ʻO kahi membrane haʻalulu daimana a me kāna ʻano hana, e hoʻoili ana i kahi ikehu like ʻole (e like me ke kaula pale wela, plasma, lapalapa) e hoʻonāukiuki i ke kinoea hoʻokaʻawale ma luna o kahi ʻōmole, me ka hoʻohana ʻana i ka mamao ma waena o ka ʻili piʻo o ka ʻōmole a me ka ikehu like ʻole e hoʻonāukiuki i ke kinoea hoʻokaʻawale. Hoʻokumu nā ʻokoʻa i nā hopena hoʻomehana like ʻole. Ke uhi ʻia ka mea daimana ma luna o ka ʻili o ka ʻōmole, ʻokoʻa ka ulu ʻana o ka mea daimana, no laila he mau ʻano haʻalulu like ʻole ka kiʻiʻoniʻoni haʻalulu daimana, no laila he bandwidth leo ākea ka kiʻiʻoniʻoni haʻalulu daimana.
I ke koho ʻana i ka mea o ka diaphragm, ʻo nā mea nui e noʻonoʻo ai ʻo ia ka paʻakikī a me nā ʻano damping. ʻO ka paʻakikī ke kumu o ka alapine kūlohelohe o ka mea, a ʻo ke alapine kūlohelohe o ka mea me ka paʻakikī kiʻekiʻe he kiʻekiʻe loa ia, a ʻo ka hope, ʻo ke alapine kūlohelohe o ka mea me ka paʻakikī haʻahaʻa he haʻahaʻa hoʻi. Hiki i nā mea me nā ʻano damping maikaʻi ke hoʻolilo i ka membrane haʻalulu i kahi pane haʻalulu ʻoi aku ka maʻalahi, e hoʻolilo ana i ka pae kaomi leo puka o ka membrane haʻalulu i ʻoi aku ka maʻalahi.
ʻO nā mea membrane haʻalulu maʻamau e komo pū me ka pepa, nā mea polymer plastic, nā metala (Be, Ti, Al), nā keramika, a pēlā aku. He maikaʻi nā ʻano damping o nā mea pepa a me nā polymer, akā ʻaʻole lawa ka paʻakikī a me ka maʻalahi o ka hōʻino ʻana, a ʻaʻole lawa ka paʻakikī haʻahaʻa e hana ai iā lākou. Ua kaupalena ʻia ka alapine hana kiʻekiʻe loa. ʻOiai ʻoi aku ka paʻakikī o ka ʻili haʻalulu metala, he pipiʻi a paʻakikī hoʻi ke hana ʻana i nā metala paʻakikī e like me Be, Ti, a pēlā aku. Loaʻa i nā mea seramika ka pilikia o nā kaʻina hana sintering paʻakikī. Ma muli o nā waiwai mechanical maikaʻi loa a me ka ikaika o ka mea daimana, kūpono ia no ka hana ʻana i nā diaphragms māmā, paʻakikī kiʻekiʻe, a hiki ke hoʻohana ʻia i nā mea ʻōlelo waena a me ke alapine kiʻekiʻe. Hoʻopuka ʻia ke kani i makemake ʻia ma o ke alapine haʻalulu o ka diaphragm. ʻO ke kiʻekiʻe o ke alapine haʻalulu o ka diaphragm, ʻoi aku ka paʻakikī o ka ikaika mechanical a me nā koi maikaʻi o ka diaphragm, a hiki i ka hoʻohana ʻana i nā mea daimana e hana i ka diaphragm ke hoʻokō i kēia pahuhopu.
Ma ke ʻano laulā, aia ka palena kiʻekiʻe o ka alapine pane o ka membrane haʻalulu. Eia naʻe, me ka nānā ʻole inā hana ʻia ka membrane haʻalulu me ka daimana a i ʻole nā mea ʻē aʻe, ua kaupalena ʻia ke alapine kūlohelohe i kahi laulā kikoʻī ma muli o nā waiwai like o ka mea holoʻokoʻa, kahi e kaupalena ai i kāna hana bandwidth. ʻAʻole hiki ke hoʻololi ʻia nā ʻano damping a me ka paʻakikī, kahi e kaupalena ai i kona maikaʻi o ke kani a me ka hana timbre. No laila, inā makemake ʻoe e uhi i ka laulā alapine i ʻae ʻia e ka pepeiao kanaka, pono ʻoe e hoʻonohonoho i nā diaphragms he nui me nā bandwidths like ʻole a me nā palena kiʻekiʻe o ke alapine i ka manawa like e hoʻokō ai i ka hopena kani maikaʻi loa. No laila, ma ke ʻano mua, aia kahi ʻenehana o ka hoʻohana ʻana i nā mea like ʻole e hana i ka membrane haʻalulu i nā ʻāpana. Hana ʻia ka ʻāpana waena o ka membrane haʻalulu i kahi mea me ka paʻakikī kiʻekiʻe, a hana ʻia ke apo waho i kahi mea me ka paʻakikī haʻahaʻa. A laila hoʻohui ʻia kēia mau ʻāpana ʻelua e hana i hoʻokahi. Loaʻa i ka membrane haʻalulu ʻelua mau paʻakikī a me nā mānoanoa like ʻole i ka manawa like, a hiki ke uhi i kahi bandwidth nui aʻe. Eia naʻe, ʻo ka mānoanoa o ke kiʻiʻoniʻoni haʻalulu he lahilahi loa ia, a he paʻakikī ka hana hoʻohui. Inā e hoʻopili ʻia i nā mea daimana, he pilikia nui loa kāna ʻenehana hoʻopili a me ka mea hoʻopili, no laila ʻaʻole maʻalahi ke hoʻopili i nā mea daimana.
