A game controller includes a housing, a number of press sensors and touch sensors, and a main circuit embedded in the housing powered by a battery. The main circuit includes a collecting module, a comparing module and a controlling module. The press sensors detects pressure from the housing and outputting a number of pressure signals. The touch sensors detects a plurality of touch signals. The collecting module collects and combines the pressure signals and the touch signals into a first positioning signal and a second positioning signal correspondingly. The comparing module predetermines a number of preset signal values and a number of preset pitches correspondingly and compares the first and second positioning signals with the preset signal values. The controlling module triggers one of the preset pitches when the first positioning signal and the second positioning signal are equal to the preset signal values.
