发明名称 Sound device for expansion station
摘要 A sound device includes a silent state detecting unit for detecting a silent state in a sound signal supplied by a personal computer; and a sound production preventing unit for preventing a sound from being produced from the sound signal supplied by the personal computer when the silent state is detected by the silent state detecting unit. By halting the production of a sound from the sound signal supplied from the personal computer when the silent state is detected, production of noise in a silent state is prevented so that the quality of sound in the expansion station is improved.
