Nkauj guitar yog ib qho cuab yeej nrov tshaj plaws. Yuav luag txhua tus tuaj yeem ua si acoustic guitar. Hmoov tsis zoo, lub suab tsis muaj amplification tsis yog ib txwm txaus rau cov twj paj nruag acoustic, qhov no kuj siv tau rau guitars ntawm hom no. Txhawm rau ua kom lub suab nrov dua thiab nrov dua, tus nqa tuaj yeem pab tau - nws hloov lub suab mus rau hauv qhov hluav taws xob thiab tso cai rau koj ua kom nrov nrov. Qhov no tuaj yeem pab tau ntawm qhov chaw gig lossis rov ua dua thaum koj xav kom haum lub suab paj nruag guitar rau hauv ntu ntu.
Nyob rau hauv tsab xov xwm no, peb yuav saib yuav ua li cas ua DIY acoustic guitar pickup.
Los ntawm cov hlau nplaum
Yog li, cia peb pib nrog hom nrov tshaj plaws ntawm guitar amplification - cov khoom sib nqus. Nyob rau hauv thiaj li yuavYuav kom ua tau ib tug pickup rau ib tug acoustic guitar nrog koj tus kheej tes los ntawm hlau nplaum, koj yuav xav tau ib tug pickup los ntawm ib tug hluav taws xob guitar. Cov qauv ntawm cov hluav taws xob guitar haum txig rau hauv cov qauv ntawm cov cuab yeej rau txoj hlua zoo tib yam - nyob rau hauv rooj plaub no, koj yuav tsum tau ua kom haum rau txhua qhov ntawm cov hlau nplaum raws nraim rau txoj hlua kom lub suab xa mus kom meej thiab meej li sai tau.
Txhawm rau kom koj rho tawm lub suab los ntawm kev khaws cia, koj yuav tsum tau khiav cov kev sib cuag ntawm koj ib leeg-coil lossis humbucker hauv lub cev ntawm guitar thiab ua lub qhov rau kev tawm. Cov tom kawg yuav ua raws li tus qauv qhov (socket) hom "Jack". Yog tias txhua yam ua tiav yog lawm, tom qab ntawd thaum koj txuas lub guitar mus rau lub tshuab hluav taws xob combo lossis daim npav suab, koj yuav tau txais lub teeb liab huv si uas tuaj yeem tig tau nrov dua ntawm lub cuab yeej.
Handmade pickup rau acoustic guitar zoo kawg nkaus suav lub suab. Koj tuaj yeem sim txawm tias: cua me me rau ntawm lub tshuab hluav taws xob, qhov no yuav ua rau me ntsis overload thiab lub suab nruj dua.
Humbucker lossis ib leeg?
Peb pom zoo kom muab ib lub kauj rau cov acoustic guitars, vim hais tias humbuckers yog cov ntsiab lus muaj zog dua thiab siv rau hauv hluav taws xob guitars kom ua tiav lub suab muaj zog thiab hnyav hnyav. Rau acoustics, qhov no tsis yog qhov tsim nyog, koj tsuas yog xav tau kom nthuav dav koj lub teeb liab huv si, thiab ib qho yuav ua tau zoo nrog qhov no.
Los ntawm piezoelectric ntsiab
Yuav ua kom piezo tuaj tos, koj yuav tsum tau xyuam xim rau sab hauv ntawm lub cev guitar. Qhov tseeb yog qhov ntawdLub piezo pickup yog qhov rhiab heev thiab yuav tsim cov suab sib txawv thaum muab tso rau hauv ntau qhov chaw ntawm lub cev guitar.
Txhawm rau ua tus khaws rau acoustic guitar nrog koj tus kheej txhais tes los ntawm cov khoom piezoelectric, koj yuav xav tau:
- the piezoelectric element nws tus kheej;
- jack-jack cable;
- end-pin-jack tip.
Lub piezoelectric muaj nyob hauv ntau cov menyuam yaus cov khoom ua si lossis cov khoom siv hluav taws xob, nws tsis tas yuav yog qhov tshiab. Qhov tseeb, txhua yam koj xav tau yog lub peev xwm los solder, vim hais tias ib kawg ntawm lub cable yuav tsum tau soldered rau lub piezo keeb:
- Nws muaj sab nrauv thiab sab hauv. Thaum koj qhib lub cable ntawm ib sab, koj yuav pom 2 cov xov hlau nyob ntawd, thiab ib qho yuav tsum tau muab khi rau sab hauv, thiab ib sab mus rau sab nraud.
- Piezo ntsiav tshuaj nws tus kheej tuaj yeem muab zais rau hauv rooj plaub kom tsis txhob pom cov xov hlau tiv tauj, thiab txuas los ntawm sab hauv mus rau cov khoom tawm los ntawm "jack".
Yog li koj tau txais qhov me me DIY acoustic guitar tuaj tos ntawm qhov tsis raug nqi.
