He aha kāu e ʻike ai i ke koho ʻana i nā leo kaʻa
Nā mea
ʻO ke koho ʻana i nā acoustics no ke kaʻa he mamao loa ia mai kahi hana maʻalahi, no ka mea, pono kēia i ka ʻike kumu o ke kumumanaʻo o ka leo kaʻa. Eia kekahi, i kēlā me kēia hihia, pono ʻoe i ka ʻike i ka hoʻonohonoho ʻana a me ka hoʻonohonoho ʻana i nā mea hana, no ka mea ma hope o ka hoʻonohonoho pono ʻole ʻana, hiki i ka mea nona ka acoustics ke hālāwai i nā ʻaoʻao, maikaʻi ʻole ke kani a me nā pilikia ʻē aʻe.
ʻO ke kūʻai ʻana i nā acoustics pipiʻi ʻaʻole ia he panacea no nā pilikia kani e hiki mai ana. Hiki ke hana piha i nā ʻōnaehana acoustic inā hoʻokomo ʻia lākou ma ka ʻoihana. No laila, hiki iā mākou ke hoʻoholo i ka hoʻonohonoho kūpono a me ka hoʻokomo ʻana o ka mea haʻiʻōlelo ʻoi aku ka nui ma mua o kona kumukūʻai. Ma kēia ʻatikala, e pane mākou i nā acoustics e koho ai, a me ka mea e nānā ai i ke kūʻai ʻana i nā ʻāpana acoustic.
ʻAno haʻiʻōlelo
I ka noʻonoʻo ʻana i ka ʻōnaehana leo e koho ai no ke kaʻa, pono ʻoe e noʻonoʻo mua i ke ʻano o nā ʻōlelo. Hoʻokaʻawale ʻia nā ʻōlelo a pau no nā ʻōnaehana leo i ʻelua mau ʻāpana - coaxial a me ka mea.
He aha ka coaxial acoustics
ʻO nā mea haʻiʻōlelo coaxial he mea haʻiʻōlelo, ʻo ia ka hoʻolālā ʻana o kekahi mau mea haʻiʻōlelo e hana hou ana i nā alapine like ʻole. Ma muli o ka crossover i kūkulu ʻia i loko o ka hoʻolālā ʻana o kēia ʻano o nā mea haʻiʻōlelo, ua māhele pinepine ʻia lākou i ʻelua ala ʻekolu ala, 4..5..6..etc. No ka ʻike ʻana i ka nui o nā pūʻulu i loko o nā mea haʻiʻōlelo coaxial, pono ʻoe e helu i nā mea ʻōlelo. Makemake mākou e hoʻolohe i ka ʻoiaʻiʻo ua lawa nā pūʻulu ʻekolu e hana hou i nā alapine kani āpau.
ʻO Acoustics nona nā pūʻulu 4 a ʻoi aʻe paha ke kani a ʻoluʻolu ʻole ke hoʻolohe iā ia. ʻO nā mea maikaʻi o ka coaxial acoustics ka maʻalahi o ka hoʻopaʻa ʻana a me ke kumu kūʻai haʻahaʻa.
He aha ke ʻano acoustics?
ʻO nā acoustics component nā mea haʻiʻōlelo o nā pae alapine like ʻole, aia i kahi kaʻawale. ʻO kēia mau mea haʻiʻōlelo ʻoihana no ke kani kiʻekiʻe. ʻO kēia ma muli o ka loaʻa ʻole o nā mea haʻi'ōlelo me nā alapine like ʻole ma kahi hoʻokahi.
No laila, hiki iā ʻoe ke loaʻa ka leʻaleʻa piha mai ka hoʻolohe ʻana i ke mele, ʻoiai ua hoʻokaʻawale ʻia ke kani i nā ʻāpana ʻokoʻa. Eia nō naʻe, pono ʻoe e uku no kēlā me kēia leʻaleʻa: ʻoi aku ka nui o nā mea haʻiʻōlelo ma mua o nā coaxial, a ʻo ka hoʻokomo ʻana i nā ʻāpana acoustics e pono ai ka hoʻoikaika ʻana.
