Condenser Microphones feem ntau suab zoo dua li cov suab nrov zoo. Yog tias koj tsis paub nrog ob hom microphones no koj yuav xav nyeem txog lawv hauv kab lus Wikipedia no.

en.wikipedia.org/wiki/Microphones#Condenser_microphone

Qhov luv version yog qhov no:

Dynamic microphones muaj cov kauj thiab cov hlau nplaum. Yog li lawv ua zoo li lub tshuab hluav taws xob me me. Lawv tsis xav tau lub zog sab nraud xws li lub roj teeb los ua haujlwm.

Electret condenser microphones muaj ob lub phaj me me (lub capacitor), ib qho uas vibrates thaum muaj suab nrov. Qhov sib txawv ntawm lub peev xwm tau dhau los ua hluav taws xob lub teeb liab los ntawm qhov me me ua hauv lub tshuab ua ntej ua ntej. Yog li hom microphone no xav tau hluav taws xob tam sim no los ua haujlwm. Dhau li ntawm lub suab zoo, condenser microphones feem ntau muaj qhov ua tau zoo dua. Kuj tseem muaj cov condenser microphone cov ntsiab lus feem ntau me dua li qhov hloov pauv thiab ntau lub condenser microphone ntsiab lus yog pheej yig heev.

Yog tias koj tau xav txog kev sim nrog condenser microphone ntsiab lus Kuv xav qhia qhov no muaj los ntawm DigiKey:

668-1596-ND.

Lub suab zoo yog piv rau Radio Shack mic cov ntsiab lus kuv muaj (cov qauv tshwj xeeb tsis muaj los ntawm Radio Shack thiab kuv tsis tau sim qhov tshiab.)

Thaum lub sijhawm kuv tau sau cov lus qhia no kuv tau siv lub mic los ntawm Radio Shack. Kuv muaj ib qho ntxiv ntawm cov no uas tseem nyob hauv pob. Nyob tom qab ntawm pob nws muaj daim duab me me ntawm cov lus teb zaus. Yog tias koj mus rau Shure microphone lub vev xaib, koj tuaj yeem saib cov lus qhia tshwj xeeb rau qhov muaj npe nrov SM58 microphone, RadioShack mic lub siab tshaj cov lus teb ua tau zoo li zoo dua li SM58 tawm mus txog 15 Khz. Nws yuav muaj txiaj ntsig yog tias Xov tooj cua shack teeb tau muaj kev daws teeb meem ntau dua yog li peb yuav paub tseeb qhov twg qhov zaus qis dua txiav tawm qhov tseeb yog. Nws yog qhov ua tau zoo tshaj 10 Khz tau hais hauv qhov tshwj xeeb nyob tom qab ntawm pob. Tsis txhob ua kuv yuam kev. SM58 yog lub microphone zoo rau kev ua yeeb yam nyob qhov twg tus neeg ua yeeb yam tau siv lub suab nrog lub mic yuav luag kov lawv lub ntsej muag. SM58s yog qhov khov heev. Yog tias koj nyiam viav vias koj lub microphone ib puag ncig los ntawm nws lub xov tooj mic thiab qee zaum poob nws rau theem (Roger Daltrey) qhov no yog lub microphone rau koj. Kuv muaj ob lub SM57s (tib lub mic nrog lub tshuab cua me me). Nws tsuas yog tsis yog lub microphone zoo rau qee daim ntawv thov xws li DIY cov phiaj xwm suab. Los ntawm txoj kev. SM58 yuav teeb koj rov qab txog $ 100. RadioShack mic yog lub suab hais lus zoo tab sis yog thaj chaw zoo tiag tiag. Yog tias koj xav siv nws ua lub suab mic koj yuav xav tau lub tshuab cua ua npuas ncauj.

Qee lub cuab yeej siv suab muab hluav taws xob ntawm lub microphone tso rau lub mloog pob ntseg thiaj li tsis xav tau lub hwj chim sab nraud rau lub condenser mic. Qee yam khoom siv tsis ua. Coob leej tawm ntawm lub txee condenser microphones (ua tiav lub microphone suav nrog thiab txuas lub suab thiab txuas lossis txuas txuas uas lees txais lub microphone cable) muaj lub roj teeb uas ua los rau lub zog microphone thiab qee qhov tsis ua. Yog li qee zaum, nyob ntawm seb lub condenser microphone koj tab tom siv thiab dab tsi koj txuas rau, koj xav tau lub roj teeb siv lub zog siv lossis nws yuav tsis ua haujlwm.

Nov yog ib qhov project lom zem microphone uas kuv tau ua ntev los lawm uas yog ib qho laj thawj uas yog vim li cas kuv thiaj ua kuv thawj condenser microphone lub hwj chim muab. Peb siv los pub peb cov tsiaj sab nraum zoov uas yog cov noog qus. Txhawm rau ntxiv rau qhov kev paub kuv tau xaim ib lub xov tooj cua shack mics mus rau lub xov tooj cua uas thaiv thiab khiav lwm qhov kawg mus rau hauv tsev los ntawm kev kaw lub qhov rai ntawm kab (koj tuaj yeem ua qhov no nrog txoj hlua nyias. Lwm qhov kawg ntawm txoj hlua Txuas mus rau lub zog hluav taws xob. Lub zog tso tawm tau ntsaws rau hauv lub roj teeb ua lub tshuab ua suab nrov. Lub microphone tau txuas rau sab hauv qab ntawm lub ru tsev npog npog thiab cov zaub mov tau nyob ntawm lub sam thiaj, 8 ko taw hauv qab. Peb tuaj yeem hnov txhua tweeting zoo li peb nyob sab nraum ib sab ntawm cov zaub mov. zoo li mus pw hauv qab cov hnub qub hauv chav nyob.
