Description

Technical Field

[0001] Embodiments of the present application relate to the field of volume adjustment, and more particularly to a method and a terminal for adjusting the volume of a terminal. Background Art

[0002] As the functions of terminal devices continue to increase, terminal devices are widely used. In the prior art, the volume of the incoming call ringtone or vibration, media sound, receiver and loudspeaker of the terminal device needs to be manually set by the user. Whether it is the incoming call reminder volume or the video / music / call volume, the existing terminal devices all use the user to control the volume through the physical volume key or the screen virtual button (volume bar).

[0003] In terms of incoming call reminder sounds, users can choose from two modes: "ringing" or "silent". When the user uses the "ringing" mode by default, the ringing may suddenly ring in meetings or quiet occasions, causing embarrassing situations; if the user uses the "silent / do not disturb" mode on a daily basis, there may be a situation where the call / message cannot be answered in time; when playing videos / music, although the phone uses the silent mode for incoming calls, it may still record the last playback volume when playing content, causing explosive sounds in a quiet environment and causing embarrassment; during a call, in a noisy environment, the volume often needs to be manually turned up to hear the other party's voice more clearly.

[0004] When the user is in different scenarios, the user needs to manually adjust various volumes of the terminal according to the various scenarios, which is cumbersome and inconvenient. Summary of the invention

[0059] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0060] In the description of the embodiments of the present application, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present application.

[0061] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0062] In the prior art, the volume of the incoming call ringtone or vibration, media sound, receiver and loudspeaker of the terminal device all need to be manually set by the user. Whether it is the incoming call reminder volume or the video / music / call volume, the existing terminal devices all use the user to control the volume through the physical volume key or the screen virtual button (volume bar). However, it is cumbersome to adjust the volume manually multiple times, and the adjustment is not timely enough. Therefore, the embodiment of the present application provides a method for adjusting the terminal volume, which can automatically adjust the terminal volume.

[0063] It is understandable that the terminal described in the embodiment of the present application can be a mobile phone or an electronic watch with a sound playing function, etc., which is not limited here, and the terminal described below will not be repeated. There are two main types of sounds played by the terminal: reminder sound and content sound. Reminder sound is mainly a sound with the main purpose of reminder, such as ringtone, key feedback sound, etc., which is not limited here; while content sound is mainly a sound with the main purpose of conveying information, such as video soundtrack, music, voice message, call, etc., which is not limited here. Therefore, based on the difference between reminder sound and content sound, when adjusting the volume of the sound, the terminal needs to first distinguish whether the current external sound is a reminder sound or a content sound. When the terminal plays the sound, it can determine whether the current external sound is a reminder sound or a content sound according to its own application. For example, if the application that currently needs to play the sound is an alarm clock, it can be determined that the current external sound is a reminder sound. If the application that currently needs to play the sound is a video player, it can be determined that the current external sound is a content sound. The reminder sound is generally preset, and the content sound is generally the sound carried by the application.

[0064] The following uses the reminder tone as an example to explain the process of adjusting the terminal volume. Figure 1 As shown, the specific steps are as follows:

[0065] 101. Periodically check whether the terminal is in a stable state.

[0066] The terminal can periodically detect through multiple sensors on the terminal to determine whether the terminal is in a stable state. It is understandable that the periodic detection can be set according to the actual situation. Since the terminal may change from position A to position B / environment / state within a period of time, the result of the detection at A and the matching feedback form may no longer be applicable to the occasion where B is located. Therefore, if the power consumption allows, periodic detection needs to be set.

[0067] The detection period can be set to perform a detection for 5 seconds every 5 seconds or a detection for 6 seconds every 8 seconds. The specific detection is not limited here. It is preferred to perform a detection for 5 seconds every 5 seconds. If in the process of a periodic detection, the information collected by the sensor on the terminal finds that the ambient sound type of the environment in which the terminal is located or the motion state of the terminal has changed, it can be considered that the terminal is not in a stable state. For example, if in a detection process lasting 5 seconds, the data collected in the 3rd second is compared with the data collected in the 4th second, and it is found that the ambient sound type of the environment in which the terminal is located or the motion state of the terminal has changed, it can be considered that the terminal is not in a stable state.

