Ubuchwepheshe sebuhambe ibanga elide kusukela kwafakwa i-tweeter yami yokuqala eminyakeni engu-15 edlule, futhi ama-tweeter amaningi esimanje manje afika ne-crossover eyakhelwe ngaphakathi. Kodwa ungathola ezinye ngaphandle kwe-crossover. Kulezi zimo, uma wazi ukubaluleka kwe-crossover, uyazi ukuthi awusoze wafaka ama-tweeters ngaphandle kwawo. Namuhla ngizogxila endleleni yokuxhuma ama-tweeters e-crossover ku-amplifier.
Ngokuvamile, ukuxhuma i-tweeter nge-crossover eyakhelwe ngaphakathi ku-amplifier, landela lezi zinyathelo.
- Okokuqala, xhuma ucingo oluhle lwe-crossover ku-terminal enhle ye-amplifier.
- Bese uxhuma intambo engalungile ye-crossover kutheminali engalungile ye-amplifier.
- Bese uxhuma ezinye iziphetho ze-crossover ku-tweeter (enhle nebi).
- Ekugcineni, xhuma abanye abashayeli abanjengama-woofers noma ama-subwoofers ku-amplifier.
Yilokho kuphela. Manje isistimu yakho yomsindo wemoto izosebenza kahle.
Ulwazi olubalulekile mayelana nama-tweeter nama-crossovers
Ngaphambi kokuthi siqale inqubo yokuxhuma, kuyadingeka ukuthi sibe nolwazi oluthile mayelana nama-tweeters nama-crossovers.
Yini i-tweeter?
Ukuze ukhiqize kabusha amafrikhwensi aphezulu angu-2000–20000 Hz, uzodinga i-tweeter. Lawa ma-tweeters angaguqula amandla kagesi abe amaza omsindo. Ukuze wenze lokhu, basebenzisa i-electromagnetism. Ngokuvamile ama-tweeter mancane kunama-woofers, ama-subwoofers kanye nama-midrange driver.
ama-woofers: Ama-Woofers ayakwazi ukukhiqiza kabusha amaza kusuka ku-40 Hz kuya ku-3000 Hz.
Ama-Subwoofers: Amathuba okukhiqizwa kabusha kwamafrikhwensi ukusuka ku-20 Hz kuye ku-120 Hz.
Abashayeli beMidrange: Amathuba okukhiqizwa kabusha kwamafrikhwensi ukusuka ku-250 Hz kuye ku-3000 Hz.
Njengoba ungacabanga, isistimu yakho yomsindo wemoto idinga okungenani abashayeli ababili noma ngaphezulu kwabangenhla. Uma kungenjalo, ngeke ikwazi ukubamba amaza athile.
Iyini i-crossover?
Nakuba izishayeli zezipikha zezingxenye zenzelwe ukukhiqiza kabusha ifrikhwensi ethile, lezi zishayeli azikwazi ukuhlunga amafrikhwensi. Ukuze wenze lokhu, udinga i-crossover.
Ngamanye amazwi, i-crossover isiza i-tweeter ukuthatha amaza phakathi kuka-2000-20000 Hz.
Ungawaxhuma kanjani ama-tweeters ku Ama-crossovers akhelwe ngaphakathi ku-amplifier
Kuye ngesimo sakho, kungase kudingeke uthathe izindlela ezahlukene lapho uxhuma i-tweeter yakho. Isibonelo, amanye ama-tweeter anama-crossovers akhelwe ngaphakathi kanti amanye awanawo. Ngakho-ke, endleleni 1, sizoxoxa ngama-crossovers eyakhelwe ngaphakathi. Sizogxila kuma-crossovers azimele ngezindlela 2, 3 no-4.
Indlela 1 - i-tweeter ene-crossover eyakhelwe ngaphakathi
Uma i-tweeter iza ne-crossover eyakhelwe ngaphakathi, ngeke ube nezinkinga zokufaka i-tweeter nokuyixhuma. Xhuma i-tweeter eholayo ekugcineni kwe-amplifier. Bese uxhuma ucingo olunegethivu ekugcineni okunegethivu.
Bese ukhumbula: Ngale ndlela, i-crossover ihlunga kuphela amaza we-tweeter. Ngeke isekele abanye abashayeli abafana nama-woofers noma ama-subwoofers.
Indlela yesi-2 - Ukuxhuma i-Tweeter Ngqo ku-Amplifier nge-Crossover kanye nesipikha se-Full Range
Ngale ndlela, uzodinga ukuxhuma i-crossover ngqo ku-amplifier. Bese uxhuma ezinye iziphetho ze-crossover ku-tweeter. Okulandelayo, sixhuma bonke abanye abashayeli ngokusho komdwebo ongenhla.
Le ndlela ilungele ukuxhuma i-crossover ehlukile ku-tweeter. Kodwa-ke, i-crossover isekela kuphela i-tweeter.
Indlela yesi-3 - Ukuxhuma i-tweeter kanye nesipika sobubanzi obugcwele
Okokuqala, xhuma intambo ephozithivu yesipika sobubanzi obugcwele ku-amplifier.
Bese ulandela inqubo efanayo yocingo olunegethivu.
Bese uxhuma izintambo ezinhle nezimbi ze-crossover emikhawulweni emihle nengalungile yesipika.
Ekugcineni, xhuma i-tweeter ku-crossover. Lena indlela enhle yokulondoloza intambo yesipikha.
Indlela yesi-4 - ukuxhumana okuhlukile kwe-tweeter ne-subwoofer
Uma usebenzisa i-subwoofer ene-tweeter, yixhume ngokuhlukana ne-amplifier. Uma kungenjalo, ukuphuma kwe-bass ephezulu kungalimaza noma kuqhume i-tweeter.
