Loudspeakers - kūkulu a me nā palena

ʻO ka ʻōnaehana kani maʻalahi ʻelua mau mea nui, nā leo kani a me nā mea hoʻonui. Ma ka ʻatikala ma luna, e aʻo hou ʻoe e pili ana i ka mea mua a me ka mea āu e hoʻolohe ai i ke kūʻai ʻana i kā mākou leo ​​hou.

Building

Aia kēlā me kēia leo leo i kahi hale, nā leo leo a me kahi crossover.

ʻO ka hale, e like me kāu e ʻike ai, ʻike mau ʻia ʻo ia ka home o nā mea haʻiʻōlelo. Hoʻolālā kūikawā ʻia no kahi transducer kikoʻī, no laila inā makemake ʻoe e hoʻololi i nā mea ʻōlelo me nā mea ʻē aʻe i hana ʻia ai ka hale, pono ʻoe e noʻonoʻo i ka nalowale o ka maikaʻi o ke kani. E pōʻino paha ka leo kani ponoʻī i ka wā e hana ai ma muli o nā ʻāpana hale kūpono ʻole.

He mea koʻikoʻi nō hoʻi ka hoʻololi ʻana i ka leo kani. ʻO ka hana o ke keʻa ka hoʻokaʻawale ʻana i ka hōʻailona e hiki ana i ka leo kani i loko o nā pūʻulu haiki, a laila hoʻopuka ʻia kēlā me kēia me kahi leo leo kūpono. No ka mea ʻaʻole hiki i ka hapa nui o nā mea haʻiʻōlelo ke hoʻopuka hou i ka laulā piha, pono ka hoʻohana ʻana i kahi crossover. Loaʻa i kekahi mau ʻōlelo crossovers kahi ʻōpuʻu kukui i hoʻohana ʻia e pale i ka tweeter mai ke ahi.

Nā ʻano kolamu

ʻEkolu ʻano kolamu ka mea maʻamau:

• nā leo leo piha piha

• nā ukali

• nā leo kani bass.

ʻO ke ʻano o ka leo kani e pono ai mākou e hilinaʻi loa i ka mea a mākou e hoʻohana ai i kā mākou ʻōnaehana kani.

Hoʻohana ʻia ka kolamu bass, e like me ka inoa, e hana hou i nā alapine haʻahaʻa, ʻoiai hoʻohana ʻia ka satellite e hana hou i ke koena o ka hui. No ke aha la ka mahele ana? ʻO ka mea mua, i ʻole e "luhi" i nā satelite me ka nui o nā alapine haʻahaʻa. I kēia hihia, hoʻohana ʻia kahi crossover ikaika e puʻunaue i ka hōʻailona.

ʻO ka pahu kani piha, e like me ka inoa e hōʻike nei, e hoʻopuka hou i ka laulā holoʻokoʻa o ka bandwidth. Hoʻohana pinepine ʻia kēia hopena i nā hanana liʻiliʻi, kahi ʻaʻole pono mākou i ka leo kiʻekiʻe a me ka nui o nā alapine haʻahaʻa. Hiki i ia kolamu ke lawelawe ma ke ʻano he satellite. Hoʻokumu pinepine ʻia ma kahi tweeter, midrange a me woofer (maʻamau 15 ”), ʻo ia hoʻi kahi hoʻolālā ʻekolu ala.

Aia kekahi mau hana ʻelua, akā ʻoi aku ka nui o ke kumukūʻai (akā ʻaʻole i nā manawa a pau), no ka mea ma kahi o ka tweeter a me ka midrange driver, loaʻa iā mākou kahi mea hoʻokele kahua.

No laila he aha ka ʻokoʻa ma waena o kahi mea hoʻokele a me kahi tweeter? Hiki iā ia ke pāʻani ma kahi ākea ākea o nā alapine.

ʻO nā tweeters kaulana loa me kahi crossover i koho pono ʻia hiki ke pāʻani maikaʻi mai ke alapine o 4000 Hz, ʻoiai hiki i ka mea hoʻokele ke pāʻani mai kahi alapine haʻahaʻa loa, ʻo 1000 Hz i ka hihia o nā mea hoʻokele kiʻekiʻe. No laila he mau mea liʻiliʻi mākou i ka crossover a ʻoi aku ka maikaʻi o ke kani, akā ʻaʻole pono mākou e hoʻohana i kahi mea hoʻokele midrange.

