Key systems
Tsuas muaj plaub ntawm lawv hauv lub tshuab ntaus piano.
- Sonic. Nws yog txoj hlua txoj hlua thiab daim thaiv npog uas tsim kom muaj suab nrov.
- Percussion keyboard. Nws suav nrog cov khoom siv tshuab thiab cov keyboard.
- Pedal. Tsim los ntawm ob lub ntsiab lus (pedals). Ib qho ua kom nrov nrov, thiab qhov thib ob ua rau lub suab tsis muaj zog. Qee cov qauv muaj peb lub pedals.
- Cas.
Nws nyuaj rau xav txog lub tshuab ntaus piano sab nraud yam tsis muaj lawv. Lawv txhawb nqa nws lub zog thiab kev ua siab ntev.
Sab nraub qaum ntawm rooj plaub yog tsim los ntawm ib lub thav duab ntoo, uas yog lub zog muaj zog. Hauv qee qhov kev hloov kho, futor nruab nrog spacers tuaj yeem npaj. Ua tsaug rau nws, lub cuab yeej muaj zog.
Tus futor muaj qhov dav dua. Nws nyob thoob plaws lub piano. Virbelbank koom nrog nws. Nws yog ib lub rooj tsavxwm tuab heev nrog ntau txheej. Rau kev tsim khoom, beech lossis maple yog siv.
Nkauj peg tau tsav mus rau nws ncab txoj hlua.
Boost deck
Los ntawm sab pem hauv ntej, lub lawj tshwj xeeb yog glued rau footor nrog nws cov npoo los tsim kom muaj suab nrov. Nws yog cov ntaub thaiv npog nrog qhov ntom ntawm 1 cm. Nws yog tsim los ntawm ob peb lub rooj sib dhos ua ke.
Cov kab yog nplaum rau sab nraum qab ntawm lub lawj. Lawv qhov chaw nyob rau hauv relation mus ntoo fibers yog perpendicular. Lawv cov khoom yog high quality spruce. Lawv kuj hu ua rips. Lawv ua kom lub suab nrov zog.
Cast hlau ncej. Cov hlua thiab pegs
Nws tau ruaj khov rau saum lub lawj uas tau teev tseg rau ntawm nws sab sab thiab mus rau footor. Hom fasteners - loj heev screws. Cov hlua khi rau ntawm nws.
Qhov ntsuas no siv txoj hlua hla txoj hlua. Nws muaj qhov tshwj xeeb hauv qab no ntawm txoj haujlwm thiab kev taw qhia ntawm cov hlua:
- bass ntsiab lus raws kab diagonally ntawm ib lub cev ces kaum mus rau lwm qhov: ntawm sab laug mus rau hauv qab txoj cai;
- cov ntsiab lus ntawm nruab nrab spectrum yog nyob rau hauv nqe lus 1 thiab mus rau hauv qab sab laug ces kaum.
Nyob rau hauv qab ntawm lub piano ntaus ntawv, cov hlua yog ob-kho ntawm ib sab ntawm cov pins ua rau hauv pegs (qhov uas coj lub impulses rau cov hlua).
Thiab qhov nro ntawm cov hlua, qhov nruj dua lawv haum rau qhov nyob.
Ntawm lawv qhov kawglub voj. Lawv txuas nrog rau cov pins rear mounted rau hauv qab ntawm tus ncej.
Keyboard thiab damper technology
Muaj ib lub rooj tshwj xeeb nyob rau pem hauv ntej ntawm rooj plaub. Nws hu ua shtulrama. Nws muaj ib tug piano key ntaus ntawv. Sab nraud consoles txhawb qhov kev teeb tsa no.
Damper thev naus laus zis txuas rau rauj qhov kev ua haujlwm thiab txuas rau ntawm ib lub txaj.
Pedal qauv
Nws suav nrog cov hauv qab no.
- Tus pedals lawv tus kheej.
- Tsugi.
- Stocks.
- Txhim kho cov ntsia hlau.
Raws li twb tau sau tseg lawm, muaj cov qauv nrog 2 lossis 3 pedals. Thawj muaj txoj cai thiab sab laug. Qhov thib ob, lawv tau ua tiav los ntawm lub hauv paus tivthaiv.
Thaum koj nias lub ntsiab lus, txhua tus mufflers synchronously sawv, thiab muaj chaw rau cov hlua. Nws hloov tawm lub suab txuas ntxiv - legato.
Yog tias koj nias rau sab laug, lub kauj tsheb kauj vab txav mus. Nws hloov tag nrho cov rauj rau cov hlua. Thiab muaj qhov sib txawv me ntsis ntawm lawv. Lub amplitude ntawm cov hammers ua me, thiab lawv cov tshuab kuj tsis muaj zog. Raws li qhov tshwm sim, lub ntsuas suab nrov dua.
Nyob hauv cov qauv nrog peb, lub hauv paus pedal, tus neeg saib xyuas tau qhib (ib lub bar tshwj xeeb nrog lub gasket, cim nrog tsab ntawv "M" hauv daim duab).
Thaum nias, levers tau qhib. Thiab cov hammers raug txwv los ntawm cov hlua: nruab nrab ntawm lawv muaj ib lub bar nrog ib tug mos mos strip. Nyob rau hauv no piano mechanics, cov hammers tua cov hlua los ntawm no plug. Thiabces lub suab tsis muaj zog heev.
