Embodiment Construction

[0013] 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.

[0014] The present invention firstly provides a voltage regulation method, which is applied to the terminal, including such as figure 1 Steps shown:

[0015] Step 101: Detect the volume change trend when the terminal plays the sound;

[0016] 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.

[0017] 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 cha...

Abstract

The present invention provides a voltage adjustment method and a terminal. The method comprises a step of detecting the volume change trend in playing sound by the terminal, a step of adjusting the voltage outputted by a terminal power supply module according to the detected volume change trend such that a voltage change trend is consistent with the volume change trend. The terminal comprises a volume change trend detection module for detecting the volume change trend in playing the sound by the terminal, a voltage adjusting module for adjusting the voltage outputted by the terminal power supply module according to the detected volume change trend such that the voltage change trend is consistent with the volume change trend.

Description

technical field [0001] The invention relates to the field of computers, in particular to a voltage regulation method and a terminal. Background technique [0002] 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 du...
