Kulumikizana koyenera ndi kukhazikitsa kwa tweeter

⭐ ⭐ ⭐ ⭐ ⭐ Mukukhazikitsa makina atsopano oyankhula, mwiniwake akhoza kukhala ndi ntchito yotsatirayi - momwe mungalumikizire ma tweeters (tweeters) kuti azigwira ntchito bwino komanso popanda mavuto?

Chofunikira pa nkhaniyi ndizovuta za chipangizo chamakono cha stereo. Pazifukwa izi, pochita, nthawi zambiri pamakhala zochitika pomwe ma tweeter omwe adayikidwa amatha kugwira ntchito mopotoza kapena sagwira ntchito konse. Potsatira malamulo oyika, mungathe kupewa zovuta zomwe zingatheke - ndondomekoyi idzakhala yofulumira komanso yosavuta momwe mungathere.

Kodi tweeter ndi chiyani?

Ma tweeters amakono ndi mtundu wa magwero omveka, omwe ntchito yake ndi kuberekanso gawo lapamwamba kwambiri. Chifukwa chake, amatchedwa - okamba ma frequency apamwamba kapena ma tweeters. Tiyenera kuzindikira kuti, pokhala ndi kukula kophatikizana ndi cholinga china, ma tweeters ndi osavuta kukhazikitsa kusiyana ndi oyankhula akuluakulu. Amapanga phokoso lolunjika, ndipo ndi osavuta kuyikapo kuti apange tsatanetsatane wamtundu wapamwamba komanso kuwonetsera kolondola kwa phokoso, zomwe omvera amamva nthawi yomweyo.

Kodi tikulimbikitsidwa kukhazikitsa ma tweeters?

Opanga amalimbikitsa malo ambiri komwe ma tweeters amatha kuyikidwa, nthawi zambiri pamakutu. M’mawu ena, alozetseni m’mwamba momwe mungathere kwa omvera. Koma si onse amene amavomereza maganizo amenewa. Kukhazikitsa uku sikumakhala kothandiza nthawi zonse. Zimatengera zochitika zenizeni. Ndipo chiwerengero cha options unsembe ndi lalikulu ndithu.

Mwachitsanzo:

• Magalasi ngodya. Paulendo, sangabweretse kukhumudwa kwina. Komanso, zidzakwanira bwino mkati mwa galimotoyo;
• Dashboard. Kuyika kungatheke ngakhale ndi tepi ya mbali ziwiri;
• Podium. Pali njira ziwiri apa. Yoyamba ndikuyika ma tweeters pa podium wokhazikika (yomwe imabwera ndi tweeter), yachiwiri ndikudzipangira nokha podium. Chotsatirachi ndi chovuta kwambiri, koma chimatsimikizira zotsatira zabwino.

Malo abwino kwambiri otumizira ma tweeters ndi ati?

Mukamapanga zomvera zamagalimoto, mutha kusankha chimodzi mwazinthu ziwiri:

1. tweeter iliyonse imalunjika kwa omvera. Ndiko kuti, squeaker yoyenera imatumizidwa kwa dalaivala, kumanzere - komanso kwa iye;
2. mawonekedwe a diagonal. Mwa kuyankhula kwina, tweeter yomwe ili kumanja imayendetsedwa kumpando wakumanzere, pamene wokamba nkhani wakumanzere amapita kumanja.

Kusankhidwa kwa njira imodzi kapena ina kumadalira zomwe mwiniwake amakonda. Poyamba, mutha kuwongolera ma tweeters kwa inu, ndiyeno yesani njira ya diagonal. Pambuyo poyesa, mwiniwakeyo adzasankha kusankha njira yoyamba, kapena kusankha yachiwiri.

Maulalo Akulumikizana

Ma tweeter ndi gawo la stereo system yomwe ntchito yake ndikutulutsa mawu pafupipafupi 3000 mpaka 20 hertz. Chojambulira pawayilesi chimapanga ma frequency osiyanasiyana, kuyambira ma hertz asanu mpaka 000 hertz.

The tweeter imatha kutulutsa mawu apamwamba agalimoto, ma frequency omwe amakhala osachepera zikwi ziwiri hertz. Ngati chizindikiro chochepa chafupipafupi chikugwiritsidwa ntchito kwa icho, sichidzasewera, ndipo ndi mphamvu yaikulu yokwanira yomwe oyankhula apakati ndi otsika amapangidwira, tweeter ikhoza kulephera. Panthawi imodzimodziyo, sipangakhale funso la mtundu uliwonse wa kusewera. Kuti mugwire ntchito yokhazikika komanso yodalirika ya tweeter, muyenera kuchotsa zigawo zotsika kwambiri zomwe zilipo pagulu lonse. Ndiye kuti, onetsetsani kuti ma frequency ogwiritsira ntchito omwe amalimbikitsidwa okha ndi omwe agwera pa izo.

