Hauv qhov haujlwm no kuv yuav qhia koj tias vim li cas chav kawm AB lub suab nrov tsis zoo thiab yuav ua li cas chav kawm D lub tshuab hluav taws xob ntawm qhov tod tes txhim kho qhov ua tau zoo no. Thaum kawg kuv yuav qhia koj li cas peb tuaj yeem siv txoj kev xav ntawm kev ua haujlwm ntawm chav kawm D amp rau ob peb yam sib xyaw ua ke txhawm rau tsim peb tus kheej DIY chav kawm D suab amp. Cia peb pib!

Kauj ruam 1: Saib Video

Cov vis dis aus muab koj txhua cov ntaub ntawv koj xav tau los tsim koj tus kheej chav D suab amp. Hauv cov kauj ruam tom ntej no txawm li cas los xij kuv yuav nthuav qhia koj qee cov ntaub ntawv ntxiv los ua kom txoj haujlwm yooj yim dua.

Kauj Ruam 2: Txiav Koj Cov Khoom

Kauj ruam 3: Tsim Circuit Court

Ntawm no koj tuaj yeem pom cov txheej txheem ntawm qhov haujlwm nrog thiab tsis muaj LM386 preamplifier. Xav tias dawb siv cov duab ntawm kuv qhov ua tiav perfboard Circuit raws li kev siv.

Koj tseem tuaj yeem pom cov txheej txheem ntawm EasyEDA:

Kauj ruam 4: Ua tiav

Koj ua nws! Koj tsuas yog tsim koj tus kheej Class D Audio Amplifier!
