Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the conventional art, as shown in fig. 1, when an electronic device 101 is applied to a dual/multi-screen display state through an external display device 102, can only provide audio output (playing) function for one of the local or external display device of the electronic device, and can not provide audio output function for both the local and external display devices, more specifically, referring to fig. 2, the audio output configuration interface of the electronic device may be called up through a horn icon in a desktop taskbar (e.g. lower right corner) of the electronic device 101, in the interface, the default configuration is to provide an audio output function for the external display device, and the electronic device cannot output audio for the local device, and if the user has different requirements, the audio output function of the device can be switched to the local device only by selecting the 'forbidden' option in the configuration interface of fig. 2, and meanwhile, the external display device cannot output audio.
The above limitation of the conventional technology in the dual/multi-screen display state brings inconvenience to the user using the electronic device, and a typical scenario is that the user plays a game by using the local display screen and plays a movie by using an external screen (it may be that one user plays the game and watches the movie at the same time, or that one or some users of two or more users play the game and another/some users watch the movie), and in the conventional technology, the audio playing can be performed only for the video frame of one screen, so that the limitation is brought to the device application in the dual/multi-screen display state, and the one-machine multi-use in the true sense cannot be realized.
Therefore, the present application provides a control method and an electronic device, which aims to overcome the above problems of the conventional technology, so as to provide an audio output function for both a device local machine and an external display device of the electronic device in a dual/multi-screen display state, thereby realizing one machine with multiple functions in the true sense.
In an alternative embodiment of the present application, a control method is disclosed, which can be applied to an electronic device with an audio output device, such as but not limited to a portable computer (e.g., a mobile phone, a tablet, a notebook, etc.), a desktop computer, a midrange computer, etc. in a general/special purpose computing or configuration environment. The audio output device of the electronic device may generally include an internal audio output device (e.g., an internal speaker) of the device, and/or an audio interface for accessing an external audio output device (e.g., an earphone, a sound box), where the audio interface may be, but is not limited to, an audio interface based on wired/wireless technologies such as USB (universal serial Bus) or bluetooth.
Referring to fig. 3, in the present embodiment, the control method may include:
The electronic equipment such as a notebook computer, a desktop computer and the like can realize double/multi-screen display by externally connecting display equipment, when a user has a demand of one machine with multiple functions and needs to extend one or more external display devices for the electronic equipment, one or more required display devices may be accessed at a corresponding Multimedia Interface of the electronic device, e.g., one or more interfaces such as VGA (Video Graphics Array), DP (display Interface) and/or HDMI (High Definition Multimedia Interface), therefore, information can be displayed on the display screen of the electronic equipment and the screens of one or more external display devices simultaneously, and it is easy to understand that the double/multi-screen display functions provided by the display screens of the electronic equipment and the external display devices are supported by the host of the electronic equipment and share the data processing function provided by the host of the electronic equipment.
In order to provide audio output functions for the local computer and the external display device respectively in a dual/multi-screen display state, in the embodiment of the application, whether the electronic device is externally connected with the display device is detected firstly, so that an indication can be provided for triggering different processing under the condition that the display device is externally connected and under the condition that the display device is not externally connected.
Conventionally, electronic devices such as a notebook computer and a desktop computer have a built-in audio output device, such as a built-in speaker, and also have an audio interface capable of being connected to an external audio output device (such as an earphone and a sound box), and both the built-in audio output device and the audio interface of the electronic device can support audio output; for example, the external display devices of various types supporting the VGA interface generally do not have audio output devices such as a built-in speaker and an audio interface of an earphone/speaker, and cannot output audio by using the audio output device of the display device itself, and the display devices of various types supporting the DP/HDMI interface generally have audio output devices, such as a built-in speaker and an audio interface of an earphone/speaker, so that the display devices of these types can support playing audio by using the audio output device of the display device itself.
In the present embodiment, in combination with the above situations of the electronic device and the external display device, when it is detected that the display device is connected to the electronic device, the first indication information capable of indicating the audio output device of the electronic device and the second indication information capable of indicating the audio output device of the external display device are continuously obtained. The electronic device can respectively know the configuration conditions of the electronic device and the audio output devices of the external display device based on the first indication information and the second indication information, such as whether the electronic device has the audio output device, which (built-in or external) audio output devices, and whether the external display device has the audio output device, which (built-in or external) audio output devices.
