Kodi subwoofer imagwira ntchito bwanji

Subwoofer ndi gawo lofunikira pamawu aliwonse amawu chifukwa ndi chowulira mawu chomwe chimapangidwira makamaka kutulutsa mawu ocheperako. Ngakhale ma subwoofers ambiri ali ndi mphamvu, ena amakhala opanda pake ndipo amafuna amplifier kuti agwire ntchito.

Ma subwoofers amatumiza mafunde omveka kwa ma subwoofers mumayendedwe a nyimbo, zomwe zimapangitsa kuti ma frequency amveke bwino. Ma subwoofers nthawi zambiri amakhala oyenererana ndi makina amawu amagalimoto kapena makina owonetsera kunyumba. Sikuti ma subwoofers onse ali ndi amplifiers omangidwira. Mungafunike kugwiritsa ntchito amplifier kunja kwa magwiridwe antchito a ena mwa iwo.

Momwe mungadziwire ngati subwoofer ili ndi vuto

Pali zizindikiro zambiri zomwe zimasonyeza ngati subwoofer yanu ili ndi vuto kapena ayi. Izi zimachokera ku kusowa kwa bass ndi kupotoza mpaka kumamvekedwe omveka bwino.

Cone ya subwoofer yoyipa ikhoza kusasuntha konse. Zitha kukhalanso zogwedezeka kwambiri, zomwe zingasonyeze kuti zawonongeka kapena sizinali bwino.

Njira yabwino yowonetsetsa kuti subwoofer yanu ikugwira ntchito bwino ndikuyesa ndi multimeter. Multimeter imatha kuyeza kulephera, kuyang'ana koyilo yowotchedwa, ndikuyesa kupitiliza.

Momwe mungayesere subwoofer ndi multimeter

Lumikizani ma multimeter amatsogolera kumayendedwe abwino ndi oyipa a coil a subwoofer, ndikuyiyika pamtengo wotsutsa mu ohms, makamaka mumitundu ya 200 ohm. Chabwino, ngati mupeza zowerengera kuchokera ku 1 mpaka 4, ngati palibe kukana, subwoofer mwina yatenthedwa.

Tidzadutsa mu sitepe iliyonse ndi sitepe ina iliyonse yofunika mwatsatanetsatane.

1. Lumikizani subwoofer kuchokera pamagetsi

Choyamba, muyenera kutenga zofunikira ndikuchotsa subwoofer kuchokera kugwero lamagetsi. Njirayi ikhoza kukhala yophweka ngati kuchotsa subwoofer kuchokera ku amplifier yakunja kapena kuchotsa subwoofer kuchokera ku batri ya galimoto, malingana ndi ngati subwoofer ikugwira ntchito kapena ikugwira ntchito.

2. Chotsani subwoofer pamlanduwo

Mukhoza kuchotsa bwinobwino subwoofer m'galimoto mutachotsedwa pamagetsi. Komabe, malingana ndi mapangidwe a subwoofer, mungafunike kuchotsa cone kuchokera ku kabati kuti mufike ku spool ya waya.

3. Lowetsani ma multimeter otsogolera mu koyilo ya mawu.

Mukachichotsa m'nyumba, ma probe a multimeter amayenera kulowetsedwa mu cholumikizira cha waya cha subwoofer diffuser. Izi ndi zofiira ndi zakuda, zogwirizana ndi zofiira ndi zakuda pa multimeter.

Lumikizani multimeter imatsogolera ku subwoofer terminal ya mtundu wofananira. Onetsetsani kuti alowetsedwa mokwanira musanayatse multimeter.

4. Khazikitsani kukana kwa multimeter mu ohms

Muyenera kuyeza kulephera kwa subwoofer kuti muwone zovuta. Muyenera kutembenuza kuyimba kwa ma multimeter kukhala ohm kuti muyese kukana. Yatsani mphamvu ndikusintha kuyimba kutsogolo kwa multimeter kukhala ohms. Chiwonetsero cha digito chiyenera kuwonetsa kuwerenga nthawi yomweyo.

Pa multimeter, ohm setting imasonyezedwa ndi chizindikiro Omega (Ohm), yomwe, monga momwe mukuonera, ilinso ndi mizere ingapo (2 MΩ, 200 Ω, 2 kΩ, 20 kΩ, ndi 200 kΩ).

Muyenera kutembenuza ma multimeter kukhala malire a 200 ohm chifukwa ndiwo malo apamwamba kwambiri omwe amapereka zotsatira zolondola kwambiri. Ikani njira zabwino ndi zoipa pafupi wina ndi mzake kuti muwone ngati multimeter yakhazikitsidwa molondola.

Ngati zonse zakhazikitsidwa bwino, multimeter idzalira mopitilira kapena kuwonetsa mtengo pafupi kwambiri ndi ziro kapena zero pamene ohm ikugwiritsidwa ntchito. Pitani ku sitepe yotsatira ngati mwalandira.

