Kupeza Galimoto Yabwino Yogulitsa
Pamene anthu ambiri amaganiza za magalimoto otsika galimoto, amaganiza za kugwedezeka kwa mafupa, dzino. Ndipo ngakhale kuti izo ndizogwirizana molondola, pali zambiri ku subwoofer kuposa kungoyendetsa mawindo mu galimoto iliyonse yomwe imakwera pafupi ndi iwe pa kuyima. Mkokomo wa phokoso lochepa ndilo gawo lalikulu la mtundu uliwonse wa nyimbo, kotero kuti zenizeni za phokoso lirilonse limagwirizana kwambiri ndi luso lake lakugunda zolemba zochepa ngati zapamwamba. Mitundu ina ya nyimbo idzapindula ndi gawo lalikulu kwambiri kuposa ena, koma kuwonjezera pazitsulo zina zabwino zingabweretse moyo wa stereo iliyonse.
Kaya mukuganiza zowonjezera subwoofer kwa wokhazikika wokamba galimoto kapena kuyang'ana pa kumanga chinthu kuchokera pansi, pali zifukwa zofunika zomwe muyenera kuziganizira. Zina mwa zinthu zofunika kwambiri kuziwona ndizo:
- kukula kwa subwoofer
- mtundu wamkati
- mphamvu
- kukhudzidwa
- mphepo
Kukula kwa subwoofer kumafunikira
Kukula kwa chigawochi ndi chimodzi mwa zifukwa zazikulu zomwe zimapangitsa kuti zikhale zazikulu komanso zotsika. Monga lamulo lonse la thumb, pulogalamu yayikulu imabweretsa zinthu zabwino, choncho khalani ndi malingaliro pamene mukuyang'ana malo abwino. Malo amakhalanso okhudzidwa mu kayendedwe ka kayendedwe ka magalimoto, komabe ndikofunikira kuti mutengepo musanayambe kugula. Ngati mukuyang'ana mabasi amphamvu omwe mungapeze, ndiye kuti mukufuna kupita ku malo akuluakulu omwe angagwirizane ndi malo omwe alipo.
Kumangirira Phokoso Pang'ono Pokha
Ngakhale kukula kwa gawoli ndi kofunikira, mtundu wa malo omwe mumasankha ungakhale ndi zotsatira zazikulu kwambiri. Chipindacho, chomwe nthawi zambiri chimatchedwa bokosi, ndi chimodzimodzi: bokosi lomwe liri ndi subwoofer. Mitundu itatu yayikulu yazitseko ndi:
- losindikizidwa
- kutumizidwa
- bandpass
Ngati mukufuna mabasi omwe ali ozama komanso osamveka ngati gawo lanu likufalikira , ndiye kuti muyenera kupita kumalo osindikizidwa. Nthaŵi zina, kachigawo kakang'ono m'bwalo labwino, losindikizidwa lidzabweretsa mabedi ozama kusiyana ndi chigawo chachikulu pamatsegulidwe. Malo oterewa ndi abwino kwambiri, otsika bwino omwe sangagwedezezeza kukhuta kwanu.
Malo otsekedwa ndi ma bandpass amapereka zitsulo zosakhala zakuya. Komanso, amaperekanso mawu ambiri. Ngati mumvetsera nyimbo zomwe zimafuna mabomba okwera kwambiri, ndipo simusamala zonse zokhudzana ndi kulondola, ndiye mukufuna kuyang'ana chimodzi mwazitsulozi.
Njira ina ndi kusankha subwoofer yomwe yapangidwa kuti ikhale yopanda ntchito. Izi zowonjezereka zimakonzedwa ku bolodi lomwe laikidwa mkati mwa thunthu. Thunthu palokha liyenera kukhala lopanda mpweya chifukwa limakhala ngati lozungulira.
Mavuto a Mphamvu, Chisamaliro, Kuthamanga ndi Kutengeka
Ngakhale kukula kwa subwoofer ndi mtundu wazitseko ndizofunikira, zizindikiro zomwe mukufunikira kumvetsera ndizofunika kwa RMS, SPL, range frequency, ndi ohms. Mphamvu ya mphamvu imatanthawuza mphamvu zogwiritsira ntchito mphamvu, ndipamwamba mtengo wa RMS umatanthauza zambiri. Chofunika kwambiri cha RMS ndi chopanda phindu popanda chilichonse cholimbitsa, komabe ndikofunika kukhala ndi mutu umodzi kapena amplifier yomwe ikugwirizana (kapena makamaka kuposa) RMS ya gawolo.
Kumvetsetsa, komwe kumayesedwa ngati nambala yachitsulo (SPL), imatanthawuza kuchuluka kwa mphamvu yomwe gawoli likufunikira kuti likhale ndi buku lopatsidwa. Kulembera komwe kuli ndipamwamba za SPL sizikufuna mphamvu zochulukirapo kutulutsa mavoti apamwamba monga subs omwe ali ndi mawerengedwe otsika a SPL. Izi zikutanthauza kuti mukufuna gawo lokhala ndi chidziwitso chapamwamba ngati anu amphamvu kapena mutu uli pansi.
Mafupipafupi amamveka phokoso lamtundu umene gawolo likhoza kutulutsa, kotero inu mukufuna kuyang'ana chigawo pamapeto otsika a msinkhu. Komabe, phokoso lenileni limene mumachokera ku gawo lanu lidalira kwambiri mtundu wa malo omwe mumasankha. Popeza kuti pakhomolo likhoza kumveka phokoso limene limamveka pamakutu anu, mawerengedwe afupipafupi a gawoli sangathe kusonyeza bwino lomwe ntchito yake yeniyeni.
Kuti mupindule kwambiri ndi amp and sub, ndifunikanso kufanana ndi impedance . Chiwerengerochi chikuwonetsedwa mu ma ohms, ndipo chimatanthawuza kukaniza kwa magetsi kwa gawoli. Kuchita zinthu mwachisawawa kumakhala kosavuta, koma kungakhale kovuta malinga ndi momwe gawoli liwongolera, kapena ngati liri ndi mawu ambiri.
