Izixhobo zokuphulaphula imoto mhlawumbi ezinye zezinto ezivakalayo ezingenakuqondwa zilapho. Ekubeni kungabalulekanga nakakhulu, kulula kakhulu ukugubungela yonke into xa usakha okanye uhlaziya inkqubo yomsindo wemoto. Iiyunithi zeentloko, izikhulisi kunye neentetho zifumana yonke into efanelekileyo yokushicilela, kodwa oko akuthethi ukuba ama-crossover ayabalulekanga ngokunjalo.
Ukuze uqonde ukuba yiyiphi i-crossover, kwaye nokuba ingekho imvalo yemoto eyakhayo ngokwenene idinga enye okanye ngaphezulu, kubalulekile ukuba uqale uqonde imigaqo ethile ebalulekileyo exhasa ukusetyenziswa kwee-carssover usetyenziso.
Ingcamango engundoqo kukuba umculo uqulethwe ngamazwi ovakalayo aqhuba lonke i-gamut yeentetho zabantu, kodwa ezinye iithethi zilungele ukuvelisa ii-frequencies ezithile. Abathengisi benzelwe ukuvelisa iifrikanti eziphezulu, i-woofers zenzelwe ukuvelisa ama-frequencies aphantsi, njalo njalo.
Ngaloo nto, iingcamango zomsindo weemoto zivame ukutshatyalaliswa xa zifumanisa ukuba yonke inkqubo yemisindo yemoto ikhona ngokwenene idinga i-crossovers kwinqanaba elinye okanye elinye. Ngokomzekelo, iisiseko ezisisiseko ezisetyenziselwa izivakalisi ezinxibelelwano zinezona zincinci ezincinci ezakhiwe ngqo kwizithethi. Ezinye iinkqubo, ngokukodwa ezisebenzisa izithethi zecandelo, ngokuqhelekileyo zisebenzisa i-crossovers zangaphandle ezigqithiseleyo iifom ezifanelekileyo kwiithethi ezichanekileyo.
Injongo ephambili yokuphula umculo kumabonakude ombane, kwaye ukuthumela kuphela ii-frequencies ezithile kwiithethi ezithile, kukufumana ukuthembeka okuphezulu kwomsindo. Ngokuqinisekisa ukuba iifayile ezifanelekileyo kuphela zifikelela kwizivakalisi ezifanelekileyo, unokunciphisa ngempumelelo ukuphazamiseka kwaye uncede ukuphucula umgangatho osemgangathweni womsindo womsindo wemoto.
Iintlobo ze-Car Audio Crossovers
Kukho iintlobo ezimbini eziphambili zeengqungquthela, ngasinye ngasinye esifanelekileyo kwiimeko ezithile:
- Passive Crossovers
- Ezi zikhonkwane zihlala phakathi kwe amp amp and speakers, kwaye zihluza ngaphandle ii-frequencies ezingafunekiyo. Ezinye izithethi ziye zakha izikhonkwane ezingabonakaliyo. Ekubeni la ma-crossovers afakwe kwi-amp amp and speakers, kulula ukuba bafake. Nangona kunjalo, kukho inani elithile lokungafezekisi olulinganiselwe kwii-crossovers ezingenanto.
- Crossovers esebenzayo
- Ezi ziyaziwa ngokuba yizixhobo zokusebenzisa i-electronics, kwaye zibini ziyinkimbinkimbi kwaye zibiza ngaphezu kweeyunithi ezingekho. Izikhukhula ezisebenzayo zidinga imithombo yamandla, kodwa ayichitha amandla ngokucoca izibonakaliso eziphakanyisiweyo ngendlela eyenziwa ngayo.
Ngubani Ubani Unayo Imfuno Yomsindo weCarvey Crossover?
Inyaniso kukuba yonke inkqubo yomsindo wemoto idinga uhlobo oluthile lwe-crossover ngendlela efanayo ukuba yonke inkqubo yesandi yemoto idinga uhlobo oluthile lwe-amplifier . Kodwa ngendlela echanekileyo leyo ininzi yeeyunithi zeentloko ziquka i-amplifier eyakhelwe ngaphakathi, izithethi zingabandakanya kwakhona izakhiwo ezikwakhelwe ngaphakathi. Kwiinkqubo ezisemgangathweni zomsindo weemoto , kunokwenzeka ukuba kufikeleleke ngokugqibeleleyo ngaphandle kwee-crossovers ezongeziweyo. Nangona kunjalo, kukho iimeko ezininzi apho iinqununu ezingasebenzi okanye ezisebenzayo ziya kuphucula umgangatho wezandi, ukusebenza kweenkqubo, okanye zombini.
Ukuba inkqubo yakho yokulalelwayo yemoto isebenzisa izithethi ze-coaxial , mhlawumbi awudingi i-crossover eyongezelelweyo. Iintetho ezipheleleyo ezikhoyo sele zizakhele izikhonkwane ezingenanto ezicoca iziganeko ezifikelela kumqhubi ngamnye. Nokuba udibanisa i-amplifier kumxube, izakhelo ezithengiweyo kwisigidi-sithethi kufuneka zibe ngaphezu kokwaneleyo. Nangona kunjalo, ungadinga i-crossover xa ukongeza i-amplifier kunye ne- subwoofer kulolo hlobo lwenkqubo.
Ngakolunye uhlangothi, kuya kufuneka ukuba ufune enye okanye ngaphezulu kwi-crossovers ukuba ucwangcise ekwakheni inkqubo equlethe izithethi zecandelo, izikhulu ezininzi, kunye ne-subwoofers. Oku kuyinyani ngokukhethekileyo xa uceba ukusebenzisa abathuthukisi bomntu ngamnye ukuqhuba izithethi ezithile, ezifana ne-woofers yakho okanye i-tweeters. Enoba ukhetha i-crossovers esebenzayo okanye engabonakaliyo, uya kufuna into yokugcina iifom ezingabonakaliyo ukufikelela kwiintetho.
Kubalulekile ukuba uqaphele ukuba emva kwee-markmarket amplifiers zibandakanya izihlungi ezakhelwe ngaphakathi ezisebenza ngokufanelekileyo njengezitshixo xa ukwakha inkqubo yomsindo wezithuthi kunye nezithethi zecandelo. Ifayile yokupasa ephezulu kule ndlela ye-amplifier ikuvumela ukuba uqhube i-tweeters, kwaye isiqulatho esisezantsi sichaza ukuba uqhube i-woofers, ngaphandle kokufunwa nayiphi na i-crossovers eyongeziweyo.
Xa i-Crossover esebenzayo inokukunceda ngokwenene
Nangona uhlala ufumana kakuhle ngaphandle kwe-crossover kwimeko apho usebenzisa nje i-amplifier enye, ukwakha okunzima kunokuba luncedo kakhulu kwi-crossover esebenzayo. Ngokomzekelo, i-crossover ye-3 yinkalo oyenayo ukucoca phakathi kweyunithi yakho yentloko kunye nama-amplifiers amaningi.
Kulo hlobo lwesimo, i-amplifier nganye ifumana uluhlu oluthile lwee-frequencies ukusuka kwi-crossover, kwaye nganye i-amplifier isetyenziselwa ukuqhuba uhlobo oluthile lwesithethi. Ngokomzekelo, enye inokuqhubela phambili izithethi zangaphambili ezinepasiti ephezulu, enye inokuqhuba izikhulumi ezipheleleyo ezipheleleyo, kunye ne-third subwoofer amp ingaqhuba i-sub.
Ngaba iiCrossovers zidinga ukufakwa koBugcisa?
Ukufaka ii-crossovers akuyiyo i-rocket yesayensi, kodwa uya kufuna ukuqonda okuyisiseko kwento oyenzayo ngaphambi kokuba wenze lolu hlobo lweprojekthi ye-DIY. Ukufaka i-crossover engenakucacile kubonakala kulula kuba kubandakanyeka i-wiring i-crossover phakathi kwe-amp yakho kunye neentetho zakho. Ngokomzekelo, unokwenza ucingo lwe-crossover yakho kwi-amplifier output, uze ufake umkhiqizo we-tweeter kwi-tweeter yakho kunye ne-woofer ephuma kwi-woofer yakho.
Ukufakela i-crossover ye-car esebenzayo iyimfuneko kakhulu. Umba oyintloko kukuba i-crossovers esebenzayo idinga amandla, ngoko kuya kufuneka usebenze amandla kunye neencingo zomhlaba kwiyunithi nganye. Iindaba ezilungileyo kukuba ukuba sele usufake i-amplifier, ngoko kufuneka ube ngaphezu kokukwazi ukufaka i-crossover esebenzayo kuba i-wiring ayikho into enzima kakhulu. Enyanisweni, ukusekela i-crossover yakho esebenzayo kwindawo efanayo ubeka umbane wakho kukunceda ukukhusela ukuphazamiseka komngcipheko womhlaba .
