hais lus tawg ntau zaus. Qhov no tshwm sim feem ntau los ntawm kev mloog nkauj rau lub sijhawm ntev ntawm qhov ntim siab, txij li cov neeg hais lus hauv tsev tsis tuaj yeem ua haujlwm ntev ntev ntawm lub zog siab tshaj plaws. Lawv kuj ua txhaum los ntawm kev siv hluav taws xob ntau dhau rau lawv, txwv tsis pub, los ntawm kev txuas mus rau lub suab nrov dhau. Tab sis qhov no tsis zoo li yuav qhia rau koj hauv khw. Lawv piav qhia tias lawv yog lub hwj chim, tab sis tsis muaj leej twg yuav qhia koj tias, ua haujlwm ntawm kev txwv ntev, lawv tuaj yeem tawg. Tab sis feem ntau lawv yuav ua haujlwm rau lawv lub sijhawm lav. Yog li ntawd, qhov nruab nrab layman thiab cov lus nug tshwm sim, yuav ua li cas kho cov neeg hais lus nrog nws tus kheej txhais tes, dab tsi, feem ntau, tawg nyob rau ntawd thiab nws tsis yooj yim rau tsuas muab pov tseg?
Dab tsi yog txhua yam
Cov neeg hais lus yog hom yooj yim ntawm xov tooj cua engineering. Lawv yog ib rooj plaub thiab hais lus tsim rau hauv nws. Ib tus neeg hais lus lossis, hauv txoj kev yooj yim, lub suab nrov, tej zaum ib qho. Tab sis nyob rau hauv ib tug ntau dua qauv, tej zaum yuav muaj ob peb. Yog ibCov neeg hais lus yog tib yam, uas txhais tau hais tias lawv zoo kawg nkaus rov tsim dua ntau qhov ntau zaus. Tab sis feem ntau muaj ntau yam sib txawv. Yog hais tias tus neeg hais lus muaj peb qhov sib txawv ntawm cov neeg hais lus, ces qhov loj tshaj plaws rov tsim dua qhov tsawg zaus, qhov nruab nrab - nruab nrab thiab qhov tsawg tshaj plaws, raws li nws feem ntau hu ua "tweeter" - high frequencies.
Yuav ua li cas kho cov neeg hais lus ntawm hom ib txwm muaj, uas yog, tsis muaj zog, uas tsis muaj lub suab nrov nrov? Nws nyob ntawm seb hom kev puas tsuaj tshwm sim. Txij li thaum nws yog ib qho yooj yim los kho cov ntaub ntawv tawg, peb yuav tsis nyob ntawm xws li nuances. Cia peb mus los ntawm kev sib tawg cuam tshuam nrog kev ua tsis tiav ntawm cov neeg hais lus, vim tsis muaj ib yam dab tsi cuam tshuam rau cov neeg hais lus zoo tib yam (tsis muaj zog) sib nrug ntawm lawv.
Plug
Ntau zaus nws yog cov ntsaws. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum tau lub nplhaib nrog ib tug multimeter. Nov yog yuav kho kab ke li cas hauv qhov no:
- Ua ntej, peb kuaj qhov teeb meem. Ua li no, ua ntej ntawm tag nrho cov, tshem lub hau los ntawm unscrewing lub fasteners.
- Peb muab lub multimeter (tester) rau ntawm lub suab nrov thiab, hloov pauv txhua qhov kev sib cuag ntawm lub ntsaws rau hauv qhov chaw ntawm cov khoom siv hluav taws xob los ntawm lub ntsaws rau ntawm lub rooj sib tham, peb nrhiav kev sib tw. Yog tias tsawg kawg yog ib qho ntawm cov neeg sib cuag tsis nrov, uas yog, tsis lees txais xub lossis tsis lees txais, ces qhov teeb meem yog nyob rau hauv cov xaim lossis hauv plug.
- Hloov cov hlau thiab lub ntsaws ua ke kom "lub taub hau tsis mob".
- Peb ntswj lub hau npog, kos, kho dua.
Cov hais lus tam sim no tsis muaj cov ntsaws. Yog li ntawd, koj yuav tsum tau hu xov tooj rau nws tus kheej los ntawm nias cov neeg sib cuag (clothespins) ntawm tus hais lus thiab ntawm lub amplifier. Yog tsawg kawg ib tug nyobhu, hloov cov xaim, thiab txhua yam nyob rau hauv kev txiav txim.
Tweeter tsis ua haujlwm
Hais rau lo lus nug ntawm seb puas tuaj yeem kho kab ke yog tias ib tus neeg hais lus hlawv tawm hauv nws, peb yuav teb - nws yog qhov ua tau. Tab sis nyob rau hauv cov ntaub ntawv ntawm "tweeter", uas yog, nrog ib tug tweeter, qhov no tsuas yog kho los ntawm kev hloov, vim hais tias xws li hais lus muaj ib tug kaw diffuser pob tawb thiab koj yuav tsum tsis txhob sim disassemble nws. Cov khoom no pov tseg.
