Momwe mungalumikizire ma tweeters ndi crossover ndi amplifier?

Tekinoloje yafika patali kuyambira pomwe tweeter yanga yoyamba idakhazikitsidwa zaka 15 zapitazo, ndipo ma tweeter ambiri amakono akubwera ndi crossover yomangidwa. Koma mukhoza kupeza ena popanda crossover. Muzochitika izi, ngati mukudziwa kufunikira kwa crossover, mukudziwa kuti simudzayika ma tweeters popanda iwo. Lero ndikuyang'ana momwe mungalumikizire ma crossover tweeter ndi amplifier.

Nthawi zambiri, kuti mulumikizane ndi tweeter yokhala ndi cholozera cholumikizidwa ndi amplifier, tsatirani izi.

• Choyamba, gwirizanitsani waya wabwino wa crossover ku terminal yabwino ya amplifier.
• Kenako lumikizani waya woyipa wa crossover ku terminal yoyipa ya amplifier.
• Kenako gwirizanitsani malekezero ena a crossover ku tweeter (zabwino ndi zoipa).
• Pomaliza, gwirizanitsani madalaivala ena monga woofers kapena subwoofers ku amplifier.

Ndizomwezo. Tsopano makina anu omvera agalimoto azigwira bwino ntchito.

Kudziwa kofunikira pa ma tweeters ndi ma crossovers

Tisanayambe njira yolumikizira, ndikofunikira kukhala ndi chidziwitso chokhudza ma tweeters ndi ma crossovers.

Kodi tweeter ndi chiyani?

Kuti mupangitse ma frequency apamwamba a 2000-20000 Hz, mufunika tweeter. Ma tweeters awa amatha kusintha mphamvu zamagetsi kukhala mafunde amawu. Kuti achite izi, amagwiritsa ntchito electromagnetism. Nthawi zambiri ma tweeters ndi ang'onoang'ono kuposa ma woofers, subwoofers ndi madalaivala a midrange.

woofers: Mawoofers amatha kupanga ma frequency kuchokera ku 40 Hz mpaka 3000 Hz.

Ma Subwoofers: Kuthekera kopanganso ma frequency kuchokera ku 20 Hz mpaka 120 Hz.

Madalaivala a Midrange: Kuthekera kopanganso ma frequency kuchokera ku 250 Hz mpaka 3000 Hz.

Monga momwe mungaganizire, makina anu amawu amagalimoto amafunikira madalaivala awiri kapena kupitilira apo. Apo ayi, sichidzatha kugwira ma frequency ena.

Kodi crossover ndi chiyani?

Ngakhale madalaivala olankhula zigawo adapangidwa kuti azitulutsa pafupipafupi, madalaivalawa sangathe kusefa ma frequency. Kwa ichi muyenera crossover.

Mwanjira ina, crossover imathandizira ma tweeter kujambula ma frequency pakati pa 2000-20000 Hz.

Momwe mungalumikizire ma tweeters ku Ma crossover omangidwa mu amplifier

Kutengera momwe mulili, mungafunike kutenga njira zosiyanasiyana polumikiza tweeter yanu. Mwachitsanzo, ma tweeters ena ali ndi ma crossovers omwe adamangidwa ndipo ena alibe. Chifukwa chake, mu njira 1, tikambirana ma crossover omangidwa. Tidzayang'ana pa ma crossovers odziyimira pawokha munjira 2, 3 ndi 4.

Njira 1 - tweeter yokhala ndi crossover yomangidwa

Ngati tweeter ibwera ndi crossover yomangidwa, simudzakhala ndi vuto kukhazikitsa tweeter ndikuyilumikiza. Lumikizani chotsogolera chabwino cha tweeter kumapeto kwa amplifier. Kenaka gwirizanitsani waya wotsutsa ku mapeto oipa.

Kumbukirani: Mwanjira iyi, crossover imasefa ma frequency a tweeter. Sizithandizira madalaivala ena monga woofers kapena subwoofers.

Njira 2 - Kulumikiza Tweeter Molunjika kwa Amplifier ndi Crossover ndi Full Range speaker

Mwanjira iyi, muyenera kulumikiza crossover molunjika ku amplifier. Kenako gwirizanitsani malekezero ena a crossover ku tweeter. Kenaka, timagwirizanitsa madalaivala ena onse malinga ndi chithunzi pamwambapa.

Njira iyi ndi yabwino kulumikiza crossover yosiyana ndi tweeter. Komabe, crossover imangothandizira tweeter.

Njira 3 - Kulumikiza tweeter pamodzi ndi wokamba nkhani

Choyamba, gwirizanitsani waya wabwino wa choyankhulira chathunthu ku amplifier.

Kenako tsatirani njira yomweyo kwa waya woipa.

Kenako gwirizanitsani mawaya abwino ndi oipa a crossover ku malekezero abwino ndi oipa a wokamba nkhani.

Pomaliza, gwirizanitsani tweeter ku crossover. Iyi ndi njira yabwino yopulumutsira waya wina wolankhula.

Njira 4 - kulumikizana kosiyana kwa tweeter ndi subwoofer

Ngati mukugwiritsa ntchito subwoofer yokhala ndi tweeter, alumikizani padera ndi amplifier. Kupanda kutero, kutulutsa kwakukulu kumatha kuwononga kapena kuphulika tweeter.

Choyamba, gwirizanitsani waya wabwino wa crossover ku terminal yabwino ya amplifier.

