Kev sib xyaw ua ke audio power amplifiers muaj ntau heev thiab siv rau ntau yam khoom siv hluav taws xob. Lawv yog cov cuab yeej siv tau yooj yim, yog li ntawd, muaj cov txuj ci los ua haujlwm nrog hlau soldering, txhua tus tuaj yeem sib dhos xws li cov cuab yeej siv ntawm lawv lub hauv caug.
Cov Lus Qhia
Kauj ruam 1
Rub tawm hauv Is Taws Nem lossis tsim kho koj tus kheej daim duab hluav taws xob ntawm lub cuab yeej. Raws nws, sau cov npe tsim nyog rau lub suab nrov zoo ntxiv thiab mus rau tom khw xov tooj cua. Koj yuav xav tau: 4 lub zog, 4 resistors, luam tawm hauv pawg thawj coj saib, khoom siv rau etching lub rooj tsavxwm, tin, rosin thiab microcircuit. Cov ntawv nthuav dav kawg yog qhov tseem ceeb tshaj plaws, vim nws txiav txim siab lub zog ntawm lub zog yav tom ntej. Piv txwv li, koj tuaj yeem siv TDA-based microcircuit, uas muaj peev xwm xa 35 W ib channel rau ntawm qhov ntsuas hluav taws xob ntawm 18 V. Cov kab ke no tseem muaj kev tiv thaiv luv luv, ua haujlwm ntau dhau thiab ua kom dhau, tsis siv neeg kaw yog lub teeb liab qhov hluav taws xob ploj, thiab lwm yam haujlwm muaj txiaj ntsig zoo.
Kauj ruam 2
Los ntawm kev txuas cov raws ntawm lub microcircuit rau tus choj, koj tau txais ib qho-channel zog amplifier ntawm 70 watts. Xaiv cov chav kawm D chip uas yuav muab koj lub suab nrov dua ntawm cov ntsuas hluav taws xob tsawg.
Kauj ruam 3
Npaj cov PCB, kos cim thiab pib soldering. Sau tag nrho cov khoom sib txuas ntawm lub zog txuas ntxiv hauv qhov kev txiav txim kom raug. Nco ntsoov tias txhua yam khoom muaj muag zoo zoo. Tom qab ntawd siv lub ntsuas thiab ntiv nplhaib lub ntsiab sib txuas. Nws yog qhov tsim nyog tias cov teeb liab kis tau hla txhua qhov ntawm lub suab txuas ntxiv, tsis li ntawd qhov xav tau thiab lub zog yuav tsis tau txais.
Kauj ruam 4
Xaiv rooj plaub rau hais kom nrov zog. Ua kom zoo li no, koj tuaj yeem siv cov neeg hais lus qub lossis dhos nws tus kheej los ntawm cov khoom siv seem. Xav txog cov cuab yeej ua kom txias. Piv txwv, lub tshuab ntsuas hluav taws xob thiab lub tshuab ua cua txias tuaj yeem txuas nrog ib sab. Tom qab ntawd, ua tib zoo nruab lub rooj tsavxwm soldered rau hauv rooj plaub. Nqa cov xov hlau.
Kauj ruam 5
Txuas lub suab txuas ntxiv rau tus neeg hais lus thiab tshawb xyuas seb nws puas ua haujlwm. Yog tias cov cuab yeej tsis ua haujlwm, ces nws yog qhov yuav tsum tau rov ua hluav taws xob hauv Circuit Court thiab kuaj qhov tseeb ntawm qhov sib txuas, xa mus rau hluav taws xob Circuit Court ntawm cov amplifier.
