Ndi zinthu ziti zabwino zomwe mungagwiritse ntchito popanga subwoofer?

Mukamapanga subwoofer yanu komanso mawu ake apamwamba komanso okweza, muyenera kuganizira zamitundu yambiri yofunika. Mwachitsanzo, ndi wokamba uti amene mudagula kwa subwoofer, bokosi lanu ndi lolondola bwanji, pali mphamvu yokwanira ya amplifier, pali mphamvu yokwanira ya amplifier, etc.

M'nkhaniyi, tikhudza limodzi mwa mafunso ambiri omwe angakuthandizeni kuti mukhale pafupi ndi mabasi omveka komanso abwino. Momwemo, tiyankha funsoli, kuchokera kuzinthu ziti zomwe zili bwino kupanga bokosi la subwoofer?

Chifukwa chiyani subwoofer samasewera popanda bokosi?

Ngati tichotsa okamba m'bokosi la subwoofer yogwira ntchito, tidzapeza kuti mabasi omwe adapangidwanso ndi apamwamba amatha. Ndiko kuti, subwoofer yopanda bokosi (mapangidwe acoustic) samasewera! N’chifukwa chiyani zimenezi zikuchitika? Subwoofer imapanga kugwedezeka kwa mawu kumbali zonse ziwiri, mwachitsanzo, kutsogolo ndi kumbuyo. Ngati palibe chophimba pakati pa mbali izi, kugwedezeka kwa mawu kumathetsa. Koma ngati tiyika oyankhula a subwoofer mu bokosi lotsekedwa, tikhoza kulekanitsa kutsogolo ndi kumbuyo kwa subwoofer ndikupeza phokoso lapamwamba. Mwa njira, mu inverter gawo, bokosi limagwira ntchito pa mfundo yosiyana pang'ono, limatulutsa phokoso kumbali imodzi, zomwe zimawonjezera voliyumu poyerekeza ndi Z / Z pafupifupi 2 nthawi.

Momwe mabokosi a subwoofer amagwirira ntchito

Mukuti, chifukwa chiyani timafunikira izi zokhala ndi ma frequency, mafunde ndi mabokosi? Yankho ndi losavuta, tikufuna kukuwonetsani momveka bwino komanso mophweka momwe zinthu zomwe bokosi limapangidwira zimakhudzira ubwino wa zotsatira zomaliza.

Chimachitika ndi chiyani ngati bokosilo lapangidwa ndi zinthu zosafunikira

Tsopano tiyeni tiyerekeze kuti munapanga bokosi kuchokera ku zovala za agogo anu, ndiko kuti, munagwiritsa ntchito chipboard, yomwe ndi 15 mm yokha. Pambuyo pake, subwoofer yapakati-mphamvu idapangidwa kuchokera pamenepo. Kodi zotsatira zake zidzakhala zotani?

Chifukwa cha makulidwe osakwanira a khoma, kulimba kwa bokosi kumachepetsedwa. Phokoso likaimbidwa, makoma a bokosilo amayamba kunjenjemera, ndiko kuti, bokosi lonselo limasanduka radiator, mafunde a mawu amene bokosilo limatulutsa, ndiyeno amatsitsa mafunde amene wokamba nkhaniyo amatulutsa kutsogolo.

Kumbukirani, tinanena kuti wokamba subwoofer wopanda bokosi sangathe kutulutsa mabass. Chifukwa chake bokosi lolimba lotsika lidzapanga zotchinga pang'ono zokha, zomwe sizingathe kusunga kwathunthu kulowetsedwa kwa mafunde amawu otulutsidwa ndi okamba subwoofer. Zotsatira zake, mlingo wa mphamvu zotulutsa mphamvu umachepetsedwa ndipo phokoso limasokonezedwa.

Zomwe ziyenera kukhala bokosi la subwoofer

Yankho lake ndi losavuta. Chofunikira chachikulu chomwe bokosi la subwoofer liyenera kukwaniritsa ndi kukhazikika kwake ndi mphamvu zake. Kulimba kwa makoma, kumachepetsa kugwedezeka komwe subwoofer imapanga panthawi yogwira ntchito. Zoonadi, mwachidziwitso, bokosi lopangidwa ndi mbale ya ceramic kapena kuponyedwa kuchokera ku lead ndi makoma a masentimita 15 likhoza kuonedwa kuti ndiloyenera, koma ndithudi, izi zikhoza kuonedwa ngati zopanda pake, chifukwa ma subwoofers oterowo sadzakhala ndi mtengo wotsika mtengo, komanso kulemera kwakukulu.

Mitundu ndi kufananiza kwa zida za subwoofer.

Ganizirani zosankha zenizeni za zipangizo zopangira subwoofer ndikuyesera kupereka lingaliro laling'ono pa aliyense wa iwo.

