Ukuxhumeka okufanele nokufakwa kwe-tweeter
Okuqukethwe
⭐ ⭐ ⭐ ⭐ ⭐ Enqubweni yokufaka isistimu yesipikha esisha, umnikazi angase abe nomsebenzi olandelayo - indlela yokuxhuma ama-tweeter (ama-tweeters) ukuze asebenze kahle futhi ngaphandle kwezinkinga?
Ingqikithi yodaba ubunkimbinkimbi bedivayisi yezinhlelo zesimanje zestereo. Ngenxa yalesi sizathu, ekusebenzeni, kunezimo lapho ama-tweeters afakiwe esebenza ngokuhlanekezela noma engasebenzi nhlobo. Ngokunamathela emithethweni yokufaka, ungagwema ubunzima obungenzeka - inqubo izoba ngokushesha futhi ibe lula ngangokunokwenzeka.
Yini i-tweeter?
Ama-tweeter esimanje awuhlobo lomthombo womsindo umsebenzi wawo uwukukhiqiza kabusha ingxenye yamafrikhwensi aphezulu. Ngakho-ke, babizwa kanjalo - izikhulumi eziphezulu-frequency noma ama-tweeters. Kumele kuqashelwe ukuthi, ukuba nosayizi ohlangene kanye nenjongo ethile, ama-tweeter kulula ukuyifaka kunezipikha ezinkulu. Zikhiqiza umsindo oqondisayo, futhi kulula ukuzibeka ukuze zenze imininingwane yekhwalithi ephezulu kanye nokuvezwa okunembile kwebanga lomsindo, okuzozwiwa umlaleli ngokushesha.
Kunconywa kuphi ukufaka ama-tweeter?
Abakhiqizi batusa izindawo eziningi lapho ama-tweeter angabekwa khona, ngokuvamile ezingeni lendlebe. Ngamanye amazwi, zibhekise phezulu ngangokunokwenzeka kumlaleli. Kodwa akubona bonke abavumelana nalo mbono. Lesi silungiselelo akulula ngaso sonke isikhathi. Kuya ngezimo ezithile. Futhi inani lezinketho zokufaka likhulu impela.
Isibonelo:
- Amakhona esibuko. Phakathi nohambo, ngeke babangele ukungakhululeki okwengeziwe. Ngaphezu kwalokho, zizongena kahle ngaphakathi kwemoto;
- Ideshibhodi. Ukufakwa kungenziwa ngisho nange-tape enezinhlangothi ezimbili;
- Izinkundla. Kunezinketho ezimbili lapha. Eyokuqala ukubeka ama-tweeter endaweni evamile (efika ne-tweeter), okwesibili ukwenza i-podium ngokwakho. Icala lakamuva liyinkimbinkimbi kakhulu, kodwa liqinisekisa umphumela ongcono.
Ikuphi indawo engcono kakhulu yokuthumela ama-tweeters?
Lapho uklama umsindo wemoto, ungakhetha eyodwa kwezimbili ongakhetha kuzo:
- i-tweeter ngayinye iqondiswe kumlaleli. Okungukuthi, i-squeaker efanele ithunyelwa kumshayeli, ngakwesobunxele - futhi kuye;
- ukulungiselelwa kwe-diagonal. Ngamanye amazwi, i-tweeter engakwesokudla iqondiswe esihlalweni esingakwesokunxele, kuyilapho isipikha esingakwesokunxele sihanjiswa kwesokudla.
Ukukhethwa kwenketho eyodwa noma enye kuncike kulokho okuthandwa ngumnikazi. Okokuqala, ungaqondisa ama-tweeter kuwena, bese uzama indlela ye-diagonal. Ngemuva kokuhlolwa, umnikazi ngokwakhe uzonquma ukuthi akhethe indlela yokuqala, noma anikeze okuthandayo kwesibili.
Izici Zokuxhuma
I-tweeter iyingxenye yesistimu ye-stereo umsebenzi wayo uwukukhiqiza kabusha umsindo ovela ku-3000 kuya ku-20 hertz. Isiqophamazwi somsakazo sikhiqiza uhla olugcwele lwamaza, asukela kuma-hertz amahlanu kuya ku-000 hertz.
I-tweeter ingakwazi ukukhiqiza kabusha umsindo wemoto kuphela nge-frequency ye-hertz eyizinkulungwane ezimbili. Uma isignali ye-low-frequency isetshenziswa kuyo, ngeke idlale, futhi ngamandla amakhulu ngokwanele lapho izikhulumi ze-mid- and low-frequency ziklanyelwe khona, i-tweeter ingase yehluleke. Ngesikhathi esifanayo, angeke kube khona umbuzo wanoma iyiphi ikhwalithi yokudlala. Ukuze usebenze isikhathi eside futhi onokwethenjelwa kwe-tweeter, kufanele ulahle izingxenye ze-low-frequency ezikhona ku-spectrum jikelele. Okungukuthi, qiniseka ukuthi kuphela ibanga lefrikhwensi yokusebenza elinconyiwe eliwela kulo.
Indlela yokuqala futhi elula yokusika ingxenye ye-low-frequency ukufaka i-capacitor ochungechungeni. Idlula kahle ibhendi yefrikhwensi ephezulu, iqala ku-hertz eyizinkulungwane ezimbili nangaphezulu. Futhi ayidluli amafrikhwensi angaphansi kuka-2000 Hz. Eqinisweni, lesi isihlungi esilula kunazo zonke, amathuba awo anomkhawulo.
