Wokamba nkhani wodalirika kwambiri pagalimoto: Ubwino wa mawu ndi chitsogozo chothetsera mavuto
Mu "ufumu wa mawu" wa makina a mawu agalimoto, sipika ya mafunde amphamvu mosakayika ndiye "wamatsenga watsatanetsatane". Mafunde amphamvu omwe makutu a anthu amatha kuzindikira ndi pakati pa 20Hz ndi 20kHz. Sipika ya mafunde amphamvu nthawi zambiri imakhala ndi vuto lobwerezabwereza molondola mawu ofooka omwe ali pamwamba pa 10kHz, koma sipika ya mafunde amphamvu imapangidwa mwapadera kuti ikwaniritse kusiyana kumeneku. Imadzipereka kubwezeretsa zizindikiro za mafunde amphamvu, ndi mafunde amphamvu omwe amaphimba 5KHz - 20KHz, ndipo imatha kuwonetsa bwino zida zoimbira, mphezi ya mawu a anthu, ndi kuwala kwa zida za zingwe, zomwe zimapangitsa kuti kumvetsera nyimbo kukhale kowonekera bwino komanso kokhala ndi magawo atatu. Popanda kutenga nawo mbali kwa sipika ya mafunde amphamvu, nyimbo zingakhale ngati thupi lopanda mzimu, lomveka losamveka bwino komanso losamveka bwino, ndipo nthawi zambiri limatha kutaya mphamvu yake yoyendetsa galimoto pa liwiro lalikulu.
Kuchokera pamalingaliro a kapangidwe kake, ma speaker a magalimoto odalirika kwambiri amakhala amtundu wa dome, ogawika m'magulu awiri: dome yabwino ndi dome yoyipa. Dome yabwino ili ndi ngodya yotakata yotambalala, zomwe zimathandiza kuti malo ambiri mkati mwa galimotoyo amve bwino tsatanetsatane wa ma frequency apamwamba; dome yoyipa ili ndi ngodya yaying'ono yopingasa koma ili ndi mawu oyera ndipo imatha kugwira mphamvu yayikulu^ Zinthu zomwe zili mu diaphragm zimakhudza mwachindunji mawonekedwe a mawu. Dome yolimba (aluminium alloy, titanium alloy, etc.) ili ndi resolution yamphamvu ndipo ndiyoyenera kuwonetsa mwamphamvu nyimbo za pop ndi zotsatira za mawu a kanema; dome yofewa (silicone film, silika film) ili ndi mawu ofewa ndipo ndi yoyenera bwino nyimbo zakale ndi mawu^
Malo oikira mawu ndi ofunikira kwambiri pakugwira ntchito kwa ma speaker amphamvu kwambiri. Kuti atsimikizire kuti malo olumikizira mawu ali pamlingo womwewo ndi khutu la munthu ndikupanga njira yolondola yotumizira mawu, nthawi zambiri amaikidwa pa A-pillar, pamwamba pa dashboard, kapena pakhomo la galimoto. Kapangidwe kameneka kamalola kuti tsatanetsatane wa ma frequency apamwamba utumizidwe mwachindunji ku khutu popanda kutayika kulikonse, zomwe zimapangitsa kuti mkati mwa galimotoyo muzioneka ngati holo yaying'ono ya konsati. Eni magalimoto ambiri amatha kusintha kwathunthu makina olumikizira mawu agalimoto pongowonjezera ma speaker amphamvu kwambiri a silika. Ma slits otsetsereka a vayolini amaonekera bwino, ndipo mpweya wa mawu a akazi umawonekera patsogolo pa makutu awo. Kumva kuzungulira ndi kumiza kumawonjezeka kwambiri.
Komabe, "wopereka mawu abwino" uyu angakumanenso ndi mavuto osagwira ntchito bwino, mavuto omwe amapezeka nthawi zambiri ndi monga kusamveka bwino, mawu osokonekera, phokoso lochepa kwambiri kapena phokoso lakumbuyo, ndi zina zotero. Kuti muthetse vutoli, gawo loyamba ndikupeza molondola chomwe chimayambitsa vutoli.