Ka hoʻohālikelike o ka ʻāpana a me ka coaxial acoustics
ʻO ka maikaʻi o ka hana hou ʻana o ke kani, ke kumukūʻai a me ka maʻalahi o ka hoʻonohonoho ʻana, ʻaʻole nā mea āpau e hoʻokaʻawale i nā acoustics coaxial mai nā ʻāpana. ʻO kekahi ʻokoʻa koʻikoʻi ma waena o kēia mau ʻano ʻōlelo ʻelua ʻo ia ka wahi o ke kani i loko o ke kaʻa. ʻO nā hemahema o nā mea haʻiʻōlelo coaxial, ʻo ia ka mea i hana lākou i ke kani me ka haiki. ʻO nā mea haʻiʻōlelo o ka puka mua he mau mea ʻōlelo. ʻO nā alapine kiʻekiʻe, inā kuhikuhi ʻia lākou i nā wāwae, paʻakikī loa e lohe, mahalo i nā ʻāpana i hoʻokaʻawale ʻia, ua hoʻokomo ʻia nā tweeters kiʻekiʻe, no ka laʻana, ma ka dashboard o kahi kaʻa a kuhikuhi ʻia i ka mea hoʻolohe. No laila, piʻi pinepine ka kikoʻī o ke kani; hoʻomaka ke mele e pāʻani ʻaʻole mai lalo, akā mai ke alo, ʻike ʻia ka hopena i kapa ʻia ʻo ke kahua.
Mea hoʻoheheʻe a me ka mea hoʻokuʻu
Pono e loa'a ka 'ike e pili ana i ka mea i hana 'ia ai ka 'ike no nā leo kani. Hiki ke hoʻohana ʻia kēia mau mea no ka hana ʻana i nā diffusers: pepa, polypropylene, backstren, titanium, magnesium, aluminika, a pēlā aku.
ʻO ka mea maʻamau ka pepa diffuser. I ke kaʻina hana o kā lākou hana ʻana, paʻi ʻia nā pepa pepa, a laila hāʻawi ʻia lākou i kahi ʻano conical. Akā he mea kūpono ke ʻōlelo ʻia, ʻoiaʻiʻo, aneane hiki ke hoʻopili ʻia nā diffuser pepa āpau i ke ʻano composite, no ka mea, hoʻohana ʻia nā mea synthetic i ke kaʻina hana. ʻAʻole hōʻike nā mea hana koʻikoʻi i nā mea i hoʻohana ʻia, no ka mea, aia kēlā me kēia o lākou i kāna meaʻai ponoʻī.
- ʻO nā mea maikaʻi o nā cones pepa he kani kikoʻī, i hana ʻia ma muli o ka damping kūloko kiʻekiʻe. ʻO ka hemahema nui o nā cones pepa i manaʻo ʻia ʻo ko lākou ikaika haʻahaʻa, ʻo ia ka hopena o ka mana kani i ka ʻōnaehana leo.
- ʻO nā diffusers i hana ʻia me ka polypropylene he hoʻolālā paʻakikī. Hōʻike ʻia lākou e kahi leo kūlohelohe, a me nā hiʻohiʻona impulsive maikaʻi loa. I ka manawa like, ʻoi aku ka kūpaʻa o ia mau diffusers i ka mechanical a me ka lewa ma mua o nā diffusers pepa.
- Hoʻomaka ʻia nā diffusers i hana ʻia i ka titanium a me ka alumini ma Kelemania i nā makahiki 80. Hoʻokumu ʻia kā lākou hana ʻana i ka ʻenehana deposition vacuum. Hoʻokaʻawale ʻia nā Domes i hana ʻia i kēia mau mea e ka maikaʻi maikaʻi o ke kani: ʻo ke kani ke ʻike a maopopo.
I ka hopena, ma kēia ʻāpana, makemake wau e ʻōlelo ua aʻo nā mea hana i ka hana ʻana i nā acoustics maikaʻi mai kahi kokoke i nā mea āpau, aia kekahi mau mea haʻiʻōlelo i hana ʻia i nā metala hanohano, akā he nui ke kālā. Manaʻo mākou iā ʻoe e hoʻolohe i nā mea haʻiʻōlelo me kahi cone pepa, he kani maikaʻi loa ia, a ua hoʻāʻo ʻia e nā hanauna ʻoi aku ma mua o hoʻokahi.
