Sound acquisition method applied to MT (Mobile Terminal) and MT

Abstract

The invention discloses a sound acquisition method applied to an MT (Mobile Terminal) and an MT. The MT is provided with more than two microphones. The sound acquisition method comprises the steps of triggering the more than two microphones to acquire sound when an application needing to acquire the sound is started; determining a microphone closest to a sound source according to the sound acquired by the more than two microphones; determining the microphone closest to a sound source to be a main microphone, and determining other microphones of the more than two microphones to be secondary microphones; carrying out noise reduction on the sound acquired by the existing main microphone determined by the sound acquired by the existing terminated secondary microphones; and outputting the sound after the noise reduction. According to the technical scheme provided by the invention, the sound acquisition quality can be effectively improved.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a sound collection method applied to a mobile terminal and the mobile terminal. Background technique [0002] With the rapid development of mobile communications, mobile phones have become an important tool for people to communicate in daily life, but some problems encountered in actual use have always puzzled mobile phone designers. For example, when the user is in a noisy environment, or in a meeting where other people are required to participate in a mobile phone conversation, it is often necessary to use the hands-free calling function of the mobile phone, and for most mobile phones, especially for some For mobile phones with loud speakers, the actual effect of hands-free calls is usually not satisfactory. The quality of calls is often affected by the howling and echo generated by the mobile phone, making the quality of hands-free calls poor, which makes hands-free calls, whic...

[0002] With the rapid development of mobile communications, mobile phones have become an important tool for people to communicate in daily life, but some problems encountered in actual use have always troubled mobile phone designers

For example, when the user is in a noisy environment, or in a meeting where other people are required to participate in a mobile phone conversation, it is often necessary to use the hands-free calling function of the mobile phone, and for most mobile phones, especially for some For mobile phones with loud speakers, the actual effect of hands-free calls is usually not satisfactory. The quality of calls is often affected by the howling and echo generated by the mobile phone, making the quality of hands-free calls poor, which makes hands-free calls, which are very difficult It is difficult to realize the original design intention of the humanized function
