Kua noho ngā Linear Resonant Actuators (LRA) hei wāhanga tino nui i roto i ngā taputapu hiko hou, e whakakaha ana i te urupare haptic e rongohia ana e tātou i roto i ngā waea atamai, i ngā taputapu mau, i ngā kaiwhakahaere petipeti, me ētahi atu. He rerekē ki ngā motuka papatipu hurihuri eccentric tuku iho (ERM) e whakawhirinaki ana ki ngā taumaha hurihuri, ka mahi ngā LRA i runga i te kaupapa o te wiri resonant, e tuku ana i ngā kare ā-pā tika, whai hua, me te taea te whakarite. Kei raro nei he whakamārama taipitopito mō te mahi a ngā LRA, ō rātou wāhanga matua, me te ahupūngao e akiaki ana i tā rātou mahi.
Ngā Wāhanga Matua o tētahiKaiwhakaoho Āhuatanga Raina
Hei mārama ki te mahi a te LRA, he mea nui kia tirohia ōna wāhanga matua, ia wāhanga i hangaia hei whakahohe i te nekehanga orooro:
Huinga Aukume: He aukume tuturu tēnei (he neodymium te nuinga mō te nui o te rerenga aukume), ā, ko tēnei wāhanga te mea e hanga ana i te papatipu neke o te LRA. Kei roto i te taputapu e iri ana, e āhei ai te neke whakamua me te haere whakamua i te tuaka rārangi kotahi.
Koiri: He koiri hiko pūmau e karapoti ana i te huihuinga aukume. Ina rere te iahiko i roto i te koiri, ka puta he papa aukume e taunekeneke ana me te papa o te aukume tuturu—koinei te taunekeneke te kaha akiaki i muri i te nekehanga o te LRA.
Pūnaha Whakatārewatanga: He mea tito mai i ngā puna ngāwari (he maha ngā wā he mea hanga ki te konganuku, ki te pūmua rānei), ka pupuri te pūnaha whakatārewatanga i te aukume ki tōna tūranga, me te whakahohe i te nekehanga raina maeneene. He mahi nui anō hoki tāna ki te tautuhi i te auau haruru o te LRA, nā te mea ko te pakari o te puna me te papatipu o te aukume te whakatau i te auau tūturu e wiri pai ai te pūnaha.
Whare: Ka takai te anga o waho pakari i ngā wāhanga katoa, hei tautoko i te hanganga, hei whakarite hoki kia pai te tuku i te nekehanga wiri ki te pūrere (ā, ki te pā atu hoki o te kaiwhakamahi).
Te Mātāpono Mahi Taketake: Te Āhuatanga me te Taunekeneke Hikohiko
LRAmōta e mahi ana i runga i ngā āhuatanga ā-tinana matua e rua: te kaha hikohiko me te haruru ā-pūkaha. Anei tētahi whakamārama taahiraa-i-te-taahiraa o te tukanga:
Te Whakaputa i te Kaha Hikohiko: Ina tukuna he ngaohiko ki te pōkai o te LRA, ka rere he au hurihuri (AC) mā roto. E ai ki te ture a Ampère, ka hangaia e tēnei au he papa aukume e rerekē ana te wā huri noa i te pōkai. Ka huri te ahunga o tēnei papa aukume ki te polarity o te tohu AC (hei tauira, ka hangaia e te au pai he pou raki i tetahi pito o te pōkai, ko te au kino ka huri ki te pou tonga).
Te Taunekeneke me te Taunekeneke Aukume: He porowhita te aukume tuturu i roto i te LRA (me ngā pou raki me ngā pou tonga), nō reira ka pāngia e te kaha ina pāngia e te papa aukume tauutuutu o te koiri. Ina rite te papa aukume o te koiri ki ngā pou o te aukume, ka tōia te aukume ki te koiri; ina huri te papa, ka panaia te aukume. Mā tēnei kaha whakamuri, whakamuri ka huri te aukume i tōna tuaka.
Te Whakarei: Te Whakanui i te Whai Hua me te Whānui: Te motuka rainakua hangaia kia mahi i tōna auau ā-pūkaha - te auau tūturu e wiri ai te pūnaha whakatārewatanga me te papatipu aukume me te iti o te whakaurunga pūngao. I te ā-ā-ā-ā, ka whakaitihia te aukati o te pūnaha, ko te tikanga ko te nuinga o te pūngao hiko e tukuna ana ki te koiri ka hurihia hei wiri ā-pūkaha (kaua e ngaro hei wera). Ka hua ake tēnei i ngā kaha wiri nui ake me te pai ake o te whai huatanga ki te whakataurite ki te mahi kore-ā-ā. Hei tauira, he auau ā-ā-ā o te LRA waea atamai noa i waenga i te 100–200 Hz, he mea arotau mō te tirohanga pā o te tangata.
