Hom tham: tsim, kev ntsuam xyuas, specifications

Nyob zoo hais lus los ntawm lub siab nqi ya tau ntev ceased mus yuav ib tug yooj yim kiag, ib yam ntawm cov thawv, ua ib lub suab nrog kev pab los ntawm ib khub tham. Engineers los ntawm xyoo mus rau xyoo, contrive, transforming lub lag luam thiab txhua unit rau hauv ib tug me me ua hauj lwm ntawm cov kos duab uas tsis txhua leej txhua tus muaj peev xwm tau rov qab. Muaj tshiab hom hais lus, txoj kev tshiab ntawm suab tso zis ntau zog variation thiab amplitude, thiab thiaj li nyob thiab thiaj li tawm. Thaum lub sij hawm, muaj ib tug tag nrho multicomponent qauv, piav txog qhov sib txawv hom ntawm tham. Ua tau, qhov no yuav tsum los sib tham nyob rau hauv lub nqe lus nram qab cov khoom.

Categorization tham

Yog li ntawd, yuav pib tsi tawm qhov yooj yim sib nrauj ntawd, dab tsi yog qhov hais lus, thiab xwb ces nrhiav seb yog dab tsi lawv muaj thiab yuav ua li cas txawv los ntawm txhua lwm yam.

Cov nram qab no hom ntawm hais lus:

• Txee thiab pem teb tshuab. Los ntawm lub npe nws yog ib qhov tseeb hais tias lawv txawv rau lub hauv paus ntawm sab hauv tsev installation thiab nyob rau hauv loj.
• Tsis tas li ntawd, hais lus yog distinguished los ntawm tus xov tooj ntawm bands (nyob rau hauv qhov tseeb, tus xov tooj tham) - los ntawm ib tug mus rau xya.
• Muaj dynamic, electrostatic, planar thiab lwm tus tham, nyob ntawm seb tus tsim ntawm tus hais lus, uas yuav tsis poob mus rau tog twg los qeb (tag nrho cov nyob rau hauv lub tswv yim ntawm engineers).
• Nyob rau hauv lub acoustic tsim vaj tse, txhua raug muab faib mus rau hauv lub nruab nrog rau kev qhib lub cev, kaw tsev nyob nrog ntses bass thaj tsam reflex tsim nrog ib tug acoustic labyrinth, thiab hais txog.
• Txhua raug muab faib ua kom nquag plias thiab passive nyob rau hauv lub xub ntiag ntawm cov kev audio amplifier.

Ib leeg-band thiab multiband hais lus

Ib leeg-band hais lus yog nruab nrog ib tug hluas emitter, thiab yuav ua li cas teem ib emitter rau ib tug zoo tu tub tu kiv ntawm tag nrho cov frequencies ib zaug yog tsis tau, manufacturers yuav tsum tau siv ntau ntau yam emitters configured.

Tseem muaj 2- Way acoustic system (3, 4). Nyob rau hauv xws systems, ntsia ob radiator. Ib assumes lub tu tub tu kiv ntawm tsawg thiab nruab nrab frequencies, thiab lub thib ob cov me nyuam xwb lub siab frequencies. Los ntawm no mus kom ze tus zoo tagnrho cov suab tshuav nyiaj li cas yog tiav nyob rau hauv ib tug 2-txoj kev hais lus system, tsis yooj yim sua siv ib zaug xwb hais lus (txawm yog hais tias nws yog heev zoo). Lub suab ntawm cov lus qhia no feem ntau yog txaus rau cov inexperienced cov neeg uas tsis hais tsis tau lus ntau tshaj systems, tab sis tseem muaj ntau tau xaiv, xws li 3-txoj kev system. 3-txoj kev hais lus systems faib ib zaug tag nrho peb hom frequencies ua ke. Ib radiator yog koom tu tub tu kiv ntawm tsawg frequencies, lub thib ob - siab, peb - nruab nrab. 3-txoj kev hais lus systems tshwm sim ntau dua lwm tus, vim hais tias nws yog ua tsaug rau qhov no tsim tiav lub siab tshaj plaws zoo playback frequencies audible los ntawm cov tib neeg pob ntseg.

Passive thiab active hais lus

Active thiab passive systems yog distinguished los ntawm lub xub ntiag ntawm ib ke hwj chim amplifier tsim txhua lawv tus kheej.