[0068] 102. Determine an ambient sound type of an environment in which the terminal is located and determine a spatial scene type of an environment in which the terminal is located.

[0069] When the terminal is in a stable state, determine the type of ambient sound of the environment in which the terminal is located and determine the type of spatial scene of the environment in which the terminal is located. Specifically, during a period of detection, if it is found that the type of ambient sound in which the terminal is located and the motion state of the terminal have not changed, it can be considered that the terminal is in a stable state in this detection cycle. At this time, the type of ambient sound in the environment in which the terminal is located can be determined according to the audio acquisition module on the terminal, and the type of spatial scene in the environment in which the terminal is located can be determined according to the audio acquisition module or other sensors on the terminal. It can be understood that the audio acquisition module can be a microphone or a device for collecting sound, which is not specifically limited here. The other sensors can be acceleration sensors, gyroscopes, distance sensors, light sensors, etc., which are not specifically limited here.

[0070] The ambient sound type refers to the type of sound in the environment where the terminal is located. The ambient sound type can be determined based on the collected ambient sound, such as noisy environment, quiet environment, etc., which is not limited here. The spatial scene type refers to the specific scene with spatial significance where the terminal is located, such as a conference room, a living room, etc., which is not limited here.

[0071] 103. Determine a prompt mode of the terminal according to the ambient sound type and the spatial scene type.

[0072] The terminal can determine the prompt mode of the terminal according to the ambient sound type and the spatial scene type determined in a stable state. The prompt mode is mainly used to determine the presentation form of the prompt sound and can be pre-set. The prompt mode can be one of the do not disturb mode, gentle disturbance mode or reminder mode.

[0073] Specifically, it can be pre-set that when the ambient sound collected by the audio acquisition module is greater than or equal to a preset sound pressure amplitude, the ambient sound type is determined to be a noisy environment dominated by ambient sound, and the spatial scene type is outdoor, then the prompt mode is determined to be a reminder mode. When the ambient sound collected by the audio acquisition module is less than the preset sound pressure amplitude, the ambient sound type is determined to be a quiet environment, and the spatial scene type is indoors, then the prompt mode is determined to be the do not disturb mode. It can be understood that the preset sound pressure amplitude can be 50dB or 60dB, which is not specifically limited here, and the preset sound pressure amplitude can be modified accordingly according to actual conditions.

[0074] 104. The control terminal performs a reminder operation according to the reminder mode.

[0075] When the terminal determines that the sound to be played externally is a prompt sound, the terminal performs a prompt operation according to the prompt mode determined in a stable state, so as to implement different prompt operations according to specific circumstances.

[0076] Specifically, when the terminal determines that the prompt mode is the do not disturb mode, the sound playing device is controlled not to play the sound, and the vibration device is controlled to perform the vibration operation, and the vibration gradually increases from weak to strong; when the terminal determines that the prompt mode is the light disturbance mode, the sound playing device is controlled to play the sound (ringtone) from weak to strong, and the vibration device is controlled to perform a strong vibration reminder; when the terminal determines that the prompt mode is the reminder mode, the sound playing device is controlled to play a loud sound (ringtone) reminder, and the vibration device is controlled to perform a strong vibration reminder.

[0077] In the embodiment of the present application, when a prompt sound needs to be played, the prompt mode of the terminal is determined by determining the ambient sound type, and the volume of the terminal's external sound can be automatically adjusted according to different prompt modes.

[0078] The present application embodiment also provides a specific process for adjusting the volume of the terminal, such as Figure 2 The specific steps are as follows:

[0079] 201. Detect whether the ambient sound type of the terminal has changed according to the adjacent sound parameters collected by the terminal. If yes, continue to execute step 201, if not, execute step 202.

