Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all of the contents related to the present invention. Before discussing the exemplary embodiments in greater detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart depicts various operations (or steps) as a sequential process, many of the operations may be performed in parallel, concurrently, or concurrently. Additionally, the order of operations can be rearranged. The process may be terminated when its operation is complete, but may also have additional steps not included in the figures. The processes may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

For ease of understanding, the following takes the Android system as an example to briefly describe the audio system architecture in the Android system.

As shown in FIG. 1a, the audio system architecture provided by this embodiment mainly includes a user space, a kernel space, and a hardware system. The user space includes the application layer, the application framework (Framework) layer, and the hardware abstraction layer (HAL), the kernel space includes the driver layer, and the hardware system includes speakers, audio codecs, etc., and can also include earphone. The application layer is the top layer of the audio system. You can write an application program to perform corresponding logical operations, such as detecting whether an audio playback event is triggered, presetting the first set time and the second set time, and issuing audio playback instructions. Wait. The application framework layer includes an audio control interface and a standardized plug-in module responsible for providing an audio playback form control interface, as well as a speaker volume control interface. The application framework layer provides AudioTrack and AudioRecorder classes, as well as AudioManager, AudioService and AudioSystem classes. A system runtime library (Libraries) layer is also included between the application framework layer and the hardware abstraction layer. We know that many classes in the framework layer are actually just "intermediaries" for applications to use Android library files. Because upper-layer applications are written in java language, they need the support of the most direct java interface, which is one of the meanings of the existence of the framework layer. As "intermediaries", they do not really implement specific functions, or only implement a part of them, and focus on the library to complete. For example, the above AudioTrack, AudioRecorder, MediaPlayer and MediaRecorder can find corresponding classes in the library. This part of the code is placed in the frameworks/av/media/libmedia of the project, and most of them are written in C++ language. The hardware abstraction layer in audio is mainly divided into two parts, namely AudioFlinger and AudioPolicyService. In fact, the latter is not a real device, but a virtual device is used to allow manufacturers to easily customize their own policies. Depending on the product, there are great differences in audio devices. In the audio architecture of Android, these problems are solved by the audio.primary of the HAL layer, without the need to modify the upper layer implementation on a large scale. The hardware abstraction layer is the transition from the application framework layer to the driver layer to realize the compatibility of the underlying hardware. The driver layer controls the audio codec according to its characteristics, ensures that the audio codec can work normally, and provides the audio data obtained by the audio codec to the system layer. The hardware system includes a speaker and an audio codec. The speaker is used to play audio data to control the volume. The audio codec is used to parse the format of the audio data, such as MP3 and WMA, which is responsible for the normal playback of audio.

FIG. 1b is a schematic structural diagram of an audio processing hardware system of a smart phone according to an embodiment of the present invention. The audio processing circuit is generally located in the main control circuit board. Due to the different designs of different mobile phones, the specific location of the audio processing circuit may also be different. The audio processing circuit of a smartphone mainly includes an audio signal processing circuit, a baseband signal processing circuit, an audio power amplifier, a headphone signal amplifier, an earpiece, a speaker, a microphone and a headphone interface. Among them, the audio signal processing circuit is the core of the entire audio processing circuit. The audio processing circuit is mainly composed of receiving audio circuit, sending circuit, earphone calling circuit, etc., including analog/digital (A/D) conversion of analog audio, digital/analog (A/D) conversion, digital voice signal processing and analog audio Amplifier circuit, etc.

During a call, firstly, the local microphone of the call converts the mechanical sound wave signal of the sound into an analog audio signal, which is amplified by the analog audio amplifier circuit, and then A/D converted by the internal multi-mode converter to obtain a digital audio signal; The digital audio signal is sent to the baseband processor for voice coding, channel coding and other processing; again, a series of processes such as encryption and interleaving are carried out; finally, it is sent to the digital narrowband modulation module in the baseband processor for modulation to generate a transmitting baseband signal and send it to the The radio frequency circuit is modulated to transmit intermediate frequency and sent to the other party of the call. When answering a call, firstly demodulate the received baseband information from the radio frequency circuit and send it to the baseband processor for digital narrowband demodulation to separate the control signal and the voice signal; secondly, the voice signal is decrypted, deinterleaved, reorganized, etc. After processing, channel decoding and voice decoding are performed; finally, a pure digital voice signal is obtained, which is sent to the multi-mode converter in the voice signal processor for D/A conversion; after being restored to an analog audio signal, the audio power is amplified to push the earpiece to sound. . If the speakerphone is selected, the baseband processor will turn off the receiver receiver amplifier, start the speakerphone amplifier tube (ring amplifier tube), and amplify the power of the audio signal to push the speaker to sound.

When recording, similar to the above process, the mechanical sound wave signal of the sound is first converted into an analog audio signal by the microphone, amplified by the analog audio amplifier circuit, and the digital audio signal is obtained after A/D conversion, which is performed according to the preset audio format. encoding and storage. When playing recordings or other audio files, the audio files are decoded to obtain digital audio signals, which are restored to analog audio signals after D/A conversion, and the audio signal power is amplified to push the speaker to sound.

In this embodiment of the present invention, a preset audio file may be stored in the terminal in advance, and the preset audio file may be played. The pre-stored audio file and the preset volume level can be selected by the designer according to the actual situation. The preset audio file and/or the preset volume level corresponding to different sound playback devices may be different, which is not limited in the embodiment of the present invention. The audio signal collected by the microphone can be the above-mentioned analog audio signal converted from the mechanical sound wave signal, or it can be an amplified analog audio signal, and the corresponding preset conditions below can be set according to the difference between the two. The embodiments of the invention are not limited. In order to facilitate the interaction between the terminal and the user, the terminal generally provides the user with a volume adjustment function. The user can adjust the volume level of the sound played by the terminal by adjusting the volume adjustment button or the volume adjustment progress bar. The audio signal to be played is amplified accordingly, such as power amplification, to meet the listening needs of users. Different terminals may have different strategies for dividing volume levels, that is, the total number of specific volume levels and the volume corresponding to each volume level may be different, which are not limited in this embodiment of the present invention.

FIG. 2 shows a flowchart of a method for controlling audio playback volume provided by an embodiment of the present invention. The method in this embodiment may be performed by a device for controlling audio playback volume, which may be implemented by means of hardware and/or software. Implementing, the apparatus may be provided inside the mobile terminal as part of the mobile terminal.

As shown in FIG. 2 , the method for controlling the audio playback volume provided by this embodiment includes the following steps:

Step 101: When it is detected that the audio playback event is triggered, obtain the noise-related information of the external environment where the mobile terminal is located within the current first set time, and the noise-related information includes the noise intensity, noise source, noise type and the current state of the mobile terminal. at least one of the locations.

The mobile terminal described in this embodiment includes a device with an audio playback function, such as a mobile phone, a notebook, and a tablet computer.

Exemplarily, in application scenarios such as ringtones for incoming calls, song playback, video playback, or game sound playback, before playing the audio of these ringtones, songs, videos, or games, it may be detected that a corresponding audio playback event is triggered, for example, detecting When an incoming call signal is received, or when a user's touch instruction acting on the play button is detected, it is determined that an audio play event is detected to be triggered.

In a certain implementation manner, the noise intensity of the external environment where the mobile terminal is located can be collected through components such as a microphone of the mobile terminal, and when the microphone monitors noise, the duration of the noise is timed by a timer on the mobile terminal, To get the duration of the noise, and then determine the type of noise. In one embodiment, acquiring the type of noise within the first set time may include: if the duration of the noise is within the first time range, determining that the noise is a continuous type; if the duration of the noise is within the second time range, determining Noise is temporary. The first time range and the second time range may be determined according to the type or identifier of the application that triggers the audio playback. For example, if the current application that triggers the audio playback event is a phone, the first time The range may be about 10 seconds, and the second time range may be about 5 seconds. If the current application that triggers the audio playback event is video, the first time range may be about 1 minute, and the second time range Can be about 10 seconds.

