为便于理解，下面以Android系统为例，对Android系统中的音频系统架构进行简单说明。For ease of understanding, the following takes the Android system as an example to briefly describe the audio system architecture in the Android system.

如图1a所示，本实施例提供的音频系统架构主要包括用户空间、内核空间和硬件系统。用户空间包括应用(Application)层、应用框架(Framework)层和硬件抽象层(Hardware Abstraction Layer，HAL)，内核空间包括驱动(Driver)层，硬件系统包括扬声器、音频编解码器等。应用层是音频体系的最上层，可通过编写一个应用程序来执行对应的逻辑操作，例如预先设置设定遮挡环境包括扬声器被遮挡的环境，设定遮挡环境下移动终端与遮挡物的距离所属的设定范围，下发音量调整指令等。应用框架层包括音频控制接口和标准化插件模块负责提供获取音频属性信息、音频播放状态的接口，以及扬声器音量大小控制接口等。应用框架层提供了AudioTrack和AudioRecorder两个类，以及AudioManager、AudioService及AudioSystem类。在应用框架层和硬件抽象层之间还包括一个系统运行库(Libraries)层。我们知道，framework层的很多类，实际上只是应用程序使用Android库文件的“中介”而已。因为上层应用采用java语言编写，它们需要最直接的java接口的支持，这就是framework层存在的意义之一。而作为“中介”，它们并不会真正去实现具体的功能，或者只实现其中的一部分功能，而把主要重心放在库中来完成。比如上面的AudioTrack、AudioRecorder、MediaPlayer和MediaRecorder等等在库中都能找到相对应的类。这一部分代码集中放置在工程的frameworks/av/media/libmedia中，多数是C++语言编写的。音频方面的硬件抽象层主要分为两部分，即AudioFlinger和AudioPolicyService，实际上后者并不是一个真实的设备，只是采用虚拟设备的方式来让厂商可以方便地定制出自己的策略。根据产品的不同，音频设备存在很大差异，在Android的音频架构中，这些问题都是由HAL层的audio.primary等来解决的，而不需要大规模地修改上层实现。硬件抽象层是应用框架层到驱动层的过渡，以实现底层硬件的兼容。驱动层按照音频编解码器的特性对其进行控制，确保音频编解码器可以正常工作，将音频编解码器获取到的音频数据提供给系统层。硬件系统包括扬声器和音频编解码器，扬声器用于播放音频数据控制音量大小，音频编解码器用于解析音频数据的格式，如MP3、WMA，负责音频可以正常播放，不是噪音等。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 an application layer, an application framework (Framework) layer, and a hardware abstraction layer (HAL), the kernel space includes a driver layer, and the hardware system includes speakers, audio codecs, and the like. The application layer is the top layer of the audio system. You can write an application to perform corresponding logical operations. For example, pre-set the occlusion environment including the environment where the speaker is occluded, and set the distance between the mobile terminal and the occluder in the occlusion environment. Setting the range, issuing volume adjustment commands, etc. The application framework layer includes an audio control interface and a standardized plug-in module responsible for providing an interface for acquiring audio attribute information, audio playback status, and 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. It is responsible for the normal playback of audio, not noise, etc.

图1b为本发明实施例提供的一种智能手机的音频处理硬件系统结构示意图。音频处理电路一般处于主控电路板中，由于不同手机的设计不同，音频处理电路的具体位置也可能不同。智能手机的音频处理电路主要包括音频信号处理电路、基带信号处理电路、音频功率放大器、耳机信号放大器、听筒、扬声器、麦克风及耳机接口等。其中，音频信号处理电路是整个音频处理电路的核心。音频处理电路主要由接收音频电路、送话电路、耳机通话电路等组成，包括模拟音频的模拟/数字(A/D)转换、数字/模拟(A/D)转换、数字语音信号处理及模拟音频放大电路等。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.

在通话时，首先通话本地端麦克风把声音的机械声波信号转化为模拟音频信号，通过模拟音频放大电路进行放大，经内部的多模转换器进行A/D转换，得到数字音频信号；其次把此数字音频信号送到基带处理器，进行语音编码、信道编码等处理；再次进行加密、交织等一系列处理；最后送到基带处理器中的数字窄带制调模块进行调制，产生发射基带信号送入射频电路调制成发射中频，发送给通话对方。在接听电话时，首先从射频电路解调出接收基带信息，送到基带处理器内部进行数字窄带解调，分离出控制信号和语音信号；其次把语音信号进行解密、去交织、重组等一系列处理，然后进行信道解码、语音解码；最后得到纯正数字语音信号，送入语音信号处理器中的多模转换器进行D/A转换；还原成模拟音频信号后，经过音频功率放大后推动听筒发声。若选择免提受话，基带处理器则关闭听筒受话放大器，启动免提受话放大管(振铃放大管)工作，把音频信号功率放大后推动扬声器发声。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.

