Ithimba labacwaningi abavela ku-National University of Singapore kanye ne-Yonsei University (Korea) lenze indlela yokuthola ukusebenza kwemakrofoni efihliwe kukhompuyutha ephathekayo. Ukukhombisa ukusebenza kwendlela, i-prototype ebizwa ngokuthi i-TickTock yahlanganiswa ngokusekelwe ebhodini le-Raspberry Pi 4, i-amplifier kanye ne-transceiver ehlelekayo (SDR), ekuvumela ukuthi ubone ukusebenza kombhobho ngonya noma nge-spyware ukuze ulalele umsebenzisi. Isu lokubona ngokuthula ukuthi imakrofoni ivuliwe iyasebenza ngoba, uma esimweni sekhamera yewebhu umsebenzisi angavimba ukurekhodwa ngokumboza ikhamera, khona-ke ukukhubaza imakrofoni eyakhelwe ngaphakathi kuyinkinga futhi akucaci ukuthi kwenzeka nini. iyasebenza futhi uma ingasebenzi.
Indlela isekelwe eqinisweni lokuthi lapho imakrofoni isebenza, amasekhethi adlulisela amasignali ewashi kusiguquli se-analog-to-digital aqala ukukhipha isignali ethile yangemuva engatholwa futhi ihlukaniswe nomsindo obangelwa ukusebenza kwezinye izinhlelo. Ngokusekelwe ekubeni khona kwemisebe ye-electromagnetic eqondene nemakrofoni, umuntu angaphetha ngokuthi kuyarekhodwa.
Idivayisi idinga ukujwayela amamodeli ahlukene encwajana, njengoba imvelo yesiginali ekhishiwe incike kakhulu ku-chip yomsindo esetshenzisiwe. Ukuze unqume kahle umsebenzi wemakrofoni, kwakudingeka futhi ukuxazulula inkinga yokuhlunga umsindo ovela kwamanye amasekhethi kagesi futhi ucabangele ukuguqulwa kwesignali kuye ngoxhumo.
Ngenxa yalokho, abacwaningi bakwazi ukulungisa idivayisi yabo ukuze bathole ngokuthembekile ukuthi imakrofoni ivuliwe yini imodeli ye-laptop engu-27 kwezingu-30 ezihloliwe ezenziwe yiLenovo, Fujitsu, Toshiba, Samsung, HP, Asus kanye noDell. Amadivayisi amathathu lapho le ndlela ingasebenzi khona bekungamamodeli we-Apple MacBook 2014, 2017 kanye no-2019 (kucatshangwa ukuthi ukuvuza kwesignali akukwazanga ukutholwa ngenxa yekesi le-aluminium elivikelayo kanye nokusetshenziswa kwezintambo ezimfishane eziguquguqukayo).
Abacwaningi baphinde bazama ukulungisa indlela yezinye izigaba zamadivayisi, njengama-smartphones, amaphilisi, izipikha ezihlakaniphile namakhamera e-USB, kodwa ukusebenza kahle kwakuphansi ngokuphawulekayo - kumadivayisi angu-40 ahloliwe, ukutholwa kwasungulwa ku-21 kuphela, okuchazwa ngu. ukusetshenziswa kwemibhobho ye-analogi esikhundleni sedijithali, ezinye izixhumanisi zamasekhethi kanye namakhondatha amafushane akhipha isignali ye-electromagnetic.
