Sikukhethele izinto ezisetshenziswayo eziphawuleka kakhulu “kumhlaba wethu we-Hi-Fi”: ukusuka ku-acoustic levitation kuya ekudluliselweni kwemali kusetshenziswa umsindo kanye nokuvala umsindo okucishe kube amaphesenti ayikhulu.
Uma lezi zihloko ezithakazelisayo kuwe, sikumema ekati.

- . Sikhuluma ngokuthi imigwaqo "izwakala" kanjani emazweni ahlukene. Isimiso sokusebenza lapha simi kanje: ama-grooves of a deep deep ayenziwa emgwaqeni, atholakala ebangeni elihlukile komunye nomunye. Futhi uma uhamba ngesivinini esifanele, ungawuzwa umculo. Isifaniso esiseduze kakhulu esivela emhlabeni wobuchwepheshe bomsindo ukudlala i-vinyl. Kuyathakazelisa ukuthi ukumbozwa okunjalo kwahlolwa eDenmark emuva ekuqaleni kwawo-90s; okunye ukuhlola okwaziwayo kwenzeka eSouth Korea naseCalifornia.
- . Sonke siyizwile inkulumo ethi: “Ukuthuthukisa izinga lesevisi, zonke izingxoxo ziyarekhodwa.” Manje lokhu akuphathelene nezikhungo zezingcingo kuphela. Ngakho, i-Walmart ifake amasistimu omsindo eduze namarejista emali aqopha ukuxhumana phakathi kwabasebenzi namakhasimende. Lawa marekhodi abe esehlaziywa futhi ahlolwe. Ezitolo, kukhona nabasizi bezwi: uku-oda ikhofi nge-Alexa, ukuthenga igrosa ngomsizi we-Google. Ngamafuphi, “ikusasa selifikile.”
- . Ubuwazi ukuthi ungakwazi ukulwa ne-aerophobia ngosizo lwama-headphone anephunga elimnandi? I-"jack" evamile ingashintshwa ibe yi-thermometer, i-oscilloscope kanye nesiteshi sonke sesimo sezulu esiphathwayo. Futhi ngosizo lwamaza omsindo wemvamisa ethile kanye nobukhulu, izinto ezincane zingaphakanyiswa emoyeni. Ngaphezu kwamagajethi nocwaningo, sixoxa ngokusetshenziswa kobuchwepheshe bomsindo kwezempilo - sikhuluma "ngomtshingo wamaphaphu", osiza ukuqeda ezinye izifo zisebenzisa amaza aphansi.
- . Ake sithi ngokushesha lokhu akuwona ubuchwepheshe obusha, kodwa indlela ehlukile yokwethula izinto. Ubuchwepheshe buhlanganiswe nesakhiwo sezindlebe zethu kanye nalokho okubizwa ngokuthi umsebenzi wokudlulisa ikhanda, owaziwa nangokuthi i-HRTF. Kodwa ukusabela kumculo onjalo (kukhona izibonelo esihlokweni) kuyindida - phela, i-HRTF ingumuntu ngamunye.
- . Le nto ikhuluma ngobuchwepheshe obukuvumela ukuthi uqophe umsindo ukude. Okuncane mayelana nemakrofoni ye-laser, ubuchwepheshe be-NASA kanye ne-antenna yophondo. Futhi nge-dessert - imakrofoni ebonakalayo. Ikuvumela ukuthi ubuyisele umsindo ngokusekelwe kumavidiyo wevidiyo. Abadali bobuchwepheshe bathi kuze kube manje izinga lomsindo onjalo lishiya okuningi, kodwa basebenza kulo.
- . Kulesi sihloko sifunda ngohlelo lokukhokha olusetshenziswa i-Google e-India. Ubuchwepheshe bokudlulisa idatha kusetshenziswa umsindo ngokwawo akuwona obusha - i-IBM ithuthukise into efanayo emuva kuma-40s wekhulu leminyaka elidlule. Nokho, le ndlela isezingeni elifanayo ne-Bluetooth, i-NFC nezinye izindlela zokuxhumana ngaphandle kokuthinta. Esihlokweni sizoqonda ukuthi konke kusebenza kanjani, ukuthi ukuphepha kwedatha kuqinisekiswa kanjani, yiziphi izinzuzo (i-spoiler: kuze kube manje ihlobene ngokukhethekile nemininingwane yaseNdiya) kanye nokubi.
- . Ake sibheke ukuthi iyini "i-vinyl ethuthukisiwe". Izigaba zokukhiqiza zisuka ekuguquleni ifayela elilalelwayo libe “imephu ye-topographical-dimensional three-dimensional” yerekhodi lesikhathi esizayo ukuya ekucindezeleni. Siphinde sixoxe ngezinye izindlela eseziqala ukusetshenziswa ngenxa yesidingo esikhulayo sama-vinyl.
- . Mayelana nephupho lawo wonke umuntu ozonda intsha enezikhulumi. Futhi indlela yokwenza umsindo ukuthi, ekamelweni elinabantu abaningana, lizozwakala ngomunye wabo kuphela. Le nkinga yaqala ukuxazululwa emuva kuma-80s, kodwa ezingeni lakudala. Umlaleli kwakucatshangwa ukuthi umi endaweni eyodwa. Futhi namuhla kwa-Israyeli baye bahlakulela isistimu ye-acoustic enezinzwa ezilandelela indawo yekhanda lomlaleli. Ubuchwepheshe busenamaphutha, kodwa buyaqedwa, futhi kunezindawo eziningi zokusetshenziswa - kusukela kumamyuziyamu anemihlahlandlela yomsindo kuya emashalofini anemishini yomsindo ezitolo. Abaningi bathemba ukuthi maduze ngeke kudingeke balalele enye i-Feduk ebhasini nesixuku sentsha, kodwa wonke umuntu unendlela yakhe yokulalela.

- . Sikhuluma ngokuthuthukiswa kobuchwepheshe be-acoustic tweezers, obukuvumela ukuthi uphakamisele izinto ezincane emoyeni usebenzisa i-ultrasound. Uma ngaphambili kwakungenzeka ukuphakamisa into eyodwa kuphela ngale ndlela, le ndlela ikuvumela ukuthi usebenze nabaningana ngesikhathi esisodwa futhi ulawule ukunyakaza kwabo. Kunezindawo eziningi zokufaka isicelo - kusukela kwezokwelapha kuya kwezokuzijabulisa nokudala ama-hologram amathathu-dimensional. Lesi sihloko siqukethe ulwazi mayelana nentuthuko efanayo: kusukela ekunyatheliseni kwe-acoustic kuya ekudalweni kwamasimu e-ultrasonic of shapes ahlukahlukene.
- . Indandatho ye-3D ephrintiwe isebenza kahle kakhulu kunezinhlelo zesimanje zokuvikela umsindo. Isimiso sokusebenza sisekelwe ku-Fano resonance - ngenxa yokuma okukhethekile kwendandatho, amandla amagagasi amabili ngesikhathi sokuphazanyiswa asatshalaliswa ngokulinganayo. Ngesinye isikhathi ingcindezi ye-acoustic ifinyelela amanani aphezulu, futhi kwenye yehla cishe ku-zero. I-athikili iqukethe ividiyo ye-prototype kanye nengxoxo yobuchwepheshe.
Futhi kubhulogi yethu ku-Habré sikhuluma ngamafomethi omsindo asekhohliwe:
