Abstract
In addition to output the mid-high range audio sound from the speakers of the main unit, the present invention can output the low range audio sound according to the audio signal transmitted from the main unit through the DC power supply transmission cable from the sub-woofer unit of the AC adapter. Accordingly, the present invention can provide a richly expressive acoustic space without enlarging the size of the main unit.
