Dab tsi koj yuav tsum paub thaum xaiv tsheb acoustics
Txheem
Kev xaiv ntawm acoustics rau lub tsheb yog deb ntawm txoj haujlwm yooj yim, vim qhov no yuav tsum muaj tsawg kawg kev paub txog kev xav ntawm lub tsheb suab. Tsis tas li ntawd, nyob rau hauv txhua rooj plaub, koj xav tau kev paub txog kev txhim kho thiab teeb tsa cov cuab yeej, vim tias tom qab kev teeb tsa tsis tu ncua, tus tswv ntawm acoustics yuav ntsib cov keeb kwm yav dhau, suab tsis zoo thiab lwm yam teeb meem.
Yuav kim acoustics tseem tsis tau muaj panacea rau cov teeb meem suab yav tom ntej. Kev ua haujlwm tag nrho ntawm acoustic systems tsuas yog ua tau yog tias lawv tau teeb tsa kev tshaj lij. Yog li, peb tuaj yeem txiav txim siab tias kev teeb tsa thiab kev teeb tsa ntawm tus neeg hais lus yog qhov tseem ceeb dua li nws cov nqi. Hauv tsab xov xwm no, peb yuav teb qhov twg acoustics xaiv, thiab yuav nrhiav dab tsi thaum yuav khoom acoustic.
Hom hais lus
Thaum xav txog lub suab twg los xaiv rau lub tsheb, koj yuav tsum xub xyuas seb hom neeg hais lus. Txhua tus hais lus rau lub tshuab suab feem ntau yog muab faib ua ob pawg - coaxial thiab tivthaiv.
Dab tsi yog coaxial acoustics
Coaxial hais lus yog tus hais lus, uas yog tsim los ntawm ntau tus neeg hais lus rov tsim ntau zaus. Nyob ntawm qhov crossover ua rau hauv kev tsim ntawm hom lus no, lawv feem ntau muab faib ua ob txoj kev peb, 4..5..6.. thiab lwm yam. Yuav kom paub seb muaj pes tsawg lub band muaj nyob rau hauv coaxial tham, koj tsuas yog yuav tsum suav cov neeg hais lus. Peb xav kom xyuam xim rau qhov tseeb hais tias peb bands txaus los tsim tag nrho cov suab frequencies.
Acoustics uas muaj 4 los yog ntau dua bands suab squeaky thiab nws tsis zoo nkauj heev los mloog nws. Qhov zoo ntawm coaxial acoustics muaj xws li yooj yim ntawm fastening thiab tus nqi qis.
Cov khoom siv acoustics yog dab tsi?
Cov khoom siv acoustics yog cov neeg hais lus sib txawv ntawm ntau zaus, uas nyob sib nrug. Cov neeg hais lus tshaj lij no yog lub suab zoo. Qhov no yog vim qhov tseeb hais tias cov neeg hais lus nrog ntau zaus tsis nyob hauv tib qhov chaw.
Yog li, koj tuaj yeem tau txais kev lom zem tag nrho los ntawm kev mloog suab paj nruag, raws li lub suab tau muab faib ua cov khoom sib cais. Txawm li cas los xij, koj yuav tsum them rau qhov kev txaus siab: cov neeg hais lus no raug nqi ntau dua li cov coaxial, thiab kev txhim kho cov khoom siv acoustics yuav tsum tau siv zog ntau dua.
