When the mobile phone detects that the user clicks an icon 302 of the album application on the desktop 301, the album application may be started, and a GUI as shown in (b) of fig. 3 is displayed, where the GUI may be referred to as an album interface. The photo album interface can display all photos, video collections, photo collections shot by a camera, photo collections acquired by a screen capture screen and the like in the mobile phone, wherein the videos stored in the mobile phone comprise the video 303.

Referring to (b) in fig. 3, when the mobile phone detects that the user clicks on the video set, the mobile phone may select to play the video 303 in the video set, and display a GUI as shown in (c) in fig. 3.

Referring to (c) in fig. 3, the interface is a playing interface of the video 303, and when the mobile phone detects that the user clicks the playing control 304, the mobile phone may play the video 303.

Referring to (d) in fig. 3, the interface is another playing interface of the video 303, and the mobile phone may play the video 303 through the speaker, where the volume of the mobile phone playing the video 303 through the speaker may be 8.

In one embodiment, the mobile phone may play the video 303 through a speaker, or may play the video 303 through an earphone or an external speaker.

It should be understood that the volume value of the mobile phone playing the video 303 through the speaker, the earphone or the external speaker may be the same or different, and is not limited herein.

Referring to (e) in FIG. 3, when the video 303 is played for 1 minute and 50 seconds, the mobile phone receives a message "Happy Birthday!sent by James through Wechat! The mobile phone may remind the user of the WeChat message through the WeChat message reminding window 304 and play a reminder of the WeChat message through the speaker, where the volume of the WeChat message played by the mobile phone through the speaker may be 2.

It should be understood that when the handset receives the message "Happy Birthday!from James of the user! And when the video is played, the mobile phone can continue to play the video.

In one embodiment, the mobile phone receives a message "Happy Birthday!from James of the user! When the user wants to play the WeChat reminding message, the volume of the mobile phone playing the WeChat reminding message through the loudspeaker is 2, and the volume of the mobile phone playing the video 303 through the loudspeaker when the WeChat reminding message is played can be smaller than or equal to 8.

It should also be appreciated that the duration for which the handset plays the reminder for the WeChat message through the speaker and displays the WeChat reminder message through the WeChat message reminder window 304 can be a predetermined duration.

For example, the duration of the WeChat reminder message played by the mobile phone through the speaker may be 1 second.

For example, the duration of the WeChat message displayed by the handset through the WeChat message reminder window 304 may be 3 seconds. After 3 seconds, the WeChat message reminder window 304 may automatically collapse/disappear.

Referring to (f) in fig. 3, when the video 303 is played for 2 minutes and 25 seconds, the alarm of the mobile phone rings, and the mobile phone can display the alarm information "8 o' clock and 12 minutes in the morning" in the alarm reminding window 305, and simultaneously the mobile phone can play the alarm ring through the speaker, wherein the volume of the alarm ring played through the speaker by the mobile phone can be 10.

In one embodiment, the cell phone may automatically pause the playing of the video 303 when the cell phone alarm rings.

In another embodiment, the cell phone may continue to play the video 303 when the cell phone detects that the user paused the alarm (e.g., the cell phone detects a user action to collapse the alarm bell window 305 upward).

It should be understood that the set of GUIs shown in fig. 3 introduces that in the same application, the volume values corresponding to different audio streams (streams) can be stored, wherein the volume values of different streams can be different or the same.

For example, the multimedia volume of the game APP can be set to 8, the notification volume to 1, and the warning volume to 0 by the user, so that the notification sound of the new message and the ringing sound of the alarm are relatively small when the game is played, and the game experience of the user is not affected.

For example, the user can set the notification volume to be 0 and the warning volume to be 0 under the fitness APP during fitness, so that the user can not be disturbed by new messages and alarms during fitness, thereby being capable of exercising with concentration and improving the user experience of the user during fitness.

For example, when a user is in a noisy environment and waits for a friend's phone while listening to music, the multimedia volume under the music APP can be set to 8 and the warning volume can be set to 12, so that when the mobile phone rings, the user can timely know the incoming call of the friend.

