Microphones raug muag hauv ntau tus nqi. Cov qauv pheej yig yog tsawg dua $ 50, thaum cov nqi kim tuaj yeem ntxiv txog ntau txhiab daus las. Txawm hais tias muaj ntau yam xaiv los ntawm, yuav luag txhua lub microphone poob rau hauv ib qho ntawm ob hom yooj yim: dynamic thiab condenser. Lwm yam thiab tsis tshua muaj hom koj yuav ntsib yog ribbon microphone. Txawm hais tias txhua tus yog transducer uas khaws thiab ntes lub suab, cov txheej txheem ntawm kev tsim hluav taws xob tso zis hluav taws xob yog qhov txawv.
Txawm li cas los xij, nyob ntawm koj qhov kev xav tau thiab cov xwm txheej, ib qho yuav yog qhov kev xaiv zoo dua rau lwm qhov. Qhov khoom yog, nws nyuaj rau qhia ntau hom sib nrug los ntawm saib lub microphone.
- siv sab nraum zoov.
- Live ua yeeb yam.
- Kawm xov xwm thiab xam phaj.
- Kev kaw cov qib siab.
- qhia suab thiab seev suab.
- Thaum koj xav tau ib yam khoom ruaj khov.
- siv sab hauv.
- Studio ua yeeb yam.
- Podcasting thiab xov xwm.
- Sau kom meej thiab raug.
- Higher zaus vocals thiab instruments.
- Thaum durability tsis yog qhov tseem ceeb.
Txawm tias koj npaj yuav tsim podcast lossis tshaj tawm xov xwm, kaw suab paj nruag, lossis lom zem yav tsaus ntuj ntawm karaoke hauv tsev, lub microphone muaj kev cia siab tau ua lub luag haujlwm tseem ceeb. Txawm hais tias feem ntau cov microphones lo rau hauv daim ntawv paub, koj tuaj yeem pom cov khoom nthuav tawm tswv yim nrog cov duab sib txawv thiab ntau thiab tsawg. Raws li nrog rau lwm hom kev siv tshuab niaj hnub, microphones nthuav qhia ntau yam tshwj xeeb thiab cov yam ntxwv muaj txiaj ntsig.
Dynamic Microphones
- Tsis xav tau lub zog lossis roj teeb.
- Yooj yim lis cov suab nrov thiab cov twj paj nruag.
- Tswj pheej yig dua.
- Feem ntau siv tau ntev dua li condenser microphones.
- Ideal rau sab nraum zoov thiab nyob ib puag ncig kaw.
- Feem ntau yuav tsum muaj lub suab nrov ntxiv kom tau txais txiaj ntsig zoo tshaj plaws.
- Tsis yog rhiab lossis teb raws li condenser microphones (tshwj xeeb ntawm cov zaus siab dua).
- zaus teb tuaj yeem sib txawv nyob ntawm tus qauv tsim thiab daim ntawv thov.
Kev ua haujlwm ntawm lub microphones muaj zog tuaj yeem cuam tshuam nrog cov neeg hais lus ib txwm muaj tab sis rov qab. Nrog ib tus neeg hais lus ib txwm muaj, lub suab teeb liab tawm ntawm qhov chaw mus rau lub suab coil txuas rau lub khob hliav qab (tseem hu ua diaphragm). Thaum hluav taws xob (lub teeb liab suab) ncav cuag lub kauj, ib qho chaw sib nqus yog tsim (electromagnet txoj cai), uas cuam tshuam nrog cov hlau nplaum ruaj khov nyob tom qab lub kauj. Kev hloov pauv ntawm lub zog ua rau cov hlau nplaum sib nqus kom nyiam thiab tawm tsam, yuam kom lub khob txuas txuas rau vibrate rov qab thiab tawm, uas ua rau lub suab tsis zoo uas peb tuaj yeem hnov.
Kev tsim kho ruaj khov thiab tsis tshua muaj siab
Raws li cov neeg hais lus ib txwm muaj, lub microphones zoo heev ntawm kev tuav cov ntim siab nrog kev sim thiab siv technology. Dynamic microphones feem ntau tsis tshua muaj nqi rau kev tsim khoom, thiab cov khoom siv hluav taws xob sab hauv zoo li rugged ntau dua li lawv cov condenser counterparts. Qhov no txhais tau hais tias lawv muaj peev xwm coj tau ib tug ntaus thiab tuav ib tug nco-zoo tagnrho rau active tuav nyob rau hauv ob txhais tes tiv thaiv tawm nws mounted rau ib tug ruaj khov. Zuag qhia tag nrho durability los ntawm kev tsim kho zoo. Tsuas yog vim hais tias lub microphone tsis muaj zog tsis tau lees tias nws tau tsim kom ntev, cia nyob ib leeg outlast lub condenser microphone.
Dynamic microphones tsis rhiab li condenser microphones. Rau feem ntau, vim tias muaj cov qauv kim uas xa cov txiaj ntsig zoo kawg. Qhov no feem ntau yog vim qhov hnyav ntawm cov hlau nplaum thiab coil, uas inhibits sai npaum li cas lub khob hliav qab teb rau lub suab tsis. Thaum muaj qhov tsis zoo, nws tsis yog ib txwm ua phem. Tsawg rhiab heev thiab cov lus teb tsawg dua feem ntau txhais tau hais tias tsawg dua cov ntsiab lus hauv cov kaw, tab sis qhov ntawd kuj suav nrog cov suab nrov thiab tsis xav tau.
Condenser Microphones
- Tsim lub suab muaj zog yam tsis muaj preamp.
- Ntse ntau rhiab heev rau khaws cov suab nrov thiab nyob deb.
- Zoo dua dynamic zaus teb.
- Ideal rau sab hauv tsev thiab ntsiag to kaw ib puag ncig.
- Yuav tsum muaj lub zog sab nraud (phantom) lossis roj teeb.
- Txoj kev nkag siab zoo tuaj yeem ua rau muaj kev cuam tshuam hauv qee qhov xwm txheej.
- Yuav kim dua.
- Ntau cov khoom siv hluav taws xob tsis zoo dua li ntawm cov microphones dynamic.
Kev ua haujlwm ntawm condenser microphones piv rau tus hais lus electrostatic tab sis rov qab. Nrog tus hais lus electrostatic, ib lub diaphragm nyias raug tshem tawm ntawm ob daim phiaj (tseem hu ua stators) txuas nrog lub zog hluav taws xob. Lub diaphragm yog tsim los nrog cov khoom siv hluav taws xob los tuav tus nqi ruaj khov thiab cuam tshuam nrog cov kab sib chaws.
Cov suab paj nruag ntawm qhov sib npaug ntawm lub zog tab sis qhov sib txawv polarity raug xa mus rau txhua daim phiaj. Thaum ib daim phiaj thawb lub diaphragm, lwm daim phiaj rub nrog lub zog sib npaug. Raws li daim phiaj sib hloov los ntawm kev hloov pauv hauv qhov hluav taws xob, lub diaphragm txav mus los, tsim cov suab nrov peb tuaj yeem hnov. Tsis zoo li dynamic microphones, condensers tsis muaj hlau nplaum.
Sensitive thiab teb
Raws li cov neeg hais lus electrostatic, cov txiaj ntsig tseem ceeb ntawm condenser microphones yog txhim kho rhiab heev thiab cov lus teb. Los ntawm kev tsim, lub diaphragm nyias muaj peev xwm ua rau muaj kev cuam tshuam sai thiab nyob deb ntawm cov suab nrov mus ncig.
Qhov no yog vim li cas condenser microphones yog qhov tseeb tshwj xeeb thiab paub meej ntawm kev ntes cov subtleties nrog cov lus meej meej, uas ua rau cov no zoo tagnrho rau cov ntaub ntawv kaw lus siab-tshwj xeeb yog cov suab nrov lossis ntau zaus ntau dua. Thiab vim li cas cov khoom siv hluav taws xob tau tsim los ua haujlwm, condenser microphones tuaj yeem pom nyob rau hauv ntau hom duab thiab ntau thiab tsawg dua li cov microphones dynamic.
Muaj feem cuam tshuam rau kev puas tsuaj thiab suab lus tawm tswv yim
Txawm hais tias kev txhim kho rhiab heev yuav zoo li zoo heev, muaj qee qhov tsis zoo. Condenser microphones raug cuam tshuam, xws li thaum sim kaw suab nrov lossis suab nrov. Cov microphones no kuj raug rau lub suab tawm tswv yim. Qhov no tshwm sim thaum lub suab tau txais los ntawm lub microphone dhau los ntawm tus neeg hais lus thiab tau rov qab los ntawm lub microphone nyob rau hauv ib lub voj nruam. Cov no tuaj yeem khaws cov suab nrov tsis xav tau, tshwj xeeb yog tias koj tsis nyob hauv chav nyob ntsiag to lossis suab pov thawj. Piv txwv li, lub condenser microphone yuav tsis yog qhov zoo tshaj plaws los siv rau kev sib tham sab nraum zoov lossis kaw thaum muaj cua, nag, tsheb khiav, lossis lwm yam suab nrov tom qab. Txawm hais tias cov suab nrov no tuaj yeem raug tshem tawm nrog software rau kho cov suab paj nruag thiab suab kaw, nws yuav tsum tau ua ib kauj ruam ntxiv.
Kev Txiav Txim Kawg
Txawm hais tias ob qho tib si qhia txog qhov muaj zog ntsig txog kev ua haujlwm, muaj lwm yam los xav txog yog tias koj tab tom nrhiav rau lub microphone tshiab lossis hloov pauv. Ntau lub microphones tau tsim los nrog kev siv tshwj xeeb hauv siab, yog li nws yog qhov zoo tshaj plaws los siv nrog kev xav tau. Tej zaum koj yuav xav tau lub microphone uas yog tshwj xeeb rau: cov hom phiaj dav dav, kev ua yeeb yam lossis cov xwm txheej, PA systems, kev sib tham, studio kaw, suab, suab paj nruag, suab paj nruag, suab paj nruag, suab paj nruag, suab paj nruag, suab paj nruag, suab paj nruag, suab paj nruag, suab paj nruag thiab suab paj nruag los yog raws li cov lus teb zaus, thiab podcasting thiab newscasting. Koj tuaj yeem pom cov kev xaiv zoo tshaj plaws nrog rau hla ntau lub npe.
Microphones kuj muaj qhov sib txawv ntawm cov lus teb ntau zaus (xyuas cov chaw tsim khoom tshwj xeeb), uas ua rau ib hom zoo dua li lwm tus, nyob ntawm seb txhua tus siv li cas. Qee tus kuj tau tsim los kho cov ntaub ntawv kaw tseg thiab nruab nrab, thaum lwm tus ntxiv kev txhim kho rau tag nrho cov duab. Qhov no tuaj yeem ua rau xim xim lossis pom qhov loj ntawm lub suab.
Lwm yam tshwj xeeb los sib piv thiab xav txog yog teeb liab-rau- suab nrov piv, siab tshaj plaws suab siab (suab suab), tag nrho kev sib haum xeeb distortion, polar qauv, thiab rhiab heev.
Thaum kawg, txoj cai microphone yog lub suab zoo tshaj plaws rau koj lub pob ntseg thaum ua tau raws li koj xav tau siv.
