Lub Hloov Kho Audio

Lub Hloov Kho Audio

Audio Transformers yog tsim los siv hauv cov suab thov suab txuas rau kev sib txuas thiab impedance txuam ntawm amplifiers thiab hais lus

Raws li nce ntawm kev nce (nce) lossis nqis tawm (txo qis) lub teeb liab hluav taws xob, hloov hluav taws xob kuj tseem muaj lwm qhov chaw muaj txiaj ntsig, 0010010 nbsp; cais tawm. Txij li thaum tsis muaj hluav taws xob ncaj qha los ntawm lawv cov thawj thiab theem pib windings, hloov hluav taws xob tau muab hluav taws xob ua tiav ntawm lawv cov kev nkag mus thiab kev tsim hluav taws xob thiab cov cuab yeej raug rho tawm no kuj tseem siv tau ntawm amplifiers thiab hais lus.

Peb tau pom hauv seem no hais txog kev hloov pauv, tias lub hloov hluav taws xob yog khoom siv hluav taws xob uas tso cai rau qhov teeb meem sinusoidal input teeb liab (xws li lub suab tso hluav taws xob lossis hluav taws xob) los tsim cov paib hluav taws xob lossis hluav taws xob tsis muaj qhov cuam tshuam rau sab thiab tawm sab tom lub cev txuas rau txhua tus. lwm yam. Qhov txuas txuas no yog ua tiav los ntawm muaj ob (lossis ntau dua) cov hlua hlau (hu ua windings) ntawm cov kab hluav taws xob tooj liab nyob ib ncig ntawm cov hlau ua hlau sib nqus.

Thaum lub teeb liab AC yog siv rau qhov pib nkag winding, ib qho hluav taws xob AC teeb liab tshwm ntawm cov zis theem ob qhov sib hloov vim yog qhov sib luag txuas ntawm cov hlau mos mos. Cov kev sib hloov sib piv ntawm cov tswv yim thiab cov zis hlau coils muab txoj hauv kev nce siab lossis txo qis ntawm cov teeb liab thov li nws dhau ntawm qhov hloov pauv.

Tom qab ntawd audio transformers tuaj yeem raug txiav txim siab los ntawm theem lossis nce qib, tab sis ntau dua li qhov raug mob los tsim cov hluav taws xob tshwj xeeb, cov hloov suab audio yog tsim tshwj xeeb rau kev sib txuam impedance. Tsis tas li, hloov hluav taws xob nrog qhov hloov pauv ntawm 1: 1, tsis hloov qhov voltage lossis qib tam sim no tab sis hloov cais lub xov hluav taws xob thawj ntawm ob sab. Hom transformer no paub feem ntau ua Isolation Transformer.

Transformers tsis yog cov cuab yeej ntse, tab sis tuaj yeem siv ua cuab yeej bidirectional kom cov thawj cov xov xwm sib npaug winding tuaj yeem dhau los ua cov khoom siv winding thiab cov tso zis theem pib lub cev muaj peev xwm dhau los ua kev tawm tswv yim thiab vim los ntawm cov xwm txheej no, qhov hloov pauv tuaj yeem muab lub teeb liab thaum siv nyob rau hauv ib qho kev taw qhia los yog lub teeb liab poob thaum siv rov qab los pab sib piv cov teeb liab lossis hluav taws xob sib txawv ntawm cov khoom siv sib txawv.

Nco ntsoov tias ib lub hloov hluav taws xob tuaj yeem muaj ntau thawj lossis theem pib thiab cov kab hlau no tseem yuav muaj ntau txoj kev sib txuas hluav taws xob lossis "kais" raws lawv qhov ntev. Qhov kom zoo dua ntawm ntau lub kais suab hloov pauv yog tias lawv muaj cov hluav taws xob sib txawv raws li qhov sib txawv ntawm cov nyiaj poob lossis cov sib tw sib txawv uas ua rau lawv muaj txiaj ntsig rau kev sib txuam ntawm cov amplifiers thiab cov lus hais tawm.

Raws li lawv lub npe qhia, 0010010 nbsp; suab hloov pauv 0010010 nbsp; yog tsim los ua haujlwm nyob rau hauv cov kab ke ua suab thiab ntau yam xws li tuaj yeem muaj cov ntawv thov nkag rau theem nkag (microphones), theem tsim tawm (lub suab nrov) , inter-theem txuas ntxiv nrog rau impedance txuam ntawm amplifiers. Hauv txhua qhov xwm txheej, qhov nquag teb, kev cuam tshuam thawj thiab theem nrab ntawm kev cuam tshuam thiab lub zog muaj peev xwm txhua yam yuav tsum xav txog.

Audio thiab impedance txuam transformers zoo sib xws nyob rau hauv kev tsim kom tsawg zaus voltage thiab hloov hluav taws xob, tab sis lawv ua haujlwm dhau ntau qhov ntau ntawm ntau zaus zaus zaus. Piv txwv li, 20 Hz rau 20 kHz suab lus ntau. Cov hloov hluav taws xob kuj tseem tuaj yeem ua DC hauv ib lossis ntau ntawm lawv cov cua kab rau kev siv hauv digital audio applications raws li hloov hluav taws xob voltage thiab cov theem tam sim no ntawm high zaus.
