Kev Taw Qhia Txog Linear Resonant Actuators (LRA)
Haptic feedback tau dhau los ua ib feem tseem ceeb ntawm kev sib cuam tshuam ntawm cov khoom siv niaj hnub no, thiab lub plawv ntawm qhov kev hloov pauv no yog Linear Resonant Actuator (LRA). Tsim los xa cov kev co kom raug, ua haujlwm tau zoo nrog kev siv hluav taws xob tsawg, LRAs tau txhais dua tshiab txog li cas cov neeg siv tau txais kev cuam tshuam tactile thoob plaws hauv kev lag luam.
Tus linear resonant actuator yog dab tsi?
Ib qho Linear Resonant Actuator (LRA) yog ib qho khoom siv hluav taws xob uas hloov lub zog hluav taws xob mus rau hauv kev co linear ntawm nws qhov zaus resonant. Tsis zoo li cov motors eccentric rotating mass, LRAs xa cov lus teb sai, kev tswj kev co meej, thiab cov yam ntxwv me me - ua rau lawv zoo tagnrho rau cov khoom siv hluav taws xob xws li cov cuab yeej zoo nkauj, e-luam yeeb, thiab smartwatches. Peb cov Z-axis LRAs tau tsim los co raws txoj kab ntsug, kom ntseeg tau tias muaj kev tawm tswv yim zoo thiab kev sib koom ua ke rau hauv cov qauv tsim khoom me me.
Qhov Tseem Ceeb ntawm Kev Xaiv LRA Zoo
Kev xaiv lub LRA kom raug yog qhov tseem ceeb rau kev ua tiav ntawm koj qhov project. Lub actuator tsis sib xws tuaj yeem ua rau muaj kev co tsis muaj zog, siv hluav taws xob ntau dhau, muaj teeb meem kev sib koom ua ke, lossis kev paub tsis zoo ntawm tus neeg siv. Rau cov khoom siv zoo nkauj, kev co txhim khu kev qha ua rau kev saib xyuas tawv nqaij zoo dua; rau cov luam yeeb hluav taws xob, cov lus teb kov tau zoo lees paub cov haujlwm ntawm tus neeg siv; rau cov smartwatches, cov lus ceeb toom meej meej txhim kho kev siv tau. Peb lub LRA motors yog tsim los daws cov teeb meem siv no, sib npaug kev ua tau zoo, qhov loj me, thiab tus nqi rau cov txiaj ntsig zoo tshaj plaws.
Cov Yam Tseem Ceeb Yuav Tsum Xav Txog Thaum Xaiv LRA
Kev xaiv tus Linear Resonant Actuator (LRA) uas yog qhov tseem ceeb rau kev ua kom zoo dua ntawm kev tawm tswv yim haptic, kev ua haujlwm ntawm lub cuab yeej, thiab kev paub ntawm tus neeg siv. Txij li qhov zaus ntawm kev co thiab daim ntawv mus rau kev siv hluav taws xob zoo, txhua qhov kev ntsuas kev siv tshuab cuam tshuam ncaj qha rau qhov zoo ntawm LRA sib xyaw rau hauv koj cov khoom thiab xa cov lus teb tactile uas xav tau.
Zaus
