Scheme msindo elula odiyo. Indlela yokwenza msindo stereo izandla zakho

Eli nqaku liza kuthathwa isekethi ephilileyo msindo ukusetyenziswa ekhaya. Ngokuxhomekeka ekubeni, yintoni ndawo iya kusetyenziswa lo mshini (ekwabizwa ngokuba VLF - amandla njalo), kuya ube neempawu ezahlukeneyo nokuntsonkotha kwezikim yokwakha. Eli nqaku liza kuthi ngoko nangoko ichatshazelwa iintlobo ezintathu yokukhulisa - transistors, iitshiphusi kunye nezibane. Kwaye kufuneka uqale yokugqibela.

tube ULF

Ezi amaninzi zifumaneka izixhobo endala - kumabonwakude, kunomathotholo. Nangona iphelelwe, le nqubo usathandwa phakathi abathandi umculo. Kukho uluvo lokuba isandi ityhubhu icocekile kwaye intle ngaphezu "idijithali". Yinto enokwenzeka, kuyo nayiphi na imeko, isiphumo esifanayo evela izibane, musa ukusebenzisa leesekethe transistor. Kubalulekile ukuphawula ukuba wokukhulisa zeesekethe isandi (elula, esebenzisa ukukhanya) zinokuphunyezwa kwi transistor enye kuphela.

Kulo mzekelo, uphawu kufuneka kunikwa lombane tube kunomathotholo. Ukuya cathode inikezelwa ombane lisisiqalo - hlengiswe ngokulungisa uxhathiso kwisekethe. Le anode ngokusebenzisa capacitor kunye sombane zaseprayimari ngokubhijela ombane yonikezelo (150 V). Ngako oko, le yesibini kwemicimbi oludityaniswe isithethi. Kodwa eli cebo elula, kodwa mkhuba bavame usebenzise ezimbini okanye ibakala ezintathu uyilo, apho kukho msindo nezoviwo lokugqibela (on izibane ezinamandla).

Izinto eziluncedo nezingeloncedo ngamacebo isibane

Yintoni ethile kunokuba kwi ubuchwepheshe tube? Ngaphezu kokuba kuxeliwe ukuba ombane anode kufuneka volts ngaphezulu kwe-150. Ukongeza kule omnye kufuneka babe AC lombane 6.3 V ukuba amandla imisontwana eqaqambayo nezibane. Ngamanye amaxesha ufuna 12.6, njengoko izibane kunye ombane nemisontwana apho. Ngoko ke nesiphelo - esikhulu circuit unikezelo lwamandla, imfuneko yokusebenzisa abaguquli omkhulu.

Kodwa kukho iingenelo ezahlula isibane ukusuka ubuchule transistor: olulula yofakelo, uqinile, phantse akunakwenzeka ukuba phantsi yonke scheme. Ngaphandle ukuba kufuneka uyeke isibane ibhaluni ukuba makayiqhawule. Awukwazi uthi malunga transistor - amaqithiqithana eshushu ngelotha okanye static lula kutshabalalisa isakhiwo inguqu. Le ngxaki efanayo kunye neetshiphusi.

iziphaluka transistor

Ngentla apha umzobo transistors msindo odiyo. Njengoko ubona, kunzima - sebenzisa inani elikhulu amacandelo, nto leyo ebangela yonke le nkqubo isebenze. Kodwa ukuba ungumgqithi kubahlisela kumacandelo ezincinane, kuvela oko kunzima kangaka. Kwaye yonke le nkqubo isebenza ngendlela efanayo njengoko kuchaziwe ngentla apha triode cleaner. Enyanisweni, lo transistor semiconductor - akukho nto kodwa transistor.

Uyilo elilula - umntu circuit semiconductor omnye ogama isiseko sidla nangoko lombane ezintathu ukusuka unikezelo kunye ngokusebenzisa resistor yocingo akhabayo kunye eqhelekileyo kwakunye ukusuka kumthombo umqondiso. Kususwa uphawu kukhulu ukusuka umqokeleli. I ezingasentla umzekelo zeesekethe msindo odiyo (transistors nezakhiwo). Imsulwa lisusiwe.

IMicrochips

Kakhulu kwizinga mihla high wokukhulisa liya kuba phezu engenelela. Ngethamsanqa, ngomhla ukuba enkulu. I-audio wesekethe elula wokukhulisa kwiqhezu iqulethe inani elincinane kakhulu lweziqalelo. Kwaye yenza wena a elungileyo VLF angenza nawuphi na umntu onako ngaphezulu okanye nokunyamezeleka ngaphantsi ukuphatha i zentsimbi ngelotha. Njengoko umthetho, nj iqulethe eziliqela capacitors kunye resistors.

