Iyiphi impahla engcono kakhulu ongayisebenzisela i-subwoofer?

Lapho udala i-subwoofer yakho kanye nomsindo wayo wekhwalithi ephezulu nephezulu, kufanele ucabangele inani elikhulu lama-nuances abalulekile. Isibonelo, isiphi isipikha osithengele i-subwoofer, lilungile kangakanani ibhokisi lakho, ingabe kukhona amandla e-amplifier anele, ingabe akhona amandla anele we-amplifier, njll.

Kulesi sihloko, sizothinta omunye wemibuzo eminingi ezokusiza ukuthi usondele kuma-bass anomsindo futhi angcono. Okungukuthi, sizophendula umbuzo, kusuka kuyiphi impahla engcono kakhulu yokwenza ibhokisi le-subwoofer?

Kungani i-subwoofer ingadlali ngaphandle kwebhokisi?

Uma sisusa izipikha ebhokisini le-subwoofer esebenzayo, sizothola ukuthi i-bass ekhiqize kabusha ngekhwalithi ephezulu izonyamalala. Okusho ukuthi, i-subwoofer ngaphandle kwebhokisi (i-acoustic design) ayidlali! Kungani lokhu kwenzeka? I-subwoofer idala ukudlidliza komsindo kuzo zombili izinkomba, okungukuthi ukuya phambili nangemuva. Uma singekho isikrini phakathi kwalezi zinhlangothi, ukudlidliza komsindo kukhansela ngaphandle. Kodwa uma sifaka izipikha ze-subwoofer ebhokisini elivaliwe, singakwazi ukuhlukanisa ngaphambili nangemuva kwe-subwoofer futhi sithole umsindo wekhwalithi ephezulu. Ngendlela, ku-inverter yesigaba, ibhokisi lisebenza ngesimiso esihluke kancane, likhiqiza umsindo ohlangothini olulodwa, okwandisa ivolumu uma kuqhathaniswa ne-Z / Z cishe izikhathi ezi-2.

Asebenza kanjani amabhokisi e-subwoofer

Uthi, kungani sidinga lezi zinhlebo ezinamaza, amagagasi namabhokisi? Impendulo ilula, sifuna ukukubonisa ngokucacile nangokulula ukuthi indaba eyenziwe ngayo ibhokisi ithinta kanjani ikhwalithi yomphumela wokugcina.

Kwenzekani uma ibhokisi lenziwe ngezinto ezisezingeni eliphansi

Manje ake sicabange ukuthi wenze ibhokisi ekhabetheni likagogo wakho, okungukuthi, usebenzise impahla ye-chipboard, enobukhulu obuyi-15 mm kuphela. Ngemuva kwalokho, kwenziwa i-subwoofer yamandla aphakathi nendawo. Uyoba yini umphumela?

Ngenxa yokunganele kodonga, ukuqina kwebhokisi kulinganiswa kancane. Lapho umsindo udlalwa, izindonga zebhokisi ziqala ukuvevezela, okungukuthi lonke ibhokisi liphenduka libe irediyetha, amaza omsindo ibhokisi elizwakalayo, aphinde adambise amaza akhishwa isipika ohlangothini olungaphambili.

Khumbula, sithe isipikha se-subwoofer esingenabhokisi asikwazi ukukhiqiza kabusha ama-bass. Ngakho ibhokisi eliqinile eliphansi lizodala ukuvikela okuyingxenye kuphela, okungeke kukwazi ukugcina ngokuphelele ukungena kwamagagasi omsindo akhishwa yizipikha ze-subwoofer. Ngenxa yalokho, izinga lamandla okukhiphayo liyancishiswa futhi umsindo uhlanekezelwe.

Okufanele kube yibhokisi le-subwoofer

Impendulo ilula. Imfuneko eyinhloko okufanele ibhokisi le-subwoofer lihlangabezane nayo ukuqina kwayo namandla. Ukuqina kwezindonga, ukudlidliza okuncane okudala i-subwoofer ngesikhathi sokusebenza. Yiqiniso, ngombono, ibhokisi elenziwe ngepuleti ye-ceramic noma eliphonswe ngomthofu elinezindonga ezingu-15 cm lizobhekwa njengelifanele, kodwa-ke, lokhu kungabhekwa njengento engenangqondo, ngoba ama-subwoofers anjalo ngeke abe nokukhiqiza okubizayo kuphela, kodwa futhi nesisindo esikhulu.

