Indangururamajwi zo mu modoka zikora neza cyane: Uburyo bwiza bwo kwita ku nshingano no gukemura ibibazo
Mu "ngoma y'amajwi" y'imodoka, indangururamajwi ifite umurongo munini nta gushidikanya ko ari "umupfumu w'amakuru arambuye". Intera y'amajwi amatwi y'abantu ashobora kubona iri hagati ya 20Hz na 20kHz. Indangururamajwi zifite umurongo wo hagati zikunze kugorwa no kongera gukoresha neza amajwi yoroshye ari hejuru ya 10kHz, ariko indangururamajwi ifite umurongo munini yagenewe by'umwihariko kuziba iki cyuho. Yeguriwe gusubiza ibimenyetso bifite umurongo munini, aho umurongo munini uherereye hagati ya 5KHz na 20KHz, kandi ishobora kwerekana neza amajwi y'ibikoresho bya muzika, uburyo amajwi y'abantu ahumeka, n'uburyo ibicurangisho by'imirya biryoshye, bigatuma uburyo bwo kumva umuziki burushaho kuba bwiza kandi bukagira icyerekezo kimwe. Iyo indangururamajwi ifite umurongo munini idahari, umuziki waba nk'umubiri udafite roho, wumvikana nk'udasobanutse kandi udasobanutse, kandi ushobora gutakaza imbaraga zawo zo gutandukanya amajwi iyo utwaye imodoka ku muvuduko mwinshi.
Mu buryo bw'imiterere, indangururamajwi zo mu modoka zikoresha ikoranabuhanga ryinshi zigizwe ahanini n'ubwoko bwa dome, zigabanyemo dome nziza n'indi negative dome units. Dome nziza ifite inguni nini igororotse, ituma agace kanini imbere mu modoka kabasha kumva neza utuntu duto tw'amajwi; dome mbi ifite inguni ntoya y'imirasire itambitse ariko ifite ubwiza bw'amajwi kandi ishobora guhangana n'imbaraga nyinshi… Ibikoresho bya diaphragm bigira ingaruka zitaziguye ku miterere y'amajwi. Dome ikomeye (alloy ya aluminiyumu, alloy ya titanium, nibindi) ifite ubushobozi bukomeye bwo kwerekana neza amajwi ya pop na filime; dome yoroshye (film ya silikoni, filime ya silikoni) ifite ubwiza bw'amajwi yoroshye kandi ihuye neza n'umuziki wa kera n'amajwi…
Aho amajwi ashyirwa ni ingenzi cyane kugira ngo amajwi akoresha amajwi menshi akore neza. Kugira ngo amajwi akoreshwe neza, akenshi ashyirwa ku nkingi ya A, hejuru y'ikibaho, cyangwa ku muryango w'imodoka. Iyi miterere ituma amakuru akoresha amajwi menshi yoherezwa mu gutwi nta gihombo, bigatuma imbere mu modoka hasa n'aho ari mu cyumba gito cy'ibitaramo. Ba nyir'imodoka benshi bashobora guhindura burundu uburyo bw'amajwi bw'imodoka bw'umwimerere bongeramo amajwi abiri ya silk membrane. Amajwi ya violon agenda agaragara neza, kandi ijwi ry'abagore risa neza imbere y'amatwi yabo. Uburyo bwo gucengera no kwinjiriramo burushaho kwiyongera.
Ariko, iyi "sosiyete itanga ubuziranenge bw'amajwi" ishobora no guhura n'ibibazo by'imikorere mibi, ibibazo bikunze kugaragara birimo kutagira amajwi, amajwi adasobanutse neza, ijwi rito cyane cyangwa urusaku rw'inyuma, nibindi. Kugira ngo ikibazo gikemuke, intambwe ya mbere ni ugusuzuma neza impamvu nyamukuru y'iyo mikorere mibi.
