Linear Resonant Actuators (LRAs) dzave zvinhu zvakakosha mumidziyo yemazuva ano yemagetsi, zvichipa simba remhinduro yehaptic yatinonzwa mumafoni, zvinopfekwa, zvinodzora mitambo, nezvimwewo. Kusiyana nemamota ekare anotenderera mass (ERM) anovimba nehuremu hwekutenderera, maLRA anoshanda nepfungwa yekudengenyeka kwe resonant, achipa manzwiro ekubata akanyatsojeka, anoshanda zvakanaka, uye anogadziriswa. Pazasi pane kupatsanurwa kwakadzama kwekushanda kwemaLRA, zvikamu zvawo zvikuru, uye fizikisi inofambisa mashandiro awo.
Zvikamu Zvikuru zveChinogadzirisa Zvinoita Kuti Unzwe Uchifara
Kuti unzwisise mashandiro eLRA, zvakakosha kutanga waongorora zvikamu zvayo zvakakosha, chimwe nechimwe chakagadzirirwa kugonesa kufamba kwenzwi:
Kuungana kweMagineti: Kazhinji magineti inogara iripo (kazhinji neodymium yehuwandu hwemagineti akawandisa), chikamu ichi chinoumba huremu hunofamba hweLRA. Inorembera mukati memudziyo, zvichiita kuti itenderere mberi nekudzoka ichitevedza axis imwe chete.
Coil: Coil yemagetsi isingachinji inokomberedza mubatanidzwa wemagineti. Kana magetsi emagetsi achifamba nemucoil, anogadzira simba remagineti rinoshanda nesimba remagineti risingaperi—kubatana uku ndiko kunoita kuti LRA ifambe.
Sisitimu Yokumisa: Yakagadzirwa nezvitubu zvinochinjika (zvinowanzogadzirwa nesimbi kana polymer), sisitimu yekumisa inochengeta magineti panzvimbo yayo uku ichigonesa kufamba kwakatsetseka. Inoitawo basa rakakosha mukutsanangura frequency yeLRA, sezvo kuoma kwechitubu nehuremu hwemagineti zvinosarudza frequency yechisikigo iyo sisitimu inodedera zvakanyanya.
Dzimba: Chivharo chekunze chakasimba chinofukidza zvikamu zvese, zvichipa rutsigiro rwechimiro uye zvichiita kuti kufamba kwechinhu ichi kuendeswe zvakanaka kuchishandiso (uye pakupedzisira kuchibata nemushandisi).
Nheyo Yekushanda Yekutanga: Kubatana Kwemagetsi uye Kubatana Kwemagetsi
LRAmota Inoshanda zvichibva pazvinhu zviviri zvakakosha zvemuviri: simba remagetsi uye kurira kwemagetsi. Heino kupatsanurwa kwemaitiro acho nhanho nhanho:
Kugadzirwa kweSimba reMagineti: Kana voltage ikaiswa pacoil yeLRA, alternating current (AC) inoyerera nepakati payo. Sekureva kwemutemo waAmpère, simba iri rinogadzira simba remagineti rinotenderera coil rinochinja-chinja. Kutungamira kwesimba iri remagineti kunochinja ne polarity yechiratidzo cheAC (semuenzaniso, simba remagineti rinogadzira pole yekuchamhembe kune rimwe divi recoil, nepo simba remagineti richiridzosera kupole yekuchamhembe).
Kubatana uye Kufamba kweMagineti: Magineti inogara iri mukati meLRA ine polarized (nemapore ekuchamhembe nekuchamhembe), saka inosangana nesimba kana yaiswa pamunda wemagineti wecoil unochinjana. Kana simba remagineti recoil rakabatana nemapore emagneti, magineti anodhonzwa akananga kucoil; kana munda ukadzokera shure, magineti inosundirwa kure. Simba iri rekudzokera shure nerekumashure rinoita kuti magineti atenderere zvakananga padivi rayo.
Kubatana: Kuwedzera Kushanda Nesimba uye Kukura: Mota ine mutsaraYakagadzirirwa kushanda pa frequency yayo ye mechanical resonant—frequency yechisikigo iyo suspension system uye magnet mass zvinodedera nesimba shoma. Pa resonance, impedance ye system inoderedzwa, zvichireva kuti simba guru remagetsi rinopihwa ku coil rinoshandurwa kuita mechanical vibration (pane kurasika sekupisa). Izvi zvinoguma ne vibration amplitudes yakakura uye kushanda zvakanaka kwepamusoro zvichienzaniswa ne non-resonant operation. Semuenzaniso, smartphone yakajairika LRA ine resonant frequency iri pakati pe100–200 Hz, iyo yakagadzirirwa kuti munhu anzwisise kubata.
