Ucingo lwesipika ludlala indima ebalulekileyo kumgangatho wesandi sayo nayiphi na inkqubo yesandi, kodwa ihlala ingahoywa. Esi sikhokelo siya kutyhila iimfihlakalo zocingo lwesithethi, sichaza umsebenzi walo, iingenelo, kunye nendlela yokuwukhetha kunye nokusetyenziswa ngokufanelekileyo. Nokuba useka ithiyetha yasekhaya okanye inkqubo ye-stereo elula, ukuqonda ucingo lwesithethi ngundoqo ekuphumezeni esona sandi sibalaseleyo.

Yintoni ucingo lwesipika?
Ucingo lweSithethi luyindlela yokuphila yaso nasiphi na isixokelelwano somsindo, ukudibanisa i-amplifiers okanye abamkeli kwizithethi, ezivumela imiqondiso yombane ukuba idlule kwaye ivelise isandi. Ingaphezulu kwentambo nje; licandelo elibalulekileyo elinokuchaphazela kakhulu umgangatho wesandi. Ngokuqhelekileyo, iqulethe i-copper ezimbini ezifakwe kwi-insulated okanye i-aluminium conductors, kunye nobhedu yinto ekhethwayo ngenxa ye-conductivity ephezulu kunye nokuqina.
Igeyiji (ukutyeba) kocingo ngumba obalulekileyo, onamanani asezantsi abonisa iingcingo ezityebileyo. Iingcingo ezityebileyo zinokuthwala umgama omde kwaye zikhethwa kwimigama emide ukunciphisa ukulahleka komqondiso. I-insulation material idlala indima ekukhuseleni ucingo kumonakalo womzimba kunye nokuphazamiseka kwe-electromagnetic, ukuqinisekisa ukuhanjiswa kwesignali ecocekileyo.
Ukuqonda ulwakhiwo olusisiseko kunye neempawu zocingo lwesithethi kubalulekile kuye nawuphi na umthandi womsindo. Ayisiyonto nje yokudibanisa amacandelo; imalunga nokuqinisekisa imfezeko yesiginali yesandi ukusuka kumthombo ukuya kwisithethi, echaphazela yonke into ukusuka ekucaceni ukuya kubunzulu besandi.
Ingaba ucingo lwesipika lusebenza njani?
Iingcingo zesithethi zisebenza njengebhulorho yemiqondiso yomsindo, ukuhambisa impembelelo yombane ukusuka kwi-amplifier ukuya kwizithethi. Umgaqo ongundoqo ulula: njengoko iamplifier ivelisa umqondiso wesandi, ucingo lwesithethi luthwala olu phawu lusiya kwizithethi, apho luthi luguqulwe lube ngamaza omsindo esinokuwava. Ukusebenza kakuhle kunye nomgangatho wokudluliselwa komqondiso kuphenjelelwa yimathiriyeli yocingo, igeyiji kunye nobude.
Ukuxhathisa kombane kocingo yinto ebalulekileyo. Ukuchasana okusezantsi kuthetha ukuhanjiswa komqondiso okusebenzayo ngakumbi, kubaluleke kakhulu kumgama omde. Yiyo loo nto iingcingo ezishinyeneyo (amanani egeyiji esezantsi) zicetyiswa ukuba ziqhube ixesha elide, njengoko zinoxhathiso oluncinci kuneengcingo ezibhityileyo. Ukuchasana kunokunciphisa umqondiso, okukhokelela ekulahlekelweni kokuthembeka kunye nesandi esibuthathaka.
Ukongezelela, i-capacitance yocingo kunye ne-inductance inokuchaphazela umgangatho wesandi ngokuguqula isignali ngeendlela ezifihlakeleyo, ngakumbi kwiifrikhwensi eziphezulu. Umgangatho ophezulu wefowuni yesithethi yenzelwe ukunciphisa ezi ziphumo, ukuqinisekisa ukuba isignali efikelela kwizithethi isondele kwi-original kangangoko kunokwenzeka. Oku kuqinisekisa ukuveliswa kwesandi esicacileyo, esichanekileyo.
Iinzuzo kunye neengxaki zocingo lwesithethi
Ucingo lweSithethi lubonelela ngeenzuzo ezininzi, kubandakanya ukuphuculwa komgangatho wesandi, ukuguquguquka kwindawo yokubeka isithethi, kunye nokukwazi ukwenza inkqubo yakho yeaudio ngokwendlela oyithandayo. Ingcingo yesithethi ekumgangatho ophezulu inokunciphisa ilahleko yomqondiso kunye nokuphazamiseka, okukhokelela kwisandi esicacileyo, esinamandla ngakumbi. Oku kuphawuleka ngakumbi kwiinkqubo ezinamacandelo akumgangatho ophezulu, apho iinuances kwiaudio zinokuqondwa ngokulula ngakumbi.