Case parts
Los ntawm sab xub ntiag nws raug kaw los ntawm ob lub vaj huam sib luag. Ib qho yog hauv qab cov keyboard. Qhov thib ob yog saum nws.
Cov yuam sij raug them los ntawm lub zog muaj zog tso rau hauv cov kab noj hniav ntawm cov phab ntsa sab. Lub folding valve yog mounted rau nws nrog kev pab los ntawm hinges, mus rau sab hauv uas ib tug music sawv yog txuas.
Cov ntaub ntawv saum toj kawg nkaus yog mounted ntawm zawv zawg hinges. Thaum lub sijhawm ua si, nws raug tso cai qhib nws kom lub suab nce me ntsis.
Lub log yog txuas rau hauv qab ntawm lub cev. Qhov no yog ib qho kev ntsuas kom yooj yim txav ntawm qhov ntsuas hauv chav.

Cov kab ke siv feem ntau hauv lub piano muaj qis dua dampers. Nws lub ntsiab tivthaiv yog lub ntsiab transverse beam. Cov tshuaj ntsiav hauv qab no tau nruab rau ntawm nws:
- cheat;
- daim levers hauv qab;
- damper retainers.
Tseem muaj cov squares thiab ib tug pas nrig tshwj xeeb. Ua tsaug rau lawv, txhua tus mufflers ib txhij sawv ntawm cov hlua. Qhov no tshwm sim thaum koj nias lub pedal txoj cai.
Hmoob cuab tam
Yog tsis muaj nws, cov qauv sab hauv ntawm lub piano ua tsis tau. Nyob rau hauv lem, nws muaj:
- shulter (pav thaiv uas nws yog mounted);
-hammerstyle (bearing rod);
- taub hau;
- caij nplooj ntoos hlav rov qab rau rauj;
- xav;
-capsule;
- pas nrig ntxiv;
- pem hauv ntej schulter.
Cov ntsiab lus ntawm kev ua haujlwm
Lub kaw lus nrog cov mufflers qis dua muaj caj npab qis (daim duab). Nws wiggles nyob rau hauv lub capsule. Nws muaj ib feem protruding nyob rau hauv qab. Nws yog thawb los ntawm tus tsav lub taub hau (adjustable ntsia liaj qhov rooj) mounted rau nram qab kawg ntawm tus yuam sij.
Nyob rau sab saum toj ntawm lub zog yog nruab nrog primer uas tus pin (shulter pusher) txav tau yooj yim. Lub caij nplooj ntoos hlav thawb nws mus.
Nyob rau hauv hom zoo li qub, nws sab saud ua raws qhov kawg, upholstered hauv tawv.
Yog tias koj nias ib qho tseem ceeb, lub zog nce hauv tandem nrog tus pin. Nws thawb lub shulter. Thiab lub taub hau rauj, txav mus rau hauv arc, tawm tsam cov hlua.
Vim tias cov kev txav mus tom ntej no, lub ntsiab lus sab saud ntawm lub spire deviates thiab tawm hauv qab lub schulter.
rauj thaws tawm txoj hlua. Lub counterfenger (cov khau tshwj xeeb) yog tsau nrog lub fenger qhov tsis. Nyob rau hauv parallel, lub damper diav deflects tus coj lever. Raws li qhov tshwm sim, tus muffler txav deb ntawm cov hlua, thiab lawv tau txais chav rau suab.
Yog tias koj tso tus yuam sij, lub zog qis dua hauv duet nrog tus pin thiab nkag mus rau hauv qab lub shulter. Thaum lub sij hawm no, ib tug pas nrig mounted rau pem hauv ntej kawg ntawm lub lever rub nws thiab rauj rov qab. Yog li ntawd lub rauj sai sai thiab tag nrho rov qab mus rau qhov chaw nyob ntsiag to. Nyob rau hauv parallel, lub hammerstil nyob rau ntawm qhov chaw mos ntawm lub nqaj txhawb nqa. Lub sijhawm no, lub caij nplooj ntoos hlav depresses lub muffler, thiab nws tsom rau cov hlua. Thiab lawv qhov kev tsis txaus siab nres.
Digital Piano
Hnub no nws muaj koob meej loj vim nws txoj haujlwm. Tsis tas li ntawd, nws yog qhov sib dua ntau dua li nws cov classic counterpart ntawm qhov hnyav.
Nyob rau hauv lub cuab yeej ntawm lub piano digital tsis muaj qhov ntau ntawm subtleties ntawm lub tshuab. Lub suab yog tsim ua tsaug rau ib tug tshwj xeeb Circuit Court.
Cov keyboard ntawm no yog nruab nrog rauj qhov system. Qhov tshwj xeeb yog nyob ntawm qhov zoo ntawm cov yuam sij. Thiab thaum lub sij hawm qhov kev ua si, tus neeg ua yeeb yam xav tias qhov rov qab los ntawm kev ntaus ntawm rauj ntawm cov hlua. Txawm hais tias cov khoom no tsis nyob hauv lub cuab yeej. Qhov no yog qhov cuam tshuam rau lub suab zoo dua.