Active hais lus muaj ib lub hwj chim, li ntawd, lawv yuav tsum tau kev cob cog rua ncaj qha mus rau lub pre-amplifier ntawm interconnect, thiab txhua tus nyias muaj nyias kev kem yog noj los ntawm lub hwj huam mov tsis muaj ntxiv hwj chim qhov chaw.

Passive hais lus, tab sis yog nyuab dua ntaus ntawv, tsis tau muaj ntau ntau thiab yog ib feem rau cov neeg uas txaus siab rau high-zoo suab. Tej kab yog kev cob cog rua rau lub hwj chim amplifier los ntawm ib tug siab crossover. Cov kev twb kev txuas yog los ntawm txoj kev ntawm acoustic conductors. Muaj ntau manufacturers (lub tuam txhab) hais lus xav los tsim xws li txhua, ces lawv coj loj profits thiab cia engineers kom paub lawv hom phiaj ntawm lub suab. Nyob rau hauv tas li ntawd mus txog teeb meem nyob rau hauv lub installation, muaj kuj yog qhov teeb meem ntawm nyiaj txiag, vim hais tias ib tug zoo amplifier thiab hais lus cables yog ib tug ntau ntawm cov nyiaj, thiab yog tsis muaj lawv "zavedesh" xws li ib tug system.

Horn loudspeakers

Qhov no xyov hom lus. Lawv feature yog muaj nyob rau ntawm lub horn radiator installation. Qhov kom zoo dua ntawm xws txhua yog lub siab rhiab heev ntawm cov lus qhia. Qhov no ua rau lawv ib tug zoo meej complement rau cov uas tsis tau them nqi thiab muaj hwj huam raj amplifiers, tsis muaj peev xwm muab lawv cov tswv tsev txaus ntim. Cov hais lus yuav tsum tau muaj peev xwm tso kawm nyob rau hauv lub chav tsev nyob qhov twg lawv yuav tsum ua hauj lwm, tab sis yog koj noj ib pliag, nws yog ua tau mus cuag lub feem ntau muaj tiag thiab mob siab heev lub tso suab duab.

electrostatic hais lus

Cov systems yog distinguished los ntawm lawv tej yam txawv tsim. Es tsis txhob qhov classic zaj duab xis hais lus siv ntawm ib tug conductive khoom, uas yog rho mas raws sab. Lub hauv paus ntsiab lus ntawm cov lag luam yog raws li nram no: cov zaj duab xis yog noj mus rau ib tug lub suab teeb liab hauv ib lub zaus, thiab rau semiconductors flanking nkag nrog hluav taws xob (tus ntxeev txiav txim yog cai nyob rau hauv tej rooj plaub thaum ib tug hluav taws xob tam sim no yog txhab khoom mus rau conductive zaj duab xis). Nruab nrab ntawm lub zaj duab xis thiab cov semiconductor tsim ib qho electromagnetic teb thiab ib tug nce mus nce los teb. Vim hais tias ntawm no, muaj hloov mus hloov los nyob rau hauv cov zaj duab xis, uas reproduces lub suab tawg. Lub suab ntawm cov neeg hais lus yog ib co ncauj lus kom ntxaws, tseeb kis tau tus mob ntawm txhua zaus. Music mas yuav tsum tau ntau dawb thiab qhib. Ntawm cov ob peb drawbacks yog muab ib qho kev tsis txaus tus nqi ntawm ntses bass thaj tsam uas tsis tau kev ntawm qhov tob ntawm, tshwj xeeb tshaj yog thaum nws tawm los rau tej yam raws li hip-hop los yog mag.

central channel system

Raws li hais lus rau cinemas (tsev kawg) siv yog 5 poob lawm ntawm hais lus thiab ib tug subwoofer. Qhov no classic system, pov thawj thiab siv los ntawm feem ntau ntawm cov kiv cua ntawm zoo suab. Ib tug tseem ceeb ntawm no system yog ib qhov chaw hais lus uas reproduces ib tug yeeb yam dialogs thiab suab paj nruag tseem ceeb tawg tsam. Qhov no qhia kiag yog teem cai nyob rau hauv lub center. Ib txhia neeg siv nws nyob rau hauv hais lus rau koj lub computer, raws li saib ib tug yeeb yam rau nws.

