Lub tweeter ntawm ob txoj kev hais lus dais lub luag haujlwm tseem ceeb ntawm tag nrho cov kab hluav taws xob siab. Nws tweeter ib feem ntawm tus neeg hais lus kom dais tag nrho lub zog ntawm qhov siab zaus, txhawm rau ua kom lub tweeter no tsis dhau, yog li koj tsis tuaj yeem xaiv lub tweeter nrog qhov qis crossover point, yog tias koj xaiv qhov qis crossover point yuav ua rau lub tweeter ntawm lub tweeter yuav dhau los ntawm lub zog loj heev, uas yuav ua rau lub tweeter hlawv, nyob rau hauv ib txwm muaj xwm txheej 0, tus crossover point yuav tsis ntau dua li tweeter. hertz ua!

Lub tweeter tseem yuav tsum tau siv ua ke nrog lub woofer. Nyob rau tib lub sijhawm, peb kuj yuav tsum xav txog qhov tweeter qhov txwv tsawg zaus, txwv tsis pub, yuav muaj qhov tsis zoo ntawm ob zaus. 6.5-nti hais lus lub siab-zaus txwv feem ntau tsis siab tshaj 5,000 Hz, thaum peb tsim lub crossover point, yog hais tias peb tawm ib tug ob npaug ntawm cov zaus, ces qhov crossover point ntawm qhov tsim nyog coj tus nqi ntawm txog 2.5000 Hz, zoo ib yam, qhov tsawg-zaus txwv ntawm lub tweeter, yog hais tias ib tug kuj yuav tsum tau ua raws li ub frequency xam. qis dua 1.2500 Hz. Muab ob npaug rau qhov zaus los xam, nws yuav tsum qis dua 1.2500 Hz.

Rau qhov yuav tsum tau ntawm lub tweeter, ua ntej ntawm tag nrho cov, lub resonant zaus F0 yuav tsum tsis txhob siab tshaj ib nrab ntawm cov zaus ntawm crossover point, txwv tsis pub, nws yuav ua rau crossover point nyob rau hauv txoj hauj lwm ntawm zaus teb yuav yog ib qho teeb meem, ib tug tsim nyog ntau yam yuav tsum tau resonant zaus ntawm tus hais lus tsis siab tshaj 1.2500 Hz. Yog tias qhov kev txhawb nqa woofer loj dua 6.5 ntiv tes, ntawm lub sijhawm no, tweeter qhov txwv tsawg zaus yuav siab dua me ntsis, vim hais tias ntawm lub sijhawm no lub woofer lub peev xwm loj yuav raug kho kom zoo, qhov crossover point yuav raug nqa, qhov no yog raws li tus yam ntxwv ntawm woofer txiav txim siab!

Thaum xaiv lub tweeter, peb kuj yuav tsum tau them sai sai rau yog lub rhiab heev, nyob rau hauv lub hauv paus ntsiab lus lub tweeter rhiab heev yuav tsis tau qis dua lub woofer rhiab heev. Yog tias nws qis dua, nws yuav nyuaj rau txo qhov rhiab heev ntawm tus neeg hais lus los ntawm qee tus neeg hais lus attenuation, yog tias lub tshuab hluav taws xob crossover, qhov no tsis yog qhov tseem ceeb, thaum lub tweeter rhiab heev tshaj qhov rhiab heev ntawm tus neeg hais lus ntses bass thaj tsam, peb tuaj yeem dhau los ntawm tweeter ntawm cov kab ntawm qee cov resistors uas muaj qee qhov inhibitory chaw kom txo tau ob treble thiab zoo meej.

Qhov kawg uas yuav tsum tau taw qhia yog tias tus yam ntxwv ntawm tweeter nws tus kheej muaj kev cuam tshuam loj heev rau tag nrho cov kab ke, yog li peb yuav tsum mus thiab xaiv lub tweeter nrog qis qis thiab kev ua haujlwm zoo!