In summary, the electronic device can respectively know the configuration of the audio output devices of the electronic device itself and the external display device based on the first indication information and the second indication information, and can further adapt to a suitable audio output mode according to the audio output devices actually configured by the electronic device itself and the external display device after knowing the configuration of the audio output devices of the electronic device itself and the external display device.
The determined audio output mode is used for indicating different target audio output devices adopted by audio output for the electronic equipment and the external display equipment respectively, and aims to effectively utilize the audio output devices, such as a built-in loudspeaker, an audio interface capable of being externally connected with an earphone/a sound box and the like, of the electronic equipment and/or the external display equipment, and simultaneously provide audio output functions for the electronic equipment and the external display equipment so that the electronic equipment and the external display equipment can play audio simultaneously.
And 304, controlling audio output of the electronic equipment and the display equipment based on the audio output mode, so that a first audio output function is provided for the electronic equipment and a second audio output function is provided for the display equipment at the same time based on at least an audio output device of the electronic equipment.
After the audio output mode is determined, different target audio output devices can be respectively allocated to the electronic equipment and the external display equipment based on the audio output mode, so that the target audio output devices allocated to the electronic equipment and the external display equipment can be driven, and an audio output function is provided for the electronic equipment and the external display equipment.
It should be noted that, in an actual application scenario, the electronic device generally has both a built-in speaker and an audio interface capable of accessing an earphone/sound box, and the external display device may have or may not have an audio output device according to different device models, so that when providing an audio output function for the electronic device and the external display device simultaneously based on a determined audio output mode, the electronic device and the external display device may be provided with an audio output function for the electronic device and the external display device respectively by using only different audio output devices of the electronic device itself, or by using respective audio output devices of the electronic device and the external display device, respectively providing an audio output function for the respective devices, which is not limited in this application.
Through the technical scheme, the control method provided by the application determines the audio output modes of the electronic equipment and the external display equipment by combining the actual conditions of the audio output devices of the electronic equipment and the external display equipment under the condition that the electronic equipment is externally connected with the display equipment, and provides the first audio output function for the electronic equipment and simultaneously provides the second audio output function for the external display equipment based on at least the audio output device of the electronic equipment when the audio output control is performed on the electronic equipment and the external display equipment based on the determined audio output modes, so that the application realizes that the audio output functions are respectively provided for the local equipment and the external display equipment under the double/multi-screen display state, breaks through the limitation that only one of the local equipment and the external display equipment can be provided with the audio output function under the double/multi-screen display state in the traditional technology, the multi-purpose device is multifunctional from the aspect of audio output, and the functions of the device in a double/multi-screen display state are enriched.
Referring to fig. 4, in an alternative embodiment of the present application, the control method may be further implemented by the following processing procedures:
The preset pin is connected with at least one multimedia interface of the electronic equipment, and the multimedia interface can be used for being externally connected with display equipment.
The first audio codec of the electronic device is a sound card chip of the electronic device.
The number of the preset pins may be one or more.
The predetermined signal may be, but is not limited to, a General-purpose input/output (GPIO) signal.
In this embodiment, optionally, the detection pin is led out from the sound card chip of the electronic device, and is accessed to the multimedia interfaces of the electronic device, such as VGA, DP, and/or HDMI, for example, the VGA interface is accessed to the first detection pin of the sound card chip, the DP interface is accessed to the second detection pin of the sound card chip, and the HDMI interface is accessed to the third detection pin of the sound card chip. The multimedia interface of the electronic equipment is usually in a high level state when no external equipment is connected, and when the external equipment is connected, the level of the multimedia interface is pulled down and is in a low level state.
Otherwise, if the detection pin of the sound card chip does not receive the GPIO signal, it indicates that no display device is connected to the multimedia interface connected to the detection pin.
402, if yes, acquiring first detection information of a built-in audio output device and/or an audio interface of the electronic equipment as the first indication information; the audio interface is used for externally connecting an audio output device.
