When the audio played by the speaker of the terminal (mobile phone, tablet computer, etc.) changes, it is generally necessary to add a ramp gain to the speaker, so that the volume of the audio played by the speaker changes from large to small, so as to ensure a smooth hearing. For example, when the audio played by the speaker of the terminal is switched from music to conversation, a slope gain needs to be added to the speaker, so that the volume of the audio played by the speaker is ensured to be changed from large to small, and the ears of a person are ensured to be not damaged.
At present, when the volume of the loudspeaker is controlled to be changed from big to small, the control gain which is usually added is a single slope control gain, but the slope of the single slope control gain is fixed, and when the volume of the loudspeaker is controlled to be changed from big to small, the change amount of the volume of the loudspeaker is fixed, so that the volume of the loudspeaker is firstly quickly reduced and slowly reduced in the process of changing the volume of the loudspeaker from big to small, and further, the smoothness of the hearing feeling of a user cannot be ensured. Meanwhile, when the playing audio of the loudspeaker is changed rapidly, the single-slope control gain cannot respond, so that the volume of the loudspeaker cannot be adjusted.
In order to solve the above problems, an embodiment of the present invention provides a volume control method, which is applied to a terminal, where the terminal in this embodiment may include a mobile phone, a tablet computer, a phone watch, etc., and steps of the volume control method in this embodiment are as shown in fig. 1, and include:

Specifically, in the process of changing the first audio to the second audio, if the volume of the first audio is smaller than that of the second audio, the volume change trend is that the volume is increased, and if the volume of the first audio is smaller than that of the second audio, the volume change trend is that the volume is reduced; in the process of changing from the first audio to the second audio and then from the first audio, if the volume of the first audio is smaller than that of the second audio, the volume change trend is that the volume is firstly increased and then decreased, and if the volume of the first audio is larger than that of the second audio, the volume change trend is that the volume is firstly decreased and then increased.

Specifically, the volume reduction process is adjusted into a first stage and a second stage, wherein in the first stage, the second audio volume is controlled to be rapidly reduced according to the first control gain, and in the second stage, the second audio volume is controlled to be slowly reduced according to the second control gain, so that the second audio volume can be rapidly reduced first, and the second audio volume can be slowly reduced.
In one example, if the volume reduction process is a volume first reduction in which the volume is first reduced and then increased, the volume first reduction portion is divided into a first stage in which the second audio volume is controlled to be rapidly reduced according to the first control gain and a second stage in which the second audio volume is controlled to be slowly reduced according to the second control gain; if the volume reduction process is volume reduction in the process of volume first increasing and then reducing, the volume post-reduction is divided into a first stage and a second stage, wherein in the first stage, the second audio volume is controlled to be rapidly reduced according to the first control gain, and in the second stage, the second audio volume is controlled to be slowly reduced according to the second control gain.

Specifically, the t1-t2 portion shown in fig. 2 is a stage of maintaining the speaker volume;
s103, in the process of increasing the volume, the volume is controlled to be increased according to the third control gain in the first stage, and then the audio volume is controlled to be increased according to the fourth control gain.
In the embodiment of the invention, the volume increase is controlled in stages according to the third control gain and the fourth control gain which are stored in advance, wherein the volume increase process comprises volume increase, volume increase in volume first decrease then increase and volume first increase in volume first increase then decrease, and the third control gain is smaller than the fourth control gain. Specifically, the volume adjustment is divided into a first stage and a second stage, wherein in the first stage, the second audio volume is controlled to be slowly increased according to the third control gain, and in the second stage, the second audio volume is controlled to be rapidly increased according to the second control gain, so that the second audio volume can be slowly increased first, and the second audio volume can be rapidly increased.
In one example, as shown in fig. 2, a control gain schematic diagram is provided in the embodiment of the present invention, where the preset control gain in the embodiment of the present invention includes a third control gain and a fourth control gain, the target gain (target volume) is greater than the initial gain (initial volume), the third control gain is a portion 0-t0 shown in fig. 2, the second control gain is a portion t0-t1, as can be seen in fig. 2, in the first portion 0-t0, the second audio volume is controlled to slowly increase according to the third control gain, in the second portion t0-t1, the second audio is controlled to rapidly increase according to the second control gain.
According to the volume control method provided by the embodiment of the invention, the change trend of the volume of the loudspeaker is determined when the audio data played by the loudspeaker is changed and the asking money is modified, the volume of the loudspeaker is reduced according to the first control gain in the first stage, the volume of the second audio is reduced according to the second control gain in the second stage, the volume of the second audio is increased according to the third control gain in the first stage in the volume increasing process, and then the volume of the second audio is increased according to the fourth control gain.

In one example, if the speaker changes from music playing to talking playing and the volume of the music playing is greater than the volume of the talking playing, the first initial volume corresponding to the volume decrease is the volume of the music playing, if the speaker changes from music playing to talking playing and then changes to music playing and the volume of the music playing is greater than the volume of the talking playing, the first initial volume corresponding to the volume decrease after the volume decrease is the volume of the music playing, and the first initial volume corresponding to the volume decrease after the volume decrease is the volume of the talking playing.

Specifically, during the first phase adjustment, the first initial volume is multiplied by the first control gain, and the first adjusted volume may be determined.
In one example, if the first control gain includes two first reduced sub-gains, in determining the first adjusted volume, a first intermediate adjusted volume of the first adjusted volume may be determined based on the first initial volume and the first reduced sub-gain, and the first adjusted volume may be determined based on the first intermediate adjusted volume of the first adjusted volume and the second first reduced sub-gain to determine the first adjusted volume.

Specifically, during the first phase adjustment, the first adjustment volume is multiplied by the second control gain, and the second adjustment volume may be determined.

In one example, as shown in fig. 3, the number of the second control gains may be 1, and when the first adjustment volume is determined according to the second control gain, the first adjustment volume is multiplied by the second control gain, so that the second adjustment volume may be determined.
In one example, the first reduced sub-gain is greater than the second reduced sub-gain, i.e., the rate of reduction of the volume of the second audio of the speaker in the first phase is greater than the rate of reduction in the second phase.
When the volume change trend is volume reduction, the embodiment of the invention adjusts the second audio volume in stages through the first control gain and the second control gain, and can smoothly adjust the volume of the loudspeaker, thereby ensuring smooth hearing of a user and improving user experience.
