Ama-Linear Resonant Actuators (ama-LRA) aseyizingxenye ezibalulekile kumadivayisi esimanje kagesi, anika amandla impendulo ye-haptic esiyizwayo kuma-smartphone, izinto ezigqokwayo, abalawuli bemidlalo, nokuningi. Ngokungafani nama-motor endabuko ajikelezayo ngobuningi (i-ERM) ancike ezisindweni ezijikelezayo, ama-LRA asebenza ngesimiso sokudlidliza okuzwakalayo, aletha imizwa yokuthinta eqondile, ephumelelayo, futhi engenziwa ngezifiso. Ngezansi ukuhlukaniswa okuningiliziwe kwendlela ama-LRA asebenza ngayo, izingxenye zawo eziyinhloko, kanye ne-physics eqhuba ukusebenza kwawo.
Izingxenye Eziyinhloko ze-I-Actuator ye-Linear Resonant
Ukuze uqonde ukusebenza kwe-LRA, kubalulekile kuqala ukuhlola izingxenye zayo ezibalulekile, ngayinye eyenzelwe ukuvumela ukunyakaza okuzwakalayo:
Ukuhlanganiswa Kwamaginethi: Ngokuvamile i-magnet ehlala njalo (ngokuvamile i-neodymium yokuminyana okuphezulu kwe-magnetic flux), le ngxenye yakha isisindo esinyakazayo se-LRA. Ilenga ngaphakathi kwedivayisi, okuvumela ukuthi inyakaze iye emuva naphambili nge-axis eyodwa eqondile.
Ikhoyili: Ikhoyili kagesi engaguquki izungeza ukuhlanganiswa kwemagnethi. Lapho ugesi ugeleza kukhoyili, ukhiqiza insimu yamagnetic esebenzisana nensimu yamagnethi ehlala njalo—lokhu kusebenzisana kungamandla aqhubayo ngemuva kokunyakaza kwe-LRA.
Uhlelo Lokumiswa: Lwakhiwe ngeziphethu eziguquguqukayo (ngokuvamile ezenziwe ngensimbi noma nge-polymer), uhlelo lokumiswa lubamba i-magnet endaweni ngenkathi luvumela ukunyakaza okubushelelezi okuqondile. Luphinde ludlale indima ebalulekile ekuchazeni imvamisa ye-LRA ezwakalayo, njengoba ukuqina kwentwasahlobo kanye nobukhulu be-magnet kunquma imvamisa yemvelo lapho uhlelo ludlidliza khona kahle kakhulu.
Indawo yokuhlala: Ibhokisi langaphandle eliqinile limboza zonke izingxenye, lihlinzeka ngokusekelwa kwesakhiwo futhi liqinisekise ukuthi ukunyakaza okuguquguqukayo kudluliselwa ngempumelelo kudivayisi (futhi ekugcineni ngokuthintwa ngumsebenzisi).
Isimiso Sokusebenza Esiyisisekelo: Ukuzwana Nokuxhumana Kwama-Electromagnetic
I-LRAinjini isebenza ngokusekelwe ezimweni ezimbili ezibalulekile zomzimba: amandla kagesi kanye nokuzwakala komshini. Nasi ukuhlukaniswa kwenqubo ngesinyathelo ngesinyathelo:
Ukukhiqizwa Kwamandla Kagesi: Uma i-voltage ifakwa kukhoyili ye-LRA, i-alternating current (AC) igeleza kuyo. Ngokomthetho ka-Ampère, le current idala insimu yamagnetic eshintshashintshayo ngesikhathi ezungeze ikhoyili. Isiqondiso sale nsimu yamagnetic siyashintsha nge-polarity yesignali ye-AC (isb., i-positive current idala i-north pole kolunye uhlangothi lwekhoyili, kuyilapho i-negative current iyibuyisela e-south pole).
Ukusebenzisana Nokunyakaza Kwamagnetic: Imagnethi ehlala njalo ngaphakathi kwe-LRA ihlukaniswe nge-polarized (enezinsika zasenyakatho naseningizimu), ngakho-ke izwa amandla lapho ivezwa ensimini yamagnetic eshintshanayo ye-coil. Lapho insimu yamagnetic ye-coil ihambisana nezinsika zamagnethi, imagnethi idonswa iye ku-coil; lapho insimu iphenduka, imagnethi iyasunduzelwa kude. La mandla abuyela emuva naphambili abangela ukuthi imagnethi inyakaze ngokulandelana eceleni kwe-axis yayo.
Ukuqina: Ukwandisa Ukusebenza Kahle Nokuphakama: Injini eqondileiklanyelwe ukusebenza ngemvamisa yayo ye-mechanical resonant—imvamisa yemvelo lapho uhlelo lokumiswa kanye ne-magnet mass kudlidliza khona ngamandla amancane okufaka. Lapho kuzwakala i-resonance, i-impedance yesistimu iyancishiswa, okusho ukuthi iningi lamandla kagesi anikezwa ku-coil aguqulwa abe ukudlidliza kwe-mechanical (kunokuba alahleke njengokushisa). Lokhu kuphumela kuma-amplitude amakhulu okudlidliza kanye nokusebenza kahle okuphezulu uma kuqhathaniswa nokusebenza okungena-resonant. Isibonelo, i-LRA ejwayelekile ye-smartphone inemvamisa ye-resonant ephakathi kuka-100–200 Hz, elungiselelwe ukuqonda komuntu okuthintekayo.
