技术领域technical field
本发明涉及计算机领域，尤其涉及一种电压调节方法及终端。The invention relates to the field of computers, in particular to a voltage regulation method and a terminal.
背景技术Background technique
现有技术中，包括手机之类的终端基本都具备声音文件的播放功能，例如单纯音频文件播放、声音画面文件播放等。声音播放电路一般都包括运算放大器辅助信号的处理。终端目前在播放声音文件的过程中始终供应恒定的电压，比如±5V或±3V等。在终端播放声音的音量较小和音量较大时均向终端声音播放模块提供恒定的电压，在较小音量播放声音时，运算放大器的效率会降低，同时静态功耗和较大音量播放时一样大，这样导致声音播放电路效率低、播放过程中也会产生不必要的功耗。In the prior art, terminals including mobile phones basically have the function of playing sound files, such as playing pure audio files, playing sound and picture files, and so on. Sound playback circuits generally include operational amplifier auxiliary signal processing. Currently, the terminal always supplies a constant voltage during the playback of sound files, such as ±5V or ±3V. A constant voltage is provided to the terminal sound playback module when the volume of the sound played by the terminal is low or high. When the sound is played at a low volume, the efficiency of the operational amplifier will be reduced, and the static power consumption is the same as when the sound is played at a high volume. Large, which leads to low efficiency of the sound playback circuit and unnecessary power consumption during playback.
发明内容Contents of the invention
有鉴于此，本发明提供一种电压调节方法及终端，旨在解决小音量播放时消耗不必要的电能的问题。In view of this, the present invention provides a voltage regulation method and a terminal, aiming at solving the problem of unnecessary power consumption during low-volume playback.
基于上述目的本发明提供的电压调节方法，应用于终端，包括如下步骤：Based on the above purpose, the voltage regulation method provided by the present invention is applied to the terminal, including the following steps:
检测终端播放声音时的音量变化趋势；Detect the volume change trend when the terminal plays sound;
根据检测到的音量变化趋势调整所述终端电源模块输出的电压，使得电压变化趋势与音量变化趋势一致。The voltage output by the terminal power module is adjusted according to the detected volume change trend, so that the voltage change trend is consistent with the volume change trend.
同时，本发明还提供一种终端，包括：At the same time, the present invention also provides a terminal, including:
音量变化趋势检测模块：用于检测终端播放声音时的音量变化趋势；Volume change trend detection module: used to detect the volume change trend when the terminal plays sound;
电压调节模块：用于根据检测到的音量变化趋势调整所述终端电源模块输出的电压，使得电压变化趋势与音量变化趋势一致。A voltage regulation module: used to adjust the voltage output by the terminal power supply module according to the detected volume change trend, so that the voltage change trend is consistent with the volume change trend.
从上面所述可以看出，本发明所提供的一种电压调节方法及终端，能够根据终端播放声音时的音量调节终端电源模块所输出的电压，使得终端的电压在声音播放的过程中随着音量而变化，且电压供应的变化与音量的变化一致。在音量降低时，降低终端电源模块输出的电压，从而使得终端的声音播放电路中的运算放大器输入电压随之输出电压的降低而降低，在音量较小时，降低供给声音播放电路的运算放大器的输入电压，提高运算放大器的效率，减少音量较小时运算放大器所消耗的不必要的内耗，降低声音播放电路中运算放大器的静态功耗。It can be seen from the above that the voltage adjustment method and terminal provided by the present invention can adjust the voltage output by the terminal power supply module according to the volume when the terminal plays sound, so that the voltage of the terminal increases with the The volume changes, and the voltage supply changes in line with the volume change. When the volume is reduced, reduce the output voltage of the terminal power supply module, so that the input voltage of the operational amplifier in the audio playback circuit of the terminal decreases with the reduction of the output voltage, and when the volume is low, reduce the input of the operational amplifier supplied to the audio playback circuit Voltage, improve the efficiency of the operational amplifier, reduce unnecessary internal friction consumed by the operational amplifier when the volume is low, and reduce the static power consumption of the operational amplifier in the sound playback circuit.

图2为本发明实施例的终端结构示意图。FIG. 2 is a schematic diagram of a terminal structure according to an embodiment of the present invention.
具体实施方式detailed description
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
本发明首先提供一种电压调节方法，应用于终端，包括如图1所示的步骤：The present invention firstly provides a voltage regulation method, which is applied to the terminal, including the steps shown in Figure 1:
步骤101：检测终端播放声音时的音量变化趋势；Step 101: Detect the volume change trend when the terminal plays the sound;
步骤102：根据检测到的音量变化趋势调整所述终端电源模块输出的电压，使得电压变化趋势与音量变化趋势一致。Step 102: Adjust the voltage output by the terminal power module according to the detected volume change trend, so that the voltage change trend is consistent with the volume change trend.
