Electret microphone

microphone Electret i uhlobo imibhobho ekondensa. Kwiimeko ezininzi, ezi imibhobho zisetyenziswa kumagumbi zobungcali, kodwa kusenokuba kuhle ukuba isetyenziselwe iinjongo engahlawulwayo. Ngokuqhelekileyo, imibhobho capacitor electret wayedla ukuxhobisa ukurekhoda ekhaya studio.

Kwimarike Russian mihla Ungafumana uluhlu enkulu yezixhobo. Phakathi izindululo zangoku ungakhetha umbhobho electret, zombini imveliso kumazwe angaphandle kunye zasekhaya. Ukuba uthetha ngemiba ebiziwe, imibhobho yemveliso amazwe ibiza ngaphezu Russian. Kwiimeko ezininzi, oku kunyuka kwamaxabiso akufuneki kakhulu sigwetyelwe nje electret microphone imveliso Russian ayikho enasilela esemgangathweni kwabo amazwe.

Okwangoku imibhobho cishe indawo olu hlobo imibhobho ukuba uyilo ezahlukeneyo. Isizathu kukuba kwi eliphantsi kakhulu iindleko electret umbhobho luphawulwa ukuthembeka phezulu, ubunzima phantsi kwaye iflethi impendulo rhoqo.

Imibhobho elolu hlobo capacitors, ezinye zazo amacwecwe ezenziwe mncane kakhulu umboniso kolulwa phezu ngomsesane. Plastic Bhanya okufakwe kunye msebe electron engena ukuya kubunzulu encinane, yaye ngenxa yoko ukudala isigxina isithuba kokuba uyakwazi ukugcina ixesha elide.

Kule hlobo insulators unegama "electret" - ukuze umbhobho kubizwa ngokuba i electret.

Kamva xa kuthelekiswa ifilimu ngokwaneleyo ibhityile umaleko metal, esetyenziswa enye i electrode. Njengokuba elinye electrode kuphuma cylinder metal, umphezulu kabani Planar ibekwe kufuphi film.

oscillations walo zibangelwa ngamaza yiacoustic, ezinako ukudala umsinga wombane phakathi electrode. Ngenxa yokuba amandla current incinane ngokwaneleyo kwaye ukuvimba imveliso ifikelela gigaomov, uphawu ukudluliselwa eyenziwe microphone, wenza nzima kakhulu. Ngenxa yoko, ukuze utshatise ukuvimba eliphantsi lo mshini kunye ukuvimba umbhobho omkhulu, kuyimfuneko ukusebenzisa kwinqanaba ofanayo, leyo amalungiselelo kwi endle (unipolar) transistor leyo zicwangciswe izindlu microphone philisi.

Izindlu le philisi kufuneka zenziwe kwensimbi ekwaziyo sokuhluza microphone nokuhambelanisa eqongeni, ukukhusela kuyo kwiinkalo yangaphandle zombane.

Ngokuqhelekileyo, le philisi apha sisixhobo ekubhaliswe izindlu nje kuphela microphone electret ngokwayo; kodwa ke efana yeqonga.

Ukuze siqonde ukuba ilungele ukuba umbhobho electret okanye msindo umbhobho, kwanele ukudibanisa kwigalelo jack ye multimer. Ukuba iziphumo ifowuni iyaluveza 2-3 volts, oku kuthetha ukuba lo mshini ilungele ukusetyenziswa kunye microphone electret. Uninzi yokukhulisa umbhobho ezisetyenziswa kwezinye ikhadi lesandi ikhompyutha okanye eyakhelwe-ngaphakathi, ezithi ibalwe njengexesha ukusebenza microphone electret.

Umgaqo esebenza ngayo imibhobho electret isekelwe phezu isakhono kwezinye izinto uhlale high Heating, ukutshintsha isigxina sazo phezu ngenxa iimpembelelo isandi otshangatshangiswayo. imibhobho Electret babe nokumelana eliphezulu kakhulu, kangangokuba kunokwenzeka ukudibanisa ukuba ngombhobho kunye igalelo amanzi eliphezulu.

Xa design, lemibhobho zahlulwe ngokweendidi ezintathu: impahla electret ukwimo phambi; izinto Electret lusetyenziswa ndizayo nezimo; electret phezu kwipleyiti umva.

Ukuza kuthi ga ngoku, kwinkokeli ukuvelisa izixhobo yokurekhoda zobungcali nkampani "ilizwi", ogama imibhobho kufuneka abalasela.

"Ilizwi" FEM - Series, ebandakanya imifuziselo eziliqela imibhobho electret professional, leyo eyenzelwe ukuba iimeko ezahlukeneyo lokusetyenziswa. ingqalelo ekhethekileyo kufuneka ihlawulwe yenkampani ezintsha - microphone, "ilizwi" FEM - 222, nto leyo yenzelwe recording neenkomfa.
