18、路功率放大 電路，使之能夠成為電腦和MP3使用的多媒體有源小音箱。三、 課程設(shè)計(jì)的題目要求： 使用TDA2822集成電路設(shè)計(jì)一個(gè)立體聲音頻功率放大器。查閱TDA2822集成電路資料，根據(jù)資料進(jìn)行設(shè)計(jì)，確定輸出功率、電源電壓、外圍電路元器件的參數(shù)等讓它成為電腦和MP3的多媒體有源小音箱。四、 課程設(shè)計(jì)實(shí)驗(yàn)內(nèi)容：1、實(shí)現(xiàn)意義： TDA2822M功率放大器是電子系統(tǒng)中不可缺少的設(shè)備之一，也是模擬電路理論知識(shí)的根本內(nèi)容之一。完成一個(gè)功率放大器的設(shè)計(jì)，并進(jìn)行安裝調(diào)試，既可以到達(dá)對(duì)模擬電路理論知識(shí)的較全面的運(yùn)用，也能掌握模擬電路的實(shí)際安裝調(diào)試技術(shù)，具有很好的使用價(jià)值。通過學(xué)習(xí)使用TDA2822M集成電路在

19、以后的生活中就可以應(yīng)用此類實(shí)驗(yàn)實(shí)現(xiàn)電腦和MP3的多媒體有源小音箱的使用；有時(shí)如果你的電腦小音箱壞了或MP3的小喇叭了，還可以自己修呢。知識(shí)伴隨生活中的一點(diǎn)一滴。2、實(shí)現(xiàn)方法：為了得到需要的輸出功率，電路須選集電極電機(jī)功率足夠大的三極管，功放管的工作電流和集電極電壓也較高。電路設(shè)計(jì)使用中首先要考慮怎樣充分地發(fā)揮三極管功能而又不損壞三極管。由于電路中功放管工作狀態(tài)常接近極限值，所以攻放電流的調(diào)整和使用要小心，不宜超限使用。3、電路組成： TDA2822M的內(nèi)部結(jié)構(gòu)圖4、電路原理分析：如圖表2所示：TDA2822M必須把電壓降到8V以下，電壓最低可達(dá)1.8V，R1、R2一般選用10k的碳膜電阻，C1

20、、C2的作用是濾波，C4、C5的作用是過濾直流信號(hào)，把交流信號(hào)送到揚(yáng)聲器中，連接好之后，先不接揚(yáng)聲器，接上電源，那么正負(fù)輸出端之間電壓應(yīng)小于0.1V。接上揚(yáng)聲器，用手觸摸輸入端，揚(yáng)聲器應(yīng)發(fā)出較大的“嗡嗡嗡聲。5、電子元件及其設(shè)備：10千歐姆的電阻4個(gè)、電解電容7個(gè)、9V的直流電源、TDA2822M功率放大集成芯片、面包板1塊、揚(yáng)聲器2個(gè)、導(dǎo)線假設(shè)干。R1、R2是輸入偏置電阻，C1、C2是負(fù)反應(yīng)端的接地電容器，C6、C7時(shí)輸出耦合電容，R3、C4和R4、C5是高次諧波抑制電路，用于防止電路振蕩。6、仿真圖：五、 總結(jié)通過這幾天的課程設(shè)計(jì)，我們組對(duì)一些專業(yè)知識(shí)和電子有了更深入的了解，本次的實(shí)驗(yàn)設(shè)計(jì)

21、是對(duì)課本知識(shí)的現(xiàn)實(shí)使用過程，在這次的實(shí)驗(yàn)中我們要做的不淡單單是運(yùn)用課本上的知識(shí)，更加是對(duì)知識(shí)的檢驗(yàn)和實(shí)際操作的聯(lián)系，鍛煉的我們的動(dòng)手能力和同學(xué)之間的合作關(guān)系，同時(shí)也嘗試著去應(yīng)用自己掌握的知識(shí)。本次電子課程設(shè)計(jì)主要是對(duì)本學(xué)年學(xué)習(xí)的模擬電子技術(shù)，同時(shí)加上電路等知識(shí)，設(shè)計(jì)一些課題。在這幾天的實(shí)訓(xùn)課中我們遇到很多不可防止的難題，尤其是設(shè)計(jì)電路的時(shí)候，有很多時(shí)候不知道如何下手進(jìn)行操作，通過與同學(xué)的探討和搜索資料，最終解決了問題。這次的實(shí)訓(xùn)課程是非常有意義的一次實(shí)訓(xùn)，讓我們?cè)趯W(xué)習(xí)的過程中體驗(yàn)到不同以往的經(jīng)驗(yàn)和知識(shí)，不僅在學(xué)習(xí)上收獲許多，同學(xué)間的相處也更融洽了。總之，這次的實(shí)訓(xùn)課是一次有意義和收獲的課程，也
