Kab lus no yuav qhia rau koj paub tias dab tsi yog passive radiator

Passive radiator yog lub suab kaw lus uas siv "passive radiator" feem ntau muaj ib chav hais lus nquag thiab ib chav passive (passive radiator).Ib chav tsev passive feem ntau zoo ib yam li lub suab hais lus, tab sis tsis muaj lub suab coil lossis tsav hlau nplaum.

Passive radiators feem ntau suav hais tias yog cov neeg siv tsis paub tseeb raws li cov khoom lag luam suab uas txiav cov fab.Nws zoo ib yam li cov ntses bass thaj tsam li niaj zaus;Tab sis sab hauv, cov qauv sib txawv heev.Tsis muaj ib qho txhuas txuas rau nws, thiab tsis muaj cov hlau nplaum uas niaj hnub tsav tsheb nyob tom qab.Qee cov tuam ntxhab thiab cov neeg muag khoom txawm piav qhia tias nws yog "loj ntses bass thaj tsam ntawm tus hais lus" lossis "ob npaug ntses bass thaj tsam."Tab sis nyob rau hauv kev muaj tiag, nws tsis tsim ib tug muaj zog bass thaj tsam.

Yog li vim li cas peb thiaj siv passive radiators?Nws yog dab tsi?Dab tsi yog qhov zoo ntawm kev muaj nws ntawm tus hais lus?

Peb yuav muab piv rau lub tshuab hluav taws xob passive rau "qhov hnyav" ntxiv rau "caij nplooj ntoos hlav."Lub caij nplooj ntoos hlav "muaj cov diaphragm rings ntawm ntug ntawm daim ntawv phiab thiab cov cua nyob rau hauv lub thawv.""Qhov hnyav" yog ua los ntawm cov ntaub ntawv phiab thiab counterweight.Lub counterweight yog ib qho tseem ceeb nyob rau hauv kev tsim ntawm passive radiator, uas yog ncaj qha ntsig txog lub suab kawg.

Passive radiator tuaj yeem tsim cov resonance los ntawm kev hloov lub counterweight, zoo ib yam li lub diav rawg.Txawm li cas los xij, tsis zoo li cov nkhaus tuning, qhov kev vibration ntawm passive radiators tsis lwj sai sai nyob rau hauv ib qho chaw deb ntawm lub resonant zaus.Passive radiators feem ntau lwj ntawm tus nqi ntawm 18db ib octave.Txawm hais tias qhov nkhaus zoo li ntxhab, nws tseem muab lub suab nrov ib nrab-yim rau tus neeg hais lus.Qhov no tso cai rau nws los tsim kom muaj suab nrov ntawm qhov tob tshaj qhov ncav cuag ntawm tus neeg hais lus lub woofer, yam tsis muaj qhov tseem ceeb "disconnect" ntawm lub suab zaus ntawm lub woofer thiab lub passive radiator, uas ua rau lub suab nkhaus ntawm siab mus rau qis.

Feem ntau hais lus, passive radiators vibrate zoo li levers: thaum lub woofer daim ntawv phwj txav mus rau sab nraud, nws daim ntawv phwj txav mus rau sab hauv;Los yog thaum lub woofer lub phiab ntawv txav mus rau sab hauv, nws lub phiab ntawv txav mus rau sab nraud.Tab sis qhov ntawd tsis yog li ntawd.Lub basso phiab thiab passive radiator phiab tuaj yeem txav mus rau sab hauv lossis sab nraud tib lub sijhawm (qhov no yog hu ua "hauv theem"), lossis kev sib xyaw ua ke ntawm kev tawm tsam ("tawm ntawm theem" ​​- qhov piv txwv loj tshaj plaws yog "tawm ntawm theem" 180 degrees ", raws li tau hais ua ntej nrog lub zog).Hauv kev xav, rau ob lub suab ntxiv, lawv yuav tsum txav mus rau theem nruj.Txawm li cas los xij, vim muaj kev txwv lub cev, feem ntau muaj qhov sib txawv me ntsis hauv cov tshuab resonance.

Ib qho txiaj ntsig zoo ntawm lub tshuab suab nruab nrog cov hluav taws xob tsis muaj zog yog tias lawv tuaj yeem hloov lub nra ntawm kev tsim cov ntses bass thaj tsam los ntawm qhov loj me ntawm lub woofer mus rau qhov loj ntawm lub tshuab hluav taws xob passive (lub woofer xav tau qhov siab tshaj plaws ntawm huab cua thawb ntawm qhov taw tes. "-3dB" los tsim tib lub suab nrov hauv qhov ntau zaus).Nyob rau ntawm lub sijhawm no, lub tshuab hluav taws xob tsis muaj zog tuaj yeem nqa tawm ntau qhov kev vibration (lub zog reciprocating ntawm daim ntawv phwj sab hauv thiab sab nraud).Lwm qhov kom zoo dua yog tias qhov tsawg zaus teb point txuas ntxiv qis dua.Tsis tas li ntawd, qhov me me ntawm chav tsev ntses bass thaj tsam tuaj yeem siv rau hauv kev tsim, kom cov ntses bass thaj tsam thiab nruab nrab zaus teb tuaj yeem ua tau zoo dua, kev sib cais zoo dua.
