Ungawaxhuma kanjani ama-tweeters ku-amplifier (izindlela ezi-3)
Okuqukethwe
Ekupheleni kwalesi sihloko, uzokwazi ukuxhuma ama-tweeters akho ku-amplifier.
Ama-tweeter ezimoto, ngisho nalawo ashibhile, angathuthukisa kakhulu isistimu yakho yomsindo ngokudala umsindo wemvamisa ephezulu. Nokho, ungase ungazi ukuthi ungaxhuma kanjani futhi ufake ama-tweeter emotweni. Nokho, kunezindlela eziningana zokuxhuma ama-tweeter emoto, enye yazo ukuxhuma ku-amplifier.
Qhubeka ufunda njengoba sidingida imininingwane ngokuqhubekayo.
Izindlela ezi-3 zokuxhuma ama-Tweeter ku-Aplifier
Ama-tweeter ezimoto anama-crossovers akhelwe ngaphakathi.
Ezimweni eziningi, yakhelwe ngemuva kwe-tweeter noma ibekwe ngqo eduze kwezintambo zesipika. Lawa ma-crossover abaluleke kakhulu uma ufaka ama-tweeters. Bahlukanisa amafrikhwensi futhi baqinisekise ukuthi ngayinye ihanjiswa kudrayivu efanele. Izinga eliphezulu liya kuma-tweeter, ama-mids aya phakathi, futhi ama-lows aya kuma-bass.
Ngaphandle kwama-crossovers, amafrikhwensi azohamba ngendlela engafanele ngokuphelele.
Nazi ezinye izikimu zokuxhuma ama-tweeter ane-crossovers kuma-amplifiers:
Ixhuma ku-amplifier enezipikha ezixhunyiwe noma i-amplifier yesiteshi engasetshenzisiwe enokukhipha okugcwele kwebanga
Ama-Tweeter angaxhunywa ku-amplifier kanye nezikhulumi zamanje zengxenye.
Lokhu kusebenza kuzo zombili izipikha zobubanzi obugcwele nezipikha ezixhunywe kuma-crossovers. Ama-amplifiers amaningi ngokuvamile angaphatha umthwalo ofanayo kuzipikha ezidalwe ngokungeza ama-tweeter. Futhi, namathela ekuxhumekeni kwezintambo ezinhle nezingezinhle ku-amplifier.
Bese uqinisekisa ukuthi i-polarity yesipikha ye-tweeter iyafana (kungaba ku-tweeter noma imakwe ku-crossover eyakhelwe ngaphakathi ye-tweeter).
Inqamula izipikha zobubanzi obugcwele esezixhunyiwe kakade
Unganqamula amatheminali esipikha noma izintambo zesipika zezipikha zezingxenye zobubanzi obugcwele ukuze wenze izinto zibe lula futhi wonge izintambo zesipika.
Ungaphambanisi i-polarity. Ngomsindo wemoto ongcono kakhulu, xhuma intambo yesipika ephozithivu nenegethivu ye-tweeter ngendlela efanayo nezipikha esezixhumeke ku-amplifier. Ungazixhuma ngokuhambisana nezipikha zakho ukuze wonge isikhathi, umzamo, nekhebuli yesipika. Uma nje kuyizipikha ezigcwele uhla, uzothola isignali yomsindo efanayo njengoba uthola ku-amplifier.
Kodwa-ke, angikuncomi lokhu kuzikhulumi ezisebenzisa i-cross pass crossover, kokubili ku-amplifier naphambi kwezikhulumi.
Ixhuma ku-amplifier yesiteshi engasetshenzisiwe ehlukene nama-subwoofers
Kule ndlela, i-amplifier kufanele ibe namashaneli enzuzo ahlukene atholakalayo kanye nokokufaka komsindo kobubanzi obugcwele ukuze kusetshenziswe ne-subwoofer noma i-subwoofers.
Lokhu kungenxa yokuthi iziteshi ze-subwoofer kuma-amplifiers zisetshenziswa kuphela kwimodi yefrikhwensi ephansi, engavumeli ama-tweeters ukuthi akhiqize amaza aphezulu. Futhi, ama-bass aphezulu angagcwala ama-tweeter futhi abangele ukuhlanekezela.
Kungenjalo, sebenzisa ipheya ye-RCA Y-splitters ku-amplifier noma ipheya ye-RCA yobubanzi obugcwele obuphuma kuyunithi yekhanda ukuze uxhume ipheya yesibili yokokufaka kwesignali eziteshini zamahhala zebanga eligcwele le-amplifier.
Xhuma i-RCA yesiteshi se-tweeter kububanzi obugcwele obuphuma phambili noma obungemuva, bese uxhuma okokufaka kwesikhulisi se-subwoofer kumajekhi e-RCA angemuva noma e-subwoofer.