When the electronic equipment is detected to be externally connected with the display equipment, first indication information capable of indicating an audio output device provided by the electronic equipment and second indication information capable of indicating the audio output device provided by the externally connected display equipment are continuously acquired. More specifically, the first indication information can be used to indicate the configuration of the audio output device of the electronic device, such as whether the electronic device has the audio output device, which (built-in or external) audio output devices are provided, and similarly, the second indication information can be used to indicate the configuration of the audio output device of the external display device, such as whether the external display device has the audio output device, which (built-in or external) audio output devices are provided, and the like.
In this embodiment, first detection information of a built-in audio output device and/or an audio interface of an electronic device is acquired and used as the first indication information.
More specifically, as an optional implementation manner, the first detection information may be obtained by reading related configuration information about the audio output devices in the detailed configuration information of the electronic device, such as which audio output devices (internal speakers, audio interfaces) the electronic device has, and related specification parameters of the audio output devices; or, as another optional implementation, the device model of the electronic device may be detected (usually, the electronic device of a specific model has a matched hardware configuration), and based on the correspondence between the maintained device model and the configuration information of the audio output devices such as the built-in speaker and the audio interface, the relevant configuration information of the audio output devices of the electronic device (which audio output devices and their specification parameters are configured, etc.) may be further determined, and is used as the first detection information, that is, the first indication information.
the electronic equipment is externally connected with an interface type of a multimedia interface of the display equipment;
the equipment model of the externally connected display equipment;
and second detection information of a built-in audio playing device and/or an audio interface of the display equipment.
As an optional implementation manner, the second indication information may be obtained as an interface type of a multimedia interface, such as VGA, DP, or HDMI, of the electronic device, where the display device is externally connected. In general, each model of display device supporting the VGA interface does not have an audio output device such as a built-in speaker and an audio interface of an earphone/speaker, and each model of display device supporting the DP/HDMI interface generally has an audio output device such as a built-in speaker and an audio interface of an earphone/speaker, so that configuration information of the audio output device indicated by different interface types can be preset, for example: the VGA interface type indicates that the external display equipment does not have an audio output device, and the DP/HDMI interface type indicates that the external display equipment has a built-in loudspeaker and audio output devices such as an audio interface.
As another optional implementation, the device model of the external display device may be obtained as the second indication information, each device model is usually matched with a corresponding hardware configuration, and the configuration information of the audio output device indicated by each device model may be preset based on the hardware configuration actually corresponding to each device model, so that when the display device is accessed on the multimedia interface of the electronic device, the configuration condition of the audio output device may be determined by obtaining the device model of the external display device.
As still another optional implementation, the second detection information for the built-in audio output device and/or the audio interface of the external display device may also be directly acquired as the second indication information.
In the latter two embodiments, referring to fig. 5 in particular, a group of pins may be preset on the sound card chip as protocol channel pins of the electronic device and the external display device, for example, pin 6(I2C-DATA) and pin 7(I2C-CLK) on the sound card chip ALC274-CG in fig. 5 are set as the protocol channel pins, once the sound card chip of the electronic device detects that the display device is connected to the multimedia interface, the group of pins is used to perform protocol communication with the external display device, and specifically, the group of pins is used to capture relevant information of the external display device through the multimedia interface based on a predetermined protocol, specifically, but not limited to capture device model, resolution and/or speaker of the external display device, configuration information of the audio interface, and so on, and the device model and/or speaker, configuration information of the audio interface therein, as the second indication information.
If the second indication information indicates that the display device does not have an audio output device, it indicates that the audio output device of the electronic device itself, such as an internal speaker and an audio interface of the electronic device (which may be connected to an external audio output device such as an earphone or a sound box), can only be utilized to provide an audio output function for the electronic device and the external display device at the same time, and in this case, the audio output mode of the electronic device in the dual/multi-screen display state is determined as the first output mode.
On the contrary, if the second indication information indicates that the display device has the audio output device, it indicates that the audio output device of the electronic device and the audio output device of the external display device can be utilized to provide the audio output function for the electronic device and the external display device at the same time, respectively, in this case, the audio output mode of the electronic device in the dual/multi-screen display state is determined as the second output mode.
