Referring to fig. 4, fig. 4 is a schematic diagram of a volume control method according to an embodiment of the present application.

Step S41: the second electronic device transmits the first volume to the first electronic device.

In the embodiment of the application, the second electronic device obtains its own volume, namely, the first volume. Before the first electronic device establishes a connection with the second electronic device, or before the first electronic device transmits audio data to the second electronic device, the second electronic device transmits a first volume to the first electronic device, e.g., the second electronic device broadcasts its first volume to the first electronic device.

The volume in the embodiment of the present application may be a system volume (master volume), which may be understood as a volume affecting all sounds of the electronic device. The system volume can be written to the sound card to control the volume of all sounds of the electronic device. Instead of writing to the sound card, it is also possible to influence the volume of all sounds of the electronic device as a multiplier factor. In other words, the system volume is set, that is, all of the application volume (AudioTrack volume) and the stream volume (stream volume) are set. Where, when an application sets AudioTrack volume, only the volume of that application is affected. The stream volume is the volume of a certain audio stream, i.e. when a certain audio stream sets a stream volume, the volume of that audio stream is only affected.

In some embodiments, the volume may be a streaming volume, where the volume of an audio stream (stream) includes, but is not limited to, a multimedia (media) volume, a call volume, a notification volume, and an alert volume. Wherein the volume of the played video may belong to the multimedia volume; the volume of the WeChat message may belong to the notification volume; the volume of the alarm can belong to the warning volume.

It should be noted that, in the embodiment of the present application, the audio device corresponding to the Sound volume includes, but is not limited to, a Sound Card (Sound Card), a speaker (speaker), a headset (headset), and a bluetooth device.

In the embodiment of the present application, the volume may be expressed as a volume ratio (percentage). The percentage represents the proportional relation between the playing volume corresponding to the volume and the maximum playing volume of the electronic equipment. The larger the corresponding percentage of the volume is, the larger the corresponding play volume of the volume is, the smaller the corresponding percentage of the volume is, and the smaller the corresponding play volume of the volume is. For example, the playback volume of 50% is half the maximum playback volume of the electronic device.

In some embodiments, the volume may be represented by a particular value. The specific value represents the relative relation between the playing volume corresponding to the volume and the maximum playing volume of the electronic equipment. The larger the corresponding value of the volume is, the larger the corresponding play volume of the volume is, the smaller the corresponding value of the volume is, and the smaller the corresponding play volume of the volume is. For example, a play volume corresponding to a volume value of 200 is a maximum play volume, and a play volume corresponding to a volume value of 50 is 25% of the maximum play volume.

In some embodiments, the volume may be expressed in decibels (dB). For example, the volume is 30dB.

In some embodiments, the volume is set to 0-N levels, which may be represented by levels. And when the value of the volume is 0, the mute state is represented, and the larger the level of the volume is, the larger the volume is represented. It should be noted that, the value of N and the division of the volume size may be set by the user according to the needs, for example, N is set to 5, and the volume is divided into six levels, namely, level 0-mute, level 1 (mute-20% of the maximum play volume), level 2 (21% of the maximum play volume-40% of the maximum play volume), level 3 (41% of the maximum play volume-60% of the maximum play volume), level 4 (61% of the maximum play volume-80% of the maximum play volume), and level 5 (81% of the maximum play volume-maximum play volume). The volume may be expressed in terms of a decibel, as well as a percentage, which is not specifically limited in the embodiment of the present application. Taking n=5 as an example, when the correspondence between the storage level and the volume level is adopted, the following format shown in table 1 may be adopted:

TABLE 1

Volume size	Grade
		Mute	0
Mute-20% of maximum play volume	1
		21% size of maximum play volume-40% size of maximum play volume	2
41% of maximum play volume-60% of maximum play volume	3
		61% size of maximum play volume-80% size of maximum play volume	4
81% of maximum play volume-maximum play volume	5

In the embodiment of the present application, the above various modes of representing the volume may be converted, and the conversion relationship between the volume percentage and the decibel is shown in the following table 2:

TABLE 2

Percentage (%)	Decibels (dB)
		10	20
20	30
		30	40
40	50

For example, the second electronic device may acquire its own volume currently, i.e. the first volume, through the function getMasterVolume, and then add information about the first volume in a custom extension field of the communication protocol, and broadcast the information to the outside. Among them, communication protocols include, but are not limited to, bluetooth low energy (Bluetooth Low Energy, BLE) protocol, restricted application protocol (Constrained Application Protocol, coAP).

In the embodiment of the application, the second electronic device may broadcast the corresponding device identifier to the outside while broadcasting the corresponding first volume to the outside. The first electronic device receives the broadcast and can know the device identifier and the first volume corresponding to the second electronic device. Wherein the device identification is used for uniquely identifying the second electronic devices, i.e. the device identification of each second electronic device is unique, and the device identifications of the respective second electronic devices are different. The device identification may be an internet protocol address (Internet Protocol Address, IP address) or a device number, among others.

It can be appreciated that when the number of second electronic devices includes a plurality of second electronic devices, each second electronic device can acquire the corresponding first volume. Any second electronic device can broadcast the corresponding first volume and the device identifier to the first electronic device in a broadcasting mode. Any second electronic device whose device identification is associated with its first volume. When the first electronic device receives the broadcast of the plurality of second electronic devices, the first electronic device can obtain the device identification of each second electronic device and the first volume associated with the device identification.

The following describes the system volume in terms of volume and the volume expressed in terms of percentage.

Step S42: the first electronic device obtains a first volume of the second electronic device and displays the first volume.

In the embodiment of the application, the first electronic device receives a first volume broadcast by the second electronic device and displays the first volume. The first electronic device has a display function, for example, the first electronic device has a display screen, and the first electronic device displays the received broadcast information (such as a first volume and a device identifier) through the display screen. Or the first electronic equipment transmits the received broadcast information (such as the first volume and the equipment identifier) to other peripheral equipment with a display screen, and the information is displayed through the display screen of the peripheral equipment. The first electronic device informs the user that the first volume displayed currently is the current volume of the second electronic device by displaying the first volume. The first electronic device informs the user of the current volume of each second electronic device by displaying the first volumes of the plurality of second electronic devices.

In this embodiment of the present application, the first electronic device may acquire the first volume of the second electronic device, which may be that the first electronic device may actively request the first volume of the second electronic device to the second electronic device, and the second electronic device may send the first volume of the second electronic device to the first electronic device in response to the request, or may also be that the first electronic device receives the first volume broadcast by the second electronic device, which is not specifically limited in this application.

In the embodiment of the application, when the first electronic device obtains the first volume of the second electronic device, the first electronic device has not yet transmitted the audio data to the second electronic device. Or, before the first electronic device does not transmit the audio data, the first electronic device obtains the first volume of the second electronic device. Or, the first electronic device has previously transmitted the audio data to the second electronic device, and now the first electronic device does not transmit the audio data to the second electronic device, and the first electronic device obtains the first volume of the second electronic device.

In the embodiment of the application, when the first electronic device displays the first volume of the second electronic device, the display identifier of the second electronic device may also be displayed at the same time. The display identifier is used for distinguishing each second electronic device, so that a user can conveniently determine the second electronic device corresponding to the display identifier through the display identifier. The display identifier is related to the device identifier, and the different second electronic devices have different corresponding device identifiers, and accordingly, the corresponding display identifiers can also be different. The user can know which electronic device is currently the second electronic device through the display identifier, or know the electronic device corresponding to the first volume.

