Senza i-synthesizer ngezandla zethu

Ama-synthesizers ezithengiswa ezitolo ezikhethekile ngokuvamile zibiza kakhulu, futhi eziningi zazo zinezici ezingadingeki wonke umuntu.

Uma ufuna ukonga imali futhi uthanda izinto zikagesi, ungazama ukwenza okwasekhaya i-synthesizer ngezandla zakho.

Indlela yokwenza i-synthesizer ngezandla zakho

Kunezinhlelo eziningi zokukhiqiza i-synthesizer - kusukela ku-analog elula kuya kweyedijithali. Namuhla uzofunda ukwenza i-polyphonic 48-key i-synthesizer wena . Idivayisi, okuzoxoxwa ngayo, izokwakhiwa ngesisekelo se-4060 CMOS logic chip. Izokuvumela ukuthi udlale izintambo kanye namanothi ku-4 octaves . Lokhu kungafezwa ngokusebenzisa amajeneretha angama-12 amathoni angu-12 namajeneretha ethoni angama-48 (owodwa ngokhiye ngamunye wama-48).

Okuzodingeka

• isethi yezinto ezidingekayo zomsakazo kanye nama-microcircuits;
• ama-amplifiers;
• okokufaka kwangaphandle;
• amandla kagesi 7805 (i-voltage stabilizer; esiphezulu samanje - 1.5 A, okukhiphayo - 5 V; isikhawu se-voltage yokufaka - kufika ku-40 volts).
• dsP Ama-IC (ama-microcontroller) akuvumela ukuthi usebenzise imithelela yomsindo eyengeziwe.

Isinyathelo ngesinyathelo i-algorithm yezenzo

1. Ukuhlangana i-synthesizer , udinga ukwenza uchungechunge lwezinyathelo ezilandelayo:
2. Gcoba izimbobo ezingu-12 okhiye.
3. Lungiselela ibhodi lekhibhodi. Kudingekile ukwenza izimpawu zokhiye ngamunye, ngokusekelwe ngobukhulu bawo, futhi ubeke ama-microcircuits ahambisanayo ebhodini.
4. Lungiselela ibhodi lesifunda eliphrintiwe ngokulungisa izakhi zomsakazo kanye nokushintsha kuwo.
5. Namathisela ibhodi lekhibhodi, ibhodi lesifunda eliphrintiwe kanye nezipikha ezimbili phansi kwekesi, ukuxhuma izintambo ezidingekayo kuzo zonke izakhi.
6. Faka ikhibhodi.
7. Landa uhlelo lokusebenza lwe-gStrings kuthebulethi yakho noma i-smartphone. Izokuvumela ukuthi ushune i-synthesizer kufrikhwensi efanele. Kusukela i i-synthesizer ifakwe i-frequency divider, kwanele ukushuna noma yiliphi inothi elilodwa, futhi okunye kuzoshunwa ngokuzenzakalelayo.
8. Isikhala esingenalutho phakathi kwezingxenye singabamba dsP Izilawuli ezincane ze-IC.
9. Lungisa ikhava ephezulu.

Your i-synthesizer ilungile!

Izinkinga ezingenzeka kanye nama-nuances

Naka amaphuzu abalulekile alandelayo:

1. Kunguqulo eyethulwe, i-synthesizer a isebenzisa isekethe enethoni yokuphuma eyisithupha kanye nemvamisa ukusuka ku-130 kuye ku-1975 Hz. Uma ufuna ukusebenzisa okhiye abaningi nama-octave, udinga ukushintsha inani lamathoni namafrikhwensi.
2. Kulabo abadinga elula i-synth ngaphandle kwe-polyphony, i-chip ye-ISM7555 iyindlela enhle.
3. Ngamavolumu aphansi, isikhulisi se-LM386 kwesinye isikhathi singakhiqiza ukuhlanekezela okuncane komsindo. Ukuze ugweme lokhu, ungafaka esikhundleni salo uhlobo oluthile lwe-stereo amplifier.

I-FAQ (imibuzo evame ukubuzwa)

Ngingazithenga kuphi izinto ezidingekayo zomsakazo?

Angathengwa ezitolo ezahlukahlukene eziku-inthanethi, njengesitolo se-Ampero electronics.

Izifunda ze-Will ezivela eSoviet endala ukulingana kwe-synthesizer ?

Izakhi zomsakazo ezindala ziyasebenziseka, kodwa kulokhu, akufanele uthembele kukhwalithi yomsindo enhle kanye nekhono lokudlala izintambo .
