Zoo acoustics: Specifications thiab cov qauv

Zoo acoustics hnub no - yog tsis tsuas yog ib tug qhia ntawm cov nyiaj txiag zoo, tab sis pov uas kos npe ntawm kev nkag siab nyob rau hauv technology thiab cov nyob rau ntawm zoo saj. Music lag luam txhua txhua xyoo muaj ntau thiab ntau cov tshiab thiab paub cov qauv, thiab nrhiav ib yam dab tsi haum yog tej zaum nyuaj heev rau koj tus kheej.

Ntawm cov hoob kawm, koj yuav tau mloog koj nyiam cov suab paj nruag yuav siv tau thiab "gramophone yawg", tab sis nws yog tsis zoo li nws yuav nthuav qhia qhov volume thiab clarity ntawm lub suab palette, uas yog tau mus rau kis high-zoo hais lus. Yuav ua li cas systems yog zoo tagnrho rau cov tsev, thiab cov uas rau ib lub tsheb?

Yuav ua li cas nws tag nrho cov pib

Tus thawj apparatus rau cov ntaubntawv povthawj siv thiab tu tub tu kiv los tshwm nyob rau hauv lub lig 19th caug xyoo. Lawv tsis ua hauj lwm nyob rau hauv hluav taws xob thiab mechanically. Ib tug piv txwv ntawm no yog lub Edison Phonograph (1877), uas kaw lub suab nrog ib rab koob zog, uas ib tug membrane. Tsab ntawv tsa suab tshwm sim nyob rau lub nruas, tus coated quav ciab los yog ntawv ci. Ces lub koob tsiv raws li txoj kev twb npaj. Yog li ntawd nws suab.

Nyob rau hauv qhov chaw ntawm ib tug Phonograph cov ntaub ntawv uas ua ntawv tuaj. Lub hauv paus ntsiab lus ntawm cov lag luam tseem zoo li qub, tsuas es tsis txhob ntawm ib tug nruas siv lacquered dial. Gramophones, phonographs thiab ces maj mam kis thoob plaws lub ntiaj teb.

txhob

Qhov teeb meem ntawm hluav taws xob siv rau lub suab tu tub tu kiv yuav qhib. Rov qab nyob rau hauv 1824 Ernst Siemens (creator ntawm lub eponymous ruaj) Ib qho kev qhia ntawm tus dais, qhov twg ib tug tshwj xeeb kauj winding tsiv nyob rau hauv tus ntawm ib tug hluav taws xob tam sim no, thiab nws deeg ua lwm lub suab. Txawm li cas los, tus tsim yuav nyob rau hauv kev tshawb xav kom txog rau thaum 1915. Thaum no tsim tau tsis tau npaum li cas los ntawm engineers ntawm Tswb (inventor ntawm tus xov tooj). Tsis ntev, txoj kev yog dai kom zoo nkauj nrog horn loudspeakers. Tab sis cov ntau yam lawv tau tsawg.

Qhov tiag txhob nyob rau hauv acoustics los ua electrodynamic radiator los ntawm lub American lub tuam txhab "General Electric". Nws diaphragm ua nyob rau hauv ib tug ntau yam ho saum toj no nws cov zaus. Lub apparatus siv rau loudspeakers Radiola Model 104 thiab radios Radiola 28. Nyob rau hauv 1927 godu suab zoo zoo los ntawm cov kev taw qhia ntawm lub taub hau nyob rau hauv lub tsim ntawm ib tug mus tas magnet loudspeaker. Txij li thaum uas lub sij hawm, muaj ib ntau txog cov kev hloov los ntawm tus tham, tab sis lub operating hauv paus ntsiab lus tseem zoo li qub.

emitter

Niaj hnub nimno acoustic system tsim rau audio playback thiab muaj acoustic tsim thiab kev hais lus. Raws li cov xov tooj ntawm hais lus paub qhov txawv ntawm ib leeg-band thiab multiband pab kiag li lawm. Tsim emitter kom meej meej reproduces lub suab ntawm ntau yam frequencies, nws yog ib qhov nyuaj, yog li ib leeg-band system twb tsis kis.

Nyob rau hauv multiband pab kiag li lawm, lub suab frequencies raug muab faib ua ob peb bands sib tshooj. nws dynamic lub taub hau yog tsim los rau txhua band. Nws yog zoo li ib tug ntaus ntawv yog vim high-zoo hais lus.

Classification hais lus

Tag nrho cov hais lus raug muab faib ua kom nquag plias thiab passive (rau kev twb kev txuas mus rau ib qho amplifier), txee thiab hauv pem teb (nyob rau hauv loj), uas tsis muaj nqi, Hi-Fi, High-End-class (tus nqi).