Lub pem hauv ntej thiab nram qab lub hais lus

Lub pem hauv ntej system yog ib tug classic khub hais lus, tsim ib lub tso suab nyhuv. Tej kab feem ntau tsim ib tug tag nrho cov lus qhia rau cov computers (txij li thaum feem ntau tsis muaj dab tsi ntau yog yuav tsum tau). Thaum nws los txog rau lub tsev ua yeeb yam, nruab nrab ntawm ob sab pem hauv ntej hais lus (los yog ib tug TV) khoov chaw channel hais lus. Kev cia siab rau pem hauv ntej khub hais lus, koj yuav tsum sau qhov seem ntawm tus hais lus system 5.1, txij li thaum lawv cov me nyuam lub yooj yim array ntawm cov suab.

Lub rear ib feem ntawm lub cev - yog ob tug me me hais lus nyob qab lub saib. Lawv siv yog los tsis ua cas, tab sis lawv yeej ib txwm tuaj nrog cov 5.1 hais lus system rau siab tshaj plaws immersion nyob rau hauv cov cua ntawm kev ua si movie. Yog hais tias lub suab khiav ntawm cov zaj duab xis txhawb surround suab technology, tej txheej xwm thiab scenes nyob rau hauv cov zaj duab xis yuav ua si ib suab xwb lub rear hais lus (qhov no tshwm sim thaum ib tug neeg sneaks qab lub hero ntawm zaj duab xis). Thaum uas siv cov lus qhia sawv yuav siv lub system thiab computer tham.

subwoofer

Qhov no yog ib daim kem, uas muaj peev xwm tsuas ua si ntses bass thaj tsam thiab ntses bass thaj tsam. Feem ntau siv nyob rau hauv ua ke nrog ua khub txhua thiab complements hais lus system rau koj lub computer, raws li rau pem hauv ntej hais lus yuav tsis tau tiv nrog tag nrho cov suab ntau. Subwoofer theem qhov nqi koj tshuav ntawm cov lus system. Dig muag, subwoofer zoo ib yam li ib tug qub hais lus, tab sis nws tsim ib tug loj heev radiator nyob rau hauv lub meej. Lub subwoofer yog ntsia tau rau hauv ib lub ces kaum los yog nyob rau hauv ib tug computer rooj. Vim hais tias ntawm no, los ntawm txoj kev, feem ntau txom nyem cov neeg nyob ze.

Txee thiab pem teb hais lus

Tej zaj systems yuav tseem yuav hu ua desktop thiab pem teb (los yog computer thiab cov tsev ua yeeb yam). Txee rau ntawv hais lus coj mus ntau tsawg qhov chaw thiab tsis tau nyhav npaum li cas tsawg, uas txhais tau tias lawv yuav tsum tau muab teem dua. Piv txwv li, yog tias koj sau lub cev rau lub tsev, uas yuav tsum tau kev cob cog rua rau lub TV (los tsim suab tob), koj yuav muab tso rau saum txee kem txawm tias ib tug wardrobe (nws muab lub siab tshaj plaws cheeb tsam kev pab them nqi). Yuav kom neeg lub siab tshaj plaws tej zaum los ntawm cov compact hais lus kheev mounted rau ib tug tshwj xeeb acoustic khib.

Pem teb tshuab uas yog zoo dua suited rau cov loj chav (feem ntau hu ua hais lus rau movie theaters). Lawv teem loj hais lus, thiab lawv muaj pes tsawg mas nws txawv ntawm ib tug mus rau xya. Installation ntawm xws kab nyob rau hauv ib tug me me rau thaj tsam yuav ntxias ntev ntses bass thaj tsam boost thiab ntseeg tau hnov hum. Pem teb tshuab yog cov ntau ntau kim shelving thiab yuav tsum tau designers ntau npaum li cas xim nyob rau hauv cov lus teb thaum lawv tsim.

Ntses bass thaj tsam reflex hais lus

Fazoinvertor - lub qhov nyob rau hauv lub vaj tse, uas yeeb nkab yog lub puab yog ib feem ntawm sab. Nrog rau qhov no tsim, acoustics yuav muaj me tub uas tsis muaj frequencies uas yog muab tsis cuag rau cov pa hais lus tsis muaj reflex. Thaum tsim engineer yuav tsum xaiv cov kem lub cheeb thiab cov yeeb nkab ntev raws li lub zaus yuav tsum tau ua dua tom ntej no lub suab qhov twg los. Thaum lub sij hawm thaum muaj lub suab paj nruag playback, lub volume ntawm huab cua nyob rau hauv lub raj resonates thiab amplifies reflex playback ntawm uas zaus nyob rau hauv uas cov yeeb nkab inch tau chiv configured.
