He mau -wave ceramic resonator kānana kēia, me nā alapine waena o 455kHz a me 465kHz. I kēia manawa, e wāwahi mākou i kekahi o lākou a e ʻimi hohonu i loko o kona ʻano i loko. Ke hana nei mākou i kēia no ke kumu ʻē aʻe ma mua o ka ʻike.
Hōʻike ʻia ʻo Teardown
Ma hope o ka ʻili pono ʻana i kekahi ʻaoʻao o ka resonator me nā pihi diagonal, hiki iā mākou ke ʻike i kāna hana o loko.
Ke hoʻomau nei mākou i kā mākou ʻimi ʻana, ʻike mākou i ka -papa lehulehu i loko o ka resonator. ʻO ka ʻili ʻana i ka uhi plastik, loaʻa iā mākou kahi ʻike hohonu, e hōʻike ana i ke ʻano alakaʻi i loko. Ma ka nānā pono ʻana, ʻike ʻia nā electrodes metala ma luna a me lalo, a me kahi ʻano papalua -maalea i hoʻolālā ʻia i waenakonu. ʻO ka wehe hou ʻana e hōʻike i nā ʻāpana koʻikoʻi ʻekolu o ka resonator: ʻekolu mau electrodes, i māhele ʻia i ʻelua hapa, ma ka hema, a me ka piezoelectric ceramic i waenakonu. ʻO kēia piezoelectric ceramic, me kāna mau electrodes i loko a me waho, hana i kahi ʻōnaehana pale me ka pahu conductive ma lalo, e hōʻoia i ka pilina maʻalahi ma waena o ka piezoelectric ceramic a me nā electrodes metala.
He paʻakikī ke ʻano o loko o ka piezoelectric ceramic, ʻoiaʻiʻo he ʻekolu mau electrodes: ʻelua ma kekahi ʻaoʻao a hoʻokahi wale nō ma kekahi ʻaoʻao. Hoʻokomo maikaʻi ʻia ka ʻōpala conductive ma nā ʻili o kēia mau electrodes ʻelua, e hāʻawi ana i ka conductivity uila maikaʻi loa. Ma ka hoʻohui ʻana i nā electrodes ʻelua ma ka ceramic piezoelectric i nā pine o waho, ua hōʻoia ʻia kahi pilina paʻa me nā electrodes metala, e hana ana i kahi ʻōnaehana paʻa paʻa.
Aia i loko o ka mea hana ʻekolu electrodes, me ka electrode waena ma kekahi ʻaoʻao o ka ceramic piezoelectric i hoʻokaʻawale ʻia mai nā electrodes ma nā ʻaoʻao ʻelua. Ma ka ʻaoʻao ʻē aʻe o ka ceramic piezoelectric, ua hoʻopili ʻia nā electrodes ʻelua i ke kikowaena a me ka lihi o ka ceramic piezoelectric, i kēlā me kēia, e hōʻoia ana i kahi pilina uila paʻa.
Ma waho aʻe o nā resonators me ʻekolu pine, aia kekahi mau mea me nā pine ʻelua wale nō. A laila, e nānā mākou i ʻelua-pin resonator. I ka wehe ʻana, ʻike mākou aia ʻekolu mau ʻāpana, akā ʻaʻole like me ka ceramic piezoelectric, aia nā electrodes e pili ana ma ka ʻaoʻao mua a ma hope. Hoʻopili pū ʻia kēia mau electrodes i ka ceramic piezoelectric ma o ka conductive rubber, e hōʻoia ana i kahi pilina uila paʻa.
