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)。 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。上海生产AD16系列蜂鸣器哪家强