Zonke ezinye izinto eziyimfuneko ukuze yomsebenzi ziyafumaneka kwi njengekristale. Kodwa eyona nto ibalulekileyo - kukutya. Kuba abathile yoyilo kufuneka asebenzise izinto amandla vuvabyi. Amaxesha amaninzi iba ingxaki kuzo. Iitshiphusi, leyo ufuna unikezelo lwamandla, umzekelo, kunzima ukuyisebenzisa ukuba ukwenziwa wokukhulisa imoto.

"Gadgets" luncedo

Ekubeni baqalisa ukuthetha yokukhulisa kwi iitshiphusi, ngoko kubalulekile ukukhankanya ukuba ingasetyenziswa ZIVAKALA. Ingakumbi izixhobo ezifana zenziwa chip. Bathi ziqulathe onke amacandelo afunekayo iza kwenza kuphela ufakelo elichanekileyo zonke izixhobo.

Kwaye uya kukwazi ukwenza utshintsho umculo besandi. Okuhamba nale LED Linganisi ukuba ngeke nje elula, kodwa ezintle sound umhambisi. Kwaye ke kakhulu umdla kubalandeli somsindo imoto - kukuthi, Kakade ke, ubuchule ukudibanisa subwoofer. Kodwa kubalulekile nikela icandelo elahlukileyo, kuba umxholo umdla kwaye ulwazi.

Subwoofer - yinto nje

To connect i subwoofer (subwoofer) kufuneka wenze mono msindo eyahlukileyo. Ukuba ukhangela iisampulu yokukhulisa mveliso, ukuba kunokwenzeka ukuba yokukhulisa sestiriyo nesemono. Eyokuqala liqhagamshelene izithethi, kwaye eyesibini - ukuya subwoofer. Ngaphezu koko, le yesibini kukho inkalo encinane - ndawonye ibandla emnyango yecebo esezantsi-empumelelo. Kuxhomekeka kuhlobo ixabiso, le lokucoca ukulawulwa okanye hayi. Qokelela isandi ngezandla zakhe beesekethe wokukhulisa sisetyenziswe kwi engenelela banokuba ngemizuzu, njengoko akukho nto nzima ngayo.

Esilula filter yokupasa esezantsi - a resistors ezimbalwa kunye capacitors enxulumene kwisekethe eboniswe ngasentla. Ukwenza ngetyathanga onjalo umqondiso wokukhulisa osho a rhoqo ethile uluhlu 30-60 Hertz apha. Oku le rhoqo lo ziyanyuswa ze idluliselwe ULF woofer. Kufuneka kuqatshelwe ukuba icebo lokucoca igalelo eliphantsi-lokuphumelela kuyimfuneko ukubeka ulawulo umthamo.

Izinto eziluncedo yokukhulisa chips mihla

Emva kokuqwalasela zonke iintlobo yokukhulisa kunokwenzeka, sinokugqiba ukuba umgangatho ophezulu eyenziwe elula kuphela kwisiseko into mihla. A lot yeetships kuveza ukuba yokukhulisa frequency esezantsi. Ngokomzekelo ULF iTDA uhlobo kunye amanani reference ezahlukeneyo.

Zisetyenziswa phantse kuyo yonke indawo, ekubeni kukho zombini chips angamarhoqorhoqo, namandla. Umzekelo, ikhompyutha isithethi ephathwayo kungcono ukusebenzisa chip apho amandla ayikho ngaphezulu kwe 2-3 watts. Kodwa izixhobo izithuthi okanye nemisindo yeqonga ekhaya, kungakuhle ukuba usebenzise chip watts ngaphezulu kwama-30. Kodwa ingqalelo yokuba isidingo sokukhusela yokukhulisa amandla ephilileyo. Schemes kufuneka avotayo fuse leyo likhusela ngokuchaseneyo iziphaluka ezimfutshane kwikhonkco.

Plus kwakhona into yokuba ufuna unikezelo lwamandla omkhulu, ukuze lula ukusebenzisa esele zenziwe, umzekelo, ukusuka laptop, PC, MFP abadala (kwi entsha, njengoko umthetho, umbane ngaphakathi). Easy ukufaka - kuyinto ebaluleke kakhulu ekuqaleni bama. Ekuphela kwento efunekayo ukuze ezi zixhobo - kobubi esemgangathweni. Iicooler enye okanye ngaphezulu kwi radiator - Ukuba sithetha njengobuchule enamandla kuyimfuneko ukuseka esisinyanzelo.
