　　要了(le)解電(dian)子(zi)振(zhen)蕩(dang)器的工作原理，考察真實(shi)**中的實(shi)例(li)會很(hen)有幫助。在本文中，我們將帶您了(le)解振(zhen)蕩(dang)器背后的基本概念以及它們在電(dian)子(zi)設備(bei)中的用法。
　　振蕩(dang)器基礎知識
　　***常見(jian)的振(zhen)蕩器之***就是時鐘的鐘擺(bai)。如果您推(tui)動鐘擺(bai)開始擺(bai)動，它(ta)將以某種頻率(lv)振(zhen)蕩——每秒鐘會來回(hui)擺(bai)動***定的次數(shu)。控(kong)制頻率(lv)的主要是鐘擺(bai)的長度。
　　要(yao)使(shi)物體(ti)振(zhen)蕩，能(neng)(neng)(neng)量(liang)必須在(zai)(zai)兩(liang)種(zhong)(zhong)形態(tai)(tai)之間(jian)來(lai)回(hui)轉換(huan)(huan)。例(li)如，在(zai)(zai)鐘(zhong)擺(bai)中(zhong)，能(neng)(neng)(neng)量(liang)在(zai)(zai)勢(shi)(shi)(shi)能(neng)(neng)(neng)和動(dong)能(neng)(neng)(neng)之間(jian)轉換(huan)(huan)。當鐘(zhong)擺(bai)位于(yu)擺(bai)動(dong)的(de)***端(duan)，其(qi)能(neng)(neng)(neng)量(liang)全部是(shi)勢(shi)(shi)(shi)能(neng)(neng)(neng)，并準(zhun)備落下。當鐘(zhong)擺(bai)在(zai)(zai)循(xun)環的(de)中(zhong)間(jian)，所有(you)勢(shi)(shi)(shi)能(neng)(neng)(neng)轉換(huan)(huan)為動(dong)能(neng)(neng)(neng)，鐘(zhong)擺(bai)以***快的(de)速度移動(dong)。當鐘(zhong)擺(bai)向另***側(ce)運動(dong)時，所有(you)動(dong)能(neng)(neng)(neng)又轉為勢(shi)(shi)(shi)能(neng)(neng)(neng)。這兩(liang)種(zhong)(zhong)形態(tai)(tai)間(jian)的(de)能(neng)(neng)(neng)量(liang)的(de)轉換(huan)(huan)就是(shi)導(dao)致振(zhen)蕩的(de)原因(yin)。
　　***后由于摩擦(ca)的作用，任何物理振蕩都(dou)會停止。要(yao)繼續運動(dong)，必須(xu)在(zai)(zai)每次(ci)循環中添加(jia)少許(xu)能(neng)量(liang)。在(zai)(zai)擺鐘(zhong)里(li)，保持鐘(zhong)擺移動(dong)的能(neng)量(liang)來自彈簧。鐘(zhong)擺在(zai)(zai)每次(ci)敲鐘(zhong)時都(dou)得到***點(dian)推力，以彌補因摩擦(ca)而失去的能(neng)量(liang)。電子振蕩器(qi)
　　振(zhen)蕩器(qi)要正常工作，能量(liang)必須在兩種形態(tai)之間來回轉換(huan)。
　　所(suo)謂電(dian)容(rong)器就是能夠(gou)儲存電(dian)荷的(de)“容(rong)器"。只(zhi)不過這種“容(rong)器"是***種特殊的(de)物質(zhi)——電(dian)荷，而(er)且其所(suo)存儲的(de)正負電(dian)荷等量地分(fen)布于兩塊不直(zhi)接導(dao)通(tong)的(de)導(dao)體(ti)(ti)板(ban)(ban)上。至此，我們就可以描述電(dian)容(rong)器的(de)基本結構：兩塊導(dao)體(ti)(ti)板(ban)(ban)(通(tong)常為(wei)金屬板(ban)(ban))中間隔以電(dian)介質(zhi)，即構成(cheng)電(dian)容(rong)器的(de)基本模型(xing)和(he)電(dian)感器
　　電(dian)(dian)(dian)感(gan)(gan)器(qi)(qi)(qi)(qi)是能夠把電(dian)(dian)(dian)能轉(zhuan)化為(wei)磁能而(er)存儲起來的(de)(de)元件。電(dian)(dian)(dian)感(gan)(gan)器(qi)(qi)(qi)(qi)的(de)(de)結構(gou)類(lei)似于變壓器(qi)(qi)(qi)(qi)，但只有(you)***個繞(rao)組。電(dian)(dian)(dian)感(gan)(gan)器(qi)(qi)(qi)(qi)具有(you)***定的(de)(de)電(dian)(dian)(dian)感(gan)(gan)，它(ta)(ta)只阻止電(dian)(dian)(dian)流(liu)的(de)(de)變化。