Abstract

一种触发式自行车电子铃、由电源、电源开关、集 成电路芯片、扬声器组成,所有零件都安置在一个壳 体内,组成一个整体式电子铃,便于安装。该铃只要 用手轻轻触摸铃盖,即可发声,且所发声音信号类型 可以通过选用集成电路芯片而定,可以是简单的乐曲 或蜂鸣声等。本电子铃由于没有采用金属转动件,所 以不会因受潮生锈而影响使用。

Description

本实用新型涉及自行车铃,自行车电子铃。
自行车常用的金属铃会因下雨后受潮生锈等使用不便,打不响。
本实用新型的目的是研制用电子发声器发出声音信号代替金属铃信号,使自行车铃免受下雨潮湿的影响而不能使用。
本实用新型的内容是将电源、电源开关、集成电路芯片、扬声器等元件安置在一个壳体内,组成一个整体式的电子铃。由于采用了电子发声器,所以可避免金属铃因雨水受潮等原因造成生锈不能发声等缺陷。
说明附图如下:
图1为本实用新型触发式自行车电子铃的结构剖视图。
图2为本实用新型电路原理图。
结合附图说明实施例如下:
整个铃的壳件由壳盖(4)及壳底(7)组成,电源(8),扬声器(6),集成电路芯片(5)都安置在底座(10)上,底座(10)安置在壳体内,底座(10)与壳盖(4)有弹簧(2)相连,在壳盖(4)的内面设置一    圆形铜片(1),在底座(10)与(1)相对应的位置设置另一圆形铜片(3),铜片(1)和(3)作为整个电路的电源开关触点。壳盖(4)及壳底(7)可用镙钉连接,(9)为电源盒盖,壳底(7)上有扬声小孔,底座(10)有一伸出端用来在车身上固定电子铃。
图2为电路原理图,其中5为集成电路芯片,6为扬声器。
本实用新型的电子铃在使用时,只要用手轻轻触摸壳盖(4),铜片(1)、(3)即接通电路,扬声器即发声,发生的声信号种类可以采用各种芯片任意选定,可以是简单的乐曲,蜂呜声或其他声音信号。由于本电子铃中没有金属转动件,所以不怕受潮生锈等影响使用。
