Kuphweka koyeretsedwa kapena kuumitsa koyenera kuchita bwino?

Ukadaulo wa zokuzira mawu wasintha pazaka zana. Kale kumayambiriro kwa mbiri yake, zidapezeka kuti kukonzanso kwamtundu wonse wamayimbidwe, ndi kupotoza kokwanira, ndi wokamba m'modzi (transducer) ndizovuta kwambiri, ngati sizingatheke. Zinapezeka kuti kunali koyenera kupanga zokuzira mawu zokhala ndi ma transducer apadera pokonza magulu ena ang'onoang'ono.

Chitukuko chapita mbali iyi, ndipo ndi 99% ya opanga zokuzira mawu, kupanga chuma chosaneneka cha njira ziwiri, njira zitatu, zinayi komanso njira zambiri, nthawi zina zimakhala zovuta kwambiri, zowonjezereka, zowonjezereka - kapena anatulukira. Zikuwoneka kwa osachita masewera omwe amasindikiza kuti "misewu" yambiri imakhala yokonzeka bwino mwina ... kwa makasitomala oganiza bwino. Komabe, mayankho omveka amapambana, momwe kuchuluka kwa njira ndi kuchuluka kwa ma transducer (osati ofanana - pakhoza kukhala oposa transducer m'njira iliyonse, zomwe nthawi zambiri zimakhala mu gawo la LF) zimayenderana ndi kukula kwa kapangidwe ndi ntchito yake yomwe akufuna.

Minimum Bidromic

Zochepa zimatengedwa ngati zochepa zoonekeratu mayiko awiri dongosolo, kawirikawiri imakhala ndi midwoofer ndi tweeter. Dongosolo lotere, lotengera otembenuza apamwamba amitundu yonse iwiri, amatha kugwira ntchito pafupifupi pafupifupi ma frequency osiyanasiyana. Komabe, zimakhala zovuta kwambiri kuti mukwaniritse ma voliyumu apamwamba kwambiri ndi iyo, chifukwa chapakati pawoofer, chomwe chimakhala chotalikirapo (kuti athe kuthana ndi ma frequency apakati), ngakhale atakhala ndi mabass, sangathe kuyamwa kwambiri. mphamvu mumtundu uwu, siingathe kuberekanso mabass nthawi imodzi mozama komanso mokweza. Monga tonse tikudziwa, mafupipafupi otsika kwambiri ndi mphamvu zambiri ndi oyankhula akuluakulu, omwe, komabe, sangathenso kugwira ntchito ngati midwoofers, koma ngati woofers, chifukwa cha kukula kwawo kwakukulu, komanso chifukwa cha zinthu zina, kuwapanga. zovuta kwambiri. oyenera kwambiri pokonza otsika, osati ma frequency apakati; Zotsatira zake, machitidwe amagulu atatu amapangidwa, pomwe ma frequency apakati amasinthidwa ndi chosinthira chapadera - midrange.

Nthawi imodzi "optimum"

Davis MV One - ali ngati amodzi, palibenso okamba pano.

Malamulo a masewera omwe amakulolani kuti mupange zokuzira mawu apamwamba sali okhwima, koma malamulo onse, monga momwe zimakhalira, amakhazikitsidwa ndikugwiritsidwa ntchito ndi okonza ambiri - ndithudi, kuti apambane, osati molingana ndi ena. maphikidwe. Koma monga pali ena omwe amakonda kukokomeza ndi "permeability" ndi kusokoneza makonzedwe owonjezera, pali omwe amalimbikira kuyesetsa kuphweka, kuyesetsa kukwaniritsa. wapamwamba kwambiri - zokuzira mawu zanjira imodzi komanso zosinthira kumodzi. Choncho ndi wokamba mmodzi mmodzi.

Zachidziwikire, tikudziwa zida zodziwika bwino, makamaka zazing'ono, zamakompyuta kapena zosunthika zomwe zilibe malo kapena bajeti yoyika njira yolankhulira njira ziwiri. Chifukwa chake timasiya kugwira ntchito ndi dalaivala m'modzi (mu tchanelo chilichonse cha stereo, bola ngati chipangizocho chili stereo), nthawi zambiri chimakhala chaching'ono, masentimita angapo, chomwe sichimakwaniritsa ngakhale miyezo yakale kwambiri ya zida za hi-fi, koma sichoncho. zida. amene amati dzina ili.

