Cheebtsam ntawm Multimedia Speaker Driver
Diaphragm:
Lub diaphragm muaj lub khob hliav qab thiab lub hau plua plav (dome). Nws ua hauj lwm raws li lub loj movable membrane tsim los oscillate rov qab thiab tawm raws li lub suab teeb liab waveform. Raws li lub diaphragm txav mus rau pem hauv ntej thiab rov qab, nws feem cuam tshuam thiab rub tawm cua, ua rau compression thiab tsis tshua muaj nyob hauv huab cua / nruab nrab, yog li nthuav tawm suab nthwv dej los ntawm huab cua / nruab nrab.
Kev ncua:
Lub ncua kev kawm ntawv txuas lub diaphragm mus rau lub tsev / pob tawb ntawm tus neeg hais lus. Nws pab txhawb tus nqi ntawm diaphragm mus ncig ua si thaum tuav lub diaphragm thiab lub suab coil nyob rau hauv lawv qhov tsim nyog ntawm kev txav. Qhov no suav nrog kev txhawb nqa kev txav raws Z-axis thaum txwv kev txav hauv X thiab Y-axes.
Ib puag ncig:
Lub puag ncig, tseem hu ua lub hauv ntej ncua kev kawm ntawv, yog ib lub nplhaib-zoo li tus tivthaiv uas txuas lub khob hliav qab / diaphragm mus rau lub pob tawb / chassis ntawm tus hais lus tsav tsheb. Raws li ib feem ntawm kev ncua, ib puag ncig pab hauv kev tswj lub khob hliav qab, tswj kev txav sab nraud thiab sab hauv ntawm lub khob hliav qab / diaphragm.
Kab laug sab:
Cov kab laug sab ua rau sab hauv ntawm tus hais lus raug tshem tawm. Nws lub luag haujlwm tseem ceeb yog ua kom lub suab coil nyob rau hauv txoj haujlwm, tso cai txav raws Z-axis thaum txwv kev txav mus los hauv X thiab Y axes. Yog tsis muaj kab laug sab, yuav muaj kev pheej hmoo tseem ceeb ntawm lub suab coil tsoo thiab / lossis ua raws li cov hlau nplaum.
Lub Suab Coil:
Lub suab coil yog lub kaw ntom nti (feem ntau cylindrical-puab) coil ntawm cov xaim hluav taws xob. Nws yog nruab nrog cov hlau lead uas txuas rau qhov kawg thiab dhau los ua ib feem ntawm lub voj voog uas lub teeb liab AC hla dhau.
Magnetic Structure:
Cov qauv hlau nplaum tsim kom muaj qhov sib nqus ruaj khov nyob rau hauv tus neeg tsav tsheb, tshwj xeeb tshaj yog nyob ib puag ncig lub suab coil. Raws li qhov sib txawv ntawm qhov sib nqus induced hla lub suab coil ntawm AC suab teeb liab, lub kauj sib cuam tshuam nrog cov hlau nplaum tas mus li thiab oscillates txheeb ze rau lub suab teeb liab waveform.
Magnet:
Cov hlau nplaum tseem ceeb yog lub hauv paus ntawm tus neeg hais lus tsav tsheb sib nqus (cov ncej ncej tsuas yog txuas cov ncej sib nqus ntawm lub ntsiab hlau nplaum).
Sab saum toj Pole Plate:
Cov ncej saum toj kawg nkaus txuas rau ib tus ncej hlau nplaum ntawm cov hlau nplaum mus rau sab nrauv ntawm lub suab coil. Yog hais tias lub phaj saum toj kawg nkaus nyias nyias, tus neeg tsav tsheb yuav poob efficiency thiab muaj kev saturation / distortion, thaum yog tias nws tuab heev, cov lus teb ntawm tus neeg hais lus yuav raug kev txom nyem.
Yawg:
Cov ncej ncej hauv qab thiab nce mus txog ncej ncej feem ntau hu ua ua ke ua tus quab. Cov khoom no, nyob rau sab nraum qab ntawm lub suab nrov, nthuav tawm cov lus sib nqus sib nqus mus rau sab hauv ntawm lub suab coil.
Pob tawb:
Lub pob tawb, tseem hu ua chassis lossis vaj tsev, yog lub tsev nyob ruaj khov uas txuas mus rau cov qauv hlau nplaum nyob hauv qab, ib puag ncig ntawm sab saum toj, thiab kab laug sab nyob rau hauv nruab nrab.
