Nyob rau hauv lub loj architecture ntawm lub suab system, lub amplifier yog zoo li ib tug haib "conductor", tswj lub amplification thiab tso zis ntawm lub suab signals, thaum lub amplifier Circuit Court board yog lub "hlwb" ntawm no "conductor", ntsiag to ua lub luag hauj lwm tseem ceeb.
Lub luag haujlwm tseem ceeb ntawm amplifier circuit board
Lub hwj chim amplifier circuit board ua ntau yam haujlwm tseem ceeb. Lub luag haujlwm tseem ceeb yog teeb liab amplification. Lub suab tsis muaj zog input teeb liab, txawm hais tias los ntawm CD player, lub computer suab card, lossis lwm qhov chaw suab, zoo li cov kwj deg. Lub amplifier Circuit Board amplifates cov tsis muaj zog cov teeb liab nyob rau hauv ntau theem los ntawm ua tib zoo tsim circuits, hloov lawv mus rau hauv lub zog hluav taws xob signals uas txaus los tsav tus hais lus kom ua suab nrov thiab meej. Cov txheej txheem no zoo li kev txhaj tshuaj txuas ntxiv ntawm lub zog rau hauv lub suab teeb liab, tso cai rau nws los tsim cov ntawv zoo nkauj hauv huab cua.
Qhov thib ob, lub rooj tsav xwm hauv Circuit Court yog lub luag haujlwm rau kev teeb tsa thiab kev tswj hwm. Nws finely kho lub tswv yim suab teeb liab, nrog rau kev kho ntim, ntsuas sab laug thiab txoj cai raws, hloov timbre, thiab lwm yam. Los ntawm kev sib koom tes ua hauj lwm ntawm ib tug series ntawm hluav taws xob Cheebtsam, lub Circuit Court board muaj peev xwm nthuav tawm qhov zoo tshaj plaws auditory nyhuv ntawm suab signals nyob rau hauv txawv scene yuav tsum. Piv txwv li, thaum ua si suab paj nruag classic, kho lub rooj tsav xwm hauv Circuit Court tuaj yeem hais txog cov ntsiab lus thiab txheej txheej ntawm qhov ntsuas; Thaum ua si nrov suab paj nruag, nws tuaj yeem txhim kho qhov kev nkag siab ntawm kev sib dhos thiab bass thaj tsam, ua tau raws li qhov xav tau ntawm cov neeg nyiam suab paj nruag sib txawv.
Kev txheeb xyuas qhov sib xyaw ntawm Circuit Court
Pre amplification circuit: Qhov no yog thawj qhov chaw nres tsheb uas lub teeb liab nkag mus rau hauv lub amplifier circuit board. Lub luag haujlwm tseem ceeb ntawm lub preamplifier Circuit Court yog ua ntej ua kom lub suab tsis muaj zog ntawm lub teeb liab tawm tswv yim, ua kom lub suab nrov ntawm lub teeb liab, kom lub zog txuas ntxiv tuaj yeem ua tau zoo dua. Nws feem ntau yog tsim los ntawm kev ua haujlwm amplifiers, resistors, capacitors, thiab lwm yam khoom. Kev ua haujlwm amplifiers zoo li "cov teeb liab txhim kho masters" ntawm no, ua kom lub suab tsis muaj zog. Resistors thiab capacitors ua lub luag haujlwm hauv kev kho cov teeb liab nce, lim, thiab lwm yam, tshem tawm cov teeb meem ntawm lub teeb liab, ua rau lub suab teeb liab purer, thiab tso lub hauv paus zoo rau kev nthuav dav thiab kev ua haujlwm tom ntej.
