Iyo yakakosha chikamu che condenser maikorofoni ndiyo danda remusoro, iro rinoumbwa nemafirimu maviri esimbi;Kana iyo ruzha wave ichikonzera kuzunguzika kwayo, nzvimbo yakasiyana yefirimu resimbi inokonzeresa iyo capacitance yakasiyana uye inogadzira ikozvino.Nekuti iyo danda musoro unoda imwe voltage yepolarization, condenser maikorofoni kazhinji inoda kushandisa phantom magetsi kushanda.Condenser maikorofoni ine hunhu hwekunzwa kwakanyanya uye yakakwira yakananga.Naizvozvo, inowanzoshandiswa mumimhanzi yakasiyana-siyana yehunyanzvi, firimu uye terevhizheni kurekodha, izvo zvakajairika mu studio yekurekodha.
Imwe mhando yecondenser maikorofoni inonzi electret maikorofoni.Electret maikorofoni ine hunhu hwevhoriyamu diki, yakafara frequency renji, kutendeka kwakanyanya uye mutengo wakaderera.Yakave ichishandiswa zvakanyanya mumidziyo yekutaurirana, midziyo yemumba uye zvimwe zvigadzirwa zvemagetsi.Kana maikorofoni e electret agadzirwa, iyo diaphragm yakaiswa kune yakakwira-voltage polarization kurapwa uye ichachajwa zvachose, saka hapana chikonzero chekuwedzera imwe polarization voltage.Zvekutakurika uye zvimwe zvinodiwa, electret condenser maikorofoni inogona kuitwa idiki kwazvo, saka inozokanganisa kunaka kwekurira kune imwe nhanho.Asi nedzidziso, hapafanirwe kuve nemusiyano wakawanda mumhando yekurira pakati pemakrofoni eelectret ehukuru hwakafanana uye echinyakare condenser maikorofoni anoshandiswa zvakanyanya mukurekodha studio.
Chinese zita condenser maikorofoni zita rekunze condenser maikorofoni alias condenser maikorofoni musimboti yakanyanyisa kutetepa goridhe-yakapfekwa firimu capacitor akati wandei P farad yemukati kuramba g ohm nhanho inoratidzira zvakachipa, vhoriyamu diki uye yakanyanya kunzwa.

Condenser maikorofoni
Iyo inonzwika yekupikicha musimboti wecondenser maikorofoni ndeye kushandisa yakanyanya kutetepa goridhe-yakaputirwa firimu sedanda rimwe re capacitor, rakaparadzaniswa nezvikamu zvishoma zvegumi zvemamirimita, uye imwe yakagadziriswa electrode, kuitira kuti igadzire capacitor yeP farads akati wandei.Iyo firimu electrode inoshandura huwandu hwe capacitor uye inoumba chiratidzo chemagetsi nekuda kwekudengenyeka kweizwi wave.Nekuti iyo capacitance inongova mashoma P farads, kupikisa kwayo kwemukati kwakanyanya, Svika padanho reG ohms.Naizvozvo, dunhu rinodiwa kushandura iyo G ohm impedance kuita yakajairika impedance ye600 ohm.Dunhu iri, rinozivikanwawo se "pre amplification circuit", rinowanzobatanidzwa mukati mecondenser maikorofoni uye rinoda "phantom power supply" kuti rigone dunhu.Nekuda kwekuvapo kweiyi pre amplification circuit, condenser maikorofoni inofanirwa kufambiswa nemagetsi ephantom kuti ishande zvakajairwa.Condenser maikorofoni + phantom magetsi emagetsi anowanzo kutarisisa, ayo anonyanya kunzwisiswa pane akajairika maikorofoni ane simba.Mune mamwe mazwi, iyo phantom magetsi inodiwa kuti condenser maikorofoni inyore kana ichishandiswa pamakomputa kana zvimwe zvishandiso, uye ruzha rwakarekodhwa haruzove diki pane iro remakrofoni ane simba.[1]

