and step 10, acquiring the noise value of the environment and crowd information within a preset distance range.
Step 10 may be performed by obtaining a noise value of an environment where the electronic device is located in any manner, and obtaining crowd information within a preset distance range of the electronic device in any manner.
For example, in one embodiment of the present application, as shown in FIG. 2, step 10 of obtaining the noise value of the environment may include:
and 11, acquiring sound information acquired by at least one microphone in the electronic equipment.
The sound information may include size information of sound, direction information of sound, or other information, among others.
Step 12, determining a noise value according to at least one sound information.

step 40, reducing the volume of the target speaker in the case that the movement direction of at least one person in the crowd is the direction toward the electronic device or the number of persons increases.
When the moving direction of at least one person in the crowd is the direction towards the electronic device or the number of people increases, the privacy of the environment where the electronic device is located is shown to be poor, and at this time, the volume of the target speaker is reduced through step 40, so that the crowd (including at least one person with the direction towards the electronic device as the moving direction) in the environment where the electronic device is located can be ensured to be unable to hear the speaker to play sound, the privacy of the user is protected, and the use experience of the user is improved.
Step 50, maintaining the volume of the target speaker or increasing the volume of the target speaker in the case that the movement direction of each person in the crowd is away from the electronic device or the number of people is reduced.
When the moving direction of each person in the crowd is the direction deviating from the electronic equipment or the number of people is reduced, the privacy of the environment where the electronic equipment is located is shown to be good, at this time, the volume of the target speaker is maintained or the volume of the target speaker is increased through the step 50, so that the crowd in the environment where the electronic equipment is located can be ensured to be unable to hear the speaker to play sound, the privacy of the user is protected, and the audio experience of the user is improved.
Optionally, when the number of people decreases to zero, the target speaker may be a speaker close to the user in the electronic device, and the speaker direction of the target speaker is a first direction facing the user, and the target speaker is all speakers in the electronic device, and the speaker direction of the target speaker is all directions.
Optionally, in a specific embodiment of the present application, as shown in fig. 2, the control method may further include:
step 60, if the noise value is greater than the first preset value and the number of people is zero, if the audio mode of the target speaker is the left and right channel audio mode, switching the audio mode of the target speaker to the mono audio mode.
