Nyob zoo, music lovers thiab instrument enthusiasts! Raws li cov khoom lag luam graphite, kuv tau pom ua ntej yuav ua li cas cov ntaub ntawv zoo nkauj no tuaj yeem muaj kev cuam tshuam tiag tiag rau cov khoom siv suab paj nruag. Hauv qhov blog no, kuv yuav rhuav tshem cov khoom graphite li cas los ua si thaum nws los ua suab paj nruag zoo.
Cia peb pib nrog cov hauv paus. Graphite yog ib hom carbon uas paub txog nws cov khoom tshwj xeeb. Nws yog mos, nplua, thiab muaj hluav taws xob zoo heev thiab thermal conductivity. Tab sis dab tsi tiag tiag ua rau nws nthuav rau cov twj paj nruag yog nws qhov ceev thiab kev co yam ntxwv.
Ib txoj hauv kev tseem ceeb ntawm cov khoom lag luam graphite cuam tshuam rau acoustics yog los ntawm lawv siv hauv Graphite Box Bowls. Cov tais no feem ntau siv rau qee yam ntawm cov twj paj nruag percussion. Qhov ntom ntawm graphite plays lub luag haujlwm tseem ceeb ntawm no. Thaum ib tug percussionist ntaus lub ntsuas, lub graphite tais vibrates. Nws qhov ceev tso cai rau ib hom kev co qauv. Tsis zoo li lwm cov ntaub ntawv, graphite tuaj yeem tsim cov nplua nuj, suab nrov. Txoj kev nws vibrates kuj pab kom nthuav tawm lub suab sib npaug, muab qhov sib npaug thiab puv - lub cev acoustic.
Xav txog lub nruas. Yog tias koj yuav tsum siv lub thawv graphite lub tais ua ib feem ntawm lub nruas kev tsim kho, qhov kev tawm tsam thawj zaug yuav tsim kev vibrations uas taug kev los ntawm graphite. Cov kev vibrations no ces xa mus rau huab cua, tsim suab nthwv dej. Lub graphite lub peev xwm los tswj thiab tsim cov kev vibrations txhais tau hais tias lub nruas tuaj yeem tsim lub suab sib txawv. Nws yuav muaj qhov sib sib zog nqus, ntau dua resonant ntses bass thaj tsam piv rau lub nruas ua nrog cov khoom sib txawv. Qhov no yog vim graphite tuaj yeem ua rau qee qhov siab - zaus vibrations thaum txhim kho qhov tsawg - zaus, uas yog lub luag haujlwm rau cov nplua nuj, thumping suab peb nyiam hauv percussion.
Tam sim no, cia peb tham txog Graphite Moulds. Cov no yog siv rau hauv cov txheej txheem tsim khoom ntawm ntau yam khoom siv suab paj nruag. Thaum ua tej yam xws li lub caj dab guitar lossis violin pegs, siv graphite pwm tuaj yeem muaj kev cuam tshuam loj rau qhov kawg ntawm cov khoom siv acoustic.
Thaum lub sij hawm tsim cov txheej txheem, graphite pwm muab cov duab meej rau qhov. Tab sis nws kuj cuam tshuam nrog cov khoom raug molded. Piv txwv li, thaum molding lub caj dab guitar, graphite pwm tuaj yeem cuam tshuam li cas ntoo (los yog lwm yam khoom) teeb thiab hardens. Thaum tshav kub kub conductivity ntawm graphite los ua si ntawm no. Raws li cov khoom nyob rau hauv pwm txias, graphite pab nyob rau hauv ib tug ntau txawm tis ntawm tshav kub. Qhov no ua rau muaj ntau yam qauv ntawm lub caj dab guitar.