In the embodiment of the application, different display identifiers can be preset for different device types. The first electronic device may determine a device type of the second electronic device according to the device identifier of the second electronic device, and further display a corresponding display identifier according to the corresponding device type. For example, if the device type of the electronic device is a mobile phone, the corresponding display identifier is a mobile phone identifier. If the equipment type of the electronic equipment is a computer, the corresponding display identifier is a computer identifier. If the device type of the electronic device is a headset, the corresponding display identifier is a headset identifier. If the device type of the electronic device is a smart screen, the corresponding display identifier is a smart screen identifier. If the equipment type of the electronic equipment is a sound box, the corresponding display identifier is the sound box identifier. If the device type of the electronic device is a tablet, the corresponding display identifier is a tablet identifier.

In some embodiments, the display identification may be implemented as a device icon. If the mobile phone identifier is realized as a mobile phone icon, the computer identifier is realized as a computer icon, the intelligent screen identifier is realized as an intelligent screen icon, the earphone identifier is realized as an earphone icon, the sound box identifier is realized as a sound box icon, and the tablet identifier is realized as a tablet icon.

In some embodiments, the display identifier may also be implemented as a text identifier, e.g., the text identifier may be: notebook (MateBook), speaker (Sound X), earphone (HUAWEI FreeBuds), tablet (MatePad Pro), smart screen, etc.

In some embodiments, the display identifier may be implemented as a text identifier and a corresponding device icon, for example, the electronic device is a notebook, and the corresponding display identifier may include the notebook icon and a corresponding text identifier "MateBook".

It is to be understood that the display identifier may also be implemented as one or more of a symbol, a word, a control, etc., and the specific form of the display identifier is not specifically limited in this application.

In some embodiments, corresponding display modes may be set for the volumes of different volume sizes in advance. The first electronic device can display a plurality of volumes with different volumes respectively in different display modes. When the first electronic device displays the first volume, a display mode corresponding to the first volume can be determined according to the first volume, and then the first volume is displayed according to the corresponding display mode. The first electronic equipment respectively displays a plurality of first volumes with different volumes in different display modes, and the volumes of the first volumes are distinguished in different display modes, so that a user can be informed of the difference of the volumes of the first volumes. The user can be informed whether the current first volume of the second electronic device is suitable for playing the audio or not through the display mode. If the first volume of the second electronic device is too large, the first electronic device may also prompt the user to modify the volume of the second electronic device.

In the embodiment of the application, different ranges of the volume of the first volume can be divided according to actual conditions, and corresponding display modes are set for the different ranges. Illustratively, the volume size is expressed in percent, dividing the volume size into four ranges, the first range being: greater than or equal to 0 and less than 25%, corresponding to the first display mode. The second range is: greater than or equal to 25% and less than 50%, corresponding to the second display mode. Third range: greater than or equal to 50% and less than 75%, corresponding to the third display mode. Fourth range: greater than or equal to 75% and less than or equal to 100%, corresponding to the fourth display mode. The first display mode is different from the fourth display mode.

In the embodiment of the application, the display mode may include display color, display style, display numerical value and the like. Wherein, the display color may include: hue, color saturation, brightness, etc. For example, the hues may exhibit a distinction of red, orange, yellow, green, blue and violet. The display style may include display pattern, display shape, fill type, fill area, and the like. The display values may include specific values, such as percentages or decibels, etc.

In some embodiments, the display may be implemented as volume icons and the different display of the first volume may be represented as a distinction of volume icons. And displaying the volume icons on the super terminal interface in a line form, wherein the lines with different lengths represent different volume icons, and the lines with different lengths represent different display modes, namely represent different volume ranges (or volume sizes). Or the lines with different colors represent icons with different volumes, and the lines with different colors represent different display modes, namely represent different volume ranges (or volume sizes). Or a different number of lines representing different volume icons, a different number of lines representing different display modes, i.e. representing different volume ranges (or volume sizes). The corresponding value (such as a percentage or a decibel) of the first volume can also be displayed, and the volume of the first volume is known according to the value. It will be appreciated that the representation of the volume icons, and the differentiated display of the volume icons, is not limited to the above description, and embodiments of the present application are not specifically limited thereto.

In some embodiments, the first electronic device may display a display identifier belonging to the same second electronic device in association with the first volume. Through the associated display, the user can know the first volume of the second electronic device corresponding to the display identifier. If the display identifier of the second electronic device is a, the corresponding first volume is B. And the first electronic equipment displays the A and the B in an associated way, so that the user can know that the first volume of the second electronic equipment corresponding to the display identifier A is B.

In the embodiment of the application, when the first electronic device receives the broadcast of the plurality of second electronic devices, the display identifiers of the plurality of second electronic devices may be displayed in different display areas. The display of the display identifier and the first volume associated display may be implemented by dividing a display interface of the first electronic device, such as a super terminal interface, into a plurality of display areas, where each second electronic device uniquely corresponds to one display area, and displaying a device icon and a volume icon belonging to the same second electronic device in the display area corresponding to the second electronic device, that is, displaying the device icon and the volume icon belonging to the same second electronic device in the display area corresponding to the second electronic device in a manner of approaching.

A second electronic device having broadcast capabilities in the vicinity of the first electronic device may broadcast its device identification and the first volume. In the super terminal scene, the first electronic device receives broadcast information of the second electronic device meeting the discovered device condition, and the broadcast information displays the device identification and the first volume of the second electronic device. It can be understood that in other scenarios, after receiving the broadcast information of the second electronic device, the first electronic device may display the device identifier and the first volume of the second electronic device, and the second electronic device is not specifically limited.

In an exemplary embodiment, the first electronic device is a mobile phone, the volume icon is a line around the periphery of the device icon, and different lengths of the line represent different volume levels. The user can search for the second electronic device in the vicinity of the mobile phone and receive broadcast information broadcast by the second electronic device in the vicinity by referring to the operation of fig. 3 (g). Referring to fig. 5, the mobile phone receives broadcast information of a second electronic device (tablet, hua, earphone, speaker and smart screen) nearby, and displays a display identifier and a first volume corresponding to the tablet on the super terminal interface 500, that is, a tablet icon 501 and a first volume icon 502 surrounding the tablet icon 501. The display identifier and the first volume corresponding to the computer are displayed on the super terminal interface 500, namely, the computer icon 503 and the first volume icon 504 surrounding the computer icon 503 are displayed. The display identifier and the first volume corresponding to the earphone are displayed on the super terminal interface 500, that is, the earphone icon 505 and the first volume icon 506 surrounding the earphone icon 505 are displayed. The display identifier and the first volume corresponding to the sound box are displayed on the super terminal interface 500, that is, the sound box icon 507 and the first volume icon 508 surrounding the sound box icon 507 are displayed. The display identifier and the first volume corresponding to the smart screen are displayed on the super terminal interface 500, that is, the smart screen icon 509 and the first volume icon 510 surrounding the smart screen icon 509 are displayed. A handset icon 511 is also displayed on the super terminal interface 500, the handset icon 511 being located in the center of the super terminal interface 500. As shown in fig. 5, the device icons and the volume icons corresponding to the second electronic devices are respectively displayed in different display areas on the super terminal interface 500. For each second electronic device, the device icon and the volume icon are displayed close to each other.

