ʻO ka mea nui o ka microphone condenser, ʻo ia ke poʻo pole, i haku ʻia me ʻelua kiʻiʻoniʻoni metala;Ke hoʻoulu ʻia ka hawewe kani, ʻo ka ʻokoʻa ʻokoʻa o ka kiʻiʻoniʻoni metala ke kumu o ka capacitance ʻokoʻa a hoʻohua i kēia manawa.No ka mea pono ke poʻo pole i kekahi volta no ka polarization, pono maʻamau nā microphones condenser e hoʻohana i ka lako mana phantom e hana.Loaʻa i ka microphone condenser nā hiʻohiʻona o ka sensitivity kiʻekiʻe a me ke kuhikuhi kiʻekiʻe.No laila, hoʻohana maʻamau ia i nā mele ʻoihana like ʻole, nā kiʻiʻoniʻoni a me ka hoʻopaʻa kīwī, kahi mea maʻamau i ka hale hoʻopaʻa leo.
ʻO kekahi ʻano microphone condenser i kapa ʻia ʻo electret microphone.Loaʻa i ka microphone Electret nā hiʻohiʻona o ka leo liʻiliʻi, ka laulā ākea ākea, ka hilinaʻi kiʻekiʻe a me ke kumukūʻai haʻahaʻa.Ua hoʻohana nui ʻia i nā lako kamaʻilio, nā mea hana hale a me nā huahana uila ʻē aʻe.Ke hana ʻia nā microphones electret, ua hoʻokau ʻia ka diaphragm i ka mālama polarization kiʻekiʻe-voltage a hoʻopaʻa mau ʻia, no laila ʻaʻohe pono e hoʻohui i ka volta polarization hou.No ka portability a me nā koi ʻē aʻe, hiki ke hana liʻiliʻi liʻiliʻi i ka microphone condenser electret, no laila e hoʻopilikia i ka maikaʻi o ke kani i kekahi ʻano.Akā ma ka manaʻo, ʻaʻole pono e ʻokoʻa ka maikaʻi o ka leo ma waena o nā microphones electret o ka nui like a me nā microphones condenser kuʻuna i hoʻohana nui ʻia i nā studio hoʻopaʻa leo.
ʻO ka inoa Kina condenser microphone haole name condenser microphone alias condenser microphone principle he capacitor kiʻiʻoniʻoni i uhi ʻia i ke gula lahilahi he mau P farad kūʻē kūʻokoʻa G ohm pae hiʻohiʻona haʻahaʻa, liʻiliʻi a me ka naʻau kiʻekiʻe.

ʻO ke kumu hoʻopaʻa leo o ka microphone condenser, ʻo ia ka hoʻohana ʻana i kahi kiʻi ʻoniʻoni gula lahilahi loa e like me hoʻokahi pole o ka capacitor, i hoʻokaʻawale ʻia e kekahi mau hapaʻumi o ka millimeters, a me kahi electrode paʻa ʻē aʻe, i mea e hana ai i kahi capacitor o nā P farads.Hoʻololi ka electrode kiʻiʻoniʻoni i ka hiki o ka capacitor a hana i kahi hōʻailona uila ma muli o ka haʻalulu o ka hawewe kani.No ka mea, he mau P farads wale no ka capacitance, he kiʻekiʻe loa kona kūpaʻa kūloko, hiki i ke kiʻekiʻe o G ohms.No laila, pono kahi kaapuni e hoʻololi i ka impedance G ohm i kahi impedance maʻamau ma kahi o 600 ohm.ʻO kēia kaapuni, ʻike ʻia hoʻi ʻo "pre amplification circuit", i hoʻohui pinepine ʻia i loko o ka microphone condenser a pono i kahi "phantom power supply" e mana i ke kaapuni.Ma muli o ka noho ʻana o kēia kaapuni pre amplification, pono e hoʻoikaika ʻia nā microphones condenser e ka mana phantom e hana maʻamau.ʻO nā microphones condenser + phantom power supply ka mea maʻamau, ʻoi aku ka maʻalahi ma mua o nā microphones dynamic maʻamau.I nā huaʻōlelo ʻē aʻe, pono ka lako mana phantom no nā microphones condenser e hoʻopaʻa i ka hoʻohana ʻia ʻana ma nā kamepiula a i ʻole nā mea hana ʻē aʻe, a ʻaʻole e liʻiliʻi ke kani i hoʻopaʻa ʻia ma mua o nā microphones dynamic.[1]