[0080] According to the adjacent sound parameters collected by the terminal in the current collection cycle, detect whether the ambient sound type of the terminal has changed. Specifically, two ambient sound types can be obtained based on any two adjacent sound parameters in the current collection cycle. If there is a difference between the two ambient sound types, it can be considered that the ambient sound type of the terminal has changed. If the ambient sound type has changed, it is determined that the terminal is not in a stable state, and the adjacent sound parameters of the terminal in the next collection cycle are obtained to re-detect whether the ambient sound type of the terminal has changed.

[0081] 202. Detect whether the motion state of the terminal has changed according to the previous displacement parameter and the next displacement parameter of the terminal. If yes, execute step 201; if no, execute step 203.

[0082] If the ambient sound type has not changed, then detect whether the motion state of the terminal has changed based on the previous displacement parameter and the next displacement parameter of the terminal in the current acquisition cycle. It can be understood that the change in motion state specifically refers to whether the terminal has changed from a mobile state to a stationary state, or whether the terminal has changed from a stationary state to a mobile state. If the terminal has remained in a stationary state or has remained in a mobile state during the current acquisition cycle, it can be considered that the motion state of the terminal has not changed. The terminal can obtain multiple displacement parameters in the current acquisition cycle. Among the multiple displacement parameters, if there is a change between any two adjacent displacement parameters (i.e., the previous displacement parameter and the next displacement parameter), it is determined that the motion state of the terminal has changed.

[0083] If the motion state of the terminal changes, it is determined that the terminal is not in a stable state and adjacent sound parameters of the terminal in the next collection cycle are obtained again to detect whether the ambient sound type of the terminal has changed.

[0084] 203. Determine that the terminal is in a stable state.

[0085] If the motion state of the terminal does not change, the terminal is determined to be in a stable state. It is understandable that determining that the terminal is in a stable state requires two conditions: the ambient sound type of the first terminal has not changed, and the motion state of the second terminal has not changed. The condition for the termination of the loop is that the terminal is within a target collection period, the ambient sound type of the environment in which the terminal is located and the motion state of the terminal have not changed, and the sound parameters of the target collection period are collected.

[0086] 204. Determine the ambient sound type of the environment in which the terminal is located and determine the spatial scene type of the environment in which the terminal is located.

[0087] When determining the type of ambient sound in the environment where the terminal is located, the sound parameters of the environment where the terminal is located can be collected by controlling the audio collection module of the terminal, and the sound parameters include ambient background sound or human voice, etc., which are not specifically limited here. Determine the type of ambient sound in the environment where the terminal is located according to the sound parameters. Specifically, when the terminal is in a stable state, multiple sound parameters can be collected, and relevant sound features can be extracted from the multiple sound parameters to determine the type of ambient sound in the environment where the terminal is located.

[0088] The sound parameters of the terminal environment collected by the audio acquisition module can also be used to determine the spatial scene type of the terminal environment. Specifically, the target sound pressure amplitude of the terminal environment can be determined according to the sound parameters, and then, among multiple preset spatial scene types, the preset spatial scene type corresponding to the preset sound pressure amplitude and the target sound pressure amplitude is determined as the spatial scene type of the terminal environment. Among them, each preset spatial scene type has at least one corresponding preset sound pressure amplitude. Specifically, a mapping relationship between the preset spatial scene type and the preset sound pressure amplitude can be established to form a mapping library. Among them, at least one corresponding preset sound pressure amplitude is set for each preset spatial scene type in the mapping library. When it is determined that the target sound pressure amplitude of the terminal environment is within a certain preset sound pressure amplitude range, the preset spatial scene type corresponding to the preset sound pressure amplitude is determined as the spatial scene type of the terminal environment.