Niba indangururamajwi ifite ijwi rirenga idasobanutse, ushobora gukemura ikibazo ukurikije urukurikirane rwa "amashanyarazi - guhuza - imiterere - ibikoresho". Ubwa mbere, reba niba uruziga rw'amajwi rwahumetse, kandi niba ibyuma bihuza amashanyarazi birinzwe kandi nta ngese; hanyuma, genzura insinga za RCA lily-head n'insinga z'indangururamajwi kugira ngo urebe niba zidafunguye cyangwa zarangiritse, kandi urebe niba igice cy'indangururamajwi cy'umuryango cyacitse bitewe no gufungura no gufunga kenshi k'umuryango; hanyuma, menya niba ingano y'iyakira amajwi ari zeru, niba switch idafunguye iriho, kandi niba uburyo bwo gusohora butashyizweho neza; amaherezo, koresha multimeter kugira ngo upime ubukana bw'indangururamajwi. Intera isanzwe igomba kuba 3.2 - 4.5 Ω. Niba igipimo kigaragaza ubuziraherezo cyangwa kiri hafi ya 0 Ω, bigaragaza ko igice cy'indangururamajwi cyangiritse.
Iyo ijwi rigoramye cyangwa hari urusaku, birashoboka cyane ko indangururamajwi ubwayo ifite ikibazo. Kwangirika kwa diaphragm ni impamvu ikunze kugaragara. Diaphragm y'indangururamajwi ifite umurongo munini iba nto kandi ishobora kwangirika bitewe n'ingaruka zo hanze cyangwa ubushyuhe bwinshi. Kwangirika guto gushobora gusanwa hakoreshejwe kole y'indangururamajwi yabigize umwuga, ariko kwangirika gukomeye bisaba gusimbuza diaphragm. Ni byiza ko byakorwa n'inzobere kugira ngo ishyirweho neza. ^ Gucika intege cyangwa guhagarara k'uruziga rw'ijwi nabyo bishobora gutera amajwi adasanzwe. Gupima agaciro k'ubudahangarwa ukoresheje multimeter bishobora gufasha kumenya ibi. Gusimbuza indangururamajwi bisaba ubuhanga buhanitse cyane, kandi ni byiza no kuyijyana mu iduka ry'inzobere. ^ Byongeye kandi, insinga zirekuye, gukora nabi, cyangwa kubangamirana nabyo bishobora gutera urusaku mu ijwi rifite umurongo munini. Suzuma witonze imirongo yo guhuza, usukure aho ihuza, kandi usimbuze imirongo yangiritse niba bibaye ngombwa.
Hari kandi amakosa amwe n'amwe avuka rimwe na rimwe. Ibi ahanini bifitanye isano no guhuza imirongo. Urugero, guhuza nabi kw'insinga, kudakora neza kw'amakuru akoreshwa mu gukurura indangururamajwi, cyangwa ibibazo bya relay na control units. Imiterere ya buri murongo w'itumanaho n'imiterere yawo bigomba kugenzurwa kimwe kimwe. Hari igihe ibice bireba bigomba gusimburwa.
Gutunganya buri gihe bishobora kongera igihe cyo kubaho cy'indangururamajwi ifite ijwi rirenga. Irinde gucuranga ku ijwi rirenga igihe kirekire kugira ngo wirinde ko indangururamajwi ziremereye; mu gihe usukura imbere, ntugatere amazi kuri sisitemu y'amajwi; koresha igitambaro cyumye cyangwa agatambaro kabigenewe ko guhanagura umukungugu, hanyuma ukingure amadirishya kugira ngo amazi ashire; genzura buri gihe imiyoboro y'insinga kugira ngo urebe neza ko nta gucika cyangwa ingese.
Nubwo indangururamajwi nini y'imodoka ari nto, ni "idirishya ry'umutima" ry'urusobe rw'amajwi. Gusobanukirwa imikorere yayo no kumenya uburyo bwo gukemura ibibazo no kubungabunga bishobora kwemeza ko buri ndirimbo icurangwa imbere mu modoka isobanutse neza kandi ishimishije, bigatuma urushaho kwishimira kumva mu rugendo rwo gutwara imodoka.
Niba ushaka kumenya byinshi, komeza usome izindi nkuru kuri uru rubuga!
Duhamagare niba ukeneye ibyo bicuruzwa.
