Linear vibration motors yog siv dav hauv xov tooj ntawm tes, smartphones, cov khoom siv hnav thiab lwm yam khoom siv me me uas xav tau kev ua haujlwm vibration.
2. Tsav Tsheb IC
Lub cev muaj zog linear micro LD0832 & LD0825 yuav tsum siv nrog lub tsav IC xws li TI DRV2604L lossis DRV2605L. TI (Texas Instruments) muag lub rooj tsav xwm soj ntsuam nrog lub IC chip no rau nws. Mus saib qhov txuas: https://www.ti.com/lsds/ti/motor-drivers/motor-haptic-driver-products.page
Yog tias koj xav tau IC uas pheej yig dua, peb tuaj yeem pom zoo rau koj cov neeg muab khoom Suav nrog tib qho kev ua tau zoo tab sis tus nqi pheej yig.
3. Lub LRA Ua Ib Qho Cheebtsam ntawm Circuit Court
Thaum LRA motors raug koom ua ke rau hauv ib lub voj voog, lawv feem ntau yooj yim dua li lawv lub voj voog sib npaug, tshwj xeeb tshaj yog thaum tsav los ntawm lub chip tsav tsheb LRA tshwj xeeb xws li DRV2603. Los ntawm kev txuas LRA rau cov pins tsim nyog ntawm IC sawv ntsug, cov neeg tsim qauv thiab cov engineers tuaj yeem txuag lub sijhawm thiab tsom mus rau lwm yam ntawm lub kaw lus.
Txawm hais tias LRA tsim cov EMF rov qab los ntawm, ntau tus tsav tsheb LRA siv cov nyhuv no ua lub tshuab ntsuas. Qee tus tsav tsheb IC ntsuas EMF rov qab. Lawv siv cov ntaub ntawv no los kho qhov zaus ntawm lub teeb liab tsav tsheb kom pom qhov resonance. Nws ua rau cov khoom ua haujlwm hauv cov kev txwv thiab qib ze dua tsis hais txog cov xwm txheej lossis hnub nyoog.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias LRA lub cev muaj zog yog cov uas tsis muaj txhuam. Lawv tsis raug kev txom nyem los ntawm cov pa hluav taws xob uas cuam tshuam nrog commutator arcing hauv DC ERM lub cev muaj zog. Cov yam ntxwv no, zoo ib yam li cov cav tsis muaj txhuam ERM, feem ntau ua rau LRAs tsim nyog rau cov khoom siv ATEX tau ntawv pov thawj.
4. Tsav Tsheb Linear Resonant Actuators / Linear Vibrators
Cov vibrators linear LRA xav tau lub teeb liab AC kom ua haujlwm tau zoo, zoo ib yam li cov neeg hais lus. Nws yog qhov zoo tshaj plaws los siv lub teeb liab sine wave ntawm qhov zaus resonant, raws li pom hauv daim duab hauv qab no.
Tau kawg, qhov amplitude ntawm lub tsav waveform tuaj yeem hloov kho kom tsim cov teebmeem tactile feedback ntau dua.
5. Lub Neej Ntev Rau Cov Tshuab Vibrators
LRA vibration motors txawv ntawm feem ntau vibration motors uas lawv siv lub suab coil los tsav lub pawg, ua rau lawv tsis txhuam tau zoo.
Tus qauv tsim no txo qhov ua tau ntawm kev ua tsis tiav ntawm lub caij nplooj ntoos hlav, uas yog qauv siv kev tshuaj xyuas qhov kawg (FEA) thiab ua haujlwm hauv thaj chaw tsis qaug zog. Vim tias kev hnav khoom siv tsawg heev thiab hom kev ua tsis tiav tseem ceeb tsuas yog txwv rau kev laus ntawm cov khoom sab hauv, lub sijhawm nruab nrab kom ua tsis tiav (MTTF) ntev dua piv rau cov tshuab hluav taws xob brushed eccentric rotating mass (ERM) vibration.
