1、安徽财贸职业学院毕业设计无线遥控音乐门铃摘要门铃，在中国古代就有，它是有钱人家的象征；在国外，同样也是贵族身份的代表。但是今天，门铃早已普及到平民百姓家中。随着人们生活水平的提高和居住环境的改善，人们对住宅小区智能型的要求也日益迫切。不管是在城市还是农村，现在的人们也越来越喜欢居住大房子，但因居住房间离大门口较远，来人敲门不容易听到，不仅尴尬，更重要的是经常耽误事。传统的有线门铃，一是布线较长成本高，后期维护麻烦，二是碍手碍脚，非常的不方便。无线门铃工作相对比较稳定，不易受外界干扰，作用距离可达15～20米，将发射器主体安装

2、在大门里，而按钮用细导线引到外面并固定牢靠，接收器既可悬挂在屋内墙上，也可随意摆放在中厅或卧室，当来访者按下发射器按钮时，就会响起宏亮悦耳的"叮咚"声，通知有客到来，给家人的生活带来了极大方便。我们此次设计的无线遥控音乐门铃能隔墙遥控，遥控距离远，不要架线，节省布线材料。此电路采用的是TQ33G系列三种声音可选择的音乐芯片，分别是双音叮咚，西敏寺，爱丽斯。是利用无线电磁波的发射和接受来实现功能的。关键词：无线遥控音乐门铃TC4069UBP振荡-2-安徽财贸职业学院毕业设计Topic:Wirelessremotecontrol
