Ihame nogukoresha mikoro ya kondenseri

Ku ya 23 Ukuboza 15:12:07 CST 2021
Ibyingenzi bigize mikoro ya kondenseri ni umutwe wa pole, ugizwe na firime ebyiri zicyuma;Iyo ijwi ryijwi ritera kunyeganyega, intera itandukanye ya firime yicyuma itera ubushobozi butandukanye kandi ikabyara amashanyarazi.Kuberako umutwe wa pole ukenera voltage runaka kugirango polarisiyasi, mikoro ya kondenseri ikenera gukoresha amashanyarazi ya fantom kumurimo.Mikoro ya condenser ifite ibiranga sensibilité yo hejuru hamwe nubuyobozi buhanitse.Kubwibyo, muri rusange ikoreshwa mumuziki itandukanye yumwuga, firime na tereviziyo byafashwe amajwi, bikunze kugaragara cyane muri studio yafata amajwi.
Ubundi bwoko bwa mikoro ya kondenseri yitwa mikoro ya electret.Mikoro ya elegitoronike ifite ibiranga ingano ntoya, intera yagutse, ubudahemuka bwinshi nigiciro gito.Yakoreshejwe cyane mubikoresho byitumanaho, ibikoresho byo murugo nibindi bicuruzwa bya elegitoroniki.Iyo mikoro ya electret yakozwe, diaphragm yakorewe imiti myinshi ya polarisiyasi kandi izajya yishyurwa burundu, ntabwo rero bikenewe kongeramo ingufu za polarisiyasi.Kubintu byoroshye nibindi bisabwa, mikoro ya electret condenser irashobora gukorwa ntoya cyane, kuburyo bizagira ingaruka kumajwi kurwego runaka.Ariko mubyukuri, ntihakagombye kubaho itandukaniro ryinshi mubyiza byijwi hagati ya mikoro ya electret ingana na mikoro gakondo ya kondenseri gakondo ikoreshwa cyane muri studio zafata amajwi.
Izina ryigishinwa condenser mikoro Izina ryamahanga kondenseri mikoro alias condenser microphone ihame ryoroshye cyane ryometse kuri zahabu capacitor ya P farad imbere irwanya imbere g ohm urwego ruhendutse, ingano nto hamwe na sensibilité nyinshi

Ihame rya pickup yijwi rya mikoro ya kondenseri ni ugukoresha firime yoroheje cyane yometseho zahabu nka pole imwe ya capacitor, itandukanijwe na kimwe cya cumi cya milimetero, nindi electrode ihamye, kugirango ikore capacitor ya faradi nyinshi P.Filime electrode ihindura ubushobozi bwa capacitor kandi ikora ikimenyetso cyamashanyarazi kubera kunyeganyega kwijwi ryijwi.Kuberako capacitance ari P faradi nkeya gusa, kurwanya imbere kwayo ni hejuru cyane, Kugera kurwego rwa G ohms.Kubwibyo, uruziga rurakenewe kugirango uhindure G ohm impedance muri rusange impedance ya 600 ohm.Uyu muzunguruko, uzwi kandi nka "pre amplification circuit", mubisanzwe winjizwa imbere muri mikoro ya kondenseri kandi ukenera "fantom power power" kugirango amashanyarazi.Kubera ko hariho uruzinduko rwambere rwa amplification, mikoro ya kondenseri igomba kuba ikoreshwa namashanyarazi ya fantom kugirango ikore bisanzwe.Mikoro ya kondereseri + amashanyarazi ya fantom muri rusange arumva cyane, aribyoroshye cyane kuruta mikoro isanzwe.Muyandi magambo, amashanyarazi ya fantom arakenewe kugirango mikoro ya kondenseri yandike niba ikoreshwa kuri mudasobwa cyangwa ibindi bikoresho, kandi amajwi yafashwe ntabwo azaba mato ugereranije na mikoro ifite imbaraga.[1]

