Kodi subwoofer yagalimoto ndi chiyani?
Subwoofer ya galimoto ndi gawo lofunika kwambiri mu dongosolo la mawu a galimoto lomwe limayang'anira makamaka kupanga mawu otsika (nthawi zambiri kuyambira 20Hz mpaka 250Hz). Ntchito yake yayikulu ndikusintha ma signal amagetsi kukhala mafunde otsika kuti apereke zotsatira za besi monga kulira kwa drumbo, besi, ndi kulira kwa injini, zomwe zimapangitsa kuti mawu a nyimbo kapena mafilimu azimveka bwino komanso azimveka bwino.Youdaoplaceholder0 Ponena za kapangidwe ndi mfundo yogwirira ntchito, cholankhulira cha basi cha galimoto nthawi zambiri chimakhala ndi makina amphamvu amagetsi (monga maginito, ma coil a mawu), makina ogwedera (monga ma diaphragms, mafunde a masika), ndi makina othandizira chimango. Chimapanga mphamvu ya maginito poyendetsa mawu kudzera mu kusintha kwa mphamvu yamagetsi, zomwe zimapangitsa kuti diaphragm igwedezeke ndikukankhira mpweya kuti upange mawu. Nthawi zambiri imagwiritsa ntchito ma cones okhuthala a mapepala ndi ma coil olimbikitsidwa kuti ikwaniritse kufunikira kwa ma amplitude akuluakulu otsika, kuphatikiza tweeter (yomwe imayang'anira gawo la ma frequency apamwamba).
Mu makina olankhulira agalimoto, malo oyika a subwoofer (monga pakhomo lagalimoto, pansi kapena mu kabati yodzipereka) adzakhudza mphamvu ndi malo a bass. Chifukwa cha zoletsa zamtengo wapatali, makina olankhulira agalimoto oyambilira nthawi zambiri amakhala ndi ma speaker athunthu okha, zomwe zimapangitsa kuti bass ikhale yopyapyala. Kukhazikitsa subwoofer yodzipereka kungathandize kwambiri kumvetsera. Nthawi zambiri imagwira ntchito limodzi ndi crossover kapena imaphatikizidwa mu subwoofer kuti iwonjezere mphamvu ya frequency yotsika kwambiri.
Subwoofer yomwe ili mgalimoto ndi gawo la pulogalamu yamawu yomwe imayang'anira makamaka kupanga mawu otsika (nthawi zambiri kuyambira 20Hz mpaka 200Hz). Ntchito yake yayikulu ndikuwonjezera mayankho otsika, zomwe zimapangitsa kuti mawu a nyimbo ndi makanema azikhala osavuta komanso osangalatsa.
Subwoofer iyi imatha kukulitsa kwambiri luso la kumva . Mwa kubwereza zinthu zotsika kwambiri monga kulira kwa drumbo ndi bass, zimapangitsa kuti nyimbo ikhale yamphamvu kwambiri komanso mlengalenga ukhale wodabwitsa kwambiri. Makamaka posewera nyimbo zamagetsi kapena makanema ochitapo kanthu, imatha kupanga kukhudzika ndi kukhudza.
Mu malo odzaza phokoso, sipika ya bass imatha "kubisa" kusokoneza kwa ma frequency otsika . Phokoso la injini ndi phokoso la mphepo lomwe limapangidwa ndi galimoto panthawi yogwira ntchito nthawi zambiri limakhala pansi pa 200Hz, zomwe zimatha kubisa mosavuta gawo la ma frequency otsika a nyimbo. Subwoofer imaphimba phokosoli powonjezera kuthamanga kwa mawu otsika ndikubwezeretsa bwino nyimbo.
Kuchokera pamalingaliro aukadaulo, subwoofer imagwiritsa ntchito diaphragm yayikulu komanso makina amphamvu amagetsi kuti iyendetse mpweya wambiri, zomwe zimapangitsa kuti phokoso likhale lolimba komanso mawonekedwe osakhalitsa. Kukonza kapangidwe ka kabati kungathandizenso kukulitsa kufalikira kwa ma frequency otsika, zomwe zimapangitsa kuti bass ikhale yodzaza.
Kulephera kugwira ntchito kwa subwoofer ya galimoto kungayambitsidwe ndi zinthu zosiyanasiyana. Zotsatirazi zikupereka malingaliro ndi njira zothetsera mavuto kutengera zochitika zodziwika. Tikulangiza kuyamba ndi zinthu zosavuta ndikufufuza pang'onopang'ono mozama.
Njira zothetsera mavuto za Youdaoplaceholder0: Choyamba, tsimikizirani kukula kwa vuto ndikuwona ngati dongosolo lonse la honi ya galimoto silikugwira ntchito bwino kapena gawo lokha la bass ndi losazolowereka. Kuwunika kulumikizana kwa dera la Youdaoplaceholder0 kumaphatikizapo:
Onetsetsani ngati fuse yaphulika (mwachitsanzo, fuse ya HORN ya BYD F3 ili m'bokosi la fuse lakumanzere la nyumba ya dalaivala, lolembedwa kuti "Horn", ndi mphamvu yamagetsi ya 15A). Ngati yaphulika, iyenera kusinthidwa ndipo chifukwa cha short circuit chiyenera kufufuzidwa.
Onetsetsani ngati ma speaker terminal blocks ndi otayirira kapena okosijeni ndipo onetsetsani kuti pulagi ndi yolimba.
Kuyang'anira thupi la wokamba nkhani wa Youdaoplaceholder0 kungachitike m'njira zotsatirazi:
Yesani kukana kwa ma speaker terminals ndi multimeter. Mtengo wabwinobwino ndi pafupifupi 3 mpaka 5 ohms. Ngati ikuwonetsa infinity (OL), coil yamkati ikhoza kutenthedwa.
Dinani batani la honi kwa nthawi yayitali, ndipo mvetserani pafupi ndi honi kuti muwone ngati pali phokoso la "tap-tap". Ngati palibe phokoso, zimasonyeza kuti honi yawonongeka ndipo ikufunika kusinthidwa. Ngati palibe phokoso, yang'anani kwambiri pakuyang'ana dera lomwe likuyenda.
Mukayang'ana mzere ndi zinthu zakunja, chonde dziwani:
Yang'anani ngati mawaya ndi akale, awonongeka kapena sakugwirizana bwino, makamaka kasupe wa wotchi (tsitsi la tsitsi) pansi pa chiwongolero, chomwe chimasweka chifukwa chozungulira pafupipafupi.
Pewani kugwiritsa ntchito mfuti yamadzi mwachindunji pa hutala mukamatsuka galimoto kuti madzi asalowe ndikuyambitsa dzimbiri.
Kukhazikitsa kwa makina amawu a Youdaoplaceholder0 ndi zinthu zina zosamalira akatswiri:
Sinthani choyezera mawu kuti muwonetsetse kuti voliyumu ya bass siikutsekedwa kapena kuyikidwa pansi kwambiri.
Ngati pali kukayikira kuti pali vuto ndi amplifier yamagetsi kapena subwoofer, zida zaukadaulo zimafunika kuti muyese mphamvu yotulutsa.
Ngati vutoli likupitirira mutadzifufuza nokha, tikukulimbikitsani kuti mulankhule ndi akatswiri okonza kuti mupewe kuwonongeka kwina komwe kumachitika chifukwa cha opaleshoni yakhungu.
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.