Fig. 5 differs from fig. 3 (l) in that the first volume broadcast by each second electronic device is also displayed, i.e. the first volume icons surrounding each device icon are displayed. The volume size is represented as 100% by a length of the first volume icon surrounding the device icon by one revolution. The length of the first volume icon 502 is about half the circumference of the tablet icon 502, and the first volume icon 502 represents a first volume of 50% of the tablet. The length of the first volume icon 504 is three quarters of the way around the periphery of the computer icon 503, and the first volume icon 504 represents a first volume of 75% of the computer. The first volume icon 506 is half the length of the outer circumference of the earphone icon 505, and the first volume icon 506 represents that the first volume of the earphone is 50%. The length of the first volume icon 508 is just one turn around the periphery of the sound box icon 507, and the first volume icon 508 represents that the first volume of the sound box is 100%. The length of the first volume icon 510 is just one turn around the periphery of the smart screen icon 509, and the first volume icon 510 represents that the first volume of the smart screen is 100%.

As shown in fig. 5, if the first volume icon 508 and the first volume icon 510 each represent a volume of 100%, the line filling of the first volume icon 508 and the first volume icon 510 is the same. The first volume icon 502 and the first volume icon 506 each represent a volume of 50%, and the line fills of the first volume icon 502 and the first volume icon 506 are the same. The line fill of the first volume icon 504 is different from the line fill of the first volume icon 508, and the line fill of the first volume icon 504 is different from the line fill of the first volume icon 502.

In some embodiments, the volume icons may appear differently in color in addition to representing the fill pattern of the lines as shown in fig. 5. The line colors of the first volume icon 508 and the first volume icon 510 are red. The line colors of the first volume icon 502 and the first volume icon 506 are both green. The first volume icon 5041 line color is yellow.

In some embodiments, for a first volume with a volume percentage less than 50%, the color bar of the volume icon is green, representing a volume of appropriate size. For a first volume with a volume percentage of 50% to 80%, the color line of the volume icon is yellow, which represents a slightly higher volume, and may cause interference to the environment. For a first volume with a volume percentage greater than 80%, the color line of the volume icon is red, which represents that the volume is too large, and interference to the environment can occur.

It can be understood that the mobile phone receives the broadcast information of the second electronic device nearby, and can also display the received display identifier and the first volume broadcasted by the second electronic device on the super terminal card. The display identifier and the first volume corresponding to the second electronic device (or each second electronic device) are displayed on the super terminal card, and specifically, the display identifier and the first volume corresponding to the second electronic device may be displayed on the super terminal interface 500 with reference to fig. 5, which is not described herein.

Step S43: the first electronic device receives a first operation input by a user, wherein the first operation is used for setting a second volume of the second electronic device.

In the embodiment of the present application, in step S42, after the first electronic device displays the received first volumes broadcasted by the second electronic devices, the user may see the first volumes corresponding to the second electronic devices. The first electronic device also provides volume control capabilities that may provide a user with the ability to control the volume of the second electronic device. The user can set or adjust the volume of the second electronic device according to the self requirement by using the volume control capability, namely, the user can control the second electronic device to play the audio at the volume desired by the user through the volume control capability provided by the first electronic device. If the user inputs a first operation on the first electronic device, the first electronic device responds to the first operation to obtain a second volume, wherein the second volume is the volume used when the user wants the second electronic device to play audio, or the second electronic device wants the second electronic device to set the volume used when the audio is played according to the second volume, and the volume used when the audio is played is set to be the second volume.

It may be understood that, after the user sees that the volume of the second electronic device is the volume size corresponding to the first volume, the user wants to reset the volume of the second electronic device, and the user inputs a first operation, where the first operation is used to set the volume of the second electronic device from the volume size corresponding to the first volume to the volume size corresponding to the second volume.

Note that, if the first volume is the system volume, the second volume is also the system volume. If the first volume is a certain audio stream volume, the second volume is also the audio stream volume.

It should be noted that, before the second volume is validated, the actual volume of the second electronic device is still the first volume, and the second volume may be understood as the temporarily modified volume stored on the first electronic device. The user may input a first operation on the mobile phone, set the first volume H corresponding to the tablet to the second volume a, then modify the second volume a to the second volume B, and finally modify the second volume B to the second volume C, where the first electronic device may store the second volume a, the second volume B, and the second volume C locally, or store only the second volume C that is currently set. Before the second volume C is not validated (e.g., before the second volume C is transmitted to the tablet), the volume of the audio played by the tablet remains the first volume H.

In the embodiment of the present application, the second volume is effective, which is understood as that the second electronic device may play the audio according to the second volume. The time for the second volume to take effect may be when the first electronic device establishes a connection with the second electronic device, when the first electronic device transmits the second volume to the second electronic device, after the first electronic device transmits the second volume to the second electronic device, when the first electronic device transmits the second volume and the audio data to the second electronic device, after the first electronic device transmits the second volume and the audio data to the second electronic device, or after the first electronic device transmits the second volume to the second electronic device, before the first electronic device transmits the audio data to the second electronic device.

In the embodiment of the application, the first electronic device can respond to the first operation of the user in real time to obtain the second volume, and display the latest second volume currently set by the user in real time. And the latest second volume set by the user is displayed in real time, so that the user can know the second volume set by the second electronic equipment conveniently.

In this embodiment of the present application, the first electronic device may inform the user that the second volume is temporary and not valid, and may also inform the user that after the second volume of the second electronic device is set, if the second volume set in the preset time is not valid, the second volume will not be displayed, and resume displaying the actual volume corresponding to the second electronic device, that is, the first volume.

In one possible implementation manner, the first electronic device may inform the user that the second volume is temporary and inactive through a prompt, and may inform the user that the second volume set in the preset time is not active through a prompt, so that the second volume is not displayed, and the actual volume corresponding to the second electronic device, that is, the first volume, is restored to be displayed. The first electronic device may display the first volume and the second volume, and the first electronic device may display the first volume and the second volume on the interface. Wherein, the prompt box displays corresponding characters to play the role of prompting the user. The volume distinguishing mark is used for distinguishing the first volume from the second volume, and the user can distinguish the first volume from the second volume conveniently through the volume distinguishing mark, so that the user can know that the first volume is the actual volume, and the second volume is the non-effective temporary modified volume. The second volume is displayed in a manner different from the first volume display manner. If the first volume is displayed in the first display mode, the second volume is displayed in a second display mode different from the first display mode, and the first volume and the second volume can be conveniently distinguished by the user through different display modes (the first display mode and the second display mode), so that the user can know that the first volume is the actual volume and the second volume is the non-effective temporary modified volume. The presentation form of the prompt is not particularly limited in the embodiment of the present application.

In some embodiments, when the electronic device uses the volume distinguishing mark for the first time or uses a display mode with a different first volume from the second volume as a prompt, a prompt box is presented together to inform the user of the prompt meaning of the volume distinguishing mark or the different display mode, so that the user can see the volume distinguishing mark or the different display mode back down to know that the first volume is the actual volume and the second volume is the non-effective temporary modified volume.

In the embodiment of the application, the mode of setting the volume in the volume control capability provided to the user by the first electronic device includes a manual setting mode. In the manual setting mode, the first operation is used for directly setting the value of the second volume of the second electronic device according to the wish of a user, the first electronic device receives the first operation input by the user, and the second volume of the second electronic device is set according to the volume indicated by the first operation, namely, the specific value of the second volume is input by the user. The first operation in the manual setting mode may include sliding, clicking, long pressing, inputting by a keyboard, pressing a volume key of the first electronic device, and the like, and the specific form of the first operation is not particularly limited in this application.

