BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. 1 is a flow chart of a method for playing an audio and video file according to an embodiment of the present invention. As shown in FIG. 1 , the audio and video file playing method mainly includes the following processing: Step S102: The terminal acquires its current placement angle; wherein, the placement angle refers to an angle of an angle between a plane where the terminal displays the screen and a horizontal plane. Step S104: When the current placement angle meets the predetermined condition, the terminal determines to trigger the video closing operation, close the video file currently being played, and keep the audio file playing. In the related art, a terminal (for example, a mobile phone) consumes a large amount of power when using a multimedia function, such as watching a movie, a television, or the like. In order to save power, the above method is adopted, since the automatic closing operation can be performed on the video file in the audio and video file being played, thereby avoiding unnecessary consumption of power, thereby achieving energy saving. The predetermined condition may include, but is not limited to, one of the following: the placement angle is 0° (ie, the screen of the terminal is parallel to the horizontal plane), and the placement angle is 90° (ie, the plane of the screen of the terminal is perpendicular to the horizontal plane). When the user needs to view the video file, the probability that the screen of the terminal is parallel to the horizontal plane or the plane of the screen of the terminal is perpendicular to the horizontal plane is not high. When the mobile phone is in these two states, the above scheme is adopted, the video file currently being played is closed, and the audio file is played, which can effectively save power. In a preferred implementation process, the terminal can obtain the current placement angle by using the sensing device. When the current placement angle meets the predetermined condition, the terminal determines to trigger the video shutdown operation to close the video file in the currently playing audio and video file. Similarly, the terminal can also change the placement angle through the sensing device, so that the terminal switches to the power saving mode when certain conditions are met. It should be understood that the sensing device herein may be any hardware module or device that can be used to implement the above functions, such as a horizontal or gravity acceleration sensor. For specific applications, the terminal may preset and save the above predetermined conditions for triggering the video shutdown operation. Specifically, the terminal may set the foregoing predetermined condition and save it in response to the user operation, and the predetermined condition may be set by the mobile phone manufacturer and saved in the mobile phone. Preferably, before the step S102 is performed, the following processing may be further included: (1) the terminal determines that the placement angle thereof changes;

(2) The terminal determines to switch from the non-power saving mode to the power saving mode after the predetermined angle of the change is maintained for a predetermined time. In the preferred implementation process, the power-saving mode can also be turned on as a sufficient condition for implementing the audio-video file playback solution, that is, when the terminal is in the power-saving mode, when the placement angle of the terminal satisfies the predetermined condition, the present invention can be implemented. The above audio and video file playback scheme provided by the invention. When the terminal is in the non-power saving mode, the above-mentioned audio and video file playing scheme provided by the present invention cannot be implemented regardless of whether the current placement angle of the terminal satisfies the above predetermined condition. Preferably, in step S104, after the video file is closed, the foregoing method may further include: processing, when the placement angle of the terminal changes and the placement angle of the terminal does not satisfy the predetermined condition, determining that the triggering of the video playback is resumed. Operate, and keep the audio and video files in sync. For example, when the placement angle of the terminal is set to 0° (that is, the face of the terminal is parallel to the horizontal plane), the video file is closed. When the placement angle of the terminal is changed from 0° to 30°, the video file is resumed. And synchronized with the audio file, this makes the embodiment of the present invention more practical and user-friendly. In the specific implementation process, the terminal needs to first read the current time point of the audio file, and then restore the video file to the playback frame corresponding to the time point, so as to synchronize the audio and video files. 2 is a flow chart showing a method for playing an audio and video file according to a preferred embodiment of the present invention. Here, the terminal is a mobile phone and the video off operation is triggered when the mobile phone is placed at an angle of 0° as an example. As shown in FIG. 2, the audio and video file playing method mainly includes the following processing: Step S202: When the terminal plays the audio and video file, it is determined that the placement angle of the terminal changes. In step S204, it is determined whether the changed placement angle is maintained for a predetermined time. If yes, go to step S206; otherwise, go to step S218. Step S206, the terminal enters a power saving mode. In a preferred implementation process, when the terminal determines that the placement angle thereof changes, and the changed placement angle is maintained for a predetermined time (where the predetermined time can be set according to the user's needs, it may be 2 seconds, 5 seconds, 10 seconds, etc. When the terminal automatically switches from the non-power saving mode to the power saving mode. Thereafter, when the terminal is in the above power saving mode, when the placement angle satisfies the above predetermined condition, the closing operation of the video file currently playing the audio and video file may be triggered. Of course, in the specific implementation process, the user can also manually switch to the power saving mode. For example, a software or hardware button can be set to trigger entry into the power save mode. Step S208, obtaining a current placement angle size of the terminal. In step S210, it is determined whether the placement angle is 0°. If yes, go to step S212; otherwise, go to step S218. It should be noted that in the present embodiment, the above predetermined condition is: the placement angle is 0° (may also be regarded as 180°). If the above predetermined condition is set to: The placement angle is 90°, it is necessary to determine whether the screen of the screen of the mobile phone is at an angle of 90° to the horizontal plane. Step S212, the video file being played is closed and the audio is played normally. In a specific application, the backlight of the mobile phone can be activated. When the predetermined time is reached, the backlight of the mobile phone is turned off to save power. The technology for turning off the backlight can be implemented by related technologies, and details are not described herein. In step S214, when the placement angle of the mobile phone changes, the process proceeds to step S216. When the placement angle of the mobile phone changes again, the placement angle of the mobile phone is no longer maintained at 0°, that is, the above predetermined condition is not satisfied, and the playback of the video file can be resumed at this time. In step S216, the video file resumes playing and the audio and video are synchronized. It can be seen from step S214 and step S216 that the user only needs to move the mobile phone, change the placement angle of the mobile phone to trigger the video recovery operation, resume the playback of the video file, and ensure the audio and video synchronization. The audio and video synchronization is ensured here, which can be implemented by the technical solutions in the related art, and will not be described here. In summary, the core idea of the present invention is to set the power saving mode of the terminal. In this mode, according to the user setting the predetermined condition, the placement angle is 0°, for example, when playing the video, if the mobile phone is judged to be After the placement angle is 0° seconds, the terminal automatically closes the video file of the currently playing content, and only retains the audio file, so that the user does not affect the audio portion, and the power consumption of the mobile phone can be saved. Of course, if the user needs to view the video all the time and select the normal mode of video playback, the mobile phone can always be in the normal playing state. The method realizes a power-saving operation mode while satisfying the user's entertainment demand, and is very energy-saving and humanized.

When the audio and video files are used, when the audio and video files are not required, the terminal placement angle triggers the video shutdown operation to close the video file, and the audio file is normally played, thereby reducing the power consumption of the terminal. , and thus achieve energy saving effects. Preferably, as shown in FIG. 4, the terminal may further include: a sensing unit 36 configured to sense whether a placement angle of the terminal changes; in a preferred implementation, the sensing unit 36 may be a horizontal sensor or a vertical acceleration sensor. Wait. In a preferred implementation process, the control unit 32 is further configured to determine to switch the terminal from the non-power saving mode to the power saving mode after the changed placement angle is maintained for a predetermined time. In the above power saving mode, when the terminal satisfies the placement angle to maintain the predetermined condition, the closing operation of the video file currently being played in the audio and video file may be triggered. Preferably, the predetermined condition includes one of the following: a placement angle of 0° and a placement angle of 90°.