Kev sib piv ntawm cov khoom siv thiab coaxial acoustics
Qhov zoo ntawm lub suab tsim tawm, tus nqi thiab kev yooj yim ntawm kev teeb tsa tsis yog txhua yam uas txawv ntawm coaxial acoustics los ntawm cov khoom siv. Lwm qhov sib txawv ntawm ob hom lus no yog qhov chaw ntawm lub suab hauv lub tsheb. Qhov tsis zoo ntawm cov neeg hais lus coaxial suav nrog qhov tseeb tias lawv ua rau lub suab nqaim. Cov neeg hais lus pem hauv ntej yog cov hais lus sib txuas. Cov zaus siab, yog tias lawv raug coj los ntawm ob txhais ceg, yog qhov nyuaj rau hnov, ua tsaug rau cov khoom sib cais, cov tweeters tau teeb tsa siab dua, piv txwv li, ntawm lub dashboard ntawm lub tsheb thiab qhia rau cov neeg mloog. Yog li, qhov nthuav dav ntawm lub suab nce ntau zaus; lub suab paj nruag pib ua si tsis yog los ntawm hauv qab, tab sis los ntawm sab xub ntiag, lub npe hu ua theem nyhuv tshwm.
Diffuser thiab suspension khoom
Ib qho kev piav qhia ntawm lub suab nrov yuav tsum muaj cov ntaub ntawv hais txog yam khoom uas lawv tau ua los ntawm. Cov ntaub ntawv hauv qab no tuaj yeem siv rau kev tsim cov diffusers: ntawv, polypropylene, backstren, titanium, magnesium, aluminium, thiab lwm yam.
Feem ntau yog cov ntawv diffusers. Nyob rau hauv tus txheej txheem ntawm lawv tsim, nplooj ntawv ntawm cov ntawv yog nias ua ke, tom qab uas lawv muab ib tug conical zoo. Tab sis nws tsim nyog hais tias, qhov tseeb, yuav luag txhua daim ntawv diffusers tuaj yeem raug ntaus nqi rau cov khoom sib xyaw, vim lwm cov khoom siv hluavtaws siv hauv cov txheej txheem ntawm lawv cov khoom. Eminent manufacturers yeej tsis qhia tawm cov ntaub ntawv twg yog siv, vim hais tias txhua tus ntawm lawv muaj nws tus kheej proprietary daim ntawv qhia.
- Qhov zoo ntawm daim ntawv cones suav nrog cov ncauj lus kom ntxaws, uas yog tsim los ntawm kev ua haujlwm zoo hauv damping. Lub ntsiab tsis zoo ntawm daim ntawv cones yog suav hais tias yog lawv lub zog tsis tshua muaj zog, vim tias lub suab lub zog hauv lub suab yog txwv.
- Cov diffusers ua los ntawm polypropylene muaj cov qauv tsim ntau dua. Lawv yog cov yam ntxwv ntawm lub suab nruab nrab, nrog rau zoo heev impulsive yam ntxwv. Nyob rau tib lub sij hawm, xws li diffusers yog resistant rau txhua yam thiab atmospheric influences tshaj daim ntawv diffusers.
- Diffusers ua los ntawm titanium thiab txhuas pib ua nyob rau hauv lub teb chaws Yelemees nyob rau hauv lub 80s. Lawv cov khoom tsim tau raws li kev siv tshuab nqus tsev vacuum. Domes ua los ntawm cov ntaub ntawv no yog qhov txawv ntawm lub suab zoo tshaj plaws: lub suab yog pob tshab thiab meej.
Nyob rau hauv xaus, nyob rau hauv seem no, kuv xav hais tias manufacturers tau kawm yuav ua li cas ua kom zoo acoustics los ntawm yuav luag txhua yam khoom, muaj txawm hais lus ua los ntawm noble hlau, tab sis lawv raug nqi ntau heev. Peb qhia koj kom xyuam xim rau cov neeg hais lus nrog lub khob hliav qab, nws muaj lub suab zoo heev, thiab tau raug sim los ntawm ntau tshaj ib tiam.
Thiab kuj tseem yuav tsum tau them sai sai rau cov khoom siv sab nraud ntawm lub diffuser yog ua los ntawm. Kev tshem tawm tuaj yeem ua los ntawm cov khoom siv tib yam li cov diffuser, lossis nws tuaj yeem yog cov khoom sib cais hauv daim ntawv ntawm lub nplhaib ua los ntawm roj hmab, polyurethane lossis lwm yam khoom siv. Ib qho ntawm qhov zoo tshaj plaws thiab feem ntau raug tshem tawm yog roj hmab. Nws yuav tsum nyob twj ywm linear tshaj qhov ntau ntawm kev txav ntawm lub suab nrov thiab yuav tsum tau hloov pauv raws li qhov no cuam tshuam rau cov zaus resonant.
