電腦接 音響內建的擴大機, 不是/不能直接接喇叭. 你要確定一下那個音響有沒有 3.5mm 的孔, 應該是標 mp3 link 吧!
查了一下... " Listen to an external device You can listen to an MP3 player through this Micro Hi-Fi. 1 Press MP3 LINK to select MP3 link source. 2 Use an MP3 link cable (supplied) to connect MP3 LINK jack (3.5mm) on this Micro Hi-Fi and the headphone jack on an MP3 player. "