In the embodiment of the present application, the volume of the audio stream (stream) played by the mobile phone through the speaker includes, but is not limited to, multimedia (media) volume, call (call) volume, notification (notification) volume, and alert (alarm) volume. Wherein, the volume of the playing video 303 shown in fig. 3 may belong to the multimedia volume; the volume of the WeChat message may be the notification volume; the volume of the alarm bell may be the warning volume.

According to the method for controlling the volume, the corresponding relation between the type of the audio stream and the volume value is stored in the electronic equipment, so that the user can meet the requirements of the user on different volume values in different scenes, the intelligence of man-machine interaction can be improved, the user operation can be reduced, the learning cost of the user can be reduced, and the user experience can be improved.

In one embodiment, the volume of the stream (stream) output for different audio output devices may also be different.

The mobile phone can play the reminder of the WeChat message through the Bluetooth sound box, wherein the volume of the reminder of the WeChat message played by the mobile phone through the Bluetooth earphone can be 3.

Referring to the GUI shown in (c) of fig. 4, when the video 303 is played for 2 minutes and 25 seconds, the alarm of the mobile phone rings, and the mobile phone can play the alarm ring through the bluetooth speaker, wherein the volume of the alarm ring played by the mobile phone through the bluetooth speaker is 11.

It should be understood that the two sets of GUIs shown in fig. 3 and 4 describe the same application, and that different audio streams (streams) in different audio output devices may correspond to different volume values.

In the embodiment of the application, the volume values of the audio streams (stream) output by the mobile phone through different audio output devices can be different, which is beneficial to improving the user experience.

In the embodiment of the present application, the audio output device of the mobile phone includes, but is not limited to, a speaker (microphone), a headset (headset), a bluetooth device, and the like.

In one embodiment, the volume of the output audio stream (stream) may also be different for different bluetooth devices in the audio output device.

According to the method for controlling the volume, the corresponding relation among the connection type of the audio output device, the type of the audio stream and the volume value is stored in the electronic device, so that the user can meet the requirements of the user on different volume values in different scenes, the intelligence of man-machine interaction can be improved, the user operation can be reduced, the learning cost of the user can be reduced, and the user experience can be improved.

Fig. 5 shows another set of GUIs for a handset. The mobile phone can be connected with a Bluetooth headset, and the video 303 is played through the Bluetooth headset.

Referring to the GUI shown in (a) of fig. 5, the cell phone may play the video 303 through the bluetooth headset, wherein the volume of the video 303 played through the bluetooth headset by the cell phone may be 6.

Referring to the GUI shown in FIG. 5 (b), when the video 303 is played for 1 minute 50 seconds, the handset receives the message "Happy Birthday!sent by user James through Wechat!

In the embodiment of the application, the volume values of the audio streams (stream) output by the mobile phone through different bluetooth devices in the audio output device can be different.

It should be understood that the two sets of GUIs shown in fig. 4 and 5 describe the same application, and that different audio streams (streams) in different bluetooth devices may correspond to different volume values.

It should also be understood that the audio output device includes an earphone and a bluetooth device, and when the audio output device is connected to the mobile phone through a wired earphone, the audio output device may be an earphone; and through the mode of wireless connection, when cell-phone and bluetooth headset connect, this audio output equipment can be the bluetooth headset in the bluetooth equipment.

In the embodiment of the application, in different audio output devices, the volume value of the stream output through the Bluetooth headset can be smaller than the corresponding volume value of the stream output through the Bluetooth sound box, and sudden popping sound after the Bluetooth headset is carried by a user can be avoided, so that the user experience is promoted.

For example, when wearing a bluetooth headset, because the environment is noisy, the user often needs to adjust the volume of the bluetooth headset to a higher level to distinguish it from the ambient sound. When the Bluetooth loudspeaker box is connected to a Bluetooth sound box or a vehicle-mounted Bluetooth device, the Bluetooth volume needs to be adjusted in time to avoid popping. In the embodiment of the application, the mobile phone can be set under the same application program, the volumes of audio streams (streams) output by different audio output devices can be different, and when the earphone is worn, the mobile phone can play multimedia files such as music or video and the like according to higher multimedia volume, so that the multimedia files can be distinguished from environmental sounds; when the mobile phone is connected to the vehicle-mounted Bluetooth device, the mobile phone can automatically play multimedia files such as music or videos according to low multimedia volume, so that the influence of the pop sound on user experience is avoided.