Njengomthetho, i-capacitor isivele ikhona ohlelweni lwesipika, ngakho-ke ayidingi ukuthengwa ngaphezu kwalokho. Kufanele ucabange ngokuyithenga uma umnikazi enquma ukuthola umsakazo osetshenzisiwe, futhi akazange athole i-capacitor kukhithi ye-tweeter. Kungase kubukeke kanje:
- Ibhokisi elikhethekile lapho kufakwa khona isiginali bese lidluliselwa ngqo kuma-tweeters.
- I-capacitor ifakwe ocingweni.
- I-capacitor yakhelwe ngqo ku-tweeter ngokwayo.
Uma ungabonanga noma yiziphi izinketho ezisohlwini, kufanele uthenge i-capacitor ngokwehlukana bese uyifaka ngokwakho. Ezitolo zomsakazo, i-assortment yabo inkulu futhi ihlukahlukene.
Ibanga lefrikhwensi elihlungiwe lincike ohlotsheni lwe-capacitor efakiwe. Isibonelo, umnikazi angafaka i-capacitor ezokhawulela i-frequency range enikezwa ezipikhani ibe izinkulungwane ezintathu noma ezine ze-hertz.
Qaphela! Ukuphakama kwemvamisa yesiginali esetshenziswa ku-tweeter, imininingwane yomsindo ingafinyelelwa.
Ebukhoneni besistimu yezindlela ezimbili, ungenza ukukhetha ngokuthanda ukunqanyulwa kwe-hertz eyizinkulungwane ezimbili kuya kwezine nengxenye.
I-Подключение
Uxhumano lwe-tweeter lumi kanje, luxhunywe ngqo kusipika esitholakala emnyango wakho, kanye ne-tweeter ixhunywe ku-plus yesipika kanye nokukhipha ku-minus, kuyilapho i-capacitor kufanele ixhunywe ku-plus. Ukuze uthole imininingwane eyengeziwe ngokuthi yimuphi umbala wentambo ofanele ukuthi iyiphi ikholomu, bheka umdwebo wokuxhumana nomsakazo. Lesi iseluleko esisebenzayo kulabo abangakwazi ukuxhuma ama-tweeter ngaphandle kwe-crossover.
Enye inketho yokuxhuma ukusebenzisa i-crossover. Kwamanye amamodeli wezinhlelo zesipika zezimoto, isivele ifakiwe kukhithi. Uma ingatholakali, ungayithenga ngokwehlukana.
Ezinye izici
Kuze kube manje, inketho ye-tweeter ejwayelekile kakhulu uhlelo lwe-electrodynamic. Ngokwesakhiwo, siqukethe indlu, uzibuthe, ikhoyili ene-winging, i-diaphragm ene-membrane nezintambo zamandla ezinamatheminali. Lapho kusetshenziswa isignali, kugeleza okwamanje kukhoyili, kwakheka inkambu ye-electromagnetic. Isebenzisana nozibuthe, ukudlidliza kwemishini kwenzeka, okudluliselwa ku-diaphragm. Lesi sakamuva sidala amagagasi e-acoustic, umsindo uzwakala. Ukuze kuthuthukiswe ukusebenza kahle kokukhiqizwa komsindo, ulwelwesi lunomumo othile wedome. Ama-tweeter emoto ngokuvamile asebenzisa ulwelwesi lukasilika. Ukuze uthole ukuqina okwengeziwe, i-membrane ifakwe inhlanganisela ekhethekile. Usilika ubonakala ngokukwazi ukubhekana ngokuphumelelayo nemithwalo ephezulu, ukushintsha kwezinga lokushisa kanye nomswakama.Kuma-tweeters abiza kakhulu, ulwelwesi lwenziwe nge-aluminium encane noma i-titanium. Ungahlangabezana nalokhu kuphela kumasistimu e-acoustic ahlonishwa kakhulu. Kusistimu yomsindo wemoto evamile, zivela kancane.
Inketho eshibhile i-membrane yephepha.
Ngaphezu kokuthi umsindo ubi kakhulu kunamacala amabili adlule, imishini enjalo inokuphila okufushane kakhulu kwenkonzo. Futhi lokhu akumangazi, ngoba iphepha alikwazi ukunikeza ukusebenza kwekhwalithi ephezulu ye-tweeter ezimweni zokushisa okuphansi, amazinga aphezulu omswakama nomthwalo ophezulu. Lapho umshini unyusa isivinini senjini, kungase kuzwakale umsindo ongaphandle.
Ungakhohlwa ukuthi ungakwazi futhi ukusetha i-buzzer usebenzisa umsakazo. Ngisho namamodeli ashibhe kakhulu anekhono lokulungisa amaza aphezulu. Ikakhulukazi, amamodeli webanga lentengo eliphakathi ane-equalizer eyakhelwe ngaphakathi, eyenza umsebenzi ube lula kakhulu.
Ngemva kokufaka i-tweeter, udinga ukusetha isistimu yomsindo, nokuthi ungakwenza kanjani lokhu, funda isihloko esithi "Indlela yokusetha umsakazo".