Fais fab amplification circuit: Raws li lub hauv paus tseem ceeb ntawm lub amplifier circuit board, lub hwj chim amplification Circuit Court yog lub luag hauj lwm rau ntxiv amplifying lub pre amplified suab teeb liab kom tso zis txaus lub hwj chim tsav tus hais lus. Cov hom hluav taws xob amplifier circuits muaj xws li Class A, Class B, thiab Class A thiab Class B. Class A amplifier circuits muaj tam sim no ntws los ntawm lawv mus rau tag nrho cov teeb liab lub voj voog, ua rau lub suab zoo heev thiab tsis tshua muaj distortion, tab sis kuj tsis tshua muaj efficiency. Chav kawm B amplifier circuits tsuas yog muaj tam sim no dhau los ntawm ib nrab ntawm lub voj voog ntawm lub teeb liab, uas yog qhov ua tau zoo dua, tab sis muaj teeb meem ntawm crossover distortion. Class A thiab Class B amplifier circuits muab cov txiaj ntsig zoo ntawm Chav Kawm A thiab Chav B, ua kom muaj kev ua haujlwm tau zoo thaum txo qis kev cuam tshuam, ua rau lawv siv dav hauv kev siv tswv yim.
Lub zog hluav taws xob: Lub zog hluav taws xob ruaj khov yog lub hauv paus ntawm kev ua haujlwm ib txwm muaj ntawm lub rooj tsav xwm amplifier Circuit Court. Lub zog hluav taws xob yog lub luag haujlwm rau kev hloov lub zog hluav taws xob rau hauv DC lub zog tsim nyog siv rau ntau qhov chaw ntawm lub tshuab hluav taws xob. Nws feem ntau suav nrog transformers, rectification circuits, filtering circuits, thiab voltage stabilization circuits. Transformers txo lossis nce qhov voltage ntawm lub mains kom tau raws li qhov yuav tsum tau muaj voltage ntawm cov circuits sib txawv hauv lub hwj chim amplifiers. Lub rectification circuit hloov AC lub zog rau hauv DC lub zog, thaum lub tshuab lim lim tshem tawm ripple los ntawm DC fais fab mov los ntawm cov khoom xws li capacitors thiab inductors, ua rau cov khoom siv hluav taws xob smoother thiab ruaj khov dua. Lub voltage regulator Circuit Court xyuas kom meej tias cov zis DC voltage tseem nyob ruaj khov nyob rau hauv ntau yam load, muab kev txhawb zog txhawb zog rau ntau yam circuits ntawm lub hwj chim amplifier Circuit Court board.
Feem ntau faults thiab txij nkawm cov ntsiab lus
Kev ua txhaum uas ntsiag to: Thaum lub hwj chim amplifier ntsib qhov ua txhaum uas ntsiag to, tej zaum yuav muaj ntau yam laj thawj. Ua ntej, xyuas seb cov kab hluav taws xob input txuas puas zoo thiab yog tias muaj cov kab hluav taws xob qhib lossis cov neeg tsis zoo. Yog tias lub voj voog zoo li qub, nws yuav yog vim muaj kev puas tsuaj hauv lub preamplifier circuit lossis lub hwj chim amplifier circuit. Piv txwv li, kev ua haujlwm amplifiers yuav raug puas tsuaj vim overheating, overvoltage, thiab lwm yam, ua rau cov teeb liab tsis ua kom zoo. Fais fab transistors kuj tuaj yeem ua txhaum xws li kev puas tsuaj, ua rau nws tsis tuaj yeem tso tawm suab teeb liab. Thaum lub sij hawm tu, nws yog ib qho tsim nyog yuav tsum siv cov cuab yeej xws li multimeters los tshuaj xyuas cov khoom cuam tshuam, txheeb xyuas cov ntsiab lus txhaum ib los ntawm ib qho, thiab hloov cov khoom puas.
