The processor executing the headset calibration method may be installed in the first headset or the second headset; the method can also be installed in mobile terminals, such as mobile phones, tablets and other terminals. Before the earphones leave the factory, or when the user finds that the loudness of the first earphones and the second earphones are inconsistent, the calibration of the earphones can be performed through the steps S1 to S4. The earphone is connected with the mobile terminal communication, when the earphone needs to be calibrated, a calibration instruction can be sent out from the mobile terminal, the mobile terminal opens the audio loop switch, the control earphone enters a calibration mode, the mobile terminal continuously sends a preset calibration audio signal to the earphone, the earphone plays a corresponding audio frequency, in the calibration mode, only one earphone of the first earphone and the second earphone is in an open state at the same moment, the other earphone is in a closed state, and the first sound acquisition device and the second sound acquisition device acquire corresponding sound information according to a preset acquisition sequence.
In step S1, the first sound collection device and the second sound collection device may be microphones, and the first sound collection device and the second sound collection device are symmetrically disposed on the first earphone and the second earphone to avoid interference of distance factors. The first sound collection device and the second sound collection device collect sound information independently from each other. The first sound information comprises audio played by a first earphone, and the second sound information comprises audio played by a second earphone; or the first sound information comprises the audio played by the second sound earphone, and the second sound information comprises the audio played by the first earphone. The sound collected by the first/second sound collection devices may include ambient noise in addition to the audio played by the headphones. Therefore, when performing earphone calibration, it is preferable to perform earphone calibration in a quiet environment to avoid acquiring an ambient noise signal, and when in a specific quiet environment, it may be considered that the first sound information is an audio played by a first earphone and the second sound information is an audio played by a second earphone; or the first sound information is the audio played by the second earphone, and the second sound information is the audio played by the first earphone.

if not, adjusting the volume value of the earphone to the maximum volume value.
6. The headphone calibration method as recited in claim 5, wherein the step of adjusting the gain output of the first headphone and/or the second headphone to cause the loudness difference to be less than the preset difference comprises:
setting a volume value of the headset to a default volume value.
7. The method of calibrating a headset according to claim 6, wherein the step of setting the volume value of the headset to a default volume value is preceded by the step of:
extracting a set volume value corresponding to the maximum use time from a historical volume database of the earphone, and taking the set volume value corresponding to the maximum use time as the default volume value, wherein the set volume value and the use time are stored in the historical volume database in a correlation manner, and the use time is the use time of the earphone under the set volume value.
8. An earphone calibration device, wherein the earphone comprises a first earphone and a second earphone, the first earphone is provided with a first sound collection device, the second earphone is provided with a second sound collection device, the earphone calibration device comprises:
the acquisition unit is used for sequentially acquiring first sound information acquired by the first sound acquisition device and second sound information acquired by the second sound acquisition device;
a calculating unit configured to calculate a loudness difference between the first sound information and the second sound information;
the judging unit is used for judging whether the loudness difference value is smaller than a preset difference value or not;
and the adjusting unit is used for adjusting the gain output of the first earphone and/or the second earphone if the loudness difference is smaller than a preset difference value, so that the loudness difference value is smaller than the preset difference value.
9. An intelligent terminal comprising a memory and a processor, the memory having stored therein a computer program, characterized in that the processor, when executing the computer program, implements the steps of the method according to any one of claims 1 to 7.
10. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the method of any one of claims 1 to 7.