I mea e hoʻoponopono ai i nā pilikia i luna, ua hāpai kēia mea i hana ʻia i kahi kiʻiʻoniʻoni haʻalulu daimana a me kāna ʻano hana, hiki ke hoʻololi i ka paʻakikī, ka mānoanoa a me nā ʻano damping o nā wahi like ʻole ma ka kiʻiʻoniʻoni haʻalulu daimana, i loaʻa iā ia nā ʻano haʻalulu like ʻole a uhi i kahi alapine nui. .
Wahi a ka membrane haʻalulu daimana a me kāna ʻano hana i hōʻike ʻia ma kēia mea i hana ʻia, ua hoʻolako ʻia kahi ʻōmole me kahi ʻili piʻo, a ʻo kahi ikehu non-homogeneous (non-homogeneous) e hoʻonāukiuki i kahi kinoea i hoʻokaʻawale ʻia e hele ana ma luna o ka ʻōmole e hana i ka mahana kiʻekiʻe e hoʻomehana i ka ʻōmole i hōʻike ʻia ai ka ʻili o ka ʻōmole i kahi hoʻolaha mahana like ʻole.
Eia kekahi laʻana me
1. ʻO ke kaula kū'ē wela ke kikowaena (ka wahi ikehu kiʻekiʻe loa), a ʻo ka nui o ka mea hana e hōʻike ana i kahi hoʻolaha apo like ʻole.
2. Ma muli o nā hopena o ka nalu lōʻihi, ka amplitude, a me nā nalu kū ma ka plasma i hoʻonāukiuki ʻia e ka ikehu alapine kiʻekiʻe, hōʻike ka nui o nā mea pane i kahi ʻano poepoe me ka hoʻolaha like ʻole.
3. Holo ka ikehu lapalapa i waho mai ka wahi kikowaena, a hōʻike ka nui o nā mea hana i kahi hoʻolaha like ʻole.
ʻO ka mahana a me ka nui o ka hopena i hana ʻia e ka ikehu i luna nei e pala koke i waho ma ke kaʻina; no laila, pili nā kūlana ʻili mold like ʻole me nā wahi like ʻole o ka hopena o ka hopena e ulu ai nā kiʻiʻoniʻoni daimana me nā kūlana kūkulu like ʻole a me nā mānoanoa like ʻole, e hana ana i ka mea daimana he ʻano like ʻole. (ʻaʻole homogeneous) nā ʻano haʻalulu, e like me ka mānoanoa a i ʻole ka paʻakikī e hōʻike nei i ka hoʻolaha like ʻole, a laila wehe ʻia ka ʻiliʻili lahilahi daimana mai ka ʻōmole e hana i ka ʻili haʻalulu daimana. ʻO nā kūlana kūkulu o nā mea daimana e komo pū me ka micro-crystal (Micro-crystal), nano-crystal (Nano-crystal) a pēlā aku.
Wahi a ke kiʻiʻoniʻoni haʻalulu daimana i hana ʻia e kēia mea i hana ʻia, ʻaʻole like kona paʻakikī a me kona mānoanoa, a kiʻekiʻe ka paʻakikī o ka wahi waena, haʻahaʻa ka paʻakikī o ka ʻaoʻao, a nui ka mānoanoa o ka ʻaoʻao waena, a liʻiliʻi ka mānoanoa o ka ʻaoʻao. Hoʻopilikia ʻia nā ʻano haʻalulu o kēlā me kēia ʻāpana e ka paʻakikī a me ka hopena o ka mānoanoa he mau alapine kūlohelohe like ʻole, i hiki ai i ka diaphragm daimana ke loaʻa kahi bandwidth nui aʻe.