Izinhlobo nokuqhathaniswa kwezinto ze-subwoofer.

Cabanga ngezinketho zangempela zezinto zokwakha i-subwoofer bese uzama ukunikeza isiphetho esincane kulowo nalowo wabo.

I-Plywood

Ukumelana nomswakama okungcono. Ngokombono wethu, lokhu kungenye yezinto ezifanele kakhulu zokwenziwa kwemishini ye-acoustic.

Kodwa kukhona futhi ezimbalwa downsides;

• Lena impahla ebiza kakhulu.
• Kuyinkinga ukuthola i-plywood enogqinsi olungaphezu kuka-18 mm.
• Ngendawo enkulu yezindonga, iqala "ukukhala" (iziqinisi ezengeziwe noma ama-spacers ayadingeka)

MDF

Manje ithola ukuthandwa okukhulu. Kuwuhlobo lwegebe phakathi kweplywood ne-chipboard. Ukuhlanganiswa kwayo okuyinhloko yinani eliphansi kuneplywood (cishe ifane ne-chipboard), ukuqina okuhle (kodwa hhayi kuze kufike ku-plywood). Kulula ukubona. Ukumelana nomswakama kuphakeme kunalokho kwe-chipboard.

• Kuyinkinga, kodwa kungenzeka ukuthola ukushuba okungaphezu kuka-18 mm.

Chipboard

Impahla eshibhile, evamile. Kukhona kuzo zonke izinkampani zefenisha, ezinkampanini ezifanayo ungakwazi uku-oda ukusika. Leli bhokisi lizokubiza izikhathi ezi-2-3 ezishibhile kuneplywood. Amaphutha:

• Ukuqina okuncane kakhulu kwezinto (isibonelo mayelana nekhabethe likagogo elingenhla).
• Ayimelani nomswakama. Imunca umswakama kahle bese iyabhidlika. Kuyingozi kakhulu uma amanzi engena esiqwini sakho.

Indlela yokwandisa ukuqina kwebhokisi?

1. Okokuqala, elula futhi esobala kakhulu. Lokhu ukushuba kwezinto, ukuqina kwempahla, ukuqina okukhulu. Sikweluleka ukuthi usebenzise izinto okungenani eziyi-18 mm ekwenzeni i-subwoofer, lena incazelo yegolide. Uma i-subwoofer yakho inamandla angaphezu kuka-1500w RMS, ngeke kube yinto engafanele ukukhetha ubukhulu bempahla obungu-20 mm noma ngaphezulu. Uma unenkinga yokuthola izinto ezinodonga oluwugqinsi, ungasebenzisa izincomo ezilandelayo.
2. Inketho ezongeza ukuqina ebhokisini lakho ukwenza udonga lwangaphambili oluphindwe kabili. Okusho ukuthi, ingxenye engaphambili lapho kufakwa khona isipika. Le ngxenye ye-subwoofer ibonakala kakhulu ekucindezelekeni phakathi nokusebenza kwayo. Ngakho-ke, ukuba nobubanzi bezinto ezingu-18 mm, okwenza udonga lwangaphambili lube kabili, sithola 36 mm. Lesi sinyathelo sizokwengeza ngokuphawulekayo ukuqina kwebhokisi. Kufanele futhi wenze lokhu uma nje i-subwoofer yakho ine-RMS (amandla alinganiselwe) angaphezu kuka-1500w. Uma une-subwoofer yamandla amancane, isibonelo, i-700w, udonga lwangaphambili lungenziwa futhi kabili. Kunomqondo kulokhu, nakuba umphumela walokhu ngeke ube mkhulu kakhulu.
3. Elinye ithiphu, sebenzisa izikhala ngaphakathi kwe-subwoofer ukuze ungeze ukuqina okwengeziwe. Lokhu kusebenza kahle ikakhulukazi uma i-subwoofer inevolumu enkulu. Ake sithi unama-subwoofers amabili angu-12-intshi (izipikha) ebhokisini lakho. Phakathi nendawo, ukuqina kwebhokisi kuzoba kuncane kakhulu ngenxa yendawo enkulu. Kulesi simo, ngeke kukulimaze ukuqinisa isakhiwo nokufaka i-spacer kule ndawo.

Yilokho kuphela ebesifuna ukukutshela mayelana nezinto ze-subwoofer. Uma lesi sihloko sikusize, yikale esikalini samaphuzu amahlanu ngezansi.
