Electret maikorofoni

Electret maikorofoni mufananidzo condenser mamaikorofoni. Kazhinji, mamaikorofoni izvi zvinoshandiswa Studios basa, asi zvingave akakodzera mudzidzi zvinangwa. Kazhinji, asi capacitor electret mamaikorofoni aiwanzoshandisa kushongedzera musha yakarekodwa Studio.

Pamisika ano Russian angawana guru zvakawanda zvokushandisa. Pakati ano vaitaura vanogona kusarudza electret maikorofoni, vose vatorwa uye mumhuri kugadzirwa. Kana isu kutaura pamusoro mutengo nenyaya, gudzanzwi vemamwe kugadzirwa anodhura kupfuura Russian. Kazhinji, uku kuwedzera mitengo haaruramiswi zvikuru sezvo electret maikorofoni Russian kugadzirwa hakusi vakaderera unhu kune dzimwe vaya.

Parizvino mamaikorofoni kushanda kwaidarika ichi mhando mamaikorofoni vane yakasiyana kugadzira. Chikonzero ndechokuti panguva yakaderera chaizvo mutengo electret maikorofoni kunoratidzwa yakakwirira kuvimbwa, pasi uremu uye sandara Frequency mhinduro.

Mamaikorofoni kwakadai capacitors, zvimwe izvo ndiro wakaumbwa nhete chaizvo firimu wakatambanudzwa pamusoro rin'i. Plastic firimu iri irradiated ane danda kubva maerekitironi kuti kupinda muduku kudzika, uye somugumisiro kusika chinhambwe mutariri ane kugona kuponesa refu.

In kwakadai insulators vane zita "electret" - kuti maikorofoni iri anonzi electret.

Zvadaro seari pamusoro firimu iri zvakakwana marata layer rinoshandiswa somumwe electrodes. Somumwe electrode makabuda simbi humburumbira, ane planar pemvura iri pedyo firimu.

Its oscillations izvo zvinokonzerwa acoustic namafungu, anokwanisa rakasikwa magetsi pakati electrodes. Nokuti kuti nesimba Kuyerera zvakakwana diki uye goho impedance kunosvika gigaomov, nokupfuuridzirwa chiratidzo kunotangira pamaikorofoni, akaita zvakaoma. Somugumisiro, kuti panguo yakaderera impedance of gudzazwi rurefu impedance maikorofoni, zvakakodzera kushandisa enzanirana mudariro, iyo yakaronga munda (unipolar) transistor izvo yakarongwa maikorofoni Kamudzira redzimba.

Dzimba dzose Kamudzira dzinofanira resimbi aigona achivhara maikorofoni uye zvinowirirana pachikuva, achidzivirira kubva kwokunze yemagetsi minda.

Kazhinji, asi Kamudzira pano ari mudziyo uyo pekugara hakusi chete maikorofoni electret pacharo, asiwo enzanirana rwakazara.

Kuti tinzwisise kuti zvakakodzera kuti electret maikorofoni kana kuti maikorofoni gudzazwi, Zvaringana kubatanidza kuti mazano Jack yacho multimer. Kana mugumisiro mudziyo zvinoratidza 2-3 volts, ikoku kunoreva kuti gudzazwi zvakakodzera Kushandiswa electret maikorofoni. Vazhinji maikorofoni amplifiers kushandiswa mune dzimwe kombiyuta inzwi kadhi kana pakuvara, izvo akaverenga senguva kushanda electret maikorofoni.

Nheyo nokushanda electret mamaikorofoni inobva mano zvimwe zvinhu pamwe yakakwirira dielectric dzose, kushandura ravo pamusoro mutariri somugumisiro matambudziko inzwi wave. Electret mamaikorofoni vane yakakwirira zvikuru nemishonga, saka kuti zvinokwanisika kubatanidza navo chinhu gudzazwi dzakakwirira chiyamuro impedance.

By design, mamaikorofoni izvi vanokamurwa muzvikamu zvitatu: electret zvinhu zviri mberi panzvimbo; Electret zvinhu rinoshandisirwa tefa Kamudzira; electret ari kuseri ndiro.

Pari, mutungamiri pagadzirwe nenyanzvi kurekodha michina ndiyo kambani "pasi pasi", uyo mamaikorofoni vane vakabuditsa mukurumbira.

"Pasi pasi" at - Series, izvo zvinosanganisira zvakawanda yemashoko nounyanzvi electret mamaikorofoni, yakaitirwa kuti akasiyana ezvinhu kuti kushandiswa. Cherechedzai inofanira kubhadharwa kune nekambani utsva - maikorofoni, "pasi pasi" at - 222, iyo yakagadzirirwa kurekodha Misangano.
