Cov kab lus hais lus puas tuaj yeem siv rau lub zog?
Txheem
Kab lus no yuav muab cov ntaub ntawv tseeb txog kev siv cov kab lus hais lus los muab hluav taws xob.
Cov hluav taws xob feem ntau yog muab los ntawm cov xov hlau nrog tus neeg xyuas pib hauv, tib yam yog cov lus hais lus. Yog li, yog tias koj xav tias cov lus hais xov tooj kuj tuaj yeem siv los muab hluav taws xob, koj yuav yog, tab sis muaj qee yam koj yuav tsum xav txog.
Feem ntau, koj tuaj yeem siv tus hais lus xaim rau lub zog yog tias koj xav tau txog li 12V, tab sis nws nyob ntawm qhov loj ntawm cov xaim. Ib txoj hlua tuab los yog nyias nyias, raws li, hla ntau lossis tsawg dua tam sim no. Yog hais tias, piv txwv li, nws yog 14 gauge, nws yuav siv tsis tau nrog ntau tshaj 12 amps, nyob rau hauv cov ntaub ntawv no cov cuab yeej yuav tsum tsis txhob yuav tsum tau ntau zog tshaj li 144 watts. Kev siv sab nraum lub thawv no tuaj yeem tsim teeb meem hluav taws kub.
Mus nyeem ntawv kom paub ntxiv.
cov kab lus hais lus
Raws li lub npe qhia, hais lus xov hlau yog rau txuas cov khoom siv suab xws li amplifiers rau cov neeg hais lus.
Cov kab lus hais lus muaj ob txoj hlua, ib yam li ob txoj hlua hluav taws xob. Tsis tas li, zoo li cov xaim hluav taws xob tsis tu ncua, lawv tuab txaus los tiv thaiv tshav kub los ntawm lub zog poob, tab sis lawv ua haujlwm ntawm qhov qis dua tam sim no thiab qhov ntsuas hluav taws xob. Vim li no, lawv feem ntau tsis muaj rwb thaiv tsev txaus. (1)
Cov kab lus hais lus txawv li cas?
Tam sim no koj paub tias cov kab lus hais lus tsis txawv ntau ntawm cov xov hluav taws xob niaj hnub siv los muab hluav taws xob, koj yuav xav tias lawv txawv li cas.
Ob hom hlau no ntau dua los yog tsawg tib yam. Ob hom muaj hluav taws xob thaiv hluav taws xob khiav los ntawm lawv thiab raug them nrog rwb thaiv tsev. Tab sis muaj qee qhov sib txawv.
Tus neeg hais lus hlau feem ntau yog nyias dua li cov xaim hluav taws xob thiab muaj cov rwb thaiv tsev zoo dua los yog ntau dua.
Hauv luv luv, cov neeg hais lus thiab cov xov hluav taws xob tsis tu ncua yog qhov tseem ceeb tib yam, yog li ob leeg tuaj yeem nqa hluav taws xob.
Tam sim no, voltage thiab lub zog
Thaum koj tuaj yeem siv tus hais lus xaim los muab lub zog, muaj qee yam kev txiav txim siab:
Tam sim no
Lub thickness ntawm cov hlau yuav txiav txim siab npaum li cas tam sim no nws tuaj yeem ua tau.
Raws li txoj cai dav dav, qhov tuab ntawm cov hlau, qhov ntau tam sim no tuaj yeem ntws los ntawm nws, thiab rov ua dua. Yog hais tias cov hlau loj tso cai rau tam sim no ntws los ntawm nws yam tsis tau ua rau nws overheat thiab ignite, koj tuaj yeem siv cov hlau uas ua hluav taws xob.
voltage
Cov kab lus hais lus tsuas yog tsim nyog rau kev ua haujlwm nrog qhov voltages txog 12 V, tab sis qhov no kuj nyob ntawm nws qhov tuab.
| Ceev faj | Nws yuav zoo dua yog tias koj tsis siv tus hais lus xaim rau kev sib txuas tseem ceeb (120/240V). Hais lus hlau feem ntau yog nyias dhau rau lub hom phiaj no. Yog tias koj siv sijhawm, tus hais lus hlau yuav yooj yim overheat thiab hlawv, uas tuaj yeem ua rau hluav taws. |
Cov xov hlau zoo tshaj plaws siv rau ntau tshaj li cov neeg hais lus yog cov xov hlau nrog tooj liab hauv. Qhov no yog vim lawv tsis tshua muaj zog thiab zoo hluav taws xob conductivity.
Lub zog (lub zog)
Cov qauv txiav txim siab lub zog lossis lub zog uas tus neeg hais lus tuaj yeem ua tau:
Yog li, lub zog uas tus hais lus xaim tuaj yeem nqa tau nyob ntawm qhov tam sim no thiab qhov hluav taws xob. Kuv tau hais los saum toj no tias tam sim no siab dua (thiab yog li ntawd lub zog ntawm tib qhov hluav taws xob) yuav tsum tau tuab dua / me dua hlau ntsuas. Yog li, lub ntsuas hluav taws xob me me (uas yuav tuab dua) tsis tshua muaj cua sov thiab yog li siv tau rau hluav taws xob ntau dua.
Lub hwj chim loj npaum li cas tuaj yeem siv tau rau tus hais lus?
Peb yuav tau ua qee qhov kev suav kom paub meej npaum li cas tus neeg hais lus xaim hluav taws xob peb tuaj yeem siv tau.
