XDEC cov tuam txhab coj koj kom paub qhov tseem ceeb ntawm tus neeg hais lus
Cov neeg feem coob paub tias tus neeg hais lus tau ntsuas impedance, lub zog, zaus tus yam ntxwv, rhiab heev, distortion ntawm cov tsis, tab sis tus neeg hais lus nyob deb tshaj li pem hauv ntej ntawm cov tsis, muaj ntau, tab sis peb feem ntau tsis muaj kev nkag siab zoo txog cov nram qab no XDEC hais lus manufacturers yuav muab rau koj ib txoj kev!
1.o zog
Lub zog ntawm tus neeg hais lus tau muab faib ua lub zog ntsuas, lub zog tsawg kawg, lub zog siab tshaj plaws thiab lub zog tam sim, tag nrho hauv W.
Rated hwj chim, tseem hu ua nominal hwj chim, hais txog tus hais lus rau ib tug ntev lub sij hawm ib txwm ua hauj lwm tas mus li tsis pom tseeb distortion ntawm input nruab nrab hwj chim.
Lub zog tsawg kawg nkaus, tseem hu ua lub zog pib, yog hais txog qhov ntsuas hluav taws xob hluav taws xob tus nqi uas tus neeg hais lus tuaj yeem raug thawb mus ua haujlwm.
Lub zog siab tshaj plaws kuj hu ua qhov siab tshaj plaws nqa lub zog, nws yog lub zog siab tshaj plaws uas tuaj yeem nqa tau thaum tus hais lus ua haujlwm tsis tu ncua ntev.
Instantaneous hwj chim tseem hu ua instantaneous bearing hwj chim, nws yog taw tes rau tus hais lus nyob rau hauv ib tug luv luv lub sij hawm (10ms) muaj peev xwm dais lub siab tshaj plaws hwj chim, feem ntau 8 ~ 30 lub sij hawm ntawm rated hwj chim.
2. Qhov ntsuas impedance
Qhov ntsuas impedance ntawm tus neeg hais lus kuj tseem hu ua tus nqi impedance nominal, uas yog qhov tsawg kawg nkaus impedance ntawm tus neeg hais lus tom qab lub siab tshaj plaws, suav nrog 4Ω, 6 Ω, 8 Ω, 16Ω thiab 32 Ω.
Qhov ntsuas impedance feem ntau yog kwv yees li 1.1 npaug ntawm dc tsis kam ntawm lub suab coil.
3. Lub resonant zaus
Resonant zaus yog hais txog qhov qis tshaj plaws uas tussuab nrovtuaj yeem rov ua dua, uas cuam tshuam nrog qhov loj ntawm lub suab nrov caliber.
Lub resonance zaus ntawm lub woofer feem ntau txo qis nrog qhov nce ntawm nws cov caliber. Lub resonance zaus ntawm 6in (hauv=0.0254m) woofer yog hais txog 50HZ, uas ntawm 8in woofer yog hais txog 40HZ, ntawm 10in woofer yog hais txog 30HZ, thiab ntawm 12in woofer yog hais txog 20HZ.
Resonant zaus yog ib qho tseem ceeb parameter uas txiav txim siab qhov tsawg zaus tus yam ntxwv ntawm lub suab nrov. Qhov qis dua tus nqi yog, qhov zoo dua qhov zoo thiab kev siv ntawm cov ntses bass thaj tsam replayed los ntawmsuab nrov(tus neeg hais lus).
4. Cov yam ntxwv zaus
Tus yam ntxwv zaus ntawm tus neeg hais lus yog hais txog txoj cai hais tias cov zis suab siab ntawm qhov siv ncej ntawmtus hais lushloov nrog qhov zaus ntawm lub teeb liab input thaum lub teeb liab voltage ntawm tus input speaker yog tas li. Nws yog ib tug zaus teb nkhaus uas hloov nrog zaus (frequency teb rau luv), uas qhia txog lub peev xwm ntawm tus neeg hais lus rau radiate suab nthwv dej ntawm txawv frequencies.
Qhov zaus teb nkhaus ntawm tus neeg hais lus yog tsis tu ncua nkhaus nrog ntau lub ncov thiab hav. Lub resonant zaus ntawm tus neeg hais lus yog suav tias yog qhov tsawg zaus unlimited zaus, thiab qhov kev sib tshuam ntawm qhov siab zaus kawg ntawm qhov zaus teb nkhaus yog suav tias yog cov zaus sab saud. Qhov ntau zaus ntawm qhov kev txwv qis ntawm qhov tsawg zaus thiab qhov txwv siab tshaj plaws yog hu ua qhov muaj txiaj ntsig zoo ntawm cov neeg hais lus los ntawm XDEC cov tuam txhab.
Lub flatter tus hais lus zaus teb nkhaus yog, qhov me me qhov zaus distortion yog, thiab qhov dav qhov ntau zaus yog.
Qhov ntau zaus ntawm qhov dav dav woofer yog nyob nruab nrab ntawm 20HZ ~ 3kHZ, qhov ntau zaus ntawm nruab nrab -ntau tus hais lus yog nyob nruab nrab ntawm 500HZ ~ 5kHZ, thiab qhov ntau zaus ntawm tweeter yog nyob nruab nrab ntawm 2 ~ 20kHZ.
