Wokamba nkhani awiri ali ndi okamba awiri, subwoofer ndi tweeter. Subwoofer ndi tweeter zimasiyanitsidwa ndi crossover ndipo zimagwirizanitsidwa ndi subwoofer ndi tweeter motsatana.
Maluso Akufananira Oyankhula Pamzere Ozungulira ndi Amplifiers Amagetsi
Mumachitidwe amawu omvera, zofananira zokhazokha ndi zolondola ndizomwe zimatha kupangitsa kulira kwamphamvu, makamaka kwa oyankhula pamzere. Kufanana kwama amplifiers amagetsi ndikofunikira kwambiri. Lero, Ding Taifeng Audio ikugawana nanu momwe mungasinthire ma amplifiers amagetsi olankhulira mzere.
1. Impedance iyenera kufanana
Kufananira kwa impedance kumatanthauza kuti kuchuluka kwa kutulutsa kwamphamvu kwamphamvu yamagetsi kuyenera kukhala kofanana ndi kuyimitsidwa kwamphamvu kwa wolankhulira mzere. The linanena bungwe impedance wa ochiritsira amplifiers mphamvu ambiri amathandiza 8Ω ndi 4Ω, ndi ena amphamvu amplifiers kuthandiza 2Ω. Kutulutsa kwakanthawi kwamayankhulidwe amizere kumasiyanasiyana kuyambira 16Ω mpaka 8Ω. Ngati oyankhula awiri okhala ndi mizere agwiritsidwa ntchito chimodzimodzi kulumikizana ndi njira imodzi, kutayika kwa wokamba nkhani kumakhala 16Ω. Zimakhala 8Ω, ndi zina zotero. Chifukwa chake, kutulutsa kwamphamvu kwa wolankhulira mzere ndi kuchuluka kwa kulumikizana kofananira kuyenera kufanana ndi kutulutsa kwamphamvu kwamphamvu yamagetsi.
Chachiwiri, mphamvu iyenera kufanana
Muyeso wapaderadera wamagetsi wamagetsi ndi magawidwe amagetsi oyankhulira mzere ndikuti pamikhalidwe ina yamagetsi, mphamvu yoyeseza yamphamvu yamagetsi iyenera kukhala yayikulu kuposa mphamvu yoyeseza yolankhula pamzere, komanso mphamvu yamagetsi yamagetsi pamsonkhano malo olimbikitsira mawu ayenera kukhala 1.2-1.5 kuposanso mphamvu yoyeseza yolankhulira yolankhulira. Mphamvu yomwe idavoteledwa iyenera kukhala nthawi 1.5-2 yamphamvu yoyesedwa ndi wokamba nkhani pamizere yayikulu pakakhala mphamvu yayikulu. Tchulani muyeso uwu wamakonzedwe, omwe samangowonetsetsa kuti zokulitsira mphamvu zimagwira ntchito bwino, komanso kuonetsetsa kuti olankhula pamzerewo ali otetezeka.
3. Mzere wolumikizana pakati pa chopangira mphamvu ndi cholankhulira cha mzerewu uyenera kufanana
Chingwe cholankhulira chikuyenera kukhala chachifupi momwe zingathere malinga ndi mphamvu yoyeseza ya wokamba nkhani pamzere, ndipo chingwe cholimba chamkuwa cholankhulira choyenera chimayenera kuzindikiritsidwa mosamala polumikiza. Pulagi yamayankhulidwe olankhulira nthawi zambiri amakhala akatswiri anayi kapena anayi-oyankhula Olankhulira omwe amakhala pamwamba pachimake amakhala ndi zolemba zazing'ono kwambiri, chifukwa chake samalani mukamalumikiza zingwe.