Bese, ukuze ufanise izikhulumi zakho ezikhona, uzodinga ukusetha inzuzo ehloniphekile ye-amp.
Futhi, ama-tweeter awavunyelwe kuma-amplifiers e-monobloc (bass kuphela) noma amashaneli okukhiphayo e-subwoofer ane-pass crossover ephansi.
Okukhishwayo kwe-tweeter ye-high-frequency akutholakali kunoma yisiphi salezi zimo. I-Monoblock (isiteshi esisodwa) ama-amplifiers ama-subwoofers cishe enziwe emhlabeni wonke ngokukhethekile ukukhiqizwa kabusha kwe-bass. Zenzelwe ukukhiqiza amandla engeziwe futhi zishayele ama-subwoofers ngamavolumu aphezulu.
Ngakho-ke akukho treble yokushayela ama-tweeters.
Ukusebenzisa ama-crossovers akhelwe ngaphakathi e-tweeter amplifier
Kulezi zinsuku, ama-cross-pass high and low-pass avame ukufakwa kuma-amplifiers emoto njengesici ozikhethela sona.
Ikhasi lokucaciswa komkhiqizi noma ibhokisi ngokuvamile liqukethe ulwazi mayelana nezici zemvamisa ye-crossover ye-tweeter.
Futhi, ukuze uthole imiphumela engcono kakhulu, sebenzisa i-high-pass amplifier crossover ene-crossover frequency efanayo noma ephansi. Ungasebenzisa lawa ma-crossover amplifier lapho ufaka ama-tweeter anama-crossovers akhelwe ngaphakathi kanje:
Ukusebenzisa i-Amp ne-Tweeter Crossovers
Ukuze uthuthukise ukusebenza kabi kwama-tweeter crossovers akhelwe ngaphakathi angu-6 dB ashibhile, ungasebenzisa ama-tweeter emoto ane-12 dB amplifier high-pass crossover.
Isebenza futhi kuma-tweeter crossovers eyakhelwe ngaphakathi. Setha imvamisa ye-amplifier ukuze ihambisane nemvamisa ye-tweeter. Isibonelo, uma i-tweeter yakho ine-crossover eyakhelwe ngaphakathi engu-3.5 kHz, engu-6 dB/octave, setha i-crossover ye-amplifier ephezulu ibe ngu-12 dB/octave kokuthi 3.5 kHz.
Ngenxa yalokho, ama-bass amaningi angavinjwa, okuvumela ama-tweeter ukuthi asebenze ngamandla futhi akhulume kakhulu ngenkathi ehlangabezana nokuhlanekezela okuncane.
Ukushintsha i-tweeter crossover nge-amplifier crossover
Ungakwazi ukuziba ngokuphelele i-tweeter crossover engabizi ngokusebenzisa i-crossover eyakhelwe ngaphakathi ye-amplifier eyakhelwe ngaphakathi.
Sika noma unqamule izintambo ezinqamulayo zama-crossovers akhelwe ngaphakathi e-tweeter, bese uxhuma izintambo ndawonye. Bese, kuma-tweeters ane-crossover eyakhelwe ngaphakathi ngemuva, solder i-jumper wire ezungeze i-tweeter capacitor ukuze uyidlule.
Ngemuva kwalokho, setha imvamisa ye-high-pass crossover crossover ye-amplifier enani elifanayo nama-crossovers asekuqaleni.
Izintambo zesipikha ezichwepheshile ze-tweeter
Ngeluleka ukuthi kusetshenziswe izixhumi zekhwalithi ephezulu noma nini lapho kunokwenzeka ukuze uthole ikhwalithi ephezulu yokufaka.
Kuthatha izinyathelo ezimbalwa kuphela:
Isinyathelo se-1: Hlubula intambo yesipika bese uyilungiselela isixhumi.
Isinyathelo se-2: Faka ngokuqinile intambo kusixhumi se-crimp (usayizi ofanele).
Isinyathelo se-3: Sebenzisa ithuluzi le-crimping ukuze unqande intambo ngokuphephile nangokufanelekile ukuze udale uxhumano oluhlala njalo.
Ukukhumula izintambo zesipika
Kunamathuluzi amaningi ongawasebenzisa ukuze ukhumule intambo yesipika sakho. Ngiyeluleka ukusebenzisa ithuluzi le-crimping, okuyithuluzi elibiza kakhulu. (1)
Ngokuyisisekelo, bangakwazi ukuhlubula futhi banqume izintambo ngaphezu kokuxhuma izixhumi. Inqubo iwukuncinza i-insulation yocingo, hhayi imicu ngayinye yocingo. Uma ucindezela kakhulu i-stripper bese ugoqa ucingo ngaphakathi, cishe uzonqamula ucingo futhi kufanele uqale phansi. Kungase kube nzima ekuqaleni futhi kudinga ulwazi oluthile.