Tus ntaus ntawv muaj xws li passive sonar transducer thiab crossover, ib tug sab nraud amplifier. Supplemented los ntawm active nrog hwj chim amplifier. Ua-nyob rau hauv amplifier yam nyiaj vim hais tias muaj yog tsis muaj yuav tsum tau mus yuav ib tug ntxiv installation. Txawm li cas los, yog hais tias tus hais lus system yog ntsia ntawm ib tug tej yam siab, lub amplifier txij nkawm tsis yooj yim. Cov haib tshuab Acoustic amplifiers ntsia tau rau hauv txhua chav tsev, thiab nws yuav tsum tau ob khoom siv fais fab. Raws li, qhov nqi nce thiab tus ntaus ntawv.

Noj rau hauv tus account tag nrho cov subtleties ntawm ntaus ntawv siv cov active acoustic tshuab haum rau tus kheej computers, thiab saib nyob rau hauv lub studio voicing discotheques thiab me me venues.

Nyob rau hauv ib tug nyias muaj nyias ib qeb yog tag nrho cov-huab cua acoustics system. Lawv ua hauj lwm nyob rau hauv cov huab tej yam kev mob, nrog sai kub hloov. Raws li zoo raws li txoj kev ua neej-class systems uas muab kom tsim thiab zoo suab.

acoustic tsim

Ua loudspeakers sawv cev los ntawm ntau cov embodiments. Nws kuj yuav raug kaw los yog qhib lub thawv. Cov yav tas muaj xws li acoustic cov ntxaij vab tshaus los yog shields, raws li zoo raws li thiaj li hu ua "active lub cev". Tej zaum clearance Jensen-Onken, thiab qw nrov nrov, thiab Laub rub, thiab ib tug labyrinth system. Nyob rau hauv tas li ntawd, tej zaum nws yuav tsum tau siv "acoustic lens" los yog Helmholtz resonator.

cov ntaub ntawv uas

Qhov kev xaiv ntawm cov lus, nyob rau hauv tas li ntawd kev yam ntxwv yog ib qho tseem ceeb thiab cov khoom uas cov ntaus ntawv yog ua los. Vim hais tias nws kuj muaj feem xyuam rau lub suab zoo thiab them tus nqi ntawm lub system. Corpus txhua feem ntau yog ua los ntawm cov ntoo, yas thiab cov hlau. Nyob rau hauv lwm yam lus, lub "lub cev" ntawm sab yuav tsum txhav mus ntxaum dej / muaj kev cuam tshuam suab tsis ntawm ib tug tej yam hwj huam, zaus.

yas siv rau cov nyiaj txiag kev xaiv. Txhua yam ntaub ntawv yog heev tswv yim, lawv muaj feem ntau siv rau tus kheej computers. Txawm li cas los, ib tug drawback ntawm cov yas. Nws rattles tawm ib tug loj suab siab (volume). Txawm hais tias muaj cov qauv ntawm cov lus, lub cev uas yog ua los ntawm laminated yas, ntau resistant mus rau high hwj chim suab.

Yooj Yim, zoo ceev thiab hardness muaj hlau casings tham, thiab ntau yeej, lawv yog ua los ntawm txhuas alloys. Aluminium nws tus kheej thiaj li resonance thiab pab txoj kev kis tau tus mob ntawm lub suab frequencies. Oxidation "volatile hlau" tiv thaiv tshwj xeeb tsis muaj kob zaj duab xis. Xws li yuav siv tau raws li ib tug tag nrho-huab cua.

Tab sis qhov zoo tshaj acoustics muaj ib tug ntoo nkoj. Qhov tseeb tiag mas, xaiv ib tsob ntoo ua ntej txiav, ces sawv lub sij hawm kom txog rau thaum nws dries lawm. Needless ntau lawm thiab ua nqa mus qhov chaw yuav luag nkaus los ntawm txhais tes. Cov khoom tsis yog ib txwm muaj, li ntawd, feem ntau siv plywood, MDF, particle board. Cov khoom muaj zoo heev yam ntxwv tsis tau dais overtones absorbs suab deeg, muaj ib tug kho tshuab rigidity, etc. Lub nras thiab tiv thaiv kom txhob ya raws haum coloring los yog veneer cladding.

Ib txhia manufacturers siv uas tsis yog-tus qauv ntaub ntawv. Piv txwv li, dej tsaws tsag lub tuam txhab tsim cov vaj tse nyob txhua ntawm cov iav.