In one embodiment, the audio streams (streams) may also have different volumes in different applications.

Fig. 6 shows another set of GUIs for a handset.

Referring to the GUI shown in (a) of fig. 6, the GUI is a desktop of a mobile phone. When the mobile phone detects that the user clicks the icon 601 of the music application on the desktop, the music application may be started, and a GUI as shown in (b) of fig. 6 may be displayed, where the GUI may be referred to as a music playing interface.

Referring to the GUI shown in fig. 6 (b), when the mobile phone detects the operation of the user clicking on the control 602, the mobile phone may play music "invisible wings".

Referring to the GUI shown in (c) of fig. 6, the handset may play music through a speaker, where the volume at which the handset plays music through the speaker may be 7.

Referring to the GUI shown in (d) of FIG. 6, when the mobile phone plays the music for 1 minute and 5 seconds, the mobile phone receives the WeChat message "Happy Birthday!sent by the user Frank! The mobile phone can remind the user of the content of the WeChat message through the WeChat reminding window 603 and can play the reminder of the WeChat message through the loudspeaker, wherein the volume of the reminder of the WeChat message played by the mobile phone through the loudspeaker is 0.

It should be understood that when the mobile phone receives the message "Happy Birthday!sent by the user Frank! When the music is played, the mobile phone can also continue to play the music.

In one embodiment, the mobile phone receives the message "Happy Birthday!sent from Frank! When the user wants to play the WeChat reminding message, the volume of the mobile phone playing the WeChat reminding message through the loudspeaker is 0, and the volume of the mobile phone playing the video 303 through the loudspeaker can be smaller than or equal to 7.

Referring to the GUI shown in (e) in fig. 6, when the mobile phone plays the music for 3 minutes and 19 seconds, the alarm of the mobile phone rings, and the mobile phone may display the alarm reminding information "8 o' clock 18 minutes in the morning" through the alarm reminding window 604, and simultaneously play the alarm ring through the speaker, wherein the volume of the alarm ring played through the speaker by the mobile phone may be 12.

It should be understood that in the two sets of GUIs shown in fig. 3 and 6, where different applications are introduced, different audio streams (streams) may correspond to different volume values.

In the embodiment of the application, the volumes of the audio streams (streams) of the same type may also be different in different applications, which may help to improve user experience.

For example, the electronic equipment is used for listening to music, watching videos and playing games every day, and the earphone is worn and taken off. Sometimes the user clearly remembers that the volume has just been turned down in the music APP, but that four jarring sounds are emitted while watching the video in the video APP. Or, the volume of the video APP used by the user is different when the user watches the video, and the user always needs to continuously adjust the proper volume. In the embodiment of the application, volume adjustment/setting of different APP and different audio streams (streams) is provided, so that the situation that a user adjusts the volume manually is avoided, the operation complexity of the user is reduced, the operation efficiency of the user is improved, the intelligent degree of the electronic equipment is improved, and personalized setting experience is provided for the user.

The above describes several sets of GUIs in the embodiments of the present application, and different audio streams in the same application may correspond to different volume values; alternatively, the same audio stream in different applications may correspond to different volume values; or, different audio streams output by the same audio output device in the same application program may correspond to different volume values; alternatively, the same audio stream output in different audio output devices in the same application may correspond to different volume values. Namely, in the embodiment of the application, the electronic equipment can store the corresponding relation of the APP ID-stream type-volume values; or the electronic equipment can store the corresponding relation of the APP ID-stream type-device-volume values.

The following describes a process of acquiring a specific volume value by an electronic device in an embodiment of the present application with reference to the drawings.

Fig. 7 shows a schematic flow chart of a method 700 of controlling a volume in an embodiment of the application, and referring to fig. 7, the method 700 includes:

the electronic device detects 710 a first operation by a user.

The first operation may be any operation of starting the APP, that is, as long as an effective operation of starting the APP by the user is detected.

