Uyini umehluko phakathi kwe-subwoofer esebenzayo kanye ne-passive subwoofer?
Okuqukethwe
Ungathola injabulo ephelele yokulalela umculo uma imoto inama-acoustics ekhwalithi ephezulu ene-subwoofer enamandla. Nokho, abashayeli abaningi abakwazi ukunquma ukuthi bathenge i-subwoofer esebenzayo noma engenzi lutho. Ukuze sinqume umehluko phakathi kwalezi zinhlobo ezimbili, ake sibheke okungaphansi kokwenziwa kanye nokusebenzayo ngokuhlukana, bese siqhathanisa.
Yini ezoshintsha uma ufaka i-subwoofer emotweni?
Ama-acoustics emoto avamile, ahlanganisa izipikha ze-broadband, anokwehla kwebanga eliphansi lefrikhwensi. Lokhu kuthinta kakhulu ikhwalithi yokukhiqizwa kabusha kwezinsimbi ze-bass namazwi.
Njengoba imiphumela yokuhlolwa ibonisa, uma kuqhathaniswa umsindo we-acoustics yemoto kanye nangaphandle kwe-subwoofer, ochwepheshe abaningi bakhetha inketho yokuqala, ngisho noma izikhulumi ezijwayelekile zisezingeni eliphezulu ngokwanele.
Ukuze uthole ulwazi olwengeziwe, funda isihloko esithi "Iziphi izici okufanele uzibheke lapho ukhetha i-subwoofer emotweni"
Ibanga Lempendulo Yemvamisa
Ibanga lamafrikhwensi aphindaphindekayo lincike kukho kokubili ukwakheka kwesikhulisazwi nasezicini zesipika ngokwaso. Umkhawulo ongaphezulu webhendi yokudlala ngokuvamile ungaphakathi kuka-120-200 Hz, ophansi ongu-20-45 Hz. Izici zokudlulisa zama-acoustics ajwayelekile kanye ne-subwoofer kufanele zidlulelane kancane ukuze kugwenywe ukucwiliswa kumkhawulokudonsa wokudlala ophelele.
Ama-subwoofers asebenzayo
I-subwoofer esebenzayo iyisistimu yesipika ehlanganisa i-amplifier eyakhelwe ngaphakathi, isipikha se-subwoofer, nebhokisi. Abanikazi abaningi bathenga lolu hlobo lwe-subwoofer ngenxa yokuzimela kwayo, ngoba ihlanganisa amadivaysi amaningana ngesikhathi esisodwa futhi ayidingi ukuthengwa kweminye imishini eyengeziwe. Ngaphezu kwalokho, i-subwoofer esebenzayo ibonakala ngokuthembeka nokuqina ngenxa yomklamo wayo olinganiselayo.
Yiqiniso, ukuhlanganisa okuyinhloko nokunesibindi kwama-subwoofers asebenzayo yizindleko zabo eziphansi. Awudingi ukufunda ithiyori yomsindo wemoto mayelana nokuthi iyiphi i-amplifier ongayikhetha nokuthi yiziphi izintambo ezidingekayo kule nqwaba. Uthenga ikhithi edingekayo, enakho konke ukufakwa, okuyi-subwoofer esivele ine-amplifier eyakhelwe ngaphakathi, kanye nesethi yezintambo zokuxhuma.
Konke kubonakala kuhamba kahle, kodwa lapho kukhona ukuhlanganisa okugqamile, kuba khona ukususa ngokugqamile. Lolu hlobo lwe-subwoofer lwenziwa ezingxenyeni eziningi zesabelomali, okungukuthi isikhulumi se-subwoofer sibuthakathaka kakhulu, i-amplifier eyakhelwe ngaphakathi ithengiswa kusuka ezingxenyeni ezishibhile, izintambo ezifakwe ku-kit zishiya okuningi okufanele zifiswe, ibhokisi le-subwoofer nalo lenziwe. wezinto ezincane ezingabizi.
Kukho konke lokhu kulandela ukuthi le subwoofer ayikwazi nje ukuba nekhwalithi yomsindo enhle futhi enamandla. Kodwa ngenxa yentengo yayo nokulula (okuthengiwe, okufakiwe), abathandi abaningi bomsindo wemoto ye-novice bashiya ukukhetha kwabo ku-subwoofer esebenzayo.
I-Passive subwoofer
- I-subwoofer ye-cabinet passive isipikha nebhokisi eselivele linikezwe umenzi. Kulabo abazibuza ukuthi iyini i-passive subwoofer, kubalulekile ukwazi ukuthi ayizi ne-amplifier, ngakho-ke ukuze usebenze ngokugcwele i-subwoofer engenzi lutho, uzodinga futhi ukuthenga i-amplifier kanye nesethi yezintambo zokuxhuma. yona. Okwenza le nqwaba ibize kakhulu kunokuthenga i-subwoofer esebenzayo. Kodwa lawa ma-subwoofers anenani lezinzuzo, njengomthetho, i-subwoofer ye-passive inamandla amaningi, umsindo olinganiselayo. Ungathenga i-amplifier yamashaneli angu-4 futhi ungaxhumani ne-subwoofer kuphela, kodwa futhi nezipikha ezimbili.