AU Housing

Xaiv cov lus qhia uas tau nkag mus rau hauv ib tug stupor txhua. Thiab nws tsis yog txawm nyob rau hauv zoo thiab tus nqi, thiab nyob rau hauv ib tug ntau yam ntawm manufacturers thiab cov qauv. Zoo acoustics rau lub tsev yog xaiv los ntawm cov nram qab no algorithm:

• Yog xav tau pib yog los txiav txim yuav ua li cas cov tsos thiab luaj li cas ntawm cov system yuav tsum muaj hais lus. Tsos nyob ntawm koj tus kheej saj thiab qhov luaj li cas yuav tsum ua raws li cov chav tsev nyob qhov twg tus ntaus ntawv yuav tsum tau nyob.
• Xav ntsoov txog cov lus qhia loj yuav tsum tau coj mus rau hauv tus account thiab cov acoustic thaj chaw ntawm lub tsev thiab hais lus. Tej zaum medium-qhov loj qhov me systems yog haib heev, nws tsis yog haum rau ib tug me me chav tsev.
• Zoo acoustics muaj ib tug ntoo nkoj, tab sis nws yuav tsum tau muab ib lub caij nyoog thiab lwm yam cov ntaub ntawv. Lawv lub zog kuj "txhawb" lub suab.
• Tus nqi thiab muaj kev ntaub ntawv. Nws paub meej qhov tseem ceeb cov yam ntxwv: rhiab heev loudspeaker (tob ntawm 90 dB), lub ntau zaus (20 Hz-20 kHz), tus xov tooj ntawm bands (ob los yog peb), lub AC kuj (4,6-8 ohm) thiab cov hluav taws xob hwj chim (Housing 50-100 W).
• Thaum kawg, saib cov xaiv system. Nyob rau hauv cov ntaub ntawv no, lub amplifier yuav tsum muaj ib tug multi-band equalizer, thiab ib tug laus tswj. Tej zaum kev muag khoom pheejyig npaum licas cunning nyob rau hauv kev siv ntawm cov amplifier.
• Tseem ceeb thiab suab paj nruag rau high-zoo acoustics. lub suab qhov twg los yuav tsum tau CD / DVD-neeg uas ua ntawv thiab tsav hom (CD-hom). Zoo music mus ntsuam xyuas lub acoustics yuav tsum suab sib npaug zoo nyob rau hauv txawv ntim ntau ntau.

AS rau cov tsheb

Zoo acoustics nyob rau hauv lub tsheb - tsis muaj tsawg rhiab qhov teeb meem. Manufacturers thiab advertising ib tug ntau, tab sis yuav ua li cas los xaiv tus ib txoj kev? Ntawm cov hoob kawm, txoj cai cia siab rau koj tus kheej saj nyob rau hauv cov suab paj nruag: suab ntuj quab yuam los yog domination ntawm lub ntses bass thaj tsam. Tab sis muaj ntau cov kev tsis.

• Nws yog ib nqi hmoog rau puab. Dua li, roj hmab es Ntaub txheej.
• Installation. Pem hauv ntej rooj nyob rau hauv lub tsheb mounted acoustic diluted nrog Shchelkova beeper (tweeters). Lawv muab mos mos, tus suab. Qab lub alarm kuj hais lus (17-20 cm). Lub pem hauv ntej hais lus me nyuam siab thiab nruab nrab frequencies, tom qab - tsis muaj frequencies.
• Hais lus yuav tsum tau ib tug podium, thiab nyob rau hauv lub qhov rooj - shumoizolyatory.
• Xeem point - zoo suab paj nruag mus ntsuam xyuas lub acoustics. Dua me ntsis nqi muaj CD-hom. Yog li ntawd, nws yog preferable mus ntsuam xyuas lub system. Cov MP3 thiab MPEG hom siv compression, raws li ib tug tshwm sim, zoo yog poob.

Hais txog manufacturers

Ntawm cov tuam txhab uas muag muab kev koom tes nyob rau hauv cov creation ntawm acoustic systems, muaj ntau ntau txoj kev ntseeg zoo thiab lub sij hawm-mus soj ntsuam. Yamaha, Microlab, Cabasse, JMLab, Piega. Lub German ruaj Tswb Suab yog paub tias yuav siv ib tug ob txheej tam yas nyob rau hauv qhov siv thiab ua casings. Ceev thiab hardness lawv tshaj txawm ntoo. Lwm sab saum toj-nqis siab tshaj Chaw tsim tshuaj paus ntawm AC yog Gemme Suab. Rau cov qauv siv DSP thiab haib dab.

Zoo tsheb hais lus manufactured los ntawm: Focal, Infinity, Hertz, Morel, Magnat, raws li zoo raws li "luminaries» Panasonic technology, Pioneer, Kenwood.

Ua koj tus kheej

Yog hais tias tus nqi qis kev xaiv tsis txaus siab nrog qhov zoo tshaj, thiab nws kim heev hais lus tsis muaj nyiaj txaus, koj muaj peev xwm sim los tsim thiab tsim lub system koj tus kheej. Yuav ua li cas yuav ua rau high-zoo li hais lus?

Heev yooj yim. Nws yuav tsum tau tsis tsuas lub sij hawm thiab miv, tab sis kuj paub txog tej yam kev pab cuam. Piv txwv li, los ntawm xam los ntawm acoustic tsim, txoj hauj lwm ntawm tus tham nyob rau hauv pem hauv ntej vaj huam sib luag thiab ua ke nrog ntawm tsob ntoo rau ob, peb-txoj kev system. Rau lub chaw ua khoom ntawm ib kem yuav siv lub hlis.