Los ntawm tus hais lus
Txawm li cas los xij nws yuav suab txawv txawv, tuaj yeem tau txais los ntawm cov neeg hais lus, txawm tias tsis muaj kev paub tshwj xeeb hauv xov tooj cua engineering. Yog li, ib qho khoom siv hluav taws xob acoustic sib sau ua ke los ntawm lub mloog pob ntseg (tseem muaj ob tus neeg hais lus me me ua rau hauv lub mloog pob ntseg) yuav suab zoo yog tias txhua yam ua tiav raug.
Hauv qhov no koj yuav xav tau:
- 3 lub mloog pob ntseg;
- ob peb lub xov tooj los txuas cov neeg hais lusua ke;
- loj shielded hlau jack.
Thiab tam sim no yuav ua li cas:
- Ua tib zoo tshem cov neeg hais lus tawm ntawm lub mloog pob ntseg thiab muab khi rau ntawm lub qhov (socket) thiab lub caj dab guitar.
- Txhua tus hais lus me me yuav tsum tau muab khi rau hauv ob txoj hlua. Ua li no, ib txoj hlua rau guitar yuav raug them tag nrho los ntawm peb tus neeg hais lus.
- Ua-nws-koj tus kheej khaws rau acoustic guitar li no thawj zaug koj yuav ua tsis tau yog tias koj tsis txuas tag nrho cov xov hlau hauv koob. Xav rov qab mus rau cov chav kawm physics theem pib: tsuas yog ib lub xaim mus ntawm txhua tus hais lus mus rau lwm qhov.
- Thaum tag nrho peb txuas, muab cov xov hlau sib txuas ua ke kom cov neeg sib cuag tsis txav deb ntawm ib leeg, txwv tsis pub ib tus neeg hais lus yuav tsum tsis ua haujlwm.
- Tom qab qhov kawg, coj cov xaim mus rau sab nraub qaum ntawm lub guitar (tejzaum nws sab hauv) thiab txuas lub jack rau nws cov tswv yim. Twb tau los ntawm cov tswv yim no yuav mus rau cov hlau tuab tshaj plaws rau lub suab nrov.
Yog li, thaum lub cuab yeej qhib, cov neeg hais lus yuav nyeem cov teeb liab thiab xa cov kev vibrations mus rau lub amplifier, thiab koj yuav tau txais cov khoom yooj yim tshaj plaws.
Microphone
Txoj kev yooj yim tshaj plaws thiab tsis tseem ceeb tshaj plaws los ua kom lub suab nrov yog embed lub microphone rau hauv acoustic guitar. Yog tias koj lub guitar muaj EQ ntawm lub nraub qaum, ces lub microphone twb nyob ntawd, thiab txhua yam koj yuav tsum ua yog tig lub suab rau nws. Cov kev teeb tsa ntawm qhov sib npaug no tso cai rau koj hloov lub suab tsis muaj kev cuam tshuam rau kev ncaj ncees ntawm lub suab.
Tab sis yog tias koj tseem tsis muaj lub suab nrov sab hauv, cesKoj tuaj yeem ua kom lub suab nrov nrog lub suab zoo tib yam microphone. Ua-nws-koj tus kheej tuaj tos rau lub acoustic guitar los ntawm lub microphone yog qhov yooj yim tshaj plaws los ua:
- Koj tsuas yog yuav tsum tso lub microphone rau hauv lub lawj kom lub suab tsis txawv txav thiab lub microphone tsis tuaj yeem nqa lub suab nrov.
- Txhua yam yooj yim ntawm no - deb ntawm qhov hluav taws xob koj zais lub microphone hauv guitar, lub suab tsis tshua muaj zog nws yuav kaw.
- Lub microphone tso zis tuaj yeem hloov pauv thiab sab laug raws li nws yog, vim tias koj yuav txuas lub guitar mus rau qhov sib xyaw console lossis ncaj qha mus rau lub khoos phis tawj, thiab tsis mus rau lub amplifier.
Txoj kev no zoo meej rau cov neeg ua yeeb yam hauv kev hais kwv txhiaj lossis nyob. Txhua yam koj xav tau yog tus hais lus lossis lub txee, tsis xav tau lub tshuab hluav taws xob hauv qhov no.
Nyob hauv subway los yog hauv qab txoj kev, cov neeg ntaus suab paj nruag feem ntau siv lub microphones, vim tias qee lub sijhawm nws tuaj yeem poob dej, tsis zoo li lwm cov khoom hauv tsev.
Zaj lus
Ua-nws-koj tus kheej khaws rau lub suab seev suab paj nruag kuj tuaj yeem tsim siv lwm cov ntaub ntawv improvised uas tuaj yeem tau txais lub teeb liab. Qhov pheej yig tshaj piezo tuaj tos hauv khw muag khoom raug nqi txog 2000 rubles, thiab koj tus kheej cov nqi yog 100 feem ntau. Ntxiv mus, yog tias koj nkag siab txog hluav taws xob engineering ntawm theem pib, koj tuaj yeem xaiv txoj haujlwm zoo tshaj plaws rau kev txhim kho cov khoom thauj rau koj tus kheej kom lub suab sib haum. koj xav tau.
Kawm koj lub cuab yeej thiab nyiam suab paj nruag! Tsim kom muaj kev vam meej rau koj!
