一、蜂鳴器是干什么用的

蜂鳴器是一種一體化的(de)電子(zi)訊(xun)響(xiang)器，主要是使(shi)用直(zhi)流電壓進行供電。常見(jian)的(de)功能(neng)就(jiu)是將音頻信號轉化成為聲音信號的(de)發(fa)音元器件。蜂鳴器具有(you)體積小、重量(liang)輕、聲壓電平(ping)高、耗能(neng)少、壽命長以及(ji)使(shi)用方(fang)便等特點，因此(ci)被廣泛的(de)使(shi)用在家用電器、銀行公(gong)安報(bao)警系(xi)統之(zhi)中等等。

二、蜂鳴器的作用和用途

蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)的(de)(de)主要作用(yong)(yong)(yong)是提(ti)示或報警(jing)，根(gen)據設計和用(yong)(yong)(yong)途(tu)的(de)(de)不同，能發出音(yin)樂聲(sheng)、汽笛聲(sheng)、蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)聲(sheng)、警(jing)報聲(sheng)、電(dian)(dian)鈴聲(sheng)等各種不同的(de)(de)聲(sheng)音(yin)。蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)廣泛應用(yong)(yong)(yong)于計算機(ji)行業（主板蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，機(ji)箱蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，電(dian)(dian)腦蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、打印(yin)機(ji)（控制板蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、復(fu)印(yin)機(ji)、報警(jing)器(qi)(qi)(qi)(qi)行業（報警(jing)蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，警(jing)報蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、電(dian)(dian)子玩具(ju)（音(yin)樂蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、農業、汽車電(dian)(dian)子設備行業（車載蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，倒車蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，汽車蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)，摩托(tuo)車蜂(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)鳴(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)）、定時(shi)器(qi)(qi)(qi)(qi)、空調、醫療設備等電(dian)(dian)聲(sheng)行業、環境監控。

蜂(feng)鳴(ming)器在電子設備中有(you)多種用(yong)(yong)(yong)途(tu)，最常見的是作為警(jing)報器或(huo)指(zhi)示(shi)燈。例如，在家庭安防(fang)設備中，蜂(feng)鳴(ming)器被用(yong)(yong)(yong)作防(fang)盜警(jing)報器，當門(men)窗被非法破壞(huai)時將觸發警(jing)報聲音并發送(song)消息(xi)給(gei)用(yong)(yong)(yong)戶(hu)。此外(wai)，蜂(feng)鳴(ming)器還可以配合指(zhi)示(shi)燈，向(xiang)用(yong)(yong)(yong)戶(hu)傳遞各種設備狀態信(xin)息(xi)。

在工(gong)(gong)業自動化領域中，蜂鳴器(qi)也是一種常見的輸出(chu)信號設備。例(li)如，在流水線生產過程中，當(dang)某個(ge)設備出(chu)現故障時，可以通過蜂鳴器(qi)提示工(gong)(gong)人及時維修。

除了作為警報器和指示器以外，蜂鳴器還有很多其他的應用。例如，在(zai)(zai)開車(che)時，倒(dao)車(che)雷達檢測(ce)到障礙物(wu)時會發出蜂鳴(ming)聲(sheng)提示駕(jia)駛(shi)員。在(zai)(zai)游戲機、電視(shi)等(deng)娛樂設(she)備中，蜂鳴(ming)器也(ye)被用來(lai)傳遞游戲進程或者操作提示。

總之，蜂鳴(ming)器(qi)作為(wei)一種基礎型、小(xiao)巧、高效的(de)聲(sheng)響(xiang)器(qi)件，由(you)于(yu)其廣泛的(de)應用場景和低成(cheng)本，已經成(cheng)為(wei)了現代電子(zi)設(she)備不(bu)可或(huo)缺(que)的(de)部(bu)分。
