Yintoni i-subwoofer yemoto
I-subwoofer yemoto yinxalenye ebalulekileyo kwinkqubo yesandi semoto enoxanduva ngokukodwa lokuphinda izandi eziphantsi kwesandi (ngesiqhelo ukusuka kwi-20Hz ukuya kwi-250Hz). Umsebenzi wayo ophambili kukuguqula imiqondiso ye-elektroniki ibe ngamaza esandi aphantsi ukuze iveze iziphumo zebhesi ezifana needrama, iibhesi, kunye nokugquma kweenjini, ukuphucula ukubekwa kunye nokuntywiliselwa kweziphumo zesandi zomculo okanye zeemuvi.I-Youdaoplaceholder0 Ngokwesakhiwo kunye nomgaqo wokusebenza, isithethi se-bass yemoto sidla ngokwakhiwa yinkqubo yamandla kagesi (njengeemagnethi, iikhoyili zelizwi), inkqubo yokungcangcazela koomatshini (njengee-diaphragms, amaza entwasahlobo), kunye nenkqubo yokuxhasa isakhelo. Ivelisa intsimi yemagnethi ngokuqhuba ikhoyili yelizwi ngotshintsho kumbane, nto leyo eqhuba ikhoyili ukuba ingcangcazele kwaye ityhale umoya ukuba uvelise isandi. Idla ngokusebenzisa iikhoyini zephepha ezixineneyo kunye neekhoyili zelizwi eziqinisiweyo ukuhlangabezana neemfuno ze-amplitudes ezinkulu ze-low-frequency, ezihambelana ne-tweeter (enoxanduva lwenxalenye ye-high-frequency).
Kwinkqubo yesandi semoto, indawo yokufakela i-subwoofer (njengasecangweni lemoto, ezantsi okanye kwikhabhinethi enikezelweyo) iya kuchaphazela amandla kunye nemvakalelo yendawo ye-bass. Ngenxa yemida yeendleko, inkqubo yesandi semoto yokuqala idla ngokuxhotyiswa kuphela ngezithethi ezipheleleyo, nto leyo ebangela i-bass encinci. Ukufaka i-subwoofer enikezelweyo kunokuphucula kakhulu amava okumamela. Ihlala isebenza kunye ne-crossover okanye idityaniswe kwi-subwoofer ukuphucula isiphumo se-frequency esiphantsi kakhulu.
I-subwoofer emotweni yinxalenye yenkqubo yesandi enoxanduva ngokukodwa lokuphinda izandi eziphantsi kwesandi (ngesiqhelo ukusuka kwi-20Hz ukuya kwi-200Hz). Umsebenzi wayo ophambili kukuphucula impendulo esezantsi kwesandi, okwenza isandi somculo nesemuvi sibe ngqindilili kwaye sigxile ngakumbi.
I-subwoofer inokuphucula kakhulu amava okuva . Ngokuphinda ivelise izinto eziphantsi kwesandi ezifana needrama kunye ne-bass, yenza isingqisho sibe namandla ngakumbi kwaye umoya ube mhle ngakumbi. Ingakumbi xa udlala umculo we-elektroniki okanye iimuvi zentshukumo, inokudala uvakalelo lokuntywiliselwa kunye nefuthe.
Kwimeko enengxolo, isithethi se-bass sinoku "fihla" ukuphazamiseka kwesandi esiphantsi. Ingxolo yenjini kunye nesandi somoya esiveliswa yimoto ngexesha lokusebenza zingaphantsi kwe-200Hz, nto leyo enokuyifihla ngokulula inxalenye yomculo enesandi esiphantsi. I-subwoofer igubungela ezi ngxolo ngokunyusa uxinzelelo lwesandi esiphantsi kwaye ibuyisele ibhalansi yomculo.
Ngokwembono yobuchwephesha, i-subwoofer isebenzisa i-diaphragm enobubanzi obukhulu kunye nenkqubo yesekethe enamandla yemagnethi ukuqhuba umoya omninzi, nto leyo ephucula inqanaba loxinzelelo lwesandi kunye neempawu zexesha elifutshane. Ukulungisa uyilo lwekhabhinethi kunokwandisa ulwandiso oluphantsi, okwenza i-bass igcwale ngakumbi.
Ukungasebenzi kakuhle kwe-subwoofer yemoto kunokubangelwa zizinto ezahlukeneyo. Oku kulandelayo kubonelela ngeengcinga zokusombulula iingxaki kunye nezisombululo ngokusekelwe kwiimeko eziqhelekileyo. Kucetyiswa ukuba uqale ngezinto ezilula uze uhlolisise nzulu kancinci kancinci.
Amanyathelo okusombulula iingxaki ze-Youdaoplaceholder0: Okokuqala, qinisekisa ububanzi bempazamo kwaye ujonge ukuba yonke inkqubo ye-horn yesithuthi ayisebenzi kakuhle okanye inxalenye ye-bass kuphela ayiqhelekanga. Ukuhlolwa koqhagamshelo lwesekethe ye-Youdaoplaceholder0 kuquka:
Jonga ukuba ifusi ivuthile na (umzekelo, ifusi yeHORN yeBYD F3 ikwibhokisi yefusi yasekhohlo yekhabini yomqhubi, ebhalwe "Horn", enomlinganiselo wamandla we-15A). Ukuba ivuthile, kufuneka itshintshwe kwaye unobangela we-short circuit kufuneka uphandwe.
Jonga ukuba iibhloko zesiphelo sesithethi zikhululekile okanye zi-oxidized na kwaye uqinisekise ukuba iplagi iqinile.
Ukuhlolwa komzimba wesithethi se-Youdaoplaceholder0 kungenziwa ngeendlela ezilandelayo:
Linganisa ukumelana kwee-terminals zesithethi nge-multimeter. Ixabiso eliqhelekileyo limalunga ne-3 ukuya kwi-5 ohms. Ukuba ibonisa ukungapheli (OL), ikhoyili yangaphakathi inokutsha.
Cinezela uze ubambe iqhosha lexilongo ixesha elide, uze umamele kufutshane nexilongo ukuze ubone ukuba kukho isandi sexilongo esithi "tap-tap". Ukuba akukho sandi kodwa akukho sandi, oko kubonisa ukuba ixilongo lonakele kwaye kufuneka litshintshwe. Ukuba akukho sandi, gxila ekujongeni isekethe.
Xa ujonga umgca kunye nezinto zangaphandle, nceda uqaphele:
Jonga ukuba iingcingo zindala, zonakele okanye azinazo na iingcingo ezidityanisiweyo kakuhle, ingakumbi i-clock spring (hairspring) engaphantsi kwevili lokuqhuba, enokuqhekeka ngenxa yokujikeleza rhoqo.
Kuphephe ukusebenzisa umpu wamanzi ngqo kwi-horn xa uhlamba imoto ukuthintela amanzi ukuba angangeni aze abangele umhlwa.
Useto lwenkqubo yesandi ye-Youdaoplaceholder0 kunye nemiba yolondolozo lobungcali:
Lungisa isilinganisi sesandi ukuqinisekisa ukuba ivolumu yebhesi ayicinywanga okanye ayibekwanga phantsi kakhulu.
Ukuba kukho isikrokro sokuba kukho ingxaki kwi-power amplifier okanye kwi-subwoofer, kufuneka izixhobo zobungcali ukuze kuvavanywe amandla aphumayo.
Ukuba ingxaki iyaqhubeka emva kokuzihlola, kuyacetyiswa ukuba uqhagamshelane nabasebenzi bokulungisa abangochwephesha ukuze uphephe umonakalo ongakumbi obangelwa kukusebenza ngokungaboni.
