Claim:
1. A frequency response compensation method, adapted to an electronic device having a first speaker and a second speaker, wherein the first speaker and the second speaker are not coplanarly disposed on the electronic device, and wherein the method comprises: inputting a stereo audio signal respectively into a high-pass filter and a low-pass filter to generate a high-frequency right-channel signal, a high-frequency left-channel signal, a low-frequency right-channel signal, and a low-frequency left-channel signal; performing sound-field processing on the high-frequency right-channel signal and the high-frequency left-channel signal to generate a modified high-frequency right-channel signal and a modified high-frequency left-channel signal; performing sound-field processing on the low-frequency right-channel signal and the low-frequency left-channel signal to generate a modified low-frequency right-channel signal and a modified low-frequency left-channel signal; and outputting the modified high-frequency right-channel signal and the modified low-frequency right-channel signal to the first speaker and outputting the modified high-frequency left-channel signal and the modified low-frequency left-channel signal to the second speaker, wherein the modified high-frequency right-channel signal and the modified high-frequency left-channel signal are outputted diffusely by the first speaker and the second speaker, and wherein the modified low-frequency right-channel signal and the modified low-frequency left-channel signal are outputted centrally by the first speaker and the second speaker.
