YoLungiso sesimangalo ngezandla zakho imizuzu eli-15

eyayithanda Wonke ekuqaleni engenazingcingo emva kokuba amalinge okuqala nempumelelo, uziva nobumnandi uloyiso bakhe, ufuna ukuzama ukwenza into ngoku. Hayi into yokudlala, kodwa ngokwenene ukusebenza into epheleleyo. Ukuze wenze oku, ngokugqibeleleyo ezifanelekileyo ekhaya ezilula msindo yoLungiso, nto leyo izandla onobuchule nga kuhlanganisana kwimizuzu nje embalwa.

I isicelo phi na? Okokuqala, injongo eyenzelwe yona, oko kukuthi, ukuze ikhulise umqondiso ovela ithoni okanye preamplifier, oko kukuthi apho uphawu audio ibuthathaka kakhulu, kwaye akunakwenzeka ukudibanisa headphones. Kulo mzekelo, ungenza msindo yoLungiso ngezandla zakho.

Okwesibini, kubalulekile njengesixhobo olongezelelweyo. Eziphathekayo yoLungiso sesimangalo kakhulu Akusebenzi uvavanyo kwiisekethe. Ngenxa rhoqo kukho imfuneko ukufumana indawo ukwaphula busebenze omtsha ukuba obuziqokelele, kodwa yena akafuni kusebenza. Umzekelo, nikwenzile yoLungiso msindo efanayo izandla zakho. Uya kunceda ekufuneni ezibangela nandzu. Nge kuyo, ungenza ngokukhawuleza kakhulu ukufumana indawo apho uphawu inyamalala. Kudla oku kwenzeka ngenxa makangakhohlisi: inxalenye kakubi soldered, capacitor olungachanekanga, njl Abangaboniyo okanye umvavanyi unobangela kunokuba nzima ukufumana.

Yenza msindo yoLungiso ngezandla zakho kuba nje yesekethe mono iqulathe amacandelo ezintlanu kuphela. Oku kusekelwe phezu TDA7050 chip, obiza 30-80 engange. Kodwa ndicinga ukuba iifama zakho amacandelo elektroniki, esoloko zifumaneka nakweyiphi ngehlombe kulo mzekelo, kukho chip enjalo. Lidla ngokusetyenziswa xa abadlali lomsindo nezinye isandi nokuzala izixhobo ezilula.

Kwi chip inye kwenziwa kunye stereo yoLungiso msindo ngezandla zakho. Kuya kufuneka ukuba ukongeza capacitor ezimbini polar kwiziphumo (ingaba omnye), kwaye igalelo ulawulo umthamo angenziwa ombaxa resistor variable.

chip kukodwa a mshini amandla kwi izindlu ubungakanani eqhelekileyo (DIP8). ombane Ukusebenza of volts 1.6 ukuya ku-6. Kubadle amandla amaninzi. amandla yemveliso kuxhomekeke ombane unikezelo. In lwalo stereo phantsi umthwalo ohms 32 kunye lombane volts ezintathu imveliso ufumana malunga 130 milliwatts etshaneli nganye. Xa lidibane kwisiphaluka kwebhulorho kwi lwalo umthamo mono kabini. Isiphumo yesekethe uyakhuseleka circuit elifutshane.

Idayagram enikwe kuMfanekiso 1. uphawu kokufaka isicelo zoku-1 no-3 head 32 ohms oxhulumene kwi ezinjengeetheminali 7 no 8. Ngokutsho iinkcukacha ikwimo kuvaleka, umthwalo kufuneka ungabi ohms ngaphantsi kwe-32. Lungisani unikezelo ombane uqhagamshele capacitors ibhasi C1 no-C2, 100, yaye 0.1 microfarads, ngokulandelelana. Resistor R1 - 22 ohms. Kaloku, mhlawumbi, nayo yonke inkcazelo womzekelo wethu wokuqala.

Iskim lwesibini Figure 3 isoloko isetyenziswa kwizixhobo prefabrication amancinci-ubungakanani. Ukuze kube kancinane ngakumbi nzima. Le nkqubo ibonisa zonke iinkcukacha eziyimfuneko. Isazobe 2 - inkqubo efanayo ukudibanisa abantetho isisiXhosa. Njengoko ubona, umahluko mncinane. Umphathi wesekethe ukuba izithethi capacitors polar asetyenziswe channel imveliso nganye, kwaye imo - emi capacitor eqhelekileyo kwi kwindawo uqhagamshelwano kumphathi wesekethe ngokugcina kwabo.