For example, the first operation may be a preset specific operation, for example, the first operation is a specific general operation, such as double-click, long-press, pressure operation, finger joint operation, folding or unfolding of a screen, voice input, body sensing operation, and the like. The first operation may also be a specific function operation, for example, a certain function is turned on, and other functions are similar and will not be described again. Opening a certain function can be realized by opening a gesture (for example, opening a function of a telephone APP by sliding a C, opening an electronic mailbox APP by sliding an E, realizing a certain specific function by long-pressing and sliding a certain menu option on an icon, folding the foldable screen, and the like), or by clicking an APP icon, or by switching the APP from a background to a foreground, so that the first operation can be an opening gesture, an operation of clicking the APP icon, or a switching operation.

And 720, the electronic equipment responds to the first operation and determines the current application scene of the electronic equipment.

For example, after detecting that a user clicks an icon of a certain game APP on a desktop of the electronic device, the electronic device opens the game APP, displays an interface of the game APP, and enters a game scene. Specifically, after the electronic device detects that a user clicks an icon (e.g., a royal glory) of a certain game APP on a desktop of the electronic device, the game APP of the application layer sends a label (e.g., PID, UID, etc.) corresponding to the game APP and a process name corresponding to the game APP to the system service module of the framework layer, and the system service module can determine which APP is started through the label and the process name. For example, the electronic device determines that the game APP is started by determining the process identification number and the process name of the game APP. Of course, other existing techniques may be used to determine the APP currently running in the foreground.

The electronic device determines 730 the audio output device and the type of audio stream.

It should be understood that, in the embodiment of the present application, the electronic device determines the current application scenario and determines that there is no actual sequence between the audio output devices. For example, an audio output device (e.g., a headset, a bluetooth speaker, etc.) may have been connected to the electronic device prior to APP start-up; or after the APP is started, the electronic device detects that the audio output device is connected with the electronic device.

For example, when the user inserts the headset into the mobile phone, the mobile phone may obtain whether the headset channel is opened through an internal hardware-software interface. If the mobile phone is opened, the earphone is inserted currently, namely the mobile phone can determine that the currently adopted audio output equipment is the earphone.

For example, when the mobile phone is connected to the bluetooth speaker via bluetooth, the mobile phone may determine that the current audio output device is the bluetooth speaker via the bluetooth function.

Illustratively, when the handset determines that no headset is plugged in and not connected to any bluetooth device, the current audio output device may be determined to be a speaker.

For example, when the mobile phone determines that a video APP is started and detects that a user opens a certain video file, the mobile phone may determine that the type of the current stream is multimedia; when the mobile phone detects an incoming call event in the process of playing a video, the type of the current stream can be determined as ringing; when the mobile phone detects that the user hangs up the incoming call, the mobile phone can continue to play the current video file, so that the type of the current stream is determined to be multimedia.

It should be understood that, in the embodiment of the present application, for the process of determining the types of the audio output device and the stream in the current application scenario, reference may be made to an existing process, and details are not described herein for brevity.

740, the electronic device determines a corresponding volume value according to the identifier of the application program, the audio output device, and the type of the audio stream, wherein the electronic device stores a corresponding relationship among the identifier of the application program, the connection type of the audio output device, the type of the audio stream, and the volume value.

In one embodiment, each application in the electronic device may store a sound table (stream table) in which a correspondence relationship between UID-stream type-device-sound value is stored, where UID represents an identifier of each application program, stream type represents a type of a stream, and device represents a connection type of an audio output device. The UID of each application program in the electronic device is unique, and a volume table can be stored in each application program and used for searching the connection type of the audio output device and the volume value corresponding to the type of the audio stream under the application program.

The electronic device may initialize default values. For example, each time an application is installed on the electronic device, the system may monitor this information and initialize a default sound volume table for the UID corresponding to the application.

In one embodiment, the electronic device may set the sound meter at other times instead of setting the default sound meter at initialization.

For example, the electronic device may obtain a default set of volume tables at the first start-up; or when the electronic equipment starts a certain APP for the first time, the sound scale similar to the APP is obtained and used as the default sound scale.

For example, when the electronic device starts the internet cloud music for the first time, if the volume table of the QQ music is saved in the electronic device before, the electronic device may use the volume table of the QQ music as the default volume table of the internet cloud music.

It should be understood that the electronic device may initialize a default volume table for each APP, or may obtain the volume table from other locations.

