Waba urimo gucuranga ingoma mu modoka yawe, ushyiraho sisitemu yo kureba filime nshya ya Avengers, cyangwa se urimo kubaka sisitemu ya stereo y'itsinda ryawe, ushobora kuba ushaka iyo bass yimbitse kandi iryoshye. Kugira ngo umenye iri jwi, ukeneye subwoofer.

Subwoofer ni ubwoko bw'indangururamajwi zikora bass nka bass na sub-bass. Subwoofer ifata ijwi ryoroheje ikarihinduramo amajwi subwoofer idashobora gukora.

Iyo sisitemu yawe y'indangururamajwi iteguye neza, ushobora kumva amajwi yimbitse kandi yuzuye. Subwoofer ikora ite? Ni izihe subwoofer nziza kurusha izindi, kandi se koko zigira ingaruka zikomeye kuri sisitemu yawe y'indangururamajwi muri rusange? Dore ibyo ukeneye kumenya.

Ni ikisubwoofer?

Niba ufite subwoofer, hagomba kuba hari indi subwoofer imwe, sibyo? Nibyo. Inyinshi muri woofers cyangwa indangururamajwi zisanzwe zishobora gukora amajwi agera kuri 50 Hz gusa. Subwoofer itanga amajwi make kugeza kuri 20 Hz. Bityo, izina "subwoofer" rikomoka ku gutontoma guke imbwa zikora iyo zitontomye.

Nubwo itandukaniro riri hagati y’umuvuduko wa 50 Hz w’indangururamajwi nyinshi n’umuvuduko wa 20 Hz wa subwoofer rishobora kumvikana nk’aho ridafite agaciro, ibisubizo biragaragara. Umuvuduko wa subwoofer ugufasha kumva ijwi rya bass mu ndirimbo no muri filime, cyangwa ikindi kintu cyose uri kumva. Uko umuvuduko wa subwoofer ugabanuka, niko umuvuduko wa bass uba ukomeye kandi uryoshye.

Kubera ko aya majwi ari make cyane, hari abantu badashobora no kumva ijwi rya basi riva kuri subwoofer. Niyo mpamvu igice cy'ibyiyumvo cya subwoofer ari ingenzi cyane.

Amatwi akiri mato kandi afite ubuzima bwiza ashobora kumva amajwi ari hasi cyane kugeza kuri Hz 20, bivuze ko amatwi y’abantu bo mu kigero cyo hagati rimwe na rimwe agorana kumva amajwi yimbitse cyane. Ukoresheje subwoofer, nta gushidikanya ko uzumva ijwi rihindagurika nubwo utabyumva.

Subwoofer ikora ite?

Iyi subwoofer ihuzwa n'izindi ndangururamajwi ziri muri sisitemu y'amajwi yuzuye. Niba ucuranga umuziki mu rugo, ushobora kuba ufite subwoofer ihujwe n'iyakira amajwi yawe. Iyo umuziki ucurangwa binyuze muri za ndangururamajwi, yohereza amajwi yo hasi kuri subwoofer kugira ngo ayikore neza.

Ku bijyanye no gusobanukirwa uburyo subwoofers zikora, ushobora guhura n'ubwoko bwa active na passive. Active subwoofer ifite amplifier yubatswemo. Passive subwoofers zikenera amplifier yo hanze. Niba uhisemo gukoresha active subwoofer, uzakenera kugura insinga ya subwoofer, kuko uzagomba kuyihuza na receiver ya sisitemu y'amajwi, nk'uko byasobanuwe haruguru.

Uzabona ko muri sisitemu y'amajwi yo mu rugo, subwoofer ari yo ndangururamajwi nini kurusha izindi. Ese nini ni nziza kurushaho? Yego! Uko indangururamajwi nini ni ko ijwi rirushaho kuba ryimbitse. Indangururamajwi nini ni zo zonyine zishobora gukora amajwi yimbitse wumva muri subwoofer.

Bite se ku bijyanye no gutigita? Ibi bikora bite? Ingufu za subwoofer ziterwa ahanini n'aho ziherereye. Injeniyeri z'inzobere mu by'amajwi zisaba gushyiraho subwoofer:

Munsi y'ibikoresho. Niba ushaka kumva ijwi ryimbitse kandi rikungahaye rya filime cyangwa umuziki, kuwushyira munsi y'ibikoresho byawe, nko kuri sofa cyangwa intebe, bishobora kongera ibyo byiyumvo.

iruhande rw'urukuta. Shyira ibyaweagasanduku ka subwooferiruhande rw'urukuta kugira ngo ijwi rizanyure mu rukuta kandi ryongere ijwi rya bass.

Uburyo bwo guhitamo subwoofer nziza kurusha izindi

Kimwe n'indangururamajwi zisanzwe, imiterere ya subwoofer ishobora kugira ingaruka ku buryo bwo kugura. Bitewe n'icyo ushaka, iki nicyo ugomba kureba.

Ingano y'Inshuro

Ijwi rito cyane rya subwoofer ni ijwi rito cyane umushoferi w’indangururamajwi ashobora gukora. Ijwi rito cyane ni ijwi rito cyane umushoferi ashobora kubona. Ijwi ryiza cyane ritanga ijwi rigera kuri 20 Hz, ariko umuntu agomba kureba aho ijwi rigera kugira ngo arebe uburyo subwoofer ihurira muri sisitemu rusange ya stereo.

Ubuhanga bwo kwiyumvisha ibintu

Mu gihe ureba imiterere ya subwoofers zikunzwe, reba uburyo bwo kumva. Ibi bigaragaza imbaraga zikenewe kugira ngo ijwi runaka rikoreshwe. Uko ubushobozi bwo kumva burushaho kuba bwinshi, ni ko imbaraga zikenewe kugira ngo ijwi rikoreshwe neza nk'iry'umuvuduko w'amajwi wo ku rwego rumwe.

Ubwoko bw'akabati

Utwuma duto duto tw’amajwi dusanzwe twubatswe mu gasanduku ka subwoofer dukunda kuguha ijwi ryimbitse kandi ryuzuye kurusha iridafite ipfundo. Agasanduku gafite icyuho ni keza ku majwi menshi, ariko ntabwo ari ngombwa ko amajwi aba menshi.

Impedance

Impedance, ipimwa muri ohms, ifitanye isano n'ubudahangarwa bw'igikoresho ku muyoboro w'amajwi unyuze mu isoko ry'amajwi. Inyinshi muri subwoofers zifite impedance ya ohms 4, ariko ushobora no kubona subwoofers za ohms 2 na ohms 8.

Koili y'ijwi

Inyinshi muri subwoofers zigira umuvuduko umwe w'ijwi, ariko abakunzi b'amajwi bafite uburambe cyangwa ishyaka bakunze guhitamo umuvuduko w'ijwi ubiri. Ukoresheje imivuduko ibiri y'ijwi, ushobora guhuza sisitemu y'ijwi uko ubyifuza.

Imbaraga

Mu gihe uhitamo subwoofer nziza, menya neza ko ureba ingufu zigenwe. Muri subwoofer, ingufu za RMS ni ingenzi cyane kuruta imbaraga zigenwe. Ibi biterwa nuko ipima imbaraga zihoraho aho gupima imbaraga zigenwe. Niba usanzwe ufite amplifier, menya neza ko subwoofer ureba ishobora kwihanganira ingufu zisohoka.