Iyi maikorofoni ndiyo inonyanya kufarirwa nekuti yakachipa, idiki uye inoshanda.Dzimwe nguva inonziwo maikorofoni.Nheyo chaiyo ndeyeiyi inotevera: pane yakakosha dhizaini yezvinhu, pane kubhadharisa.Mhosva pano haisi nyore kusunungura.Kana vanhu vachitaura, firimu rakachajwa rinodedera.Somugumisiro, kureba pakati payo uye imwe ndiro inogara ichichinja, zvichiita kuti kuchinja kwe capacitance.Uyewo, sezvo mutero pairi unoramba usina kuchinjwa, mhepo ichachinjawo maererano ne q = Cu, Nenzira iyi, chiratidzo chezwi chinoshandurwa kuva chiratidzo chemagetsi.Ichi chiratidzo chemagetsi chinowanzo wedzerwa kune FET mukati memaikorofoni kukwidziridza chiratidzo.Paunenge uchibatanidza kudunhu, teerera kune kwayo kwakaringana kubatana.Pamusoro pezvo, maikorofoni epiezoelectric anowanzoshandiswa mune mamwe maturusi ekupedzisira.Sezvakaratidzwa mumufananidzo 1.
Chinhu chakakosha cheiyo condenser maikorofoni ndiyo musoro wedanho, unoumbwa nemafirimu maviri esimbi;Kana iyo ruzha wave ichikonzera kuzunguzika kwayo, nzvimbo yakasiyana yefirimu resimbi inokonzeresa iyo capacitance yakasiyana uye inogadzira ikozvino.Condenser maikorofoni kazhinji inoda 48V phantom magetsi, maikorofoni amplification michina kana musanganiswa kuti ushande.
Condenser maikorofoni ndeimwe yemhando dzekare maikorofoni, iyo inogona kuteverwa kumashure kwekutanga kwezana ramakore rechi20.Kuenzaniswa nemamwe marudzi emakrofoni, iyo mechanic chimiro checondenser maikorofoni ndiyo yakapusa.Inonyanya kunama diaphragm yakatetepa yakatambanudzwa papepa resimbi rinonzi ndiro yekumashure, uye shandisa chimiro ichi kugadzira capacitor iri nyore.Wobva washandisa yekunze voltage sosi (kazhinji phantom magetsi ekupa, asi mazhinji macondenser maikorofoni anewo ega emagetsi ekushandisa) kupa simba kune capacitor.Kana dzvinyiriro yeruzha ichiita pa diaphragm, diaphragm ichaita kuzunguzika kudiki kwakasiyana-siyana pamwe neiyo waveform, uyezve vibration iyi inozoshandura inobuda voltage kuburikidza nekuchinja kwecapacitance, iyo inoumba chiratidzo chekubuda chemaikorofoni.Muchokwadi, capacitance Maikorofoni inogona zvakare kukamurwa kuita akati wandei marudzi, asi yavo yekutanga kushanda musimboti yakafanana.Parizvino, iyo inonyanya kufarirwa maikorofoni inonzi condenser ndiyo U87 inogadzirwa naNeumann.[2]

Iyo yakajairika chimiro cheiyo condenser maikorofoni inoratidzwa mumufananidzo "musimboti wecondenser maikorofoni": maviri electrode mahwendefa ecapacitor akakamurwa kuita zvikamu zviviri, izvo zvinonzi diaphragm uye kumashure electrode zvichiteerana.Single diaphragm maikorofoni danda musoro, diaphragm uye kumashure danda zviri pamativi ese zvakateerana, kaviri diaphragm pole musoro, kumashure danda riri pakati, uye diaphragm iri pamativi ese.
Kutungamira kweiyo condenser maikorofoni kunoitwa kuburikidza nekungwarira dhizaini uye debugging yeacoustic nzira kune yakatarisana neiyo diaphragm, iyo inoita basa rakakura muakasiyana ekurekodha zviitiko, kunyanya panguva imwe chete uye kurarama kurekodha.
Kazhinji kutaura (kunze kwechokwadi), maikorofoni econdenser ari pamusoro pemakrofoni ane simba mukunzwa uye akawedzera yakakwirira-frequency (dzimwe nguva yakaderera-frequency) mhinduro.
Izvi zvine chekuita nemusimboti wekushanda wekuti condenser maikorofoni inoda kushandura masaini masaini kuita azvino kutanga.Kazhinji, diaphragm yecondenser maikorofoni yakatetepa kwazvo, iri nyore kubvunda pasi pesimba rekumanikidza kwenzwi, zvichikonzera shanduko inowirirana yevoltage pakati pe diaphragm uye yekumashure backplane ye diaphragm compartment.Iyi shanduko yemagetsi inokwidziridzwa neiyo preamplifier uye yozoshandurwa kuita inobuda chiratidzo.
Ehe, iyo preamplifier yataurwa pano inoreva iyo amplifier yakavakirwa maikorofoni, pane iyo "preamplifier", kureva, preamplifier pamusanganisi kana interface.Nekuti iyo diaphragm nharaunda yecondenser maikorofoni idiki kwazvo, inonyatso nzwira kune yakaderera-frequency kana yakakwirira-frequency masaini masaini.Ichokwadi.Mazhinji macondenser maikorofoni anogona kunyatsotora masaini masaini asinganzwikwe nevanhu vazhinji.[2]