In this embodiment, the noise source to which it belongs may be determined according to the frequency of the noise collected by the microphone. Wherein, the noise source includes human voice noise and non-human voice noise, such as human shouting, and the noise source also includes non-human voice noise, such as noise from equipment operation, noise from construction, or weather conditions Harsh noise, etc. Generally, the frequency range of human voice is 100 Hz-700 Hz, and the sharper the voice, the higher the frequency. Human voices at 400-700 can be determined to be human voice noise. Of course, human voice noise samples can be stored in advance, the audio data is compared with the human voice noise samples, and when the similarity is greater than the set similarity, it is determined that the audio data is human voice noise. The factors considered in the comparison can include frequency, amplitude and timbre.

In addition, a sound sensor may be additionally provided in the mobile terminal to collect the noise intensity and noise source. The positioning of the mobile terminal can be performed through GPS on the mobile terminal or a base station in a communication network to obtain the current location information of the mobile terminal, and the current location information can be represented by longitude and latitude.

Wherein, the start time of the first set time is the time when the audio playback event is detected to be triggered or the time when the audio starts to be played. The first set time may also be determined according to the application that triggers the audio playback event, and the first set time corresponding to different applications may also be different. For example, if the application that triggers the audio playback event is a phone, the first set time can be set to 10 seconds; if the application that triggers the audio playback event is a video, the first set time can be set to 1 minute. Correspondingly, the method may further include: determining a current application that triggers an audio playback event; and acquiring a first set time corresponding to the current application.

Based on the above technical solution, the method further includes: in the process of acquiring the noise-related information of the external environment where the mobile terminal is located within the current first set time, enabling an echo cancellation algorithm to eliminate the movement of the mobile terminal within the first set time. Audio data played by the speaker of the mobile terminal collected by the terminal microphone.

Step 102: Determine the volume adjustment value within a second set time according to the noise-related information within the current first set time, the start time of the second set time and the difference between the current first set time The end time is the same.

Wherein, the second set time corresponds to the first set time. As in the above example, when the application triggering the audio playback event is a phone, the second set time can be 10 seconds or 5 seconds, and when the application triggering the audio playback event is a game, the second set time can be 1 minutes or 30 seconds.

Exemplarily, when receiving the incoming call signal and the telephone ringing, obtain the noise-related information of the external environment where the mobile terminal is located during the first set time after the telephone ringing, for example, 10 seconds. For related information, it can be determined that the volume adjustment value within the second time after the 10 seconds, for example, within 5 seconds, is increased by 2 basic volumes.

The volume adjustment value may be a positive value, indicating that the volume adjustment value is increased on the basis of the original playback volume.

Step 103: Adjust the audio playback volume within the second set time according to the volume adjustment value.

Exemplarily, within 5 seconds after the 10 seconds, the playback volume within the 5 seconds is adjusted to increase the playback volume after 2 basic volumes to perform audio playback. Exemplarily, when the ringtone is ringing, if the ambient noise is relatively loud, the user may not perceive the sound of the ringtone. Adjusting the playback volume within the second set time allows the user to hear the ringtone as soon as possible in a noisy environment, preventing missed calls.

After the volume is adjusted, the next first set time may be re-determined, the next first set time may be regarded as the new current first set time, and steps 101 to 103 may be executed cyclically.

In the method provided in this embodiment, when an audio playback event is detected to be triggered, the noise-related information of the external environment where the mobile terminal is located within the current first set time is acquired, and the noise-related information within the current first set time is obtained according to the information, determine the volume adjustment value within the second set time, and adjust the audio playback volume within the second set time according to the volume adjustment value, which can be reasonably based on the noise-related information in the previous first set time. to control the playback volume of the audio within the second set time after the mobile terminal.