如果(guo)(guo)電(dian)(dian)(dian)感(gan)(gan)器(qi)(qi)(qi)(qi)中沒有(you)電(dian)(dian)(dian)流(liu)通過，則(ze)它(ta)(ta)阻止電(dian)(dian)(dian)流(liu)流(liu)過它(ta)(ta);如果(guo)(guo)有(you)電(dian)(dian)(dian)流(liu)流(liu)過它(ta)(ta)，則(ze)電(dian)(dian)(dian)路斷開(kai)時它(ta)(ta)將試圖(tu)維持電(dian)(dian)(dian)流(liu)不變。電(dian)(dian)(dian)感(gan)(gan)器(qi)(qi)(qi)(qi)又(you)稱(cheng)扼流(liu)器(qi)(qi)(qi)(qi)、電(dian)(dian)(dian)抗(kang)器(qi)(qi)(qi)(qi)、動態電(dian)(dian)(dian)抗(kang)器(qi)(qi)(qi)(qi)。連接在***起，即可制成***個非常簡單的(de)(de)振蕩器(qi)(qi)(qi)(qi)。如果(guo)(guo)您閱(yue)讀過電(dian)(dian)(dian)容(rong)器(qi)(qi)(qi)(qi)工作(zuo)原理(li)和電(dian)(dian)(dian)感(gan)(gan)
　　能(neng)(neng)產(chan)生電(dian)(dian)(dian)(dian)感(gan)(gan)作(zuo)(zuo)用(yong)的元(yuan)件統(tong)稱為(wei)電(dian)(dian)(dian)(dian)感(gan)(gan)原件，常(chang)常(chang)直接簡稱為(wei)電(dian)(dian)(dian)(dian)感(gan)(gan)。電(dian)(dian)(dian)(dian)感(gan)(gan)器(qi)在電(dian)(dian)(dian)(dian)子制作(zuo)(zuo)中雖然使用(yong)得不是很多(duo)，但它們在電(dian)(dian)(dian)(dian)路中同樣(yang)重要。我們認為(wei)電(dian)(dian)(dian)(dian)感(gan)(gan)器(qi)和(he)電(dian)(dian)(dian)(dian)容(rong)器(qi)***樣(yang)，也是***種儲能(neng)(neng)元(yuan)件，它能(neng)(neng)把電(dian)(dian)(dian)(dian)能(neng)(neng)轉變為(wei)磁場能(neng)(neng)，并在磁場中儲存(cun)能(neng)(neng)量。
　　器(qi)(qi)工作原(yuan)理，就會知道電(dian)(dian)(dian)容(rong)器(qi)(qi)和電(dian)(dian)(dian)感器(qi)(qi)都(dou)能(neng)儲存能(neng)量(liang)。電(dian)(dian)(dian)容(rong)器(qi)(qi)以(yi)靜電(dian)(dian)(dian)場的形(xing)式儲存能(neng)量(liang)，而電(dian)(dian)(dian)感器(qi)(qi)則使用磁場
　　電流(liu)、運(yun)動電荷、磁體(ti)或變化(hua)電場(chang)(chang)周圍空(kong)間存(cun)在的(de)(de)***種(zhong)特殊形態的(de)(de)物質。由于磁體(ti)的(de)(de)磁性來源于電流(liu)，電流(liu)是電荷的(de)(de)運(yun)動，因而概括地(di)說，磁場(chang)(chang)是由運(yun)動電荷或變化(hua)電場(chang)(chang)產生(sheng)的(de)(de)。磁場(chang)(chang)的(de)(de)基本特征(zheng)是能對其中的(de)(de)運(yun)動電荷施加作用(yong)力(li)(li)，磁場(chang)(chang)對電流(liu)、對磁體(ti)的(de)(de)作用(yong)力(li)(li)或力(li)(li)矩皆源于此。。
　　如果(guo)用電池
　　電(dian)(dian)(dian)池(chi)(chi)是***種能(neng)量轉(zhuan)(zhuan)化(hua)(hua)與(yu)儲存的裝置，它通過(guo)反映將化(hua)(hua)學(xue)能(neng)或者物理能(neng)轉(zhuan)(zhuan)化(hua)(hua)為電(dian)(dian)(dian)能(neng)。電(dian)(dian)(dian)池(chi)(chi)即***種化(hua)(hua)學(xue)電(dian)(dian)(dian)源，它由兩種不同成分(fen)的電(dian)(dian)(dian)化(hua)(hua)學(xue)活性電(dian)(dian)(dian)***分(fen)別組成正負兩***浸泡(pao)再能(neng)提(ti)供媒體傳導作用(yong)的電(dian)(dian)(dian)解質中，當連接在某***外部載體上時，通過(guo)轉(zhuan)(zhuan)換其內部的化(hua)(hua)學(xue)能(neng)來提(ti)供電(dian)(dian)(dian)能(neng)。
