1. He ʻokoʻa ka loina kani
a.Condenser microphone: Ma muli o ke kumu o ka capacitive charge a me ka hoʻokuʻu ʻana ma waena o nā conductors, me ka hoʻohana ʻana i ka metala ultra-thin a i ʻole ke kiʻi ʻoniʻoni gula-plated e like me ke kiʻi ʻoniʻoni e hoʻoulu i ke kani kani, i mea e hoʻololi ai i ka volta static ma waena o nā conductors, e hoʻohuli pololei iā ia i ka ikehu uila. hōʻailona, a loaʻa i ka impedance pukana kūpono a me ka hoʻolālā naʻau ma o ka hoʻopili ʻana i ka uila.
b.Dynamic microphone: hana ʻia ia me ke kumu o ka induction electromagnetic.Hoʻohana ʻia ka coil e ʻoki i ka laina induction magnetic ma ke kahua magnetic e hoʻololi i ka hōʻailona kani i ka hōʻailona uila.
2. Nā hopena kani like ʻole
a.Condenser microphone: hiki i ka microphone condenser ke hoʻololi pololei i ke kani i hōʻailona ikehu uila ma o ka hilinaʻi wale ʻana i ka ʻenehana hana mīkini pololei, akā i hui pū ʻia me nā kaapuni uila paʻakikī.Loaʻa iā ia nā hiʻohiʻona kiʻekiʻe loa mai ka lani mai, no laila ua lilo ia i koho maikaʻi loa no ka ʻimi ʻana i ka hoʻopio kani kumu.
b.Dynamic microphone: ʻaʻole maikaʻi kona pane transient a me nā hiʻohiʻona kiʻekiʻe e like me ka mea o ka microphone capacitive.ʻO ka maʻamau, he haʻahaʻa haʻahaʻa ka leo microphones, ʻaʻohe lako mana, hoʻohana maʻalahi, hana paʻa a hilinaʻi.
