Refined simplicity los yog stubbornness tsim nyog ntawm ib tug zoo deed?
Loudspeaker technology tau hloov zuj zus tshaj li ib puas xyoo. Twb tau thaum pib ntawm nws cov keeb kwm, nws tau pom tias kev ua tiav ntawm tag nrho cov acoustic spectrum, nrog kev txaus siab tsawg distortion, los ntawm ib tus neeg hais lus (transducer) yog qhov nyuaj heev, yog tias tsis yooj yim sua. Nws tau muab tawm tias nws yog qhov tsim nyog los tsim cov suab nrov uas muaj cov transducers tshwj xeeb hauv kev ua qee qhov sub-bands.
Kev loj hlob tau mus rau hauv cov kev taw qhia no, thiab nrog nws 99% ntawm cov tuam txhab nrov nrov, tsim kom muaj kev nplua nuj ntawm ob-txoj kev, peb-txoj kev, plaub-txoj kev thiab txawm tias ntau txoj hauv kev, qee zaum dhau-txhaum, tshaj tawm, tshaj-tsim. - los yog invented. zoo li cov amateurs lawv tshaj tawm tias ntau "txoj kev" qhov kev npaj zoo dua tej zaum ... rau cov neeg xav li no. Txawm li cas los xij, cov kev daws teeb meem muaj txiaj ntsig zoo, nyob rau hauv uas tus naj npawb ntawm txoj kev thiab tus naj npawb ntawm cov transducers (tsis yog tib yam - yuav muaj ntau tshaj ib qho transducer nyob rau hauv txhua txoj kev, uas feem ntau yog cov ntaub ntawv nyob rau hauv LF seem) yog proportional rau qhov luaj li cas. qauv thiab nws cov kev npaj siv.
Yam tsawg kawg yog ob txoj kev
Qhov tsawg kawg nkaus yog suav tias yog qhov yuav luag pom tseeb yam tsawg kawg nkaus ob tog system, feem ntau muaj xws li midwoofer thiab tweeter. Xws li ib tug system, raws li high-zoo converters ntawm ob hom, muaj peev xwm ua hauj lwm nyob rau hauv yuav luag tag nrho cov ntau zaus. Txawm li cas los xij, nws yog qhov nyuaj dua kom ua tiav qib siab nrog nws, vim tias qhov nruab nrab-woofer, uas yuav tsum muaj txoj kab nruab nrab (kom muaj peev xwm tswj tau nruab nrab zaus), txawm tias nws tuaj yeem tuav cov ntses bass thaj tsam, nws tsis tuaj yeem nqus tau siab heev. lub zog nyob rau hauv qhov ntau, nws tsis tuaj yeem tsim cov ntses bass thaj tsam tib lub sijhawm kom tob thiab nrov. Raws li peb txhua tus paub, qhov qis tshaj plaws thiab lub zog siab yog cov neeg hais lus loj, uas, txawm li cas los xij, tsis tuaj yeem ua haujlwm li midwoofers, tab sis tsuas yog woofers, ob qho tib si vim lawv txoj kab uas hla loj dhau, thiab vim muaj lwm yam, ua rau lawv. ntau cumbersome. tsim nyog rau kev ua haujlwm qis, ntau dua li nruab nrab zaus; Raws li qhov tshwm sim, peb-band tshuab raug tsim, qhov nruab nrab frequencies tau ua tiav los ntawm lub converter tshwj xeeb - qhov nruab nrab.
Ib zaug "zoo"
Davis MV Ib - lawv zoo li ib tug, tsis muaj lus hais ntxiv lawm.
Cov kev cai ntawm qhov kev ua si uas tso cai rau koj los tsim cov suab nrov nrov tsis nruj, tab sis cov kev cai dav dav yog, raws li nws tau, tsim thiab siv los ntawm feem coob ntawm cov neeg tsim qauv - tau kawg, tsuas yog ua kom tiav, thiab tsis yog raws li qee qhov zaub mov txawv. Tab sis ib yam li muaj cov neeg uas nyiam tshaj tawm nrog "permeability" thiab nyuaj rau kev teeb tsa, muaj cov neeg uas tawv ncauj rau qhov yooj yim, siv zog rau kev siv. zoo tshaj plaws - ib leeg-txoj kev thiab ib-txoj kev hloov suab nrov. Yog li nrog ib tus neeg hais lus.
Tau kawg, peb paub zoo nrog cov neeg nyiam, feem ntau me me, khoos phis tawj lossis cov khoom siv nqa tau yooj yim uas tsis muaj qhov chaw lossis pob nyiaj siv los nruab ib qho kev hais lus ob-txoj kev. Yog li peb tsis ua haujlwm nrog ib tus neeg tsav tsheb (hauv txhua lub tso suab tso suab, ntev npaum li lub tshuab tso suab), feem ntau me me, ob peb centimeters ntev, uas tsis tau raws li cov qauv qub heev rau cov khoom siv hi-fi, tab sis nws tsis yog. khoom siv. uas thov lub npe no.
Ntau qhov nthuav ntau yog cov qauv tsim ib-txoj kev, uas, hauv kev xav ntawm lawv cov neeg tsim qauv thiab, hauv kev xav ntawm ntau tus neeg siv, tsuas yog yuav tsum tau ua kom zoo dua li ntau qhov kev sib tw, thiab tshwm hauv cov neeg tseem ceeb lub hom phiaj, ntawm tus nqi ntawm ob peb kaum txhiab tus zł.