For example, when the electronic device starts the youyou video for the first time, the default sound volume table of most users in the youyou video can be obtained from the server as the default sound volume table.

Illustratively, Table 1 shows a volume table for a photo album application.

Table 1 volume table corresponding to photo album application

For example, after the mobile phone installs the music APP, a set of volume tables for the music APP may be initialized. Table 2 shows the corresponding volume table for the music application.

Table 2 volume table for music application

It should be understood that, in table 1 and table 2 above, the magnitudes of the volume values corresponding to UID, stream, and device are merely illustrative, and the embodiment of the present application is not limited thereto.

It should also be understood that, in the embodiments of the present application, no limitation is made on the specific forms of the above tables 1 and 2. Illustratively, the corresponding relation of the UID-device-stream-volume value can be saved in the volume table. Illustratively, Table 3 shows a volume table for another album application.

Table 3 another volume table corresponding to photo album application

When the electronic device detects that the user opens the first application, the electronic device may determine, in the played track, which information is created by the first application corresponding to which UID, and then find the corresponding volume value according to the default volume table, the audio output device, and the type of the audio stream when the first application is initialized.

For example, referring to (d) in fig. 3, after the mobile phone detects that the user opens the album application, the mobile phone may determine that the current application scene is the album application; after the mobile phone determines that the video 303 in the album application is currently being played, the mobile phone may determine that the type of the current stream is multimedia and the audio output device is a speaker. The mobile phone may search the volume table stored in the album application, determine that the corresponding volume value is 8, and play the video 303 according to the volume value 8.

For example, referring to (a) in fig. 4, after the mobile phone detects that the user opens the album application, the mobile phone may determine that the current application scene is the album application; after the video 303 in the album application is currently being played, the mobile phone may determine that the type of the current stream is multimedia and that the audio output device is a bluetooth speaker. The mobile phone may search the volume table stored in the album application, determine that the corresponding volume value is 6, and play the video 303 according to the volume value 6.

When the electronic device detects that the user exits from the first application and starts the second application, the electronic device may determine, in the played track, information created by the second application corresponding to which UID corresponds, and then find the corresponding volume value according to the default volume table, the audio output device, and the type of the stream when the second application is initialized.

For example, as shown in fig. 6, after the mobile phone detects that the user exits from the album application and opens the music application, the mobile phone may determine that the current application scene is the music application. After the mobile phone determines that music "invisible wings" in the music application is currently being played, the mobile phone may determine that the type of the current stream is multimedia and the audio output device is a speaker. The mobile phone can search the volume table stored in the music application, determine that the corresponding volume value is 7, and play the music according to the volume value 7.

Fig. 8 is a schematic diagram illustrating a volume table corresponding to different applications stored in the electronic device in the embodiment of the present application.

In the embodiment of the application, the sound volume tables corresponding to different applications can be stored in the electronic device, the sound volume tables can represent the corresponding relations of the identification of the application program, the audio output device, the types of the streams and the sound volume values, the electronic device can be self-adaptive to different playing scenes to switch the sound volume values, the situation that a user always manually adjusts the sound volume is avoided, the operation complexity of the user is reduced, the operation efficiency of the user is improved, the intelligent degree of the electronic device is improved, and the user experience is improved.

In one embodiment, the volume table under each application may store a corresponding relationship between an identifier of the application, a type of the audio stream, a connection type of the audio output device, an identifier of the audio output device, and a volume value.

Fig. 9 shows another schematic diagram of the volume table corresponding to different applications stored in the electronic device in the embodiment of the present application.

For example, when a bluetooth device with a different identifier is accessed, the electronic device may record the identifier information of the current bluetooth device and record the volume saved by the current bluetooth device.

Illustratively, the identification information may be a MAC address of the bluetooth device. The MAC address may be a bluetooth MAC address of a bluetooth device or a WLAN MAC address.

Illustratively, Table 4 shows another volume table for the album application. The sound volume table is the corresponding relation of UID, stream type, device ID and sound volume value, wherein the device ID represents the identification of the audio output equipment.

