Claim Text:
1. A method for reproducing audio signals using an electronic device, the electronic device comprising an audio amplifier, a speaker, a storage device, and at least one processor, the method comprising: decoding an audio file stored in the storage device to generate original digital audio signals; attenuating the original digital audio signals having frequencies that are lower than a preset cutoff frequency and acquiring attenuated digital audio signals, outputting the attenuated digital audio signals and the original digital audio signals having frequencies that are higher than the preset cutoff frequency; amplifying each of the attenuated digital audio signals and the original digital audio signals with a preset gain and acquiring amplified digital audio signals, wherein the preset gain is equal to a sound intensity difference between a standard audio signal and a signal having the greatest sound intensity among the attenuated digital audio signals and the original digital audio signals, wherein an sound intensity of the standard audio signal is equal to 0 dB; and converting all the amplified digital audio signals into analog audio signals, and outputting all the analog audio signals to the audio amplifier, the audio amplifier amplifying the analog audio signals to drive the speaker to output the analog audio signals.
