1、 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 1520 米，将发射器主体安装在大门里，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
