    結(jié)構(gòu)原理蜂鳴器1.壓電式蜂鳴器壓電式蜂鳴器主要由多諧振蕩器、壓電蜂鳴片、阻抗匹配器及共鳴箱、外殼等組成。有的壓電式蜂鳴器外殼上還裝有發(fā)光二極管。多諧振蕩器由晶體管或集成電路構(gòu)成。當(dāng)接通電源后(),多諧振蕩器起振,輸出，阻抗匹配器推動壓電蜂鳴片發(fā)聲。蜂鳴器壓電蜂鳴片由鋯鈦酸鉛或鈮鎂酸鉛壓電陶瓷材料制成。在陶瓷片的兩面鍍上銀電極，經(jīng)極化和老化處理后，再與黃銅片或不銹鋼片粘在一起。2.電磁式蜂鳴器電磁式蜂鳴器由振蕩器、電磁線圈、磁鐵、振動膜片及外殼等組成。接通電源后，振蕩器產(chǎn)生的音頻信號電流通過電磁線圈，使電磁線圈產(chǎn)生磁場。振動膜片在電磁線圈和磁鐵的相互作用下，周期性地振動發(fā)聲。 閔行區(qū)控制箱AD16系列蜂鳴器代理品牌用曲別針做觸頭Ｑ，用書把曲別針墊高，用膠布粘牢，引出一條導(dǎo)線，如圖連接好電路。

    直流電源通過電磁線圈，再由輸出端通過二極管給集成電路驅(qū)動芯片供電，內(nèi)部振蕩電路工作，并輸出一定頻率信號經(jīng)輸出端驅(qū)動單組電磁線圈，使得蜂鳴器發(fā)出聲音，聲音的頻率由集成電路驅(qū)動芯片內(nèi)部振蕩器的頻率而定。本發(fā)明，由于集成電路驅(qū)動芯片的電源連接電容，所以所述集成電路驅(qū)動芯片不容易被損壞，并且不會對系統(tǒng)造成比較大的沖擊。綜上所述，本發(fā)明帶來的有益效果：一種高可靠性內(nèi)置集成電路驅(qū)動芯片的蜂鳴器，具有可靠性高和成本低的優(yōu)點(diǎn)。附圖說明圖1是本發(fā)明的結(jié)構(gòu)示意圖。圖2是本發(fā)明的電路示意圖。具體實(shí)施方式為使本發(fā)明的目的、技術(shù)方案和優(yōu)點(diǎn)更加清楚，以下結(jié)合附圖及具體實(shí)施例，對本發(fā)明作進(jìn)一步地詳細(xì)說明。如圖1所示，本發(fā)明提供一種高可靠性內(nèi)置集成電路驅(qū)動芯片的蜂鳴器，包括集成電路驅(qū)動芯片10、電容11、單組電磁線圈5、線路板6、支架3、磁環(huán)4、振動片2、正極針腳8、負(fù)極針腳9、殼體1、密封膠7。在實(shí)際安裝中如圖1所示，其中所述集成電路驅(qū)動芯片10、電容11、正極針腳8、負(fù)極針腳9焊接在線路板6上。如圖2，結(jié)合圖1，線路連接關(guān)系為：集成電路驅(qū)動芯片10電源連接電容11的一端，電容11的另一端連接負(fù)極針腳9，集成電路驅(qū)動芯片10地線端連接負(fù)極針腳9。