Hauv qhov teeb meem tsis sib haum xeeb no, peb yuav sim ua lub hom phiaj. Muaj tseeb tiag, cov txheeb cais lawv tus kheej qhia tau hais tias ntau lub tshuab ntaus ntawv muaj txiaj ntsig ntau dua los ntawm cov neeg tsim qauv ntse thoob ntiaj teb, tab sis cia peb sawv ntsug rau "qhov zoo tagnrho ib sab." Yam tsawg kawg nkaus thiaj li yuav nco ntsoov cov neeg nyiam ntawm cov qauv tsim uas nyuaj heev uas multipath tsis yog qhov kawg ntawm nws tus kheej, tab sis yog qhov tsim nyog tu siab thiab xaiv qhov kev phem tsawg dua. Qhov xwm txheej yuav zoo siab dua yog tias tag nrho cov qhab tuaj yeem ua tiav los ntawm ib lub suab nrov, xws li faib cov qhab mus rau hauv subbands, i.e. Kev taw qhia ntawm electrostatic precipitators (crossover), distortion. Cov emissions ntawm ntau zaus bands los ntawm cov neeg hais lus nrov nyob ib sab ntawm ib leeg, tab sis tsis nyob rau tib lub axis (nrog rau kev zam ntawm coaxial systems, uas muaj lwm yam tsis zoo ...) ua rau muaj teeb meem ntxiv. Txawm li cas los xij, nws tau lees paub tias nrog cov kev xav tau zoo, qhov no yog qhov teeb meem tsawg dua li qhov yuav tsum tau siv rau ib tus neeg tsav tsheb. Nws yog ib qho zoo uas yuav tsum nco ntsoov tias nws tsis muaj txiaj ntsig los muab lawv ntau yam tsis tsim nyog - koj yuav tsum khaws "patency" nyob rau hauv vim li cas thiab cov kev xav tau ntawm cov qauv nrog cov haujlwm tshwj xeeb thiab cov phiaj xwm tsis zoo.
Nws yog tsis yooj yim sua los tsim ib tug zoo tagnrho-ntau tsav tsheb, tab sis txawm ib tug dlej (piv rau lub peev xwm ntawm cov neeg hais lus)
nws yuav tsum muaj kev mob siab rau, kev txawj ntse thiab kev siv cov ntaub ntawv zoo tshaj plaws. Lub 20 DE 8 tag nrho cov suab nrov (siv hauv MV Ib) suav nrog, nrog rau lwm yam, ib qho kim Alnico hlau nplaum system.
Qhov tseeb, qhov zoo tshaj plaws yuav yog ib lub suab nrov zoo tshaj plaws uas tshem tawm tag nrho cov teeb meem tshwm sim los ntawm multipath. Hmoov tsis zoo, xws li lub suab nrov, lossis txawm tias "yuav luag" lub suab nrov zoo li no, txawm tias siv zog tas li, tsis muaj nyob. Tag nrho, txawm tias cov neeg hais lus zoo tshaj plaws muaj qhov nqaim dua li cov hais lus nrov tshaj plaws, thiab lawv qhov kev ua tau zoo tshaj qhov tsis sib xws. Qhov no, txawm li cas los xij, tsis cuam tshuam rau qee tus neeg, vim tias tus kheej-hypnosis lossis cov khoom tiag tiag ntawm cov khoom siv hluav taws xob ntau dua tso cai rau lawv pom qee yam txawv hauv lawv lub suab, qee yam tshwj xeeb, thiab yog li ntawd, raws li cov kiv cua ntawm cov kev daws teeb meem zoo li no. , ib yam dab tsi zoo dua. Ntxiv mus, ib co nta ntawm ib sab circuits nyiam cov tswv ntawm lub raj amplifiers - i.e. feem ntau low-power amplifiers, uas yog li ntawd tsis xav tau lub suab nrov ntawm lub zog siab, tab sis nrog kev ua haujlwm siab. Qhov tseeb yog tias lub suab nrov tsis tas yuav tsum muaj lub zog siab, tom qab ntawd vim yog cov qauv tsim cuam tshuam nrog nws (piv txwv li, lub teeb me me lub suab coil), nws yooj yim dua rau nws kom ua tiav tsis yog kev ua haujlwm siab xwb, tab sis kuj yog ib qho yooj yim rau kev ua tiav. dav bandwidth. .
Ua raws li koj lub siab xav
Lub suab nrov nrov heev thiab siab heev tau tsim los ntawm Fabkis lub tuam txhab Davis thiab siv nyob rau hauv MV One loudspeakers. Lawv qhov kev sim, nyob rau hauv ib pab pawg ntawm peb tus qauv Fab Kis (lwm ob yog peb-band), ib txwm qhia txog kev tsim, suab thiab kev ntsuas ntsuas, tau tshaj tawm hauv Lub Rau Hli (6/2015) qhov teeb meem ntawm Suab. Koj tuaj yeem sib piv thiab tsim koj tus kheej lub tswv yim ... Ib qho nthuav, txawm tias tsis muaj lub raj xa hluav taws xob.
