一、蜂鳴器是干什么用的
蜂鳴器是(shi)一種一體化的電(dian)子訊響器(qi),主要是(shi)使(shi)用(yong)直流電(dian)壓(ya)進行供電(dian)。常見的功能(neng)就是(shi)將音(yin)(yin)頻信(xin)號轉化成為聲音(yin)(yin)信(xin)號的發音(yin)(yin)元(yuan)器(qi)件。蜂鳴器(qi)具有體積(ji)小、重(zhong)量輕、聲壓(ya)電(dian)平高(gao)、耗能(neng)少、壽命長以(yi)及使(shi)用(yong)方便等(deng)(deng)特點,因此被廣泛(fan)的使(shi)用(yong)在家用(yong)電(dian)器(qi)、銀行公安(an)報警系統之中等(deng)(deng)等(deng)(deng)。
二、蜂鳴器的作用和用途
蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)的主要作用是(shi)提(ti)示或(huo)報(bao)警(jing),根據設(she)計(ji)和用途的不同(tong)(tong),能發出音樂聲(sheng)、汽(qi)笛聲(sheng)、蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)聲(sheng)、警(jing)報(bao)聲(sheng)、電鈴聲(sheng)等(deng)各種不同(tong)(tong)的聲(sheng)音。蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi)廣泛應用于計(ji)算機(ji)行業(ye)(主板(ban)蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi),機(ji)箱蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi),電腦蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi))、打印(yin)機(ji)(控(kong)制板(ban)蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi))、復印(yin)機(ji)、報(bao)警(jing)器(qi)(qi)(qi)(qi)行業(ye)(報(bao)警(jing)蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi),警(jing)報(bao)蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi))、電子(zi)玩(wan)具(音樂蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi))、農(nong)業(ye)、汽(qi)車(che)(che)電子(zi)設(she)備行業(ye)(車(che)(che)載(zai)蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi),倒車(che)(che)蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi),汽(qi)車(che)(che)蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi),摩托(tuo)車(che)(che)蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi))、電話機(ji)(環保(bao)蜂(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)(qi))、定時(shi)器(qi)(qi)(qi)(qi)、空調、醫(yi)療設(she)備等(deng)電聲(sheng)行業(ye)、環境監(jian)控(kong)。
蜂(feng)(feng)鳴器(qi)(qi)在電子設備中(zhong)有(you)多種(zhong)用(yong)途,最(zui)常見(jian)的是作(zuo)為警報(bao)器(qi)(qi)或指(zhi)示燈(deng)。例如,在家庭安防(fang)設備中(zhong),蜂(feng)(feng)鳴器(qi)(qi)被(bei)用(yong)作(zuo)防(fang)盜警報(bao)器(qi)(qi),當門(men)窗被(bei)非法破壞時將觸發(fa)警報(bao)聲音并發(fa)送(song)消息給用(yong)戶。此外,蜂(feng)(feng)鳴器(qi)(qi)還可以(yi)配合指(zhi)示燈(deng),向用(yong)戶傳遞各(ge)種(zhong)設備狀態信息。
在工業(ye)自動化領(ling)域中(zhong),蜂鳴(ming)(ming)器也是一種常(chang)見的輸(shu)出信號設備。例如,在流水線生產過(guo)程(cheng)中(zhong),當某個設備出現(xian)故障時,可(ke)以通過(guo)蜂鳴(ming)(ming)器提示工人及時維修(xiu)。
除了作為警報器和指示器以外,蜂鳴器還有很多其他的(de)應用。例如,在開車時(shi),倒車雷達檢測到障礙(ai)物時(shi)會發出蜂(feng)鳴聲提示(shi)駕駛(shi)員。在游戲機(ji)、電視等娛樂設(she)備中,蜂(feng)鳴器(qi)也被(bei)用來傳(chuan)遞游戲進程或(huo)者(zhe)操作提示(shi)。
總之(zhi),蜂鳴器作為一種基礎型(xing)、小巧(qiao)、高效的(de)聲(sheng)響(xiang)器件,由于其廣泛的(de)應用場景(jing)和低(di)成(cheng)本,已經(jing)成(cheng)為了現代電子(zi)設備不可或缺的(de)部(bu)分(fen)。