- Inketho elandelayo ye-subwoofer ye-passive ukuthenga isipikha se-subwoofer, njengoba usuqonda kakade, ukuze sidlale, ngeke udinge ukuthenga kuphela i-amplifier nezintambo, kodwa futhi udinga ukusenzela ibhokisi, noma ujike. kochwepheshe ukuze bathole usizo. I-subwoofer ngayinye idlala ngendlela yayo, ayixhomekile okwamanje kusuka kusipika, kodwa futhi nebhokisi. Emincintiswaneni yomsindo wemoto, ama-subwoofers asetshenziswa, lapho amabhokisi enziwa ngesandla noma uku-oda. Lapho uklama ibhokisi, kucatshangelwa ama-nuances amaningi. Okokuqala, yimuphi umzimba wemoto (uma uthatha i-subwoofer ku-sedan bese uyihlela kabusha enqoleni yesiteshi, izodlala ngokuhlukile) okwesibili, ukhetha luphi uhlobo lomculo (i-subwoofer tuning frequency) okwesithathu, hlobo luni lwe-amplifier nesipika unayo (ingabe unayo indawo yokugcina amandla). Lolu hlobo lwe-subwoofer lunomsindo ongcono kakhulu, ukugcinwa kwamandla amakhulu, amabhesi asheshayo ngaphandle kokulibala.
Ukuqhathanisa
Ake sibone ukuthi zisho ukuthini izinzuzo nezingozi zezinhlobo ezingenhla zama-subwoofers, nokuthi zingaqhathaniswa kanjani.
Akunakwenzeka ukusho ngokuqinisekile ukuthi yikuphi okungcono: i-subwoofer esebenzayo noma engenzi lutho. Konke lapha kungomuntu ngamunye. Uma ufuna ukusetha nokukhetha imishini yakho, khona-ke indlela engcono kakhulu kungaba ukuthenga i-subwoofer engenzi lutho. Uma ufuna ukwethemba umenzi futhi ufake umkhiqizo owenziwe ngomumo emotweni ongadingi ukutshalwa kwezimali okukhulu kwezimali, khona-ke kulokhu uhlobo olusebenzayo lufaneleka kakhulu kuwe.
I-subwoofer esebenzayo idume kakhulu kubashayeli bezimoto ngoba isivele ineamplifier eyakhelwe ngaphakathi futhi iza nezintambo zokuxhuma. Kodwa uma une-amplifier ehlukile, noma ufuna ukufeza i-bass enamandla kakhulu nekhwalithi ephezulu, kungcono ukunaka i-subwoofer engenzi lutho. Kodwa uma lokhu kungenele kuwe, ungathola ukudideka nakakhulu futhi uthole umphumela omuhle kakhulu ngokuthenga isikhulumi se-subwoofer bese usenzela ibhokisi, inani elikhulu lezindatshana lizonikela kulolu daba, ngaleyo ndlela lisize abaqalayo abakhethe lokhu. indlela enzima. Ngingathanda futhi ukuqeda izinganekwane zokuthi ukuxhuma i-subwoofer esebenzayo ne-passive kuhlukile ngobunkimbinkimbi. Eqinisweni, umdwebo wezintambo lapho ucishe ufane. Ukuze uthole ulwazi olwengeziwe, bheka isihloko esithi "indlela yokuxhuma i-subwoofer"
Yiziphi izipikha ezi-4 ze-subwoofer ezikwaziyo (ividiyo)
Sithemba ukuthi lesi sihloko sisizile ukuqonda ukuthi i-subwoofer esebenzayo ihluke kanjani kwe-passive. Linganisa i-athikili esikalini samaphoyinti angu-5. Uma uneminye imibono, iziphakamiso, noma wazi okuthile okungabaliwe kulesi sihloko, sicela usazise! Shiya ukuphawula kwakho ngezansi. Lokhu kuzosiza ukwenza ulwazi olukusayithi lube usizo nakakhulu.
isiphetho
Senze umzamo omkhulu ekwakheni lesi sihloko, sizama ukusibhala ngolimi olulula noluqondakalayo. Kodwa kukuwe ukuthi sikwenzile noma cha. Uma usenemibuzo, dala isihloko "kuforamu", thina nomphakathi wethu onobungane sizoxoxa ngayo yonke imininingwane futhi sithole impendulo engcono kakhulu kuyo.