Kev tsis hnov lus tau raug txiav txim. Yog hais tias tus neeg hais lus tau nres poking, uas yog, muab tawm ntau zaus, lossis tus hais lus sab saum toj muab lub suab nrov, ces qhov teeb meem yog nyob rau hauv "tweeter". Peb ua dab tsi:
- Qhib lub hau los ntawm unscrewing lub fixing screws.
- Tshawb xyuas qhov kev ncaj ncees ntawm kev sib txuas ntawm cov neeg hais lus tsawg zaus, uas yog, seb cov xov hlau puas tau poob ntawm cov neeg hais lus. Yog tias txhua yam zoo li qub, qhov teeb meem yog 100% hauv "tweeter" nws tus kheej.
- Peb unsolder cov conductors los ntawm nws, pom cov hlau nyob rau hauv ntxiv, uas nyob rau hauv lub rho tawm (muaj cov cim nyob rau sab nyob ze cov neeg sib cuag).
- Peb coj tus tshiab (lossis siv, tab sis ua haujlwm) tweeter hauv lub khw hauv xov tooj cua lossis los ntawm cov phooj ywg, yog tias ib tus neeg dag nyob ib puag ncig. Qhov loj tshaj plaws yog hais tias tus hais lus haum rau lub hwj chim. Nws yog qhov zoo tshaj rau coj nws nrog koj mus rau lub khw. Nyob ntawd, tib neeg, yog tias muaj dab tsi, yuav pom ib qho analogue loj.
- Muab tso rau hauv. Txhawm rau kom tus neeg hais lus ua haujlwm yam tsis muaj lub suab nrov ntxiv thiab muab lub suab zoo, nws yog qhov zoo tshaj rau muab tus neeg hais lus nyob ib ncig ntawm lub voj voog ntawm lub sealant, xyuas kom meej tias nws tsis poob ntawm lub cone funnel nyob rau hauv txhua rooj plaub.
- solder cov hlau. Ntxiv - mus ntxiv, rho tawm - rau rho tawm.
- Kaw cov kab npog los ntawm nruj txhua tus ntsia hlau.
- Kev kuaj xyuas. Txhua yam ua tau zoo heev.
mid-range tsav tsheb tsis ua haujlwm
Tus hais lus no tuaj yeem kho tau yog tias daim nyias nyias tuav lub khob hliav qab hauv qhov chaw tau tawm los lossis cov khib nyiab tau poob rau hauv lub voj voog ntawm cov hlau nplaum uas lub khob hliav qab khiav. Hauv qhov no, tus neeg hais lus hawb pob. Thiab yog tias tsuas yog ib qho ntawm peb tus neeg hais lus hawb pob, ces qhov teeb meem tsuas yog nyob hauv nws. Yuav ua li cas kho ib kab rau suab paj nruag nyob rau hauv cov ntaub ntawv no, peb yuav piav qhia hauv qab no. Yog tias koj tsis xav thab nrog kev kho tus neeg hais lus, tab sis xav hloov nws nrog lwm tus ntawm tib yam lossis nws cov analogue, ua tib yam li hauv rooj plaub ntawm "tweeter".
Faulty bass driver
Yog tus hais lus me me nyem raws li qhov yuav tsum tau ua, nruab nrab ib tus hu nkauj, thiab tsuas yog tus hais lus loj hauv qab hawb pob, teeb meem nrog nws tau daws tib yam li nrog tus hais lus nruab nrab. Kev tawg yuav zoo ib yam. Txhawm rau hloov nrog ib qho tshiab, tsuas yog yuav nws thiab ua raws li cov lus qhia saum toj no.
Kab laug sab sib cais (diffuser centering washer)
Yuav kho tus hais lus ntawm kab li cas yog tias lub tshuab ntxhua khaub ncaws tau tawg? Peb ua raws li cov lus qhia hauv qab no:
- Yuav kuaj pom qhov teeb meem, tshem lub npog.
- Unscrew tus hais lus teeb meem ntawm rooj plaub, tshem tawm cov xov hlau los ntawm nws. Yog tias muaj lub ntsaws rau lub rooj tsavxwm los ntawm tus hais lus, txiav nws.
- Tshuaj kab laug sab. Yog hais tias nws yog torn los ntawm lub cev ntawm lub pob tawb,nws yuav tsum tau glued nyob rau hauv qhov chaw. Qhov no yog ua nrog kev pab ntawm "Moment" kua nplaum los yog zoo li.
- Ua tib zoo ntxuav qhov chaw hauv lub voj voog uas cov membrane yog glued. Nyob rau hauv tsis muaj txoj kev yuav tsum cov khib nyiab nkag mus rau hauv lub qhov ntawm lub diffuser kauj, yog li nws yog qhov zoo tshaj rau soften lub qub kua nplaum nrog acetone thiab yooj yim so nws nrog ib daim ntaub.
- Cia qhuav.