Kuderedza uye Kudzora: Kunyange zvazvo resonance ichisimudzira kushanda zvakanaka, inodawo kudzora kwakarurama kudzivirira kudedera kusina kugadzikana.mota zvinobatanidzwa nemadhiraivha akazvipira (akadai seTexas Instruments' DRV2605 kana DRV2625) anodzora frequency uye amplitude yechiratidzo cheAC. Madhiraivha aya anovimbisa kuti LRA inoshanda nemafrequency ayo chaiwo (ichitsiva shanduko dzekugadzira kana shanduko dzetembiricha) uye inobvumira kuchinjika kwesimba rekudengenyeka—kubva pamatapu madiki (semuenzaniso, zviziviso zvekuzivisa) kusvika kumapulse akasimba (semuenzaniso, mhinduro yemitambo).
Mabhenefiti Akakosha eLRAs Pamusoro Pemamwe Matekinoroji EHaptic
Nheyo yekushanda ine resonant inopa maLRA mabhenefiti akasiyana-siyana anoita kuti ave akakodzera kushandiswa kwemagetsi evatengi:
Kunyatsojeka: MaLRA anodedera achifamba nemutsetse mumwe chete, achiburitsa mhinduro dzinoenderana, dzinofungidzirwa dzekubata pasina "rumble" inotenderera yemamota eERM. Izvi zvinoita kuti akwane maapplication anoda kunzwa kwakanyatsojeka, senge touchscreen haptics kana kuti virtual button presses.
Kushanda Nesimba: Nekushandisa resonance, maLRA anoshandisa simba shoma pane maERM kuti akwanise kutenderera zvakafanana. Izvi zvakakosha kune zvishandiso zvinoshandisa mabhatiri zvakaita semafoni nemidziyo inopfekwa, uko kushanda nesimba kuri chinhu chinonyanya kukosheswa.
Saizi Yakabatana: MaLRA ane dhizaini yakatetepa, yakati sandara (kazhinji ine ukobvu hwemamirimita mashoma) inokodzera zviri nyore mumidziyo yakasimba. Kufamba kwawo kwakatwasuka kunobvisawo kudiwa kwekutenderera kwezvikamu, zvichideredza saizi nehuremu hwese.
Nguva Yekukurumidza Kupindura: Magnet yakareruka uye dhizaini yeLRAs isinganyanyi kunonoka inovabvumira kutanga nekumira kudedera nekukurumidza. Izvi zvinogonesa mhinduro dzinokurumidza, dzakatevedzana (semuenzaniso, kunyora pakiyibhodhi chaiyo) dzinoita sedzechisikigo uye dzinopindura.
Zvishandiso zveNyika Chaiyo
MaLRA anowanikwa kwose kwose mu tekinoroji yemazuva ano, zvichiwedzera ruzivo rwevashandisi mumaindasitiri akasiyana siyana:
Makombiyuta eVatengi: Mafoni (semuenzaniso, mhinduro yekunyora, kufamba, kana kutamba mitambo), mawachi ekuchenjera (semuenzaniso, zviziviso zvekudedera kana zviitiko zvekusimba kwemuviri), uye matableti.
Kutamba Mitambo: Zvinodzora mitambo yemakombiyuta nemitambo yemafoni, uko mitambo chaiyo (semuenzaniso, kutevedzera mhedzisiro, nzvimbo, kana kudzokera shure kwezvombo) zvinonyudza vatambi mumutambo.
Mota: Matochini ekubata uye masisitimu ekufambisa mashoko mumota, zvichipa kusimbiswa kwekubatika kwemabhatani ekuderedza kukanganiswa kwemutyairi.
Zvishandiso Zvinopfekwa Nemidziyo Yekurapa: Zvishandiso zvekugwinya muviri, zvinhu zvinobatsira kunzwa, uye mamonita ekurapa, uko kutetepa kwakasiyana kunopa nyevero dzakakosha pasina ruzha.
Mhedziso
Linear Resonant Actuators inoshandura mhinduro yehaptic nekubatanidza tekinoroji yemagetsi ne mechanical resonance, ichipa mhinduro dzinoshanda, dzakarurama, uye dzakasimba dzekudedera. Nekunzwisisa zvikamu zvavo zvikuru—magnet, coil, suspension, uye housing—uye fizikisi yekufamba kwe resonant, tinogona kunzwisisa kuti nei maLRA ave sarudzo yeinjiniya yekugadzira zviitiko zvekubata zvechizvarwa chinotevera. Ungave uri kunyora rugwaro, kutamba mutambo, kana kushandisa mudziyo wakangwara, kudedera kwakapfava, kunopindura kwaunonzwa kunokonzerwa nepfungwa yekushanda kwakanaka kwe linear resonant actuator.
Bvunza Nyanzvi dzeMutungamiriri Wako
Tinokubatsira kudzivirira matambudziko ekupa mhando yepamusoro uye kukoshesa zvaunoda, panguva uye nebhajeti.