在录音时，与上述过程类似，首先由麦克风把声音的机械声波信号转化为模拟音频信号，通过模拟音频放大电路进行放大，经过A/D转换后得到数字音频信号，按照预设的音频格式进行编码及存储。在播放录音或其他音频文件时，将音频文件进行解码得到数字音频信号，经过D/A换后还原成模拟音频信号，把音频信号功率放大后推动扬声器发声。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.

本发明实施例中可预先在终端中存储预设音频文件，对该预设音频文件进行播放。预存音频文件以及预设音量等级可由设计人员根据实际情况进行选取，不同的声音播放器件对应的预设音频文件和/或预设音量等级可以不同，本发明实施例不做限定。麦克风采集的音频信号可以是上述的由机械声波信号转换而来的模拟音频信号，也可以是经过放大后的模拟音频信号，可根据两者的不同分别设置相应的下文中的预设条件，本发明实施例不作限定。为了方便终端与用户之间的交互，终端一般会向用户提供音量调节功能，用户可采用调节音量调节按钮或音量调节进度条等方式对终端播放声音的音量等级进行调整，而终端根据用户调整后的音量等级对需要播放的音频信号进行相应的放大处理，如功率放大，以满足用户的收听需求。不同的终端中对音量等级的划分策略可能不同，即具体的音量等级的总数量以及每个音量等级对应的音量大小都可能不同，本发明实施例不作限定。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.

图2给出了本发明实施例提供的一种移动终端的音量控制方法的流程图，本实施例的方法可以由移动终端的音量控制装置来执行，该装置可通过硬件和/或软件的方式实现，所述装置可作为移动终端一部分设置在所述移动终端的内部。2 shows a flowchart of a method for volume control of a mobile terminal provided by an embodiment of the present invention. The method of this embodiment may be executed by a volume control device of a mobile terminal, and the device 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.

如图2所示，本实施例提供的移动终端的音量控制方法包括以下步骤：As shown in FIG. 2 , the volume control method of the mobile terminal provided by this embodiment includes the following steps:

步骤101、确定移动终端处于设定遮挡环境中。Step 101: Determine that the mobile terminal is in a set occlusion environment.

本发明实施例提供的移动终端包括但不限定于智能手机、笔记本或者平板电脑等设备。The mobile terminals provided by the embodiments of the present invention include but are not limited to devices such as smart phones, notebooks, or tablet computers.

在移动终端的使用过程，可能存在移动终端被其他物体遮挡的情况，例如手机移动终端放入了口袋或者被置于杂物中等。该步骤用于确定移动终端处于设定遮挡环境中。所述设定遮挡环境为预先设定的满足扬声器被遮挡条件的遮挡环境，如上述的放入了口袋或者被置于杂物中。During the use of the mobile terminal, there may be situations in which the mobile terminal is blocked by other objects, for example, the mobile phone mobile terminal is put into a pocket or placed in sundries. This step is used to determine that the mobile terminal is in a set occlusion environment. The set occlusion environment is a preset occlusion environment that satisfies the condition of the speaker being blocked, such as being put into a pocket or placed in sundries as mentioned above.

步骤102、获取遮挡物的遮挡程度信息，所述遮挡物为所述设定遮挡环境中遮挡所述移动终端的物体。Step 102: Obtain information on the degree of occlusion of an occluder, where the occluder is an object that occludes the mobile terminal in the set occlusion environment.

当移动终端所处的遮挡环境不同时，遮挡物对移动终端的遮挡程度不同。所述遮挡环境的决定因素包括遮挡物与移动终端的距离，遮挡物的材质和厚度等，也即遮挡程度和遮挡物与移动终端的距离，遮挡物的材质和厚度相关联。When the blocking environment where the mobile terminal is located is different, the blocking degree of the blocking object to the mobile terminal is different. The determining factors of the blocking environment include the distance between the blocking object and the mobile terminal, the material and thickness of the blocking object, etc., that is, the blocking degree is related to the distance between the blocking object and the mobile terminal, and the material and thickness of the blocking object.

