Ii-Linear Resonant Actuators (LRAs) ziye zaba zizinto ezibalulekileyo kwizixhobo ze-elektroniki zanamhlanje, zinika amandla impendulo ye-haptic esiyivayo kwiifowuni eziphathwayo, izixhobo zokunxiba, abalawuli bemidlalo, nokunye. Ngokungafaniyo neemoto zemveli ezijikelezayo ezinobunzima obujikelezayo (ERM) ezixhomekeke kwiisisindo ezijikelezayo, ii-LRA zisebenza ngokomgaqo wokungcangcazela okuvakalayo, zinikezela ngeemvakalelo ezichanekileyo, ezisebenzayo, nezinokwenziwa ngokwezifiso. Apha ngezantsi kukho uhlalutyo oluneenkcukacha lwendlela ezisebenza ngayo ii-LRA, izinto zazo eziphambili, kunye nefiziksi eqhuba ukusebenza kwazo.
Izinto eziphambili zeIsixhobo sokuHlaziya esiLingeneyo
Ukuze uqonde ukusebenza kwe-LRA, kubalulekile kuqala ukuba uhlolisise iindawo zayo eziphambili, nganye kuzo yenzelwe ukuvumela intshukumo evakalayo:
Ukuhlanganiswa kweMagnet: Ngokwesiqhelo imagnethi esisigxina (edla ngokuba yi-neodymium yobuninzi be-magnetic flux), le nxalenye yenza ubunzima obuhambayo be-LRA. Ixhonywe ngaphakathi kwesixhobo, ivumela ukuba ijikeleze ibuyele umva kwaye ibuyele phambili kwi-axis enye yomgca.
Ikhoyili: Ikhoyili ye-electromagnetic engashukumiyo ijikeleza indibano yemagnethi. Xa umsinga wombane uhamba kwikhoyili, uvelisa intsimi yemagnethi esebenzisana nentsimi yemagnethi esisigxina—le ntsebenziswano ngamandla aqhubayo emva kwentshukumo ye-LRA.
Inkqubo Yokuxhoma: Yenziwe ngeesprings eziguquguqukayo (ezidla ngokwenziwa ngesinyithi okanye ngepolymer), inkqubo yokuxhoma ibamba imagnethi endaweni yayo ngelixa ivumela intshukumo ethe tye yomgca. Ikwadlala indima ebalulekileyo ekuchazeni i-frequency ye-LRA evakalayo, njengoko ukuqina kwespring kunye nobunzima bemagnethi kumisela i-frequency yendalo apho inkqubo ingcangcazela khona ngokufanelekileyo.
Indawo yokuhlala: Ibhokisi yangaphandle eqinileyo igquma zonke izinto, inika inkxaso kwisakhiwo kwaye iqinisekisa ukuba intshukumo eshukumayo idluliselwa ngokufanelekileyo kwisixhobo (kwaye ekugqibeleni ifikelele ekuchukumiseni komsebenzisi).
Umgaqo-siseko oSebenzayo: Ukuqaqamba kunye nokusebenzisana kwe-Electromagnetic
I-LRAimoto isebenza ngokusekelwe kwiziganeko ezimbini ezibalulekileyo zomzimba: amandla e-electromagnetic kunye ne-mechanical resonance. Nantsi indlela echazwe ngayo le nkqubo inyathelo ngenyathelo:
Ukuveliswa kwamandla e-electromagnetic: Xa i-voltage ifakwa kwi-coil ye-LRA, i-alternating current (AC) idlula kuyo. Ngokomthetho ka-Ampère, le current idala i-magnetic field etshintsha-tshintsha ngexesha ejikeleze i-coil. Icala lale magnetic field litshintsha nge-polarity yesignali ye-AC (umz., i-positive current idala i-north pole kwelinye icala le-coil, ngelixa i-negative current iyibuyisela kwi-south pole).
Ukusebenzisana kunye nokuHamba kweMagneti: Imagnethi esisigxina ngaphakathi kwi-LRA i-polarized (eneepali ezisemantla nezisemazantsi), ngoko ke ifumana amandla xa ivezwe kwintsimi yemagnethi etshintshanayo yekhoyili. Xa intsimi yemagnethi yekhoyili ihambelana neepali zemagnethi, imagnethi itsalwa iye kwikhoyili; xa intsimi ijika umva, imagnethi iyatyhalelwa kude. La mandla abuyela umva naphambili abangela ukuba imagnethi ijikeleze ngokuthe ngqo kwi-axis yayo.
Ukuhambelana: Ukuphucula ukusebenza kakuhle kunye nobubanzi: Injini ethe tyabaYenzelwe ukusebenza kwi-mechanical resonant frequency yayo—i-frequency yendalo apho inkqubo yokumiswa kunye nobunzima bemagnethi zingcangcazela ngamandla amancinci. Xa i-resonance, i-impedance yenkqubo iyancitshiswa, oko kuthetha ukuba uninzi lwamandla ombane anikezelwa kwi-coil aguqulwa abe yi-mechanical vibration (endaweni yokulahleka njengobushushu). Oku kubangela i-vibration amplitudes enkulu kunye nokusebenza kakuhle okuphezulu xa kuthelekiswa nokusebenza okungekho-resonant. Umzekelo, i-smartphone eqhelekileyo i-LRA ine-frequency ye-resonant ephakathi kwe-100–200 Hz, elungiselelwe ukuqonda komntu okuchukumisayo.
Ukudambisa kunye noLawulo: Nangona isandi senza ukuba ukusebenza kube lula, sikwafuna ulawulo oluchanekileyo ukuze kuthintelwe ukungcangcazela okungazinzanga.iimoto zidibene nabaqhubi abazinikeleyo (abafana neTexas Instruments' DRV2605 okanye iDRV2625) abalawula imvamisa yesignali ye-AC kunye nobukhulu bayo. Aba baqhubi baqinisekisa ukuba i-LRA isebenza ngqo kwimvamisa yayo yokuvakala (ihlawulela utshintsho lokwenziwa okanye utshintsho lobushushu) kwaye ivumela amandla okungcangcazela ahlengahlengiswayo—ukusuka kwiimpompo ezincinci (umz., izilumkiso zesaziso) ukuya kwiipulses ezinamandla (umz., impendulo yokudlala).
Iingenelo eziphambili ze-LRAs ngaphezu kwezinye iiTekhnoloji zeHaptic
Umgaqo wokusebenza ocacileyo unika ii-LRA iingenelo ezahlukeneyo ezenza ukuba zilungele ukusetyenziswa kwezixhobo ze-elektroniki zabathengi:
Ukuchaneka: Ii-LRA ziyangcangcazela ecaleni kwe-axis enye ethe ngqo, zivelisa impendulo ehambelanayo neqikelelweyo yokuchukumisa ngaphandle "kokugquma" okujikelezayo kwee-motor ze-ERM. Oku kuzenza zilungele usetyenziso olufuna iimvakalelo ezicacileyo, ezifana nee-haptics zesikrini sokuchukumisa okanye ukucinezela amaqhosha abonakalayo.
Ukusebenza kakuhle: Ngokusebenzisa isandi esivakalayo, ii-LRA zisebenzisa amandla amancinci kunee-ERM ukuze kubekho isandi esifanayo sokungcangcazela. Oku kubalulekile kwizixhobo ezisebenzisa ibhetri ezifana nee-smartphones kunye nezinto ezinxitywayo, apho ukusebenza kakuhle kwamandla kuyeyona nto iphambili.
Ubungakanani Obuncinci: Ii-LRA zinoyilo oluncinci, oluthe tyaba (oludla ngokuba ziimilimitha ezimbalwa ubukhulu) olungena lula kwiindawo ezixineneyo zezixhobo. Intshukumo yazo ethe tye ikwasusa isidingo sokujikelezisa iindawo, nto leyo enciphisa ubungakanani kunye nobunzima ngokubanzi.
Ixesha Lokuphendula Ngokukhawulezileyo: Uyilo lwemagnethi olukhaphukhaphu kunye noyilo oluphantsi lwe-LRAs luzivumela ukuba ziqale kwaye ziyeke ukungcangcazela phantse ngoko nangoko. Oku kwenza impendulo ekhawulezileyo, elandelelanayo (umz., ukuthayipha kwikhibhodi ebonakalayo) ezivakala ngathi zezendalo kwaye ziphendula.
Izicelo zeHlabathi lokwenyani
Ii-LRA zifumaneka kakhulu kubuchwepheshe banamhlanje, nto leyo ephucula amava abasebenzisi kumashishini onke:
Izixhobo ze-elektroniki zabathengi: Iifowuni eziphathwayo (umz., impendulo ye-haptic yokubhala, ukuzulazula, okanye ukudlala imidlalo), ii-smartwatches (umz., izilumkiso zokungcangcazela zeefowuni okanye iziganeko zokuqina komzimba), kunye neetablethi.
Imidlalo: Abalawuli bee-consoles kunye nemidlalo yeselula, apho ii-haptics ezichanekileyo (umz., ukulinganisa iimpembelelo, umhlaba, okanye ukubuya kwezixhobo) zibenza abadlali bangene kumdlalo.
Iimoto: Iiscreen zokuchukumisa kunye neenkqubo zokuzonwabisa ezimotweni, ezibonelela ngokuqinisekiswa kokuchukumisa kwiinkinobho ukuze kuncitshiswe ukuphazamiseka komqhubi.
Izinto ezinxitywayo kunye nezixhobo zonyango: Izixhobo zokulandelela impilo, izixhobo zokuva, kunye neemonitha zonyango, apho ukungcangcazela okuhlukeneyo kunika izilumkiso ezibalulekileyo ngaphandle komsindo.
Isiphelo
Ii-Linear Resonant Actuators ziguqula impendulo ye-haptic ngokudibanisa itekhnoloji ye-electromagnetic kunye ne-mechanical resonance, zinikezela ngezisombululo zokungcangcazela ezisebenzayo, ezichanekileyo, nezincinci. Ngokuqonda izinto zazo eziphambili—imagnethi, i-coil, i-suspension, kunye ne-housing—kunye nefiziksi yentshukumo ye-resonant, sinokuqonda ukuba kutheni ii-LRA ziye zaba lukhetho oluya kuthandwa ziinjineli eziyila amava okuchukumisa esizukulwana esilandelayo. Nokuba uchwetheza umbhalo, udlala umdlalo, okanye uhamba ngesixhobo esikrelekrele, ukungcangcazela okuthambileyo nokuphendulayo okuvakalelwayo kusenokwenzeka ukuba kuqhutywa ngumgaqo osebenzayo omhle we-linear resonant actuator.