Suab distortion fault: Suab distortion kuj yog ib qho ntawm cov faults nyob rau hauv lub hwj chim amplifiers. Qhov no tej zaum yuav yog vim qhov tsis ncaj ncees lawm voltage ntawm lub hwj chim amplifier Circuit Court, ua rau lub transistor ua hauj lwm nyob rau hauv lub nonlinear cheeb tsam, uas ua rau distortion. Tsis tas li ntawd, cov teeb meem xws li kev laus capacitor thiab cov dej xau kuj tseem tuaj yeem cuam tshuam cov lus teb zaus ntawm lub suab, ua rau lub suab tsis sib haum. Thaum kho lub suab distortion faults, nws yog ib qho tsim nyog yuav tsum ua tib zoo kho qhov tsis zoo ntawm lub hwj chim amplifier Circuit Court kom rov ua haujlwm zoo. Nyob rau tib lub sijhawm, capacitors thiab lwm yam khoom siv raug kuaj thiab hloov kho kom raug thiab distortion dawb amplification thiab tso zis ntawm lub teeb liab.
Lub suab tsis zoo: Lub tshuab hluav taws xob muaj lub suab nrov, uas tuaj yeem tshwm sim los ntawm kev lim dej tsis zoo ntawm lub zog hluav taws xob, ua rau muaj kev sib xyaw ntawm lub suab nrov ntawm lub zog hluav taws xob rau hauv lub suab teeb liab, ua suab nrov. Nws kuj tseem yuav yog vim muaj kev cuam tshuam ntawm electromagnetic cuam tshuam ntawm cov khoom ntawm lub rooj tsav xwm hauv Circuit Court, los yog muaj teeb meem xws li kev sib txuas virtual thiab kev sib cuag tsis zoo, uas tuaj yeem ua rau lub suab nrov. Thaum kho, nws yog ib qho tsim nyog yuav tsum tau xyuas seb lub lim dej capacitor ntawm lub hwj chim Circuit Court puas puas thiab hloov nws yog tias tsim nyog. Rau cov teeb meem ntawm electromagnetic cuam tshuam, lawv tuaj yeem daws tau los ntawm kev ua kom zoo ntawm kev xaim ntawm lub rooj tsav xwm Circuit Court, ntxiv kev tiv thaiv kev tiv thaiv, thiab lwm yam. Nyob rau tib lub sijhawm, ua tib zoo tshuaj xyuas cov pob qij txha ntawm lub rooj sib tham hauv Circuit Court kom ntseeg tau tias lawv tau ruaj khov thiab tshem tawm cov teeb meem xws li kev sib txuas virtual.
Zoo sib xws rau lub suab zoo
Kev tsim thiab kev ua haujlwm ntawm amplifier Circuit Court board muaj kev txiav txim siab ntawm lub suab zoo. Kev tsim hluav taws xob zoo hauv Circuit Court kom ntseeg tau tias cov teeb liab suab khaws cov ntsiab lus thiab qhov sib txawv ntawm qhov tseem ceeb ntawm lub teeb liab mus rau qhov siab tshaj plaws thaum lub sij hawm amplification thiab ua. Ib qho kev tsim hluav taws xob tsim nyog tuaj yeem txo qhov cuam tshuam ntawm cov teeb liab, ua kom lub suab ntshiab thiab pom tseeb. Piv txwv li, cais cov qauv ntawm cov kab teeb liab analog thiab cov kab teeb liab digital kom tsis txhob cuam tshuam los ntawm cov teeb liab digital ntawm cov teeb liab analog.
Kev siv siab -cov khoom siv hluav taws xob ua tau zoo ntawm lub rooj tsav xwm hluav taws xob kuj tseem ceeb heev. Cov capacitors zoo tuaj yeem muab cov kev lim dej ruaj khov ntau dua, ua rau lub suab qis qis dua thiab muaj zog dua, thiab lub zog loj dua thiab ci dua. Tsis tshua muaj suab nrov ua haujlwm amplifiers thiab fais fab transistors tuaj yeem txo cov teeb liab distortion, tso cai rau txhua daim ntawv suab paj nruag kom rov tsim dua tshiab, muab cov neeg mloog nrog kev paub txog kev mloog zoo.
