Abstract
In a method of reproducing audio signals using an electronic device, the electronic device decodes an audio file to generate original digital audio signals, and attenuates the original digital audio signals having frequencies that are lower than a preset cutoff frequency. The electronic device further amplifies each of attenuated digital audio signals and the original digital audio signals having frequencies that are higher than the preset cutoff frequency with a preset gain. Once the electronic device converts the amplified digital audio signals into analog audio signals, and outputs the analog audio signals to an audio amplifier, the audio amplifier amplifies the analog audio signals to drive a speaker to output the analog audio signals.