Nangona kunjalo, kukwakho nezinye iingxaki ekufuneka ziqwalaselwe. Iingcingo zesithethi ezikwizinga eliphezulu zinokubiza, ngakumbi kwiiseto ezinkulu ezifuna ubude obude bentambo. Ukongezelela, ukungafani komgangatho wesandi phakathi koluhlu oluphakathi kunye neengcingo zesithethi eziphezulu zinokuba zibuqili kwaye zingenakuthethelela iindleko zabaphulaphuli abaqhelekileyo. Ukufakela kunokuba nzima ngakumbi, kufuna ukuqwalaselwa ngononophelo kwegeyiji yocingo, ubude, kunye nendlela ukuphepha ukuphazamiseka kunye nokufezekisa isandi esisiso.
Enye ingqwalasela yimpembelelo yobuhle. Iingcingo zesithethi zinokuthi zingabonakali kwaye zinzima ukufihla, ngokukodwa kwiindawo ezincinci okanye ezilungiselelwe kakuhle. Oku kukhokelele ekuphuhliseni ezinye izisombululo, ezifana nezithethi ezingenazingcingo, nangona ezi zisenokungasoloko zihambelana nomgangatho wesandi ophunyezwayo kunye nenkqubo enentambo yokuseta kakuhle.
Indlela yokukhetha ucingo lwesithethi
Ukukhetha ucingo olufanelekileyo lwesithethi kubandakanya ukuqwalasela iinkalo eziliqela, kuquka ubude, igeyiji, izinto eziphathekayo, nokugquma. Ubude bocingo olufunekayo buxhomekeke kumgama phakathi kweamplifier yakho kunye nezithethi. Kuhlala kungcono ukuba nentwana eyongezelelweyo kunokolula ucingo ngokuqinileyo, njengoko oku kunokuchaphazela ukusebenza.
Igeyiji yocingo ibalulekile; okukhona ucingo lubaleka, kokukhona ucingo kufuneka lube ngqindilili ukunqanda ukulahleka komqondiso. Umgaqo omhle wesithupha kukusebenzisa ucingo lwe-16-gauge kumgama ukuya kwi-20 feet, i-14-gauge ukuya kwi-40 yeenyawo, kunye ne-12-gauge ukuya kwi-60 ezinyaweni. Ukuqhuba ixesha elide kakhulu okanye ukusetyenziswa kwamandla aphezulu, ucingo lwe-10-gauge lunokuba yimfuneko.
Umbandela yenye into ebalulekileyo ekufuneka iqwalaselwe. I-Copper iyona nto ixhaphakileyo ye-conductor ngenxa ye-conductivity yayo egqwesileyo kunye nokuqina. Ezinye iingcingo zisilver-plated, ezinokuthi zibonelele ngokuphucuka okuncinci kwi-high-frequency transmission kodwa ngexabiso eliphezulu. I-Insulation nayo ingundoqo, njengoko ikhusela ucingo emonakalweni kwaye inciphisa ukuphazamiseka kwezinye izixhobo zombane.
Indlela yokusebenzisa ucingo lwesithethi
Ukusebenzisa ucingo lwesithethi ngokufanelekileyo kufuna ukucwangciswa ngenyameko nokufakwa. Qala ngokulinganisa umgama phakathi kweamplifier yakho kunye nezithethi ukumisela ubude bocingo olufunekayo. Kuyacetyiswa ukuba wongeze ubude obuncinci ukulungiselela naluphi na utshintsho olungalindelekanga kulungiselelo.
Xa udibanisa ucingo, qinisekisa ukuba i-polarity iyahambelana kuzo zombini iziphelo-ininzi iingcingo zesithethi zineempawu zokwahlula abaqhubi ababini. I-polarity engahambelaniyo inokukhokelela kwimibandela yesigaba, echaphazela kakubi umgangatho wesandi. Ukuqhawula iziphelo zocingo kunye nokwenza uqhagamshelwano olucocekileyo, olukhuselekileyo kwii-terminals lubalulekile ekugqithiseni umqondiso ofanelekileyo.
Ukuhambisa ucingo kunokuchaphazela ukusebenza kunye nobuhle. Kuphephe ukusebenzisa iingcingo zesithethi ezinxuseneyo neentambo zombane ukunciphisa uphazamiseko lombane. Cinga ngokusebenzisa izisombululo zolawulo lwentambo ukugcina iingcingo zicocekile kwaye zingabonakali, ngakumbi kwiindawo zokuhlala.
Isiphelo:
Ucingo lwesipika yinxalenye esisiseko yayo nayiphi na inkqubo yomsindo, echaphazela yonke into ukusuka kumgangatho wesandi ukuya ekubekweni kwesithethi. Ngokuyiqonda indlela esebenza ngayo kunye nezinto ezibandakanyekileyo ekuyikhetheni nasekuyisebenziseni, unokwandisa kakhulu amava akho okuphulaphula. Nokuba ungumntu ozinikeleyo we-audiophile okanye umphulaphuli oqhelekileyo, ukutyala ixesha kunye neenzame ekukhetheni ucingo oluchanekileyo lwesithethi kunokuhlawula imbuyekezo kumgangatho wesandi esiveliswa yinkqubo yakho.
