另一个麦克风物理主动消除噪音，通过收集外界的声音，进行处理后，发出与噪

Another physical microphone active noise cancellation, by collecting external sound, post-processing, and noise emitted opposite sound waves, using the offset principle to eliminate the noise, thereby to extract more pure noise-free sound.

Another microphone physically actively eliminates noise by collecting external sounds, which, after processing, emits the opposite sound waves to the noise, using the cancellation principle to eliminate noise and thus extract inglier, noise-free sounds.

Another microphone physically actively eliminates the noise. By collecting the external sound and processing it, it emits the sound wave opposite to the noise. By using the cancellation principle, the noise is eliminated, so as to extract a purer and noiseless sound. This article is from MTK mobile network http://www.mtksj.com<br>
