ACADEMY Chario SERENDIPITY
Academy Serendipity, ngakhale ali ndi zaka zopitilira khumi, sikuti amangokhalabe muzopereka za Chario, koma akadali pachimake. Mapangidwe a okamba awa ndi amtundu wina, ngakhale amachokera ku zomwe Chario adanenapo kale, olankhula a Academy Millennium Grand. Malingana ndi wopanga, Serendipity ndi mapeto a zochitika ndi malingaliro omwe amasonkhanitsidwa kuyambira pachiyambi cha kukhalapo kwa kampani, i.e. kuyambira 1975. Mtengo waukulu wamayimbidwe umabisika mu kasinthidwe kapadera komwe sikungadziwike kokha ndi chiwerengero cha okamba. ndi mitundu yawo yosiyanasiyana, koma ndi momwe amalumikizirana kunja kwa mawonekedwe a "multipath".
Thupilo limawoneka ngati ndodo yayikulu, koma izi ndizochepa chabe.
Chifukwa chake, makoma am'mbali ndi apamwamba amapangidwa ndi matabwa, pomwe kutsogolo, kumbuyo ndi kulimbitsa kwamkati kumapangidwa ndi fiberboard. Pali ambiri a iwo, makamaka mu gawo la subwoofer, pomwe pali mphamvu zambiri zotsalira kuti zisungunuke, pomwe zina zimagwira ntchito ngati magawo, kupanga zipinda zodziyimira pawokha zomwe zimagwira ntchito m'magulu osiyanasiyana. Chomera chonsecho chimagawidwa m'magawo awiri, ochulukirapo kapena ocheperako kutalika kwake. Pansi pali gawo la subwoofer, ndipo pamwamba pali madalaivala ena anayi. Chario samangoganizira za matabwa achilengedwe kuti akwaniritse phokoso lachilengedwe, makamaka kumamatira ku lingaliro la kupatsa okamba udindo wa "zida"; ndime iyenera kuyang'anizana, osati kusewera - izi ndi zinthu zosiyana. Mitengoyi, komabe, ili ndi magawo abwino amakina, ndipo chofunika kwambiri ... amachitidwa motere, amawoneka okongola.
Njira zisanu pazolinga zenizeni
Mgwirizano wamagulu asanu ndi wosowa. Ngakhale titawonjezera ma nuances ndipo, poganizira malingaliro ena, timavomereza kuti iyi ndi njira inayi ndi theka (yomwe idzasokoneza kusanthula kwambiri ...), tikulimbana ndi mapangidwe omwe amapita kutali. kupyola njira zomwe zimagwiritsidwa ntchito ndi opanga ena . Kulengedwa kwa mabwalo amtundu wa multiband kumakakamizika chifukwa cha kulephera kwa zokuzira mawu - kapena ngakhale awiriawiri a mitundu yosiyanasiyana ya madalaivala (mu maulendo awiri) - kupanga chipangizo chojambulira chomwe chidzapereka nthawi imodzi bandwidth yaikulu, mphamvu zambiri komanso kusokoneza kochepa. Koma kugawikana m'magulu atatu - otchedwa bass, midrange ndi treble - ndikokwanira kukwaniritsa pafupifupi magawo onse (zokamba zopangidwira kunyumba). Kukula kwina kungakhale chifukwa cha cholinga chokwaniritsa mikhalidwe ina ya sonic ndi katundu. Izi ndi momwe zimagwirira ntchito.
The ochuluka Serendipity wokamba dongosolo ntchito osati kukhathamiritsa processing wa munthu waung'ono osiyanasiyana amamvekedwe osiyanasiyana ma transducers apadera, komanso, chodabwitsa, kugwiritsa ntchito "mbali" zotsatira chifukwa cha ntchito Mipikisano gulu kachitidwe, amene ali. amaonedwa kuti ndi owopsa kwa opanga ena ndipo amachepetsedwa mpaka pamlingo wotheka. Wopanga Serendipity amayenda molunjika kosiyana ndi womanga monga Cabas, yemwe, mothandizidwa ndi makina okhazikika, akuyesera kuti akwaniritse zotsatira za "pulsating mpira", gwero logwirizana la ma frequency onse, kutulutsa mawonekedwe ofanana pa. ngodya yotakata kwambiri mu ndege iliyonse (chomwe ndicho cholinga cha dongosolo lokhazikika la otembenuza onse). Kusamuka kwa transducers wina ndi mzake kumabweretsa kusintha kwa makhalidwe kunja kwa olamulira waukulu (makamaka mu ndege yoyima yomwe kusamukaku kumachitika). Ngakhale kuti zododometsazi zikuwonekera pazikhalidwe ndi nkhwangwa zomwe zimapitirira kumvetsera, mafunde omwe akuyenda m'njira izi amawonekera pakhoma la chipindacho adzafikanso kwa omvera ndipo adzalemetsa kuzindikira kwa tonal ya chithunzi chonse. . Choncho, malinga ndi opanga ambiri, ndikofunika kukhalabe osasunthika, malingana ndi mafupipafupi, otchedwa mphamvu yankho.
