Problems solved by technology

At present, mobile terminals also have dual speakers. When a mobile terminal with dual speakers is used as the receiving end of screen projection, it generally uses the preset single speaker or dual speakers to play by default. If dual speakers are used to play, if the user does not need stereo, the power consumption of the mobile terminal will be increased

Embodiment 1

[0077] Since the existing dual-speaker mobile terminal is used as a screen projection, the projected sound is played in a single mode, and the user experience is poor. Embodiments of the present invention provide a method for controlling speaker playback, which can intelligently select speakers for playback, such as Figure 7 As shown, the method of the present embodiment includes the following steps:

[0078] Step 701, after the mobile terminal receives the video stream, identify the screen mode of the video stream, if the screen mode of the identified video stream is landscape mode, go to step 702, if the screen mode of the identified video stream is vertical screen mode, go to step 703;

[0079] Step 702, if it is identified that the screen mode of the video stream is a landscape mode, then use the first speaker and the second speaker to play the audio of the video stream at the same time;

[0080] Step 703: If it is identified that the screen mode of the video stream is a...

Embodiment 2

[0084] Figure 8 It is a flowchart of a method for controlling speaker playback according to an embodiment of the present invention, such as Figure 8 As shown, the method of the present embodiment includes:

[0085] Step 801. After receiving the video stream, the mobile terminal identifies the screen mode of the video stream;

[0086] Step 802, if it is identified that the screen mode of the video stream is landscape mode, then go to step 803; if it is identified that the screen mode of the video stream is portrait mode, then go to step 805;

[0087] In this embodiment, if the aspect ratio of the screen of the video stream is 16:9 or 4:3, it is recognized that the screen mode of the video stream is landscape mode; for example, the aspect ratio of the screen of the video stream is 9:16 or 3:4, then it is identified that the screen mode of the video stream is a vertical screen mode.

[0088] Step 803, the mobile terminal uses the first speaker and the second speaker to simul...

Embodiment 3

[0096] Figure 9 It is a schematic diagram of a mobile terminal according to an embodiment of the present invention, such as Figure 9 As shown, the mobile terminal 900 of this embodiment has dual speakers, and also includes:

[0097] The identification module 901 is configured to identify the screen mode of the video stream after receiving the video stream, and notify the control module 902 of the identification result;

[0098] The control module 902 is configured to control playing with two speakers or playing with a single speaker according to the screen mode of the video stream identified by the identification module. If it is identified that the screen mode of the video stream is a landscape mode, the audio of the video stream is played simultaneously by using the first speaker and the second speaker; if the screen mode of the video stream is identified as a vertical screen mode, Then use one of the first speaker and the second speaker to play the audio of the video stre...

Abstract

The invention discloses a method for controlling the playing of a loudspeaker, and the method comprises the steps: enabling a mobile terminal to receive a video stream, and recognizing the screen mode of the video stream; employing a first loudspeaker and a second loudspeaker to play the audio information of the video stream if the screen mode of the video stream is recognized to be a lateral screen mode; employing one of the first and second loudspeakers to play the audio information of the video stream if the screen mode of the video stream is recognized to be a longitudinal screen mode. According to the scheme, the method automatically selects double channels or a single channel for playing flexibly, gives consideration to the stereophonic experience of a user, and also gives consideration to the endurance of the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method for controlling loudspeaker playback and a mobile terminal. Background technique [0002] Nowadays, in order to improve the competitiveness of mobile terminal products, major mobile terminal manufacturers will launch some high-tech and creative applications, such as screen projection, so as to improve the playability of mobile terminals. [0003] Existing mobile terminals can perform screen projection, and can also be used as a receiving end for screen projection. At present, mobile terminals also have dual speakers. When a mobile terminal with dual speakers is used as the receiving end of screen projection, it generally uses the preset single speaker or dual speakers to play by default. If dual speakers are used to play, if the user does not need stereo sound, the power consumption of the mobile terminal will be increased. Contents of the invention [...
