《家庭电子》1998年第10期发表的《随身听电源插口的改制》一文,构思独特。笔者采用另一种方法,对随身听电源插口进行了改进,收到了满意的效果,现介绍如下。具体作法:将图1中“×”处断开,接入一只27Ω/1W的电阻,在输出端(OUT)接一只稳压管DW,其稳压值视随身听工作电压而定。改进后的电路原理如图2所示。这样也能基本消除外接电源产生的交流声。若结合第10期《随身听电源插口的改制》一文的方法,在图中②、③之间接入一只 “Home Electronics” 1998 the tenth issue of “Walkman power socket restructuring” a unique concept. I use another method, the power cord to the Walkman has been improved, received a satisfactory result, are presented below. Specific approach: Figure 1, “×” at the disconnect access to a 27Ω / 1W resistor, the output (OUT) connected to a Zener tube DW, the regulator value depending on the operating voltage of the player may be. Improved circuit shown in Figure 2. This also can basically eliminate the hum of the external power supply. If combined with the first 10 “Walkman power outlet restructuring,” a text method, in the figure between the two, ③ access
