Ukufunda ukubala ivolumu enetha kanye nembobo yebhokisi le-subwoofer yesigaba se-inverter
Okuqukethwe
Ngokuvamile, abathandi bomsindo omuhle wemoto banombuzo: indlela yokubala ibhokisi le-subwoofer ukuze lisebenze ngokubuya okuphezulu kakhulu? Ungasebenzisa izincomo ezivela kubakhiqizi be-subwoofer. Nokho, zingase zinganele ukufeza umphumela omuhle kakhulu.
Iqiniso liwukuthi abakhiqizi abacabangi indawo yokufaka yebhokisi, kanye nesitayela somculo odlalwayo. Ngesikhathi esifanayo, ikhwalithi yomsindo ingamukeleka impela. Kodwa noma kunjalo, kuzokwazi "ukugubha" i-subwoofer ngangokunokwenzeka kuphela ngokucabangela izici zomshini kanye nesitayela somculo odlalwayo. Ngakho-ke isidingo sokubala komuntu ngamunye kwebhokisi le-subwoofer ecaleni ngalinye elithile.
Kunezinhlelo eziningi ezikhethekile eziklanyelwe ukusiza ekuxazululeni le nkinga. Okudume kakhulu yi-JBL SpeakerShop. Nakuba i-JBL ikhiphe le software isikhathi eside kakhulu, isaqhubeka nokudingeka kakhulu phakathi kwalabo abenza awabo ama-subwoofers. Ngesikhathi esifanayo, bahlala bedlala kahle "ama-subs". Ukuze ukwazi konke ukusebenza kohlelo, oqalayo angase adinge isikhathi esithile. Naphezu kobukhulu bayo obuncane, iqukethe amagrafu amaningi, amasimu nezinye izilungiselelo okudingeka uziqonde ngokucophelela.
Yini okudingeka ukwazi ngaphambi kokufaka i-JBL SpeakerShop?
Lolu hlelo lokubala lwe-subwoofer lungafakwa kuphela kukhompuyutha ye-Windows. Ngeshwa, yakhululwa kudala, ngakho-ke ihambisana kuphela nezinguqulo ezisuka ku-XP nangaphansi. Ukufaka ezinguqulweni zakamuva zesistimu (Windows 7, 8, 10), uzodinga i-emulator ekhethekile ekuvumela ukuthi ulingise i-XP.
Phakathi kwezinhlelo ezaziwa kakhulu, futhi ngasikhathi sinye zamahhala ezikuvumela ukuthi ulingise izinguqulo zangaphambili zeWindows, faka i-Oracle Virtual Box. Kulula kakhulu futhi kuyaqondakala. Unalokhu kuphela engqondweni, futhi ngemva kokwenza ukukhohlisa kwasekuqaleni, ungafaka uhlelo lwe-JBL SpeakerShop.
Ukuze uthole ulwazi olwengeziwe, sikweluleka ukuthi ufunde isihloko esithi "Ibhokisi le-subwoofer" lapho izinhlobo ezimbili zamabhokisi zichazwe ngokuningiliziwe, nokuthi iyiphi ivolumu okufanele ikhethwe.
Ungasebenza kanjani nge-JBL SpeakerShop?
Konke ukusebenza kohlelo kuhlukaniswe ngamamojula amabili amakhulu. Usebenzisa eyokuqala, ungakwazi ukubala umthamo webhokisi le-subwoofer. Eyesibili isetshenziselwa ukubala i-crossover. Ukuze uqale ukubala, kufanele uvule i-SpeakerShop Enclosure Module. Inamandla okulingisa impendulo yemvamisa yamabhokisi avaliwe, i-bass-reflex enclosures, ama-bandpass, kanye nama-radiator asebenzayo. Empeleni, izinketho ezimbili zokuqala zivame ukusetshenziswa kakhulu. Ubuningi bezinkambu zokufaka bungadida. Nokho, ungalilahli ithemba.
Ukuze ubale ukufuduka, kwanele ukusebenzisa amapharamitha amathathu kuphela:
- imvamisa ye-resonant (Fs);
- umthamo olinganayo (Vas);
- isici sekhwalithi ephelele (Qts).
Ukuze uthuthukise ukunemba kwesibalo, kuvunyelwe ukusebenzisa ezinye izici. Lezi zingatholakala kumamanyuwali wezipikha noma ku-inthanethi. Kodwa-ke, njengoba kushiwo ngenhla, ungadlula ngokuphelele ngalezi zici ezintathu, ezibizwa ngokuthi amapharamitha we-Thiel-Smol. Ungafaka le mingcele ngendlela evelayo ngemva kokucindezela izinkinobho ze-Ctrl + Z. Ngaphezu kwalokho, ungaya efomini ngemuva kokukhetha into yemenyu Isikhulisazwi - Amapharamitha amancane. Ngemva kokufaka idatha, uhlelo luzokwazisa ukuthi uluqinisekise. Esigabeni esilandelayo, kuyadingeka ukulingisa isici se-amplitude-frequency, ke - impendulo yemvamisa.