Plywood

Bwino chinyezi kugonjetsedwa. M'malingaliro athu, ichi ndi chimodzi mwazinthu zoyenera kwambiri popanga zida zamayimbidwe.

Koma palinso zovuta zingapo;

• Izi ndizokwera mtengo kwambiri.
• Ndizovuta kupeza plywood yokhala ndi makulidwe opitilira 18 mm.
• Ndi gawo lalikulu la makoma, imayamba "kuyimba" (zowonjezera zolimba kapena ma spacers ndizofunikira)

MDF

Tsopano kupeza kutchuka kwakukulu. Ndi mtundu wa kusiyana pakati pa plywood ndi chipboard. Kuphatikizika kwake kwakukulu ndi mtengo wotsika kuposa plywood (pafupifupi chipboard), kukhazikika bwino (koma osati plywood). Zosavuta kuwona. Kukana kwa chinyezi ndikwapamwamba kuposa kwa chipboard.

• Ndizovuta, koma ndizotheka kupeza makulidwe opitilira 18 mm.

Chipboard

Zotsika mtengo, wamba. Pali mu kampani iliyonse ya mipando, m'makampani omwewo mungathe kuyitanitsa macheka. Bokosi ili lidzakutengerani 2-3 nthawi zotsika mtengo kuposa plywood. Zolakwika:

• Kukhazikika pang'ono kwazinthu (chitsanzo cha chipinda cha agogo pamwambapa).
• Osagonjetsedwa ndi chinyezi. Imayamwa chinyezi bwino ndikuphwanyika. Ndikowopsa makamaka ngati madzi alowa mu thunthu lanu.

Kodi mungawonjezere bwanji kulimba kwa bokosi?

1. Choyamba, chosavuta komanso chodziwika bwino. Uwu ndiwo makulidwe a zinthu, kukhuthala kwa zinthu, kumakulirakulira. Tikukulangizani kuti mugwiritse ntchito zida zosachepera 18 mm popanga subwoofer, ichi ndiye tanthauzo lagolide. Ngati subwoofer yanu ili ndi mphamvu yopitilira 1500w RMS, ndiye kuti sizingakhale zovuta kusankha makulidwe azinthu 20 mm kapena kupitilira apo. Ngati mukuvutika kupeza zida zokhuthala, mutha kugwiritsa ntchito malangizo awa.
2. Njira yomwe ingawonjezere kukhazikika ku bokosi lanu ndikupanga khoma lakutsogolo lapawiri. Ndiko kuti, gawo lakutsogolo lomwe wokamba nkhani amayikidwa. Gawo ili la subwoofer limawonekera kwambiri kupsinjika panthawi yogwira ntchito. Choncho, kukhala ndi zinthu m'lifupi 18 mm, kupanga kutsogolo khoma pawiri, timapeza 36 mm. Sitepe iyi idzawonjezera kwambiri kukhazikika kwa bokosi. Muyeneranso kuchita izi pokhapokha ngati subwoofer yanu ili ndi RMS (yovotera mphamvu) yoposa 1500w. Ngati muli ndi subwoofer ya mphamvu zochepa, mwachitsanzo, 700w, khoma lakutsogolo likhoza kupangidwanso kawiri. Pali lingaliro mu izi, ngakhale zotsatira zake sizidzakhala zazikulu kwambiri.
3. nsonga ina, gwiritsani ntchito ma spacers mkati mwa subwoofer kuti muwonjezere kulimba. Izi zimagwira ntchito makamaka ngati subwoofer ili ndi voliyumu yayikulu. Tiyerekeze kuti muli ndi ma subwoofers awiri a 12-inch (zokamba) m'bokosi lanu. Pakati, kukhwima kwa bokosi kudzakhala kochepa kwambiri chifukwa cha dera lalikulu. Pankhaniyi, sikudzakupwetekani kulimbikitsa kapangidwe kake ndikuyika spacer pamalo ano.

Ndizo zonse zomwe timafuna kukuuzani za subwoofer. Ngati nkhaniyi yakuthandizani, iwerengeni pamlingo wa mfundo zisanu pansipa.

Kodi mukufuna kuyesa kuwerengera nokha bokosi? Kuti tichite izi, nkhani yathu "Kuphunzira kuwerengera bokosi la subwoofer" idzakuthandizani.

Pomaliza

Tachita khama kwambiri popanga nkhaniyi, kuyesera kuilemba m'chinenero chosavuta komanso chomveka. Koma zili ndi inu kusankha ngati tinachita kapena ayi. Ngati mudakali ndi mafunso, pangani mutu pa "Forum", ife ndi gulu lathu laubwenzi tidzakambirana mwatsatanetsatane ndikupeza yankho labwino kwambiri.