Illustratively, taking the user entering the first operation on the super terminal interface 500 of fig. 5, the prompt appears as a display prompt box, and the user slides on the display screen of the mobile phone to set the second volume as an example.

The volume icons may be edited. The user may input a first operation, such as sliding the first volume icon 504, to slide the length of the first volume icon 504 to about half the circumference of the computer icon 503 to obtain a second volume icon 601 as shown in fig. 6 (a), in order to set the second volume of the computer. The second volume icon 601 in fig. 6 (a) is different from the first volume icon 504 in fig. 5 in that the length of the second volume icon 601 is shortened with respect to the length of the first volume icon 504, and the second volume icon 601 further includes an arrow 602. The arrow 602 represents that the current second volume icon 601 is in a volume setting state, i.e. the second volume represented by the second volume icon 601 is not yet valid, and still in an editing state, the second volume icon 601 may change its length according to the sliding of the user. As shown in fig. 6 (b), the user releases the touch control on the display screen of the mobile phone, and the mobile phone detects the user release sliding operation, and displays a second volume icon 603 on the mobile phone, where the second volume icon 603 represents that the second volume of the computer is 50%. The second volume icon 603 in fig. 6 (b) is different from the second volume icon 601 in fig. 6 (a) in that: the second volume icon 603 has no arrow 602, which represents that the second volume is currently set for the computer. As shown in fig. 6 (b), a prompt box 604 may also be displayed on the super terminal interface 500, and the prompt box 604 may be displayed near the second volume icon 603. The prompt box 604 displays "the second volume 50% is not validated", "the second volume 50% is a temporary modified volume", or "if the second volume 50% is not validated within ten seconds, the display of the first volume 75%" is resumed. The prompt "if the second volume 50% is not validated within ten seconds, the display of the first volume 75%" is resumed, that is, the preset time 10 seconds is represented by the fact that the second volume 50% is not validated, the second volume icon 603 will disappear, and the first volume icon 504 will be Zhou Xianshi outside the computer icon 503. That is, after the second volume is set as shown in fig. 6 (b), the second volume is not validated for ten seconds, and the super terminal interface 500 is refreshed as shown in fig. 5.

Illustratively, taking the user entering a first operation on the superterminal interface 500 of fig. 5, the prompt appears as a volume differentiation identifier, and the user enters a second volume via a keyboard as an example.

The first electronic device may provide a volume setting window and the first operation of the user input may include a plurality of sub-operations. As shown in fig. 7 (a), a computer icon 503 and a first volume icon 504 surrounding the periphery of the computer icon 503 are displayed on the mobile phone. The user wants to set the second volume of the computer, the user inputs a first operation including the user clicking on the computer icon 503, and the mobile phone displays a volume setting window 701 on the super terminal interface 500 in response to the user clicking on the computer icon 503. The volume setting window 701 displays the current volume of the computer, and the volume percentage of the current volume of the computer is 75% on the volume setting window 701. As shown in fig. 7 (b), the user input first operation further includes the user selecting "75" in the volume setting window 701, and after "75" in the volume setting window 701 is selected, displaying an input keyboard 702 on the super terminal interface 500. As shown in fig. 7 (c), the user inputting the first operation further includes the user inputting the numerals "5" and "0" through the input keypad 702, setting the second volume to 50%, and displaying the volume percentage to 50% on the volume setting window 701. If the user wants to modify the second volume, he selects "50" in the volume setting window 701 and proceeds to modify by inputting numbers through the input keyboard 702. If the user exits the keypad 702, the handset determines that the second volume is 50%. As shown in fig. 7 (d), a volume icon 703 is displayed on the handset. The volume icon 703 differs from the first volume icon 504 of fig. 5 in that: the volume icon 703 is augmented with a start identifier 704, a first volume end identifier 705, and a second volume end identifier 706. The start identifier 704 and the first volume end identifier 705 are used to indicate the start and end of the first volume, respectively. The length of the line between the start indicator 704 and the first volume end indicator 705 represents 75% of the first volume. The start identifier 704 and the second volume end identifier 706 are used to indicate the start and end of the second volume, respectively. The length of the line between the start indicator 704 and the second volume end indicator 706 represents 50% of the second volume.

The start identifier 704, the first volume end identifier 705, and the second volume end identifier 706 are all different and may be represented by different arrows, which are not specifically limited in this application.

Illustratively, taking the case that the user inputs the first operation on the super terminal interface 500 of fig. 5, the prompt is displayed in a display manner that the first volume is different from the second volume, and the user sets the second volume by pressing the volume key of the first electronic device.

As shown in fig. 8 (a), a computer icon 503 and a first volume icon 504 surrounding the periphery of the computer icon 503 are displayed on the mobile phone. The user wants to set the second volume of the computer, and the user inputs a first operation including the user pressing the computer icon 503 for a long time. The handset responds to the user long pressing of the computer icon 503 to display a volume progress bar 801 on the handset super terminal interface 500. The filled area on the volume progress bar 801 is three-quarters of the total area of the volume progress bar 801, representing that the computer is currently at 75% of the first volume. The user may press the volume "+" and "-" keys of the volume key 802 of the handset to set the second volume. As shown in fig. 8 (b), the user input first operation further includes the user pressing the volume "-" key, and adjusting the filling area on the volume progress bar 801 to be half of the entire area of the volume progress bar 801, that is, adjusting the volume to 50%, representing the currently set second volume to 50%. The user releases the pressing of the volume key 802, and the mobile phone detects the release of the pressing of the volume key 802 by the user, acquires the finally set volume "50%", and takes the volume "50%" as the second volume. As shown in fig. 8 (c), a second volume icon 803 is displayed according to the set second volume "50%", and the first volume icon 504 and the second volume icon 803 are displayed simultaneously near the computer icon 503. The first electronic device displays the first volume in the first display mode (first volume icon 504) and the second volume in the second display mode (second volume icon 803), and the first volume icon 504 is different from the respective lines. The first volume icon 504 is displayed separately from the second volume icon 803, i.e. the display of the second volume icon 803 does not overlap the display of the first volume icon 504, representing that the temporary modification of the volume does not overlap the actual volume of the second electronic device. The length of the line of the second volume icon 803 is about half the circumference of the computer icon 503, which represents 50% of the second volume.

The specific form of the first operation, the first volume icon, the second volume icon, and the display form of the prompt are not specifically limited.

In one possible implementation, the mode of volume setting in the volume control capability provided to the user by the first electronic device includes an automatic setting mode. In the automatic setting mode, the first electronic device receives a first operation input by a user, and sets the second volume according to a preset rule in response to the first operation. I.e. the specific value of the second volume is not directly entered by the user at the present time. The first operation in the automatic setting mode may include a swipe, a click, a double click, a long press or gesture (e.g., a circled gesture), and so forth.

In some embodiments, the first electronic device setting the second volume according to the preset rule in response to the first operation includes: the first electronic equipment responds to the first operation, the sound collecting equipment of the first electronic equipment is triggered to collect environmental sounds of the surrounding environment of the first electronic equipment, and the second volume is set according to the environmental sounds.