Kumbali inayi, zochepetserazi zomwe zingatheke zikhoza kuonedwa ngati mwayi wabwino wochepetsera matalikidwe a mafunde owonetseredwa, ndiko kuti, kuchepetsa kuwonetsetsa ndikuthandizira pakupanga fano pa malo omvera. Kuyang'ana pa Serendipity, sitiwona "zosokoneza" zoonekeratu m'machitidwe olankhula. The tweeter ili pafupi ndi midrange, yomwe ili pafupi ndi midrange yachiwiri (yosefera pang'ono), yomwe, nayonso, imakhala moyandikana ndi bass. Komabe, kwa mafunde afupipafupi apakati pa pafupipafupi, omwe adzakhala mafunde a crossover pano, ngakhale mtunda woterewu pakati pa transducers umatanthauza kuti pamakona a madigiri angapo, ndipo zochulukirapo - makumi angapo, kutsika kwakuya kumawonekera pamakhalidwe. M'lifupi mwake zimadalira kutsetsereka kwa mapiri a makhalidwe a zigawo za munthu aliyense, zomwe zimagwirizana kwambiri ndi momwe okamba amagwirira ntchito pamodzi.
Apa pakubwera gawo lina la chithunzithunzi, chomwe ndi kugwiritsa ntchito kusefa kofewa. Chotsatira ndikuyika mafupipafupi a crossover pafupi ndi wina ndi mzake - pakati pa mabass ndi awiri a midrange woofers ndi pafupifupi 400 Hz, ndi pakati pa midrange (zosefedwa kwambiri) ndi tweeter - pansi pa 2 kHz. Kuphatikiza apo, pali mgwirizano pakati pa madalaivala apakati (omwe amasefedwa, koma mawonekedwe awo amakhala pafupi ndi wina ndi mnzake pamitundu yotakata kwambiri, ndipo ma midrange ocheperako amalumikizananso ndi tweeter) ndipo, pomaliza, tili ndi zambiri. zophatikizika ndi zophatikizika mawonekedwe. Zimakhala zovuta kudziwa zomwe zimayembekezeredwa (osati zofananira) za womanga pokhapokha panjira yayikulu muzochitika zotere, ndipo ndizosatheka kukhazikika pamakona akulu. Komabe, mlengi Chario ankafuna kukwaniritsa zimenezi - amachitcha "decoruration": attenuation wa ma radiation kuchokera olamulira waukulu, mu ndege ofukula, pofuna kuchepetsa kusinkhasinkha kuchokera pansi ndi padenga.
Kusintha kwa Woofer
Yankho lina lapadera lomwe likadali lokhudzana ndi kuwongolera kowunikira ndi kasinthidwe ka zokuzira mawu mumtundu wa subwoofer. Chigawo, chomwe wopanga amachitcha kuti sub, chili pansi kwambiri pa dongosolo. Mfundo apa si mbali zake zina (zimene zidzakambidwe pambuyo pake), koma chifukwa chakuti gwero la ma radiation lili pamwamba pa nthaka (tikhoza kuona "mazenera" amtundu wapansi, facade ndi sidewalls). Momwemonso, woofer amasiyidwa ndi kampaniyo kuchokera pansi mpaka pamtunda, mphuno imafanana ndi zomwe zimatchedwa zodziwika bwino. ma curve a isophonic, koma izi sizimatsatira (komanso) mfundo yosavuta yoti tiyenera "kuwongolera" katundu wakumva kwathu motere (zomwe sitizikonza ndi zida zilizonse zomvera pomvera kumveka kwachilengedwe ndi nyimbo zamoyo). Kufunika kowongolera uku Chario amachokera kuzinthu zosiyanasiyana zomwe timamvera nyimbo - kukhala ndi kunyumba, kuchokera kwa okamba nkhani. Tikamamvetsera mafunde amoyo, olunjika ndi owonetseratu amafika kwa ife, zomwe pamodzi zimapanga chiwonetsero cha chilengedwe. Palinso zowonetsera mu chipinda chomvetsera, koma ndizovulaza (ndipo choncho Chario amawachepetsa pogwiritsa ntchito njira zomwe tafotokozazi), chifukwa. pangani zotsatira zosiyana kotheratu, osapanganso mawonekedwe amawu ojambulira, koma chifukwa cha machitidwe amawu a chipinda chomvera. Mbali za malo ojambulira ojambulira amazingidwa ndi mawu omwe amaseweredwa kudzera pa zokuzira mawu molunjika (monga kubweza). Tsoka ilo, amangochokera kumbali ya zokuzira mawu, ndipo ngakhale kusintha kwa magawo komwe kungathe kukulitsa ndi kukulitsa malo athu sikungathetseretu vutoli. Malinga ndi kafukufuku wa Chario, malingaliro athu amayang'ana kwambiri ma frequency apakati, omwe amafunikira kuchepetsedwa pang'onopang'ono kuti tipeze mwachilengedwe momwe zimamvekera pamawu onse, ponse pawiri pamayendedwe a tonal ndi malo.
