计算机有源音箱的设计

就计算机有源音箱电路的设计,分别介绍了双电源电路、双声道立体声电路、超重低音电路以及静噪和保护电路的设计方法.提出了若干设计理念:如电源设计中采用简单串联武稳压,提高了设计的灵活性;双声道立体声前置采用反相放大形式,可有效减小噪声,提高信噪比;超重低音电路采用独有的高低通滤波器进行分频,可有效减小低频噪声,使超重低音浑...

Design of Computer Active Speakers

To the design of computer active speakers, the dual power supply circuit, double track stereo circuit, the mega bass circuit and static and protect circuit design method are introduced. Details of circuit are proposed by own designing concept. If power supply voltage applies to the design of simple design, flexibility is increased. Reverse phase is applied in double track stereo lead by, it can effectively reduce amplifier noise and improve the signal-to-noise ratio. The mega bass circuit adopts unique high-low frequency filter, the low-frequency noise can be effectively reduced, and the mega bass is vigorously strong and does not tolerate. This set of circuit is practically tested, it has this effect with the little-distortion degree, highly clear and median permeability, bass strong shock.