In the embodiment of the application, the user transmits the audio data on the first electronic device to the second electronic device, and the second electronic device plays the audio data, so that the first electronic device and the second electronic device are in the same environment. The first electronic device actively collects ambient sounds of the surrounding environment, and the collected ambient sounds are the ambient sounds of the surrounding environment of the second electronic device. Wherein the ambient sound may be expressed in decibels (dB).

In the embodiment of the application, the first electronic device sets the second volume according to the environmental sound collected by the sound collecting device. If the surrounding environment sounds very loud, the collected decibel of the surrounding sound is 85dB, the first electronic device can set a larger second volume, and the second electronic device plays the audio by using the larger second volume so as to ensure that the user hears the audio. If the surrounding environment sound is very small, the collected decibel of the environment sound is 15dB, and the first electronic equipment can set smaller second volume, so that the second volume used by the second electronic equipment can keep comfortable volume with the environment sound, and the hearing experience of a user is improved. Illustratively, the first electronic device detects that the environmental sound of the current environment is 85dB, in order to ensure that the user can hear the audio, the second sound volume may be set to be larger than the sound volume of the environmental sound, for example, 90dB, and the second sound volume may be set to 85% according to the conversion between the sound volume percentage and the decibel.

In some embodiments, the volume levels of different environmental sounds may be set to different levels in advance, and corresponding second volumes may be set to different levels. As shown in table 3 below:

TABLE 3 Table 3

Volume of ambient sound	Grade	Second volume
			0dB
	0	15dB or less or 10%
			15dB or less	1	30dB or 20%
30dB
		2	40dB or 30%
40dB
		3	60dB or 40%

		9	120dB or 100%

Illustratively, taking the case that the user inputs the first operation on the super terminal interface 500 of fig. 5, the prompt is displayed in a display manner that the first volume is different from the second volume, and the user presses the icon for a long time to set the second volume.

As shown in fig. 9 (a), a computer icon 503 and a first volume icon 504 surrounding the periphery of the computer icon 503 are displayed on the mobile phone. The user may input a first operation, such as the user double clicking on the computer icon 503, in order to set the second volume of the computer. As shown in fig. 9 (b), the handset triggers a sound collection device (e.g., microphone) to collect ambient sounds of the surrounding environment in response to the user double clicking the computer icon 503. A sound picking state identifier 901 is displayed on the mobile phone, and the sound picking state identifier 901 indicates that the current mobile phone is in a sound picking state. As shown in fig. 9 (c), the volume of the ambient sound of the current surrounding environment obtained by the mobile phone is 60dB, and the mobile phone sets the second volume to 50% according to table 3. The volume progress bar 902 is displayed on the mobile phone, and the filling area on the volume progress bar 902 occupies half of the whole area of the volume progress bar 902, which represents that the current second volume is 50%. The first volume is represented by a first volume chart 504 and the second volume is represented by a volume progress bar 902. The first volume chart 504 and the volume bar 902 are differently represented, the first volume chart 504 expresses a first volume size in terms of a length of a line around the periphery of the computer icon 503, and the volume bar 902 expresses a second volume size in terms of a percentage of the filled area to the entire progress bar area.

In some embodiments, the first electronic device setting the second volume according to the preset rule in response to the first operation includes: the first electronic equipment responds to the first operation to determine a second electronic equipment indicated by the first operation, acquires a volume record of the second electronic equipment, and sets a second volume according to the volume record, wherein the volume record is used for recording the effective second volume which is set by the second electronic equipment in the past. For example, the first electronic device may obtain the volume (e.g., 10%) with the largest number of recordings in the volume recording, and set the volume with the largest number of recordings as the current second volume. The first electronic device may also set the volume of the latest recording (e.g., 10%) of the volume recordings to the current second volume.

In this embodiment of the present application, the first electronic device may acquire the device identifier of each second electronic device and the second volume that is effective by the device identifier, and store the device identifier of the second electronic device in association with the second volume that is effective by the device identifier. For example, for a certain second electronic device, the device identifier of the second electronic device is a, the user sets the second volume to a for the second electronic device, then sets the second volume to b, and the second volume b is effective. At the next time, the user sets the second volume to c for the second electronic device, and the second volume c is effective. The first electronic device may record a volume record of the second electronic device as: the device identifier a and its previously set effective second volume include a second volume b and a second volume c. The first electronic device may further record a time for each second volume to be validated, for example, the second volume b is validated at time T0, the second volume c is validated at time T1, and the mobile phone may determine the latest recorded volume according to the validation time.

Illustratively, taking the user inputting the first operation on the super terminal interface 500 of fig. 5, the prompt appears as a prompt box, and the user inputs the circling gesture to set the second volume as an example.

As shown in fig. 10 (a), a computer icon 503 and a first volume icon 504 surrounding the periphery of the computer icon 503 are displayed on the mobile phone. The user may input a first operation, such as the user sliding one turn around the outer circumference of the computer icon 503, in order to set the second volume of the computer. As shown in fig. 10 (b), in response to the user sliding one turn around the computer icon 503, the mobile phone obtains the volume record corresponding to the computer icon 503, where the second volume of the latest record in the volume record is 50%. The handset sets the newly recorded second volume of 50% to the second volume. The mobile phone may also display a prompt window 102, where "whether to set to 50% of the last volume" and "yes" and "no" options are displayed in the prompt window 102. If the user clicks the "no" option, the user may select to manually set, or the mobile phone sets the second volume according to other rules, e.g., the mobile phone sets the volume with the largest number of recordings in the volume record as the second volume. If the user clicks the "yes" option, the mobile phone responds to the user clicking the "yes" option to set the second volume of the computer to 50%. As shown in fig. 10 (c), a prompt box 103 "the second volume 50%" is displayed on the mobile phone, and the prompt box 103 may also display "not yet valid".

In some embodiments, the mode of volume setting in the volume control capability provided to the user by the first electronic device comprises a global setting mode. In the global setting mode, the first electronic device may automatically set the same second volume for all the second electronic devices. The first operation in the global setting mode may include triggering a global setting control, inputting a specific gesture, and the like, and the specific expression form of the first operation is not specifically limited in this application.

The user may trigger the global setting control, and the first electronic device may set the second volume for all the second electronic devices corresponding to the broadcast information received by the first electronic device in response to the user triggering the global setting control, which may also be understood as setting the second volume for all the second electronic devices (such as a tablet, a hua computer, an earphone, a sound box, and a smart screen) displayed on the super terminal interface 500. For example, when the first electronic device receives the first volume and the device identifier of the broadcast by the device a and the device B, all the second electronic devices corresponding to the received broadcast information are referred to as the device a and the device B. The second sound volume may be obtained by setting in the manual setting mode or the automatic setting mode described above. In other words, in the global setting mode, the first operation input by the user sets the second volume not for a certain second electronic device but for all the second electronic devices corresponding to the broadcast information received by the first electronic device.

In the embodiment of the present application, in the global setting mode, the first electronic device automatically sets the same second volume a for all the second electronic devices corresponding to the broadcast information received by the first electronic device. After the second volumes a are set by the plurality of second electronic devices, for a certain second electronic device, the time for which the second volume is valid may refer to the time for which the second volume is valid, which is not described herein.

