Fig. 1 is a flowchart of a volume adjustment method according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
s101, acquiring the target volume of the current environment of the terminal equipment.
The terminal equipment can select sound play for playing audio, video or answering a call, and the like, under the condition, environmental noise is one of important factors influencing the play volume, when the environmental noise is large, the play volume is correspondingly increased, so that a user can be ensured to clearly hear the play sound, and when the environmental noise is small, the play volume is correspondingly reduced, so that the influence on the periphery is reduced. Therefore, in order to obtain an accurate volume for external sound, it is necessary to refer to the volume of the environment in which the terminal device is currently located.

Optionally, the volume of the current environment of the terminal device may be detected for multiple times to obtain multiple candidate volumes, and then an average value of the candidate volumes is obtained as the target volume of the current environment of the terminal device.
Alternatively, the terminal device may be a hardware device with various operating systems, such as a mobile phone, a tablet computer, a personal digital assistant, a wearable device, and the like.
S102, obtaining the distance between the user and the terminal equipment.
The distance between the user and the terminal equipment is also one of factors influencing the target play-out volume, when the distance is longer, the play-out volume is correspondingly increased, so that the user can clearly hear the play-out volume, and when the distance is shorter, the play-out volume is correspondingly reduced, so that the influence on the periphery is reduced. Therefore, in order to obtain accurate play volume, the distance between the user and the terminal device needs to be referred.

As a possible implementation manner, a mapping function with the target volume and the distance as inputs may be constructed, and the target play-out volume of the terminal device is determined by the mapping function. Alternatively, the mapping function may be as follows:
r=f(Ve,le)
wherein r is the target playback volume, f (V)e,le) Indicating information about target volume VeAnd a distance leThe mapping function of (2).
After the target volume and the distance are acquired, the target volume and the distance can be input into a mapping function, and the target volume for playing out is acquired.