Lub qhov dej - lub caj dab guitar yog qhov tseem ceeb rau kev ua kom zoo nkauj. Nws cuam tshuam li cas cov hlua vibrate thiab hloov lawv lub zog rau lub cev ntawm lub guitar. Lub caj dab ua nrog kev pab los ntawm graphite pwm tuaj yeem ruaj khov dua, uas txhais tau hais tias tsis xav tau kev vibration tsawg dua. Cov hlua tuaj yeem vibrate ntau ywj siab, ua kom pom tseeb, ntau lub suab nrov. Thiab thaum nws los txog rau intonation, lub caj dab molded kom zoo tuaj yeem xyuas kom meej tias lub guitar nyob twj ywm zoo dua, ua rau tag nrho cov suab paj nruag ua tau zoo dua.
Lwm cov khoom uas tsim nyog hais txog yog Graphite Board. Graphite boards tuaj yeem siv ntau txoj hauv kev hauv cov twj paj nruag. Qee zaum, lawv tuaj yeem siv los ua lub suab - txhim kho cov khoom. Piv txwv li, nyob rau hauv ib lub twj paj nruag keyboard, lub graphite board tuaj yeem muab tso rau hauv qhov chaw muaj tswv yim kom nqus tau thiab hloov kev vibrations.
Lub graphite pawg thawj coj saib lub peev xwm los nqus cov vibrations pab txo qis suab nrov thiab resonance. Nws ua zoo li lub lim dej, cia tsuas yog qhov xav tau ntau zaus dhau los. Qhov no tuaj yeem ua rau lub suab tsim los ntawm cov cuab yeej keyboard ntxuav thiab tsom ntau dua. Lub redirected vibrations kuj tuaj yeem txhim kho qhov ntim tag nrho thiab qhov projection ntawm lub suab. Los ntawm kev tswj txoj kev vibrations mus, lub graphite board tuaj yeem ua rau lub suab nrov nrov thiab muaj zog dua yam tsis muaj kev cuam tshuam qhov tseeb.
Hauv cov cuab yeej cua, cov khoom graphite kuj tuaj yeem cuam tshuam. Piv txwv li, hauv qee lub qhov ncauj qhov ncauj, graphite tuaj yeem siv los txhim kho cov cua ntws thiab txoj hauv kev uas cov cua vibrates. Qhov saum npoo du ntawm graphite tso cai rau lub laminar airflow ntau dua, uas yog qhov tseem ceeb rau kev tsim lub suab meej thiab zoo ib yam. Thaum cov huab cua ntws zoo los ntawm lub qhov ncauj, nws tuaj yeem tsim kev vibrations ruaj khov hauv qhov ntsuas, ua rau lub suab zoo dua -.
Cia peb tsis txhob hnov qab txog qhov zoo nkauj thiab cov tswv yim zoo ib yam. Cov khoom siv graphite feem ntau siv tau ntev heev. Qhov no txhais tau hais tias cov twj paj nruag ua nrog cov khoom siv graphite tuaj yeem siv sijhawm ntev dua. Lub guitar nrog lub graphite - moulded caj dab los yog ib qho cuab yeej percussion nrog lub graphite lub thawv lub tais yog qhov yuav tiv taus qhov kev sim ntawm lub sij hawm thiab txuas ntxiv ua suab nrov. Thiab los ntawm qhov zoo nkauj ntawm qhov pom, graphite muaj qhov zoo nkauj, niaj hnub saib uas tuaj yeem ntxiv qhov kov ntawm style rau txhua qhov ntsuas.
Yog li, txawm tias koj yog ib tus kws tshaj lij tshuab raj tab tom nrhiav rau qhov ntxiv ntawm lub suab zoo lossis cov chaw tsim khoom tsim los tsim cov khoom siv suab paj nruag siab - kawg, cov khoom graphite yog qhov tsim nyog xav txog. Lawv muab kev sib xyaw ua ke ntawm cov txiaj ntsig acoustic, durability, thiab style.
Yog tias koj txaus siab tshawb nrhiav cov khoom lag luam graphite tuaj yeem txhim kho koj cov cuab yeej suab paj nruag, kuv xav nrog koj tham. Peb tuaj yeem sib tham txog koj cov kev xav tau tshwj xeeb thiab seb peb cov khoom siv graphite tuaj yeem ua raws li koj qhov yuav tsum tau ua. Cia li ncav tes, thiab cia peb pib ua ib co zoo - suab paj nruag ua ke!
