Audio output power control method, mobile terminal and storage medium

Abstract

The invention discloses an audio output power control method, a mobile terminal and a storage medium. The audio output power control method includes the following steps that: a mobile terminal detectsthe magnitude of the sound of a playing file every first preset time, and the audio output power of the corresponding mobile terminal is obtained according to the magnitude of the sound; the mobile terminal caches the obtained output power and corresponding timestamps and obtains audio output power EPC with the latest timestamp in the cached output power every second preset time; audio output power EPD set last time is obtained, and the output power EPD is compared with the output power EPC; and if the EPD is greater than the EPC, the audio output power is set to be EPD-1, and if the EPD is smaller than the EPC, the audio output power is set to be EPD+1. With the method of the invention adopted, the audio output power does not jump during playing; rapidly changing current can be preventedfrom interfering with the other modules of the mobile terminal; and the power outage-caused shutdown of the mobile terminal which is usually caused by the high possibility of the jump of battery instantaneous output current can be avoided.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an audio output power control method, a mobile terminal and a storage medium. Background technique [0002] At present, the emphasis on multimedia applications of mobile terminals is gradually increasing, and users have higher requirements for the sound quality and sound effects of mobile terminals. On the other hand, the use of audio is one of the most basic functions of mobile terminals. For example, traditional audio applications include incoming call ringtones and message ringtones. Later, with the increase in mobile terminal functions, audio applications involve all aspects of mobile terminals. For example, the sound played by video music, etc., and various high-quality sound effects. In actual use, when a mobile terminal plays a piece of music downloaded from the Internet, the original sound level of the file directly affects the output power of the audio ...

AI Technical Summary

Problems solved by technology

In actual use, when a mobile terminal plays a piece of music downloaded from the Internet, the original sound level of the file directly affects the output power of the audio circuit during the playback process. When the sound is high, the output power is high, and when the sound is low, the output power is high. However, if there is a sound in the middle of the music file that suddenly increases or decreases a lot, it will directly affect the rapid change of the playback power. The power change is reflected in the current. This kind of rapid current change can easily interfere with other devices module, on the other hand, the instantaneous output current jump of the battery is likely to cause the mobile terminal to power down and shut down