- Peb nplaum lub tshuab ntxhua khaub ncaws hauv qhov chaw. Kom txog rau thaum cov kua nplaum hardens, nruab nrab lub diffuser. Thaum nias, lub kauj hauv lub qhov yuav tsum txav mus los ywj siab thiab yuav tsum tsis txhob ua suab nrov sib tsoo. Txwv tsis pub, tus hais lus kho yuav hawb pob.
- Tom qab 24 teev, koj tuaj yeem sib sau kem hauv qhov kev txiav txim rov qab, raws li dismantled.
- Txuas, kos. Yog tias txhua yam nyob rau hauv kev txiav txim, txaus siab rau. Yog hais tias nws hawb pob, txawm tias muaj cov khib nyiab nyob rau hauv lub qhov ntawm lub kauj, los yog lub coil winding nws tus kheej yog puas los ntawm kev sib tsoo ntawm phab ntsa rau lub sij hawm ntev tsis muaj kab laug sab. Tom qab ntawv nyeem.
Nyob rau hauv qhov sib txawv ntawm cov khib nyiab khib nyiab
Qhov no kuj kho tau, tab sis ntawm no koj yuav tau tinker ntev dua thiab tsis yog qhov tseeb tias koj yuav tuaj yeem tshem tawm cov diffuser zoo thiab ntxuav lub qhov los ntawm cov av, thiab muab nws rov qab rau cov kua nplaum.. Kuv tuaj yeem kho kab ke li cas hauv qhov no:
- Qhib lub hau.
- Solder (txiav) cov xov hlau thiab tshem tus hais lus.
- Peb siv cov paj rwb lossis lwm txoj hlua, muab tso rau hauv acetone thiab muab tso rau hauv ib puag ncig ntawm qhov haum ntawm sab sauv ntawm diffuser funnel mus rau lub pob tawb lub cev.
- Ua ib yam nrogcentering washer, txij li thaum lub diffuser yuav tsum tau dismantled kiag li.
- Thaum cov kua nplaum softens txaus, ua tib zoo rhuav tshem cov diffuser los ntawm sab saum toj ntawm lub pob tawb, thiab kab laug sab los ntawm nws lub voj voog.
- Tshem tawm lub diffuser thiab ntxuav lub qhov ntawm cov khib nyiab. Qhov no tuaj yeem ua tiav nrog compressor, lub tshuab nqus tsev, ntau yam khoom siv kho tshuab, xws li cov duab los qhia. Nyob rau hauv tsis muaj cov ntaub ntawv yuav tsum koj poke ib ncig ntawm lub qhov ntawm cov hlau nplaum nrog tej daim hlau. Yog tias koj khawb cov phab ntsa, tus neeg hais lus yuav squeak raws li lub kauj rub tawm tsam cov burrs.
- Thaum txhua yam huv si, peb sib sau tus neeg hais lus rov qab, raws li tau muab cais tawm.
- Tom qab muab cov hlau nplaum rau hauv lub qhov, ua ntej muab nws tso rau ntawm cov kua nplaum, lub diffuser yuav tsum ua tib zoo nyob nruab nrab kom tsis txhob hnov qab thaum lub diffuser raus. Lub kauj hauv lub qhov yuav tsum txav mus ntsiag to.
- Tom ntej, cia cov kua nplaum qhuav rau 24 teev, sib sau ua ke thiab sim. Yog tias txhua yam suab zoo, koj zoo heev. Yog tsis yog ces koj tseem zoo heev. Tsawg kawg lawv sim. Tab sis tus neeg hais lus yuav tsum tau hloov nrog tus tshiab.
Computer hais lus
Thiab yuav kho tus hais lus rau lub computer li cas, koj nug. Peb yuav teb. Cov neeg hais lus hauv computer yog txhua yam ua haujlwm, uas yog, nrog cov amplifiers built-in. Nyob rau hauv lawv, feem ntau, suab chips hlawv tawm. Yog hais tias lub hwj chim teeb yog nyob rau, ces lub hwj chim mov yog OK. Feem ntau yuav, dynamics lawv tus kheej nyob rau hauv kev txiav txim. Thiab koj yuav tsum tau solder thiab solder lub nti. Nws tuaj yeem hlawv tawm thiab tsis nyob ib leeg, nws tuaj yeem hlawv tawm tsis kam, capacitor, thiab lwm yam.
Vim peb tsab ntawv tau raug saurau cov neeg uas tsis paub txog xov tooj cua engineering, peb yuav tsis piav qhia txog yuav kho qhov kev tawg no li cas. Ntawm no nws yog qhov zoo tshaj plaws tig mus rau tus tswv. Kuv tuaj yeem tau txais kuv cov neeg hais lus kho lub computer nyob qhov twg? Ntawm txhua qhov chaw pabcuam. Txhua yam ua tiav sai thiab pheej yig. Tab sis, feem ntau, qee tus qauv hais lus raug nqi ntau heev uas nws yog qhov zoo dua los yuav cov tshiab, vim tias, txawm tias nws pheej yig npaum li cas, qee zaum lawv yuav siv ib nrab tus nqi ntawm cov neeg hais lus lawv tus kheej rau kev kho (yog tias nws tsis nyob hauv warranty).
