【原创】 DIY胆石数字收音机 RDA芯片 【源代码+图】
http://cache.amobbs.com/bbs_upload782111/files_25/ourdev_529797.jpg(原文件名:1.jpg)
使用RDA调谐芯片的收音机,
功能:收听FM广播
创新点:受不了晶体管广播干巴巴的声音,利用电子管声效处理,声音变得圆滑耐听。
本收音机结合了电子管的音效圆滑处理(可以滤除电台高频噪音),又结合了晶体管的大功率特性。
因直接近CD音质、上次家人在看书,广播里正在播好听的管弦乐,爸爸问我这是什么CD?这么好听,
我说这是广播……

收音机模块和放大其实可以拆分的,可以看到收音机内部有铁壳屏蔽,里面是收音芯片。

中间则是供电电路高压部分,有点危险,设置了放电按键,注意看有一块被黑色胶布贴起来的就是按钮。
长时间不用时,按此键3秒即可放掉阳极供电线路里剩余的电。

收音机背面自带了一个“轻量级的”功放,采用TDA2822芯片,输出1w功率,外出使用时方便使用。
天线可拆卸,上图天线为便携式天线,在家时可接上八木天线。

通过上、下、加、减、来完成一系列操作。设有耳机孔。

变压器设在底部,尽量远离放大电路,以防引入干扰。

这是菜单,屏幕左面为实时监视器,可以看到信号强度、电台立体声或者单声道、频率、TUNE(前面盾牌形状的)
右面则是菜单,通过上下键选择条目,加减更改参数。
图中第一项为立体声开关,ADVsearch:自动搜台并保存到EEPROM里。
