I-TickTock prototype esebenza ngokugcwele, ehlanganisa izingxenye ezistakiwe ezihlukene
Iqembu labacwaningi evela kuNational University of Singapore kanye neYonsei University (Korea) esanda kukhishwa, abenze indlela yokuthola ukusebenza kombhobho kufihlwe kukhompuyutha ephathekayo.
Ukukhombisa ukusebenza kwe indlela esekelwe ebhodini le-Raspberry Pi 4, i-amplifier kanye ne-transceiver (SDR), i-prototype ebizwa nge-TickTock yahlanganiswa, evumela ukuthola ukwenziwa kwemakrofoni kusebenze uhlelo olungayilungele ikhompuyutha noma inhloli ukuze kulalele umsebenzisi.
Indlela yokuthola yekwentiwa ukufakwa kombhobho kuyafaneleka, njengoba, esimweni sekhamera yewebhu, umsebenzisi angavimba ukurekhoda ngokumane anamathisele ikhamera, bese ukucisha imakrofoni eyakhelwe ngaphakathi kuyinkinga futhi akucaci ukuthi isebenza nini nokuthi ingasebenzi nini.
Le ndlela isekelwe eqinisweni lokuthi uma imakrofoni isebenza, amasekhethi adlulisela amasignali ewashi kusiguquli se-analog kuya kudijithali aqala ukukhipha isignali ethile yangemuva engabanjwa futhi ihlukaniswe nomsindo obangelwa ukusebenza kwezinye izinhlelo ukuba khona kwemisebe ethile kagesi evela kumbhobho, kungaphethwa ngokuthi ukuqoshwa kuyenzeka.
Idivayisi idinga ukujwayela amamodeli ahlukene wekhompuyutha ephathekayo, njengoba imvelo yesignali ekhishiwe incike kakhulu ku-chip yomsindo esetshenzisiwe. Ukuze unqume kahle umsebenzi we-microphone, kwakudingeka futhi ukuxazulula inkinga yokuhlunga umsindo ovela kwezinye izifunda zikagesi futhi kucatshangelwa ukuguqulwa kwesignali kuye ngokuthi uxhumano.
"Okokuqala, lezi zixazululo zidinga ukuthi abasebenzisi bathembele ekusetshenzisweni kwabakhiqizi bekhompyutha ephathekayo noma izinhlelo zokusebenza, ezifakwe engcupheni abahlaseli izikhathi eziningi esikhathini esidlule noma abakhiqizi ngokwabo abangaba nonya," basho kudokhumenti yabo. "Okwesibili, lezi zixazululo zakhelwe engxenyeni encane yamadivayisi, ngakho-ke ama-laptops amaningi namuhla awanayo indlela yokuthola/ukuvimbela ukulalela."
Ekugcineni, abacwaningi bakwazi ukulungisa idivayisi yabo ukuze bathole ngokuthembekile ukusebenza kusuka kumbhobho kumamodeli angama-27 kwangu-30 yamalaptop ahloliwe enziwe ngabakwaLenovo, Fujitsu, Toshiba, Samsung, HP, Asus kanye noDell.
Amadivayisi amathathu indlela engasebenzi ngawo bekungamamodeli we-Apple MacBook ka-2014, 2017 kanye no-2019 (kwaphakanyiswa ukuthi ukuvuza kwesiginali akukwazanga ukutholwa ngenxa yekesi le-aluminium elivikelwe kanye nokusetshenziswa kwezintambo eziguquguqukayo ezimfishane).
"Ukukhishwa kuvela kuzintambo nezixhumi ezithwala amasignali wewashi ku-hardware yemakrofoni, ekugcineni ukusebenzisa i-analog-to-digital converter (ADC)," bayachaza. "I-TickTock ithwebula lokhu kuvuza ukuze ihlonze isimo sokuvula/ukuvala semakrofoni yekhompuyutha ephathekayo."
Abacwaningi nabo wazama ukulungisa indlela yezinye izigaba zamadivayisi, njengama-smartphones, amaphilisi, izipikha ezihlakaniphile namakhamera e-USB, kodwa ukusebenza kahle kwabonakala kuphansi ngokuphawulekayo: kumadivayisi angu-40 ahloliwe, kutholakale angu-21 kuphela, okuchazwa ngokusetshenziswa kwemibhobho ye-analog esikhundleni sedijithali, ezinye izifunda zokuxhuma. nama-conductor amafushane akhipha isignali ye-electromagnetic.
Umphumela ube yimpumelelo impela, ngaphandle kwe-Apple hardware.
“Yize indlela yethu isebenza kahle kumaphesenti angama-90 amalaptop ahloliwe, okuhlanganisa nawo wonke amamodeli ahloliwe avela kubathengisi abadumile abanjengoLenovo, uDell, HP, no-Asus, iTickTock yehluleka ukubona izimpawu zewashi lemakrofoni kumalaptop amathathu, wonke angama-Apple MacBooks, » Ama-brainiacs athi esihlokweni sabo.
Baqagela ukuthi kumadivayisi abengakwazi ukubonwa, kungenzeka ukuthi kungenxa yamacala e-aluminium yeMacBook kanye nezintambo ezimfishane eziguquguqukayo ezinciphisa ukuvuza kwe-EM kangangokuthi akukho siginali engatholwa.
Ngokuqondene nama-smartphone, kungase kube ngenxa ye-analog kunemakrofoni yedijithali kwamanye amamodeli efoni, ukuntuleka kwemingcele yamandla kuzingxenyekazi zekhompuyutha ezihlome ngemakrofoni exhunyiwe, njengezipikha ezihlakaniphile.
Okokugcina uma unentshisekelo yokwazi kabanzi ngakho, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