Inā mākou e ʻimi nei i nā kolamu no nā hanana liʻiliʻi, pili pono, hiki iā mākou ke hoʻāʻo e koho i kahi kūkulu ʻekolu ala. ʻO ka hopena, he haʻahaʻa haʻahaʻa loa ia no ka mea ua hoʻohana ʻia ka mea holoʻokoʻa e hoʻokahi mana amplifier a ʻaʻole pono mākou i kahi crossover e hoʻokaʻawale i ka hui e like me ke ʻano o ka satellite a me ka woofer, no ka mea, ua hoʻolālā ʻia kēlā ʻōlelo. i kūkulu ʻia i loko o ka passive crossover.

Eia naʻe, inā mākou e hoʻolālā e hoʻonui i nā mea hana i nā pae me ka manaʻo e hāʻawi i ke kani i nā hanana nui a i ʻole mākou e ʻimi nei i kahi hoʻonohonoho o nā ana liʻiliʻi, pono mākou e ʻimi i nā satelite kahi e pono ai mākou e koho i nā woofers hou (bass). Eia nō naʻe, ʻoi aku ka maikaʻi o kēia hopena, akā ʻoi aku ka maikaʻi o ka hapa, no ka mea, hoʻohana ʻia ka mea holoʻokoʻa e ʻelua a ʻoi aku ka mana amplifiers (e pili ana i ka nui o ke kani) a ua māhele ʻia ka māhele alapine ma waena o ka satellite a me ka bass e kahi kānana uila, a i ʻole. keʻaʻa.

No ke aha i ʻoi aku ka maikaʻi o kahi crossover ma mua o kahi crossover passive kuʻuna? ʻAe nā kānana uila i nā pali o ka pali ma ke kiʻekiʻe o 24 dB / ʻOkakopa a ʻoi aku, ʻoiai ma ke ʻano o nā crossovers passive, loaʻa iā mākou ka 6, 12, 18 dB / oct. He aha ke ʻano o kēia ma ka hana? Pono ʻoe e hoʻomanaʻo ʻaʻole he "koʻi" nā kānana a ʻaʻole e ʻoki pono i ke alapine crossover i ka crossover. ʻOi aku ka nui o ka slope, ʻoi aku ka maikaʻi o kēia mau alapine "ʻoki", e hāʻawi iā mākou i kahi leo maikaʻi aʻe a hiki i nā hoʻoponopono liʻiliʻi i ka manawa like e hoʻomaikaʻi ai i ka linearity o ka laina alapine emitted.

ʻO ke kuʻekuʻe kiʻekiʻe passive ke kumu i nā hanana makemake ʻole a me ka piʻi ʻana o ke kumukūʻai o ke kūkulu ʻana i ke kolamu (ʻoi aku ka maikaʻi o nā coils a me nā capacitors), a paʻakikī hoʻi e hoʻokō mai ka ʻike loea.

Nā ʻāpana kolamu

Hōʻike ka ʻāpana hoʻonohonoho i nā waiwai o ke kolamu. Pono mua mākou e hoʻolohe iā lākou i ke kūʻai ʻana. ʻAʻole pono e ʻōlelo, ʻaʻole ka mana ka mea nui loa. Pono ka huahana maikaʻi e wehewehe pono i nā ʻāpana me nā kūlana ana pololei.

Aia ma lalo kahi pūʻulu o nā ʻikepili maʻamau e ʻike ʻia ma ka wehewehe huahana:

• Libra

• Mana sinusoidal / Nominal / RMS / AES (AES = RMS) i hōʻike ʻia ma Watts [W]

• Efficiency, a i ʻole Efficiency, SPL (hāʻawi ʻia me ke ana kūpono, e laʻa me 1W / 1M) i hōʻike ʻia ma nā decibels [dB]

• ʻO ka pane alapine, i hōʻike ʻia ma hertz [Hz], hāʻawi ʻia no nā hāʻule o ka alapine (eg -3 dB, -10dB).

E hoʻomaha iki kākou ma ʻaneʻi. ʻO ka maʻamau, i ka wehewehe ʻana i nā leo leo maikaʻi ʻole, hāʻawi ka mea hana i ka pane pinepine o 20-20000 Hz. Ma waho aʻe o ke alapine e pane ai ka pepeiao o ke kanaka, ʻoiaʻiʻo, he haʻahaʻa haʻahaʻa loa ka 20 Hz. ʻAʻole hiki ke loaʻa i nā lako hana, ʻoi aku ka semi-professional. Hoʻokani ʻia ka mea haʻiʻōlelo bass maʻamau mai 40 Hz me ka emi ʻana o -3db. ʻO ke kiʻekiʻe o ka papa o nā mea hana, ʻoi aku ka haʻahaʻa o ke alapine o ka mea haʻiʻōlelo.

