A stereo music card includes a card(1), a circuit board(2) disposed thereon, a dual-channel chip(21) in the board(2), and two speakers(3) connected to the chip(21). Said card(1) may have two pages(11,12) or three pages(11,12,13), so two speakers(3) could be both installed in the interlayer(11) of the two-page card or be installed respectively on two lateral pages(11,13). The two speakers(3) could attain good stereo acoustics. |
