Publication number: 20170180533Abstract: A microphone switching method and system for a mobile terminal is provided. When the mobile terminal detects that an incoming call is received, an angle and position information of the mobile terminal is obtained and whether the mobile terminal is placed upside down is determined according to the angle and position information. If yes, the function of a first microphone disposed on an upper portion is switched to receive a voice signal and the function of a second microphone disposed on a lower portion is switched to receive the noise signal. In this way, even though the mobile terminal is placed upside down, a user can still make voice communications well using the mobile terminal.Type: ApplicationFiled: April 7, 2016Publication date: June 22, 2017Inventor: Qiong CHEN
