Ungayihlola kanjani i-subwoofer nge-multimeter

I-subwoofer esebenzayo ingenye yezinto ezibalulekile zesistimu yomsindo ephelele, noma ngabe ukusetha kwakho kungokwamamuvi, umculo, imidlalo, noma konke okungenhla.

Abantu ngokuvamile babheka ukuthuthukisa amasistimu abo omculo ngama-subwoofers ukuze bathuthukise amaza aphansi izipikha ezivamile ezingakwazi ukuphinda zikhiqize.

Inkinga nge-subwoofer ingaba nomthelela omubi kwikhwalithi yomsindo. Esimweni esinjalo, inketho engcono kakhulu ukuhlola i-subwoofer nge-multimeter.

Lo mhlahlandlela uzokusiza ukuthi ufunde ukuthi ungayihlola kanjani i-subwoofer nge-multimeter ngezinyathelo ezimbalwa nje ezilula.

Masingene kahle!

Isebenza kanjani i-subwoofer?

I-subwoofer iyingxenye ebalulekile yanoma iyiphi isistimu yomsindo ngoba iyisipikha esiklanyelwe ngokukhethekile ukukhiqiza kabusha umsindo wefrikhwensi ephansi. Ngenkathi ama-subwoofers amaningi esebenza, amanye awasebenzi futhi adinga ukuxhunywa ku-amplifier ukuze asebenze.

Ama-Subwoofers athumela amaza omsindo kuma-woofers ohlelweni lomculo, okuholela ekutheni kuzwakale amaza aphansi. Ama-subwoofers ngokuvamile afaneleka kakhulu kumasistimu omsindo wemoto noma amatiyetha asekhaya. Akuwona wonke ama-subwoofers anama-amplifiers akhelwe ngaphakathi. Kungase kudingeke ukuthi usebenzise i-amplifier yangaphandle ukuze ezinye zalezi zisebenze.

Unganquma kanjani ukuthi i-subwoofer inephutha

Kunezibonakaliso eziningi ezibonisa ukuthi i-subwoofer yakho inephutha noma cha. Lezi zisukela ekuntulekeni kwe-bass nokuhlanekezela kuya kumisindo eklwebhayo ezwakalayo.

Ikhoni ye-subwoofer embi ingase inganyakazi nhlobo. Ingase futhi inyakaze kakhulu, okungase ibonise ukuthi yonakele noma ayikho esimweni esihle kakhulu.

Indlela engcono kakhulu yokuqinisekisa ukuthi i-subwoofer yakho isebenza kahle ukuyihlola nge-multimeter. I-multimeter ingakala i-impedance, ihlole ikhoyili eshaywayo, futhi ilinganise ukuqhubeka.

Ungayihlola kanjani i-subwoofer nge-multimeter

Xhuma i-multimeter iholela kumatheminali amahle kanye nenegethivu ekhoyili yezwi ye-subwoofer, ibeka inani le-ohm, ikakhulukazi kububanzi obungu-200 ohm. Kulungile, uma uthola ukufundwa phakathi kuka-1 no-4, uma kungekho ukumelana, i-subwoofer cishe ishile.

Sizodlula isinyathelo ngasinye kanye nazo zonke ezinye izinyathelo ezibalulekile ngokuningiliziwe.

1. Nqamula i-subwoofer emthonjeni wamandla

Okokuqala, kufanele uthathe izinto ezidingekayo futhi unqamule i-subwoofer emthonjeni wamandla. Le nqubo ingaba lula njengokukhipha i-subwoofer kusikhulisa-zwi sangaphandle noma ukususa i-subwoofer kubhethri lemoto, kuye ngokuthi i-subwoofer iyasebenza noma ayisebenzi.

2. Susa i-subwoofer endlini

Ungakwazi ukususa i-subwoofer ngokuphephile emotweni ngemva kokuba inqanyuliwe emthonjeni wamandla. Kodwa-ke, kuye ngomklamo we-subwoofer, kungase kudingeke ukuthi ususe ikhoni endlini ukuze ufike ku-spool yocingo.

3. Faka i-multimeter lead kutheminali yekhoyili yezwi.

Ngemuva kokuyikhipha endlini, ama-multimeter probes kufanele afakwe kutheminali yokufaka yekhoyili ye-subwoofer cone wire. Lezi zibomvu nezimnyama, ezihambisana nokuhola okubomvu nokumnyama ku-multimeter.

Xhuma i-multimeter iholela kutheminali ye-subwoofer yombala ohambisanayo. Qinisekisa ukuthi zifakwe ngokugcwele ngaphambi kokuvula i-multimeter.

4. Setha ukumelana kwe-multimeter kuma-ohms

Kufanele ulinganise i-impedance ye-subwoofer ukuze uhlole izinkinga. Kufanele uvule ukudayela kwe-multimeter ku-ohms ukuze ulinganise ukumelana. Vula amandla bese ushintsha isethingi yokudayela ngaphambili kwe-multimeter ibe ama-ohms. Ukufundwa kufanele kuvele ngokushesha kusibonisi sedijithali.

Ku-multimeter, isilungiselelo se-Ohm simelelwa uphawu lwe-Omega (Ohm), njengoba uzobona, futhi olunezigaba ezimbalwa (2 MOhm, 200 Ohm, 2 kOhm, 20 kOhm, kanye no-200 kOhm).

