Lub voj voog ntawm lub suab nrov amplifier yog qhov nyuaj. Yuav ua li cas ua kom lub suab nrov ntawm koj tus kheej

Nyob rau hauv tsab xov xwm no, peb yuav xav txog qhov "Circuit Court Amplifier" rau kev siv. Nyob ntawm seb, nyob rau hauv dab tsi cheeb tsam yuav tsum tau siv los ntawm lub amplifier (kuj hu ua VLF - hwj chim tsawg zaus), nws yuav muaj ntau qhov ntev thiab complexity ntawm lub tsev schemes. Hauv tsab xov xwm, peb hom kev amplifiers - ntawm transistors, microcircuits thiab teeb - yuav raug chwv ib zaug. Thiab nws yog tsim nyog pib nrog lub yav tas.

Teeb ULF

Cov no tuaj yeem pom muaj nyob hauv cov cuab yeej siv qub - televisions, radios. Dua li ntawm qhov ua tsis ncaj, qhov txheej txheem no tseem nyiam nrog cov neeg nyiam suab paj nruag. Muaj ib lub tswv yim tias lub raj suab tau ntau dua thiab zoo nkauj tshaj qhov "digitized". Nws yog heev tau, nyob rau hauv txhua rooj plaub, xws li ib qho kev tshwm sim, raws li los ntawm lub teeb, yog tsis tiav siv transistor circuits. Nws yog ib nqi sau cia hais tias lub amplifier Circuit Court suab (lub simplest, siv lub teeb) yuav pom tau hais ntawm tsuas yog ib transistor.

Hauv qhov no, lub teeb liab yuav tsum tau pub rau cov xov tooj cua tube kab sib chaws. Kev thuam qhov siab yog siv rau cathode - nws yog kho los ntawm kev xaiv qhov ua hauj nyob hauv Circuit Court. Mov voltage (saum toj 150 volts) yog siv rau anode los ntawm tus capacitor thiab cov thawj winding ntawm lub transformer. Raws li, qhov thib ob qhov sib ntswg yog txuas nrog lub suab paj nruag. Tab sis qhov no yog ib qho yooj yim Circuit Court, tiam sis hauv kev xyaum nws feem ntau siv ob los yog peb-theem qauv, uas muaj qhov kev paub ua ntej thiab qhov kawg siab (rau high-power yaj).

Disadvantages thiab qhov zoo ntawm teeb lub teeb

Dab tsi yog qhov tsis zoo ntawm qhov teeb meem siv teeb? Nws tau hais saum toj no tias qhov anode voltage yuav tsum yog siab tshaj 150 volts. Ntxiv rau qhov no, nws tseem yuav tau muaj AC voltage ntawm 6.3 V rau noj cov ntsiab lus ntawm lub teeb. Qee lub sij hawm 12.6 V yuav tsum muaj, vim muaj cov teeb muaj lub qhov cua kub. Li no tus xaus - ib tug lossis loj hwj chim mov Circuit Court, qhov yuav tsum tau siv loj heev transformers.

Tab sis muaj cov kev zoo uas qhov txawv qhov teeb pom kev siv tshuab los ntawm transistor: simplicity ntawm installation, durability, nws yog yuav luag tsis ua kom tag nrho Circuit Court. Tshwj tsis yog tias koj xav tau txoj hlua ntawm lub teeb kom tawg nws. Dab tsi yuav tsis tau hais txog cov transistors - ib qho kev ua kom siab tshaj li qhov ntsuas los yog lub dav hluav taws xob tau yooj yim txav cov qauv ntawm kev hloov. Qhov teeb meem qub nrog microcircuits.

Transistor circuits

Saum toj no yog daim duab ntawm lub suab nrov ntawm cov hlauv ntawm transistors. Raws li koj tau pom, nws yog qhov nyuaj - ntau cov khoom siv uas cia siv tag nrho lub zog ua hauj lwm. Tab sis yog tias koj tawg lawv mus rau hauv me me, nws hloov tawm hais tias tsis yog txhua yam yog nyuaj heev. Thiab tag nrho Circuit Court ua haujlwm nyob rau hauv ntau txoj kev zoo ib yam li ib qho kev piav qhia saum toj no rau lub tshuab nqus tsev triode. Qhov tseeb, tus semiconductor transistor tsis muaj dab tsi ntau tshaj li ib qho kev sib tw.

Qhov yooj yim tsim yog ib qho kev sib cog lus ntawm ib qho chaw ntawm lub semiconductor, nyob rau ntawm lub hauv paus ntawm peb qhov hluav taws xob tau muab los ntawm ib zaug: los ntawm kev muaj hwj huam los ntawm kev tiv thaiv zoo thiab los ntawm cov xov hlau tsis zoo, thiab kuj los ntawm lub teeb liab. Lub teeb liab ntawm lub collector raug tshem tawm. Cov lus saum toj no yog ib qho piv txwv ntawm lub suab hloov ntawm lub suab nrov (qhov nyuaj tshaj plaws rau ntawm transistors). Nws tsis siv nyob rau hauv nws daim ntawv dawb huv.

Microchips

Ib tug ntau dua tshiab thiab zoo amplifier yuav tsum nyob rau daim tawv nyias. Kuj zoo rau hnub no lawv cov ntau yam. Qhov yooj yim Circuit Court ntawm lub suab amplifier ntawm lub nti muaj tsawg kawg nkaus ntawm cov ntsiab lus. Thiab kom nws tus kheej zoo ULF tuaj yeem ua rau txhua tus neeg uas paub txog kev daws cov kab mob hnyav ntau dua los yog tsawg dua. Raws li txoj cai, lub chips muaj ob peb lub capacitors thiab resistances.

