Electro-acoustic guitar: ntsuas muaj pes tsawg leeg, lub hauv paus ntsiab lus ntawm kev ua haujlwm, keeb kwm, siv

Bards, pop singers, jazzmen feem ntau coj theem nrog guitar hauv lawv txhais tes. Ib tug neeg uas yog uninitiated nyob rau hauv lub subtleties thiab peculiarities ntawm ua yeeb yam tswv yim tej zaum yuav xav hais tias qhov no yog dog dig acoustics, raws nraim tib yam li nyob rau hauv txhais tes ntawm cov txiv neej nyob rau hauv lub vaj los yog novice musicians. Tab sis qhov tseeb, cov neeg ua yeeb yam no ua si lub suab paj nruag tshaj lij hu ua electro-acoustic guitar.

Ntaus ntawv

Lub cev yog tib yam li classic acoustics - ntoo nrog wavy notches thiab ib puag ncig resonator qhov nyob rau hauv cov hlua. Lub caj dab yog tiaj tus rau sab ua haujlwm thiab xaus nrog lub taub hau nrog tuning pegs. Tus naj npawb ntawm cov hlua sib txawv ntawm 6 txog 12.

Qhov sib txawv nrog cov acoustic guitar nyob rau hauv cov qauv ntawm cov khoom muaj pes tsawg leeg, muaj cov khoom siv hluav taws xob uas muaj lub luag haujlwm rau kev hloov suab thiab suab zoo. Qhov sib txawv no tso cai rau koj los tsim lub suab meej ntawm lub acoustic guitar nrog lub suab nrov.

Ib qho piezo pickup nrog ib lub pickup yog ntsia hauv qab qhov pib hauv rooj plaub. Ib qho khoom siv zoo sib xws muaj nyob rau ntawm cov guitars hluav taws xob, tab sis nws ua haujlwm ntawm ntau zaus thiab tsuas yog siv rau cov twj paj nruag nrog cov hlua hlau.

Lub roj teeb ntim tau muab tso rau ze rau lub caj dab kom tus kws ntaus suab paj nruag tuaj yeem ua haujlwm ntawm theem uas tsis txuas nrog hluav taws xob. Lub timbral thaiv tsoo rau sab saum toj. Nws yog lub luag haujlwm rau kev tswj lub suab ntawm electroacoustics, tso cai rau koj los kho cov ntoo, nthuav cov peev txheej ntawm cov cuab yeej.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm

Hluav taws xob acoustic guitar yog ib tug tswv cuab ntawm cov hlua tsev neeg. Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog tib yam li ntawm acoustics - lub suab raug rho tawm los ntawm plucking cov hlua los yog ntaus lawv. Qhov kom zoo dua ntawm electroacoustics nyob rau hauv lub peev xwm txuas ntxiv ntawm qhov ntsuas. Nws tuaj yeem ua si yam tsis tau txuas nrog hluav taws xob, uas tsis tuaj yeem ua tau nrog lub guitar hluav taws xob. Hauv qhov no, lub suab yuav zoo ib yam nrog cov acoustics. Los yog los ntawm kev txuas mus rau lub tov khoom thiab lub microphone. Lub suab yuav dhau los ua ze rau hluav taws xob, nrov dua, juicier.

Thaum tus ntaus suab paj nruag pib ua si, cov hlua vibrate. Lub suab tsim los ntawm lawv dhau los ntawm piezo sensor ua rau hauv lub eeb. Nws tau txais los ntawm tus neeg nqa khoom thiab hloov mus rau hauv cov teeb liab hluav taws xob uas raug xa mus rau lub suab thaiv. Nyob ntawd lawv tau ua tiav thiab tso tawm los ntawm lub amplifier nrog lub suab meej. Muaj ntau hom electro-acoustic stringed instrument nrog ib daim ntawv teev cov khoom. Cov no tuaj yeem ua tau nyob rau hauv tuners, suab los, roj teeb tswj, preamplifiers nrog ntau hom suab tswj. Equalizers kuj tseem siv, muaj txog li rau rau qhov kev sib tw ntawm qhov xav tau frequencies.

