Yuav ua li cas xaiv lub piano digital rau tus menyuam? Suab.
Lub piano digital yeej nws qhov chaw nyob hauv lub hnub tom qab kev sim hauv xyoo 1984, thaum 500 tus kws tshaj lij thiab cov neeg zoo tib yam tsis tuaj yeem paub qhov txawv ntawm lub suab piano zoo nkauj ntawm Ray Kurzweil's digital piano. Txij thaum ntawd los, kev sib tw ntawm "acoustics" thiab "tus lej" ntawm lub suab tau pib. “Casio” txawm tua promo yeeb yaj duab nyob rau hauv no vein:
Cov suab digital tsis yog tsim los ntawm cov hlua, tab sis los ntawm kev sib xyaw ua ke ntawm ntau qhov tsis sib xws, txhua qhov cuam tshuam rau qhov zoo. Cov kev sib txawv ntawm qhov tsis sib xws tsim ntau yam ntawm cov qauv piano digital uas koj ob lub qhov muag khiav dav! Txhawm rau taw qhia peb tus kheej, cia peb saib ntawm "hauv paus".
xeem lub sij hawm peb tham txog li cas cov lag luam yuav tsum , hnub no - yuav ua li cas lub suab yuav tsum. Thiab thawj yam uas yuav tsum to taub: yuav ua li cas nws yog tsim nyob rau hauv ib tug digital piano.
Ntu II. Peb xaiv lub suab.
Nyob rau hauv ib tug acoustic piano, qhov no yog ua li no: ib tug rauj ntaus ib los yog ntau tshaj stretched hlua, txoj hlua vibrates - thiab suab tau txais. Lub piano digital tsis muaj cov hlua, thiab lub suab raug ntaus los ntawm kaw kuaj .

Ib qho piv txwv yog ib qho me me digitized suab tawg. Lub suab ntawm cov twj paj nruag acoustic (piv txwv li, Steinway piano, timpani, flute, thiab lwm yam) feem ntau ua raws li cov qauv, tab sis kuj yog lub suab ntawm cov twj paj nruag hluav taws xob.

nplua nuj ntawm suab
Lub zog ntawm lub suab tsis nyob ntawm lub zog thiab ceev uas qhov kev sib cuag hauv lub piano kaw. Txhua yam yooj yim nyob ntawd: kev sib cuag raug kaw - muaj suab, nws tsis raug kaw - tsis muaj suab. Lub suab yeej ib txwm zoo ib yam. Yog li ntawd, txhawm rau nthuav tawm qhov sib txawv, lub suab ( kuaj ) hauv cov khoom siv digital raug kaw hauv txheej. Ib txheej yog lub suab ntsiag to rau kev ua si "piano", lwm qhov yog nruab nrab, ib feem peb yog nrov rau kev ua si "forte". Tsis tas li ntawd nyob rau hauv acoustic piano, lub suab tsim los ntawm ib tug rauj yog ntau nplua nuj dua yog hais tias peb cia li ntaus txoj hlua. Lub rauj tsis yog ib txwm ntaus ib txoj hlua xwb, lub suab yog reflected, nkag mus rau hauv resonance nrog rau lwm cov hlua, thiab lwm yam. Qhov tshwm sim yog lub suab nplua nuj ua los ntawm cov khoom sib txawv.
Tag nrho cov suab ntxiv no kuj raug kaw cais. Lub rhiab heev ntawm cov keyboard yog lub luag haujlwm rau lawv cov kev tsim tawm ntawm cov khoom siv hluav taws xob, thiab polyphony at qib acoustic.

Polyphony yog lub peev xwm ntawm lub processor rau tib lub sijhawm tsim cov suab tsis zoo uas txiav txim siab qhov zoo thiab qhov zoo ntawm qhov ntsuas lub suab.

Txhawm rau xa tag nrho cov suab ntau hauv cov pianos, thaum koj nias ib qho tseem ceeb, los ntawm 4 mus rau 16 cov ntawv sau polyphonic raug siv. Yog li ntawd, qhov loj dua qhov tshaj tawm polyphony (64, 128, 256…), lub suab zoo dua thiab zoo dua qub. Piv txwv li, tsim nyog xaiv nyob rau hauv cov nqe lus ntawm polyphony thiab pheej yig tus nqi yog Yamaha YDP-143R piano ( polyphony 128) thiab Yamaha CLP-525B ( polyphony 256):
Thaum xaiv, raug coj los ntawm qhov ntsuas no: yog tias koj xav tau qhov kev xaiv ze tshaj plaws rau acoustics, siv 256, yog tias koj siv ob peb xyoos los kawm lossis piano tsis yog lub ntsiab lus tseem ceeb hauv tsev kawm suab paj nruag, ces 128 yuav txaus.
hais lus
Txij li lub ntsuas hluav taws xob yog hluav taws xob, lub suab raug ntaus los ntawm cov neeg hais lus. Thiab thaum xaiv ib qho cuab yeej, koj yuav tsum tau ua haujlwm nrog cov qauv zoo ib yam li thaum xaiv qhov zoo acoustic system. Thiab ntawm no lub cev plays lub luag hauj lwm txiav txim siab. Cov neeg hais lus muaj zog teeb tsa cov cuab yeej nrog lub cev loj. Hauv Ntxiv rau , phab ntsa tom qab yuav muab lub suab bass thaj tsam. Ib qho kaj ntim yog ib qho piv txwv - Kurzweil CUP-2 BP :
Tab sis rau kev xyaum hauv tsev, ib qho kev xaiv yooj yim dua kuj tsim nyog. Ib phab ntsa nrog ib lub qhov yuav muab cov ntses bass thaj tsam tsawg, tab sis cov zaus siab thiab nruab nrab yuav hnov zoo dua. Ib qho piv txwv zoo yog Kurzweil CUP 220SR :
Thiab lub piano hauv rooj plaub yas muaj lub suab yooj yim heev, tab sis nws tuaj yeem nqa nrog koj los yog muab tso tseg tom qab lub txee yog tias koj npaj yuav ua si qee zaus. Ib qho piv txwv classic yog CASIO CDP-230R BK:
Yog xav paub ntxiv txog qhov twg thiab yuav ua li cas rau nruab cov neeg hais lus ntawm Roland digital pianos, saib cov yeeb yaj kiab:
