Abstract: An intellectual refrigerator combining with a portable electric device is present. The refrigerator has an image unit, a wireless transmitting unit and a micro control unit (MCU) therein. The image unit is used to monitor status or fetch image in a case of the refrigerator. The MCU electrically connects to the image unit and the wireless transmitting unit. The refrigerator further includes a connecting socket arranged on an outer surface of the case, and the connecting socket includes a first transmitting interface electrically connected to the MCU. When the electric device is plugged in the connecting socket, a connection is established by the MCU of the refrigerator with the electric device physically via the first connecting interface. When the electric device is removed from the connection socket, the connection is automatically turned to establish by the MCU with the electric device wirelessly via the wireless transmitting unit.

Abstract: A portable karaoke system, a karaoke method and an application program for the same are disclosed. The karaoke system comprises a receiving end karaoke apparatus and at least a transmitting end karaoke apparatus. The receiving end karaoke apparatus generates a song list to provide to the transmitting end karaoke apparatus according to songs internally saved and songs uploaded from transmitting end karaoke apparatus. The transmitting end karaoke apparatus transmits a selection command to receiving end karaoke apparatus for generating a play queue according to the song list. The receiving end karaoke apparatus plays the song files saved internally for generating music signals according to a play queue sequence. Lastly, the transmitting end karaoke apparatus receives external vocal signals and transmits the external vocal signals to the receiving end karaoke apparatus to perform audio mixing with the music signals.