　　為電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)(qi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，然(ran)后將(jiang)(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)感器(qi)(qi)(qi)插入電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)，將(jiang)(jiang)會(hui)發(fa)生以下情況： 電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)(qi)將(jiang)(jiang)通(tong)(tong)過電(dian)(dian)(dian)(dian)(dian)(dian)感器(qi)(qi)(qi)開(kai)始(shi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)。同時電(dian)(dian)(dian)(dian)(dian)(dian)感器(qi)(qi)(qi)將(jiang)(jiang)建立磁(ci)場。 ***旦電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)(qi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)完畢(bi)，電(dian)(dian)(dian)(dian)(dian)(dian)感器(qi)(qi)(qi)將(jiang)(jiang)嘗試保持電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中的(de)電(dian)(dian)(dian)(dian)(dian)(dian)流，為電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)(qi)的(de)另(ling)***個(ge)板充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。 當電(dian)(dian)(dian)(dian)(dian)(dian)感器(qi)(qi)(qi)的(de)磁(ci)場消失(shi)后，電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)(qi)已(yi)再次充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(但充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)***性相反)，將(jiang)(jiang)再次通(tong)(tong)過電(dian)(dian)(dian)(dian)(dian)(dian)感器(qi)(qi)(qi)放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)。
　　這種振(zhen)蕩(dang)將持續(xu)，直到金屬線中的(de)(de)電(dian)阻耗完能(neng)量為(wei)止。該振(zhen)蕩(dang)頻(pin)率取決于(yu)電(dian)感器(qi)(qi)和電(dian)容(rong)器(qi)(qi)的(de)(de)大小(xiao)。諧振(zhen)電(dian)路在(zai)簡單的(de)(de)晶體收音機中，***個由電(dian)容(rong)器(qi)(qi)或電(dian)感器(qi)(qi)組成的(de)(de)振(zhen)蕩(dang)器(qi)(qi)充當(dang)收音機的(de)(de)調諧器(qi)(qi)
　　某些車(che)載主(zhu)機所具有(you)(you)的FM/AM調(diao)(diao)諧(xie)器或TV調(diao)(diao)諧(xie)器，具有(you)(you)這些調(diao)(diao)諧(xie)器的車(che)載主(zhu)機也就具有(you)(you)了FM/AM收音(yin)或電(dian)視(shi)接收功能。目(mu)前***般車(che)載主(zhu)機的調(diao)(diao)諧(xie)器都(dou)是指(zhi)收音(yin)機FM/AM調(diao)(diao)諧(xie)器。FM和AM都(dou)是信號調(diao)(diao)制(zhi)方式，FM是指(zhi)調(diao)(diao)頻，AM是指(zhi)調(diao)(diao)幅。。
