Subwoofer ya Galimoto: Maziko a Phwando la Kumvetsera ndi Buku Lothandizira Kuthetsa Mavuto
Mu dziko la mawu a m'galimoto, subwoofer ili ngati ngwazi yodzichepetsa koma yofunika kwambiri yakumbuyo. Ndi mawu ake akuya komanso omveka bwino, imayala maziko a nyimbo iliyonse, zomwe zimapangitsa kuti okwera azikhala ndi mawu omveka bwino komanso omveka bwino.
Ntchito yaikulu ya subwoofer ya galimoto
Subwoofer imayang'anira makamaka kubwereza mawu omwe ali mu 20Hz - 250Hz frequency range. Bande la ma frequency ili limanyamula kulemera ndi kupsinjika kwa nyimbo, kukhala chinsinsi chopanga gawo lathunthu la mawu. Limasintha magetsi kukhala mafunde amakaniko, zomwe zimapangitsa kuti diaphragm igwedezeke ndikupanga mawu kudzera mu kayendedwe ka mpweya, ndikuyika nyimbo ndi soul.
Kuchokera pamalingaliro a zomwe zimamveka, subwoofer yapamwamba kwambiri imatha kukulitsa kwambiri chilakolako ndi mphamvu ya nyimbo. Poyimba nyimbo zolimba monga rock kapena electronic, besi yamphamvu ingapangitse kuti kugunda kwa ng'oma "kukhale kolimba", mizere ya besi imadziwika bwino, ngati kuti noti iliyonse ingakhudze mtima mwachindunji, ndikupanga mlengalenga wopatsirana kwambiri. Pakukwera galimoto, imathanso kubisa bwino phokoso lotsika, monga phokoso la matayala ndi misewu, phokoso loyendetsa injini, ndi zina zotero, zomwe zimathandiza okwera kusangalala ndi nyimbo pamalo opanda phokoso.
Kuchokera pa mfundo ya mawu, okamba wamba amakhala ndi malire pa kukula ndi makhalidwe enieni ndipo amavutika kubwereza bwino mawu otsika pafupipafupi ndi mafunde ataliatali. Komabe, ma subwoofers, okhala ndi ma diaphragms akuluakulu, m'mphepete mwake mofewa, ndi ma magnetic circuits amphamvu, kuphatikiza ndi zitseko za galimoto kapena malo obisika, amatha kupanga kusinthasintha kwa mphamvu mumlengalenga. Khutu la munthu limamva kwambiri ma frequency a 80 - 120Hz, zomwe zimapangitsa kulemera kwa ma drumbo ndi kutsimikizika kwa bass, popanda izo, nyimbo zingakhale ngati nyumba yopanda maziko, ngakhale treble yomveka bwino kwambiri imawoneka yopyapyala komanso yopyapyala.
Zolakwika zomwe zimachitika pa subwoofers zamagalimoto ndi njira zothetsera mavuto
Ngakhale kuti subwoofer imagwira ntchito yofunika kwambiri, ingakumanenso ndi zolakwika zosiyanasiyana panthawi yogwiritsa ntchito. Chofala kwambiri ndichakuti subwoofer imalephera kugwira ntchito. Zifukwa zake zimasiyana, ndipo mwiniwake amatha kupeza chomwe chimayambitsa vutoli mwa kuthetsa mavuto pang'onopang'ono.
Vuto lalikulu lomwe limayambitsa vutoli ndi vuto la mawaya. Mawaya a subwoofer akhoza kukhala ndi dera losweka, dera lalifupi, kapena kukhudzana kosayenera, monga mawaya akale kapena owonongeka, kapena mapulagi otayirira. Mwiniwake akhoza kuyang'ana mawaya omwe ali pa subwoofer kuti aone ngati pali zizindikiro zoonekeratu za kuwonongeka pa mawaya komanso ngati pulagiyo ndi yotetezeka. Ngati vuto la mawaya lapezeka, likhoza kukonzedwa kapena kusinthidwa ngati pakufunika kutero.