[0089] It is understandable that if Figure 7 As shown, the size of the sound can be expressed by the size of the sound pressure in dB (A). GB3096-2008 stipulates that the sound pressure of the bedroom is 45dB, the living room is 55dB, the conference room is 60dB, the cinema is 65dB, the museum is 50dB, the square road is 70dB-80dB, etc. The size of the sound pressure is different, and the type of scene can be identified by the size of the sound pressure. The sound parameters collected by the audio acquisition module are processed by algorithms such as noise reduction and remote sound pickup. The human voice and background noise are separated, and the background noise is processed by the algorithm to output an amplitude signal with a corresponding sound pressure of 0dB-100dB. In the algorithm library setting, the built-in scene feature acoustic parameter file, the scene feature sound pressure threshold is 45dB for the bedroom, 55dB for the living room, 65dB for the conference room, 65dB for the cinema, 70dB-80dB for the square road, etc. The real-time collected environmental background sound is converted into a sound pressure amplitude value, and compared one by one with the built-in scene feature sound pressure parameter file in the library, which can determine the type of space scene.

[0090] Furthermore, in order to make the collected sound parameters more accurate, the audio acquisition module needs to collect multiple sound parameters of the environment in which the terminal is located within the current acquisition cycle, and determine the ambient sound type and spatial scene type of the environment in which the terminal is located based on the multiple sound parameters within the current acquisition cycle. It can be understood that the current acquisition cycle mainly refers to the acquisition cycle in which the terminal is in a stable state, that is, the ambient sound type of the terminal and the motion state of the terminal in the current acquisition cycle have not changed. The multiple sound parameters include all the sound parameters within the current acquisition cycle as much as possible.

[0091] 205. Determine a prompt mode of the terminal according to the ambient sound type and the spatial scene type.

[0092] Step 205 is similar to the above step 103 and will not be described in detail here.

[0093] 206. If the prompt mode is the gentle disturbance mode or the reminder mode, determine whether the prompt mode of the terminal is set to the do not disturb mode within the last preset time period. If yes, execute step 208; if no, execute step 207.

[0094] Before the terminal needs to perform the reminder operation, the terminal needs to determine whether the terminal's reminder mode has been set to the do not disturb mode within the previous preset duration of the current collection cycle. It is understandable that there are multiple collection cycles in each preset duration, and the preset duration can be 5 minutes or 6 minutes, which is not limited here, preferably 5 minutes. Specifically, it can be determined whether the terminal is in do not disturb mode within the previous 5 minutes.

[0095] 207. The control terminal performs a reminder operation according to the reminder mode.

[0096] Step 207 is similar to step 104 and will not be described in detail here.

[0097] 208. Change the terminal's prompt mode to Do Not Disturb mode.

[0098] If the prompt mode of the terminal is determined to be the Do Not Disturb mode, the operation of the Do Not Disturb mode is performed. If the prompt mode of the terminal is the Gentle Disturbance mode or the Reminder mode, and the terminal determines that the prompt mode of the terminal has been determined to be the Do Not Disturb mode within the last preset time before the current collection cycle, the terminal changes the prompt mode to the Do Not Disturb mode.

[0099] Specifically, Figure 5As shown, when the terminal is a mobile phone, it can be determined whether the ambient sound type (environment) of the mobile phone has changed according to the adjacent sound parameters of the current collection cycle collected by the microphone on the mobile phone; it can be determined whether the motion state of the mobile phone has changed according to the acceleration sensor on the mobile phone, and the motion state can be understood as the state or position of the mobile phone. In the current collection cycle, it is necessary to judge whether the environment of the mobile phone and the state of the mobile phone have changed. When the environment of the mobile phone and the state or position of the mobile phone have not changed, the prompt mode is determined according to the ambient sound type and spatial scene type obtained in the current collection cycle. If the microphone detects that the environment has changed during the sound collection process of the current collection cycle, the next cycle is detected; if the environment has not changed, the acceleration sensor is used to detect whether there is a change in the state or position of the mobile phone; if there is a change, the next collection cycle is performed again to detect whether the environment has changed. If there is no change, it can be determined that the terminal is in a stable state in the corresponding collection cycle. The prompt mode of the terminal is determined according to the ambient sound type and spatial scene type obtained in the stable state. Before the terminal needs to perform a reminder operation, if the prompt mode of the terminal is determined to be the Do Not Disturb mode, the Do Not Disturb mode operation is performed; if the prompt mode of the terminal is the Gentle Disturbance Mode or the Reminder Mode, it is necessary to determine whether the prompt mode of the terminal is determined to be the Do Not Disturb mode within the preset time before the current collection cycle; if so, the prompt mode of the terminal is modified to the Do Not Disturb mode; if not, it is executed according to the Gentle Disturbance Mode or the Reminder Mode.