It should be understood that, in the embodiment of the present application, the device may represent a connection type of the audio output device, and the device ID may represent an identifier of the audio output device. In the embodiment of the present application, the connection types of the audio output devices may be classified into speakers, wired audio output devices (e.g., wired headphones, wired speakers, etc.), wireless audio output devices (e.g., bluetooth headphones, bluetooth speakers, vehicle-mounted bluetooth devices, etc.), and the like. The identifiers of the speaker, the wired audio output device and the wireless connection device may be distinguished according to a uniform identifier, for example, the identifier is identified according to the device unique identifier of the audio output device, and the identification manner of the device unique identifier is not limited at all. The identifiers of the speaker, the wired audio output device, and the wireless audio output device may also be identified according to different identification manners, for example, the wired audio output device may be identified according to a level change rate of a software/hardware interface of the electronic device when the wired audio output device and the electronic device are connected, and the wireless audio output device may be identified according to a unique identifier such as a MAC address and an IP address of the device.

It should also be understood that, in the embodiment of the present application, a scheme in the prior art may be used for identifying a device, and other ways of identifying an audio output device may also be used in the future, and the embodiment of the present application is not limited thereto.

Table 4 another volume table corresponding to photo album application

In this embodiment, the unique identifier of the bluetooth device may be a MAC address of the bluetooth device, or may be other unique identifiers, for example, a ROM version number, a CPU model number, or a combination of one or more pieces of hardware information that can uniquely identify the bluetooth device.

In one embodiment, the volume table under each application may store the correspondence between the identifier of the application, the type of the audio stream, the identifier of the audio output device, and the volume value.

Illustratively, Table 5 shows another volume table for the album application. The sound volume table is the corresponding relation of UID, stream type, device ID and sound volume value.

Table 5 Another volume table corresponding to photo album application

For example, a "1" in the device ID may be an identification of the audio output device. For example, when the electronic device does not detect that a wired audio output device such as a headset is connected to the electronic device while playing audio, it may be determined that the identifier of the audio output device at this time is "1", which represents that the current audio output device is a speaker.

For example, "2" and "3" in the device ID may be the identification of a wired headset and a wired sound box, respectively.

For example, when the electronic device detects that a wired earphone is connected to the electronic device when playing audio, and the electronic device detects that the speed of level change of a software/hardware interface inside the electronic device is a first speed when the audio output device is inserted into the electronic device, the electronic device may determine that the identifier of the audio output device at this time is "2", which represents that the current audio output device is a wired earphone.

For example, when the electronic device detects that a wired headset is connected to the electronic device when playing audio, and the electronic device detects that a level change speed of a software/hardware interface inside the electronic device is a second speed when the audio output device is inserted into the electronic device, the electronic device may determine that the identifier of the audio output device at this time is "3", which represents that the current audio output device is a wired sound box, where the first speed and the second speed are different. Other prior art techniques may also be used to distinguish between different wired audio output devices connected to the electronic device and will not be described further herein.

For example, "4", "5", or "6", etc. may also be included in the device ID, which may be the identification of electronic devices having different MAC addresses or IP addresses, respectively. For example, when the electronic device detects that the bluetooth audio output device is connected to the electronic device when playing audio, the electronic device may learn the bluetooth MAC address of the electronic device, and the electronic device may determine a corresponding volume value according to the audio output device having different MAC addresses.

It should be understood that the device ID in table 5 above is merely exemplary, and other identification means are possible as long as the respective audio output devices connected to the electronic device can be identified and distinguished. For example, different MAC addresses may be used as the identifier of the audio output device, the level change speed may be used as the identifier of the wired audio output device, and the like, which is not limited in this embodiment of the present application. The method for controlling volume in the embodiment of the present application is described above by the method 700, and a GUI interface and a method for adjusting volume value in the embodiment of the present application are described below.

Referring to the GUI shown in (a) of fig. 10, the GUI is another music application interface of the electronic device. When the mobile phone detects that the user presses the volume key during the music playing process of the mobile phone, for example, the volume value 7 corresponding to the original multimedia volume is adjusted to 9. In this case, the handset may also adjust the volume table saved in the music application, for example, the volume value corresponding to the stream type being multimedia and the audio output device being a speaker is adjusted to 9.