步骤103、根据所述遮挡程度信息调整音频播放音量。Step 103: Adjust the audio playback volume according to the occlusion degree information.

可根据遮挡物的遮挡程度信息来调整音频播放音量，该步骤可以包括：获取遮挡程度与音频播放音量的预设对应关系表，根据所述预设对应关系表确定与所述遮挡程度信息对应的音量调整值；将当前音频播放音量增加所述音量调整值，作为调整后的音频播放音量。在遮挡程度较大时则可根据预设对应关系表确定一个较大的音量调整值，在遮挡程度较小时则可根据预设对应关系表确定一个较小的音量调整值。The audio playback volume may be adjusted according to the occlusion degree information of the occluder, and this step may include: obtaining a preset correspondence table between the occlusion degree and the audio playback volume, and determining the corresponding occlusion degree information according to the preset correspondence table. Volume adjustment value; increase the current audio playback volume by the volume adjustment value as the adjusted audio playback volume. When the degree of occlusion is large, a larger volume adjustment value can be determined according to the preset correspondence table, and when the degree of occlusion is small, a smaller volume adjustment value can be determined according to the preset correspondence table.

其中，所述获取遮挡程度与音频播放音量的预设对应关系表，根据所述预设对应关系表确定与所述遮挡程度信息对应的音量调整值可以包括：确定移动终端的当前默认播放音量；获取遮挡程度与音频播放音量的预设对应关系表，根据所述当前默认播放音量和所述预设对应关系表确定与所述遮挡程度信息对应的音量调整值。在当前默认播放音量较小时，可确定一个相对较大的音量调整值，在当前默认播放音量较大时，则可确定一个相对较小的音量调整值。示例性的，遮挡程度A<遮挡程度B<遮挡程度C，最大播放音量为10，当前默认播放音量为2，则在遮挡程度为C时，可根据预设对应关系表确定音量调整值为4，即调整后的播放音量为6；而若当前播放音量为4，则在遮挡程度为C时，可根据预设对应关系表确定音量调整值为3，即调整后的播放音量为7；而若当前播放音量为2，则在遮挡程度为B时，可根据预设对应关系表确定音量调整值为3，即调整后的播放音量为5；而若当前播放音量为4，则在遮挡程度为B时，可根据预设对应关系表确定音量调整值为2，即调整后的播放音量为6。Wherein, acquiring the preset correspondence table between the occlusion degree and the audio playback volume, and determining the volume adjustment value corresponding to the occlusion degree information according to the preset correspondence table may include: determining the current default playback volume of the mobile terminal; Acquire a preset correspondence table between the occlusion degree and audio playback volume, and determine a volume adjustment value corresponding to the occlusion degree information according to the current default playback volume and the preset correspondence table. When the current default playback volume is low, a relatively large volume adjustment value may be determined, and when the current default playback volume is high, a relatively small volume adjustment value may be determined. Exemplarily, the occlusion degree A<the occlusion degree B<the occlusion degree C, the maximum playback volume is 10, and the current default playback volume is 2, then when the occlusion degree is C, the volume adjustment value can be determined to be 4 according to the preset correspondence table. , that is, the adjusted playback volume is 6; and if the current playback volume is 4, when the degree of occlusion is C, the volume adjustment value can be determined to be 3 according to the preset correspondence table, that is, the adjusted playback volume is 7; and If the current playback volume is 2, when the occlusion level is B, the volume adjustment value can be determined to be 3 according to the preset correspondence table, that is, the adjusted playback volume is 5; and if the current playback volume is 4, then the occlusion level When it is B, the volume adjustment value can be determined to be 2 according to the preset correspondence table, that is, the adjusted playback volume is 6.

本实施例提供的移动终端的音量控制方法，通过确定移动终端处于设定遮挡环境中，获取遮挡物的遮挡程度信息，所述遮挡物为所述设定遮挡环境中遮挡所述移动终端的物体，根据所述遮挡程度信息调整音频播放音量，避免移动终端处于遮挡环境中时音频播放音量过小而导致用户错过电话或者信息等问题，可以在移动终端处于被遮挡的情况下根据遮挡程度合理的控制移动终端的播放音量。In the volume control method for a mobile terminal provided in this embodiment, information on the occlusion degree of an occluder is obtained by determining that the mobile terminal is in a set occlusion environment, where the occluder is an object that occludes the mobile terminal in the set occlusion environment , adjust the audio playback volume according to the occlusion degree information, so as to avoid the problem that the audio playback volume is too low when the mobile terminal is in the occlusion environment and cause the user to miss calls or information, etc. Control the playback volume of the mobile terminal.