Hom Tsav Tsheb rau Multimedia Speakers
Cone Hom Tsav Tsheb:
Nrog conical zoo li tus diaphragms, qhov no yog hom tsav tsheb feem ntau siv. Diaphragms, feem ntau hu ua cone "paper," tau ib txwm ua los ntawm daim ntawv pulp. Txawm li cas los xij, tam sim no muaj ntau yam khoom siv. Dhau li ntawm daim ntawv pulp, cov khoom siv feem ntau suav nrog PP (polypropylene) thiab carbon fiber. Cov qauv no pom muaj ntau daim ntawv thov, npog tag nrho cov tsav tsheb uas muaj peev xwm rov tsim dua tag nrho lub suab spectrum, woofers rau kev tsim suab bass thaj tsam, nruab nrab tsav tsheb rau nruab nrab zaus ntau, thiab tweeters rau siab zaus.
Dome Type Drivers:
Diaphragms tuaj yeem ua tau zoo li lub dome, nrog lub suab nrov ncaj qha los ntawm lub domes. Qhov zoo ntawm hom kev tsav tsheb no yog nws txoj kev taw qhia zoo heev. Nws yog feem ntau siv rau nruab nrab thiab siab zaus luam tawm. Ntau hom dome tweeters muab kev pab cuam qis dua piv rau horn-type tweeters, ua rau lawv tsim nyog rau kev tsim 2- txoj hauv kev. Dome tweeters tuaj yeem muab faib ua ob pawg raws li cov ntaub ntawv dome: hom dome mos, uas siv cov ntaub ntawv mos xws li silk, paj rwb, lossis polyester zaj duab xis, thiab hom dome nyuaj, uas siv cov ntaub ntawv nyuaj xws li txhuas lossis titanium.
Horn Type Drivers:
Hom tsav tsheb no yog tus cwj pwm los ntawm lub horn txuas rau pem hauv ntej ntawm lub diaphragms. Nws daim ntawv thov raug yog kev tsim tawm ntawm nruab nrab thiab siab zaus ntau yam. Acoustic loaded horns muab cov tsav tsheb no nrog kev ua haujlwm siab thiab ua haujlwm zoo.
Speaker Driver Materials siv rau kev tsim khoom
Aluminium:Feem ntau ntawm cov hlau domes siv aluminium diaphragms. Aluminium muaj qhov tsis tshua muaj siab tawv-rau-qhov hnyav piv tab sis cov yam ntxwv tsis zoo damping. Qee cov neeg muag khoom kuj tau kho cov hlau los yog siv cov txheej txheem los txhim kho nws cov yam ntxwv damping.
Titanium:Titanium yog me ntsis hnyav dua li txhuas rau qhov sib npaug ntawm dome. Txawm li cas los xij, nws muaj zog ntau dua li aluminium thiab muaj me ntsis zoo dua sab hauv damping. Nws kuj tseem kim dua. Raws li nrog txhuas, tshuaj lom neeg los yog ceramic nto kho xws li "Tioxid" los yog coatings qee zaum siv los txhim kho damping.
Npuag kho:Feem ntau txhob lo lo ntxhuav, tab sis lwm yam ntaub ntawv kuj tseem siv tau. Cov ntaub qhwv tes yog siv los ua cov khoom ntawm kev xaiv hauv qee qhov kev hwm tshaj plaws tweeters hauv high-end suab tshuab. Npuag domes muaj siab sab hauv damping, thiab lawv qhov sib zog-rau-hnyav feem ntau yog nyob ntawm cov khoom siv los kho cov ntaub.
Beryllium:Siv tsuas yog nyob rau hauv kev tsav tsheb, beryllium yog qhov kawg hlau siv rau hauv diaphragms. Nws qhov hnyav-rau-qhov hnyav piv yog qhov siab tshaj plaws ntawm cov hlau paub. Txawm hais tias nws tus kheej damping tsis yog qhov zoo tshaj plaws, nws qhov tawv nqaij feem ntau ua rau nws cov resonances zoo tshaj 50 kHz, obviating qhov yuav tsum tau rau kev kho mob tshwj xeeb. Beryllium kuj yog ib qho ntawm cov khoom kim tshaj plaws los ntawm kev tsim cov diaphragms.
Polymide:Polymide yog qhov kawg ntawm cov ntaub ntawv nyuaj dome. Nws yog siv nyob rau hauv ib qho kev pom zoo tsav tsheb, tus nqi qis 3/4 "dome tweeter los ntawm LPG.
Kevlar:Txawm hais tias Kevlar feem ntau yog siv rau hauv daim ntawv woven rau cov tsav tsheb loj, nws tseem ua rau ob lub Kevlar dome tweeters.
Ceramic:Peb tsim tweeters siv nyias aluminium oxide ceramic diaphragms. Siv kom raug, ceramic tuaj yeem yog cov khoom siv yuav luag zoo meej. Txawm hais tias nws tsis yooj yim li ntau xav, fabricating ceramic diaphragms haum rau siv hauv tweeters yog qhov nyuaj heev.
