      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

       蜂鸣器：外形：无源蜂鸣器（外壳有“+”号，背面为绿色电路板）有源蜂鸣器（无电路板而用黑胶封闭）源为电源，或者振荡电路内部结构及驱动发声方式：电磁式蜂鸣器：由振荡器、电磁线圈、磁铁、震动膜片、外壳等组成接通电源后，振荡器产生的音频信号电流通过电磁线圈，使电磁线圈产生磁场，振动膜片在在电磁线圈和磁铁的相互作用下，周期性振动发声。属于有源蜂鸣器压电式蜂鸣：由多谐振荡器、压电蜂鸣器片、阻抗匹配器及共鸣箱、外壳等组成多谐振荡器由晶体管或集成电路构成，当接通电源后（），多谐振荡器起振，输出的音频信号，阻抗匹配器推动压电蜂鸣器发声。属于无源蜂鸣器用途：提示或报警自激蜂鸣器是直流电压进行驱动的，不需要利用交流信号进行驱动，只需对驱动口输出驱动电平并通过放大电路（使用单极管放大，单片机起控制作用）放大驱动电流就能使蜂鸣器发出声音。开发板上蜂鸣器为自激蜂鸣器，通常都使用采用直流电压进行驱动的蜂鸣器。2、改变单片机引脚输出波形的频率（即输入蜂鸣器的波形频率，即波形周期），就可以调整蜂鸣器音调产生各种不同音色、音调的声音。改变输出电平的高低电平占空比，则可以控制蜂鸣器声音的大小（高电平所占时间短，声音低）。 压电蜂鸣片由锆钛酸铅或铌镁酸铅压电陶瓷材料制成。接触器AD16系列蜂鸣器性价比