在上述实施例的基础上，可以是在检测到音频播放事件被触发时，确定移动终端处于设定遮挡环境中，也可以是定时检测移动终端所处的环境，并确定移动终端处于设定遮挡环境中。On the basis of the above-mentioned embodiment, it may be determined that the mobile terminal is in the set occlusion environment when it is detected that the audio playback event is triggered, or the environment in which the mobile terminal is located may be detected periodically, and it may be determined that the mobile terminal is in the set occlusion environment Environment.

图3给出了本发明实施例提供的另一种移动终端的音量控制法的流程图。如图3所示，本实施例提供的方法包括以下步骤：FIG. 3 is a flowchart of another method for controlling volume of a mobile terminal provided by an embodiment of the present invention. As shown in Figure 3, the method provided by this embodiment includes the following steps:

步骤201、通过移动终端的接近传感器获取所述移动终端与遮挡物的距离。Step 201: Obtain the distance between the mobile terminal and the obstruction through a proximity sensor of the mobile terminal.

其中，所述接近传感器与移动终端的扬声器的距离小于第一设定距离，这样设置的原因是：可以使移动终端将根据所述接近传感器获取的遮挡检测结果确定为所述扬声器的遮挡检测结果。所述第一设定距离可以为0cm-2cm，不包括0cm。一般移动终端的扬声器设置在移动终端的底部，则所述接近传感器可设置在移动终端底部靠近扬声器0cm-2cm的位置。The distance between the proximity sensor and the speaker of the mobile terminal is smaller than the first set distance, and the reason for this setting is that the mobile terminal can determine the occlusion detection result obtained according to the proximity sensor as the occlusion detection result of the speaker . The first set distance may be 0 cm-2 cm, excluding 0 cm. Generally, the speaker of the mobile terminal is arranged at the bottom of the mobile terminal, and the proximity sensor may be arranged at a position of 0cm-2cm at the bottom of the mobile terminal close to the speaker.

步骤202、通过移动终端的加速度传感器获取所述移动终端的运动状态。Step 202: Acquire the motion state of the mobile terminal through an acceleration sensor of the mobile terminal.

所述运动状态可以包括静止状态和运动状态。The motion state may include a rest state and a motion state.

步骤203、判断所述距离是否在第一设定范围内且所述运动状态是否为静止状态，若是，则执行步骤204，否则跳转执行步骤201或者步骤202。其中，所述第一设定范围为预先设定的一个距离范围，例如可以为0-0.5m。示例性的，移动终端与遮挡物贴合时，它们之间的距离为0m，在移动终端被放置于密封空间如抽屉里时，移动终端底部的接近传感器或者扬声器与抽屉的距离为5cm。Step 203 , judging whether the distance is within the first set range and whether the motion state is a static state, if so, go to step 204 , otherwise skip to step 201 orstep 202 . Wherein, the first setting range is a preset distance range, for example, may be 0-0.5m. Exemplarily, when the mobile terminal is attached to the shield, the distance between them is 0m, and when the mobile terminal is placed in a sealed space such as a drawer, the distance between the proximity sensor or speaker at the bottom of the mobile terminal and the drawer is 5cm.

步骤204、确定所述移动终端处于设定遮挡环境中。Step 204: Determine that the mobile terminal is in a set occlusion environment.

若用户正在使用移动终端，那么加速度传感器可以检测到移动终端处于运动状态，在移动终端处于运动状态下，即使接近传感器检测到移动终端与遮挡物的距离在第一设定范围内，也不确定为移动终端处于设定遮挡环境中。这样设置的原因是：避免音量的误调节，例如在用户接听电话的场景下，接近传感器靠近用户脸部与所述脸部这个遮挡物的距离在第一设定范围内，但移动终端其实并非处于设定遮挡环境中。而在移动终端被置于杂物中或者其他设定遮挡环境中时，移动终端是静止的。因此，通过加速度传感器获取移动终端的运动状态，在所述距离在第一设定范围内且处于运动状态时，才确定移动终端处于设定遮挡环境中。If the user is using the mobile terminal, the acceleration sensor can detect that the mobile terminal is in motion. When the mobile terminal is in motion, even if the proximity sensor detects that the distance between the mobile terminal and the obstruction is within the first set range, it is still uncertain. Set the occlusion environment for the mobile terminal. The reason for this setting is to avoid misadjustment of the volume. For example, in the scenario where the user answers the phone, the distance between the proximity sensor close to the user's face and the occluder on the face is within the first set range, but the mobile terminal is not actually in a set occlusion environment. However, when the mobile terminal is placed in the sundries or other set blocking environment, the mobile terminal is stationary. Therefore, the motion state of the mobile terminal is acquired through the acceleration sensor, and only when the distance is within the first set range and in the motion state, it is determined that the mobile terminal is in the set occlusion environment.

