Abstract

A media player capable of automatically adjusting equalizer parameter thereof is provided. 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.

Dependent claims

A media player capable of automatically adjusting equalizer parameters thereof, comprising:

a memory configured for storing equalizer parameters of the media player;
a speaker configured for outputting audible sounds;
an earphone jack configured for connecting an earphone to output the audible sounds;
a switch configured for disconnecting the speaker from outputting the audible sounds when the earphone jack is inserted in the earphone;
a detecting circuit configured for detecting a voltage of the speaker or of the switch and obtain a detected voltage value;
and
a processor configured for comparing the detected voltage value with predetermined voltage values, determining whether the speaker or the earphone is used to output the audible sound according to the comparison result, and selecting corresponding equalizer parameters suitable for the speaker or the earphone to output the audible sounds.