Ubu bwoko bwa mikoro nibisanzwe kuko bihendutse, bito kandi byiza.Rimwe na rimwe nanone byitwa mikoro.Ihame ryihariye niryo rikurikira: kurwego rwihariye rwibikoresho, hari amafaranga.Amafaranga hano ntabwo yoroshye kurekura.Iyo abantu bavuga, firime yishyuzwa iranyeganyega.Nkigisubizo, intera iri hagati yacyo nisahani runaka ihora ihinduka, bikavamo ihinduka ryubushobozi.Na none, kubera ko amafaranga kuri yo adahinduka, voltage nayo izahinduka ukurikije q = Cu, Muri ubu buryo, ikimenyetso cyijwi gihinduka ikimenyetso cyamashanyarazi.Iki kimenyetso cyamashanyarazi muri rusange cyongewe kuri FET imbere muri mikoro kugirango yongere ibimenyetso.Mugihe uhuza umuzunguruko, witondere guhuza kwayo.Mubyongeyeho, mikoro ya piezoelectric nayo ikoreshwa mubikoresho bimwe na bimwe byo hasi.Nkuko bigaragara ku gishushanyo 1.
Ibyingenzi bigize mikoro ya kondenseri ni umutwe wicyiciro, ugizwe na firime ebyiri zicyuma;Iyo ijwi ryijwi ritera kunyeganyega, intera itandukanye ya firime yicyuma itera ubushobozi butandukanye kandi ikabyara amashanyarazi.Mikoro ya kondereseri ikenera amashanyarazi ya 48V ya fantom, ibikoresho byongera mikoro cyangwa mixer kugirango ikore.
Mikoro ya kondereseri ni bumwe mu bwoko bwa mikoro ya kera, ishobora kuva mu ntangiriro z'ikinyejana cya 20.Ugereranije nubundi bwoko bwa mikoro, imiterere yubukorikori bwa mikoro ya condenser niyo yoroshye.Nubusanzwe gushira pasitoro yoroheje irambuye ya diafragma kurupapuro rwicyuma rwitwa plaque yinyuma, hanyuma ugakoresha iyi miterere kugirango ukore capacitor yoroshye.Noneho koresha voltage yo hanze (mubisanzwe itanga amashanyarazi, ariko mikoro myinshi ya kondenseri nayo ifite ibikoresho byayo bitanga amashanyarazi) kugirango utange ingufu kuri capacitor.Iyo umuvuduko wijwi ukora kuri diaphragm, diaphragm izakora ibintu bitandukanye byinyeganyeza bito hamwe na flimform, hanyuma uku kunyeganyega bizahindura imbaraga ziva mumashanyarazi binyuze mumihindagurikire ya capacitance, igizwe nikimenyetso gisohoka cya mikoro.Mubyukuri, capacitance Microphone nayo irashobora kugabanwa muburyo butandukanye, ariko ihame ryibanze ryakazi ni rimwe.Kugeza ubu, mikoro ikunzwe cyane ni U87 yakozwe na Neumann.[2]

Imiterere rusange ya mikoro ya kondenseri yerekanwa ku gishushanyo “ihame rya mikoro ya kondenseri”: amasahani abiri ya electrode ya capacitor agabanijwemo ibice bibiri, aribyo bita diaphragm na electrode yinyuma.Diaphragm imwe ya mikoro ya pole umutwe, diaphragm na pole yinyuma biherereye kumpande zombi, umutwe wa diaphragm pole umutwe, inkingi yinyuma iherereye hagati, na diaphragm iherereye kumpande zombi.
Ubuyobozi bwa mikoro ya kondenseri ikorwa hifashishijwe igishushanyo mbonera no gukemura inzira ya acoustic kuruhande rwa diaphragm, igira uruhare runini mubihe bitandukanye byafashwe amajwi, cyane cyane icyarimwe kandi byafashwe amajwi.
Muri rusange tuvuze (usibye ko byanze bikunze), mikoro ya kondenseri iruta mikoro ifite imbaraga mu kwiyumvisha ibintu no kwagura ibisubizo byinshi (rimwe na rimwe bikabije).
Ibi bifitanye isano nihame ryakazi ko mikoro ya kondenseri ikeneye guhindura ibimenyetso byamajwi mubyambere.Mubisanzwe, diaphragm ya mikoro ya kondenseri iroroshye cyane, byoroshye kunyeganyega bitewe numuvuduko wamajwi, bikavamo ihinduka rihuye ryumuvuduko uri hagati ya diafragma ninyuma yinyuma yibice bya diaphragm.Ihinduka rya voltage rizongerwaho na preamplifier hanyuma rihindurwe amajwi yerekana amajwi.
Birumvikana ko preamplifier yavuzwe hano yerekeza kuri amplifier yubatswe muri mikoro, aho kuba "preamplifier", ni ukuvuga preamplifier kuri mixer cyangwa interineti.Kuberako agace ka diaphragm ya mikoro ya kondenseri ari nto cyane, irumva cyane ibimenyetso byamajwi cyangwa amajwi menshi.Ni ukuri.Mikoro nyinshi ya kondenseri irashobora gufata neza ibimenyetso byamajwi abantu benshi badashobora kumva.[2]
Intego yo guhindura ibiganiro
Mikoro ya Condenser ni mikoro nziza yo gufata amajwi.Mu mikoreshereze yacyo harimo solo, saxofone, umwironge, umuyoboro wibyuma cyangwa inkwi, gitari acoustic cyangwa bass acoustic.Mikoro ya kondereseri ikwiranye nahantu hose hasabwa ubuziranenge bwijwi ryiza nijwi.Bitewe nuburyo bukomeye hamwe nubushobozi bwo guhangana numuvuduko mwinshi wamajwi, mikoro ya kondenseri niyo nzira nziza yo gushimangira amajwi nzima cyangwa gufata amajwi.Irashobora gufata ingoma y'ibirenge, gitari na disikuru ya bass.[3]