And 406, in the first output mode, using different output devices in the built-in audio playing device and the external audio output device of the electronic device to respectively perform audio output on the audio to be output by the electronic device and the display device.
Correspondingly, in the first output mode, the sound card chip of the electronic device can be used to control different audio output devices such as a built-in audio output device of the electronic device itself and an audio interface (which can be connected to an external audio output device such as an earphone or a sound box) to perform two/multiple audio outputs, so as to provide an audio output function for the electronic device and an external display device thereof at the same time.
Specifically, referring to fig. 5, the sound card chip may control two audio channels, namely, an audio output channel (e.g., a LEFT channel LINE _ LEFT and a RIGHT channel LINE _ RIGHT in fig. 5) of a built-in speaker of the electronic device and an audio output channel (e.g., a LEFT channel HP _ OUTL and a RIGHT channel HP _ OUTR in fig. 5) of an audio interface of the electronic device to open, so as to simultaneously provide an audio output function for a display screen of the electronic device and an external display device of the electronic device, and further, the audio output channel of the built-in speaker of the electronic device may be used to output an audio to be played by the electronic device, and the audio output channel of the audio interface of the electronic device may be used to output an audio to be played by the external display device to an external earphone or a sound box, or the audio output channel of the built-in speaker of the electronic device may be used to output an audio to be played by the external display device to the external earphone or the sound box.
Typically, in a dual-screen application scenario, if a user plays a game using a display screen of the electronic device itself and watches a movie using an external display screen, the user may play a game audio (or play a movie audio) using a built-in speaker of the electronic device itself and play a movie audio (or play a game audio) using an earphone connected to an audio interface of the device itself, and of course, in the actual application scenario, the same user may play the game while watching the movie, or some users among different users may play the game on the display screen of the device itself and another user/users may watch the movie on the extended display screen.
In the second output mode, the audio output device of the electronic equipment and the external display equipment can be combined and utilized, and the audio output function is provided for the electronic equipment and the external display equipment. Preferably, the audio output device of the electronic device is used for audio output of the audio required to be output by the electronic device, and the audio output device of the display device is used for audio output of the audio required to be output by the display device.
In the first mode, different audio output devices of the electronic equipment are utilized to simultaneously provide audio output functions for the electronic equipment and the external display equipment respectively, and correspondingly, a sound card chip of the electronic equipment can directly control corresponding audio output channels to output audio to corresponding audio output devices of the electronic equipment, so that the audio data does not need to be output to the external display equipment through a multimedia interface; in the second output mode, the electronic device local machine may transmit the audio to be played by the external display device to a second audio codec of the external display device through a multimedia interface accessed by the external display device, that is, to a sound card chip of the external display device, decode the received audio data by the sound card chip of the external display device, and transmit the decoded audio to an audio output device (such as a built-in speaker or an external earphone/sound device) of the external display device for output.
A specific application example of the present application is provided below, in this example, as shown in fig. 6, after the electronic device is powered on, it may first detect whether the electronic device is externally connected with a display, and if so, may continue to detect an interface type of a multimedia interface accessed by the externally connected display, where if the detected multimedia interface type is DP or HDMI, a second output mode is adopted, and the electronic device sound card chip controls to provide an audio output function for the local display screen of the electronic device by using an audio output device (a speaker is built in or an audio interface accessed with an earphone/speaker) of the electronic device, and simultaneously controls the audio output device (a speaker is built in or an audio interface accessed with an earphone/speaker) of the externally connected display device to provide an audio output function for the externally connected display device; if the detected multimedia interface type is VGA, a first output mode is adopted, and the sound card chip of the electronic equipment controls different audio output devices of the electronic equipment, such as a built-in loudspeaker of the electronic equipment and an audio interface connected with an earphone/a sound box, and simultaneously provides an audio output function for a display screen of the electronic equipment and an external display device.
Of course, other forms of application situations are also possible, such as determining an output mode to be adopted according to the device model of the external display device and/or the detection information of the audio output device of the external display device, and controlling different audio output devices in the electronic device and/or the external display device to simultaneously provide an audio output function for the local display screen of the electronic device and the external display device, perform audio output, and the like.
