Subwoofer y'imodoka: Ishingiro ry'Ifunguro ry'Amajwi n'Ubuyobozi bwo Gukemura Ibibazo
Mu isi y'amajwi yo mu modoka, subwoofer imeze nk'intwari yo mu cyumba cyo hanze yicisha bugufi ariko ikenewe cyane. Ifite ijwi ryayo ryimbitse kandi risobanutse neza, ishyiraho urufatiro rwa buri ndirimbo, yongera uburyo bwo kumva bushimishije kandi bugezweho ku bagenzi.
Akamaro k'ingenzi ka subwoofer y'imodoka
Subwoofer ishinzwe cyane cyane kongera amajwi ari mu cyiciro cya 20Hz - 250Hz. Iyi frequence band ifite uburemere n'umuvuduko w'umuziki, ikaba ari ingenzi mu kubaka urusobe rw'amajwi rwuzuye. Ihindura amashanyarazi mo imiraba ya mechanical, bigatuma diaphragm inyeganyega kandi igatanga amajwi binyuze mu mwuka, ikwinjiza umuziki muri soul.
Ukurikije ubunararibonye bwo kumva, subwoofer nziza ishobora kongera cyane ishyaka n'ingaruka z'umuziki. Iyo ucuranga umuziki ukomeye nka rock cyangwa electronic, bass ikomeye ishobora gutuma ingoma zicuranga "zihamye", imirongo ya bass igaragara neza, nk'aho buri noti ishobora gukora ku mutima, bigatuma habaho umwuka wandura cyane. Mu gihe cyo kugenda mu modoka, ishobora kandi guhisha neza urusaku rw'amajwi make, nk'amajwi y'amapine n'imihanda, amajwi yo gukoresha moteri, n'ibindi, bigatuma abagenzi bishimira umuziki ahantu hatuje.
Ukurikije amahame y’amajwi, indangururamajwi zisanzwe zigengwa n’ingano n’imiterere yazo kandi zigorwa no kongera kuvuza amajwi make afite uburebure bw’umurambararo. Ariko, subwoofers, zifite diaphragms nini, impande zoroshye zo guhagarara, hamwe n’imirongo ikomeye ya magnetic circuits, hamwe n’ingomero z’inzugi z’imodoka cyangwa ahantu habigenewe, zishobora gutuma habaho ihindagurika ry’umuvuduko mu kirere. Ugutwi k’umuntu ni ko gatuma umuntu yumva neza uburebure bwa 80 - 120Hz, buzana uburemere bw’indirimbo z’ingoma n’ukuri kwa bass, iyo bitabayeho, umuziki waba nk’inyubako idafite umusingi, ndetse n’indiri isobanutse neza yasa n’aho ari nto kandi idafite ishingiro.
Amakosa asanzwe ya subwoofers z'imodoka n'uburyo bwo gukemura ibibazo
Nubwo subwoofer igira uruhare runini, ishobora no guhura n'amakosa atandukanye mu gihe cyo kuyikoresha. Ikunze kugaragara ni uko subwoofer idakora. Impamvu zibitera ziratandukanye, kandi nyirayo ashobora kubona impamvu nyamukuru binyuze mu gukemura ibibazo buhoro buhoro.
Impamvu ikunze gutera iki kibazo ni ikibazo cy’insinga. Insinga za subwoofer zishobora kuba zifite umuyoboro wangiritse, umuyoboro mugufi, cyangwa se zidakora neza, nk'insinga zishaje cyangwa zangiritse, cyangwa se imiyoboro ifunguye. Nyiri umuyoboro ashobora gusuzuma insinga ziri kuri subwoofer kugira ngo arebe niba hari ibimenyetso bigaragara by’ibyangiritse ku nsinga kandi niba umuyoboro ufunguye neza. Iyo habonetse ikibazo cy’insinga, gishobora gusanwa cyangwa gusimburwa uko bikenewe.