A he mea pono nō hoʻi e hoʻolohe i ka mea i hana ʻia ai ka hoʻokuʻu ʻana o waho o ka diffuser. Hiki ke hana ʻia ka hoʻokuʻu ʻana i ka mea like me ka diffuser, a i ʻole he mea ʻokoʻa i ke ʻano o ke apo i hana ʻia i ka rubber, polyurethane a i ʻole nā mea ʻē aʻe. ʻO kekahi o nā mea kiʻekiʻe kiʻekiʻe a me ka maʻamau o ka hoʻokuʻu ʻia ʻana he rubber. Pono e noho laina laina ma luna o ka laula o ka neʻe ʻana o ka ʻōnaehana leo kani, a maʻalahi hoʻi no ka mea e pili ana kēia i ke alapine resonant.
ʻO kahi subwoofer ka mea haʻi'ōlelo like i hiki ke hana hou i nā alapine haʻahaʻa "He aha ka ʻokoʻa ma waena o kahi subwoofer passive a me kahi mea hana."
Ka mana a me ka naʻau o ka acoustics
Nui ka poʻe i makemake i ke koho ʻana i nā lekiō no ka lekiō kaʻa, akā ʻaʻole maopopo lākou i ka manaʻo o ka mana. Aia ka manaʻo kuhihewa ʻo ka nui o ka mana, ʻoi aku ka nui o ka leo e pāʻani ai. Eia naʻe, ma ka hoʻomaʻamaʻa ʻana, ʻike ʻia kahi mea haʻiʻōlelo me ka mana o 100 W e pāʻani mālie ma mua o ka mea haʻiʻōlelo me ka hapalua o ka mana. No laila, hiki iā mākou ke hoʻoholo i ka mana ʻaʻole ia he hōʻailona o ka leo kani, akā no ka hilinaʻi mechanical o ka ʻōnaehana.
ʻO ka leo o nā mea haʻiʻōlelo i kekahi ʻano pili i ko lākou mana, akā naʻe, ʻaʻole pili pono i kēia ʻāpana. Maikaʻi ka nānā ʻana i ka mana o ka ʻōnaehana leo i ka wā e kūʻai ai i nā acoustics no kahi amplifier. I kēia hihia, ʻo ka mana helu (RMS) wale nō ka mea nui, no ka mea, ʻaʻole e hāʻawi nā helu ʻē aʻe i ka ʻike pono i ka mea kūʻai aku a alakaʻi wale iā ia. Akā, ʻaʻole liʻiliʻi ka hana a RMS i kekahi manawa me ka ʻoiaʻiʻo, no laila, kūpono ke ʻōlelo ʻana he ʻike ʻole ka mana o ka mana no nā mea kūʻai aku.
He hoʻopunipuni ka nui o nā mea hoʻokani leo, no ka mea, loaʻa i nā ʻōnaehana leo nui nā neodymium magnets. ʻOiai ʻaʻole maikaʻi lākou i ka nānā ʻana, ʻoi aku ka kiʻekiʻe o kā lākou mau mea magnetic ma mua o nā mea magnet ferrite. Ma ka hoʻomaʻamaʻa ʻana, ʻoi aku ka ikaika o ka leo o ka mua.
ʻO ka Sensitivity kahi ʻāpana o nā ʻōnaehana leo e hōʻike ana i ka ikaika o ke kaomi kani. ʻOi aku ka kiʻekiʻe o ka naʻau, ʻoi aku ka nui o ke kani, akā inā hāʻawi ʻia nā mea ʻōlelo me ka mana i kuhikuhi ʻia. No ka laʻana, hiki i kahi mea haʻahaʻa haʻahaʻa i hui pū ʻia me kahi mea hoʻonui ikaika ke hoʻopuka i kahi leo ʻoi aʻe ma mua o kahi leo ʻike kiʻekiʻe. ʻO ka ʻāpana no ke ana ʻana i ka naʻau he decibel i puʻunaue ʻia e ka paepae o ka lohe (dB/W*m). Hoʻopili ʻia ka naʻau e nā ʻāpana e like me ke kaomi kani, ka mamao mai ke kumu, a me ka ikaika hōʻailona. Eia nō naʻe, pono e hoʻomaopopo ʻaʻole pono mau ke hilinaʻi i kēia ʻāpana, no ka mea, ke ana kekahi mau mea hana leo ʻōlelo i ka naʻau i nā kūlana maʻamau. ʻO ke kūpono, pono ke ana ʻia ka naʻau ma kahi mamao o hoʻokahi mika me ka hōʻailona o hoʻokahi watt.