Njira yoyamba komanso yosavuta yochepetsera gawo lotsika kwambiri ndikuyika capacitor mndandanda. Imadutsa bwino band yapamwamba kwambiri, kuyambira ma hertz zikwi ziwiri ndi zina zambiri. Ndipo samadutsa ma frequency pansi pa 2000 Hz. M'malo mwake, iyi ndiye fyuluta yophweka, zomwe zingatheke ndizochepa.

Monga lamulo, capacitor ilipo kale mu dongosolo la okamba nkhani, kotero sikuyenera kugulidwa kuwonjezera. Muyenera kuganizira zogula ngati mwiniwakeyo adaganiza zopeza wailesi yogwiritsidwa ntchito, ndipo sanapeze capacitor mu tweeter kit. Zitha kuwoneka motere:

• Bokosi lapadera lomwe chizindikiro chimayikidwa ndikutumizidwa mwachindunji kwa ma tweeters.
• Capacitor imayikidwa pa waya.
• Capacitor imamangidwa mwachindunji mu tweeter yokha.

Ngati simunawone chilichonse mwazomwe zatchulidwazi, muyenera kugula capacitor padera ndikuyiyika nokha. M'masitolo a wailesi, ma assortment awo ndi aakulu komanso osiyanasiyana.

Ma frequency osefedwa amatengera mtundu wa capacitor woyikidwa. Mwachitsanzo, mwiniwake akhoza kuyika capacitor yomwe ingachepetse kuchuluka kwa ma frequency operekedwa kwa olankhula ku hertz zikwi zitatu kapena zinayi.

Zindikirani! Kuchuluka kwa ma frequency a siginecha yomwe imaperekedwa kwa tweeter, mwatsatanetsatane momwe phokoso limatha kukwaniritsa.

Pamaso pa njira ziwiri, mutha kupanga chisankho mokomera cutoff kuchokera ku hertz ziwiri mpaka zinayi ndi theka.

 Kulumikizana

Kulumikizana kwa tweeter kuli motere, kumalumikizidwa mwachindunji ndi wokamba nkhani yomwe ili pakhomo panu, kuphatikiza tweeter imalumikizidwa ndi kuphatikiza kwa speaker ndi minus mpaka minus, pomwe capacitor iyenera kulumikizidwa ndi kuphatikiza. . Kuti mudziwe zambiri za mtundu wa waya womwe uli woyenerera ndime iti, onani chithunzi cholumikizira wailesi. Uwu ndi upangiri wothandiza kwa iwo omwe sadziwa kulumikiza ma tweeters popanda crossover.

Njira ina yolumikizirana ndiyo kugwiritsa ntchito crossover. Mu zitsanzo zina zamalankhulidwe kachitidwe ka magalimoto, izo zaphatikizidwa kale mu zida. Ngati palibe, mutha kugula padera.

Zina

Mpaka pano, njira yodziwika bwino ya tweeter ndi electrodynamic system. Mwadongosolo, imakhala ndi nyumba, maginito, koyilo yokhala ndi mafunde, diaphragm yokhala ndi nembanemba ndi mawaya amagetsi okhala ndi ma terminals. Chizindikiro chikagwiritsidwa ntchito, pakali pano ikuyenda mu coil, gawo lamagetsi limapangidwa. Imalumikizana ndi maginito, kugwedezeka kwamakina kumachitika, komwe kumatumizidwa ku diaphragm. Chotsatiracho chimapanga mafunde acoustic, phokoso limamveka. Pofuna kukulitsa luso la kutulutsa mawu, nembanemba imakhala ndi mawonekedwe ake enieni. Kuti mupeze kukhazikika kowonjezera, nembanemba imayikidwa ndi gulu lapadera. Silika amadziwika kuti amatha kupirira katundu wambiri, kusintha kwa kutentha komanso chinyezi. Mutha kukumana ndi izi pamakina apamwamba kwambiri acoustic. M'makina omvera agalimoto wamba, amakumana kawirikawiri.

Njira yotsika mtengo kwambiri ndi membrane yamapepala.

Kuphatikiza pa mfundo yakuti phokosolo ndi loipa kuposa momwe zinalili kale, zipangizo zoterezi zimakhala ndi moyo waufupi kwambiri. Ndipo izi sizosadabwitsa, chifukwa pepala silingatsimikizire kugwira ntchito kwapamwamba kwa tweeter mumikhalidwe yotsika kutentha, chinyezi chambiri komanso katundu wambiri. Pamene makina akuwonjezera liwiro la injini, phokoso lachilendo likhoza kumveka.

Musaiwale kuti mutha kukhazikitsanso buzzer pogwiritsa ntchito wailesi. Ngakhale zitsanzo zotsika mtengo zimatha kusintha maulendo apamwamba. Makamaka, mitundu yamitengo yapakati imakhala ndi zofananira, zomwe zimathandizira kwambiri ntchitoyi.

Pambuyo kukhazikitsa tweeter, muyenera kukhazikitsa zomvetsera, ndi momwe mungachitire izi, werengani nkhani yakuti "Momwe mungakhazikitsire wailesi".

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.