Illustratively, the user manually sets the second volume in the global setting mode. Referring to fig. 11 (a), the super terminal interface 500 further includes a global setting control 111, and the form of presentation of the global setting control 111 on the interface is not specifically limited in this application. The user may input the first operation, which the user wants to set the second volume of the second electronic device. As in fig. 11 (a), the first operation of the user input may include the user clicking on the global settings control 111. After the user clicks the global setting control 111, the user may set the second volume in the manner shown in fig. 6 (a). The first operation of user input may further include the user adjusting the volume icon of any of the second electronic devices, and the first operation of user input may further include the user sliding the first volume icon 504, and sliding the length of the first volume icon 504 to about half of the periphery of the computer icon 503, so as to obtain a second volume icon 110 as shown in fig. 11 (b), where the length of the second volume icon 110 is about half of the periphery of the computer icon 503, which represents that the second volume is 50%. After the user has set the second volume, as shown in fig. 11 (b), window 112 "whether the second volume is set to 50%" and "yes" and "no" options may be displayed on the handset. The display window 112 may also display "whether the second volume is set to 50% globally", where the content displayed by the display window 112 is used to prompt the user to set the second volume currently, and may also prompt the user to set the second volume currently to be set globally. If the user clicks the "no" option, the second volume is not set for all second electronic devices (e.g., tablet, hua, computer, earphone, speaker, and smart screen) by 50%. If the user clicks the "yes" option, it is confirmed that the second volume of all the second electronic devices (tablet, chinese computer, earphone, speaker and smart screen) is set to 50%. As shown in fig. 11 (c), the handset displays a volume progress bar 113, the volume progress bar 113 identifying that the second volume is 50%, i.e., that the second volume of all second electronic devices currently displayed on the super terminal interface 500 is 50%. If the second volume of all the second electronic devices is effective, all the second electronic devices play the audio by using 50% of the second volume.

In some embodiments, the user may set the second volume in the manner shown in fig. 7 (a) to 7 (c), and after the user clicks the global setting control 111, the first operation input by the user may further include the user clicking a device icon of any of the second electronic devices. As shown in fig. 7 (a), the first operation of the user input by clicking the computer icon 503 may further include the user entering "50" through the input method keyboard after the user selects "75" in the volume setting window, and setting the second volume to be 50%. The mobile phone obtains the second volume 50% set by the user, and sets the second volumes of all the second electronic devices to 50%. In some embodiments, the user may set the second volume in the manner shown in fig. 8 (a) to 8 (b), and after the user clicks the global setting control 111, the first operation input by the user may further include the user pressing a device icon of any of the second electronic devices for a long time. As shown in fig. 8 (a), the user pressing the computer icon 503 for a long time may further include the user pressing the volume "-" to adjust the volume to 50%, the mobile phone obtains the second volume set by the user to 50%, and the second volumes of all the second electronic devices to 50%. The user may set the second volume through any of the manual setting modes described above, which is not particularly limited in this application.

In some embodiments, the global setting control may aggregate the functions provided by the automatic setting mode, that is, the first electronic device may set the second volume using the automatic setting mode after the user clicks the global setting control.

Illustratively, the mobile phone sets the second volume according to the environmental sound. As shown in fig. 11 (a), the user input first operation may include the user clicking on the global setting control 111, and after the user clicks on the global setting control 111, the user may set the second volume in the manner shown in fig. 9 (a) to 9 (b). The user entering the first operation may further include the user double clicking on a device icon of any of the second electronic devices, and the mobile phone may display the sound production status identifier 901. The mobile phone obtains the environmental sound of the current surrounding environment, and the mobile phone automatically sets the second sound volume to 50% according to the volume of the obtained environmental sound according to the above table 3. As shown in fig. 11 (d), the mobile phone displays a prompt box 114 "globally sets the second volume to 50%", informing the user that the second volumes of all the second electronic devices are currently set to 50%.

In some embodiments, the mobile phone sets the second volume according to volume records of all the second electronic devices. The mobile phone obtains the volume records of all the second electronic devices, obtains the volume with the largest record number or the volume which is recorded most recently from the volume records, and sets the volume with the largest record number or the volume which is recorded most recently as the second volume. For example, all the second electronic devices include device a and device B, where the number of times of recording the volume a in the volume record of device a is 5 times, the number of times of recording the volume B in the volume record of device B is 4 times, the number of times of recording the volume a in the volume record of device B is 2 times, and the number of times of recording the volume B is 4 times, so that the volume B with the largest recording times can be obtained.

As shown in fig. 12 (a), the user slides one turn clockwise along the device icons (tablet icon 501, computer icon 503, earphone icon 505, sound box icon 507, and smart screen icon 509) of all the second electronic devices, and the mobile phone detects a circling gesture entered by the user. And responding to the circling gesture of the user, the mobile phone acquires volume records of all the second electronic equipment, and the volume with the largest occurrence number can be obtained from the volume records to be 50%, so that 50% of the volume with the largest occurrence number can be determined as the second volume. As shown in fig. 12 (b), the mobile phone displays a prompt box 121 "whether the second volume is set to 50%" globally and "yes" option and "no" option. If the user clicks the "no" option, the handset may provide the user with a manual setting mode or an automatic device mode for the user to continue setting the second volume. The user clicks the yes option and the second volume of the second electronic device is globally set to 50%. The user determines to set the second volume of all second electronic devices to 50%. As shown in fig. 12 (c), a corresponding second volume icon 121 is displayed on each second electronic device, and the second volume icon 121 identifies that the second volume is 50%. The mobile phone also displays a prompt box 122, which directs the user to establish a connection, for example, if the second volume is not yet in effect. It will be appreciated that if the second volume is not valid within the preset time, the interface shown in fig. 12 (a) is restored to be displayed.

In some embodiments, after the second volumes of all the second electronic devices are globally set, the second volumes may be displayed separately from the first volumes of the respective first electronic devices. As shown in fig. 13, a tablet icon 501, a first volume icon 502 surrounding the tablet icon 501, and a second volume icon 131 are displayed on the mobile phone, the second volume icon 131 indicating that the second volume of the current tablet is 50%. The mobile phone displays a computer icon 503, a first volume icon 504 surrounding the computer icon 503, and a second volume icon 132, wherein the second volume icon 132 indicates that the second volume of the current computer is 50%. An earphone icon 505, a first volume icon 506 surrounding the earphone icon 505, and a second volume icon 133 are displayed on the mobile phone, the second volume icon 133 indicating that the second volume of the current earphone is 50%. The mobile phone displays a sound box icon 507, a first volume icon 508 surrounding the sound box icon 507, and a second volume icon 134, the second volume icon 134 indicating that the second volume of the current sound box is 50%. The mobile phone displays a smart screen icon 509, a first volume icon 510 surrounding the smart screen icon 509, and a second volume icon 135, the second volume icon 135 indicating that the second volume of the current smart screen is 50%. The mobile phone also displays a prompt 136, and the prompt 136 displays "the second volume is not yet effective, and drags to the local to establish connection or initiate task connection", so as to instruct the user to drag the second electronic device icon to the mobile phone icon 511 to establish connection. Step S44: the first electronic device receives a second operation of the user input.

In this embodiment of the present application, after the user sets the second volume in step S43, the user inputs a second operation on the first electronic device, where the second operation is used to trigger the first electronic device to establish a connection with the second electronic device for transmitting the second volume and the audio data, trigger the first electronic device to transmit the second volume to the second electronic device, and trigger the first electronic device to transmit the audio data to the second electronic device.

