JRC4558电路类别:电子综合阅读:4570工作原理,如图纸所示:主要分为三部分。
分别为电源电路、卫星箱功放电路、超重低音电路.一、电源电路(图纸的最下面部分):220V市电经过保险管(F),和开关S后进入变压器初级,变压器的次级输出双12V交流,双12V送入由VD1组成的桥式整流电路电路,经过桥式整流和C14,C15(330 0UF/25V)的滤波后,输出的空载电压约为正负16V左右(根号2乘于12V),即A+为正16V,A-为负16V。
正负1 6V为三块功放芯片TDA2030,UTC2030提供电源。
另一路经过R21、R22的降压后,由B+,B-输出约正负12V 为低音前置放大和低通滤波器IC4提供电源电压。
在本图纸当中,前置放大的供电并没有采用78/7912三端稳压电路,磨机爱好者在更换两个33 00UF电容时,也可以考虑加入LM7812/7912为前置提供更为稳定的工作电压。
二、左右声道放大电路(卫星箱功放电路),因左右声道作原理完全一致。
这里我只以图纸的左声道为例,作个介绍。
如图:RIN为信号输入端,经过耦合电容C23进入音量电位器,(音量电位器由三个引脚,与C23连接的是输入端,输出端也叫滑动端、另一引脚为接地端),调整音量后信号进入由R1/C3组成的高音提升电路,此电路可以提升一定量的高频信号,使声音更加清晰。
尔后信号经过耦合电容C1进入左声道功放,型号为UTC2030的1脚,经过功率放大后,由2030的第四脚输出,推动卫星箱发声。
图中的R7为反馈电阻,R7/R9为决定2030芯片的放大倍数。
因此,调整R7的阻值,就可以调整放大倍数。
R11/C7为扬声器补偿网络。
三、超低音电路。
由左右声道经两个10K电阻R5、R6后至C11耦合电容,尔后信号进入IC4,型号为JRC4558的3脚,图中IC4A为超低音的前置放大器。
R201T将此放大器的放大倍数设置为6倍左右。
(R17/R18),经过前置放大后,才能保证足够大的驱动电压,获得足够大的音量。
