Homemade subwoofer: hana kino

Ua hoʻoholo ihola e hana i ko lakou mau subwoofer. Oe ua i ka woofer, a ua koho au i ka pono i loko o ka hale kūʻai. Where e hoʻomaka? Here mākou nānā i mea ole ma ka lolouila kaapuni, a paʻi wale i kekahi hapa, 'o ia hoʻi, ka mea maoli subwoofer ia iho: he hale noho me ka hōʻeuʻeu poo.

Ma waho aʻeo ia maikaʻi 'ōlelo no ka pono nui uila nā'ōlelo, nui no ka pono e huli i ka buke o ka pahu horn'ōnaehana a me kekahi mau ike i na intricacies o kona manufacturing. Homemade subwoofer e ia i ka e pono ai ka nui o ka pahu. E keia'ōnaehana i loko o ke kaʻa a me ka hale-i subwoofer no ka home, e pono ai ke kino - na mea nui ke keʻena e loli ai i ka leo e like ai.

E hoomanao i keia a pau leo mākou. He nalu. Mākou pepeiao ke kia oscillations me ke alapine (frequency) i loko o ka laulā, mai kekahi mau na umi i ka hola 20 tausani Hertz (pōʻaiapuni no kekona). Kēia huahelu ua manaoia e e kani nalu, ma ka mea ka mea, 'o ka apana uuku na lehulehu. He aha mākou e i lohe no ka mea, o ka loa haʻahaʻa alapine (frequency) - ka infrasound, a me ka mea kiekie oia ka alapine, a me mākou nō e audible - ultrasound (hoolohe mai i kana mau holoholona, e like me nā'īlio). Sound nalu hoʻopulapula wale i loko me ka lawa nuʻa ka kaiapuni. Mākou e lohe ai i ke kaniʻana, no ka mea, mākou i loko o ia he 'ia (ea).

Ke subwoofer reproduces loa haʻahaʻa nä alapine mai ai i kekahi mau haneri Hertz. He walaʻau nō nalu ua hana ma ka neʻeʻana o ka diffuser pelane (ape diaphragm horn). Kona neʻe 'ua hoololiia a hiki i ka lewa, a me ke kani akaka ia mākou e lohe. I ka hopena o kekahi mea i 'ano like me ka hana ana o ka EII ni.

O ka papa kuhikuhi hana o ka subwoofer pa - kiʻi i ka maikaʻi kani. Luna Hoomalu me ka pahu mea e hiki ia oe, no ka mea, no ka mea muli o ke kiʻekiʻe-kbps kani nalu mākou i kekahi wale pae o ka mea pono, a me ka lehulehu horn e hāʻawi mai iā mākou wale elua: maikaʻi a me ka io (mua a me ka hopeʻaoʻao o ka diffuser membranes). Ua huli mai i ka ai-kapaia acoustic pōkole kaapuni ka loa kaʻawaʻawa loa i ka pepeiao. E hookaawale i kekahi leo, mai kekahi pae a me ka lawelawe 'ana me ka pahu horn.

Homemade poʻomanaʻo, i keʻano o? Ieoaeunoaa iauaeoia. Ka loa, he pono ole - me kekahi horn huli mai, e like me ia ma kaʻike mau kolamu, akā, ma laila nō oi luna 'manaʻo.

E like me oe i ike, ma ka mea e hookaawale i ka leo pae (i kokoke ai i kekahi o ia mau mea i loko o ka subwoofer), ka mea pono i ka rigidity nui no ke kino iho, aole ia e hoʻolele kuekueni i loko o ka lewa. No laila, Radio ka mea e like ai o ka mea a Mānoa ano nui i. Ma mua o ka mea mea ikaika, ka paʻakikī i, i ka maikaʻi o ka hopena.

E hoomanao i ka meaʻino koho no kekahi subwoofer - symmetrical manao. I hookuu, ke'ōlelo ua 'oni iki aku, mai ka waena. No hoi i paipai homemade subwoofer i loko o ka palapala o ke kupa, na aoao elua e hoano e ma ka nui. A pau keia ua hana e pale aku resonance.

Homemade subwoofer E i lawa na ka leo. Inā ka mea, ua nalowale, alaila, i ka haʻahaʻa-alapine kani ua noticeably hoʻonāwaliwaliʻia ma muli o ka ikaika puʻe i loko o ka pahu, a ua hana ma ka hana o kaʻili lahilahi. Inā 'oe e pono ai i ka hale-i subwoofer uuku ka leo, a laila, e pono e lawe i ka woofer me ka liʻiliʻi anawaena, no ka mea, ka paipaiʻia ka leo o ka pahu hilinaʻi nui ma ka nui o konaʻohana.

I ka papaʻaina helu pū 'ia ka paipai Ana.

Akā, ia mea maikaʻi, e nīnau aku i ka palapala kuhikuhi no kouʻano.