On the basis of the above embodiment, the volume of the mobile terminal includes the ringing volume, the earpiece volume and the multimedia data playback volume, and the second set time is determined according to the noise-related information in the current first set time The volume adjustment value within includes: determining the ringing volume adjustment value or the earpiece volume adjustment value or the multimedia data playback volume adjustment value within the second set time according to the noise-related information in the current first set time. The adjusting the audio playback volume within the second set time according to the volume adjustment value includes: adjusting the ringtone playback volume within the second set time according to the ringtone volume adjustment value; or, according to The earpiece volume adjustment value is used to adjust the earpiece playback volume within the second set time; or, according to the multimedia data volume adjustment value, the multimedia data playback volume within the second set time is adjusted.

FIG. 3 is a flowchart of another method for controlling audio playback volume provided by an embodiment of the present invention. As shown in Figure 3, the method provided by this embodiment includes the following steps:

Step 201: When it is detected that an audio playback event is triggered, acquire the noise intensity of the external environment where the mobile terminal is located within the current first set time.

Step 202: Obtain the average value of the noise intensity within the current first set time.

The noise intensity may not be stable within the first set time. It is inaccurate to determine whether to adjust the volume based on the noise intensity at a certain moment, such as when an audio event is detected. Noise may not affect the playback of audio following subsequent noise. In this embodiment, this step is used to obtain the average value of the noise intensity within the current first set time.

Step 203: Determine the volume adjustment value within the second set time period according to the average value of the noise intensity.

This step may include: when the average value of the noise intensity is greater than the set intensity value, determining the volume adjustment value within the second set time to the first set volume adjustment value. This step may further include: determining the corresponding noise level according to the average value of the noise intensity; acquiring a second preset correspondence table including the noise level and the volume adjustment value; looking up the noise level from the second preset correspondence table Corresponding volume adjustment value.

Step 204: Adjust the audio playback volume within the second set time according to the volume adjustment value.

In the method provided in this embodiment, when an audio playback event is detected to be triggered, the average value of the noise intensity of the external environment where the mobile terminal is located within the current first set time is obtained, and the second device is determined according to the average value of the noise intensity. The volume adjustment value within a fixed time period, according to the volume adjustment value, the audio playback volume in the second set time period is adjusted, and the mobile terminal can be reasonably controlled according to the average value of the noise intensity within the first set time period. 2. The playback volume of the audio within the set time.

FIG. 4 is a flowchart of another method for controlling audio playback volume provided by an embodiment of the present invention. As shown in Figure 4, the method provided by this embodiment includes the following steps:

Step 301: When it is detected that an audio playback event is triggered, acquire the noise intensity, noise source and current position of the mobile terminal of the external environment where the mobile terminal is located within the current first set time.

Step 302 , determine whether the noise source is human voice noise, if yes, go to step 303 , otherwise go to step 304 .

If the noise source is human voice noise, the volume adjustment value within the second set time is determined according to the current position of the mobile terminal.

Step 303 , determine whether the current position is the first set position, if so, go to step 305 , otherwise go to step 306 .

The first set location is a preset relatively quiet place, such as a conference room, a classroom, or a library. These places are generally quiet, but there may also be situations such as intense discussions or presentations. In these situations, the volume needs to be turned down. In the prior art, as long as loud noise is detected, the The playback volume will be increased, resulting in that the adjustment of the playback volume does not conform to the real scene, and the accuracy is not high. In this embodiment, when it is detected that the noise source is human voice noise, the current position of the mobile terminal is further judged, The volume adjustment value is determined according to the current position, and the adjustment of the playback volume is more accurate.

Step 304: Determine the volume adjustment value within the second set time according to the noise intensity.

If the noise source within the first set time is non-human voice noise, the volume adjustment value within the second set time is determined according to the noise intensity. The volume adjustment value is a positive value.

Step 305: Determine the volume adjustment value within the second set time as the first volume value.

If it is detected that the noise source is human voice noise and the current position is the first set position, the volume adjustment value is determined as the first volume value. The first volume value may be a negative value, that is, the playback volume is decreased by the first volume value.

Step 306: Determine the volume adjustment value within the second set time to a second volume value. Wherein, the second volume value is greater than the first volume value.