Subwoofer yokha imathanso kuwonongeka, zomwe zimapangitsa kuti isapange mawu. Kugwiritsa ntchito kwa nthawi yayitali kapena kukhudzidwa kwakunja kungayambitse kuti choyimbira cha mawu chizime, diaphragm isweke, ndi zina zotero. Mwiniwake akhoza kuyeza kukana kwa subwoofer ndi multimeter. Ngati kukana kuli kosazolowereka kapena subwoofer sikugwira ntchito ikalumikizidwa ku zida zina zachizolowezi zamawu, zitha kudziwika kuti subwoofer yawonongeka ndipo ikufunika kusinthidwa ndi yatsopano. Mukasankha subwoofer yatsopano, samalani ndi magawo ake ndi khalidwe lake kuti muwonetsetse kuti ikugwirizana ndi makina amawu agalimoto.
Zolakwika mu amplifier yamagetsi zingakhudzenso ntchito yanthawi zonse ya subwoofer. Ngati amplifier yamagetsi yalephera, singathe kupereka mphamvu yokwanira ku subwoofer, ndipo subwoofer sidzatha kutulutsa mawu. Izi zimafuna akatswiri okonza mawu kuti azitha kuzindikira ndi kukonza. Eni ake sayenera kuyesa kuichotsa okha, chifukwa ingayambitse kuwonongeka kwakukulu.
Kuphatikiza apo, makonda olakwika a mawu ndi ma fuse ophulika angayambitsenso kuti subwoofer isagwire ntchito. Mwiniwake angayang'ane kaye menyu ya makonda a audio system ya galimotoyo kuti atsimikizire ngati voliyumu ya subwoofer yazimitsidwa kapena yatsika kwambiri； kenako pezani fuse yogwirizana ndi audio system ndikuwona ngati ili bwino. Ngati yaphulika, isintheni ndi fuse ya specification yomweyo.
Mfundo zazikulu pakukhazikitsa ndi kukonza ma subwoofers agalimoto
Kuti subwoofer igwire bwino ntchito, magawo okhazikitsa ndi kukonza ndi ofunikira kwambiri. Pakukhazikitsa, samalani kuti mpweya usayende bwino pakati pa mabowo akutsogolo ndi akumbuyo, chifukwa izi zipangitsa kuti mphamvu ya ma frequency otsika itayike ndipo phokoso likhale lochepa komanso lochepa. Kugwiritsa ntchito zinthu za EVA poyika ma sealing pads kungathandize kuthetsa vutoli. Ndi lotanuka ndipo lili ndi mphamvu zothandizira, zomwe zimatha kukulunga bwino m'mphepete mwa sipika ndikudzaza mipata, zomwe zimapangitsa kuti bass ikhale yolimba komanso yolemera.
Mukamagwiritsa ntchito tsiku ndi tsiku, pewani kusewera nyimbo mokweza kwambiri kwa nthawi yayitali kuti mupewe kukalamba ndi kuwonongeka kwa sipika. Nthawi yomweyo, yang'anani nthawi zonse mawaya a sipika ndi mapulagi kuti muwonetsetse kuti kulumikizana kuli kotetezeka. Ngati galimotoyo ikudutsa m'malo odzaza madzi kapena ikuyendetsedwa pamalo onyowa kwa nthawi yayitali, yang'anani mwachangu ngati sipikayo ndi yonyowa. Ngati pakufunika kutero, chitani chithandizo chowumitsa.
Subwoofer yagalimoto ndi gawo lofunika kwambiri pamakina amawu agalimoto. Sikuti imangowonjezera mtundu wa nyimbo komanso imabweretsa chidziwitso chosangalatsa cha makutu kwa oyendetsa ndi okwera. Kumvetsetsa ntchito yake, kudziwa njira zothetsera mavuto a zolakwika zofala, komanso kuchita bwino pakukhazikitsa ndi kukonza kungatsimikizire kuti subwoofer imakhalabe bwino nthawi zonse, ndikuwonjezera nyimbo zabwino paulendo uliwonse.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