• Impedance, hōʻike ʻia ma ohms (maʻamau 4 a i ʻole 8 ohms)

• Nā mea haʻiʻōlelo i hoʻohana ʻia (ʻo ia hoʻi nā mea haʻiʻōlelo i hoʻohana ʻia ma ke kolamu)

• Noi, kumu nui o ka lako

Loaʻa

ʻAʻole maʻalahi ke koho ʻana i ka leo a maʻalahi ke hana hewa. Eia hou, paʻakikī ke kūʻai ʻana i nā leo leo maikaʻi e ka nui o nā lako haʻahaʻa haʻahaʻa i loaʻa ma ka mākeke.

Ma kā mākou hale kūʻai e ʻike ai ʻoe i nā manaʻo hoihoi. Aia ma lalo ka papa inoa o nā hōʻailona i makemake ʻia e pono ke nānā aku. Eia kekahi, e hoʻolohe i nā mea hana o ka hana Polish, ʻoi aku ka maikaʻi o ka manaʻo maʻamau, akā i ka hoʻohālikelike pololei ʻana, ʻoi aku ka maikaʻi e like me ka hapa nui o nā hoʻolālā haole.

Aia ma lalo kahi papa inoa o nā ʻōlelo aʻoaʻo kūpono, a he mea kūpono hoʻi e nānā pono i ka pale ʻana iā ʻoe iho mai ke kūʻai ʻana i kahi ʻōnaehana kani maikaʻi ʻole:

• Ka helu o nā leo leo i loko o ke kolamu – he nui nā tweeters i nā hale hana kānalua – piezoelectric, i kekahi manawa ʻokoʻa. Pono e loaʻa i kahi leo kani maikaʻi i hoʻokahi tweeter / mea hoʻokele

• Ka mana nui (hiki ke ʻōlelo ʻia ʻaʻole hiki i kahi leo kani liʻiliʻi, e ʻōlelo ʻo 8 ”, ʻaʻole hiki ke lawe i ka mana kiʻekiʻe loa o 1000W.

• Ua kūpono ka leo leo 15 ″ no ka hoʻolālā ʻekolu ala, a i ʻole no ka hoʻolālā ʻelua ala i hui pū ʻia me kahi mea hoʻokele ikaika (e hoʻolohe i ka ʻikepili o ka mea hoʻokele). I ka hihia o kahi hoʻolālā ʻelua ʻaoʻao, pono ʻoe i kahi mea hoʻokele ikaika, ma ka liʻiliʻi me kahi puka 2 ". He kiʻekiʻe nā kumukūʻai o ia mea hoʻokele, no laila ke kiʻekiʻe ke kumukūʻai o ka mea haʻiʻōlelo. Hōʻike ʻia ia mau pūʻolo e kahi leo contoured, kahi treble hoʻokiʻekiʻe a me kahi band haʻahaʻa, haʻalele i ka midrange.

• Ka nui touting e ka mea kūʻai aku - he maikaʻi huahana pale aku ia ia iho, he mea pono no hoi e imi i hou manaʻo ma ka Internet.

• Nā hiʻohiʻona ʻokoʻa (nā kala ʻālohilohi, nā kukui hou a me nā mea pono like ʻole). Pono pono nā mea hana, ʻike ʻole. Makemake mākou i ke kani a me ka hilinaʻi, ʻaʻole nā ​​hiʻohiʻona a me nā kukui. Pono e hoʻomaopopo ʻia, ʻo ka pūʻolo no ka hoʻohana ʻana i ka lehulehu ke nānā aku i ka nani.

• ʻAʻohe grilles a i ʻole kekahi ʻano pale no nā mea haʻiʻōlelo. E hoʻohana ʻia nā mea hana, no laila pono e pale maikaʻi ʻia nā leo kani.

• ʻO ka hoʻokuʻu ʻia ʻana o ka lāʻau lapaʻau ma ka leo kani = haʻahaʻa haʻahaʻa. Hoʻohana ʻia nā mea ʻōlelo hoʻomaha palupalu no ka home a i ʻole ka leo kaʻa. Hoʻohana ʻia nā mea haʻiʻōlelo paʻa paʻa wale i nā lako kahua.