在利用与接近传感器结合加速度传感器确定移动终端与遮挡物的距离在第一设定范围内且移动终端的运动状态为静止状态时，可确定移动终端的接近传感器处于设定遮挡环境中，由于接近传感器在扬声器的附近，他们的距离小于第一设定距离，那么在接近传感器处于设定遮挡环境中时可确定扬声器也处于设定遮挡环境中。When it is determined by combining the acceleration sensor with the proximity sensor that the distance between the mobile terminal and the obstruction is within the first set range and the motion state of the mobile terminal is in a stationary state, it can be determined that the proximity sensor of the mobile terminal is in the set blocking environment. The sensors are in the vicinity of the speaker, and their distance is smaller than the first set distance, then when the proximity sensor is in the set occlusion environment, it can be determined that the speaker is also in the set occlusion environment.

步骤205、获取遮挡物的遮挡程度信息，所述遮挡物为所述设定遮挡环境中遮挡所述移动终端的物体。Step 205: Obtain information on the degree of occlusion of an occluder, where the occluder is an object that occludes the mobile terminal in the set occlusion environment.

步骤206、根据所述遮挡程度信息调整音频播放音量。Step 206: Adjust the audio playback volume according to the occlusion degree information.

其中，所述步骤201和步骤202的执行顺序可以调换。Wherein, the execution order of thestep 201 and thestep 202 can be exchanged.

本实施例提供的方法，通过移动终端的接近传感器获取移动终端与遮挡物的距离，通过移动终端的加速度传感器获取移动终端的运动状态，在检测到所述距离在第一设定范围内且所述运动状态为静止状态时，确定所述移动终端处于设定遮挡环境中，并根据遮挡物的遮挡程序信息调整音频播放音量，可以在移动终端处于被遮挡的情况下根据遮挡程度合理的控制移动终端的播放音量，并可以准确的确定移动终端处于设定遮挡环境中。In the method provided in this embodiment, the distance between the mobile terminal and the obstruction is obtained through the proximity sensor of the mobile terminal, and the motion state of the mobile terminal is obtained through the acceleration sensor of the mobile terminal. When the motion state is a static state, it is determined that the mobile terminal is in a set occlusion environment, and the audio playback volume is adjusted according to the occlusion program information of the occluder, so that the mobile terminal can be controlled reasonably according to the occlusion degree when the mobile terminal is occluded. The playback volume of the terminal can be accurately determined, and it can be accurately determined that the mobile terminal is in a set blocking environment.

图4给出了本发明实施例提供的另一种移动终端的音量控制法的流程图。如图4所示，本实施例提供的方法包括以下步骤：FIG. 4 is a flowchart of another method for controlling volume of a mobile terminal provided by an embodiment of the present invention. As shown in Figure 4, the method provided by this embodiment includes the following steps:

步骤301、通过移动终端的接近传感器获取所述移动终端的遮挡物的距离。Step 301: Acquire the distance of the obstruction of the mobile terminal through the proximity sensor of the mobile terminal.

步骤302、通过移动终端的环境光传感器获取所述移动终端的环境光亮度。Step 302: Acquire the ambient light brightness of the mobile terminal through the ambient light sensor of the mobile terminal.

其中，所述环境光传感器与移动终端的扬声器的距离小于第二设定距离，这样设置的原因是：可以使移动终端将根据所述环境光传感器获取的遮挡检测结果确定为所述扬声器的遮挡检测结果。所述第二设定距离可以为0cm-2cm，不包括0cm。一般移动终端的扬声器设置在移动终端的底部，则所述环境光感器可设置在移动终端底部靠近扬声器0cm-2cm的位置。The distance between the ambient light sensor and the speaker of the mobile terminal is smaller than the second set distance, and the reason for this setting is that the mobile terminal can determine the occlusion detection result obtained according to the ambient light sensor as the occlusion of the speaker. Test results. The second set distance may be 0cm-2cm, excluding 0cm. Generally, the speaker of the mobile terminal is arranged at the bottom of the mobile terminal, and the ambient light sensor may be arranged at a position of 0cm-2cm at the bottom of the mobile terminal close to the speaker.

