Abstract: A mobile terminal and a mobile terminal audio signal processing system including the same are disclosed. The mobile terminal includes a first body including an opening, a main circuit board, and a main earphone jack, a first audio signal processing body including a first circuit board, on which a sub-sound module receiving a digital audio signal from the first body and converting the digital audio signal into an analog audio signal is mounted, and a sub-earphone jack outputting the analog audio signal, and a controller outputting a first audio signal to the sub-earphone jack and outputting a second audio signal to the main earphone jack. The first audio signal processing body is a first state where the first audio signal processing body is coupled with the opening, or a second state where the first audio signal processing body is separated from the first body.
