Tsab xov xwm no yuav qhia rau koj paub tias passive radiator yog dab tsi

Passive radiator yog ib lub tshuab suab uas siv "passive radiator" feem ntau muaj ib lub active speaker unit thiab ib lub passive unit (passive radiator). Lub passive unit feem ntau zoo ib yam li lub active speaker unit, tab sis nws tsis muaj lub voice coil lossis drive magnet.

Cov neeg siv tsis paub feem ntau suav tias cov passive radiators yog cov khoom ntawm cov chaw tsim khoom suab uas txiav cov ces kaum. Nws zoo ib yam li lub bass unit ib txwm; Tab sis sab hauv, cov qauv txawv heev. Tsis muaj cov xov hlau txuas rau nws, thiab tsis muaj cov hlau nplaum tsav tsheb ib txwm nyob tom qab. Qee cov chaw tsim khoom thiab cov neeg muag khoom txawm piav qhia nws tias yog "lub bass loj ntawm lub tso suab" lossis "ob chav bass." Tab sis qhov tseeb, nws tsis tsim cov bass muaj zog dua.

Yog li ntawd, vim li cas peb thiaj siv cov passive radiators? Nws yog dab tsi? Cov txiaj ntsig ntawm kev muaj nws rau ntawm lub tso suab yog dab tsi?

Peb yuav piv lub passive radiator rau "qhov hnyav" ntxiv rau "lub caij nplooj ntoos hlav." Lub caij nplooj ntoos hlav "muaj cov diaphragm rings ntawm ntug ntawm lub tais ntawv thiab cua kaw hauv lub thawv." "Qhov hnyav" yog ua los ntawm lub tais ntawv thiab lub counterweight. Lub counterweight yog ib feem tseem ceeb hauv kev tsim ntawm passive radiator, uas yog ncaj qha cuam tshuam nrog lub suab kawg.

Lub tshuab cua txias passive radiator tuaj yeem tsim cov resonance los ntawm kev hloov qhov hnyav sib npaug, zoo li lub tuning fork. Txawm li cas los xij, tsis zoo li lub tuning forks, qhov kev co ntawm cov tshuab cua txias passive radiators tsis lwj sai sai hauv qee qhov ntau ntawm qhov zaus resonant. Cov tshuab cua txias passive feem ntau lwj ntawm tus nqi ntawm 18db ib octave. Txawm hais tias qhov nkhaus zoo li ntxhab, nws tseem muab lub suab ib nrab yim rau tus neeg hais lus. Qhov no tso cai rau nws kom tsim los resonate ntawm qhov tob tshaj qhov ncav cuag ntawm tus neeg hais lus lub woofer, yam tsis muaj "kev sib txuas" tseem ceeb ntawm lub suab zaus ntawm woofer thiab ntawm lub passive radiator, ua rau muaj qhov nkhaus suab du los ntawm siab mus rau qis.

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

Ib qho ntawm cov txiaj ntsig zoo ntawm cov tshuab suab uas muaj cov passive radiators yog tias lawv tuaj yeem hloov lub nra hnyav ntawm kev tsim cov bass los ntawm qhov me me ntawm lub woofer mus rau qhov loj dua ntawm lub passive radiator (lub woofer xav tau qhov siab tshaj plaws ntawm kev thawb cua ntawm qhov taw tes "-3dB" kom tsim tau tib lub suab nrov hauv qhov ntau zaus). Ntawm qhov no, lub passive radiator tuaj yeem nqa tawm ntau dua linear vibration (kev txav mus los ntawm lub tais ntawv sab hauv thiab sab nraud). Lwm qhov txiaj ntsig pom tseeb yog tias qhov teb zaus qis txuas ntxiv qis dua. Tsis tas li ntawd, qhov me me ntawm lub bass unit tuaj yeem siv rau hauv kev tsim, yog li cov bass thiab nruab nrab zaus teb tuaj yeem raug dua, sib cais zoo dua.
