Ama-crossovers e-car audio cishe amanye amakhemikhali alalelwayo angaqondakali kakhulu lapho. Njengoba kungadingekile kakhulu, kulula kakhulu ukuvele ucabange ngale ndaba lapho usakha noma uthuthukisa uhlelo lokulalelwayo lwemoto. Ama-head units, amplifiers, nezikhulumi zithola yonke imithombo emihle, kepha lokho akusho ukuthi ama-crossovers awabalulekile.
Ukuze uqonde ukuthi i-crossover iyini, nokuthi ngabe imishini yomsindo wezimoto idinga ngempela yini noma ngaphezulu, kubalulekile ukuthi uqale uqonde izimiso ezithile eziyisisekelo ezisekela ukusetshenziswa kwe-audio crossover ukusetshenziswa.
Umqondo oyisisekelo wukuthi umculo uqukethe ama-frequencies e-audio asebenzisa wonke ama-gamut wokuzwa kwabantu, kodwa ezinye izikhulumi zingcono ekukhiqizeni ama-frequencies aqondile kunabanye. Abathengisi baklanyelwe ukuzala ama-high frequencies, ama-woofers aklanyelwe ukuzala ama-frequencies aphansi, njalonjalo.
Ngalokho engqondweni, ama-newbies omculo wemoto avame ukumangala uma ezwa ukuthi yonke imishini yomsindo wemoto ikhona ngempela idinga ama-crossovers kwelinye elilodwa noma elinye. Isibonelo, izinhlelo eziyisisekelo ezisebenzisa izikhulumi ze-coaxial empeleni zinama-crossovers amancane akhiwe ngqo kuzikhulumi. Ezinye izinhlelo, ikakhulukazi ezisebenzisa izikhulumi zezingxenye, ngokuvamile zisebenzisa ama-crossovers angaphandle adlulisa ama-frequencies afanele ezikhulwini ezifanele.
Inhloso eyinhloko yokwephula umculo zibe ngamafomu, futhi ukuthumela kuphela ama-frequencies athile kuzikhulumi ezithile, ukufeza ukuthembeka okuphezulu kwe-audio. Ngokuqinisekisa ukuthi ama-frequencies amahle kuphela afinyelela ezikhulumeni ezifanele, ungakwazi ukunciphisa ngokuphambene ukuphazamiseka nokusiza ukuthuthukisa izinga elizwakalayo lomsindo womsindo wemoto.
Izinhlobo ze-Car Audio Crossovers
Kunezinhlobo ezimbili eziyinhloko zama-crossovers, okuyizona ezifaneleke kakhulu ezimweni ezithile:
- I-Passive Crossovers
- Lawa ma-crossovers ahlala phakathi kwe-amp kanye nezikhulumi, futhi ahlunga ama-frequencies angafuneki. Ezinye izikhulumi ziye zakha izikhonkwane ezingezansi. Njengoba la ma-crossovers ephihliwe phakathi kwe-amp kanye nezikhulumi, kulula ukufaka. Kodwa-ke, kunesilinganiso esithile sokungasebenzi kahle okuhambisana nezikhonkwane ezihamba phambili.
- I-Crossovers esebenzayo
- Lezi ziyaziwa nangokuthi ama-crossovers e-elektronike, futhi zombili ziyinkimbinkimbi futhi ziyabiza ngaphezu kwama-unit units. Ama-crossovers asebenzayo adinga imithombo yamandla, kodwa awachithi amandla ngokuhlunga izimpawu eziphakanyisiwe ngendlela okwenza ngayo ama-crossovers angenayo.
Ubani Ngempela Odingayo I-Crossover Audio Audio?
Iqiniso liwukuthi yonke imishini yomsindo wemoto idinga uhlobo oluthile lwe-crossover ngendlela efanayo ukuthi yonke uhlelo lwe-audio yemoto idinga uhlobo oluthile lwe-amplifier . Kodwa ngendlela efanayo ngqo ukuthi izinyunithi eziningi zekhanda zihlanganisa i-amplifier eyakhelwe ngaphakathi, izikhulumi zingabuye zihlanganise nezikhonkwane ezakhelwe ngaphakathi. Ezisekelweni eziyisisekelo zokulalelwayo kwemoto , kungenzeka ngokuphelele ukuthola ngokuhle ngaphandle kwama-crossovers engeziwe. Noma kunjalo, kunezimo eziningana lapho i-unit engekho noma esebenzayo iyothuthukisa ikhwalithi yomsindo, ukusebenza kahle kohlelo, noma kokubili.
Uma uhlelo lwakho lwomsindo wezimoto lisebenzisa izikhulumi ze-coaxial , cishe awudingi i-crossover eyengeziwe. Izipikha zezinhlavu ezigcwele zivele zakhiwe izikhonkwane ezihamba phambili ezihlunga amafreedom afinyelela umshayeli ngamunye. Ngisho noma ufaka i-amplifier ku-mix, izakhi ezikhulisiwe ezikhulwini kumele zibe ngaphezu kokwanele. Kodwa-ke, ungase udinga i-crossover uma ufaka i-amplifier ne- subwoofer kulolo hlobo lwesistimu.
Ngakolunye uhlangothi, ngokuvamile uzodinga i-crossovers eyodwa noma ngaphezulu uma uhlela ekwakheni uhlelo oluqukethe izikhulumi, izingxubevange eziningi, nama-subwoofers. Lokhu kuyiqiniso ikakhulukazi uma uhlela ukusebenzisa abathuthukisi abathile ukushayela izipikha ezithile, njengama-woofers akho noma ama-tweeters. Kungakhathaliseki ukuthi ukhetha ama-crossovers asebenzayo noma asebenzayo, uzodinga okuthile ukugcina ama-frequencies angathandeki ekufinyeleleni izikhulumi.
Kubalulekile ukuthi uqaphele ukuthi ama-amplifiers emva kwe-backmarket afaka phakathi izihlungi ezakhelwe ngaphakathi ezenza ngokuphumelelayo njengama-crossovers uma wakhe isistimu yomsindo wezimoto eziyisisekelo ngezikhulumi zenkampani. Isihlungi sokupasa esiphezulu kule hlobo lokukhulisa ikuvumela ukushayela ama-tweeters, futhi isihlungi esedlule esiphambanweni sikuvumela ukushayela ama-woofers, ngaphandle kokudinga ama-crossovers engeziwe.
Uma i-Crossover esebenzayo ingasiza ngempela
Ngenkathi ungathola ngokuhamba kahle ngaphandle kwe-crossover esimweni lapho usanda kusebenzisa i-amplifier eyodwa, ukwakheka okunzima kakhulu kunokwengeziwe kuzuza ku-crossover esebenzayo. Isibonelo, i-crossover ye-3 yindlela oyithinta ngayo phakathi kweyunithi yakho yekhanda nama-amplifiers amaningi.
Kulesi simo, i-amplifier ngayinye ithola uhla oluthile lwamagagasi avela ku-crossover, futhi isikhulumi ngasinye sisetshenziselwa ukushayela uhlobo oluthile lwesipikha. Isibonelo, omunye angashayela izikhulumi zangaphambi kokudlula okuphezulu, omunye angase aqhube izikhulumi eziphelele zezinhlavu ezigcwele, futhi i- subwoofer amp yesithathu ingadlulisa i-sub.
Ingabe i-Crossovers idinga ukufakwa kobuchwepheshe?
Ukufaka ama-crossovers akuyona i-rocket isayensi, kodwa uzodinga ukuqonda okuyisisekelo kwalokho okwenzayo ngaphambi kokwenza lolu hlobo lwephrojekthi ye-DIY. Ukufaka i-crossover engenamaphutha kulula ngoba kuhlanganisa ukuhlanganisa i-wiring ne-crossover phakathi kwe-amp yakho nezikhulumi zakho. Isibonelo, ungase uhambise i-crossover engenayo kumkhiqizo wakho we-amplifier, bese ufaka umkhiqizo we-crossover's tweeter ku-tweeter yakho kanye nomkhiqizo we-woofer ku-woofer yakho.
Ukufaka i-crossover yemoto esebenzayo ngokuvamile kuyoba yinkambinkimbi eyinkimbinkimbi. Inkinga enkulu ukuthi ama-crossovers asebenzayo adinga amandla, ngakho-ke uzodingeka ugijime amandla kanye nezintambo zomhlabathi ekamelweni ngalinye. Izindaba ezinhle ukuthi uma usuvele ufaka i-amplifier, kufanele ube ngaphezu kokukwazi ukufaka i-crossover esebenzayo kusukela i-wiring ayiyona eyinkimbinkimbi nakakhulu. Eqinisweni, ukusekela i-crossover yakho esebenzayo endaweni efanayo ubeke umakaki wakho kuzosiza ukuvimbela ukuphazamiseka komhlabathi okucasulayo .