Illustratively, after the user sets the second volume to 50% as shown in fig. 8 (c), the user wants to transmit the second volume and the audio data to the second electronic device as shown in fig. 14 (a), and the user may input a second operation, which may include the user performing a sliding operation on the super terminal interface 500, such as the user dragging the computer icon 503 to the location of the cell phone icon 511. As shown in fig. 14 (b), after the computer icon 503 contacts the mobile phone icon 511, the computer icon 503 and the mobile phone icon 511 are highlighted, and the computer icon is displayed as if the computer and the mobile phone are connected. In some embodiments, after the mobile phone establishes a connection with the computer, as shown in fig. 14 (b), the first volume icon 504 surrounding the computer icon 503 disappears, and only the volume icon 141 surrounding the computer icon 503 is displayed. Fig. 14 (b) differs from fig. 8 (c) in that: the computer icon 503 is adjacent to the mobile phone icon 511, the first volume icon 504 surrounding the computer icon 503 disappears, and only the volume icon 141 surrounding the computer icon 503 is displayed. The display manner of the volume icon 141 may be similar to that of the first volume icon 504, for example, the line shapes or fills of the volume icon 141 and the first volume icon 504 in fig. 14 (b) are the same, except that the lengths of the lines of the volume icon 141 and the first volume icon 504 are different. The volume icon 141 indicates that the volume of the second electronic device, i.e., the computer, is 50% at this time, i.e., the actual volume of the current second electronic device is 50%.

Illustratively, after the user has set the second volume of all the second electronic devices to 50% as shown in fig. 13, the user clicks the back key 1501 as shown in fig. 15 (a). As shown in fig. 15 (b), the control center interface 30 is displayed on the mobile phone, and the tablet icon 501 and the second volume icon 131 are displayed on the super terminal card 304, and the second volume icon 131 indicates that the second volume of the current tablet is 50%. A computer icon 503 and a second volume icon 132 are also displayed, the second volume icon 132 indicating that the second volume of the current tablet is 50%. An earphone icon 505 and a second volume icon 133 are also displayed, the second volume icon 133 indicating that the second volume of the current tablet is 50%. A speaker icon 507 is also displayed, as well as a second volume icon 154, the second volume icon 134 indicating that the second volume of the current tablet is 50%. A smart screen icon 509 is also displayed, as well as a second volume icon 155, the second volume icon 135 indicating that the second volume of the current tablet is 50%. As shown in fig. 15 (c), the user wants to send the second volume and audio data to the computer, the user can input a second operation on the super terminal card 304, the user inputs the second operation, for example, the user clicks the computer icon 503, the mobile phone responds to the user clicking the computer icon 503 to establish the connection between the computer and the mobile phone, and then the second volume 50% of the computer will be effective. As shown in fig. 15 (d), the mobile phone and the computer are being connected, and the second volume set by the computer is 50% effective. The volume icon 151 is displayed under the computer icon 503, and the volume icon 151 indicates that the volume of the computer is 50% after the computer is set, i.e. the actual volume of the computer is 50% at the current time.

In some embodiments, the user may be prompted to make a volume setting if the second electronic device is louder, e.g., above a certain percentage, alert value, threshold, or above the current volume percentage of the first electronic device, before the first electronic device establishes its connection with the second electronic device for transmitting the second volume and audio data.

For example, if the user does not set the second volume of the second electronic device, and before the first electronic device establishes a connection between the first electronic device and the second electronic device for transmitting the second volume and the audio data, the first electronic device detects that the volume of the second electronic device (i.e., the first volume) is higher than a certain percentage, an alert value, a threshold, or a volume percentage higher than that of the current first electronic device, the user may be prompted to set the volume. As shown in fig. 16 (a), when the user does not set the second volume for the computer, and the user drags the computer icon 503 to be close to the mobile phone icon 511, the user can drag the computer icon 503 to be close to the mobile phone icon 511 by clicking the "no" option, and displaying the prompt box 161 "whether the second volume needs to be set", "yes" option and "no" option on the mobile phone. If the user clicks the "yes" option, the user may set the second volume with reference to the automatic setting mode or the manual setting mode described above.

In some embodiments, the user sets the second volume of the second electronic device, and before the first electronic device establishes a connection between the first electronic device and the second electronic device for transmitting the second volume and the audio data, the first electronic device detects that the volume of the second electronic device (i.e., the second volume) is higher than a certain percentage, an alert value, a threshold value, or a volume percentage higher than the current first electronic device, and may prompt the user to perform the volume setting. As shown in fig. 16 (b), the user sets a second volume for the computer, and the user can drag the computer icon 503 to the position of the mobile phone icon 511, the mobile phone returns the computer icon 503 to the original position, and a prompt box 162 is displayed, and if the "current volume is too large", "yes" option and "no" option are required to be set, if the user clicks the "no" option, the mobile phone drags the computer icon 503 to the position of the mobile phone icon 511 is displayed in the prompt box 162. If the user clicks the "yes" option, the user may set the second volume with reference to the automatic setting mode or the manual setting mode described above.

In some embodiments, after the second volume setting is completed, immediately before the second volume is validated, immediately before the first electronic device transmits the second volume to the second electronic device, or immediately before the first electronic device establishes a connection with the second electronic device, a prompt may be displayed to confirm whether the second volume is currently set. If the user confirms, the first electronic device transmits the second volume, the audio data or the second volume and the audio data to the second electronic device.

Illustratively, the user sets the second volume as shown in fig. 12 (c), and drags the computer icon 503 to the cell phone icon 511. As shown in fig. 17, a prompt box 171 may also be displayed on the mobile phone, and a "whether to confirm setting the second volume to 50%," yes "option and" no "option are displayed in the prompt box 171. The user clicks the yes option and the steps may continue, such as the first electronic device continuing to establish its connection with the second electronic device, the first electronic device continuing to transmit the second volume to the second electronic device. If the user clicks the "no" option, the user may set the volume with reference to the automatic setting mode or the manual setting mode described above.

In some embodiments, after the user sets the second volume and clicks on the computer icon 503, the prompt box 171 may be displayed on the super terminal card 304 as shown in fig. 15 (c).

It should be noted that, the method is not limited to the user inputting the first operation and the second operation on the super terminal interface 500, and the user may also input the first operation and the second operation on the super terminal card 304, that is, the super terminal card 304 shown in fig. 15 (b) may display each element or control with reference to the super terminal interface 500, for example, including the display identifier of the second electronic device, the first volume icon, the second volume icon, the global setting control, and the prompt, which are not limited in this application.

It should be noted that, the first electronic device may further provide a volume setting interface, where the volume setting interface may be displayed with reference to the above-mentioned super terminal interface 500, and each element or control may be displayed on the volume setting interface with reference to the super terminal interface 500 or the super terminal card 304, for example, including a display identifier of the second electronic device, a first volume icon, a second volume icon, a global setting control, and the above-mentioned prompt. The present application is not particularly limited thereto. For example, the user clicks on a setup option on the handset to enter the volume setting interface.

Step S45: the first electronic device establishes a connection with the second electronic device for transmitting second volume and audio data.

In the embodiment of the present application, in step S44, the first electronic device detects a second operation of the user, and the first electronic device establishes a connection with the second electronic device for transmitting the second volume and the audio data in response to the second operation. The connection may be a wireless communication connection, for example, a Wi-Fi connection, a bluetooth connection, a P2P connection, an NFC connection, or a communication connection based on a cellular network, or the connection may be a wired connection, for example, a data line or dock device may be used to connect a mobile phone and a notebook computer, which is not limited in this embodiment of the present application.