Qhov no yog ib qho tseem ceeb yog tias koj xav siv cov xov hlau hais lus los khiav cov khoom siv hluav taws xob kom tsis txhob muaj kev pheej hmoo ntawm cov hluav taws xob siab thiab cua sov. Ua ntej, cia peb pom ntau npaum li cas cov xov hlau tam sim no ntawm ntau qhov sib txawv tuaj yeem tiv taus.
| kab ntsuas | 16 | 14 | 12 | 10 | 8 | 6 |
| amperage | 13 | 15 | 20 | 30 | 40 | 50 |
Raws li koj tau pom, ib tug raug 15 amp Circuit Court siv rau lub teeb pom kev zoo yuav tsum muaj tsawg kawg yog 14 gauge hlau. Siv cov mis saum toj no (wattage = tam sim no x voltage), peb yuav txiav txim siab npaum li cas hwj chim ib tug hais lus hlau yuav tuav mus txog rau 12 amps ntawm tam sim no.. Kuv teev 12 amps (tsis yog 15) vim hais tias ib txwm peb yuav tsum siv tsis pub tshaj 80% ntawm cov hlau amperage.
Kev suav qhia tau hais tias rau 12 volts thiab 12 amps, cov xaim tuaj yeem siv rau lub zog mus txog 144 watts yog tias cov hlau muaj qhov ntsuas tsawg kawg yog 14.
Yog li ntawd, txhawm rau saib seb tus neeg hais lus xov tooj puas tuaj yeem siv rau ib qho tshwj xeeb 12 volt ntaus ntawv lossis khoom siv, xyuas nws qhov ntsuas hluav taws xob. Ntev npaum li 14-gauge hlau thiab lub ntsuas ntsuas tsis pub ntau tshaj 144 watts, nws muaj kev nyab xeeb siv.
Rau hom khoom siv twg tuaj yeem siv cov lus hais xov hlau?
Los ntawm kev nyeem txog qhov no, koj twb paub lawm tias hom khoom siv uas koj tuaj yeem siv cov lus hais xov tooj rau feem ntau yog qhov tsis tshua muaj hluav taws xob.
Thaum kuv them rau lwm yam tseem ceeb (tam sim no thiab wattage), kuv tau qhia, ua piv txwv, tias rau qhov siab tshaj plaws ntawm 12 amps, siv 14 gauge hlau thiab xyuas kom cov cuab yeej ntsuas tsis pub tshaj 144 watts. Nrog rau qhov no hauv siab, feem ntau koj tuaj yeem siv cov lus hais rau cov khoom siv thiab cov khoom siv hauv qab no:
- tswb lub qhov rooj
- Chaw nres tsheb qhov rooj qhib
- Tsev ruaj ntseg sensor
- toj roob hauv pes teeb pom kev zoo
- Tsawg voltage / LED teeb pom kev zoo
- Ntsuas Sov Thiab Txias
Vim li cas siv lub xov hlau acoustic los pib lub cuab yeej?
Tam sim no kuv yuav saib yog vim li cas koj yuav tsum siv lub xov tooj hais lus txawm tias txuas lub cuab yeej lossis khoom siv uas tsis yog tus hais lus.
Hauv lwm lo lus, cia peb saib nws qhov zoo thiab qhov tsis zoo. Tshooj lus no xav tias koj paub txog qhov voltage, tam sim no, thiab lub zog txwv tau piav qhia.
Cov txiaj ntsig ntawm kev siv cov kab lus hais lus
Loudspeaker xov hlau feem ntau yog nyias dua li cov kab hluav taws xob sib xws, kuj pheej yig dua thiab hloov tau yooj yim dua.
Yog li yog tias tus nqi yog qhov teeb meem, lossis koj xav tau kev hloov pauv ntau dua thaum xa xov ntawm cov khoom thiab lwm yam kev cuam tshuam, koj tuaj yeem siv cov lus hais.
Tsis tas li ntawd, piv rau cov kab hluav taws xob zoo sib xws, cov kab lus hais lus feem ntau tsis yooj yim dua thiab yog li tsis tshua muaj kev puas tsuaj.
Lwm qhov txiaj ntsig, txij li cov lus hais xov hlau feem ntau yog siv rau cov khoom siv hluav taws xob tsawg / tam sim no, yog tias nws tuaj yeem xav kom muaj kev nyab xeeb dua. Hauv lwm lo lus, qhov kev pheej hmoo ntawm kev raug hluav taws xob poob qis dua. Txawm li cas los xij, koj tseem yuav tau ceev faj nrog cov neeg hais lus nyob.
Disadvantages ntawm kev siv tus hais lus hlau
Qhov tsis zoo ntawm kev siv acoustic xaim yog tias nws muaj kev txwv ntau dua li cov khoom siv hluav taws xob zoo ib yam.
Cov xaim hluav taws xob tau tsim los txhawb cov hluav taws xob ntau dua thiab cov khoom siv tam sim no los muab lub zog ntau dua, thaum hais lus xov hlau tau tsim tshwj xeeb los nqa cov suab paj nruag. Cov kab lus hais tsis tuaj yeem siv rau cov hluav taws xob siab thiab cov khoom siv tam sim no. Raws li tau hais ua ntej, koj yuav raug hlawv cov hlau thiab pib hluav taws yog tias koj ua qhov no.
Koj yuav tsis tuaj yeem siv cov kab lus hais lus rau cov khoom siv hnyav. Yog tias koj npaj yuav siv cov xov hlau hais lus rau cov khoom siv thiab cov khoom siv uas yuav tsum tau siv cov khoom siv hluav taws xob, tsis nco qab txog nws.
Nrog cov hais lus xov hlau, koj raug txwv rau cov khoom siv hluav taws xob qis thiab qis tam sim no thiab cov ntawv thov uas yuav tsum tsis pub ntau tshaj 144 watts.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Yuav ua li cas txuas tus hais lus xaim mus rau phab ntsa phaj
- Qhov luaj li cas hais lus hlau rau lub subwoofer
