Indlela yokwenza ikholomu ocingweni?

Amandla ifoni emuva Izipikha akubona bonke ulahlekile. Abantu abaningi bathanda ulalele umculo kakhulu loudly. Ukwandisa izinga umsindo kuyadingeka ukwenza amplifier ekhethekile.

Ngaphambi kokwenza ikholomu, kubalulekile ukuthola imininingwane edingekayo. Okokuqala, sithenga TDA2003 chip noma into efana nalokho kuso. Kungenjalo, ungase ukhethe K174UN14. capacitors Eminye uthenge of amakhono ehlukene: 10 MF (owodwa), 100 MF (ezimbili), 0.1 MF (owodwa), 470 MF (elilodwa). voltage yabo kumele okungenani ibe 16, volts Nokho, bavunyelwe ukusebenzisa ezinkulu capacitors ukucindezeleka, kodwa kulokhu, amandla ukusetshenziswa izokwenyuka.

Ngaphambi wenze ikholomu ngezandla zakho, kufanele ulungiselele resistors. Kuyodingeka ingqikithi ezintathu 10 Ohm 1 Ohm-1 Ohm. Yiqiniso, ungakhohlwa mayelana isikhulumi kanye solder ngensimbi nokunamathisela ngomthofu.

Uma zonke izinto uthenge, futhi emsebenzini ibhalwe, uqhubekele inhlangano. Kufanele kuqashelwe ukuthi njengoba-amplifier, ukhethe umfuziselo mono. Kunezizathu eziningana. Okokuqala, amplifier mono sisebenzisa amandla kancane kakhulu. Okwesibili, ngaphambi kokwenza kwekholomu ifoni ngezandla zakho, kumelwe uqaphele ngokucacile ukuthi kubalulekile ukuhlela ivolumu kangangokuthi kube eliphezulu kakhulu, futhi ibhethri anganikeza nekusebenta idivayisi isikhathi eside.

Isifunda amplifier kumele ihlolwe, akudingekile ukuthatha itholakale kuqala, njengoba kungenzeka kulimaze ifoni.

Lo mshini kungcono ukuqoqa ekhethekile ephrintiwe wesifunda ibhodi, uma amakhono ayo ukukhiqiza azitholakali, ungasebenzisa i amakhadibhodi abavamile. Ngaphambi ikholomu, uyibhala flat amakhadibhodi punctured imbobo ezingxenyeni benzelwe futhi axhunyiwe ndawonye izintambo mncane.

Lapho umhlangano usuphelile, kubalulekile ukuba ahlele kahle ukupholisa chip. Lokhu kungaba ezivamile aluminium uzimele noma ipuleti encane okuyinto nasezinsikeni izindlu ngomunye chip umshudo.

Umthombo Amandla kungenziwa kukhethwe amabhethri ezintathu ifoni, amandla ingqikithi okufanele kube kungekho kuka volts 11. isikhulumi eliphezulu enjalo-amplifier intando ukumelana 8 Ohm.

Indlela yokwenza ikholomu akho? Kunconywa ukuzama Dynamics of the imoto. 4-homny Analogue umculo kusukela uhlelo imoto UKUPHAYONA isebenza kahle futhi ukhiqiza umsindo emangalisayo.

NgoLwesine kutholakale isidumbu sendoda idivayisi kungenziwa lathathwa ikholomu ubudala, esetshenziselwa computer.

Sibheke indlela yokwenza ikholomu akho, kepha ngingenalo wathi into esemqoka: e lokhuni icala umsindo hhayi amuncwa umzimba, ngakho izinga sound. Kuzoba nokuzala imvamisa low, futhi umsindo akuyona ezingemnandi umsindo kugedlezela kanye nezingahlobene nendaba. Ngaphezu kwalokho, lokhu kunyakaza imvamisa high ukwakha oqinile, ngakho plastic nensimbi sebeqala ukwenza umsindo ngesikhathi umculo. ezimbalwa kakhulu abantu njengengelosi kwalokho ezinjalo.

izingxenye nokunamathisela ngomthofu akufanele imisiwe, ngeke kube izakhi phezu-Ukushisa, kungenjalo bayokudla sokudiliza ngokushesha futhi ujabulele imikhiqizo sizoba sifushane. Kubalulekile ukuthi ngesikhathi senqubo nokunamathisela ngomthofu emsebenzini nanoma yini enye.
