Peb ua ib tug synthesizer nrog peb tus kheej tes

Synthesizers uas muag hauv khw tshwj xeeb feem ntau kim heev, thiab ntau ntawm lawv muaj cov yam ntxwv uas tsis yog txhua tus xav tau.

Yog tias koj xav txuag nyiaj thiab nyiam cov khoom siv hluav taws xob, koj tuaj yeem sim ua lub tsev hluavtaws nrog koj tus kheej tes.

Yuav ua li cas ua ib tug synthesizer nrog koj tus kheej tes

Muaj ntau cov txheej txheem rau kev tsim khoom ib tug synthesizer - los ntawm qhov yooj yim tshaj plaws analog rau digital. Niaj hnub no koj yuav kawm yuav ua li cas ua ib tug polyphonic 48-key hluavtaws koj tus kheej. Cov cuab yeej, uas yuav tau tham txog, yuav tsim los ntawm 4060 CMOS logic nti. Nws yuav cia koj ua si chords thiab sau ntawv hauv 4 octaves . Qhov no tuaj yeem ua tiav los ntawm kev siv 12 zaus tshuab hluav taws xob rau 12 lub suab nrov thiab 48 lub suab nrov (ib qho rau txhua tus ntawm 48 tus yuam sij).

Dab tsi yuav xav tau

Raws li rau cov ntaub ntawv, koj yuav tsum muaj ib tug xov tooj ntawm cov khoom tsim nyog thiab qhov chaw:

• Raws li cov keyboard, koj tuaj yeem siv cov yuam sij los ntawm lwm tus hluavtaws uas yog tawm ntawm kev txiav txim, los yog los ntawm tus me nyuam cov khoom ua si;
• ib daim ntawv luam tawm Circuit Board (ib lub phaj dielectric uas lub circuits ntawm ib qho hluav taws xob Circuit Court nyob) ntawm qhov loj me;
• board rau cov yuam sij;
• tag nrho cov xov hlau thiab keyboards;
• rooj plaub tuaj yeem ua los ntawm cov ntawv yas lossis koj tuaj yeem nqa cov khoom los ntawm qhov tsis ua haujlwm hluavtaws a;
• 2 lub suab hais lus;
• ib txheej ntawm cov xov tooj cua tsim nyog thiab microcircuits;
• amplifiers;
• cov tswv yim sab nraud;
• Fais fab mov 7805 (voltage stabilizer; siab tshaj tam sim no - 1.5 A, tso zis - 5 V; input voltage ncua - mus txog 40 volts).
• dsP kev ICs (microcontrollers) uas tso cai rau koj siv cov suab nrov ntxiv.

Cov npe ntawm cov xov tooj cua

Ua tiav cov khoom tsim nyog hauv xov tooj cua:

Scheme ib . Qhov no suav nrog cov hauv qab no:

• 4060N nti (IC1-IC6) - 6 pcs.;
• Rectifier diode 1N4148 (D4-D39) - 36 pcs.;
• capacitor 0.01 uF (C1-C12) - 12 pcs.;
• resistor 10 kOhm (R1, R4, R7, R10, R 13, R16) - 6 pcs.;
• trimmer resistor 10 kOhm (R2, R5, R8, R11, R14, R17) - 6 pcs.;
• resistor 100 kΩ (R3, R6, R9, R12, R15, R18) - 6 pcs.

Scheme thib ob . _ Cov khoom yuav tsum tau muaj:

• linear regulator LM7805 (IC 1) - 1 pc.;
• Rectifier diode 1N4148 (D1-D4) - 4 pcs.
• capacitor 0.1 uF (C1) - 1 pc;
• electrolytic capacitor 470 uF (C2) - 1 pc.;
• electrolytic capacitor 220 uF (C3) - 1 pc.;
• resistor 330 Ohm (R1) - 1 pc.

Tswv yim peb . Nws suav nrog:

• Lub suab amplifier LM386 (IC1) - 1 pc.;
• capacitor 0.1 uF (C2) - 1 pc.;
• capacitor 0.05 uF (C1) - 1 pc.;
• electrolytic capacitor 10 uF (C4, C6) - 2 pcs.;
• resistor 10 Ohm (R1) - 1 pc.

Step-by-step algorithm ntawm kev ua

1. Sib sau ua ke lub synthesizer , koj yuav tsum tau ua ib tug series ntawm cov kauj ruam hauv qab no:
2. Laum 12 qhov mounting qhov ntawm cov yuam sij.
3. Npaj lub rooj tsavxwm rau cov keyboard. Nws yog ib qho tsim nyog los ua cov cim rau txhua tus yuam sij, raws li lawv qhov loj me, thiab tso cov microcircuits sib raug rau ntawm lub rooj tsavxwm.
4. Npaj lub rooj tsav xwm luam tawm los ntawm kev kho cov xov tooj cua thiab cov keyboards ntawm nws.
5. Txuas lub rooj tsavxwm keyboard, lub rooj tsavxwm luam tawm thiab ob tus neeg hais lus rau hauv qab ntawm rooj plaub, txuas cov xov hlau uas tsim nyog rau txhua lub ntsiab lus.
6. Nruab cov keyboard.
7. Rub tawm gStrings app rau koj lub ntsiav tshuaj lossis smartphone. Nws yuav tso cai rau koj mloog lub synthesizer mus rau qhov tseeb zaus. Txij li thaum hluavtaws yog nruab nrog ib tug zaus divider, nws yog txaus mus qhib ib qho kev ceeb toom, thiab tus so yuav tsum tau tuned.
8. Qhov chaw khoob ntawm qhov chaw tuaj yeem haum dsP kev IC microcontrollers.
9. Kho lub hau npog.

koj hluavtaws npaj tau txhij!

Tej teeb meem thiab nuances

Ua tib zoo mloog cov ntsiab lus tseem ceeb hauv qab no:

1. Nyob rau hauv qhov nthuav version, hluavtaws ib tug siv ib lub voj voog nrog rau lub suab tawm suab thiab zaus ntawm 130 txog 1975 Hz. Yog tias koj xav siv ntau tus yuam sij thiab octaves, koj yuav tsum tau hloov cov suab nrov thiab zaus.
2. Rau cov neeg xav tau ib qho yooj yim synth tsis muaj polyphony, ISM7555 nti yog qhov kev xaiv zoo.
3. Ntawm qhov ntim tsawg, LM386 amplifier tej zaum yuav ua rau me ntsis suab distortion. Txhawm rau zam qhov no, koj tuaj yeem hloov nws nrog qee hom stereo amplifier.

FAQ (cov lus nquag nug)