Okokuqala, xhuma ucingo oluhle lwe-crossover ku-terminal enhle ye-amplifier.
Bese uxhuma ucingo olunegethivu ekugcineni okunegethivu. Bese uxhuma i-tweeter ku-crossover. Qinisekisa ukuthi uxhuma izintambo ngokuvumelana ne-polarity.
Manje xhuma izintambo ezinhle nezingezinhle ze-subwoofer kwesinye isiteshi se-amplifier.
Amanye amathiphu angasiza izinqubo ezingenhla
Ama-amplifiers ezimoto zanamuhla aneziteshi ezi-2 kuye kwezi-4. Lawa ma-amplifiers angashayela kanyekanye i-tweeter engu-4 ohm kanye nesipikha sebanga eligcwele elingu-4 ohm (uma sixhunywe ngokuhambisana).
Amanye ama-amplifiers eza nama-crossovers akhelwe ngaphakathi. Ungasebenzisa lawa ma-crossovers akhelwe ngaphakathi ngaphandle kwezinkinga. Njalo sebenzisa i-tweeter crossover. Futhi, ungalokothi uxhume i-tweeter ne-subwoofer.
Kulabo abafuna ukuthuthukiswa, kuhlala kungcono ukushintsha i-crossover yasekuqaleni nge-crossover enezipikha ezinezindlela ezimbili.
Okufanele ukunake ngesikhathi se-wiring
Ngaphandle kwezintambo ezifanele, ngeke ukwazi ukuxhuma ama-tweeter, ama-crossovers, noma ama-subwoofers ngendlela efanele. Ngakho-ke, landela le mihlahlandlela ukuze uthole imiphumela emihle.
- Ungaphambanisi i-polarity yezintambo. Ezibonelweni ezingenhla, kungase kudingeke ubhekane nezintambo ezi-4 noma ezi-6. Ngakho-ke, khomba izintambo ngendlela efanele futhi uxhume izintambo ngokufanele. Imigqa ebomvu imele izintambo eziphozithivu kanti imigqa emnyama imele izintambo ezingezinhle.
- Sebenzisa izixhumi ze-crimp esikhundleni se-tape kagesi. Ziyizinketho ezingcono kakhulu zenqubo ye-wiring enjalo.
- Kukhona osayizi abaningi abahlukene bezixhumi ze-crimp emakethe. Ngakho-ke qiniseka ukuthi uthenga elungele izintambo zakho.
- Sebenzisa i-gauge wire engu-12 kuya ku-18. Kuye ngamandla nebanga, igeji ingahluka.
- Sebenzisa amathuluzi afana nezintambo zokukhumula izintambo namathuluzi okubopha phakathi nenqubo yokuxhuma engenhla. Ukuba namathuluzi anjalo kungenza umehluko omkhulu. Isibonelo, i-wire stripper iyindlela engcono kakhulu kunommese womsebenzi. (1)
Ungawafaka kuphi ama-tweeters
Uma ufuna indawo ongafaka kuyo i-tweeter, zama ukuyibeka phakathi nendawo yezihlalo zabagibeli nezabashayeli.
Futhi, umnyango wemoto noma izinsika eziseceleni eduze kwe-windshield nazo ziyizindawo ezinhle zokubeka i-tweeter. Ama-tweeter amaningi afakwe efekthri afakiwe kulezi zindawo.
Kodwa-ke, lapho ufaka ama-tweeters, qiniseka ukuthi ukhetha indawo efanelekile. Isibonelo, abanye abantu abathandi ukufaka i-tweeter phakathi nendawo kudeshibhodi. Umsindo oqhubekayo eduze nezindlebe ungabacasula. Isicabha semoto siyindawo efanelekile yalesi simo. Futhi, uma ufaka i-tweeter emnyango wemoto; Izinqubo zokumba nokufaka zilula.
Ngingakwazi ukusebenzisa ama-tweeter ku-monoblock subwoofer?
I-monoblock sub amp inesiteshi esisodwa kuphela futhi leso siteshi ngesokukhiqiza kabusha kwe-bass. Ama-amplifiers e-Monoblock awanawo ama-frequency aphezulu. Ngakho-ke, awukwazi ukufaka i-tweeter ku-monoblock amplifier.
Nokho, uma usebenzisa i-amplifier eneziteshi eziningi ene-low pass crossover, landela lezi zinyathelo ezingezansi ukuze usebenze kahle. (2)
- Uma usebenzisa i-amplifier eneziteshi eziningi, xhuma njalo i-tweeter esiteshini esingasetshenzisiwe esigcwele uhla.
- Uma usebenzisa izipikha, xhuma i-tweeter ngokuhambisana nezipikha.
- Kodwa-ke, uma zingekho iziteshi ezingasetshenzisiwe ku-amplifier, ngeke ukwazi ukuxhuma ku-twitter.
Ithiphu: Ama-cross-pass crossovers avimba amaza aphezulu futhi avumela amafrikhwensi ukusuka ku-50 Hz kuye ku-250 Hz ukuthi asetshenziswe.
Ukufingqa
Kungakhathaliseki ukuthi uthenga i-tweeter ene-crossover eyakhelwe ngaphakathi noma i-crossover ehlukile, udinga ukuxhuma i-tweeter ne-crossover ku-amplifier. Indlela engcono kakhulu yokwenza lokhu ukuxhuma i-tweeter esiteshini esingasetshenzisiwe.
Ngakolunye uhlangothi, uma usebenzisa i-subwoofer ene-tweeter, landela iziqondiso ezingenhla ngendlela efanele.
