As shown in FIG. 1 , the method for ending a call includes the following steps: Step 101: After the call is connected, according to the collected sound data of two or more microphones, it is determined whether the mobile terminal currently has a local input volume of the call. And determining, according to the collected sound data of the earpiece, whether the mobile terminal currently has a volume input by the other party of the call;

Here, the determining, according to the sound data of the two or more microphones collected, the mobile terminal Whether there is a local input volume of the call before, including:

Determining, in the first preset time period, whether the at least one average sound level value of the set of the difference between the average sound level values of the main microphone and each of the auxiliary microphones is greater than or equal to the first one of the collected sound loudness values of the two or more microphones a threshold, determining that the local input volume of the call is determined to be within the first preset time period when the difference in the average acoustic sound value of each of the combinations is greater than or equal to the first threshold in the first preset time period When the difference in the average acoustic sound value in the set is less than the first threshold, the local input volume of the call is considered to be absent.

Wherein, the difference between the average acoustic sound value of the primary microphone and the secondary microphone is used to determine whether the local input volume of the call is based on:

The main microphone refers to: the received input volume is mainly the microphone and background noise of the input volume of the party holding the mobile terminal, and the main microphone is generally located at the bottom of the body of the mobile terminal; the auxiliary microphone refers to: The input volume received is mainly background noise, which is generally located beside the headphone jack on the top of the mobile terminal body. The input volume of the main microphone during the call is mainly the input volume of the party holding the mobile terminal, and the auxiliary microphone is The input volume is mainly background noise, and the difference between the acoustic sound value of the main microphone and the acoustic sound value of the auxiliary microphone can be regarded as the input volume of the mobile terminal by the party holding the mobile terminal. Therefore, the main input can be utilized. The distance between the microphone and the auxiliary microphone and the sound source during the call is to open the input volume of the two microphones, so that the local input volume of the call can be judged according to the difference between the average sound level values of the main microphone and the auxiliary microphone.

The first preset time period can be set as needed, such as: 1 minute, and the like. In practical applications, assuming that the first preset time is 1 minute, the sound and sound values of the three or more microphones can be collected in one minute, and the acoustic sound value of each of the collected main microphones and each auxiliary microphone is taken. Value, and average the difference between the sound and the sound of the main microphone and each of the auxiliary microphones obtained three times, thereby obtaining the difference between the average sound and the sound value of the main microphone and each of the auxiliary microphones, for example,

4叚 has three microphones, which are the main microphone 1, the first auxiliary microphone 2 and the second auxiliary microphone 3, respectively. Taking the difference between the sound and sound values collected by the main microphone 1 and the first auxiliary microphone 2, respectively, and obtaining the first sound sound difference value, the second sound sound level difference, and the third sound sound difference value respectively; The difference value, the second sound level difference, and the third sound level difference are averaged, that is, the average sound level difference between the main microphone 1 and the first auxiliary microphone 2 is obtained; for the same reason, the main microphone 1 and the second are The acoustic sound value collected by the auxiliary microphone 3 takes a difference, and respectively obtains a fourth sound sound difference value, a fifth sound sound level difference, and a sixth sound sound degree difference; the fourth sound sound difference value and the fifth sound sound degree difference are respectively obtained. The value and the sixth acoustic sound difference are averaged, that is, the average acoustic sound value difference between the primary microphone 1 and the second secondary microphone 3 is obtained. Here, the specific processing procedure of collecting the sound data of the microphone is a technical means conventionally used by those skilled in the art, and details are not described herein again.

The set includes an average acoustic sound value difference between the primary microphone and each secondary microphone. For example, if there is a primary microphone, a first secondary microphone, a second secondary microphone, and a third secondary microphone, the set includes: a difference between the average acoustic sound value of the primary microphone and the first secondary microphone, and a primary microphone and The difference between the average acoustic sound value of the second auxiliary microphone and the average acoustic sound value of the primary microphone and the third secondary microphone.

The local input volume of the call refers to: a call volume of a person input by the mobile terminal in a direction of the mobile terminal.

The determining, according to the sound data of the collected earpiece, whether the mobile terminal currently has a voice input volume of the call, specifically:

Determining whether the average sound level of the collected earpiece is greater than or equal to a second threshold value during the second preset time period, and determining that the average sound level of the earpiece is greater than or equal to the second threshold value during the second preset time period If the mobile terminal currently has the input volume of the call, and determines that the average sound level of the handset is less than the second threshold during the second preset time period, it is considered that the mobile terminal does not currently input the volume of the call. The second preset time period can be set as needed, for example: 1 minute, and the like. The second threshold may be set as needed, for example, the background noise of the handset may be set to be up to a third threshold, wherein the third threshold may be set according to requirements, for example, set to five decibels; The background noise of the earpiece refers to the noise of the earpiece itself, in other words, the noise generated by the earpiece itself after being activated.

In practical application, if the acoustic sound value of the earpiece is collected three times in the second time period, the acoustic soundness values of the three acquired earpieces are averaged, that is, the second preset time period is obtained. The average sound level of the earpiece collected within. Here, the specific processing procedure for collecting the sound data of the earpiece is a technical means conventionally used by those skilled in the art, and details are not described herein again.

Correspondingly, the input volume of the other party of the call refers to: a call volume of a person input by the mobile terminal that does not hold the mobile terminal in the direction of the mobile terminal.

In practical applications, the location of the two or more microphones at the mobile terminal can be determined according to the needs of the mobile terminal itself and in combination with acoustic principles.