It should be understood that if the mobile phone does not detect the operation of adjusting the volume value of the multimedia by the user again before the mobile phone detects that the user exits the music application, the mobile phone may automatically save the volume value corresponding to the audio output device being the speaker with the type of the audio stream in table 2 being the multimedia as 9.

In one embodiment, the mobile phone can adjust the volume table corresponding to the music application every time the mobile phone detects that the user adjusts the corresponding volume value in the music application; or, the mobile phone may also keep the volume table corresponding to the current music application when detecting that the user exits or moves back to the background.

Referring to the GUI shown in (b) of fig. 10, the GUI is another music application interface of the electronic device. When the mobile phone plays music for 1 minute and 5 seconds, the mobile phone receives the WeChat message, and the mobile phone can determine that the reminding volume value of the loudspeaker for the WeChat message is 3 according to the volume table shown in the table 2. At this time, when the mobile phone detects the operation of pressing the volume key by the user, for example, the volume value 3 corresponding to the original notification volume is adjusted to 0. In this case, the handset may also adjust the volume table saved in the music application, for example, the volume value corresponding to the stream type being notification and the audio output device being a speaker is adjusted to 0.

It should be understood that when the mobile phone detects a WeChat message sent by the user Frank, the mobile phone may determine that the adjustment is for notifying the type of flow if the operation of adjusting the volume value by the user is detected within a preset time period from the display of the reminder window 603. For example, the mobile phone may determine that within 3 seconds from the display of the reminder window 603, if it is detected that the user adjusts the volume value, the mobile phone may adjust from the volume value 3 corresponding to the notification volume, as shown in fig. 3 (b), and the mobile phone adjusts the volume value corresponding to the notification volume from 3 to 0.

It should also be understood that if the handset does not detect again the user's operation of adjusting the volume value of the notification before the handset detects that the user exits the music application, the handset may automatically save the volume value corresponding to the type of the stream in table 2 as the notification and the audio output device as the speaker as 0.

In one embodiment, during the time period when the mobile phone displays the reminder window 603, if the operation of pressing the volume key by the user is detected, the mobile phone may determine that the adjustment is an adjustment of the volume value corresponding to the notification volume.

In an embodiment, when the mobile phone displays the reminding window 603, if the operation of pressing the volume key by the user is detected, the mobile phone can remind the user to select the type of the adjusted audio stream through the reminding window, and after the user selects the type of the audio stream to be adjusted, the mobile phone can adjust the type of the corresponding audio stream. For example, the mobile phone may prompt the user to "whether to adjust the notification volume", and when the mobile phone detects that the user determines to adjust the notification volume, the mobile phone may adjust the volume value corresponding to the notification volume.

Referring to the GUI shown in (c) of fig. 10, the GUI is another music application interface of the electronic device. When the mobile phone plays music for 1 minute and 5 seconds, the alarm of the mobile phone rings, and the mobile phone can determine that the volume value of the loudspeaker for the alarm ring is 12 according to the volume table shown in table 2. At this time, when the cellular phone detects the operation of pressing the volume key by the user, for example, the volume value 12 corresponding to the original warning volume is adjusted to 8. In this case, the handset may also adjust the volume table saved in the music application, for example, the volume value corresponding to the stream type being a warning and the audio output device being a speaker is adjusted to 8.

It should be understood that if the alarm has a ring duration of 60 seconds, the display duration of the reminder window 604 may be 60 seconds when the alarm of the cell phone rings. After 60 seconds, the reminder window 604 can automatically close and the alarm ringing can automatically end. When the handset detects an operation of the user to adjust the volume value in these 60 seconds, the handset can determine that the adjustment is an adjustment for which the type of stream is a warning.

It should also be understood that if the handset does not detect again the user's operation to adjust the volume value of the alert before the handset detects that the user exits the music application, the handset may automatically save the volume value corresponding to the type of stream in table 2 as alert and the audio output device as a speaker as 8.

Illustratively, table 6 shows another volume table corresponding to the music application updated by the music application after the mobile phone exits the music application.

Table 6 another volume table for music applications

The above introduces a way for the mobile phone to save the updated volume table when the user adjusts the volume value in real time through the volume control key. An alternative set of GUIs for adjusting volume values in the embodiments of the present application is described below.