Subwoofer ubwayo ishobora no kwangirika, bigatuma inanirwa gutanga amajwi. Gukoresha igihe kirekire cyangwa ingaruka zo hanze bishobora gutuma ijwi rica, diaphragm igacika, nibindi. Nyiri subwoofer ashobora gupima agaciro k'ubudahangarwa bwa subwoofer akoresheje multimeter. Niba agaciro k'ubudahangarwa katari gasanzwe cyangwa subwoofer idakora iyo ihujwe n'ibindi bikoresho bisanzwe by'amajwi, bishobora kumenyekana ko subwoofer yangiritse kandi igomba gusimbuzwa indi nshya. Mu gihe uhitamo subwoofer nshya, witondere ibipimo byayo n'ubwiza bwayo kugira ngo urebe ko ihuye na sisitemu y'amajwi y'imodoka.
Amakosa muri amplifier y'amashanyarazi ashobora no kugira ingaruka ku mikorere isanzwe ya subwoofer. Iyo amplifier y'amashanyarazi inaniwe, ntabwo ishobora gutanga ingufu zihagije kuri subwoofer, kandi subwoofer ntizashobora gukora amajwi. Ibi bisaba abakozi b'inzobere mu gusana amajwi kugira ngo bamenye kandi basane. Ba nyir'ayo majwi ntibagomba kugerageza kuyasesa ubwabo, kuko bishobora kwangiza cyane.
Byongeye kandi, imiterere idahwitse y'amajwi n'amafishi yahujwe nabyo bishobora gutuma subwoofer idakora neza. Nyiri imodoka ashobora kubanza kureba urutonde rw'igenamiterere rya sisitemu y'amajwi y'imodoka kugira ngo yemeze niba ijwi rya subwoofer rizimye cyangwa ryashyizwe hasi cyane; hanyuma agashaka fisi ijyanye na sisitemu y'amajwi hanyuma akareba niba imeze neza. Niba ihujwe, yisimbuze fisi ifite imiterere imwe.
Ingingo z'ingenzi zo gushyiraho no kubungabunga subwoofers z'imodoka
Kugira ngo subwoofer ikomeze gukora neza, intambwe zo kuyishyiraho no kuyibungabunga ni ingenzi cyane. Mu gihe cyo kuyishyiraho, witondere kwirinda ko umwuka utemba hagati y’imbere n’inyuma, kuko bizatuma ingufu z’umuvuduko muto zibura kandi ijwi rigacika. Gukoresha ibikoresho bya EVA mu gufunga bishobora gukemura iki kibazo neza. Ni irashya kandi ifite imbaraga zo kuyishyigikira, ishobora gupfuka impande z’indangururamajwi no kuzuza icyuho, bigatuma bass ikomera kandi ikagira uburemere.
Mu gihe ukoresha buri munsi, irinde gucuranga umuziki ku ijwi rirenga igihe kirekire kugira ngo wirinde ko indangururamajwi zishaza kandi zikangirika. Muri icyo gihe, genzura buri gihe insinga z'indangururamajwi n'amaplaki kugira ngo urebe neza ko zifatanye neza. Niba imodoka inyuze mu bice byuzuye amazi cyangwa ikagenda ahantu hatose igihe kirekire, banza urebe niba indangururamajwi itose. Niba ari ngombwa, kora uburyo bwo kumisha.
Subwoofer y'imodoka ni igice cy'ingenzi cya sisitemu y'amajwi y'imodoka. Ntabwo yongera ireme ry'umuziki gusa ahubwo inazana ubunararibonye bwiza bwo kumva ku bashoferi n'abagenzi. Gusobanukirwa imikorere yayo, kumenya uburyo bwo gukemura ibibazo bisanzwe, no gukora akazi keza mu gushyiraho no kubungabunga bishobora gutuma subwoofer iguma mu buryo bwiza igihe cyose, byongeramo indirimbo nziza kuri buri rugendo.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