Kufanele uvule i-multimeter ibe umkhawulo ongu-200 ohm ngoba iwububanzi obuphakeme obuseduze obunikeza imiphumela enembe kakhulu. Beka imikhondo emihle nebi eduze komunye nomunye ukuze uhlole ukuthi i-multimeter isethwe ngendlela efanele.

Uma yonke into isethwe kahle, i-multimeter izokhala ngemodi eqhubekayo noma ibonise inani eliseduze kakhulu noziro noma uziro uma kusetshenziswa ukulungiselelwa kwe-Ohms. Qhubekela esinyathelweni esilandelayo uma uwathola.

5. Linganisa imiphumela

Kuye nge-subwoofer yakho, i-multimeter kufanele ibonise ukufunda phakathi kuka-1 no-4. Uma ingabonisi noma yikuphi ukumelana, i-subwoofer cishe ishisiwe, futhi uma i-multimeter ibonisa ukufundwa okuphansi, kufanele ilahlwe. Ukwengeza, ikhoyili yezwi ingasha uma umsebenzi ukhukhuleka kaningi.

Indlela Yokuhlola I-Subwoofer Nge-Multimeter

Hlola i-subwoofer ngaphandle kwe-amplifier

Izwi elikhiqizwa yi-subwoofer yakho liyindlela elula yokulihlola. Ukuba ne-amplifier yalokhu kusiza kakhulu ekutholeni ukuthi yini engalungile nge-subwoofer yakho. Nge-amplifier, ungezwa ukukhubazeka nokuhlanekezelwa kwe-subwoofer eshile. Kodwa-ke, ungahlola i-subwoofer yakho ngaphandle kwe-amplifier uma ufuna ukunemba kakhudlwana nangokucophelela, noma uma ungenayo.

Kukhona indlela ongayisebenzisa uma ufuna ukuhlola i-subwoofer yakho ngaphandle kokusebenzisa i-amplifier. Ukuze wenze lokhu uzodinga ibhethri engu-9V, isihloli noma i-multimeter kanye nocingo. Uzodinga intambo, isihloli noma i-multimeter kanye nebhethri engu-9V.

Xhuma i-subwoofer nebhethri ngokuthatha intambo bese uxhuma itheminali ephozithivu yekhoyili ekugcineni kwebhethri engu-9-volt. Kungaba ngcono uma wenza okufanayo emaphethelweni ahlukene.

Uma ibhethri selixhunywe ngendlela efanele, thola ukuthi i-woofer cone iyaphakama yini. Uma usuxhuma ibhethri, i-subwoofer yakho kufanele iqale ukuphakama uma isebenza kahle. Futhi kufanele yehle ngemva kokucisha amandla. Kufanele ucabange ukuthi i-sub isivele ishaywa uma inganyakazi.

Uma kunjalo, hlola ukuze ubone ukuthi i-subwoofer ishile kusetshenziswa i-tester noma i-multimeter. Ungakwenza lokhu usebenzisa indlela yangaphambilini yokunquma i-subwoofer impedance. I-subwoofer yakho ishaywa uma ukufundwa kungaphansi kuka-1 ohm noma ngaphezulu.

Lena indlela enhle yokunquma ukuthi i-subwoofer yakho idinga ukulungiswa ngoba yehlulekile noma uma kunezinye izinkinga.

Kungenzeka yini ukulungisa i-subwoofer eshile?

Kwezinye izimo, ungakwazi ukulungisa i-subwoofer eshile ngokwakho. Uma ikhoyili yezwi ibambekile, thola ithoshi noma into eyindilinga efanayo futhi uyisebenzise ukusunduza ikhoyili yezwi ibuyele endaweni. Bese ubheka ukuthi iyasebenza yini.

Ungavala ukukhala usebenzisa iglue yekhava yothuli lwesipika kanye nethawula lephepha. Sebenzisa i-glue ukuze uvale imbobo ithawula ngemva kokuyisebenzisa. Ithawula lephepha kufanele libe bushelelezi ukuze kube nesiqephu esingenamthungo.

Uma igwebu lakho elizungezile liphukile, ungalilungisa ngokususa isikhala kuhlaka futhi usike ingxenye eyonakele ku-subwoofer. Ngemuva kokukhipha insalela ngokuxubha utshwala, namathisela i-foam trim entsha. Beka i-foam trim entsha bese uvumela ingcina yome kancane. Faka i-gasket ekugcineni.

isiphetho

Ukuhlola ama-subwoofers nge-multimeter ngezinkinga ezinjengokuntuleka kwe-bass noma ukuhlanekezela kungenye yezinqubo zokuxilonga ezilula uma uyenza ngendlela efanele.

Qiniseka ukuthi usetha i-multimeter yakho ebangeni elifanele ukuze uthole imiphumela efanele.

Imibuzo evame ukubuzwa

Wazi kanjani ukuthi i-subwoofer yakho ishile?

Unganquma ukuthi i-subwoofer iyashiswa yini, uma kungekho msindo nhlobo, uma umculo uhlanekezelwe noma u-creaky, uma kukhona ukunyakaza ku-diffuser, uma kukhona ama-pops nama-crackle ezwini.

Yini ebangela ukuthi i-subwoofer iyeke ukusebenza?

Isizathu esivame kakhulu sokwehluleka kwe-subwoofer amandla amaningi kakhulu. I-amplifier inweba amandla e-subwoofer uma ikhiqiza amandla amaningi futhi idala ingcindezi engabekezeleleki.
