Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing.

[0033] image 3 A schematic flowchart of the microphone control method provided by the present invention is shown. Such as image 3 As shown, the microphone control method includes:

[0034] S110. During the call, respectively acquire audio data of the primary microphone and the current secondary microphone;

[0035] S120. Periodically extract audio intensity information of the primary microphone and the current secondary microphone respectively from the audio data; and

[0036] S130. Determine an audio intensity ratio between the current secondary microphone and the primary microphone, and control switching of microphone combinations according to the audio intensity ratio.

[0037] The mobile terminal mentioned in this article can be any device capable of mobile communication, such as smart phones and tablet computers. Here, for the purpose of illustration, a smartpho...

Abstract

The invention provides a microphone control method of a mobile terminal and the mobile terminal, the mobile terminal comprises a main microphone and at least one auxiliary microphone, the microphonesused for noise reduction are combined into the main microphone and the current auxiliary microphone, and the method comprises the following steps: step 1, in a call process, respectively acquiring audio data of the main microphone and the current auxiliary microphone; 2, periodically and respectively extracting audio intensity information of the main microphone and the current auxiliary microphonefrom the audio data; and step 3, determining an audio intensity ratio of the current auxiliary microphone to the main microphone, and controlling to switch the microphone combination according to theaudio intensity ratio. By means of the method, whether the main microphone or the auxiliary microphone is blocked or not can be judged, if yes, the microphone combination used for noise reduction iscontrolled to be switched, and the optimal microphone noise reduction effect is achieved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and more particularly, to a method for controlling a microphone of a mobile terminal and the mobile terminal. Background technique [0002] At present, most smartphones on the market use the noise reduction method of the main and auxiliary microphones in the hand-held mode of the call, and perform noise reduction processing on the human voice before sending it to the remote end. Such as figure 1 As shown in the microphone layout of the mobile phone, the main and secondary microphone noise reduction principle is that the main microphone 1 is located at the bottom of the mobile phone, the first secondary microphone 2 is generally at the top of the mobile phone, and the second secondary microphone 3 is generally at the top of the back of the mobile phone. [0003] Due to the difference in the layout of the main and auxiliary microphones, the main microphone is closer to the human v...