其中，所述获取移动终端的环境光亮度可以为获取设定时间段内的环境光亮度的平均值。这样设置的原因是：根据一段时间内的环境光亮度而非瞬时或者短时间内的环境光亮度来确定移动终端是否处于设定遮挡环境中，可以避免由于用户不小心遮挡造成环境光亮度满足小于设定光亮度而导致误判为移动终端处于设定遮挡环境中。Wherein, the acquiring the ambient light brightness of the mobile terminal may be acquiring the average value of the ambient light brightness within a set time period. The reason for this setting is: to determine whether the mobile terminal is in the set blocking environment according to the ambient light brightness within a period of time rather than the instantaneous or short-term ambient light brightness, which can avoid the ambient light brightness satisfying less than Setting the brightness results in a misjudgment that the mobile terminal is in a set blocking environment.

步骤303、判断所述距离是否在第二设定范围内且所述环境光亮度是否小于设定光亮度，若是，则执行步骤304，否则跳转执行步骤301或者步骤302。其中，所述第二设定范围为预先设定的一个距离范围，例如可以为0-0.5m。Step 303 , determine whether the distance is within the second set range and whether the ambient light brightness is less than the set brightness, if so, go toStep 304 , otherwise skip to Step 301 orStep 302 . Wherein, the second setting range is a preset distance range, for example, may be 0-0.5m.

步骤304、确定所述移动终端处于设定遮挡环境中。Step 304: Determine that the mobile terminal is in a set occlusion environment.

在所述距离在第二设定范围内且所述环境光亮度小于设定光亮度时，确定所述移动终端处于设定遮挡环境中。一般，在移动终端处于被遮挡情况下，环境光亮度是比较暗的，若设定时间段内的环境光亮度的平均值小于设定光亮度，且距离在第二设定范围内，则确定移动终端处于设定遮挡环境中。When the distance is within the second set range and the ambient light brightness is less than the set light brightness, it is determined that the mobile terminal is in a set shading environment. Generally, when the mobile terminal is blocked, the ambient light brightness is relatively dark. If the average value of the ambient light brightness in the set time period is less than the set brightness, and the distance is within the second set range, it is determined that The mobile terminal is in a set occlusion environment.

步骤305、获取遮挡物的遮挡程度信息，所述遮挡物为所述设定遮挡环境中遮挡所述移动终端的物体。Step 305: Obtain information on the degree of occlusion of an occluder, where the occluder is an object that occludes the mobile terminal in the set occlusion environment.

步骤306、根据所述遮挡程度信息调整音频播放音量。Step 306: Adjust the audio playback volume according to the occlusion degree information.

本实施例提供的方法，通过移动终端的接近传感器获取移动终端与遮挡物的距离，通过移动终端的环境光传感器获取移动终端的运动状态，在检测到所述距离在第二设定范围内且所述环境光亮度小于设定光亮度时，确定所述移动终端处于设定遮挡环境中，并根据遮挡物的遮挡程序信息调整音频播放音量，可以在移动终端处于被遮挡的情况下根据遮挡程度合理的控制移动终端的播放音量，并可以准确的确定移动终端处于设定遮挡环境中。In the method provided in this embodiment, the distance between the mobile terminal and the obstruction is obtained through the proximity sensor of the mobile terminal, and the motion state of the mobile terminal is obtained through the ambient light sensor of the mobile terminal. When the ambient light brightness is less than the set light brightness, it is determined that the mobile terminal is in a set blocking environment, and the audio playback volume is adjusted according to the blocking program information of the blocking object. The playback volume of the mobile terminal is reasonably controlled, and it can be accurately determined that the mobile terminal is in a set blocking environment.

For example, if the speaker is arranged at the bottom of the mobile terminal, the ultrasonic transmitter can be arranged at a position of 0-2 cm (excluding 0 cm) near the speaker at the bottom of the mobile terminal.

步骤403、根据超声波传感器接收器接收到反射回来的超声波的强度，以及发射超声波与接收到反射回来的超声波的时间差，确定遮挡物的遮挡程度信息。Step 403 , according to the intensity of the reflected ultrasonic wave received by the ultrasonic sensor receiver, and the time difference between the transmitted ultrasonic wave and the received reflected ultrasonic wave, determine the occlusion degree information of the occluder.

