Sixoxa ngesixhobo sokuhambisa isandi esisiya kwicala eliya ngakulo. Isebenzisa "iilensi ze-acoustic" ezikhethekileyo, kwaye umgaqo wayo wokusebenza ufana nenkqubo yekhamera yekhamera.
Kwiyantlukwano ye-acoustic metamataries
Ngokwahlukileyo , iipropathi ze-acoustic ezixhomekeke kulwakhiwo lwangaphakathi, iinjineli kunye nezazinzulu zisebenze ixesha elide. Ngokomzekelo, ngo-2015, iingcali zefiziksi zilawula Kumshicileli we-3D, "i-acoustic diode" - lijelo le-cylindrical elivumela umoya ukuba udlule, kodwa libonisa ngokupheleleyo isandi esivela kwicala elinye kuphela.
Kwakhona kulo nyaka, iinjineli zaseMelika zenze umsesane okhethekileyo ovimba ukuya kuthi ga kwi-94% yengxolo. Umgaqo wayo wokusebenza usekelwe , xa amandla amaza amabini aphazamisayo asasazwa nge-asymmetrically. Sathetha ngakumbi ngesi sixhobo kwenye yethu .
Ekuqaleni kuka-Agasti, olunye uphuhliso lomsindo lwaziwa. Iinjineli ezivela kwiYunivesithi yaseSussex iprototype yesixhobo, usebenzisa i-metamatadium ezimbini ("i-acoustic lens") kunye nekhamera yevidiyo, ikuvumela ukuba ugxininise isandi kumntu othile. Esi sixhobo sasibizwa ngokuba “yiprojektha yesandisi-lizwi.”
ntoni lo msebenzi
Ngaphambi komthombo wesandi (isithethi somsindo) kukho "iilensi ze-acoustic" ezimbini. Ezi lens ziyi-3D eprintiweyo yeplastiki ipleyiti enenani elikhulu lemingxuma. Unokubona ukuba ezi "lensi" zijongeka njani kwiphepha lokuqala (kufuneka uvule okubhaliweyo okupheleleyo koxwebhu).
Umngxuma ngamnye "kwi-audio lens" inesimo esikhethekileyo - umzekelo, izitenxo kwiindonga zangaphakathi. Xa isandi sidlula kule mingxuma, sitshintsha isigaba saso. Ekubeni umgama phakathi kwee-"acoustic lens" ezimbini unokwahluka usebenzisa ii-motor zombane, kuba lula ukuqondisa isandi kwindawo enye. Inkqubo ikhumbuza ukugxila kwi-optics yekhamera.
Ukugxininisa kuyazenzekela. Oku kwenziwa kusetyenziswa ikhamera yevidiyo (ixabisa malunga ne-12 yeedola) kunye ne-algorithm yesoftware ekhethekileyo. Ikhumbula ubuso bomntu kwividiyo kwaye ilandele intshukumo yakhe kwisakhelo. Emva koko, inkqubo ibala umgama ohambelanayo kwaye itshintshe ubude beprojekthi yeprojekti ngokufanelekileyo.
Iza kusetyenziswa phi?
Abaphuhlisi ukuba kwixesha elizayo inkqubo inokutshintsha i-headphones - izixhobo ziya kusasaza isandi ukusuka kude ngqo kwiindlebe zabasebenzisi. Enye indawo enokwenzeka yesicelo ziimyuziyam kunye nemiboniso. Iindwendwe ziya kukwazi ukumamela iintetho ezivela kwizikhokelo ze-elektroniki ngaphandle kokuphazamisa abanye. Ewe, asinakukwazi ukusilela ukuqaphela indawo yentengiso - kuya kwenzeka ukwazisa iindwendwe zevenkile malunga neemeko zokunyuswa komntu.
Kodwa iinjineli kusafuneka zisombulule iingxaki ezininzi - ukuza kuthi ga ngoku iprojektha yomsindo iyakwazi ukusebenza kuluhlu olulinganiselweyo lwamaza. Ngokukodwa, idlala kuphela amanqaku G (G) ukuya kuD (D) kwi-octave yesithathu neyesixhenxe.
Abahlali beHacker News nabo iingxaki zomthetho ezinokubakho. Ngokukodwa, kuya kufuneka ukulawula ukuba ngubani na phantsi kweemeko eziya kukwazi ukufumana imiyalezo yentengiso yomntu. Ngaphandle koko, isiphithiphithi siya kuqala kwizakhiwo zamaziko okuthenga. Njengoko abaphuhlisi be "audio projektha" bathi, lo mbandela uya kusonjululwa ngokuyinxenye yinkqubo yokuqaphela ubuso. Iya kugqiba ukuba ngaba umntu uvumile na ukufumana ezo zibhengezo okanye hayi.
Kwimeko nayiphi na into, akukho ntetho malunga nokuphunyezwa okusebenzayo kweteknoloji "kwintsimi".
Ezinye iindlela zokuhambisa isandi esibhekisayo
Ekuqaleni konyaka, iinjineli ezivela kwi-MIT zaphuhlisa itekhnoloji yokuhambisa isandi solwalathiso usebenzisa i-laser ene-wavelength ye-1900 nm. Ayinabungozi kwiretina yomntu. Isandi sisasazwa kusetyenziswa into ebizwa xa umphunga wamanzi osemoyeni ufunxa amandla okukhanya. Ngenxa yoko, ukunyuka kwendawo yoxinzelelo kwenzeka kwindawo kwindawo. Umntu unokukubona ukushukuma komoya okubangelwa “ngendlebe ehamba ze.”
Iingcali ezivela kwiSebe lezoKhuselo lase-US ziphuhlisa iteknoloji efanayo. Besebenzisa i-laser ye-femtosecond, benza ibhola yeplasma emoyeni, kwaye babangele ukungcangcazela kwesandi kuyo besebenzisa enye i-nanolaser. Enyanisweni, ngale ndlela unokwenza kuphela ukugquma kunye nengxolo engathandekiyo, efana nokukhala kwe-siren.
Ukuza kuthi ga ngoku, obu buchwepheshe abushiyanga ibhubhoratri, kodwa ii-analogues zabo ziqala "ukungena" kwizixhobo zabasebenzisi. Kunyaka ophelileyo, uNoveto sele ekhona isithethi somsindo esenza "i-headphones ebonakalayo" entloko yomntu usebenzisa amaza e-ultrasonic. Ke ngoko, ukwamkelwa okubanzi kwetekhnoloji yesandi esikhokelayo ngumcimbi wexesha kuphela.