Te Whakaiti me te Whakahaere: Ahakoa ka whakanui ake te haruru i te pai o te mahi, me whakahaere tika hoki kia kore ai e pāngia e ngā wiri kore pumau. Ko te nuinga o te LRAngā motuka ka honoa ki ngā taraiwa motuhake (pērā i te DRV2605, DRV2625 rānei a Texas Instruments) e whakahaere ana i te auau me te kaha o te tohu AC. Mā ēnei taraiwa ka whakarite kia mahi tika te LRA i tōna auau haruru (hei utu mō ngā rerekētanga hanga, ngā huringa pāmahana rānei) ā, ka taea te whakarerekē i te kaha o te wiri—mai i ngā pato ngawari (hei tauira, ngā matohi whakamōhiotanga) ki ngā pāorooro kaha (hei tauira, te urupare petipeti).
Ngā Painga Matua o ngā LRA ki ngā Hangarau Haptic kē atu
Nā te mātāpono mahi āwhati ka hoatu ki ngā LRA ētahi painga motuhake e pai ai mō ngā hikohiko kaihoko:
Te Tika: Ka wiri ngā LRA i te tuaka rārangi kotahi, ka puta he urupare pā rite tonu, ka taea te matapae, me te kore e rangona te "haruru" hurihuri o ngā motuka ERM. Nā tēnei ka tino pai mō ngā tono e hiahia ana ki ngā kare ā-roto matatini, pērā i ngā mahi pā-mata, ngā pēhi pātene mariko rānei.
Whai Hua: Mā te whakamahi i te haruru, ka iti ake te hiko e pau ana i ngā LRA i ngā ERM mō te kaha wiri ōrite. He mea nui tēnei mō ngā taputapu pākahiko pēnei i ngā waea atamai me ngā taputapu mau, he mea nui te whai huatanga o te pūngao.
Rahi Kiato: He angiangi, he papatahi te hoahoa o ngā LRA (he torutoru mirimita te matotoru) ka uru ngāwari ki roto i ngā taupoki taputapu kikī. Nā te nekehanga rārangi, ka kore e hiahiatia he wāhanga hurihuri, ka whakaitihia te rahi me te taumaha katoa.
Wā Urupare Tere: Mā te aukume māmā me te hoahoa iti-aukati o ngā LRA ka taea e rātou te tīmata me te mutu te wiri tata tonu. Mā tēnei ka taea te urupare tere, raupapa (hei tauira, te pato i runga i te papapātuhi mariko) e ahua maori ana, e aro ana hoki.
Ngā Taupānga o te Ao Tūturu
Kei ngā wāhi katoa ngā LRA i roto i ngā hangarau hou, e whakarei ake ana i ngā wheako kaiwhakamahi puta noa i ngā ahumahi:
Ngā Hikohiko Kaihoko: Ngā Waea Atamai (hei tauira, te urupare haptic mō te pato, te whakatere, te petipeti rānei), ngā mataarataki atamai (hei tauira, ngā whakatūpato wiri mō ngā waeatanga, ngā tohu whakapakari tinana rānei), me ngā papahiko.
Te Keemu: Ngā pūmana whakahaere mō ngā papatohu me ngā kēmu pūkoro, e tuku ana i ngā kaitākaro ki te tākaro i ngā nekehanga tika (hei tauira, te whakatauira i ngā pānga, te whenua, te hoki whakamuri rānei).
Aunoa: Ngā mata pā me ngā pūnaha whakangahau i roto i ngā motuka, e whakarato ana i te whakaū pā mō ngā pēhitanga pātene hei whakaiti i te whakararuraru a te taraiwa.
Ngā Pūrere Kakahu me ngā Pūrere Hauora: Ngā taputapu aroturuki hauora, ngā taputapu whakarongo, me ngā taputapu aroturuki hauora, e tukuna ana e ngā wiri motuhake ngā whakatūpato nui me te kore oro.
Whakamutunga
Ka hurihia e ngā Pūwhakaoho Resonant Raina te urupare haptic mā te whakakotahi i te hangarau hikohiko me te orooro ā-mīhini, ka tukuna he otinga wiri whai hua, tika, me te kiato. Mā te mārama ki ō rātou wāhanga matua—te aukume, te koiri, te whakatārewatanga, me te whare—me te ahupūngao o te nekehanga orooro, ka taea e tātou te mārama he aha i waiho ai ngā LRA hei whiringa matua mā ngā kaihangarau e hoahoa ana i ngā wheako pā o te whakatupuranga e whai ake nei. Ahakoa kei te pato koe i tētahi tuhinga, kei te tākaro kēmu, kei te whakatere rānei i tētahi taputapu atamai, ko te wiri maeneene, urupare e rongohia ana e koe ka whakakahangia pea e te mātāpono mahi huatau o tētahi pūwhakaoho resonant raina.
Kōrero ki ō Tohunga Kaiārahi
Ka āwhina mātou i a koe ki te karo i ngā mahanga hei whakatutuki i te kounga me te uara o tō motuka paraihe iti e hiahiatia ana, i te wā tika me te tahua.