ʻO kēia ʻano microphone ka mea maʻamau no ka mea maʻalahi, liʻiliʻi a maikaʻi.I kekahi manawa kapa ʻia ʻo ia ka microphone.ʻO ke kumumanaʻo kūikawā penei: ma kahi papa kūikawā o nā mea, aia kahi uku.ʻAʻole maʻalahi ka hoʻokuʻu ʻana ma aneʻi.Ke kamaʻilio ka poʻe, haʻalulu ke kiʻi i hoʻopaʻa ʻia.ʻO ka hopena, ke hoʻololi mau nei ka mamao ma waena o ia a me kekahi pā, e hopena i ka hoʻololi o ka capacitance.Eia kekahi, no ka mea, ʻaʻole i hoʻololi ʻia ka hoʻopiʻi ma luna, e hoʻololi ʻia ka volta e like me q = Cu, Ma kēia ala, ua hoʻololi ʻia ka hōʻailona leo i hōʻailona uila.Hoʻohui pinepine ʻia kēia hōʻailona uila i kahi FET i loko o ka microphone e hoʻonui i ka hōʻailona.I ka hoʻohui ʻana i ke kaapuni, e nānā pono i kona pili pono.Eia kekahi, hoʻohana pinepine ʻia nā microphones piezoelectric i kekahi mau mea haʻahaʻa haʻahaʻa.E like me ka mea i hōʻike ʻia ma ke Kiʻi 1.
ʻO ka mea nui o ka microphone condenser ʻo ia ke poʻo o ke kahua, i haku ʻia me ʻelua kiʻiʻoniʻoni metala;Ke hoʻoulu ʻia ka hawewe kani, ʻo ka ʻokoʻa ʻokoʻa o ka kiʻiʻoniʻoni metala ke kumu o ka capacitance ʻokoʻa a hoʻohua i kēia manawa.Pono nā microphones condenser 48V phantom power supply, microphone amplification equipment a mixer e hana.
ʻO ka microphone condenser kekahi o nā ʻano microphone kahiko loa, hiki ke huli ʻia i ka hoʻomaka ʻana o ke kenekulia 20.Ke hoʻohālikelike ʻia me nā ʻano microphones ʻē aʻe, ʻo ka ʻōnaehana mechanical o nā microphones condenser ka mea maʻalahi.ʻO ka mea maʻamau ka hoʻopili ʻana i kahi diaphragm conductive lahilahi ma kahi ʻāpana metala i kapa ʻia ʻo ka pā hope, a hoʻohana i kēia hana e hana i kahi capacitor maʻalahi.A laila e hoʻohana i kahi puna uila o waho (maʻa mau ka mana phantom, akā ʻo ka hapa nui o nā microphones condenser pū kekahi i kā lākou mana lako ponoʻī) e hāʻawi i ka mana i ka capacitor.Ke hana ka puʻe kani i ka diaphragm, e hana ka diaphragm i nā haʻalulu liʻiliʻi me ka nalu, a laila e hoʻololi kēia haʻalulu i ka uila puka ma o ka hoʻololi ʻana o ka capacitance, ʻo ia ka hōʻailona puka o ka microphone.ʻO ka ʻoiaʻiʻo, hiki ke hoʻokaʻawale ʻia nā capacitance Microphones i kekahi mau ʻano, akā like kā lākou kumu hana maʻamau.I kēia manawa, ʻo ka microphone condenser kaulana loa ʻo ia ka U87 i hana ʻia e Neumann.[2]

Hōʻike ʻia ke ʻano maʻamau o ka microphone condenser ma ke kiʻi "Principle of condenser microphone": ua māhele ʻia nā papa electrode ʻelua o ka capacitor i ʻelua ʻāpana, i kapa ʻia ʻo diaphragm a me back electrode.Aia ke poʻo poʻo microphone diaphragm hoʻokahi, ka diaphragm a me ka pou hope ma nā ʻaoʻao ʻelua, ʻelua poʻo diaphragm poʻo, poʻo hope ma waena, a aia ka diaphragm ma nā ʻaoʻao ʻelua.
Hoʻokō ʻia ke kuhikuhi ʻana o ka microphone condenser ma o ka hoʻolālā akahele a me ka debugging o ke ala acoustic ma ka ʻaoʻao ʻē aʻe o ka diaphragm, kahi hana nui i nā manawa hoʻopaʻa leo like ʻole, ʻoi aku ka hoʻopaʻa ʻana a me ke ola.
ʻO ka ʻōlelo maʻamau (me nā ʻokoʻa ʻē aʻe), ʻoi aku ka maikaʻi o nā microphones condenser ma mua o nā microphones dynamic i ka naʻau a me ka hoʻonui ʻana i ka pane kiʻekiʻe (i kekahi manawa haʻahaʻa).
Pili kēia i ke kumu hana e pono ai nā microphones condenser e hoʻololi i nā hōʻailona kani i kēia manawa mua.ʻO ka maʻamau, ʻoi aku ka lahilahi o ka diaphragm o nā microphones condenser, kahi maʻalahi e haʻalulu ma lalo o ka mana o ke kani kani, e hopena i ka hoʻololi like ʻana o ka volta ma waena o ka diaphragm a me ka hope hope o ka ʻāpana diaphragm.E hoʻonui ʻia kēia hoʻololi uila e ka preamplifier a laila hoʻololi ʻia i puka hōʻailona kani.
ʻOiaʻiʻo, ʻo ka preamplifier i ʻōlelo ʻia ma ʻaneʻi e pili ana i ka amplifier i kūkulu ʻia i loko o ka microphone, ma mua o ka "preamplifier", ʻo ia hoʻi, ka preamplifier ma ka mixer a i ʻole interface.Ma muli o ka liʻiliʻi loa o ka ʻāpana diaphragm o ka microphone condenser, paʻakikī loa ia i nā hōʻailona leo haʻahaʻa a i ʻole kiʻekiʻe.He oiaio.Hiki i ka hapa nui o nā microphones condenser ke hopu pololei i nā hōʻailona kani i hiki ʻole i nā poʻe he nui ke lohe.[2]

ʻO ka microphone condenser ka microphone maikaʻi loa no ka hoʻopaʻa ʻana.ʻO kāna hoʻohana ʻana me ka solo, saxophone, flute, steel pipe a woodwind, acoustic guitar a i ʻole acoustic bass.Ua kūpono ka microphone condenser no kēlā me kēia wahi e pono ai ke kani a me ke kani kiʻekiʻe.Ma muli o kona ʻano ʻino a me ka hiki ke mālama i ke kani kani kiʻekiʻe, ʻo nā microphones condenser ke koho maikaʻi loa no ka hoʻoikaika ʻana i ke kani ola a i ʻole ka hoʻopaʻa ola.Hiki iā ia ke kiʻi i ka pahu wāwae, ke kīkā a me ka ʻōlelo bass.[3]