Keebkwm tshwm sim

Thaum pib ntawm lub xyoo pua XNUMX tau raug cim los ntawm ntau qhov kev sim ntawm cov khoom siv hluav taws xob ntawm kev vibrations ntawm cov hlua ntsuas. Lawv tau ua raws li kev hloov pauv ntawm cov xov tooj transmitters thiab lawv cov kev siv hauv cov khoom tsim. Kev txhim kho tau kov cov banjo thiab violin. Cov kws ntaus suab paj nruag tau sim ua kom nrov nrov nrog kev pab ntawm lub laub khawm microphones. Lawv tau txuas nrog cov hlua khi, tab sis vim kev co, lub suab tau distorted.

Electro-acoustic guitar tau tshwm sim nyob rau hauv lub lig 30s ntev ua ntej cov tsos ntawm hluav taws xob guitar. Nws lub peev xwm tau txais txiaj ntsig tam sim ntawd los ntawm cov kws tshaj lij kws tshaj lij uas tsis muaj qhov ntim ntawm cov nkauj tsim tawm rau kev ua yeeb yam "nyob". Cov neeg tsim qauv pom qhov tseeb cov yam ntxwv los ntawm kev sim nrog lub microphones uas distorted lub suab thiab hloov lawv nrog electromagnetic sensors.

Cov lus pom zoo rau kev xaiv

Muaj ntau ntau hom hluav taws xob acoustic guitars. Rau cov pib tshiab, nws yog qhov zoo dua los pib kawm nrog cov pa 6-txoj hlua acoustic. Cov kws tshaj lij yog nyob ntawm lawv tus kheej nyiam, cov yam ntxwv ntawm kev siv, xav tau kev ua haujlwm ntawm theem lossis hauv chav kaw suab. Txhawm rau nkag siab yuav ua li cas xaiv lub guitar electro-acoustic, koj yuav tsum paub cov yam ntxwv ntawm nws cov cuab yeej. Lub ntsiab sib txawv yog nyob rau hauv lub teeb sensors. Lawv tuaj yeem yog:

• nquag - powered los ntawm roj teeb los yog kev cob cog rua los ntawm ib tug hluav taws xob qaum mus rau lub chaw taws teeb tswj;
• passive - tsis xav tau lub zog ntxiv, tab sis suab ntsiag to.

Rau kev ua yeeb yam, nws yog qhov zoo dua los yuav ib qho cuab yeej nrog lub piezoelectric pickup. Thaum xaiv, koj yuav tsum coj mus rau hauv tus account cov hom uas siv nyob rau hauv ntau hom:

• jumbo - siv nyob rau hauv "lub teb chaws", muaj suab nrov;
• dreadnought - txawv los ntawm qhov tseem ceeb ntawm cov zaus tsawg hauv cov ntoo, haum rau kev ua yeeb yam hauv ntau hom thiab solo;
• pej xeem - suab ntsiag to dreadnought;
• ovation - ua los ntawm cov khoom siv dag zog, tsim nyog rau kev ua yeeb yam;
• auditorium - sib txawv ntawm cov yam ntxwv zoo ntawm solo qhov chaw.

Kev ntseeg siab players tuaj yeem hloov mus rau 12-txoj hlua guitar. Nws yuav tsum tau kawm txog kev ua si tshwj xeeb, tab sis muaj suab zoo, nplua nuj.

siv

Electroacoustics yog ib qho cuab yeej siv rau kev siv thoob ntiaj teb. Nws tuaj yeem siv tau ob qho tib si thaum txuas nrog lub network, thiab tsis muaj nws. Qhov no yog qhov sib txawv tseem ceeb ntawm ib tug tswv cuab ntawm tsev neeg txoj hlua thiab ib qho hluav taws xob guitar, uas tsis tuaj yeem ua si yam tsis tau txuas nrog hluav taws xob tam sim no.

Electro-acoustic guitars tuaj yeem pom hauv tes Andrei Makarevich, Boris Grebenshchikov, frontman ntawm ChiZh thiab K band Sergei Chigrakov thiab Nautilus soloist Vyacheslav Butusov. Lawv tau masterfully muaj los ntawm cov hnub qub nyuaj pob zeb Kurt Cobain, Ritchie Blackmore, tsis txawj tuag Beatles. Jamens thiab pej xeem suab paj nruag ua yeeb yam poob rau hauv kev hlub nrog lub twj paj nruag, vim hais tias, tsis zoo li ib tug acoustic guitar, nws tso cai rau koj mus nyob twj ywm nyob ib ncig ntawm lub theem, tsim tsis tau tsuas yog suab paj nruag, tab sis kuj ib tug tag nrho-fledged yeeb yam.
