AbstractAn apparatus and a method for outputting an audio signal of a laptop computer to a first speaker in the laptop computer and a to second speaker in a docking station are provided. The apparatus includes a first controller implemented in the laptop computer for filtering a high frequency band component and a low frequency band component from the audio signal, for mixing the filtered signals, and for outputting the mixed signal to the first speaker when the laptop computer is not coupled with the docking station, and otherwise, filtering only a high frequency band component from the audio signal and outputting the filtered signal to the first speaker. A second controller is implemented in the docking station for receiving the audio signal from the laptop computer, for filtering a low frequency band component from the received audio signal, and for outputting the filtered signal to the second speaker when the laptop computer is coupled with the docking station. When the laptop computer is coupled with the docking station, the audio signal generated in the laptop computer is divided into high and low frequency band signals, and each divided signal is output to different speakers according to the characteristics of the divided signals. Thus, efficiency in use of the speakers and sound quality are improved.