[0100] The process of adjusting the terminal volume is described above using the reminder sound as an example. The process of adjusting the terminal volume is described below using the content sound as an example. Figure 3 As shown, the specific steps are as follows:

[0101] 301. Determine the ambient sound type of the environment in which the terminal is currently located and determine a target application used by the terminal to play audio.

[0102] When the terminal determines that the terminal needs to perform an audio playback operation (i.e., play content audio) based on the application on the terminal, the ambient sound type of the current environment can be determined based on the audio acquisition module on the terminal, which is similar to step 102 and will not be repeated here. At the same time, the terminal can determine the target application for playing audio based on the application on the terminal. The target application can be determined based on the program being executed. The target application can be a video playback application or a call application, which is not specifically limited here.

[0103] 302. Determine an audio mode for playing audio on the terminal according to the ambient sound type and the target application.

[0104] After the terminal determines the ambient sound type and target application of the current environment, it determines the audio mode of the terminal to play the audio according to the ambient sound type and the target application. The audio mode refers to the relevant characteristics of the audio, which can be a sound quality priority mode, a volume priority mode, or a strong sound quality and strong volume mode, etc., which are not limited here. At this time, the ambient sound type is mainly divided into a noisy environment or a quiet environment, and the relevant target application can determine the audio mode of the terminal to play the audio.

[0105] 303. Control the terminal to play audio according to the audio mode.

[0106] After the audio mode of the terminal playing the audio is determined, the terminal is controlled to play the audio according to the audio mode. Figure 6 As shown, taking a mobile phone as a terminal, in a detection cycle, if the target application is a video playback application at this time, when the ambient sound type of the mobile phone is detected as being in a quiet environment, it is determined that the audio mode is the sound quality priority mode, and the volume is automatically adjusted to a low level when playing audio to ensure the sound quality of the audio; when the ambient sound type of the mobile phone is detected as being in a noisy environment, it is determined that the audio mode is the volume priority mode, and the volume is automatically adjusted to a medium-high level when playing audio. At the same time, when it is detected that the user is still pressing the volume key +, it is allowed to sacrifice a certain amount of sound quality in the short term to increase the volume to the maximum. If the target application is a microphone (MIC) broadcast or call scenario at this time, it is determined that the audio mode is a strong sound quality and strong volume mode, and noise reduction is used for receiving audio.

[0107] In the implementation of this application, when the terminal needs to play content sound, the audio mode of the terminal is determined by determining the ambient sound type and the target application, and the volume or sound quality of the terminal's external sound can be automatically adjusted according to different audio modes.

[0108] Further, the following uses the mobile phone as the terminal and combines Figure 4 Explain the process of intelligently adjusting the sound of the mobile phone:

[0109] When the sound that the mobile phone needs to play outward is a prompt sound, the type of ambient sound in the environment where the mobile phone is located can be determined based on the sound picked up by the microphone on the mobile phone. The movement state of the mobile phone can also be determined based on the acceleration sensor or displacement sensor on the mobile phone. The ambient sound type and the movement state of the mobile phone are sent to the processor (Sensor Hub) for collection and processing, with environmental detection given priority.

At this time, the application is prioritized. If the target application is an application that plays videos or music, and the ambient sound type is a quiet environment, the audio mode is determined to be a low-volume mode with sound quality priority, and the sound quality is delicate; if the target application is an application that plays videos or music, and the ambient sound type is a noisy environment, the audio mode is determined to be a medium-high volume mode with volume priority, and the volume is louder; if the target application is a voice call application or a microphone call scenario, the audio mode is determined to be a high-quality, high-volume mode with noise reduction, and the background sound is filtered to make the call clear.