Lub subwoofer yog tib tus neeg hais lus uas muaj peev xwm rov tsim dua cov zaus qis "Dab tsi yog qhov txawv ntawm qhov passive subwoofer thiab ib qho nquag."
Lub zog thiab rhiab heev ntawm acoustics
Ntau tus xav paub yuav ua li cas xaiv cov neeg hais lus rau lub xov tooj cua hauv tsheb, tab sis lawv tsis nkag siab tias yuav ua li cas los ntawm qhov tsis zoo li lub zog. Muaj ib qho kev xav yuam kev tias lub zog ntau dua, lub suab nrov yuav ua si. Txawm li cas los xij, hauv kev xyaum, nws hloov tawm tias tus neeg hais lus nrog lub zog ntawm 100 W yuav ua si ntsiag to dua li tus hais lus nrog ib nrab lub zog. Yog li, peb tuaj yeem txiav txim siab tias lub zog tsis yog qhov qhia txog lub suab ntim, tab sis ntawm kev ntseeg siab ntawm cov tshuab.
Qhov ntim ntawm cov neeg hais lus rau qee qhov nyob ntawm lawv lub zog, txawm li cas los xij, tsis ncaj qha cuam tshuam rau qhov ntsuas no. Nws ua rau kev nkag siab zoo rau lub zog ntawm lub suab tsuas yog thaum nws los mus yuav acoustics rau lub amplifier. Hauv qhov no, tsuas yog lub zog ntsuas (RMS) yog qhov tseem ceeb, vim tias lwm cov ntaub ntawv yuav tsis muab cov ntaub ntawv tseem ceeb rau tus neeg yuav khoom thiab tsuas yog ua rau nws yuam kev. Tab sis txawm tias RMS qee zaum muaj me ntsis ua rau qhov tseeb, yog li nws yog qhov ncaj ncees los hais tias lub hwj chim daim duab yog qhov tsis paub tseeb rau cov neeg hais lus muaj peev xwm.
Qhov luaj li cas ntawm cov hlau nplaum hais lus kuj yog dag, vim hais tias kim suab tshuab muaj cov hlau nplaum neodymium. Txawm tias muaj tseeb hais tias lawv yog unremarkable nyob rau hauv tsos, lawv cov khoom sib nqus yog me ntsis siab dua li cov hlau nplaum ferrite. Hauv kev xyaum, qhov no txhais tau hais tias lub suab ntawm yav dhau los muaj zog ntau dua, Vim lawv qhov me me, neodymium hlau nplaum systems kuj muaj qhov tob hauv qhov tob, uas ua rau lawv yooj yim installation hauv lub tsheb.
rhiab heev yog ib qho parameter ntawm lub tshuab suab uas qhia txog qhov siv ntawm lub suab siab. Qhov siab dua, lub suab nrov dua, tab sis tsuas yog tias cov neeg hais lus tau muab nrog lub zog tshwj xeeb. Piv txwv li, tus hais lus tsis muaj zog ua ke nrog lub suab nrov muaj zog tuaj yeem tsim lub suab nrov dua li tus hais lus siab. Chav ntsuas ntsuas rhiab heev yog decibel muab faib los ntawm qhov pib ntawm kev hnov lus (dB / W * m). rhiab heev yog cuam tshuam los ntawm qhov tsis xws li suab siab, kev ncua deb ntawm qhov chaw, thiab lub teeb liab zog. Txawm li cas los xij, nws tsim nyog sau cia tias nws tsis yog ib txwm tsim nyog los cia siab rau qhov ntsuas no, vim tias qee tus neeg hais lus tuam txhab ntsuas ntsuas qhov rhiab heev hauv cov xwm txheej tsis zoo. Qhov zoo tshaj plaws, rhiab heev yuav tsum ntsuas ntawm qhov deb ntawm tsis ntau tshaj ib meter nrog lub teeb liab ntawm ib watt.