Kenaka gwirizanitsani waya wotsutsa ku mapeto oipa. Kenako gwirizanitsani tweeter ku crossover. Onetsetsani kulumikiza mawaya molingana ndi polarity.

Tsopano gwirizanitsani mawaya abwino ndi oipa a subwoofer ku njira ina yokulitsa.

Malangizo ena omwe angathandize njira zomwe zili pamwambazi

Ma amplifiers amakono amagalimoto ali ndi mayendedwe a 2 mpaka 4. Ma amplifiers amatha kuyendetsa nthawi imodzi 4 ohm tweeter ndi 4 ohm full range speaker (akalumikizidwa mofanana).

Ma amplifiers ena amabwera ndi ma crossover omangidwa. Mutha kugwiritsa ntchito ma crossovers omangidwawa popanda vuto lililonse. Nthawi zonse gwiritsani ntchito crossover tweeter. Komanso, musalumikizane ndi tweeter ndi subwoofer.

Kwa iwo omwe akufuna kukwezedwa, nthawi zonse ndikwabwino kusintha crossover yoyambirira ndi crossover yokhala ndi 2-way speaker.

Zomwe muyenera kuziganizira panthawi ya waya

Popanda mawaya oyenera, simungathe kulumikiza ma tweeter, crossovers, kapena subwoofers moyenera. Chifukwa chake, tsatirani malangizo awa kuti mupeze zotsatira zabwino.

• Osasokoneza ma polarities a mawaya. Mu zitsanzo pamwambapa, mungafunike kuthana ndi mawaya 4 kapena 6. Choncho, dziwani mawaya molondola ndikugwirizanitsa mawaya moyenerera. Mizere yofiira imayimira mawaya abwino ndipo mizere yakuda imayimira mawaya oyipa.
• Gwiritsani ntchito zolumikizira crimp m'malo mwa tepi yamagetsi. Ndiwo njira zabwino kwambiri zopangira ma waya otere.
• Pali mitundu ingapo yolumikizira ma crimp pamsika. Choncho onetsetsani kugula yoyenera mawaya anu.
• Gwiritsani ntchito waya woyezera 12 mpaka 18. Kutengera mphamvu ndi mtunda, sikelo imatha kusiyana.
• Gwiritsani ntchito zida monga ma wire strippers ndi zida za crimping panthawi yolumikizira pamwambapa. Kukhala ndi zida zoterezi kungathandize kwambiri. Mwachitsanzo, chowombera waya ndi njira yabwino kwambiri kuposa mpeni wothandizira. (1)

Komwe mungayike ma tweeters

Ngati mukuyang'ana malo oti muyikepo tweeter, yesani kuyiyika pakati pa mipando ya okwera ndi oyendetsa.

Komanso, chitseko cha galimoto kapena mizati yam'mbali pafupi ndi galasi lamoto ndi malo abwino opangira tweeter. Ma tweeter ambiri oyika fakitale amayikidwa m'malo awa.

Komabe, mukakhazikitsa ma tweeters, onetsetsani kuti mwasankha malo oyenera. Mwachitsanzo, anthu ena sakonda kuyika tweeter pakati pa dashboard. Kumveka kosalekeza pafupi ndi makutu kumatha kuwakwiyitsa. Chitseko cha galimoto ndi malo abwino kwambiri pa izi. Komanso, mukamayika tweeter pakhomo la galimoto; Kubowola ndi kukhazikitsa njira zosavuta.

Kodi ndingagwiritse ntchito ma tweeter pa monoblock subwoofer?

Sub amp ya monoblock ili ndi njira imodzi yokha ndipo njirayo ndi yopangira bass. Monoblock amplifiers alibe ma frequency apamwamba. Chifukwa chake, simungathe kukhazikitsa tweeter pa monoblock amplifier.

Komabe, ngati mukugwiritsa ntchito amplifier yamachanelo ambiri okhala ndi crossover yotsika, tsatirani njira zomwe zili pansipa kuti mugwire bwino ntchito. (2)

• Mukamagwiritsa ntchito amplifier yamachanelo ambiri, nthawi zonse gwirizanitsani tweeter ku tchanelo chathunthu chosagwiritsidwa ntchito.
• Ngati mukugwiritsa ntchito okamba, gwirizanitsani tweeter mofanana ndi okamba.
• Komabe, ngati palibe mayendedwe osagwiritsidwa ntchito mu amplifier, simungathe kulumikizana ndi twitter.

Langizo: Ma cross-pass crossover amaletsa ma frequency apamwamba ndikulola kuti ma frequency a 50 Hz mpaka 250 Hz agwiritsidwe ntchito.

Kufotokozera mwachidule

Kaya mumagula tweeter yokhala ndi crossover yokhazikika kapena crossover yosiyana, muyenera kulumikiza tweeter ndi crossover ku amplifier. Njira yabwino yochitira izi ndikulumikiza tweeter ku njira yosagwiritsidwa ntchito.

Kumbali ina, ngati mukugwiritsa ntchito subwoofer yokhala ndi tweeter, tsatirani malangizo omwe ali pamwambapa molondola.

Onani zina mwazolemba zathu pansipa.

• Momwe mungalumikizire ma tweeters popanda crossover
• Momwe mungalumikizire mabatire amgalimoto ambiri
• Momwe mungasiyanitsire waya wolakwika kuchokera ku zabwino