Chochititsa chidwi kwambiri ndi mapangidwe a njira imodzi, yomwe, malinga ndi omwe amawapanga, ndipo, mwa lingaliro la ogwiritsa ntchito ambiri, amangoyenera kukhala abwino kusiyana ndi machitidwe ambiri, ndi kuwoneka mu osankhika chandamale, pamitengo ya makumi angapo masauzande a zł.

M'nkhani yotsutsanayi, tidzayesa kukhala ndi cholinga. Zoonadi, ziwerengerozo zimasonyeza kuti machitidwe a magulu ambiri amayamikiridwa kwambiri ndi okonza anzeru padziko lonse lapansi, koma tiyeni tiyimire "mbali imodzi yabwino." Osachepera kuti akumbutse okonda mapangidwe ovuta kwambiri kuti kuchulukitsa si mapeto mwa iwo okha, koma kufunikira komvetsa chisoni ndi kusankha kochepa kwa zoipa. Zinthu zikadakhala zokondweretsa kwambiri ngati kukanakhala kotheka kuti gulu lonselo ligwiritse ntchito zokuzira mawu limodzi, monga kugawidwa kwa gululo kukhala magulu ang'onoang'ono, i.e. kuyambitsa ma electrostatic precipitators (crossover), lakwitsidwa. Kutulutsa kwamagulu osiyanasiyana afupipafupi ndi zokuzira mawu omwe ali pafupi ndi mzake, koma osati pa olamulira omwewo (kupatulapo machitidwe a coaxial, omwe ali ndi zovuta zina ...) amachititsa mavuto ena. Komabe, zimazindikirika kuti ndi zofunikira zapamwamba, izi sizikhala zovuta kuposa momwe angagwiritsire ntchito dalaivala mmodzi. Nthawi zonse ndi bwino kukumbukira kuti sizomveka kuchulukitsa mosafunikira - muyenera sungani "patency" mkati mwa chifukwa ndi zosowa zamapangidwe omwe ali ndi ntchito zinazake ndi magawo omwe mukufuna.

Ndikosatheka kupanga dalaivala wangwiro wathunthu, komanso ngakhale wabwino (poyerekeza ndi kuthekera kwa okamba)

zimafuna chilakolako chachikulu, luso komanso kugwiritsa ntchito zipangizo zabwino kwambiri. The 20 DE 8 full range loudspeaker (yomwe imagwiritsidwa ntchito mu MV One) imaphatikizapo, mwa zina, makina okwera mtengo a Alnico maginito.

M'malo mwake, choyenera chingakhale chokweza mawu chabwino chomwe chimathetsa mavuto onse obwera chifukwa cha kuchulukana. Tsoka ilo, chokweza chotere, kapena "pafupifupi" chokweza chotere, ngakhale kuyesetsa kosalekeza, kulibe. Onse, ngakhale olankhula bwino kwambiri amakhala ndi bandwidth yocheperako kuposa zokuzira mawu ambiri, ndipo machitidwe awo amawonetsa kusagwirizana kwambiri. Izi, komabe, sizikhumudwitsa anthu ena, chifukwa mwina kudzipangira hypnosis kapena katundu weniweni wa transducer apamwamba kwambiri amawalola kuti azindikire zosiyana ndi mawu awo, chinachake chapadera, choncho, malinga ndi mafani a yankho lotere. , china chake chabwino. Komanso, mbali zina za mabwalo a mbali imodzi zimakopa chidwi cha eni ake amplifiers a chubu - i.e. nthawi zambiri amplifiers otsika mphamvu, omwe motero safuna zokuzira mawu amphamvu kwambiri, koma ndikuchita bwino kwambiri. Chowonadi ndi chakuti ngati chokweza mawu sichiyenera kukhala ndi mphamvu yayikulu, ndiye chifukwa cha mapangidwe omwe amagwirizana nawo (mwachitsanzo, kamvekedwe kakang'ono ka mawu), ndikosavuta kuti akwaniritse bwino kwambiri, komanso bandwidth yowonjezera. .

Konzani malingaliro anu

Chokuzira mawu chosangalatsa komanso chapamwamba kwambiri chidapangidwa ndi kampani yaku France ya Davis ndipo chimagwiritsidwa ntchito mu zokuzira mawu za MV One. Mayeso awo, m'gulu lamitundu itatu yaku France (ena awiriwa ndi magulu atatu), mwamwambo amafotokoza za kapangidwe, kamvekedwe ka mawu ndi labu, adasindikizidwa mu June (6/2015) nkhani ya Audio. Mutha kufananiza ndikupanga malingaliro anu ... Chinthu chosangalatsa, ngakhale popanda chubu amplifier.