Ngemva kwemizamo embalwa, ungakwazi kalula ukuhlubula intambo yesipika.
Ukusika intambo yesipika ye-tweeter, landela lezi zinyathelo:
Isinyathelo se-1: Faka ucingo ku-stripper bese uhlwitha ngokucophelela okokufaka endaweni. Faka amandla anele ukuze ubambe ucingo endaweni futhi ucindezele kancane okokufaka, kodwa gwema ukufaka ingcindezi ngaphakathi kwentambo.
Isinyathelo se-2: Bamba ithuluzi ngokuqinile futhi usebenzise ingcindezi ukuze uvimbele ukunyakaza.
Isinyathelo se-3: Donsa ucingo. Intambo engenalutho kufanele ishiywe endaweni uma i-insulation iphuma.
Ezinye izinhlobo zezintambo zinzima kakhulu ukuzihlubula ngaphandle kokuphuka, ikakhulukazi izintambo ezincane ezifana no-20AWG, 24AWG, njll.
Zijwayeze ocingweni olwengeziwe ukuze ungachithi okudingayo ukuze ufake i-tweeter kuma-try ambalwa okuqala. Ngiphakamisa ukususa intambo ngokwanele ukuze kuvezwe u-3/8″ kuya ku-1/2″ yocingo olungenalutho. Izixhumi ze-crimp kufanele zihambisane ne-3/8" noma ngaphezulu. Ungashiyi ubude obuningi, njengoba ngemva kokufakwa kungase kuphumele ngaphandle kwesixhumi.
Ukusebenzisa izixhumi ze-crimp ukuxhuma izintambo unomphela
Ukuze unqamule kahle intambo yesipika, landela lezi zinyathelo:
Isinyathelo se-1: Susa intambo eshiya u-3/8″ ukuya ku-1/2″ yocingo olungenalutho obala.
Isinyathelo se-2: Sonta intambo ngokuqinile ukuze ucingo lukwazi ukufakwa kahle kusixhumi.
Isinyathelo se-3: Iphushe ucingo luqine lungene ekugcineni ukuze uxhume iphini lensimbi ngaphakathi. Qiniseka ukuthi uyifaka ngokuphelele.
Isinyathelo se-4: Eduze kwasekupheleni kwesixhumi, faka isixhumi ethuluzini lokukhiya endaweni efanele.
Isinyathelo se-5: Ukuze ushiye i-imprint ngaphandle kwesixhumi, sisonge ngokuqinile ngethuluzi. Isixhumi sensimbi sangaphakathi kufanele sijikele ngaphakathi futhi sibambe intambo ngokuvikelekile.
Isinyathelo se-6: Kumelwe wenze okufanayo ngocingo lwesipika nolunye uhlangothi.
Amathiphu Abalulekile Wokuxhumanisa ama-Tweeter ku-Amplifier
Uma uxhuma ama-tweeter ku-amplifier, kungcono ukukhumbula lokhu okulandelayo:
- Ngaphambi kokuxhuma, vala ukunikezwa kwamandla okuyinhloko futhi uqiniseke ukuthi azikho izintambo noma izingxenye zesekethe ezithintana zodwa ukuze ugweme izingozi ezithile ezifana nesekhethi emfushane. Khona-ke, cisha umlilo wemoto yakho futhi ufake izinto zokuzivikela ukuze uzivikele uma kwenzeka kuchitheka amakhemikhali anamandla. Ngemva kwalokho, kufanele unqamule ulayini onegethivu ebhethrini lemoto yakho ukuze unqamule amandla. (2)
- Uzodinga amandla afanayo (noma ngaphezulu) e-RMS ukuze ama-tweeter akho asebenze ngevolumu ephezulu. Kulungile uma i-amplifier yakho inamandla angaphezu kwadingekayo, ngoba ngeke isetshenziswe. Ngaphezu kwalokho, ukulayisha ngokweqile ama-tweeter kungabangela umonakalo unomphela ngenxa yokutubeka kwekhoyili yezwi. Ngaphezu kwalokho, nakuba i-amplifier okungenani enama-watts angu-50 i-RMS isiteshi ngasinye ilungile, ngincoma okungenani ama-watts angu-30. Ngokuvamile akufanelekile ukuzihlupha ngesikhulisamandla esinamandla aphansi ngoba izitiriyo zemoto zidonsa kuphela ama-watts angu-15-18 esiteshini ngasinye, okungekuningi kangako.
- Ukuze uzuze umsindo ozungezile omuhle, udinga ukufaka okungenani ama-tweeter amabili. Ama-tweeter amabili alungile kubantu abaningi, kodwa uma ufuna ukuthi umsindo wemoto yakho uvele ezindaweni eziningana emotweni yakho, ungase unqume ukufaka okwengeziwe.
