Ukuhlasela kwe-Laser kumakrofoni wezinhlelo zokulawula izwi

Abacwaningi abavela eNyuvesi yaseMichigan nase-Osaka University ithuthukisiwe indlela entsha yokuhlasela Imiyalo ekhanyayo, okukuvumela ukuthi ulingise ukude imiyalo yezwi usebenzisa i-laser kumadivayisi asekela ukulawulwa kwezwi, njengezipikha ezihlakaniphile, amaphilisi, ama-smartphone namasistimu okulawula asekhaya ahlakaniphile usebenzisa i-Google Assistant, i-Amazon Alexa, i-Facebook Portal ne-Apple Siri. Ngesikhathi sokuhlolwa, kwaboniswa ukuhlasela okwenze kwaba nokwenzeka ukufihla umyalo wezwi osuka ebangeni elingamamitha angu-75 ngengilazi yefasitela namamitha angu-110 endaweni evulekile.

Ukuhlasela kusekelwe ekusetshenzisweni umphumela we-photoacoustic, lapho ukumuncwa kokukhanya okuguquguqukayo (okuguquliwe) ngento kuholela ekuthokoziseni okushisayo kwe-medium, ukuguqulwa kokuminyana kwezinto kanye nokubukeka kwamagagasi omsindo abonwa yi-membrane yemakrofoni. Ngokumodela amandla e-laser futhi ugxilise ugongolo embobeni ngombhobho, ungafinyelela ukushukunyiswa kokudlidliza komsindo okungeke kuzwakale kwabanye, kodwa okuzobonwa imakrofoni.

Ukuhlasela kuthinta imibhobho ye-electromechanical esetshenziswa kumadivayisi wesimanje (I-MEMS).
Phakathi kwamadivayisi abathengi ahlolelwe ukuthambekela enkingeni kukhona amamodeli ahlukahlukene e-Google Home, Google NEST, Amazon Echo, Echo Plus/Spot/Dot, Facebook Portal Mini, Fire Cube TV, EchoBee 4, iPhone XR, iPad 6th Gen, Samsung Galaxy. I-S9 ne-Google Pixel 2, nazo izikhiya ezihlakaniphile nezinhlelo zokulawula izwi zezimoto zakwaTesla nezakwaFord. Usebenzisa indlela yokuhlasela ehlongozwayo, ungakwazi ukulingisa ngokukhipha umyalo wokuvula umnyango wegaraji, uthenge ku-inthanethi, uzame ukuqagela i-PIN khodi yokufinyelela ukhiye ohlakaniphile, noma uvule imoto esekela ukulawulwa kwezwi.

Ezimweni eziningi, amandla e-laser angu-50 mW anele ukwenza ukuhlasela ebangeni elingaphezu kwama-60. Ukuze kuqhutshekwe nokuhlasela, kwasetshenziswa i-laser pointer engu-$14-$18, umshayeli welaser we-Wavelength Electronics LD5CHA ongu-$339, isikhulisi somsindo se-Neoteck NTK059 esingu-$28, kanye nelensi yocingo ye-Opteka 650-1300mm engu-$200. Ukuze ugxilise ngokunembile ugongolo ebangeni elikhulu ukusuka kudivayisi, abahloli basebenzisa isibonakude njengokubona kokubona. Ezindaweni eziseduze, esikhundleni se-laser, umthombo wokukhanya okhanyayo ongagxilile, njenge flashlight Acebeam W30.

Ukuhlasela ngokuvamile akudingi ukulingiswa kwezwi lomnikazi, njengoba ukuqashelwa kwezwi kuvame ukusetshenziswa esigabeni sokufinyelela idivayisi (ukufakazela ubuqiniso ngokubiza ngokuthi “OK Google” noma “Alexa”, okungarekhodwa kusenesikhathi bese kusetshenziselwe ukumodela. isignali ngesikhathi sokuhlasela). Izici zezwi zingaphinda zenziwe mbumbulu ngamathuluzi esimanjemanje okufunda emshinini wokuhlanganisa inkulumo. Ukuze uvimbele ukuhlasela, abakhiqizi bakhuthazwa ukuthi basebenzise iziteshi zokuqinisekisa zabasebenzisi ezengeziwe, basebenzise idatha evela kumakrofoni amabili, noma bafake umgoqo phambi kwemakrofoni ovimba ukudlula okuqondile kokukhanya.
