Electret umbhobho

umbhobho Electret uhlobo epholisayo imibhobho ngokufanele. Ezimweni eziningi, lezi kusetshenziswa imibhobho studios professional, kodwa ukuze kube kuhle efanelekayo ngezinhloso amateur. Ngokuvamile, imibhobho capacitor electret wayevame ukusebenzisa ukuhlomisa studio ekhaya ukurekhoda.

Ezimakethe yesimanje Russian ungathola eziningi ezihlukahlukene imishini. Phakathi iziphakamiso zamanje Ungakhetha imakhrofoni electret, kokubili ukukhiqiza angaphandle kanye ezifuywayo. Uma sikhuluma ngezindaba izindleko, imibhobho zokukhiqiza angaphandle ayabiza kunamawashi Russian. Ezimweni eziningi, lokhu kwanda kwamanani akuyona okuningi walungisiswa njengoba electret umbhobho ukukhiqizwa Russian akuyona eliphansi in izinga kwabangcwele angaphandle.

Okwamanje imibhobho cishe lwaludlula lolu hlobo imibhobho kokuba design ehlukene. Isizathu siwukuthi at aphansi kakhulu izindleko electret umbhobho libhekene enokwethenjelwa, isisindo ongaphakeme kanye flat imvamisa impendulo.

Imibhobho zaloluhlobo zinzima capacitors, ezinye zazo zingqimba eyenziwe ifilimu mncane kakhulu welulela phezu indandatho. ifilimu Plastic is zishiswe ngemisebe kwavela khona inhlansi electron ukuthi ukungena ukujula encane, futhi ngenxa yalokho ukudala icala isikhala kokuba ikhono ugcine isikhathi eside.

Kulesi hlobo insulators banegama "electret" - ukuze imakhrofoni ubizwa nangokuthi i electret.

Ngemva kwalokho esikhulu ifilimu ngokwanele mncane ungqimba metal, elisetshenziswa njengesibonakaliso omunye electrode. Njengoba omunye electrode kuphuma isilinda metal, ebusweni kabani Planar iseduze ifilimu.

oscillations sayo okuyinto zibangelwa amagagasi acoustic, uyakwazi ukudala i kagesi phakathi electrode. Ngenxa yokuthi amandla lamanje lincane ngokwanele futhi impedance elanga afinyelela gigaomov, isiginali ukudluliswa eyenziwe microphone, wenza nzima impela. Ngenxa yalokho, ukuze ukufanisa impedance eliphansi amplifier nge okusezingeni eliphezulu impedance umbhobho, kubalulekile ukusebenzisa isigaba ofanayo, okuyinto ahlelwe enkundleni (unipolar) Transistor zazo wahlela imakhrofoni capsule izindlu.

Leli bhokisi we capsule kufanele wenziwe metal uyakwazi ukuhlolwa umbhobho nokuvumelanisa esiteji, ukuvikela ke kusukela yangaphandle Amasimu kagesi.

Ngokuvamile, capsule lapha yidivayisi likabani izindlu akuyona kuphela umbhobho electret ngokwayo, kodwa futhi esigabeni ezifanayo.

Ukuze uzwisise ukuthi kufanelekile i-microphone electret noma ukuthi i-amplifier umbhobho, kwanele ukuxhuma jack uvo we multimer. Uma umphumela idivayisi ibonisa 2-3 volts, lokhu kusho ukuthi lo mshini wokukhulisa umsindo kufanelekile ukusetshenziswa nge-microphone electret. Abaningi umbhobho yokukhulisa umsindo elisetshenziswa kwezinye ikhadi ikhompyutha umsindo noma esakhelwe, okuyinto kubalwa njengoba isikhathi ukusebenza nge-microphone electret.

Umgomo we operation ye electret imibhobho kusekelwe ikhono ezinye izinto nge high njalo Kwe-dielectric Heating, ukushintsha ubuso babo icala ngenxa umthelela umsindo wegagasi. imibhobho Electret babe ukumelana eliphezulu kakhulu, ukuze kungenzeka ukuxhuma kubo ku-amplifier nge high impedance input.

Ngu design, lemibhobho zihlukaniswe ngezigaba ezintathu: impahla electret uku phambi isikhundla; impahla Electret lisetshenzisiwe ulwelwesi nezimo; electret ivuliwe plate emuva.

Kuze kube manje, umholi ukukhiqizwa professional imishini yokuqopha inkampani "Octave", ogama imibhobho unayo i idumela lihle.

"Octave" FEM - Series, ehlanganisa onobuhle eziningana professional electret imibhobho, okuyinto zenzelwe izimo ezahlukene ukusetshenziswa. Ngokukhethekile kufanele kukhokhelwe eseyintsha yenkampani - umbhobho, "Octave" FEM - 222, okuyinto yakhelwe zokuqopha izingqungquthela.
