Abstract:
1. A computer system including a main system having an audio signal generating unit generating audio signals, a main audio outputting unit in communication with the main system and outputting the generated audio signals, an auxiliary system connected to the main system and receiving the generated audio signals, and an auxiliary audio outputting unit in communication with the auxiliary system and outputting the generated audio signals received in the auxiliary system, the computer system comprising: a first filter provided in the main system, filtering the audio signals generated in the audio signal generating unit and supplying only a first frequency band as designated to the main audio outputting unit; a second filter provided in the auxiliary system, filtering the audio signals generated in the audio signal generating unit and supplying a second frequency band different from the first frequency band to the auxiliary audio outputting unit; a third filter provided in either of the main system or the auxiliary system, filtering the audio signals generated from the audio signal generating unit and supplying a third frequency band different from the first and the second frequency bands to either of the main audio outputting unit or the auxiliary audio outputting unit; and a switching unit switching the audio signals to selectively pass through either the first filter or the third filter and be supplied to the main audio outputting unit, and to selectively pass through either the second filter or the third filter and be supplied to the auxiliary audio outputting unit, depending upon whether the auxiliary system is connected to the main system.
