一、蜂鳴器是干什么用的
蜂鳴器是一種(zhong)一體(ti)化(hua)的(de)(de)電(dian)子訊(xun)響器(qi)(qi),主(zhu)要是使(shi)用(yong)直流(liu)電(dian)壓(ya)進行供電(dian)。常見的(de)(de)功能(neng)就是將音(yin)頻信號(hao)轉化(hua)成為聲音(yin)信號(hao)的(de)(de)發(fa)音(yin)元器(qi)(qi)件。蜂(feng)鳴器(qi)(qi)具有體(ti)積(ji)小、重量輕、聲壓(ya)電(dian)平高、耗能(neng)少、壽命長以及使(shi)用(yong)方便等(deng)特點,因此(ci)被廣泛(fan)的(de)(de)使(shi)用(yong)在家(jia)用(yong)電(dian)器(qi)(qi)、銀行公安報(bao)警系(xi)統之中(zhong)等(deng)等(deng)。
二、蜂鳴器的作用和用途
蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)的主要作(zuo)用(yong)是提(ti)示或報警(jing),根據設(she)計和用(yong)途的不同,能發出音(yin)樂(le)聲、汽(qi)(qi)笛(di)聲、蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)聲、警(jing)報聲、電鈴(ling)聲等各種不同的聲音(yin)。蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi)廣泛應用(yong)于計算(suan)機(ji)行(xing)(xing)業(ye)(ye)(ye)(主板蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi),機(ji)箱蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi),電腦蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi))、打(da)印(yin)機(ji)(控制板蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi))、復印(yin)機(ji)、報警(jing)器(qi)(qi)(qi)行(xing)(xing)業(ye)(ye)(ye)(報警(jing)蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi),警(jing)報蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi))、電子(zi)玩具(音(yin)樂(le)蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi))、農業(ye)(ye)(ye)、汽(qi)(qi)車(che)(che)(che)電子(zi)設(she)備行(xing)(xing)業(ye)(ye)(ye)(車(che)(che)(che)載蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi),倒車(che)(che)(che)蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi),汽(qi)(qi)車(che)(che)(che)蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi),摩(mo)托車(che)(che)(che)蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi))、電話機(ji)(環(huan)保蜂(feng)(feng)(feng)(feng)鳴(ming)(ming)(ming)(ming)(ming)器(qi)(qi)(qi))、定(ding)時器(qi)(qi)(qi)、空(kong)調(diao)、醫療(liao)設(she)備等電聲行(xing)(xing)業(ye)(ye)(ye)、環(huan)境監控。
蜂(feng)鳴器(qi)(qi)在電子設(she)(she)備(bei)(bei)中有多種(zhong)(zhong)用途,最常見的是作(zuo)(zuo)為(wei)警報(bao)器(qi)(qi)或指示(shi)燈。例(li)如(ru),在家庭安防(fang)設(she)(she)備(bei)(bei)中,蜂(feng)鳴器(qi)(qi)被(bei)用作(zuo)(zuo)防(fang)盜警報(bao)器(qi)(qi),當(dang)門(men)窗(chuang)被(bei)非法破壞(huai)時將觸發(fa)警報(bao)聲音并發(fa)送消息給用戶。此外(wai),蜂(feng)鳴器(qi)(qi)還可以配(pei)合指示(shi)燈,向用戶傳遞各種(zhong)(zhong)設(she)(she)備(bei)(bei)狀態信息。
在工業自(zi)動化(hua)領域中,蜂鳴器也是一種常(chang)見的(de)輸出(chu)信(xin)號設(she)備。例(li)如,在流水線生產過程(cheng)中,當某個設(she)備出(chu)現故(gu)障時(shi),可(ke)以(yi)通過蜂鳴器提示工人(ren)及時(shi)維修。
除了作為警報器和指示器以外,蜂鳴器還(huan)有很多其他的應(ying)用。例(li)如(ru),在開車(che)時,倒(dao)車(che)雷達檢測到(dao)障(zhang)礙物時會發出蜂鳴聲提(ti)示(shi)駕駛員。在游(you)戲(xi)機、電視(shi)等娛樂(le)設備中,蜂鳴器也被用來傳遞(di)游(you)戲(xi)進程或者操作提(ti)示(shi)。
總之,蜂鳴器(qi)作為(wei)(wei)一種(zhong)基礎型、小(xiao)巧(qiao)、高效的聲響(xiang)器(qi)件,由于(yu)其廣(guang)泛的應用場(chang)景和低成本,已經成為(wei)(wei)了現代(dai)電子設備不可或缺的部分。
