The media player includes a speaker, a processor, a memory, an audio amplifier, a decoder, an analog to digital (D/A) converter, an earphone jack for connecting with an earphone, a switch and a detecting circuit. The memory stores audio files and a voltage value-equalizer parameter look-up table. The detecting circuit detects a voltage of the speaker or the second dynamic contact of the switch and obtains a voltage value. The processor compares the voltage value with predetermined voltage values and obtains a comparison result, and reads corresponding equalizer parameters from the table according to the comparison result. The media player plays an audio files according to the equalizer parameters, thus to obtain audio effect optimization.
