      蜂鸣器制作工艺：(1)制蜂鸣器备电磁铁M:在长约6厘米的铁螺栓上绕100圈导线,线端留下5厘米作引线,用透明胶布把线圈粘好,以免线圈松开,再用胶布把它粘在一个盒子上,电磁铁就做好了。(2)制备弹片P:从铁罐头盒上剪下一条宽约2厘米的长铁片，弯成直角，把电磁铁的一条引线接在弹片上，再用胶布把弹片紧贴在木板上。(3)用曲别针做触头Q，用书把曲别针垫高，用胶布粘牢，引出一条导线，如图连接好电路。(4)调节M与P之间的距离(通过移动盒子)，使电磁铁能吸引弹片，调节触点与弹片之间的距离，使它们能恰好接触，通电后就可以听到蜂鸣声。折叠编辑本段分类静安区西门子AD16系列蜂鸣器厂家直销如果给预直流信号蜂鸣器是不响应的，因为磁路恒定，钼片不能振动发音。
