Kuphunzira kuwerengera voliyumu ndi doko la gawo la inverter subwoofer box
Zamkatimu
Nthawi zambiri, okonda nyimbo zabwino zamagalimoto amakhala ndi funso: momwe mungawerengere bokosi la subwoofer kuti lizigwira ntchito ndi kubweza kwapamwamba kwambiri? Mutha kugwiritsa ntchito malingaliro kuchokera kwa opanga subwoofer. Komabe, iwo sangakhale okwanira kuti akwaniritse zotsatira zabwino kwambiri.
Chowonadi ndi chakuti opanga samaganizira za malo oyika bokosilo, komanso kalembedwe ka nyimbo zomwe zikuimbidwa. Panthawi imodzimodziyo, khalidwe la mawu lingakhale lovomerezeka. Koma komabe, zidzatheka "kugwedeza" subwoofer momwe mungathere pongoganizira za makina ndi kalembedwe ka nyimbo zomwe zikuseweredwa. Chifukwa chake kufunikira kwa kuwerengera kwa munthu payekha pabokosi la subwoofer pamutu uliwonse.
Pali mapulogalamu ambiri apadera omwe apangidwa kuti athandize kuthetsa vutoli. Odziwika kwambiri ndi JBL SpeakerShop. Ngakhale JBL yatulutsa pulogalamuyo kwa nthawi yayitali kwambiri, ikupitilizabe kufunidwa kwambiri pakati pa omwe amapanga ma subwoofers awo. Nthawi yomweyo, amangosewera bwino "subs". Kuti adziwe magwiridwe antchito onse a pulogalamuyi, woyambitsa angafunike nthawi. Ngakhale kuti ndi yaying'ono, ili ndi ma graph ambiri, minda ndi zina zomwe muyenera kuzimvetsa bwino.
Zomwe muyenera kudziwa musanayike JBL SpeakerShop?
Pulogalamuyi yowerengera ya subwoofer imatha kukhazikitsidwa pakompyuta ya Windows yokha. Tsoka ilo, idatulutsidwa kalekale, motero imagwirizana ndi matembenuzidwe a XP ndi pansipa. Kuti muyike pamitundu ina yamtsogolo (Windows 7, 8, 10), mudzafunika emulator yapadera yomwe imakulolani kutsanzira XP.
Pakati pa otchuka kwambiri, komanso nthawi yomweyo mapulogalamu aulere omwe amakulolani kutsanzira mawindo akale a Windows, akuphatikiza Oracle Virtual Box. Ndi yosavuta komanso yomveka. Pokhapokha ndi izi, ndipo mutatha kuchita zoyeserera, mutha kukhazikitsa pulogalamu ya JBL SpeakerShop.

Momwe mungagwiritsire ntchito ndi JBL SpeakerShop?
Ntchito yonse ya pulogalamuyi imagawidwa m'ma module awiri akuluakulu. Pogwiritsa ntchito yoyamba, mutha kuwerengera kuchuluka kwa bokosi la subwoofer. Yachiwiri imagwiritsidwa ntchito powerengera crossover. Kuti muyambe kuwerengera, muyenera kutsegula SpeakerShop Enclosure Module. Imatha kutsanzira kuyankha pafupipafupi kwa mabokosi otsekedwa, zotsekera za bass-reflex, ma bandpasses, komanso ma radiator osagwira ntchito. Pochita, njira ziwiri zoyambirira zimagwiritsidwa ntchito nthawi zambiri. Kuchuluka kwa magawo olowetsamo kungakhale kosokoneza. Komabe, musataye mtima.
Kuti muwerengere kusamukako, ndikwanira kugwiritsa ntchito magawo atatu okha:
- pafupipafupi (Fs);
- voliyumu yofanana (Vas);
- Total Quality factor (Qts).
Kuwongolera kulondola kwa kuwerengera, ndikololedwa kugwiritsa ntchito mawonekedwe ena. Izi zitha kupezeka m'mabuku olankhula kapena pa intaneti. Komabe, monga tafotokozera pamwambapa, mutha kupitilirabe ndi magawo atatu awa, otchedwa magawo a Thiel-Smol. Mutha kuyika magawo awa m'mawonekedwe omwe amawonekera mutakanikiza makiyi a Ctrl + Z. Kuphatikiza apo, mutha kupita ku fomuyo mutasankha chinthucho menyu Loudspeaker - Parametersminimum. Pambuyo polowa deta, pulogalamuyi idzakupangitsani kuti muwatsimikizire. Pa siteji yotsatira, m'pofunika kutsanzira khalidwe la matalikidwe-pafupipafupi, ndiye - kuyankha pafupipafupi.