从上面所述可以看出，本发明提供的电压调节方法，能够在终端播放声音是检测音量变化趋势，并根据音量变化趋势调整终端电源模块输出的电压，，使得电压变化与音量变化一致，即在音量升高时降低电压，或在音量降低时升高电压，从而在终端采用较小的音量播放声音时，声音播放电路的运算放大器的输入电压和输出电压压差较小，从而运算放大器的效率得到提高，声音播放电路的效率也得到了提高。It can be seen from the above that the voltage adjustment method provided by the present invention can detect the volume change trend when the terminal plays sound, and adjust the voltage output by the terminal power module according to the volume change trend, so that the voltage change is consistent with the volume change, that is When the volume is increased, the voltage is lowered, or when the volume is lowered, the voltage is increased, so that when the terminal uses a lower volume to play the sound, the difference between the input voltage and the output voltage of the operational amplifier of the sound playback circuit is small, so that the operational amplifier Efficiency is improved, as is the efficiency of sound playback circuits.
现有技术中，在声音播放的各个阶段都采用同样大小的电压供应，但终端播放声音的音量变小时，声音播放电路中的运算放大器输出电压变小，而这时若将较大的恒压供应给声音播放电路，那么运算放大器的输入电压和输出电压的差值变大，使得运算放大器的内耗增大，运算放大器的效率降低。本发明在音量变小后降低供给运算放大器的输入电压，使得运算放大器的内耗在音量较小时较小，运算放大器的效率增高，同时，由于在音量较小时供应的电压也较小，相对于现有技术中的恒压供应的方案，本发明能够减少声音播放电路所消耗的电能。In the prior art, the voltage supply of the same size is used in each stage of sound playback, but the volume of the sound played by the terminal becomes smaller, and the output voltage of the operational amplifier in the sound playback circuit becomes smaller. At this time, if a larger constant voltage If it is supplied to the sound playback circuit, the difference between the input voltage and the output voltage of the operational amplifier becomes larger, which increases the internal friction of the operational amplifier and reduces the efficiency of the operational amplifier. The present invention reduces the input voltage supplied to the operational amplifier after the volume is reduced, so that the internal friction of the operational amplifier is smaller when the volume is low, and the efficiency of the operational amplifier is increased. With the solution of constant voltage supply in the art, the present invention can reduce the power consumption of the sound playing circuit.
所述音量变化趋势，包括音量变大的情况以及音量变小的情况。在本发明具体实施例中，执行步骤101时，可通过检测声音信号或者检测音量控制指令等方式来检测终端播放声音时的音量变化趋势。而检测声音信号或检测音量控制指令是检测音量变化趋势较为直接的两种方式，在一些实施例中，还可以单独设置音量检测模块，接收即将播放的声音信号并对音强进行检测，从而获得音量变化趋势。The change trend of the volume includes the situation that the volume becomes larger and the situation that the volume becomes smaller. In a specific embodiment of the present invention, when step 101 is executed, the volume change trend when the terminal plays a sound can be detected by detecting a sound signal or detecting a volume control instruction. However, detecting sound signals or detecting volume control commands are two relatively direct ways to detect volume change trends. In some embodiments, a volume detection module can also be provided separately to receive the sound signal to be played and detect the sound intensity, thereby obtaining Volume change trend.
所述电源模块，为用于向终端的声音播放电路供电的模块，或用于向终端的声音播放电路中的运算放大器供电的模块。The power supply module is a module used to supply power to the sound playing circuit of the terminal, or a module used to supply power to an operational amplifier in the sound playing circuit of the terminal.
在执行步骤102时，可预先通过实验或其它方式确定不同音量所需要的最小电压，并建立对应的关系，当检测到音量变化趋势时，可根据预先建立的音量与电压的对应关系进行电压调节。When executing step 102, the minimum voltage required for different volumes can be determined in advance through experiments or other methods, and the corresponding relationship can be established. When the volume change trend is detected, the voltage can be adjusted according to the pre-established corresponding relationship between volume and voltage .
在其它实施例中，执行步骤102时，为了方便调控，可以通过实验或其它方式确定音量变化量与所需的最小电压的变化量之间的关系，当检测到音量趋势时，可根据预先建立的音量变化量与电压变化量的对应关系进行电压调节。In other embodiments, when step 102 is executed, for the convenience of regulation, the relationship between the volume change and the required minimum voltage change can be determined through experiments or other methods. When the volume trend is detected, the The corresponding relationship between volume change and voltage change is used for voltage adjustment.

在播放一个声音文件时，该文件的音量可能在不同播放进度处有所不同，例如，在一首歌曲文件中，歌唱者的声音有时较高，有时较低。因此在播放时需要对音量进行实时检测。由于声音波形的信号幅度是与声音响度有关的因素，当声音信号幅度变小时，音量变小；当声音信号幅度变大时，音量变大。因此，可通过检测声音波形的信号幅度判断音量的变化趋势。When playing a sound file, the volume of the file may be different at different playback progresses. For example, in a song file, the singer's voice is sometimes higher and sometimes lower. Therefore, the volume needs to be detected in real time during playback. Since the signal amplitude of the sound waveform is a factor related to the loudness of the sound, when the amplitude of the sound signal becomes smaller, the volume becomes smaller; when the amplitude of the sound signal becomes larger, the volume becomes louder. Therefore, the change trend of the volume can be judged by detecting the signal amplitude of the sound waveform.
