CD激光唱机诞生于80年代,虽然历经了LD、VCD、SVCD以及DVD诸多新产品的冲击,但是由于CD机在播放音乐上有其独特的特点,在机制上也较其它新机型更为完善,放各厂家仍在不断推出新品。山灵HDCD-12就是当今高品质国产CD播放机之一。 HDCD-12虽是一款合并式CD机,但它的设计理念是分体式的。打开机盖观其内部,机箱左边是两只电源变压器(分别是数字和模拟电路的电源),各用精美的铁壳封闭,以防磁场干扰主电路。机箱中央是CD转盘,同样用铁壳屏蔽以杜绝射频信号的干扰。这种做法相当考究,即使在进口高档机中也是不多见的。 机箱右边是电路部分,有两块双面喷锡电路板,一块是整
CD CD player was born in the 80s, although after the impact of LD, VCD, SVCD and DVD many new products, but because of the CD player has its own unique music features, the mechanism is more perfect than other new models , Put the manufacturers are still constantly introducing new products. Mountain Spirit HDCD-12 is one of today’s high-quality domestic CD player. Although HDCD-12 is a merged CD player, but its design concept is split. Open the lid to see the inside, the left side of the chassis are two power transformers (digital and analog circuits are the power supply), each with a beautiful iron enclosure to prevent the magnetic field interfere with the main circuit. CD turntable is the center of the chassis, the same shield with iron to eliminate radio frequency interference. This approach is quite elegant, even in the import of high-end machine is rare. The right part of the circuit is the circuit part, there are two double-sided spray tin circuit board, one is the whole