Sibala inverter yezindlu zesigaba
Okokuqala, sizobonisa isibonelo sokubala inverter yezindlu zesigaba. Esigabeni seBhokisi Elikhipha umoya, khetha Ngokwezifiso. Ukucindezela inkinobho ye-Optimum kugcwalisa ngokuzenzakalelayo zonke izinkambu. Kodwa kulokhu, ukubala kuyoba kude kakhulu nokuhle. Ukuze uthole izilungiselelo ezinembayo, kungcono ukufaka idatha mathupha. Esigabeni se-Vb, udinga ukucacisa inani levolumu yebhokisi, futhi ku-Fb, isilungiselelo.
Ivolumu yebhokisi nokusetha
Kufanele kuqondwe ukuthi ukulungiselelwa kukhethwe ngokohlobo lomculo ozodlalwa kakhulu. Ngomculo onamaza aphansi aminyene, le parameter ikhethwa phakathi kwebanga elingu-30-35 Hz. Ilungele ukulalela i-hip-hop, i-R'n'B, njll. Kubathandi be-rock, i-trance kanye nomunye umculo we-high-frequency, le pharamitha kufanele isethwe kusukela ku-40 nangaphezulu. Kubathandi bomculo abalalela izinhlobo ezahlukene, inketho engcono kakhulu kungaba ukukhethwa kwamafrikhwensi amaphakathi.
Lapho ukhetha usayizi wevolumu, umuntu kufanele aqhubeke nobukhulu besipikha. Ngakho-ke, isipika esingu-12-intshi sidinga ibhokisi le-bass-reflex elinomthamo "ohlanzekile" ongaba amalitha angama-47-78. (bheka isihloko mayelana namabhokisi). Uhlelo lukuvumela ukuthi ufake ngokuphindaphindiwe izinhlanganisela ezahlukene zamanani, bese ucindezela okuthi Yamukela, bese u-Plot. Ngemva kwalezi zenzo, kuzovela amagrafu okuphendula imvamisa yesipika afakwe emabhokisini ahlukahlukene.
Ngokukhetha amanani evolumu nezilungiselelo, ungeza kwinhlanganisela oyifunayo. Inketho engcono kakhulu ijika lokuphendula imvamisa, elifana negquma elithambile. Ngesikhathi esifanayo, kufanele ikhuphukele ezingeni lika-6 dB. Akufanele kube khona ukukhuphuka nokwehla. Isiqongo segquma elicatshangwayo kufanele sibe endaweni yenani elikhonjiswe kunkambu ye-Fb (35-40 Hz, ngaphezu kuka-40 Hz, njll.).
Ungakhohlwa ukuthi lapho ubala i-subwoofer yemoto, kuyadingeka ukufaka umsebenzi wokudlulisa wegumbi labagibeli.
Kulesi simo, umuntu kufanele acabangele ukuphakama "kwezigaba eziphansi" ngenxa yomthamo wekhabhinethi. Unganika lesi sici amandla ngokumaka ibhokisi eliseduze nesithonjana semoto encane elitholakala ngenhla ekhoneni eliphezulu kwesokudla segrafu.
Port Volume Ukubala
Ngemva kokumodela ijika lokuphendula imvamisa, kusale kuphela ukubala imbobo. Lokhu kungenziwa ngento yemenyu ethi Box-Vent. Futhi, iwindi lingavuleka ngemuva kokucindezela u-Ctrl+V. Ukufaka idatha, khetha Ngokwezifiso. Ngembobo eyindilinga, khetha I-Diameter, kanye nembobo enembobo, khetha Indawo. Ake sithi ufuna ukubala indawo yembobo efakwe slot.
Kulokhu, udinga ukuphindaphinda umthamo webhokisi ngo-3-3,5 (cishe). Ngomthamo webhokisi "elihlanzekile" lamalitha angu-55, i-165 cm2 (55 * 3 = 165) itholakala. Le nombolo kufanele ifakwe kunkambu ehambisanayo, ngemva kwalokho ukubalwa okuzenzakalelayo kobude bembobo kuzokwenziwa.
Kulokhu, izibalo zibhekwa njengeqediwe! Kodwa-ke, kufanelekile ukukhumbula ukuthi uhlelo lubala kuphela ivolumu "inetha". Ungakwazi ukunquma isamba sevolumu ngokwengeza amavolumu wembobo nodonga lwayo kunani "elihlanzekile". Ukwengeza, udinga ukungeza ivolumu edingekayo ukuze kuhambisane nesipika.Emva kokunquma amanani adingekayo, ungaqala ukulungisa umdwebo. Ingavezwa ngisho nasephepheni elilula, ngisho nangezinhlelo zokumodela ze-3D. Lapho ukuklama kuwufanele
cabangela ubukhulu bodonga lwebhokisi. Abantu abanolwazi bayeluleka ukwenza izibalo ezinjalo nangaphambi kokuba isikhulumi sithengwe. Lokhu kuzokuvumela ukuthi wenze i-subwoofer engakwazi ukwanelisa zonke izicelo.
Mhlawumbe ibhokisi lakho likusizindalwazi sethu semidwebo eqediwe.
