METHOD FOR CONTROLLING DUAL-MICROPHONE NOISE CANCELLATION OF MOBILE PHONE AUTOMATICALLY AND MOBILE PHONE

摘要

Disclosed are a method for controlling dual-microphone noise cancellation of a mobile phone automatically and a mobile phone. The method comprises steps: when a mobile phone is in calling state, automatically detecting the distance from a front side of the mobile phone to the ear of a user in real time by using a proximity sensor installed inside the mobile phone, and comparing detected distance information with a preset value; if the detected distance is less than or equal to the preset value, automatically performing controlling to enable a dual-microphone noise cancellation function of the mobile phone; if the detected distance is greater than the preset value, automatically performing controlling to disable the dual-microphone noise cancellation function of the mobile phone. Using the preset invention, the user only needs to approach the mobile phone to the ear normally to call clearly in a noisy environment; and field sound can be transmitted to a peer party once the mobile phone is moved away from the ear when background sound is needed. No hardware element needs to be added, the noise cancellation effect is desirable, and convenience is brought to the user.
