically coupling a wireless headset, determining whether or not the wireless headset is in connection with the headset place slot, and transmitting an electric potential signal; wherein the wireless headset includes a chargeable battery and a charging circuit used for receiving electric power to charge the battery; an audio processing module used for outputting an internal audio signal; a system audio interface, coupled to a speaker, used for outputting the internal audio signal through the speaker upon a receipt of the internal audio signal; and a wireless audio signal transmission module, comprising: a control unit capable of communicating with the wireless headset via a wireless connection and outputting the internal audio signal to the wireless headset; an audio signal switching unit, selectively coupled with the system audio interface and the control unit depending on a voltage level of the electric potential signal outputted to the internal audio signal switching unit, used for receiving the internal audio signal, and determining whether or not to output the received internal audio signal to the system audio interface or the control unit; a connecting interface, coupled to the headset place slot, used for transmitting the electric potential signal to the internal audio signal switching unit; and a power supply circuit, coupled to the connecting interface, used for providing electric power to charge the battery of wireless headset through the charging circuit when the wireless headset is placed into the headset place slot and electrically connected with the connecting interface via charging contacts; wherein: when the electric potential signal is a high electric potential signal, indicating the wireless headset is placed into the headset place slot, the audio signal switching unit is coupled to the system audio interface before outputting the internal audio signal to the system audio interface; when the electric potential signal is a low electric potential signal indicating the wireless headset is not placed into the headset place slot, the audio signal switching unit is coupled to the control unit before outputting the internal audio signal to the control unit; wherein the wireless headset is used to receive the internal audio signal transmitted from the control unit and at least one external audio signal transmitted from an external device, and the wireless headset outputs the external audio signal while skipping the internal audio signal at the time of receiving the internal audio signal and the external audio signal substantially simultaneously.
