He aha ka ke oki-i alapine (frequency) o ka subwoofer, a pehea e pono kele

Hoʻonohonohoʻia kēia kani amplifying i hoʻomākaukauʻia, e pili ana hoopuni iho kani paipai ooieoeiiaeuiiai kaʻawaleʻana kaha. Oia i nā leo'ōnaehana ka loaʻa o ke alo a me ka hope o 'ōlelo, he kikowaena Kanal a me ka subwoofer.

I ka la mahope lawelawe 'ana i ka hana hou kani' ole ma ka haʻahaʻa alapine huahelu mai ka 20 a hiki i 180 Herz. ka wā e kiai ana wikiō papahana a me Film i pihaʻi, e hoohuli o ka Naita me ia holo nōhie ua hoʻohana 'ia i kēia koho, OOOXO o ka makahiki rockets, a like wahi, i hiki ai i kou makemake, e ka heluʻaiʻanaʻelemakule lawa e hoohaalulu ai i ka lewa.

Nō kāu, subwoofers papahana no kaʻeleu rula, i mea, i kā lākou mau kukulu-ma ka pahu hoʻonui leo, mana lako a me ka hoʻoponopono. Ka pakiko, a palapala koho loaʻa nā papa i lawelawe, " 'ilikai» (Level) a me ka "cutoff alapine (frequency)» (Crossover Frequency). Paha 'ilikai i lawelawe, mea maopopo, keia hooponopono pinepine' kani. A i ka ke kumu o ka lua o ka hoʻonohonohoʻia, ka mea i ike ole a pau.

Like ka hoʻoleleʻenehana 'ōlelo, subwoofer ua kaupalena ia e na luna kapa o ke alapine (frequency) laulā. I ka huli, e māheleʻia basses i hohonu - 40 Hz, meakino - mai i ka 80 Hz, a me ke kiʻekiʻe - mai i 160 Hz. No a ka cutoff alapine ua kau, o ka hohonu i ma ka acoustic hopena hilinaʻi nui. Ma kekahi mau hihia, komo i loko o ka laulā kiʻekiʻe o ka nui uila i ka mea softer kani, no kekahi laʻana, ka wā e hoolohe i ka mele a kiai kiʻiʻoniʻoni me kūikawā 'ole i ua hou. Inā, eia nae, pono i ka oi stringent ia ma luna o ka'emi'ōnaehana o ka Mea Nānā, no ka mea hoike, i loko o ka palapala o ka crumbling hale, a exploding kŘhele, ka subwoofer oki-aku alapine (frequency) hiki ke 'oni iki pilina e infradiapazonu.

Technically, ka luna alapine kali - na mea hana. O ka holo ana ma ke kālaikūlohea ka mea, ua ike ia i ka 'auhau o ka Kānana i ka waiwai me ka mahalo i ka haʻahaʻa nä alapine a me inductance - i kiʻekiʻe. Penei, he mea LC-Kānana ke kuleʻa kaʻawale i ka makemake 'āpana huahelu, oiai e hoemi i ka nui o undesired neaiaea pae. E "malama mai" kiʻekiʻe a me ka meakino alapine (frequency) o nā manaʻo kōkua i ka subwoofer, ia mea lawa paha kana e ho'ā laua OAaEeOO maʻi o ka liʻiliʻi mea pihana - he mau pF. Akā, ua he primitive Kānana e emiʻoi aku ko lākou ala apuupuu alapine (frequency) pane, no laila, i loko o ka hana pono i ko lakou manao hou huikau.

A, i ka cutoff alapine ua hoakaka ia a me ke kānana o ka auoiaea neaiaea e hele ana i ka ikaika loa loudspeaker. E hana i kēia ma loko o ke kino kokoke i ka'ōlelo o kekahi papa me capacitors a me inductors.

Ke cutoff alapine (frequency) o ka LPF (haʻahaʻa e hele Kānana) maikaʻi loa e e like, koe ma ka haʻahaʻa-kāki nenoai ole ia kuleana pili i ia.

Pololei subwoofer okoʻa no ka manawa i pili i nā acoustic eiiiiiaiou o ka hale keaka'ōnaehana - ka mea pono ke ahonui a me ka thoroughness. A hooponopono maikai ua manaoia, ma i ka nui uila kinoea mai ka alo, a hoopuni iho 'ōlelo i inā e infra-haʻahaʻa nä alapine broadcasted ia ia, me ka ole "hoʻopaʻapaʻa" me kekahi i kekahi, i mea ikaika. I ka rula o "ka ikaika nui ka maikaʻi" 'Aʻole e hana' aneʻi.

Pela, ke cutoff alapine mea nui ka 'okoʻa no ia e hōʻoiaʻiʻo pololei a me ka pahuhopu nei hana o ka nohona ma Hawaiʻi nei.