Tag nrho lwm cov ntsiab tsim nyog rau kev ua haujlwm yog muaj nyob rau hauv lub siv lead ua nws tus kheej. Tab sis qhov tseem ceeb tshaj plaws yog khoom noj khoom haus. Rau qee qhov tsim, koj yuav tsum siv cov khoom siv fais fab tuag. Feem ntau qhov teeb meem tshwm sim precisely nyob rau hauv lawv. Lub chips uas xav tau lub hwj chim zoo li no, piv txwv li, yog qhov nyuaj rau kev siv lub tshuab hluav taws xob.

Pab "tshuaj pleev"

Txij li thaum tham txog amplifiers on microcircuits tau pib, nws tsis yog superfluous hais tias lawv yuav siv nrog timbrocks. Tshwj xeeb rau cov khoom siv xws li cov khoom siv microcircuits. Lawv muaj tag nrho cov khoom tsim nyog, nws tshua tsuas mus kom ncav tag nrho cov cuab yeej.

Thiab koj yuav muaj sijhawm los kho lub sijhawm ntawm lub suab nkauj. Coupled nrog LED EQ, nws yuav tsis tsuas yog yooj yim, tab sis kuj yog ib tug zoo nkauj txhais ntawm visualizing lub suab. Thiab feem ntau nthuav rau tsheb suab enthusiasts yog, ntawm chav kawm, tau ntawm txuas ib subwoofer. Tab sis nws yog tsim nyog tau txais kev faib tawm ib ntu, vim hais tias lub ncauj lus nthuav thiab qhia.

Lub subwoofer yog ib qho yooj yim

Txhawm rau xa ib lub subwoofer, koj yuav tsum ua kom tau ib qho kev sib txawv ntawm cov tshuab mono. Yog hais tias koj saib ntawm cov qauv tsim ntawm amplifiers, ces nyob rau hauv ib rooj plaub lawv muaj ib lub tso suab thiab mono amplifiers. Thawj txuas mus rau cov neeg hais lus, thiab ob - mus rau subwoofer. Ntxiv mus, nyob rau hauv lub thib ob yog ib tug me me feature - tuaj txoos ua ke nyob rau kev nkag ntawm tsawg-pass lim. Nyob ntawm nqe qeb, qhov lim no yuav kho tau lossis tsis tau. Ua ke kom muaj lub suab nrov zoo nrog koj txhais tes, lub voj voog uas yog siv rau ntawm microcircuits, nws muaj peev xwm nyob rau hauv ib qho teeb meem ntawm feeb, txij thaum tsis muaj dab tsi yog nyuab nyob rau hauv no.

Qhov yooj yim LPF yog ob peb lub cev tiv thaiv thiab cov kaw lus nruab nrog raws li lub tswv yim saum toj no. Thaum twg qhov Circuit Court tau qhib rau, lub teeb liab nrog qee zaus nyob rau ntawm 30-60 Hertz yog siv rau cov tswv yim ntawm qhov kev hloov. Nws yog qhov sib ncaib uas tau tsim los ntawm ULF thiab xa mus rau lub woofer. Nws yuav tsum tau muab sau tseg hais tias lub tswv yim uas tsis muaj-pass lim yog tsim nyog los muab lub ntim tswj.

Cov txiaj ntsig ntawm cov qauv kev hloov tshiab tam sim no ntawm microcircuits

Thaum pom tias txhua hom kev ua tau zoo, peb tuaj yeem xaus: cov khoom sib tw thiab cov yooj yim tshaj plaws yog ua nyob rau cov caij nyoog niaj hnub no. Ntau ntawm microcircuits yog ua rau cov neeg tsis muaj zog ntau zaus. Ua ib qho piv txwv, peb tuaj yeem hais qhov ULF ntawm TDA hom nrog ntau hom kev qhia zauv.

Lawv siv txhua txhia qhov chaw, vim tias muaj ob qho tsis muaj zog thiab muaj hwj chim siab microcircuits. Piv txwv li, rau cov tshuab computer tau tham nws yog qhov zoo tshaj plaws uas siv cov chips uas muaj hwj chim tsis tshaj li ntawm 2-3 watts. Tab sis rau kev siv tshuab fais fab lossis tsev ua yeeb yam hauv tsev, nws yog ntshaw kom siv chips nrog lub hwj chim ntau tshaj 30 watts. Tab sis mloog mus rau lub fact tias cov kev xav tau los mus tiv thaiv hwj chim amplifiers suab. Cov circuits yuav tsum muaj lub fuse uas yuav tiv thaiv luv Circuit Court hauv Circuit Court.

Ntxiv rau, thiab qhov ntawd tsis tas yuav muaj hwjchim loj heev, yog li koj siv tau yooj yim, piv txwv li, los ntawm lub laptop, PC, qub MFU (tshiab, raws li txoj cai, lub hwj huam nyob sab hauv). Qhov yooj yim ntawm installation yog ib yam dab tsi uas tseem ceeb rau cov pib hams. Qhov tsuas yog qhov uas yuav tsum tau rau cov khoom siv no yog qhov txias txias. Yog tias nws yog ib qhov txheej txheem haib, koj yuav tsum tau nruab ib qhov yuam kev ib los yog ob peb lub thawv txias rau lub tshuab hluav taws xob.
