1. Taw qhia rau cov neeg hais lus

Speaker yog hais txog ib lub cuab yeej uas tuaj yeem hloov cov cim suab rau hauv suab. Nyob rau hauv layman cov ntsiab lus, nws yog hais txog lub built-in hwj chim amplifier nyob rau hauv lub ntsiab hais lus txee los yog lub subwoofer txee. Tom qab lub suab teeb liab tau nthuav dav thiab ua tiav, tus neeg hais lus nws tus kheej rov qab lub suab kom nws suab. Tau loj dua.

Tus hais lus yog lub davhlau ya nyob twg ntawm tag nrho lub suab kaw lus. Nws txoj haujlwm yog los hloov lub zog rau hauv lub zog sib xws thiab xa mus rau qhov chaw. Nws yog ib qho tseem ceeb heev ntawm lub suab kaw lus thiab yog lub luag haujlwm rau kev hloov hluav taws xob teeb liab mus rau hauv acoustic signals rau tib neeg. Lub luag haujlwm ntawm kev mloog ncaj qha rau pob ntseg.

Lub ntsiab lus ntawm tus hais lus:

Cov neeg hais lus nyob rau hauv kev ua lag luam tuaj nyob rau hauv tag nrho cov duab thiab xim, tab sis tsis muaj teeb meem dab tsi yog, lawv yog tsim los ntawm ob qho yooj yim qhov chaw: lubtus hais lusunit (hu ua Yangsheng unit) thiab lub txee. Tsis tas li ntawd, cov neeg hais lus feem ntau siv tsawg kawg yog ob lossis ob qho Tsuas yog cov hais lus saum toj no tsuas yog siv lub npe hu ua ntau lub suab tsim tawm, yog li crossover kuj yog ib feem tseem ceeb. Tau kawg, kuj tseem tuaj yeem muaj cov paj rwb suab nrov, cov raj thim rov qab, folded "labyrinth kav", thiab cov neeg hais lus txhawb zog. Ribs / reinforced suab rwb thaiv tsev boards thiab lwm yam khoom, tab sis cov khoom no tsis indispensable rau ib tug hais lus. Cov khoom tseem ceeb tshaj plaws ntawm tus neeg hais lus tsuas yog peb ntu: chav hais lus, txee thiab crossover.

Classification ntawm cov neeg hais lus:

Kev faib tawm ntawm cov neeg hais lus muaj ntau lub kaum ntse ntse thiab cov qauv. Raws li cov qauv acoustic ntawm cov neeg hais lus, muaj cov thawv airtight, cov thawv inverted (tseem hu ua cov thawv uas tsis tshua muaj kev cuam tshuam), cov neeg hais lus radiator passive, thiab cov neeg hais lus sib kis. Lub thawv inverter yog lub ntsiab ntawm kev ua lag luam tam sim no; los ntawm qhov kev xav ntawm qhov loj thiab qhov chaw ntawm cov neeg hais lus, muaj cov thawv hauv pem teb thiab cov thawv ntawv. Tus qub yog qhov loj me me thiab feem ntau muab tso ncaj qha rau hauv av. Qee zaum, kev poob siab-absorbing taw kuj tau nruab rau hauv qab cov neeg hais lus. . Vim lub ntim loj ntawm lub txee thiab qhov yooj yim ntawm kev siv cov woofers loj thiab ntau dua, lub thawv hauv pem teb-rau-qab nthab feem ntau muaj qhov tsawg zaus zoo dua, cov zis siab dua qib siab thiab lub zog muaj peev xwm nqa tau, yog li nws tsim nyog rau thaj chaw mloog loj lossis ntau qhov kev xav tau Lub thawv ntawv lub thawv me me thiab feem ntau muab tso rau ntawm lub npov. Nws yog tus cwj pwm los ntawm qhov chaw yooj yim thiab tsis nyob hauv qhov chaw. Txawm li cas los xij, vim qhov ntim ntawm lub thawv thiab qhov txwv ntawm txoj kab uas hla thiab tus naj npawb ntawm woofers, nws qhov zaus qis feem ntau yog qis dua li ntawm lub thawv hauv pem teb, thiab nws lub zog nqa thiab cov zis suab siab kuj me dua, uas yog tsim rau siv nyob rau hauv ib qho chaw me me mloog; Raws li qhov nqaim bandwidth ntawm kev ua si, muaj cov neeg hais lus broadband thiab cov neeg hais lus nqaim. Cov neeg hais lus feem ntau yog tsim los npog Cov zaus band kom dav li qhov ua tau yog tus hais lus dav. Feem ntau hom kev nqaim-band hais lus yog lub subwoofer (subwoofer) uas tshwm sim nrog lub tsev ua yeeb yam, uas tsuas yog siv los kho cov zaus ultra-low zaus mus rau qhov nqaim heev; Raws li seb puas muaj lub tshuab hluav taws xob built-in, nws tuaj yeem muab faib ua cov neeg hais lus tsis txaus ntseeg thiab cov neeg hais lus nquag, cov qub tsis muaj lub suab nrov nrov thiab tom qab muaj. Tam sim no, feem ntau cov neeg hais lus hauv tsev tsis muaj zog, tab sis subwoofers feem ntau ua haujlwm.

2. Taw qhia rau Suab

Lub suab hais txog lub suab uas tsis yog tib neeg cov lus thiab suab paj nruag, suav nrog cov suab ntawm ib puag ncig ntuj, suab ntawm cov tsiaj, suab ntawm cov tshuab thiab cov cuab yeej, thiab ntau lub suab tsim los ntawm tib neeg kev ua. Suab tej zaum muaj xws li lub hwj chim amplifier, cov khoom siv peripheral (xws li compressor, effector, equalizer, VCD, DVD, thiab lwm yam), hais lus (hais lus, hais lus), tov khoom, microphone, cov khoom siv, thiab lwm yam ntxiv rau ib txheej. Ntawm lawv, hais lus yog cov khoom siv suab nrov, hais lus, subwoofer, thiab lwm yam. Ib tus hais lus suav nrog peb lub suab nrov, siab, qis, thiab nruab nrab, peb tab sis tsis tas peb. Kev txhim kho keeb kwm ntawm kev siv tshuab tuaj yeem muab faib ua plaub theem: electron tubes, transistors, integrated circuits, thiab field effect transistors.

Audio components:

Cov khoom siv suab tej zaum muaj xws li lub zog amplifiers, cov khoom siv peripheral (xws li compressors, teebmeem, equalizers, exciters, thiab lwm yam), hais lus (hais lus, hais lus), mixers, suab paj nruag (xws li microphones, suab paj nruag, VCD, DVD) tso saib thiab lwm yam, ntxiv rau ib txheej.
