Electret mafonifonifoni

Mafonifoni a electret ndi mtundu wa ma microphone. Kawirikawiri, ma microphone amenewa amagwiritsidwa ntchito ku studio zamaluso, koma akhoza kukhala angwiro kuti azisamalira. Monga lamulo, makina oyipa a microphone amagwiritsidwa ntchito popangira ma studio ojambula kunyumba.

Pa msika wamakono wa Russia mungapeze zipangizo zambirizi. Zomwe mwazikonzekera, mungathe kusankha maikolofoni osakaniza komanso ochokera kunja. Ngati tikulankhula za mavuto, ndiye kuti ma microphone ochokera kunja akuposa mtengo wa Russian. Nthaŵi zambiri, kupitirira kwakukulu kwa mitengoyi sikunayeneretsedwe, popeza maikolofoni a electro a Russian sali otsika mu khalidwe kwa akunja.

Pakalipano, ma maikolofoni a mtundu umenewu atsala pang'ono kuwonjezera ma microphone ndi mawonekedwe osiyana. Chifukwa chake ndi kuti mtengo wotsika kwambiri maikolofoni a electret amadziwika ndi kudalirika kwakukulu, kulemera kwapang'ono ndi kosalala AFC.

Mafoni amtundu uwu ndi opensitive, ena mwa iwo amapangidwa ndi filimu yopapuka kwambiri yotambasulidwa pa mphete. Mafilimu a polyethylene amatsitsimutsidwa ndi mtanda wa electron womwe umaloŵera ku kuya kwakung'ono ndipo chifukwa chake umapanga malipiro a danga omwe angathe kusungidwa kwa nthawi yokwanira.

Mtundu uwu wa dielectric uli ndi dzina lakuti "electret" - kotero maikolofoni imatchedwanso electret.

Pambuyo pake, filimuyi imakhala yosanjikiza, yomwe imagwiritsidwa ntchito ngati imodzi mwa magetsi. Chomera china ndi chitsulo chosanjikizira chomwe chipulumukiro chili pafupi ndi filimuyi.

Zowonongeka, zomwe zimayambitsidwa ndi mafunde amphamvu, zimatha kupanga magetsi pakati pa magetsi. Chifukwa chakuti mphamvu ya pompano ndi yaying'ono, ndipo zotsatira zake zimatha kufika ku gigaohms, kutumiza kwa chizindikiro chomwe chimapangidwa ndi maikolofoni ndi kovuta kwambiri. Chotsatira chake, kuti mufanane ndi mpweya wotsika wa amplifier ndi kukwera kwa maikolofoni, m'pofunika kugwiritsa ntchito sitepe yofananako, yomwe imapangidwira pamtunda (transposor), yomwe imakhala mkati mwa nyumba za makapule.

Nkhani ya capsuleyo iyenera kupangidwa ndi chitsulo, yokhoza kufufuza maikolofoni ndikugwirizanitsa chiwombankhanga, kuteteza izo kuchokera kumadera akumagetsi akunja.

Monga lamulo, kapule ndi chida chimene thupi silili kokha maikolofoni a electret, koma komanso kuwonetsera kofanana.

Kuti mumvetse ngati maikolofoni yamakono ali woyenera kulumikiza maikolofoni a electret , ndi okwanira kulumikizana ndi jack yophatikiza ya multimeter. Ngati, chifukwa chake, chidacho chikuwonetsa 2-3 volts, zikutanthauza kuti amplifier ndi yoyenera kugwira ntchito limodzi ndi maikolofoni a electret. Ma amplifiers ambiri amagwiritsidwa ntchito m'makhadi osiyana a makompyuta kapena mkati mwake, omwe apangidwira kugwira ntchito ndi microphone.

Mfundo yogwiritsira ntchito electret mafonifoni imachokera ku zothekera kwa zipangizo zina zomwe zimakhala ndi zovomerezeka kwambiri, zomwe zimasinthidwa chifukwa cha mkokomo. Electret mafonifoni amatsutsa kwambiri, kotero kuti akhoza kugwirizanitsidwa ndi amplifiers okhala ndi mpweya wabwino kwambiri.

Malingana ndi mapangidwe awo, ma microphone awa amagawidwa m'magulu atatu: chinthu cha electret chili patsogolo; Electret zakuthupi zimagwiritsidwa ntchito ku membrane yokhazikika; Electret ili pamtunda.

Mpaka pano, mtsogoleri mu kupanga zipangizo zamakono zojambula nyimbo ndi kampani "Octave", omwe ma microphone awo ali ndi mbiri yabwino.

"Octave" MCE - mndandanda womwe umaphatikizapo mitundu yambiri ya akatswiri a microret microphone, omwe apangidwa kuti azigwiritsa ntchito mosiyana. Kusamala kwakukulu kuyenera kulipidwa kwachilendo cha kampani - Maikrofoni ya Octave "MKE-222", yomwe idakonzedweratu kuti iwonetsere misonkhano.