Ngati sipika yokweza mawu ili chete, mutha kuthetsa mavuto potsatira njira ya "mphamvu - kulumikizana - zoikamo - zida". Choyamba, onani ngati fuse ya dongosolo la mawu yaphulika, komanso ngati malo olumikizira magetsi ali otetezeka komanso opanda dzimbiri; kenako, yang'anani zingwe za RCA lily-head ndi mawaya a sipika kuti muwone ngati zamasuka kapena zasungunuka, ndikuwona ngati gawo lobowoka la waya wa sipika ya chitseko lasweka chifukwa cha kutsegula ndi kutseka mobwerezabwereza kwa chitseko; kenako, tsimikizirani ngati voliyumu ya wolandila mawu ndi zero, ngati switch yoyimitsa mawu ili yoyatsidwa, ndipo ngati njira yotulutsira mawu yayikidwa molakwika; pomaliza, gwiritsani ntchito multimeter kuti muyese kukana kwa sipika. Mtundu wabwinobwino uyenera kukhala 3.2 - 4.5 Ω. Ngati kuwerenga kukuwonetsa kusakhalapo kapena kuli pafupi ndi 0 Ω, zimasonyeza kuti gawo la sipika lawonongeka.
Ngati phokoso lasokonekera kapena pali phokoso, n'zotheka kuti cholankhuliracho chili ndi vuto. Kuwonongeka kwa diaphragm ndi chifukwa chofala. Diaphragm ya cholankhulira chapamwamba ndi yopyapyala ndipo imatha kusweka chifukwa cha kukhudzidwa kwakunja kapena kutentha kwambiri. Kuwonongeka pang'ono kumatha kukonzedwa ndi guluu waluso, koma kuwonongeka kwakukulu kumafuna kusintha diaphragm. Ndikofunikira kuti katswiri achite izi kuti atsimikizire kuti yayikidwa bwino. ^ Kutopa kapena kufupika kwa coil yamawu kungayambitsenso mawu osazolowereka. Kuyeza mtengo wotsutsa ndi multimeter kungathandize kudziwa izi. Kusintha coil yamawu kumafuna kulondola kwambiri, ndipo ndikulimbikitsidwanso kupita nayo ku shopu yokonza akatswiri. ^ Kuphatikiza apo, mawaya otayirira, kukhudzana kosayenera, kapena kusokoneza kungayambitsenso phokoso mu mawu apamwamba. Yang'anani mosamala mizere yolumikizira, yeretsani ma interfaces oxidized, ndikusintha mizere yowonongeka ngati pakufunika.
Palinso zolakwika zina zomwe zimachitika nthawi ndi nthawi. Izi nthawi zambiri zimagwirizana ndi kulumikizana kwa mizere. Mwachitsanzo, kukhudzana koyipa pamalo olumikizira mawaya, kusagwira bwino ntchito kwa mabatani a sipika, kapena mavuto ndi ma relay ndi ma control unit. Momwe mzere uliwonse umalumikizira komanso momwe umalumikizira ziyenera kugwiritsidwira ntchito ziyenera kufufuzidwa chimodzi ndi chimodzi. Nthawi zina, zigawo zofunikira ziyenera kusinthidwa.
Kukonza nthawi zonse kungathandize kuti sipika yokweza mawu ikhale ndi moyo wautali. Pewani kusewera ndi mawu ambiri kwa nthawi yayitali kuti sipika isachuluke kwambiri; mukatsuka mkati, musamapopere madzi pamakina amawu; gwiritsani ntchito thaulo louma kapena chopukutira chonyowa kuti mupukute fumbi, kenako tsegulani mawindo kuti chinyezi chisathe; yang'anani nthawi zonse mawaya olumikizira kuti muwonetsetse kuti palibe kusinthasintha kapena dzimbiri.
Ngakhale kuti sipika yamphamvu ya galimotoyo ndi yaying'ono, ndi "zenera la mzimu" la makina amawu. Kumvetsetsa ntchito yake komanso kudziwa njira zothetsera mavuto ndi kukonza kungatsimikizire kuti nyimbo iliyonse yomwe ikuimbidwa mkati mwa galimotoyo ndi yomveka bwino komanso yosangalatsa, zomwe zimapangitsa kuti ulendo woyendetsa galimotoyo ukhale wosangalatsa kwambiri.
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.
