Description of the Invention: [Technical Field of the Invention] A consumer electronic product' particularly relates to an audio and video. The present invention relates to a device and a control method. [Prior Art] With the development of the electronics industry, audio and video products are becoming more diverse. = The functions of multiple products can cooperate with each other to report on multiple products. That is, their audio and video content can not only be provided to their own display: 2:8 can also be provided to other devices. This is in portable devices. The screen size of the portable device is limited, and the effect is one. When conditions permit, the user can output the video content of the portable device to a larger display and a better sound system. Other devices on the outside are watching video or listening to the frequency. Then its own audio and video display and playback is superfluous. Not only does 0 consume power, but after the display is turned off, the sound is still playing, and the user can only adjust the sound to a minimum or Mute, but these operations impose unnecessary operational burden on the user. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an audio and video device that is convenient to operate. It is also necessary to provide a corresponding control method for the audio and video device. The audio and video device comprises: a playing unit for playing audio and video data and outputting video signals and audio signals; 7 200930048 " 蔡员〒 go a /, yuan ' is used to display video content according to the video signal; 夕 ' is used to play audio content according to the audio signal; the first switch is used to generate a first closing command in response to user operation, round out - ^ » _ ^ ^疋, which is the audio and video interface, used for the output of the video signal and the sound bottle, and the video signal and audio generated by the early 7^ playback will be played. Provided to the external device for use; Header:: early when used in the output unit has an external device connection, the - close command to close the display unit and the output of the thorn eight; in the early morning: When there is no external device connection, 'in response to the first-off command, the output of the speaker is turned off, and the output of the speaker is kept. An audio and video device control method includes the following steps: playing audio/video data and displaying images and playing Sound; receiving the first close command; detecting whether there is an external device connected to the audio and video interface of the audio and video device, and if there is an external device connected to the audio and video interface of the audio and video device, The closing command turns off the display of the image and the output of the sound, and if the device is connected to the audio and video interface of the audio and video device, the output of the image is kept in response to the first closing command to keep the output of the sound. And the control method thereof, when the user can display and play the audio and video content on the audio and video device by using the external device, the user can simultaneously turn off the output of the image and the output of the sound, which is convenient to operate and achieve the purpose of saving electricity. 8 200930048 ιμΊ Ί 其 — — — — 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 较佳 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该The audio and video device 10 is provided with a unit 102, a display unit 1〇4, a speaker 1〇6, a first switch 1〇8Α, a first switch, a switch 1〇8Β, an output unit 110, and a control unit 112. The play early 102 is used to play audio and video data and output video signals and audio signals.显 Not only 兀1〇4 is used to display video content according to the video signal. The rabid 106 is used to play the audio content according to the audio signal. The karaoke 108 is such that the integrated speaker can also be a worn earphone. The first switch ι〇8Α is used to generate a first close command in response to a user operation. The second switch 108 is operative to generate a second close command in response to a user operation. Such as the ^ switch position and the second switch! The surface can be a push button switch or a touch switch. The output unit το 110 is an audio and video interface for outputting the video signal and the audio signal to provide the visual (4-) number and audio signal generated by the playback unit 1〇2 to the external device for use. The control unit 112 is configured to control whether the display unit and the taste unit have an output according to whether the output unit has a connection of an external device, and the first off command and the second switch command. The control unit 112 includes a detection module 122 and a switch module 124. The detecting module 122 is configured to detect whether there is an external device connection on the output unit U0, that is, whether there is an audio/video output request, and a status signal is generated. The switch module 124 is configured to control the display unit 9 200930048 104 and the slave according to the first off command, the second switch command, and the status signal. The closing action of eight 106. When the device is connected, if the first level 0aa is received, 2 is detected, and the mm-00 close command is issued, the switch module 124 turns off the switch of the first and second times. If the detection module 122 does not check the window 丨H out 'holds ^8 104 to close the output of the display unit 102;:: when the command 'switch module ^ blade is smashed, The output of the horn 100 is maintained.立 立颜=In the use of external devices to display and play the audio and video device 10, the two usually do not require the display of the audio and video device 1 itself to close the door so the user can simultaneously and also 4 and ^8 by the first switch 108A. The output of 106 is not only easy to operate, but also achieves the purpose of power saving. In addition, when you want to turn off the display, you can _ 2 1 2: In the case, you only need to hold the T in various situations... The output of 4 is satisfied. Please refer to Figure 2, and the 苴 is in the tooth f, 丨 ' The flow chart of the control method of the audio and video device of the preferred real target mode comprises the following steps: Step S21, playing the audio/video material and displaying the image and playing the sound. The user's 2^23' receives the close command'. The close command may be generated based on the user's button operation. In step S25, the type of the closing instruction is detected. If it is the first instruction, the process proceeds to step S27, and if it is the second command, the process proceeds to step (3). (4) 2 S27' detects whether there is an external device and the audio and video of the audio and video device, ', and if so, proceeds to step S29, and if not, proceeds to step S31. 200930048 Step S29, the display of the image and the rotation of the image are ended, and the flow ends. For example, if the rotation of the image is turned off, the flow is controlled by the above-mentioned audio and video vibration control method, and the user can select the same when using the external device to play the audio and video content on the audio and video device. ^ Close the display of its own image display and sound, you can also choose to only turn off the image, do not maintain the output of the sound, to meet the various needs of users. It is to be understood by those skilled in the art that the above-described embodiments are merely illustrative of the invention and are not to be construed as limiting the invention as set forth in the <RTIgt; Appropriate changes and changes are within the scope of this issue.