Thaum xaiv cov neeg hais lus hauv koj lub tsheb, nug tus neeg muag khoom seb tus neeg hais lus no puas muaj qhov xav tau? Tsawg rhiab heev yog 87-88 db, peb qhia koj xaiv acoustics uas muaj rhiab heev ntawm 90-93db.
Kuj nyeem tsab xov xwm, "yuav ua li cas xaiv lub amplifier txoj cai rau koj lub kaw lus."
Hom
Lwm qhov kev pom zoo uas tuaj yeem muab rau cov neeg uas tab tom txiav txim siab xaiv cov chaw tsim khoom tshwj xeeb yog tsis txhob caum tus nqi qis thiab ceev faj thaum yuav cov neeg hais lus los ntawm cov tuam txhab tsis muaj npe. Txawm hais tias kev ntxias cov lus ntawm cov neeg muag khoom zoo li cas, koj yuav tsum tsis txhob them nyiaj rau cov kev ntxias no, vim nws yog ib txwm zoo dua tig mus rau cov tuam txhab uas tau tsim lawv tus kheej ntev hauv kev ua lag luam.
Lawv muaj ntau xyoo dhau los ntawm kev tsim cov neeg hais lus, muaj nuj nqis rau lawv lub koob npe nrov, thiab yog li tsim cov khoom zoo xwb.
Cov lus teb rau lo lus nug ntawm yuav ua li cas xaiv acoustics rau lub tsheb yog tsis yooj yim li, piv txwv li, kaum xyoo dhau los, vim hais tias muaj coob tus manufacturers nyob rau hauv lub lag luam (ntau tshaj 200). Lub dominance ntawm Suav acoustic systems ho nyuaj rau txoj hauj lwm. Tsis txhob tso tseg tag nrho cov khoom lag luam hauv Suav teb, vim tias nrog kev siv nyiaj nruj, kev yuav cov lus hais los ntawm Tuam Tshoj yuav tsis yog qhov kev txiav txim siab phem. Tab sis qhov teeb meem yog tias muaj coob tus neeg muag khoom tsis zoo nyob rau hauv kev ua lag luam uas tam sim no suab tshuab ua nyob rau hauv Suav teb raws li cov khoom lag luam los ntawm Asmeskas lossis European manufacturers. Hauv qhov no, tus neeg yuav khoom, uas tau txiav txim siab ob peb puas rubles, yuav yuav "branded" acoustics rau $ 100, thaum nws tus nqi tiag tsis tshaj $ 30.
Yog tias peb xav txog qhov kev ntsuas no raws li qhov tshwj xeeb ntawm lub suab, tom qab ntawd rau lub suab zoo dua nws pom zoo kom yuav cov suab hauv European (Morel, Magnat, Focal, Hertz, LightningAudio, JBL, DLS, BostonAcoustic, qhov no tsis yog tag nrho cov npe) . Peb kuj pom zoo kom koj tsis txhob yuav cov tuam txhab xws li (Tsis Paub, supra, Fusion, Suab max, calcel) Cov tuam txhab lag luam no muaj tus nqi tsis zoo, tab sis lub suab zoo ntawm cov neeg hais lus no tsim nyog. Hais lus tshuab los ntawm Sony, Pioneer, Panasonic, JVS, Kenwood kuj yog cov kev xaiv zoo heev, tab sis qee tus ntawm lawv cov tswv yws txog qhov nruab nrab lub suab zoo. Yog tias koj tab tom nrhiav kev sib xyaw ua ke zoo tshaj plaws ntawm cov khoom siv xws li tus nqi thiab qhov zoo, ces nws yog qhov zoo tshaj plaws hu rau cov tuam ntxhab uas tau hais los saum toj no.
