一、蜂鳴器是干什么用的

蜂鳴器是一種一體(ti)化(hua)的電(dian)子訊響器，主要是使用(yong)直流電(dian)壓(ya)進行(xing)供(gong)電(dian)。常見的功能就是將音(yin)頻信(xin)號轉(zhuan)化(hua)成(cheng)為聲(sheng)音(yin)信(xin)號的發音(yin)元器件(jian)。蜂鳴器具有體(ti)積小(xiao)、重量輕、聲(sheng)壓(ya)電(dian)平高(gao)、耗能少(shao)、壽命長以及使用(yong)方(fang)便等(deng)特點，因(yin)此被廣(guang)泛(fan)的使用(yong)在家用(yong)電(dian)器、銀行(xing)公安報警系(xi)統之中等(deng)等(deng)。

二、蜂鳴器的作用和用途

蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)的(de)主要作用(yong)是提示或報(bao)(bao)警，根據設計和用(yong)途的(de)不(bu)同(tong)，能(neng)發出音樂(le)聲(sheng)、汽笛聲(sheng)、蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)聲(sheng)、警報(bao)(bao)聲(sheng)、電(dian)(dian)鈴聲(sheng)等各種不(bu)同(tong)的(de)聲(sheng)音。蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)廣泛應用(yong)于計算(suan)機(ji)行(xing)業(ye)（主板蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，機(ji)箱蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，電(dian)(dian)腦蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、打印(yin)機(ji)（控(kong)制板蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、復印(yin)機(ji)、報(bao)(bao)警器(qi)(qi)(qi)(qi)行(xing)業(ye)（報(bao)(bao)警蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，警報(bao)(bao)蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、電(dian)(dian)子玩具（音樂(le)蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、農業(ye)、汽車(che)(che)電(dian)(dian)子設備行(xing)業(ye)（車(che)(che)載蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，倒(dao)車(che)(che)蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，汽車(che)(che)蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，摩托車(che)(che)蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、電(dian)(dian)話機(ji)（環保蜂(feng)(feng)(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、定時器(qi)(qi)(qi)(qi)、空調、醫(yi)療設備等電(dian)(dian)聲(sheng)行(xing)業(ye)、環境(jing)監(jian)控(kong)。

蜂(feng)(feng)鳴器(qi)在電子設備(bei)中有多種(zhong)(zhong)用(yong)(yong)途，最常見的是作(zuo)(zuo)為警報(bao)器(qi)或指示燈。例(li)如，在家庭安防設備(bei)中，蜂(feng)(feng)鳴器(qi)被用(yong)(yong)作(zuo)(zuo)防盜警報(bao)器(qi)，當門窗被非(fei)法(fa)破壞時將觸發警報(bao)聲音并發送消息(xi)給用(yong)(yong)戶(hu)。此外，蜂(feng)(feng)鳴器(qi)還可以配合指示燈，向用(yong)(yong)戶(hu)傳遞各種(zhong)(zhong)設備(bei)狀態信息(xi)。

在(zai)工業(ye)自動(dong)化領域中，蜂鳴(ming)器也是(shi)一種常見的輸出信號設備(bei)。例如，在(zai)流水線生產過(guo)程中，當(dang)某個(ge)設備(bei)出現(xian)故障時(shi)，可(ke)以通過(guo)蜂鳴(ming)器提示工人及時(shi)維修。

除了作為警報器和指示器以外，蜂鳴器還有(you)很多其他的(de)應用。例如(ru)，在(zai)開車時，倒車雷達檢測到障礙物時會發出蜂(feng)鳴聲提示駕駛員(yuan)。在(zai)游戲機、電視等娛樂設備中，蜂(feng)鳴器也被用來傳遞(di)游戲進程或者操作提示。

總之，蜂鳴器作(zuo)為一種基(ji)礎型、小巧、高效的聲響器件，由于其廣泛(fan)的應用場景和低成(cheng)本，已經成(cheng)為了現代電(dian)子設備不可或(huo)缺的部(bu)分。