Ukudambisa Nokulawula: Nakuba i-resonance ikhulisa ukusebenza kahle, idinga nokulawula okunembile ukuze kugwenywe ukudlidliza okungazinzile. Iningi le-LRA lisebenzisa i-resonance.ama-motor zihambisana nabashayeli abazinikele (njenge-Texas Instruments' DRV2605 noma i-DRV2625) abalawula imvamisa kanye nobukhulu besiginali ye-AC. Laba bashayeli baqinisekisa ukuthi i-LRA isebenza kahle ngemvamisa yayo yokuzwana (ikhokhela ukushintshashintsha kokukhiqiza noma izinguquko zokushisa) futhi ivumela amandla okudlidliza alungisekayo—kusukela kuma-taps amancane (isb., izexwayiso zesaziso) kuya kuma-pulse aqinile (isb., impendulo yokudlala).
Izinzuzo Eziyinhloko Zama-LRA Ngaphezu Kwamanye Ama-Haptic Technologies
Isimiso sokusebenza esivumelanayo sinikeza ama-LRA izinzuzo eziningana ezihlukile ezenza afaneleke kakhulu kuma-electronics abathengi:
Ukunemba: Ama-LRA ayadlidliza nge-axis eyodwa eqondile, ekhiqiza impendulo ehambisanayo neqondakalayo yokuthinta ngaphandle "kokuduma" okujikelezayo kwama-motor e-ERM. Lokhu kuwenza afaneleke kakhulu ezinhlelweni zokusebenza ezidinga imizwa ehlukahlukene, njenge-touchscreen haptics noma ukucindezela izinkinobho ezibonakalayo.
Ukusebenza Kahle: Ngokusebenzisa i-resonance, ama-LRA asebenzisa amandla amancane kune-ERM ukuze kube nobukhulu obufanayo bokudlidliza. Lokhu kubalulekile kumadivayisi asebenzisa ibhethri njengama-smartphone kanye nezinto ezigqokwayo, lapho ukusebenza kahle kwamandla kuyinto eza kuqala.
Usayizi Omncane: Ama-LRA anomklamo omncane, oyisicaba (ngokuvamile angamamilimitha ambalwa ubukhulu) ofanelana kalula nezindawo eziqinile zokuvala amadivayisi. Ukunyakaza kwawo okuqondile kuqeda nesidingo sokujikeleza izingxenye, kunciphisa usayizi kanye nesisindo iyonke.
Isikhathi Sokuphendula Okusheshayo: Umklamo we-magnet olula kanye ne-low-inertia wama-LRA uwavumela ukuthi aqale futhi ayeke ukudlidliza cishe ngokushesha. Lokhu kuvumela impendulo esheshayo, elandelanayo (isb., ukuthayipha kukhibhodi ebonakalayo) ezwakala ingokwemvelo futhi iphendula.
Izinhlelo Zokusebenza Zangempela
Ama-LRA atholakala kabanzi kwezobuchwepheshe besimanje, okuthuthukisa ulwazi lomsebenzisi kuzo zonke izimboni:
Ama-Consumer Electronics: Ama-Smartphones (isb., impendulo ye-haptic yokuthayipha, ukuzulazula, noma ukudlala imidlalo), ama-smartwatches (isb., izexwayiso zokudlidliza zezingcingo noma izigigaba zokufaneleka komzimba), kanye namathebulethi.
Imidlalo: Abalawuli bama-consoles nemidlalo yeselula, lapho ama-haptic aqondile (isb., ukulingisa imiphumela, indawo, noma ukubuyela emuva kwezikhali) efaka abadlali ekudlaleni umdlalo.
Izimoto: Izikrini zokuthinta kanye nezinhlelo zokuzijabulisa ezimotweni, okunikeza isiqinisekiso sokuthinta sokucindezela izinkinobho ukuze kuncishiswe ukuphazamiseka komshayeli.
Izinto Ezigqokwayo Namadivayisi Ezokwelapha: Izilandeli zokufaneleka komzimba, izinsiza zokuzwa, kanye neziqaphi zezokwelapha, lapho ukudlidliza okuhlukile kuletha khona izexwayiso ezibalulekile ngaphandle komsindo.
Isiphetho
Ama-Linear Resonant Actuators aguqula impendulo ye-haptic ngokuhlanganisa ubuchwepheshe be-electromagnetic ne-mechanical resonance, alethe izixazululo zokudlidliza ezisebenzayo, ezinembile, nezincane. Ngokuqonda izingxenye zazo eziyinhloko—i-magnet, i-coil, i-suspension, kanye ne-housing—kanye ne-physics yokunyakaza kwe-resonant, singaqonda ukuthi kungani ama-LRA eseyisinqumo esikhethwa onjiniyela abaklama okuhlangenwe nakho kokuthinta kwesizukulwane esilandelayo. Kungakhathaliseki ukuthi uthayipha umbhalo, udlala umdlalo, noma uhamba ngedivayisi ehlakaniphile, ukudlidliza okubushelelezi nokuphendulayo okuzwayo cishe kuqhutshwa yisimiso sokusebenza esihle se-linear resonant actuator.