5. Voterani zotsatira

Malingana ndi subwoofer yanu, multimeter iyenera kuwerenga pakati pa 1 ndi 4. Ngati sichiwonetsa kutsutsa, subwoofer mwina imawotchedwa, ndipo ngati multimeter ikuwonetsa kuwerenga kochepa, iyenera kutayidwa. Komanso, phokoso la mawu likhoza kupsa ngati ntchitoyo ikugwedezeka nthawi zambiri.

Kanema Wotsogolera

Mutha kuwonanso kalozera wathu wamavidiyo:

Momwe Mungayesere Subwoofer Ndi Multimeter

Yesani subwoofer popanda amplifier

Mawu omwe subwoofer yanu ikusewera ndi njira yosavuta yoyesera. Kukhala ndi amplifier kwa izi ndikothandiza kwambiri kudziwa chomwe chili cholakwika ndi subwoofer yanu. Ndi amplifier, mutha kumva zolakwika ndi kupotoza kwa subwoofer yowotchedwa. Komabe, mutha kuyesa subwoofer yanu popanda amplifier ngati mukufuna kukhala olondola komanso omveka bwino, kapena mulibe.

Pali njira yomwe mungagwiritse ntchito ngati mukufuna kuyesa subwoofer popanda kugwiritsa ntchito amplifier. Kuti muchite izi, mufunika batire ya 9V, tester kapena multimeter, ndi waya. Mudzafunika waya, tester kapena multimeter ndi batire ya 9V.

Lumikizani subwoofer ndi batire potenga waya ndikulumikiza mapeto abwino a koyilo mpaka kumapeto kwa batire la 9 volt. Zingakhale bwino mutachita chimodzimodzi kumbali zosiyana.

Batire ikalumikizidwa bwino, dziwani ngati cone ya woofer ikukwera. Mukangolumikiza batire, subwoofer yanu iyenera kuyamba kuwuka ngati ikugwira ntchito bwino. Ndipo iyenera kuchepa mukatha kuzimitsa mphamvu. Muyenera kuganiza kuti subwoofer yawombedwa kale ngati sichisuntha.

Ngati ndi choncho, onani ngati subwoofer yawotchedwa ndi tester kapena multimeter. Mutha kuchita izi pogwiritsa ntchito njira yapitayi ya subwoofer impedance. Subwoofer yanu imawotchedwa ngati kuwerenga kuli 1 ohm kapena kupitilira apo.

Iyi ndi njira yabwino yodziwira ngati subwoofer yanu ikufunika kukonzedwa chifukwa yalephera kapena pali mavuto ena.

Kodi subwoofer yowotchedwa ingakonzedwe?

Nthawi zina, mutha kukonza subwoofer yowombedwa nokha. Ngati koyilo yanu ya mawu yakakamira, pezani tochi kapena chinthu chozungulira chofananira ndikuchigwiritsa ntchito kukankhira koyiloyo pamalo ake. Ndiye muwone ngati izo zikugwira ntchito.

Mutha kusindikiza kusiyana ndi zomatira fumbi lophimba zomatira ndi chopukutira chapepala. Gwiritsani ntchito guluu kuti mutseke dzenje mu chopukutira mukachipaka. Chopukutira chapepala chiyenera kukhala chosalala kuti chikhale chopanda msoko.

Ngati chithovu chanu chozungulira chasweka, mutha kuchikonza pochotsa spacer pa chimango ndikudula gawo lowonongeka kuchokera ku subwoofer. Pambuyo kuchotsa zotsalira ndi mowa, angagwirizanitse latsopano thovu edging. Ikani chithovu chatsopanocho ndikusiya guluu kuti liume pang'ono. Ikani gasket komaliza.

Pomaliza

Kuyang'ana ma subwoofers okhala ndi ma multimeter pamavuto monga kusowa kwa bass kapena kupotoza ndi njira imodzi yosavuta yodziwira ngati mukuchita bwino.

Onetsetsani kuti mwayika ma multimeter anu pamlingo woyenera kuti mupeze zotsatira zolondola.

Mafunso ofunsidwa kawirikawiri

Kodi mungadziwe bwanji ngati subwoofer yanu yatenthedwa?

Mungathe kudziwa ngati subwoofer yatenthedwa, ngati palibe phokoso, ngati nyimbo ikusokonekera kapena kugwedezeka, ngati pali kusuntha mu cone, ngati pali ma pops ndi phokoso m'mawu.

Nchiyani chimapangitsa subwoofer kusiya kugwira ntchito?

Chomwe chimayambitsa kulephera kwa subwoofer ndi mphamvu zambiri. Amplifier imapatsa mphamvu subwoofer ikatulutsa mphamvu zambiri ndikupanga kukakamiza kosatha.
