超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)換能(neng)器(qi)是(shi)一(yi)種(zhong)將(jiang)電(dian)能(neng)轉(zhuan)換成機械(xie)能(neng)的(de)器(qi)件。其基本工作(zuo)原(yuan)理(li)(li)是(shi)將(jiang)聲(sheng)(sheng)(sheng)(sheng)源發出(chu)的(de)電(dian)信號通過轉(zhuan)換電(dian)路(lu)轉(zhuan)換為相應的(de)機械(xie)能(neng)量(liang)（如壓力、速(su)度(du)等(deng)(deng)）并作(zuo)用(yong)在(zai)負載上；當被測(ce)物(wu)體(ti)(ti)遇到(dao)(dao)該超(chao)聲(sheng)(sheng)(sheng)(sheng)振(zhen)(zhen)動時會產(chan)(chan)生(sheng)(sheng)反射(she)或透射(she)現象(xiang)。利用(yong)這(zhe)一(yi)原(yuan)理(li)(li)可(ke)以(yi)測(ce)量(liang)物(wu)體(ti)(ti)的(de)尺寸及結(jie)構形狀(zhuang)和位置精度(du)等(deng)(deng)多種(zhong)參數。目前(qian)常用(yong)的(de)超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)傳(chuan)感器(qi)有(you)壓阻式與變幅桿(gan)式兩種(zhong)類型。1.壓阻式超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)傳(chuan)感器(qi)的(de)特(te)點(dian)：具有(you)體(ti)(ti)積小、重量(liang)輕等(deng)(deng)優點(dian)。缺點(dian)是(shi)頻率低(di)(di)且(qie)易(yi)受(shou)溫度(du)影響(xiang)而(er)降低(di)(di)靈敏度(du)。2.變幅桿(gan)型超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)傳(chuan)感器(qi)的(de)工作(zuo)方式如下所示(shi)。首先把(ba)輸(shu)(shu)入(ru)電(dian)壓加(jia)到(dao)(dao)輸(shu)(shu)出(chu)端(duan)子上，使(shi)放大器(qi)工作(zuo)于放大狀(zhuang)態。由于振(zhen)(zhen)子受(shou)到(dao)(dao)激勵后產(chan)(chan)生(sheng)(sheng)的(de)位移(yi)量(liang)是(shi)變化(hua)的(de)，所以(yi)只要(yao)改變振(zhen)(zhen)子的(de)長度(du)即(ji)可(ke)調節輸(shu)(shu)出(chu)功率的(de)大小，從而(er)達到(dao)(dao)連續檢測(ce)的(de)目的(de)。在(zai)工業領域中，超(chao)聲(sheng)(sheng)(sheng)(sheng)波(bo)換能(neng)器(qi)可(ke)以(yi)用(yong)于清洗、切割、焊接等(deng)(deng)方面，具有(you)高效、節能(neng)、無污染等(deng)(deng)優點(dian)。

超(chao)聲(sheng)(sheng)波(bo)(bo)換(huan)能(neng)器(qi)在(zai)合適的(de)(de)(de)(de)電(dian)(dian)場(chang)激勵下能(neng)發生有(you)規律(lv)的(de)(de)(de)(de)振動，其(qi)振幅(fu)一般10μm左右(you)，這(zhe)(zhe)樣的(de)(de)(de)(de)振幅(fu)要(yao)(yao)直(zhi)接完成焊接和加工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)序是(shi)不夠(gou)的(de)(de)(de)(de)。連(lian)上(shang)通(tong)過合理設計的(de)(de)(de)(de)變(bian)幅(fu)桿后，超(chao)聲(sheng)(sheng)波(bo)(bo)的(de)(de)(de)(de)振幅(fu)可以在(zai)很大的(de)(de)(de)(de)范圍內變(bian)化，只要(yao)(yao)材料(liao)強度足夠(gou)，振幅(fu)可以超(chao)過100μm。    因加工(gong)(gong)(gong)(gong)(gong)方(fang)式(shi)和要(yao)(yao)求不同(tong)，換(huan)能(neng)器(qi)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)方(fang)式(shi)大致(zhi)可分為(wei)連(lian)續(xu)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)（如花邊機(ji)，CD機(ji)，清洗(xi)機(ji)，拉(la)鏈機(ji)）和脈沖(chong)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)（如塑料(liao)焊機(ji)），不同(tong)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)方(fang)式(shi)對換(huan)能(neng)器(qi)的(de)(de)(de)(de)要(yao)(yao)求是(shi)不同(tong)的(de)(de)(de)(de)。    一般而言(yan)，連(lian)續(xu)式(shi)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)幾(ji)乎沒有(you)停頓(dun)時(shi)間(jian)，但工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)電(dian)(dian)流不是(shi)很大，脈沖(chong)工(gong)(gong)(gong)(gong)(gong)作(zuo)(zuo)是(shi)間(jian)歇的(de)(de)(de)(de)，有(you)停頓(dun)，但瞬間(jian)電(dian)(dian)流很大。平均而言(yan)，二種狀(zhuang)態的(de)(de)(de)(de)功率(lv)都是(shi)很大的(de)(de)(de)(de)。    超(chao)聲(sheng)(sheng)波(bo)(bo)換(huan)能(neng)器(qi)也(ye)可以使用(yong)非壓(ya)電(dian)(dian)原理。例(li)如：磁致(zhi)伸縮。具有(you)這(zhe)(zhe)種性質(zhi)的(de)(de)(de)(de)材料(liao)暴露于磁場(chang)時(shi)會產(chan)生微小形變(bian)，可制成實(shi)用(yong)的(de)(de)(de)(de)換(huan)能(neng)器(qi)。由于超(chao)聲(sheng)(sheng)波(bo)(bo)具有(you)頻(pin)率(lv)高、能(neng)量(liang)大、穿(chuan)透力強等特點，因此在(zai)某些特殊場(chang)合下更加適用(yong)。廣東口罩超(chao)聲(sheng)(sheng)波(bo)(bo)換(huan)能(neng)器(qi)廠家價格
