Raspberry Pi 4 inali maziko opangira chipangizo chomwe chimatha kuzindikira kutsegulidwa kwa maikolofoni mu laputopu

Tiktok-chipangizo chomwe chimalola kuzindikira pomwe maikolofoni ya laputopu yatsegulidwa

pulojekiti ya TickTock yogwira ntchito mokwanira, yopangidwa ndi zinthu zosiyanasiyana

Gulu la ofufuza kuchokera ku National University of Singapore ndi Yonsei University (Korea) posachedwapa, omwe apanga njira yodziwira kutsegulidwa kwa maikolofoni zobisika mu laputopu.

Kuwonetsa ntchito ya njira yotengera Raspberry Pi 4 board, amplifier ndi transceiver (SDR), prototype yotchedwa TickTock idasonkhanitsidwa, yomwe imalola kuzindikira kutsegulira kwa maikolofoni ndi pulogalamu yaumbanda kapena mapulogalamu aukazitape kuti amvetsere wogwiritsa ntchito.

Njira yodziwira yokha kuphatikiza maikolofoni ndizofunika, popeza, pakakhala ma webukamu, wogwiritsa ntchito amatha kuletsa kujambula pongokakamira kamera, ndiye kuzimitsa maikolofoni yomangidwa ndizovuta ndipo sichidziwika nthawi yomwe ikugwira ntchito komanso nthawi yomwe siili.

Njirayi imachokera pa mfundo yakuti pamene maikolofoni akugwira ntchito, maulendo omwe amatumiza zizindikiro za wotchi ku analogi kupita ku digito yosinthira digito amayamba kutulutsa chizindikiro cham'mbuyo chomwe chingathe kugwidwa ndikulekanitsidwa ndi phokoso lomwe limabwera chifukwa cha machitidwe ena. kukhalapo kwa ma radiation enieni a electromagnetic kuchokera pa maikolofoni, tinganene kuti kujambula kukuchitika.

Chipangizocho chimafuna kusintha kwamitundu yosiyanasiyana ya laputopu, monga momwe chizindikiro chomwe chimatulutsira chimadalira kwambiri kachipangizo kamene kamagwiritsidwa ntchito. Kuti mudziwe bwino ntchito ya maikolofoni, kunali koyeneranso kuthetsa vuto la kusefa phokoso kuchokera kumadera ena amagetsi ndikuganizira kusintha kwa chizindikirocho malinga ndi kugwirizana.

"Choyamba, mayankhowa amafuna kuti ogwiritsa ntchito akhulupirire kukhazikitsa kapena kugwiritsa ntchito makina a laputopu, omwe asokonezedwa ndi owukira kangapo m'mbuyomu kapena omwe opanga nawonso angakhale oyipa," akutero m'chikalata chawo. "Chachiwiri, mayankhowa amapangidwa m'kagawo kakang'ono ka zida, kotero ma laputopu ambiri masiku ano alibe njira yodziwira / kuletsa kumvetsera."

Pamapeto pake, ochita kafukufukuwo adatha kusintha chipangizo chawo kuti azindikire modalirika akutsegula kuchokera pa maikolofoni m'mitundu 27 mwa 30 Ma laputopu oyesedwa opangidwa ndi Lenovo, Fujitsu, Toshiba, Samsung, HP, Asus ndi Dell.

Zida zitatu zomwe njirayo sizinagwire ntchito ndi mitundu ya 2014, 2017 ndi 2019 Apple MacBook (zinanenedwa kuti kutayikira kwa siginecha sikunadziwike chifukwa cha mlandu wa aluminiyamu wotetezedwa komanso kugwiritsa ntchito zingwe zazifupi zosinthira).

"Kutulukaku kumachokera ku zingwe ndi zolumikizira zomwe zimanyamula mawotchi kupita ku ma maikolofoni, kuti agwiritse ntchito chosinthira chake cha analog-to-digital (ADC)," akufotokoza. "TickTock imajambula kutayikiraku kuti muwone momwe maikolofoni ya laputopu ilili kapena kuyimitsa."

Ofufuza nawonso adayesa kusintha njira yamagulu ena a zida, monga mafoni a m'manja, mapiritsi, oyankhula anzeru ndi makamera a USB, koma magwiridwe antchito adakhala otsika kwambiri: mwa zida 40 zomwe zidayesedwa, 21 zokha zidapezeka, zomwe zimafotokozedwa ndikugwiritsa ntchito maikolofoni a analogi m'malo mwa digito, mabwalo ena olumikizirana. ndi ma kondakitala achifupi omwe amatulutsa chizindikiro cha electromagnetic.

Zotsatira zake zinali zopambana, kupatula Apple hardware.

"Ngakhale njira yathu imagwira ntchito bwino pa 90 peresenti ya ma laputopu oyesedwa, kuphatikiza mitundu yonse yoyesedwa kuchokera kwa ogulitsa otchuka monga Lenovo, Dell, HP, ndi Asus, TickTock imalephera kuzindikira mawotchi a maikolofoni pama laputopu atatu, onse omwe ndi Apple MacBook, " Amatero a brainics m'nkhani yawo.

Amalingalira kuti pazida zomwe zinali zosatheka kuzizindikira, zitha kukhala chifukwa cha milandu ya aluminiyamu ya MacBook ndi zingwe zazifupi zopindika zomwe zimalepheretsa kutayikira kwa EM kotero kuti palibe chizindikiro chomwe chingadziwike.

Ponena za mafoni a m'manja, zitha kukhala chifukwa cha ma analogi m'malo mwa ma maikolofoni a digito pama foni ena, kusowa kwamagetsi pazida zolumikizidwa ndi maikolofoni, monga olankhula anzeru.

Mapeto ngati mukufuna kudziwa zambiri za izi, mutha kuwona zambiri Mu ulalo wotsatira.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