Wina akakoka, wina amakankha
Mapangidwe a gawo la Serendipity subwoofer ndi mutu wokha. Pano tikuyang'anizana ndi kachitidwe kakankha-koka, komwe sikumagwiritsidwa ntchito kawirikawiri (mwanjira ina yotakata, yotchedwanso gulu kapena isobaric). Awa ndi mawoofer olumikizidwa mwamakina "diaphragm ku diaphragm" ndi magetsi m'njira yoti ma diaphragms awo amasuntha mbali imodzi (yachibale ndi thupi, osati mabasiketi amodzi). Choncho, mphamvuzi sizimakanikiza mpweya wotsekedwa pakati pawo (motero dzina lakuti isobaric), koma lisunthire. Kuti achite izi, ngati ali ndi mawonekedwe ofanana ndendende ndipo matembenuzidwe amalangidwa mbali imodzi, ayenera kulumikizidwa mosiyana (kwa wina ndi mnzake) polarities (polemba malekezero awo) kuti pamapeto pake azigwira ntchito mugawo lomwelo (pamene koyilo imazama imodzi) mu maginito, koyilo ya winayo imatuluka). Chifukwa chake dzina loti Kankhani-kukoka - pamene wokamba wina "akukoka", wina "amakankhira", koma amagwirabe ntchito mofanana. Kusintha kwina pamakonzedwe awa ndi makonzedwe a maginito-to-maginito, ndipo china chomwe chimagwira ntchito mofanana ndi mphamvu ya sonic ndi dongosolo lomwe oyankhula amayikidwa kuseri kwa mzake mbali imodzi (maginito akunja moyandikana ndi maginito). khomo lamkati). Ndiye okamba ayenera kulumikizidwa mu polarity yemweyo - dongosolo loterolo, ngakhale akadali "isobaric", sayenera kutchedwanso kukankha-kukoka, koma, mwinamwake, pawiri.
Ndilemba za kusiyana kwakung'ono pakati pa zosankhazi kumapeto, koma ubwino waukulu wa dongosolo lino ndi chiyani? Kungoyang'ana koyamba, izi zitha kuwoneka ngati zikuwonjezera kukakamiza kopangidwa ndi olankhula onse awiri. Koma ayi - inde, dongosolo loterolo lili ndi mphamvu zowirikiza kawiri (zimatengedwa ndi ma coils awiri, osati imodzi), koma ndi theka lamphamvu ("gawo" lachiwiri lamphamvu lomwe limaperekedwa kwa chowuzira chokweza chachiwiri silikuwonjezera kukakamiza) . Nanga n’cifukwa ciani timafunika mphamvu yosagwila nchito imeneyi? Kugwiritsa ntchito madalaivala awiri pamakina okankhira (composite, isobaric) kumapanga mtundu wa dalaivala m'modzi wokhala ndi magawo osiyanasiyana. Poganiza kuti ili ndi ma transducers awiri ofanana, Vas adzakhala ndi theka ndipo fs sadzawonjezeka, chifukwa timakhala ndi misa yogwedezeka kawiri; Qts sichikuchulukiranso, chifukwa tili ndi "drive" iwiri. Summa summarum, kugwiritsa ntchito kukankha-kukoka kumakupatsani mwayi wowonjezera kuchuluka kwa nduna (kachitidwe kambiri - kuphatikiza kutsekedwa, bass-reflex, bandpass, koma osati mizere yopatsira kapena nyanga kabati) kuti mupeze mawonekedwe, poyerekeza ndi kugwiritsa ntchito chowulira mawu chimodzi (o magawo omwewo, monga ndi zokuzira mawu zokhala ndi sitiroko ziwiri).
Chifukwa cha izi, ndi voliyumu yayikulu kwambiri (ndikukumbutsani kuti gawo lapamwamba limagwira magawo ena), ma frequency otsika kwambiri (-6 dB pa 20 Hz) adapezedwa.