其中，所述反射回来的超声波的强度越大，说明遮挡物的遮挡程度越小；所述时间差越长，那么表明遮挡物越不易穿透，比如遮挡物的厚度较大，那么说明遮挡程度越大。Wherein, the greater the intensity of the reflected ultrasonic waves, the smaller the degree of occlusion; the longer the time difference, the more difficult it is for the occlusion to penetrate, for example, the greater the thickness of the occlusion, the greater the degree of occlusion big.

在某种实施方式中，可以利用移动终端的扬声器作为超声波发射器向遮挡物发射超声波，以及利用移动终端的麦克风作为超声波接收器接收反射回来的超声波。In a certain implementation manner, the speaker of the mobile terminal may be used as an ultrasonic transmitter to transmit ultrasonic waves to the obstruction, and the microphone of the mobile terminal may be used as an ultrasonic receiver to receive the reflected ultrasonic waves.

图6给出了本发明实施例提供的另一种移动终端的音量控制方法的流程图。如图6所示，本实施例提供的移动终端的音量控制方法包括以下步骤：FIG. 6 is a flowchart of another method for volume control of a mobile terminal provided by an embodiment of the present invention.

步骤503、控制所述移动终端的振动马达产生设定频率的振动。Step 503: Control the vibration motor of the mobile terminal to generate vibration of a set frequency.

在遮挡物与移动终端的距离小于第二设定距离时，可通过控制移动终端的马达产生振动来检测遮挡物的材质。其中，所述第二设定距离的取值范围可以为0cm-1cm。When the distance between the blocking object and the mobile terminal is less than the second set distance, the material of the blocking object can be detected by controlling the motor of the mobile terminal to generate vibration. Wherein, the value range of the second set distance may be 0cm-1cm.

步骤504、通过移动终端的加速度传感器获取所述振动产生的加速度采样值，和/或，通过移动终端的声音传感器获取所述振动产生的声音采样值。Step 504: Acquire the acceleration sample value generated by the vibration through the acceleration sensor of the mobile terminal, and/or obtain the sound sample value generated by the vibration through the sound sensor of the mobile terminal.

其中，所述通过移动终端的加速度传感器获取所述振动产生的加速度采样值可以包括：设定加速度值采样时间，通过移动终端的加速度传感器获取所述加速度值采样时间内所述振动产生的加速度采样值。所述加速度值采样时间可设置为5秒钟。Wherein, the acquiring the acceleration sampling value generated by the vibration through the acceleration sensor of the mobile terminal may include: setting an acceleration value sampling time, and acquiring the acceleration sampling value generated by the vibration during the acceleration value sampling time through the acceleration sensor of the mobile terminal value. The acceleration value sampling time can be set to 5 seconds.

所述通过移动终端的声音传感器获取所述振动产生的声音采样值可以包括：通过移动终端的声音传感器采集移动终端振动时与遮挡物碰撞产生的声音。所述声音传感器可以由移动终端的麦克风替代。The acquiring the sound sample value generated by the vibration through the sound sensor of the mobile terminal may include: collecting, through the sound sensor of the mobile terminal, the sound generated by the collision of the mobile terminal with the obstruction when the mobile terminal vibrates. The sound sensor may be replaced by a microphone of the mobile terminal.

步骤505、根据所述加速度采样值和/或所述声音采样值，确定所述遮挡物的材质类型。Step 505: Determine the material type of the occluder according to the acceleration sample value and/or the sound sample value.

其中，所述根据所述加速度采样值，确定所述遮挡物的材质类型可以包括：对所述加速度采样值进行频谱分析，根据分析结果确定所述遮挡物的材质类型。所述对所述加速度采样值进行频谱分析可以包括：对所述加速度采样值进行快速傅氏变换，将时域采样值转化为频域采样值，进行频谱特性分析。根据分析结果可确定遮挡物所属介质材料的类型。The determining the material type of the occluder according to the acceleration sample value may include: performing spectrum analysis on the acceleration sample value, and determining the material type of the occluder according to the analysis result. The performing spectrum analysis on the acceleration sampled value may include: performing fast Fourier transform on the acceleration sampled value, converting the time-domain sampled value into a frequency-domain sampled value, and performing spectrum characteristic analysis. According to the analysis results, the type of medium material to which the shield belongs can be determined.

