Isu tinogadzira synthesizer nemaoko edu

Synthesizer izvo zvinotengeswa muzvitoro zvehunyanzvi zvinowanzodhura zvakanyanya, uye mazhinji acho ane zvinhu zvisingadiwi nemunhu wese.

Kana iwe uchida kuchengetedza mari uye uchifarira zvemagetsi, unogona kuedza kugadzira kumba synthesizer nemaoko ako.

Nzira yekugadzira synthesizer nemaoko ako

Pane zvirongwa zvakawanda zvekugadzira a synthesizer - kubva kune yakapusa analogi kusvika kudhijitari. Nhasi iwe uchadzidza kugadzira polyphonic 48-kiyi synthesizer iwe pachako . Chishandiso, icho chichakurukurwa, chichavakwa pahwaro hwe4060 CMOS logic chip. Zvinokutendera kuti utambe chords uye zvinyorwa mu4 octave . Izvi zvinogona kuwanikwa kuburikidza nekushandisa gumi nemaviri majenareta ematoni gumi nemaviri uye makumi mana nemasere majenareta (rimwe kune rimwe nerimwe remakiyi makumi mana nemasere).

• Screwdriver Set;
• seti ye screws;
• screwdriver;
• perforator.

Kana zviri zvemidziyo, iwe unofanirwa kuve nehuwandu hwezvinhu zvinodikanwa uye zvikamu:

• se keyboard, unogona kushandisa makiyi kubva kune imwe synthesizer iyo isiri kurongeka, kana kuti kubva muchitoyi chomwana;
• bhodhi redunhu rakadhindwa (dielectric plate pane iyo matunhu emagetsi emagetsi aripo) yehukuru hwakakodzera;
• bhodhi rekiyi;
• seti yakakwana yewaya uye switch;
• iyo kesi inogona kugadzirwa kubva pamapurasitiki mapepa kana iwe unogona kutora zvikamu kubva kune asiri kushanda synthesizer a;
• 2 masipika;
• seti yezvinhu zvinodikanwa zveredhiyo uye microcircuits;
• amplifiers;
• kupinza kwekunze;
• magetsi 7805 (voltage stabilizer; yakanyanya ikozvino - 1.5 A, kubuda - 5 V; kupindira kwemagetsi - kusvika ku40 volts).
• dsP ICs (microcontrollers) iyo inokutendera kuti ushandise mamwe manzwi ekuwedzera.

Nhanho-ne-nhanho algorithm yezviito

1. Kuungana iyo synthesizer , iwe unofanirwa kuita nhevedzano yematanho anotevera:
2. Dhonza 12 maburi anokwira pamakiyi.
3. Gadzirira bhodhi rekibhodhi. Izvo zvinodikanwa kugadzira makiyi ega ega kiyi, zvichibva pahukuru hwavo, uye isa inoenderana microcircuits pabhodhi.
4. Gadzirira bhodhi redunhu rakadhindwa nekugadzirisa zvinhu zveredhiyo uye switch pairi.
5. Batanidza bhodhi rebhodhi, bhodhi redunhu rakadhindwa uye matauri maviri pasi pekasi, achibatanidza waya dzinodiwa kune zvinhu zvose.
6. Isa kiibhodhi.
7. Dhawunirodha gStrings app patablet yako kana smartphone. Zvinokutendera kuti utaure iyo synthesizer kune frequency chaiyo. Kubva pa synthesizer yakashongedzerwa ne frequency divider, inokwana kuridza chero chinyorwa chimwe, uye chasara chinozogadziriswa otomatiki.
8. Nzvimbo isina chinhu pakati pezvikamu inogona kugara dsP IC microcontrollers.
9. Gadzirisa chivharo chepamusoro.

Your synthesizer yagadzirira!

Matambudziko anogona kuitika uye nuances

Chenjerera kune zvinotevera zvakakosha pfungwa:

1. Mune shanduro yakaratidzwa, synthesizer a inoshandisa dunhu rine nhanhatu-yekuburitsa toni uye frequency kubva 130 kusvika 1975 Hz. Kana iwe uchida kushandisa mamwe makiyi uye octave, iwe unofanirwa kushandura huwandu hwematoni uye frequency.
2. Kune vanoda zviri nyore synth isina polyphony, iyo ISM7555 chip isarudzo yakanaka.
3. Pamavhoriyamu akaderera, iyo LM386 amplifier dzimwe nguva inogona kuburitsa kushomeka kushoma. Kuti udzivise izvi, unogona kuitsiva neimwe mhando ye stereo amplifier.

FAQ (mibvunzo inowanzo bvunzwa)

Ndingatenga kupi zvinhu zvinodikanwa zveredhiyo?

Dzinogona kutengwa kubva kuzvitoro zvakasiyana-siyana zvepamhepo, seAmpero electronics store.

Will matunhu kubva kuSoviet yekare synthesizer yakakodzera ?

Zvinhu zvekare zveredhiyo zvinoshandisika, asi mune iyi kesi, haufanirwe kuvimba neruzha rwemhando uye kugona kutamba chords .
