Preferably, when the volume selected by the user is a certain amplitude grid such as 8 in the preset range, the volume is directly adjusted to the amplitude grid 8 when the volume needs to be reduced next time, so as to meet the requirement of the user more accurately.
In the third embodiment, based on the first embodiment, the step S3 further includes:
and when the audio parameters are smaller than the corresponding preset parameters, increasing the volume of the earphone to the preset range.
In this embodiment, it is assumed that the volume of the earphone includes 20 amplitude grids from mute to maximum, and the volume at the 8 th to 10 th amplitude grids is just suitable for the user, and the corresponding volume preset range is 8-10. Of course, it is understood that in other embodiments, the preset range of the volume may be characterized by other parameters, and the volume most suitable for the user is not limited to the specific examples described above.
Assuming that the audio parameters include loudness and frequency, when it is detected that the loudness in the ear cavity of the user is less than a preset loudness, for example, 40dB, and/or the frequency is less than a preset frequency of 3KHz, the volume of the earphone needs to be increased to a preset range, for example, 8-10 amplitude grids.
Preferably, when the volume selected by the user is a certain amplitude grid such as 10 in the preset range, the volume is directly adjusted to the amplitude grid 10 when the volume needs to be increased next time, so as to more accurately meet the requirements of the user.

Specifically, the wearing detection unit may be a pressure sensor, and whether the earphone is in a wearing state or a tightness state is determined according to a pressure value detected by the pressure sensor. When the pressure value detected by the pressure sensor is greater than a preset threshold value, the machine can be judged to be in a wearing state. Further, the range interval where the pressure value is located is judged, if the pressure value is in a first range interval, it can be judged that the earphone is in a wearing and loosening state, and if the pressure value is in a second range interval, it can be judged that the earphone is in a wearing and tightening state, wherein the range value of the second range interval is larger than the range value of the first range interval.
And step S5, carrying out self-adaptive adjustment on the volume of the earphone according to the wearing state of the earphone.
In this embodiment, when the wearing state is a tight wearing state, the volume of the earphone is controlled to be decreased by a predetermined value. This scheme may be performed after the earphone volume adjustment is performed in the first embodiment, or may be performed simultaneously with the scheme of the first embodiment. Specifically, when the earphone is in a tight wearing state, the preset volume value of the earphone is reduced by 10%; when the wearing state is a wearing loose state, the volume of the earphone is increased by a preset value, such as 10%.