所述根据所述声音采样值，确定所述遮挡物的材质类型可以包括：对所述碰撞产生的声音进行声音频谱图分析，根据分析结果可确定遮挡物所属介质材料的类型。The determining of the material type of the blocking object according to the sound sample value may include: performing a sound spectrogram analysis on the sound generated by the collision, and determining the type of the medium material to which the blocking object belongs according to the analysis result.

另外，也可以先通过加速度传感器获取所述振动产生的加速度采样值，根据所述加速度采样值确定遮挡物所属介质材料的软硬程度，例如，通过对加速度采样值进行频谱分析，可确定遮挡物为木书桌、石头等硬材质或者衣物、包等软材质；然后再通过声音传感器获取所述振动产生的声音采样值，根据所述声音采样值对软硬程度相似的介质材料进行区分，例如，通过对声音频谱进行分析，可以确定遮挡物的材质具体为木书桌还是石头。In addition, the acceleration sampling value generated by the vibration can also be obtained first through the acceleration sensor, and the hardness of the medium material to which the obstruction belongs is determined according to the acceleration sampling value. For example, the obstruction can be determined by performing spectrum analysis on the acceleration sampling value. It is a hard material such as a wooden desk, stone, or a soft material such as clothes and bags; then the sound sampling value generated by the vibration is obtained through the sound sensor, and the medium materials with similar degrees of softness and hardness are distinguished according to the sound sampling value, for example, By analyzing the sound spectrum, it can be determined whether the material of the occluder is a wooden desk or a stone.

当遮挡物为衣物时产生的加速度频域分析图包络线与频率冲击响应比木质材质或者石头响应强烈。对于低频率阶段而言，可以发现，软介质材料上的频率值已经趋向于0，而硬介质材料的频率值却一直有非零值的存在。这样通过频率便可区分出衣物与木书桌、石头的区别；通过移动终端自带的声音传感器采集振动时的声音，并对该音频进行声音频谱图分析，可知，当遮挡物为石头材质时产生频率冲击响应比木质材质时的响应强烈，当声音振动频率大约为200Hz左右时，木质材质表面的音频振幅小于石头材质，因此便可以通过设置频率阈值来对木质材质以及石制材质进行区分。When the occluder is clothing, the envelope and frequency impact response of the acceleration frequency domain analysis graph are stronger than those of wood or stone. For the low frequency stage, it can be found that the frequency value of the soft dielectric material has tended to 0, while the frequency value of the hard dielectric material has always existed non-zero value. In this way, the difference between clothes, wooden desks and stones can be distinguished by frequency; the sound during vibration is collected by the sound sensor built in the mobile terminal, and the sound spectrum is analyzed for the audio. The frequency impact response is stronger than that of the wood material. When the vibration frequency of the sound is about 200Hz, the audio amplitude on the surface of the wood material is smaller than that of the stone material. Therefore, the wood material and the stone material can be distinguished by setting the frequency threshold.

步骤506、根据所述遮挡物的材质类型，确定所述遮挡物的遮挡程度信息。Step 506: Determine the occlusion degree information of the occluder according to the material type of the occluder.

示例性的，在所述遮挡物的材质为石头时可确定遮挡物的遮挡程度为a，在所述遮挡物的材质为木书桌时可确定遮挡物的遮挡程度为b，在所述遮挡物的材质为衣物时可确定遮挡物的遮挡程度为c，其中，所述遮挡程度a>遮挡程度b>遮挡程度c。Exemplarily, when the material of the occluder is stone, the occlusion degree of the occluder can be determined to be a; When the material of is clothing, the degree of occlusion of the occluder can be determined to be c, where the degree of occlusion a>the degree of occlusion b>the degree of occlusion c.

步骤507、根据所述遮挡程度信息调整音频播放音量。Step 507: Adjust the audio playback volume according to the occlusion degree information.

示例性的，根据遮挡程度a可确定音量调整值为a`，根据遮挡程度b可确定音量调整值为b`，根据遮挡程度c可确定音量调整值为c`，其中，音量调整值a`>音量调整值b`>音量调整值c`。Exemplarily, according to the degree of occlusion a, it can be determined that the volume adjustment value is a', according to the degree of occlusion b, it can be determined that the volume adjustment value is b', and according to the degree of occlusion c, the volume adjustment value can be determined to be c', wherein the volume adjustment value a' >Volume adjustment value b`>Volume adjustment value c`.
