ʻO kahi membrane vibrating daimana a me kāna ʻano hana hana, e hele ana i ka ikehu like ʻole (e like me ke uea pale wela, ka plasma, ka lapalapa) e hoʻonāukiuki i ke kinoea i hoʻokaʻawale ʻia ma luna o kahi mole, me ka hoʻohana ʻana i ka mamao ma waena o ka ʻili curved o ka mold a me ka ikehu like ʻole. e hoʻonāuki i ke kinoea dissociated Nā ʻokoʻa e hana i nā hopena hoʻomehana ʻokoʻa.Ke uhi ʻia ka mea daimana ma ka ʻili o ka mold, ʻokoʻa ka ulu ʻana o ka mea daimana, i loaʻa i ke kiʻi ʻoniʻoni daimana nā hiʻohiʻona non-homogeneous vibration, i ʻoi aku ka nui o ka bandwidth vibration o ka daimana vibration.
Ke koho ʻana i ka mea o ka diaphragm, ʻo ka mea nui e noʻonoʻo ai he paʻakikī a me nā hiʻohiʻona damping.Hoʻoholo ka paʻakikī i ke alapine maoli o ka mea, a ʻo ke alapine maoli o ka mea me ka paʻakikī kiʻekiʻe ke kiʻekiʻe, a ʻo ke ʻano hoʻi, ʻo ke alapine maoli o ka mea me ka paʻakikī haʻahaʻa.Hiki i nā mea me nā hiʻohiʻona hoʻoheheʻe maikaʻi ke hoʻolilo i ka membrane vibrating i ka pane haʻalulu maʻalahi, e hoʻomaʻamaʻa i ke kiʻekiʻe o ke kaomi kani o ka membrane vibrating.
Kuʻuna maʻamau vibrating membrane mea pepa, polymer plastic mea, metala (Be, Ti, Al), ceramics, etc. Pepa a me ka polymer mea i maikai damping hiʻona, akā, ilihune rigidity a me ka oluolu poino, a me ka haʻahaʻa paʻakikī 'aʻole lawa e hana ia lakou. Ua kaupalena ʻia ke alapine hana kiʻekiʻe.ʻOiai ʻoi aku ka paʻakikī o ke kiʻi ʻoniʻoni metala, ʻoi aku ka paʻakikī o nā metala paʻakikī e like me Be, Ti, etc.Loaʻa i nā mea seramika ka pilikia o nā kaʻina hana sintering paʻakikī.Ma muli o nāʻano mechanical maikaʻi a me ka ikaika o ka mea daimana, ua kūpono ia no ka hanaʻana i nā diaphragms māmā, kiʻekiʻe-rigidity, a hiki ke hoʻohanaʻia i waena o nā mea leo kiʻekiʻe.Hoʻokumu ʻia ka leo i makemake ʻia ma o ke alapine vibration o ka diaphragm.ʻO ke kiʻekiʻe o ka vibration frequency o ka diaphragm, ʻoi aku ka ikaika o ka ikaika mechanical a me nā koi o ka diaphragm, a me ka hoʻohana ʻana i nā mea daimana e hana i ka diaphragm hiki ke hoʻokō i kēia pahuhopu.
ʻO ka ʻōlelo maʻamau, ʻo ka membrane vibrating ka palena kiʻekiʻe o ke alapine pane.Eia nō naʻe, inā paha i hana ʻia ka membrane vibrating me ke daimana a i ʻole nā mea ʻē aʻe, ua kaupalena ʻia ke alapine kūlohelohe i kahi kikoʻī ma muli o nā ʻano mea waiwai holoʻokoʻa, e kaupalena ana i kāna hana bandwidth.ʻAʻole hiki ke hoʻololi wale ʻia nā hiʻohiʻona damping a me ka rigidity, e kaupalena ana i kona ʻano kani a me ka hana timbre.No laila, inā makemake ʻoe e uhi i ke alapine e ʻae ʻia i ka pepeiao o ke kanaka, pono ʻoe e hoʻonohonoho i nā diaphragms he nui me nā bandwidth like ʻole a me nā palena kiʻekiʻe pinepine i ka manawa like e loaʻa ai ka hopena kani maikaʻi loa.No laila, i ka hana mua, aia kahi ʻenehana o ka hoʻohana ʻana i nā mea like ʻole e hana i ka membrane vibrating i nā ʻāpana.ʻO ke kikowaena o ka membrane vibrating i hanaʻia i kahi mea me ka paʻakikī kiʻekiʻe, aʻo ke apo o waho i hanaʻia me kahi mea me ka paʻakikī haʻahaʻa.A laila hoʻohui ʻia kēia mau ʻāpana ʻelua e hana i hoʻokahi ʻO ka membrane vibrating ʻelua mau mea paʻakikī a me nā mānoanoa i ka manawa like, a hiki ke uhi i kahi bandwidth nui.Eia nō naʻe, ʻoi aku ka lahilahi o ka mānoanoa o ke kiʻi haʻalulu, a paʻakikī ka hana hoʻohui.Inā e hoʻohana ʻia i nā mea daimana, ʻo kāna ʻenehana hoʻopaʻa ʻana a me ka mea hoʻopili paʻa he pilikia nui loa, no laila ʻaʻole maʻalahi ka hoʻopili ʻana i nā mea daimana.