Timawerengera gawo la inverter nyumba
Poyamba, tidzasonyeza chitsanzo cha kuwerengera gawo inverter nyumba. Mu gawo la Vented Box, sankhani Mwambo. Kukanikiza batani la Optimum kumadzaza magawo onse. Koma mu nkhani iyi, kuwerengera adzakhala kutali ndithu. Kuti mudziwe zambiri, ndi bwino kuyika deta pamanja. M'munda wa Vb, muyenera kufotokoza pafupifupi voliyumu ya bokosilo, ndi Fb, zoikamo.
Kuchuluka kwa bokosi ndi kukhazikitsa
Ziyenera kumveka kuti malowa amasankhidwa malinga ndi mtundu wa nyimbo zomwe zidzayimbidwe nthawi zambiri. Panyimbo zokhala ndi ma frequency otsika kwambiri, gawoli limasankhidwa mkati mwa 30-35 Hz. Ndikoyenera kumvera hip-hop, R'n'B, etc. Kwa okonda nyimbo za rock, trance ndi nyimbo zina zotsika kwambiri, izi ziyenera kukhazikitsidwa kuyambira 40 ndi kupitilira apo. Kwa okonda nyimbo omwe amamvetsera mitundu yosiyanasiyana, njira yabwino kwambiri ingakhale kusankha ma frequency apakati.
Posankha kukula kwa voliyumu, munthu ayenera kupitilira kukula kwa wokamba nkhani. Chifukwa chake, wokamba 12-inch amafunikira bokosi la bass-reflex ndi voliyumu "yoyera" pafupifupi malita 47-78. (onani nkhani yokhudza mabokosi). Pulogalamuyi imakulolani kuti mulowe mobwerezabwereza mipangidwe yosiyanasiyana, kenako dinani Kuvomereza, ndiyeno Plot. Pambuyo pa izi, ma graph oyankha pafupipafupi a wokamba nkhani omwe amaikidwa m'mabokosi osiyanasiyana adzawonekera.
Posankha ma voliyumu ndi makonda, mutha kubwera pazophatikizira zomwe mukufuna. Njira yabwino kwambiri ndi mayendedwe afupipafupi, omwe amafanana ndi phiri lofatsa. Nthawi yomweyo, iyenera kukwera mpaka 6 dB. Pasakhale zokwera ndi zotsika. Pamwamba pa phiri lolingalira liyenera kukhala m'dera la mtengo womwe wasonyezedwa m'munda wa Fb (35-40 Hz, pamwamba pa 40 Hz, etc.).
Musaiwale kuti powerengera subwoofer yagalimoto, ndikofunikira kuphatikiza ntchito yosinthira ya chipinda chokwera.
Pankhaniyi, munthu ayenera kuganizira za kukwera kwa "magulu otsika" chifukwa cha kuchuluka kwa kanyumba. Mutha kuyatsa izi poyang'ana bokosi lomwe lili pafupi ndi chithunzi chagalimoto chaching'ono chomwe chili pamwamba kumanja kwa graph.
Kuwerengera Volume ya Port
Pambuyo pofanizira mayendedwe oyankha pafupipafupi, zimangokhala kuwerengera doko. Izi zitha kuchitika pogwiritsa ntchito menyu Box-Vent. Komanso, zenera limatha kutsegulidwa mukakanikiza Ctrl + V. Kuti mulowetse deta, sankhani Mwambo. Pa doko lozungulira, sankhani Diameter, ndi doko lolowera, sankhani Dera. Tiyerekeze kuti mukufuna kuwerengera malo olowera doko.
Pankhaniyi, muyenera kuchulukitsa kuchuluka kwa bokosi ndi 3-3,5 (pafupifupi). Ndi bokosi "loyera" la malita 55, 165 cm2 (55 * 3 = 165) imapezeka. Nambala iyi iyenera kulowetsedwa m'munda wofananira, pambuyo pake kuwerengera kwakutali kwa doko kudzachitika.
Pa izi, kuwerengera kumawerengedwa kuti kwatha! Komabe, ndi bwino kukumbukira kuti pulogalamuyi imawerengera voliyumu ya "net". Mutha kudziwa kuchuluka kwa voliyumu powonjezera kuchuluka kwa doko ndi khoma lake kumtengo "woyera". Kuwonjezera pamenepo, muyenera kuwonjezera mawu omveka kuti agwirizane ndi wokamba nkhaniyo, ndipo mutapeza mfundo zofunika, mungayambe kukonzekera chojambulacho. Itha kuwonetsedwa ngakhale papepala losavuta, ngakhale kudzera pamapulogalamu a 3D. Popanga ndizofunika
ganizirani makulidwe a khoma la bokosilo. Anthu odziwa bwino amalangiza kuwerengera koteroko ngakhale wokamba nkhani asanagulidwe. Izi zikuthandizani kuti mupange ndendende subwoofer yomwe ingakwaniritse zopempha zonse.
Mwina bokosi lanu lili m'nkhokwe yathu ya zojambula zomalizidwa.