Ke koho ʻana i nā mea haʻiʻōlelo i kāu kaʻa, e nīnau i ka mea kūʻai aku he aha ka naʻau o kēia ʻōlelo? ʻO ka haʻahaʻa haʻahaʻa ʻo 87-88 db, aʻo mākou iā ʻoe e koho i nā acoustics i loaʻa ka sensitivity o 90-93db.
E heluhelu pū i ka ʻatikala, "pehea e koho ai i ka amplifier kūpono no kāu ʻōnaehana leo."
ʻO Brand
ʻO kekahi ʻōlelo aʻoaʻo e hiki ke hāʻawi ʻia i ka poʻe e noʻonoʻo nei e koho i kahi mea hana kūikawā ʻaʻole e alualu i ke kumu kūʻai haʻahaʻa a e makaʻala i ke kūʻai ʻana i nā mea ʻōlelo mai nā mea hana kaulana ʻole. No ka hoʻowalewale ʻana i nā ʻōlelo a nā mea kūʻai aku, ʻaʻole pono ʻoe e hoʻolohe i kēia mau makana hoʻowalewale, no ka mea ʻoi aku ka maikaʻi o ka huli ʻana i nā mea hana i hoʻokumu lōʻihi iā lākou iho ma ka mākeke.
He mau ʻumi makahiki ko lākou ʻike i ka hana ʻana i nā mea ʻōlelo, hoʻomaikaʻi i ko lākou kaulana, a no laila e hana wale i nā huahana kiʻekiʻe.
ʻO ka pane i ka nīnau e pili ana i ke koho ʻana i nā acoustics no ke kaʻa ʻaʻole i maʻalahi e like me ka laʻana, he ʻumi makahiki i hala aku nei, no ka mea, aia ka nui o nā mea hana ma ka mākeke (ʻoi aku ma mua o 200). ʻO ka mana o nā ʻōnaehana acoustic Kina i paʻakikī loa i ka hana. Mai haʻalele loa i nā huahana Kina, no ka mea me kahi kālā paʻa, kūʻai aku i kahi ʻōnaehana leo mai Kina ʻaʻole ia he hoʻoholo maikaʻi ʻole. Akā ʻo ka pilikia, aia ka nui o nā mea kūʻai aku ʻole ma ka mākeke e hōʻike ana i nā ʻōnaehana leo i hana ʻia ma Kina ma ke ʻano he huahana branded mai nā mea hana ʻAmelika a ʻEulopa. I kēia hihia, ʻo ka mea kūʻai aku, nāna i hoʻoholo i ʻelua mau haneli rubles, e kūʻai aku i nā acoustics "branded" no $100, ke ʻoi aku kona kumukūʻai maoli ma mua o $30.
Inā mākou e noʻonoʻo i kahi ʻano kikoʻī o ke kani, a laila no ke kani kūlohelohe ʻoi aku ka maikaʻi e kūʻai i nā ʻōnaehana leo ʻEulopa (Morel, Magnat, Focal, Hertz, LightningAudio, JBL, DLS, BostonAcoustic, ʻaʻole kēia ka papa inoa holoʻokoʻa) . Manaʻo mākou e hōʻole ʻoe i ke kūʻai ʻana i nā ʻoihana e like me (Mystery, supra, Fusion, Sound max, calcel) He kumukūʻai hoʻohenehene kēia mau mea hana, akā kūpono ke ʻano leo o kēia mau mea leo. ʻO nā ʻōnaehana haʻi'ōlelo mai Sony, Pioneer, Panasonic, JVS, Kenwood kekahi mau koho maikaʻi loa, akā hoʻopiʻi kekahi o kā lākou mea nona ka maikaʻi o ke kani. Inā ʻoe e ʻimi nei i ka hui kūpono o nā ʻāpana like me ke kumukūʻai a me ka maikaʻi, a laila ʻoi aku ka maikaʻi e hoʻopili i nā mea hana i ʻōlelo ʻia ma luna.
Pehea e koho ai i nā leo wikiō maikaʻi mai Ural
hopena
Ua hoʻoikaika nui mākou i ka hana ʻana i kēia ʻatikala, e hoʻāʻo nei e kākau iā ia ma kahi ʻōlelo maʻalahi a hoʻomaopopo. Akā aia iā ʻoe ke hoʻoholo inā mākou i hana a ʻaʻole paha. Inā he mau nīnau kāu, e hana i kumuhana ma ka "Forum", e kūkākūkā mākou a me kā mākou kaiāulu aloha i nā kikoʻī āpau a loaʻa ka pane maikaʻi loa iā ia.
