Detailed Description
The invention provides an audio playing method and system of a mobile terminal. In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The present invention provides an audio playing method of a mobile terminal, referring to fig. 1, the audio playing method of the mobile terminal includes the following steps:
s100, when at least two videos are played on a mobile terminal interface, detecting the triggering of each video;
and S200, according to the trigger, using the audio signal of the triggered video as an audio output signal of the mobile terminal.
The above steps are described in detail with reference to specific examples.
In practical application, the mobile terminal of the invention can be a mobile phone, a tablet computer, a handheld terminal and the like. When the mobile terminal plays two or more videos on the same interface, one of the videos is selected, and the audio output of the video is set to be audio priority output. Preferably, the audio output of other videos of the interface is in a waiting state. When another video is selected, the audio output is switched to the audio-priority output of the video. That is, when the mobile terminal plays two or more videos on the same interface, one of the videos a is selected, and the audio output of the video a is set as the audio priority output. When another video b is selected, the audio output is switched to the audio-priority output of the video b.
Preferably, the step S200 specifically includes:
s210, when the video triggering operation is detected, setting the triggered video as a first video, and switching the audio output signal of the mobile terminal into the audio signal of the first video.
Specifically, when the mobile terminal opens two or more videos, an audio detection module may be disposed in the mobile terminal, and the audio detection module detects that a human hand touches the opened videos, such as the first video a, and the audio of the first video a is preferentially output. The audio detection module senses an audio signal output by opening the first video a according to the opened video touched by a human hand, and the audio signal reflects whether the audio of the video played by the mobile terminal is preferentially output or not. When the audio detection module detects that the first video a played by the mobile terminal has audio signal output, the audio of the first video a is preferentially output. When the audio detection module detects that the second video b played by the mobile terminal has audio signal output, the second audio b of the video is preferentially output.
Preferably, the step S200 further includes:
and S230, adjusting the audio signal of the video which is not triggered to be in a waiting output state.
Specifically, the description will be given by taking an example in which the interface of the mobile terminal opens two videos, i.e., a first video a and a second video b. When the audio detection module detects that the audio signal output exists in the first video a played by the mobile terminal, the audio of the first video a is output preferentially, and the audio of the second video b is output in a waiting mode. Otherwise, when the audio detection module detects that the second video b played by the mobile terminal has an audio signal output, the audio of the second video b is output preferentially, and the audio of the first video a is output in a waiting mode.
In practical application, an audio control module is arranged in the mobile terminal and controls the audio output state of the video played by the mobile terminal, namely the audio control module controls the audio priority output state and the audio waiting output state of the video played by the mobile terminal, and the audio control module controls the audio output of the video opened by the mobile terminal. When the audio detection module detects that the audio of the video played by the mobile terminal is in a priority output state, namely the audio detection module detects the audio signal output when the video is played, the audio signal in the audio control module controls the output unit to preferentially output the audio signal of the video selected by the human hand according to the priority of audio output.
When a human hand touches the first video a, the audio signal sensing unit in the audio detection module senses the audio signal output by opening the first video a. The audio control module sends an audio priority output request signal to the central processing unit to request the central processing unit to control the operation of the audio signal control output unit in the central processing unit. The central processing unit calls a first audio enabling signal instruction in an internal memory unit of the central processing unit and outputs a first audio enabling signal. Through the first GPIO output end of the central processing unit, the first audio enable signal is output to the audio signal control output unit, and the audio signal control output unit is opened. And the audio signal of the first video a controls the output unit to output through the audio signal.
Preferably, after the step S210, the method further includes:
and S220, when the video triggering operation is detected again, setting the triggered video as a second video, and switching the audio output signal of the mobile terminal into the audio signal of the second video.
Specifically, when the user is detected to trigger the video again, the audio output signal of the mobile terminal is switched to the audio signal of the video which is triggered again.
In practical application, when the audio detection module detects that the second video b outputs the audio signal, an audio output switching module is arranged in the mobile terminal, and the audio output switching module cuts off the audio signal of the first video a and switches the audio signal to the audio signal of the second video b for output. When the audio detection module detects that the second video b outputs an audio signal, the audio detection module sends a level driving signal to the audio output switching module to drive the audio output switching module to work.
And the audio output switching module sends an audio switching request signal to a central processing unit to request the central processing unit to control the audio switching of the first video a and the second video b. The central processing unit calls an audio switching instruction and outputs an audio switching signal to the audio output switching module. The audio switching signal is used as a blocking signal of an audio signal to cut off the audio output of the first video a. The audio-priority output is switched from the first video a to the second video b, and the audio signal of the second video b is output preferentially. Similarly, the central processing unit calls a second audio enable signal instruction at an internal memory unit of the central processing unit, the second audio enable signal is output to the audio signal control output unit through a second GPIO output end of the central processing unit, and the audio signal control output unit is opened. And the audio signal of the second video b controls the output unit to output through the audio signal.
Preferably, the step S220 specifically includes:
s221, when the video triggering operation is detected again, setting the triggered video as a second video, and judging whether the second video and the first video are the same video;
s222, when the second video and the first video are the same video, the audio output signal of the mobile terminal is not switched; and when the second video and the first video are not the same video, switching the audio output signal of the mobile terminal into the audio signal of the second video.
Specifically, when the user is detected to have the operation of triggering the video again, whether the second video triggered again is the same as the first video or not is judged, and if the second video triggered again is the same as the first video, the audio output is not switched; if not, the audio output of the mobile terminal is switched to the audio signal of the second video triggered by the user again.
Based on the audio playing method of the mobile terminal provided by the embodiment, the invention also provides an audio playing system of the mobile terminal. Referring to fig. 2, the audio playing system of the mobile terminal includes:
the trigger detection module 10 is used for detecting the trigger of each video when at least two videos are played on the interface of the mobile terminal;
and the audio switching module 20 is configured to use the audio signal of the triggered video as an audio output signal of the mobile terminal according to the trigger.
Further, the audio switching module 20 includes:

Further, the audio playing system of the mobile terminal further includes:
