改装汽车收音机
我想起来还有个收音机可以玩那个已经放好久了那个是上个学期拿回来了东西了我就对着那个接口看（图1）我看见那两个大的触点就感觉不对劲这绝对是接正负极的我就看图2那个接口的说明看那个20号是gnd 19号是+我就想我果然猜对了我就想焊但是空间不够我就把整个接口想破坏但是接口的强度太大弄不坏我就把螺丝拧下来把盖子撬开在里面给后面的触点上锡我发现烙铁头上的锡没法上锡给触点上锡我把电线焊上我发现不能打开我想是电源电流不够才3A我换了一个6A的还不想我想是因为这个电源的电是一闪一闪的那种我换个10A的还不行我想是我的原因我就继续看接线的说明我发现了ACC发现之后很高兴结果我把负极接过去了我弄了半天才发现还好没有烧我把bat+上的正极接ACC上负极接gnd还是不行我就想BAT+这个触电这么大是不是ACC和BAT+要连一起接正极我就剪了一小段锡线连上了打火星了我但是开机了应该是电容的原因然后我找喇叭的接线就看见了fr和rr我猜这是四个声道对于移动设备来说4声道很多但是对于车来说已经是很低端的了我就接了23号线接上去杂波很大我就用还剩很多不知道多少平方的线做天线线一头连收音机另一头放窗户外面了http://image.rcfans.com/pic/20220612/1655001784224238_481.jpg?x-oss-process=image/watermark,image_cGljLzIwMjExMDA2L29zc18xNjMzNTM0ODIxOTgzXzg2NF81MzNfNTYucG5n,t_50,g_se,x_20,y_20

这回就都焊好了往上焊了一个音频线延长线把平板扬声器为了找地方把音频线弄出来还不打孔我把装屏幕的后面的金属盖板反过来了在左边的下面刚好有一个可以让线出去把盖板反过来就好了在塑料边框上切一下就ok了往上焊了一个路由器的天线
