Hauv cov lus yooj yim, nws yog hais txog lub tshuab ua kom muaj zog hauv lub txee hais lus tseem ceeb lossis lub txee subwoofer. Tom qab lub teeb liab suab raug nthuav dav thiab ua tiav, lub tshuab hais lus nws tus kheej ua si rov qab kom nws suab. Ua kom loj dua.

Lub tshuab hais lus yog qhov kawg ntawm tag nrho lub suab. Nws lub luag haujlwm yog hloov lub zog suab mus rau hauv lub zog suab sib xws thiab xa mus rau qhov chaw. Nws yog ib feem tseem ceeb heev ntawm lub suab thiab yog lub luag haujlwm hloov cov teeb liab hluav taws xob mus rau hauv cov teeb liab acoustic rau tib neeg. Txoj haujlwm ntawm kev mloog ncaj qha rau pob ntseg.

Cov qauv ntawm tus neeg hais lus:

Cov neeg hais lus hauv khw muaj ntau yam duab thiab xim, tab sis txawm yog hom twg los xij, lawv muaj ob ntu tseem ceeb:tus neeg hais luschav tsev (hu ua Yangsheng chav tsev) thiab lub txee. Ntxiv rau, feem ntau cov neeg hais lus siv tsawg kawg yog ob lossis ob tsuas yog cov chav hais lus saum toj no siv qhov hu ua ntau-channel suab rov ua dua, yog li qhov crossover kuj yog ib feem tseem ceeb.

Kev faib tawm ntawm cov neeg hais lus:

Kev faib tawm ntawm cov neeg hais lus muaj ntau lub kaum sab xis thiab cov qauv sib txawv. Raws li cov qauv acoustic ntawm cov neeg hais lus, muaj cov thawv airtight, cov thawv inverted (tseem hu ua cov thawv reflection qis zaus), cov neeg hais lus radiator passive, thiab cov neeg hais lus kab kis. Lub thawv inverter yog lub ntsiab lus tseem ceeb ntawm kev ua lag luam tam sim no; los ntawm qhov pom ntawm qhov loj me thiab qhov chaw ntawm cov neeg hais lus, muaj cov thawv hauv pem teb thiab cov thawv txee ntawv. Tus qub yog qhov loj me thiab feem ntau muab tso ncaj qha rau hauv av. Qee zaum, cov taw uas nqus tau kev co kuj tau teeb tsa hauv qab cov neeg hais lus. . Vim yog qhov loj ntawm lub txee thiab qhov yooj yim ntawm kev siv cov woofers loj dua thiab ntau dua, lub thawv hauv pem teb mus rau qab nthab feem ntau muaj qhov zaus qis zoo dua, qib suab siab dua thiab muaj peev xwm nqa tau lub zog loj, yog li nws tsim nyog rau thaj chaw mloog loj dua lossis cov kev xav tau ntau dua Lub thawv txee ntawv me me thiab feem ntau muab tso rau ntawm lub tripod. Nws yog tus cwj pwm los ntawm kev tso chaw yooj yim thiab tsis siv qhov chaw. Txawm li cas los xij, vim yog qhov ntim ntawm lub thawv thiab qhov txwv ntawm txoj kab uas hla thiab tus lej ntawm woofers, nws qhov zaus qis feem ntau qis dua li ntawm lub thawv hauv pem teb, thiab nws lub zog nqa Thiab qhov tso zis suab siab kuj me dua, uas yog qhov tsim nyog rau kev siv hauv qhov chaw mloog me dua; raws li qhov bandwidth nqaim ntawm kev ua si, muaj cov neeg hais lus broadband thiab cov neeg hais lus narrowband. Feem ntau cov neeg hais lus tau tsim los npog Lub zaus band dav li sai tau yog lub tshuab hais lus dav dav. Hom tshuab hais lus narrow-band feem ntau yog lub subwoofer (subwoofer) uas tau tshwm sim nrog lub tsev ua yeeb yam hauv tsev, uas tsuas yog siv los rov qab kho qhov zaus ultra-low rau qhov zaus nqaim heev; raws li seb puas muaj lub zog amplifier ua-hauv, nws tuaj yeem faib ua cov neeg hais lus passive thiab cov neeg hais lus nquag, tus qub tsis muaj lub amplifier ua-hauv thiab tom kawg muaj. Tam sim no, feem ntau cov neeg hais lus hauv tsev yog passive, tab sis subwoofers feem ntau yog nquag.
