Subwoofer y'imodoka ni iki?
Subwoofer y'imodoka ni igice cy'ingenzi muri sisitemu y'amajwi y'imodoka, ikaba ishinzwe cyane cyane kongera amajwi afite umurongo wo hasi (ubusanzwe kuva kuri 20Hz kugeza kuri 250Hz). Inshingano yayo nyamukuru ni uguhindura ibimenyetso by'ikoranabuhanga mu majwi afite umurongo wo hasi kugira ngo hagaragazwe ingaruka za bass nk'ingufu, bass, na moteri, bikongera uburyo amajwi y'umuziki cyangwa filime akoreshwa mu gucuranga no kuyashyira mu mwanya wayo.Youdaoplaceholder0 Mu bijyanye n'imiterere n'ihame ry'imikorere, indangururamajwi y'imodoka igizwe n'imbaraga za electromagnetic (nk'ingufu za magnetism, coils z'amajwi), sisitemu yo guhindagura ibyuma (nk'inyunganiramiterere, waves z'impeshyi), na sisitemu yo gushyigikira frame. Ikora imbaraga za magnetic binyuze mu kuyobora coil y'amajwi mu mpinduka z'amashanyarazi, ibyo bigatuma diaphragm ihinda umushyitsi kandi igasunika umwuka kugira ngo utange amajwi. Akenshi ikoresha uduce duto tw'impapuro n'uduce dukomeye tw'amajwi kugira ngo ihaze icyifuzo cy'ubwinshi bunini bw'ingufu nke, byuzuza tweeter (ishinzwe igice cy'ingufu nyinshi).
Muri sisitemu y'amajwi y'imodoka, aho subwoofer ishyirwa (nk'uko biri ku muryango w'imodoka, hepfo cyangwa mu kabati kabigenewe) bizagira ingaruka ku mbaraga n'imiterere y'aho bass iherereye. Bitewe n'ibiciro bike, sisitemu y'amajwi y'imodoka ya mbere akenshi iba ifite indangururamajwi zuzuye gusa, bigatuma bass ntoya. Gushyiramo subwoofer yabigenewe bishobora kunoza cyane uburyo bwo kumva. Akenshi ikorana na crossover cyangwa ishyirwa muri subwoofer kugira ngo yongere ingaruka nziza cyane ku marangamutima.
Subwoofer iri mu modoka ni igice kiri muri sisitemu y'amajwi ishinzwe by'umwihariko kongera amajwi afite umurongo wo hasi (ubusanzwe kuva kuri 20Hz kugeza kuri 200Hz). Inshingano yayo y'ingenzi ni ukongera uburyo bwo gusubiza amajwi afite umurongo wo hasi, bigatuma amajwi y'umuziki na filime arushaho kuba meza kandi anyura mu buryo butangaje.
Iyi subwoofer ishobora kongera cyane uburyo bwo kumva . Mu kongeramo ibintu bifite umurongo muto nka drumbeat na bass, bituma injyana irushaho kuba nziza kandi ikirere kikarushaho kuba cyiza. Cyane cyane iyo ucuranga umuziki wa elegitoroniki cyangwa filime z'ibikorwa, ishobora gutuma wumva umeze neza kandi ukagira ingaruka.
Mu gace gafite urusaku rwinshi, indangururamajwi ya bass ishobora "gupfuka" uburyo imodoka ikoresha amajwi make. Urusaku rwa moteri n'urusaku rw'umuyaga bituruka ku modoka mu gihe ikora biba biri munsi ya 200Hz, bishobora gupfuka igice cy'umuziki gifite amajwi make. Subwoofer itwikira ayo majwi yongera umuvuduko w'amajwi make kandi igasubiza uburinganire bw'umuziki.
Mu buryo bwa tekiniki, subwoofer ikoresha diaphragm nini hamwe na sisitemu ikomeye ya rukuruzi kugira ngo itware umwuka mwinshi, yongera urwego rw'umuvuduko w'amajwi n'imiterere y'igihe gito. Gutunganya imiterere y'akabati bishobora kandi kongera ubwiyongere bw'umuvuduko muto, bigatuma bass yuzuye.
Ikosa rya subwoofer y'imodoka rishobora guterwa n'ibintu bitandukanye. Ibi bikurikira bitanga ibitekerezo byo gukemura ibibazo n'ibisubizo bishingiye ku bibazo bisanzwe. Birasabwa gutangirira ku bintu byoroshye hanyuma ugakomeza gucengera buhoro buhoro.
Intambwe zo gukemura ibibazo bya Youdaoplaceholder0: Ubwa mbere, emeza urwego rw'ikosa hanyuma urebe niba sisitemu yose y'ihoni ry'imodoka ikora nabi cyangwa igice cya bass gusa ari kibi. Igenzura ry'imiyoboro ya Youdaoplaceholder0 rikubiyemo:
Reba niba fuse yarahutse (urugero, fuse ya HORN ya BYD F3 iri mu gasanduku k'ibumoso ka fuse y'inzu y'umushoferi, kanditseho "Horn", gafite umuvuduko wa 15A). Niba yarahutse, igomba gusimburwa kandi hagasuzumwa icyateye uruziga rugufi.
Reba niba ibyuma bya terminal by'indangururamajwi birekuye cyangwa byangiritse, hanyuma urebe neza ko plug ikomeye.
Igenzura ry'umubiri w'umuvugizi wa Youdaoplaceholder0 rishobora gukorwa mu buryo bukurikira:
Pima ubukana bw'imirongo y'indangururamajwi ukoresheje multimeter. Igipimo gisanzwe ni hagati ya ohms 3 na 5. Iyo igaragaje ubuziraherezo (OL), coil y'imbere ishobora gushya.
Kanda ufate buto y'ihoni igihe kirekire, kandi wumve neza ihoni kugira ngo urebe niba hari ijwi rya "tap-tap". Niba nta ijwi ririho, bigaragaza ko ihoni ryangiritse kandi rigomba gusimbuzwa. Niba nta ijwi ririho, ibande ku kugenzura imikorere y'urusobe rw'amajwi.
Mu gihe ugenzura umurongo n'ibintu byo hanze, ibuka:
Reba niba insinga zarashaje, zangiritse cyangwa zifite aho zihuriye neza, cyane cyane imashini ikoresha isaha (hairspring) munsi y'uruziga rw'imodoka, ishobora kwangirika bitewe no kuzunguruka kenshi.
Irinde gukoresha imbunda y'amazi neza ku ihoni mu gihe woza imodoka kugira ngo wirinde ko amazi yinjiramo agatera ingese.
Imiterere ya sisitemu y'amajwi ya Youdaoplaceholder0 n'ibijyanye no kubungabunga umwuga:
Hindura uburyo bwo gupima amajwi kugira ngo urebe neza ko ijwi rya bass ritazimye cyangwa ngo ribe hasi cyane.
Iyo hari ikibazo gikekwa kuri amplifier y'amashanyarazi cyangwa subwoofer, hakenewe ibikoresho by'umwuga kugira ngo hagenzurwe umusaruro w'amashanyarazi.
Niba ikibazo kigikomeje nyuma yo kwisuzuma, ni byiza kuvugana n'abakozi b'inzobere mu kubungabunga kugira ngo hirindwe ko habaho kwangirika gukomeye guterwa no kubagwa mu buryo bw'amaso.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