If it is detected that the noise source is human voice noise and the current position is not the first set position, the volume adjustment value is determined as the second volume. Wherein, the second volume value is a positive value. Exemplarily, when it is detected that the noise source is human voice noise and the current location is a certain KTV karaoke hall, the volume adjustment value may be determined as the second volume.

Step 307: Adjust the audio playback volume within the second set time according to the volume adjustment value.

In the method provided by this embodiment, when an audio playback event is detected to be triggered, the noise intensity of the external environment where the mobile terminal is located, the noise source and the current position of the mobile terminal are acquired within the current first set time. The noise source within the set time is non-human voice noise, then the volume adjustment value within the second set time is determined according to the noise intensity, and if the noise source within the first set time is human voice noise, then the volume adjustment value is determined according to the noise intensity. The current position of the mobile terminal determines the volume adjustment value within the second set time, and can reasonably control the second set after the mobile terminal according to the noise intensity, noise source and the current position of the mobile terminal in the previous first set time. The playback volume of the audio for a certain period of time.

Step 401: When it is detected that an audio playback event is triggered, the duration of the external environment noise where the mobile terminal is located within the first set time is acquired, and the noise type is determined according to the duration.

The noise types include persistent and transient. In one embodiment, acquiring the type of noise within the first set time may include: if the duration of the noise is within the first time range, determining that the noise is a continuous type; if the duration of the noise is within the second time range, determining Noise is temporary. The first time range and the second time range may be determined according to the type or identifier of the application that triggers the audio playback. For example, if the current application that triggers the audio playback event is a phone, the first time The range may be about 10 seconds, and the second time range may be about 5 seconds. If the current application that triggers the audio playback event is video, the first time range may be about 1 minute, and the second time range Can be about 10 seconds.

Step 402 , determine whether the noise type is a persistent type, if yes, go to Step 403 , otherwise go to Step 404 .

Step 403: Determine the duration of the second set time as the first duration and determine the volume adjustment value within the second set time.

When the noise type is continuous, it indicates that the current external environment may be affected by noise for a longer period of time, and the second set period of time may be determined as the longer first period of time, so that the longer period of the first The audio is played at the volume after the volume adjustment value has been increased for both periods of time.

Step 404 , determine whether the noise type is a transient type, if so, go to Step 405 , otherwise end the process.

The noise type includes an intermediate type in addition to the persistent type and the transient type, and the duration of the intermediate type in the third time range is greater than the second time range and smaller than the first time range. For example, if the first time range is about 10 seconds and the second time range is about 5 seconds, then the third time range may be 5 seconds to 10 seconds (excluding 5 seconds and 10 seconds).

If the noise type is an intermediate type, the duration of the second time may be determined as a third duration, and the volume adjustment value in the second duration may be determined, and the third duration may be greater than the second duration and less than the first duration.

Step 405: Determine the duration of the second time as the second duration, and determine the volume adjustment value within the second set time, where the second duration is smaller than the first duration.

When the noise type is short-lived, it indicates that the noise impact time of the current external environment may be relatively short, and then the duration of the second set time may be determined as a shorter second duration, so that in the shorter first The audio is played at the volume after the volume adjustment value has been increased within the second time. And acquire the noise-related information within the next current first set time as soon as possible.

Step 406: Adjust the audio playback volume within the second set time according to the volume adjustment value.

In the method provided by this embodiment, when it is detected that an audio playback event is triggered, the duration of the noise in the external environment where the mobile terminal is located within the first set time is acquired, and the type of noise is determined according to the duration, and when the noise is When the type is continuous type, the duration of the second set time is determined as the first duration and the volume adjustment value within the second set time is determined; when the noise type is transient type, the duration of the second time is determined as the second duration. duration and determine the volume adjustment value within the second set time, the second duration is smaller than the first duration, and according to the volume adjustment value, the audio playback volume in the second set time can be adjusted according to the first The noise type within the set time, and reasonably control the audio playback volume within the second set time after the mobile terminal.