For example, an NFC chip or an electronic tag may be provided on the notebook computer, and device information of the notebook computer, such as a MAC address of the notebook computer, etc., may be stored in the NFC chip or the electronic tag. Furthermore, after the NFC function of the mobile phone is started, the equipment information of the notebook computer can be obtained by approaching or touching the NFC chip or the electronic tag on the notebook computer. Thus, the mobile phone can establish Bluetooth connection, wi-Fi connection or P2P connection with the notebook computer according to the equipment information.

For another example, a preset two-dimensional code may be displayed on the notebook computer, where the two-dimensional code includes equipment information of the notebook computer. Then, the mobile phone can also acquire the equipment information of the notebook computer by scanning the two-dimensional code on the notebook computer. Thus, the mobile phone can establish Bluetooth connection, wi-Fi connection or P2P connection with the notebook computer according to the equipment information.

Of course, the user can also use the mobile phone to create a Wi-Fi hot spot, and access the notebook computer into the Wi-Fi hot spot created by the mobile phone, so that the connection between the mobile phone and the notebook computer is established.

Step S46: the first electronic device transmits the second volume to the second electronic device.

In the embodiment of the application, the first electronic device transmits the second volume to the second electronic device based on the connection between the first electronic device and the second electronic device for transmitting the second volume. For example, the first electronic device may send a volume setting request to the second electronic device and send a second volume.

In the embodiment of the present application, as shown in fig. 17, the user confirms that the second volume is set to 50%, and then the second volume is 50% effective. Or when the first electronic device and the second electronic device are connected, as shown in fig. 14 (b), the second volume is 50% effective when the computer icon 503 with the second volume is dragged to the mobile phone icon 511. Or as in fig. 15 (c), the user clicks on the computer icon 503, and the set second volume is validated.

Step S47: the second electronic device sets its volume to a second volume.

In the embodiment of the present application, the second electronic device may call a function setVolume (AudioVolumeType volumeType, int volume) to set the second volume. After the second volume setting is completed, the second electronic device may respond to the volume setting request sent by the first electronic device, and reply to the completion of the volume setting.

Step S48: the first electronic device transmits audio data to the second electronic device.

In the embodiment of the application, the first electronic device transmits the audio data to the second electronic device based on the connection between the first electronic device and the second electronic device for transmitting the audio data.

In some embodiments, if the first electronic device transmits the second volume and the audio data to the second electronic device at the same time, the second electronic device needs to play the audio data after the second volume is set.

In some embodiments, after receiving the information that the volume is set up and returned by the second electronic device, the first electronic device may further display a confirmation message, for example, the first electronic device displays "whether to confirm that the second volume is 50%" or "whether to confirm that the audio is played at 50% volume", and if the user selects confirmation, the first electronic device retransmits the audio data to the second electronic device.

In the embodiment of the present application, the step 46 and the step S48 may be performed simultaneously, or the step 46 is performed before the step S48 is performed, or the step 48 is performed after the step S46 is performed, which is not specifically limited in the embodiment of the present application.

In some embodiments, the first electronic device transmits the second volume to the second electronic device with audio data of the first electronic device. I.e. the first electronic device may transmit the second volume and the audio data of the first electronic device based on the same communication channel established in step S45.

Step S49: the second electronic device receives the audio data and plays the audio data using a second volume.

In the embodiment of the present application, in step S47, the second electronic device has set its current volume to the second volume, and the second electronic device will play the audio data using the second volume. As shown in fig. 18, the user sets the volume of the computer to 50%, and the volume progress bar 181 is displayed on the computer, and the current volume is displayed on the volume progress bar 181 to 50%. After the mobile phone transmits the audio data to the computer, the computer plays the audio data at 50% volume.

In some embodiments, the first electronic device includes a "safe mode" in the volume control capability provided to the user. In the "safe mode", the operation input by the user may enable the first electronic device to continuously set the second volume and continuously transmit the second volume to the second electronic device until the transmitted second volume meets the first preset condition. The first electronic device may transmit a third volume to the second electronic device in response to the operation input by the user, the third volume being less than the second volume; continuously increasing the third volume, and transmitting the adjusted third volume to the second electronic device until the adjusted third volume reaches the second volume or reaches a first preset condition, wherein the first preset condition is that the volume of the audio played by the second electronic device collected by the first electronic device meets the actual volume which reaches the second volume and is determined by the first electronic device. For example, the first preset condition is reached until the first electronic device detects that the volume (such as decibel) of the audio played by the second electronic device is appropriate, or the volume obtained after the second electronic device adjusts the volume of the audio reaches the second volume (such as percentage).

That is, in the "safe mode", the second volume may be set by one step and the first electronic device may be triggered to transmit the second volume and audio data to the second electronic device. The first operation and the second operation may be combined into one operation, or the first operation has a function of the second operation, and the second operation is an optional operation.

For example, referring to fig. 19 (a), the user input operation may include the user pressing the switch key 191 and the computer icon 503, thereby triggering the security mode. The handset detects that the user triggers the secure mode, as shown in fig. 19 (b), establishes a connection with the second electronic device and transmits the third volume 10% and audio data to the computer. The computer receives the third volume of 10%, and the volume is set to 10%. Hua is a computer that plays audio data at 10% volume. The mobile phone detects that the decibel of the audio played by the computer is 5dB, and the preset decibel of the audio is not 10dB. As shown in fig. 19 (c), the mobile phone adjusts the third volume according to the step value of 10%, the mobile phone increases the third volume by 10% by the step value of 10%, the 20% volume is obtained, and the mobile phone continues to transmit the second volume of 20% and the audio data to the computer. The computer receives the second sound volume of 20% and sets the sound volume of 20%. The mobile phone detects that the decibel of the audio data played by the computer is 10dB, and reaches the preset decibel of 10dB, and the mobile phone stops continuously transmitting the second volume to the computer.

In some embodiments, in the secure mode, the first electronic device transmits the secure mode instruction and the third volume to the second electronic device. The second electronic equipment receives the safety mode instruction, and continuously adjusts the third volume in response to the safety mode instruction until the first electronic equipment detects that the volume of the audio played by the second electronic equipment is proper, or until the third volume adjusted by the second electronic equipment reaches the second volume. When the first electronic equipment detects that the volume set by the second electronic equipment reaches a first preset condition, the first electronic equipment sends a stop instruction to the second electronic equipment, the second electronic equipment stops setting the volume, and audio is played at the volume reaching the preset condition.

In the embodiment of the application, the current volume of the electronic equipment for receiving the audio data is displayed, the volume control capability of the electronic equipment for receiving the audio data is provided, so that after the audio data is transmitted to the electronic equipment for receiving the audio data, the electronic equipment for receiving the audio data can play the audio data at a proper volume, the condition of harshness and interference caused by sound circulation is avoided, and brand new experience is brought to audio sharing.

Referring to fig. 20, fig. 20 is a schematic structural diagram of a volume control device according to an embodiment of the present application. The volume control device 400 may be used to perform some or all of the steps of the method described in fig. 4 to 19 (c), and is specifically described with reference to fig. 4 to 19 (c), which are not repeated herein. The volume control device 400 may include:

the first receiving unit 401 is configured to obtain a first volume of a second electronic device, and display the first volume, where the first electronic device does not currently transmit audio data to the second electronic device.
