Tekinoroji nyamukuru yo guhinduranya amajwi ni kumurika cyangwa kuyungurura umwanya.Irashobora guhindura icyerekezo cyo gufata amajwi (ni ukuvuga, ikumva icyerekezo cyamajwi) kandi ikagihindura nkuko bikenewe.Muri iki kibazo, icyerekezo cyiza nicyitegererezo cya supercardioid (ku ishusho hepfo), cyongera amajwi aturuka imbere (ni ukuvuga icyerekezo kamera ireba neza), mugihe ijwi ryumvikana rituruka mubindi byerekezo (urusaku rwinyuma).).
Ishingiro ryubu buhanga ni uko ari ngombwa gushyiraho mikoro ihuza icyerekezo cyose gishoboka: uko mikoro nyinshi kandi kure cyane, amajwi menshi ashobora kwandikwa.Iyo terefone ifite mikoro ebyiri, mubisanzwe ishyirwa hejuru no hepfo kugirango yongere intera hagati yandi;n'ibimenyetso byatoranijwe na mikoro bizaba muburyo bwiza bwo gukora supercardioid directivity.
Ishusho ibumoso ni amajwi asanzwe yafashwe;amajwi ya zoom ku ishusho iburyo afite icyerekezo cya supercardioid, cyunvikana cyane kubigenewe kandi bigabanya urusaku rwinyuma.
Igisubizo cyubu buyobozi buhanitse kiboneka hifashishijwe iyakirwa ritari ryerekezo mugushiraho inyungu zitandukanye kuri buri tsinda rya mikoro kugiti cye ahantu hatandukanye kuri terefone, hanyuma ukavuga incamake yibice bya spike kugirango uzamure amajwi wifuza kandi usenye umurongo wuruhande kugirango ugabanye Kwivanga.
Nibura, mubitekerezo.Mubyukuri, kumurika muri terefone zigendanwa bifite ibibazo byayo.Ku ruhande rumwe, terefone zigendanwa ntizishobora gukoresha tekinoroji ya mikoro ya kondenseri iboneka muri sitidiyo nini zifata amajwi, ariko igomba gukoresha transducers ya electret - miniature MEMS (micro-electro-mechanique) mikoro isaba imbaraga nke cyane zo gukora.Byongeye kandi, kugirango tunonosore ibintu byumvikana kandi ugenzure ibintu biranga ibintu byigihe gito nigihe gito bibaho hamwe no kuyungurura umwanya (nko kugoreka, gutakaza bass, nijwi rusange hamwe no kwivanga gukabije / izuru), abakora telefone ntibagomba gutekereza gusa kubishyira kuri Microphone, , igomba kwishingikiriza ku buryo bwihariye bwihariye bwo guhuza amajwi, nko kuringaniza, kumenya amajwi, n'amarembo y'urusaku (ubwabyo bishobora gutera ibihangano byumvikana).
Mu buryo bwumvikana rero, buri ruganda rufite uburyo bwihariye bwo kumurika hamwe na tekinoroji yihariye.Ibyo byavuzwe, buri buhanga butandukanye bwo kumurika bufite imbaraga, kuva imvugo-reverberation kugeza kugabanya urusaku.Nyamara, kumurika algorithms birashobora kongera byoroshye urusaku rwumuyaga mumajwi yafashwe amajwi, kandi ntabwo abantu bose bashobora cyangwa bashaka gukoresha ikirahuri cyinyongera kugirango barinde MEMS.Kandi kuki mikoro muri terefone zigendanwa zidakora byinshi?Kuberako ibyo bibangamira ibisubizo byinshyi hamwe na sensibilité ya mikoro, abayikora bakunda kwishingikiriza kuri software kugirango bagabanye urusaku n urusaku rwumuyaga.
Byongeye kandi, ntibishoboka kwigana urusaku nyarwo rwumuyaga mubidukikije bisanzwe bya acoustique muri laboratoire, kandi kugeza ubu nta gisubizo cyiza cya tekinike cyakemuka.Kubera iyo mpamvu, abayikora bagomba guteza imbere tekinoroji yihariye yo kurinda umuyaga (ishobora gukoreshwa hatitawe ku bicuruzwa bituruka ku nganda zikora) hashingiwe ku gusuzuma amajwi yafashwe.Nokia ya OZO Audio Zoom amajwi yumvikana afashijwe nubuhanga bwayo butagira umuyaga.
Kimwe no guhagarika urusaku hamwe nubuhanga bwinshi buzwi, kumurika byabanje gukorwa mubikorwa bya gisirikare.Icyiciro cya transmitter icyiciro cyakoreshejwe nka antenne ya radar mugihe cyintambara ya kabiri yisi yose, kandi uyumunsi irakoreshwa mubintu byose uhereye kumashusho yubuvuzi kugeza kwizihiza umuziki.Kubijyanye na mikoro yicyiciro, bahimbwe muri 70 na John Billingsley (oya, ntabwo ari umukinnyi wakinnye na Dr. Volash muri Star Trek: Enterprises) na Roger Kinns.Nubwo imikorere yikoranabuhanga muri terefone igendanwa itigeze itera imbere cyane mu myaka icumi ishize, telefone zimwe zirenze urugero, zimwe zifite za mikoro nyinshi, ndetse zimwe zifite chipeti zikomeye.Terefone igendanwa ubwayo ifite urwego rwisumbuyeho, bigatuma tekinoroji yo guhinduranya amajwi ikora neza mubikorwa bitandukanye byamajwi.
Mu mpapuro za N. van Wijngaarden na EH Wouters “Kuzamura amajwi ukoresheje urumuri ukoresheje telefoni zigendanwa” igira iti: “Turatekereza ko ibihugu by’ubugenzuzi (cyangwa ibigo) bishobora gukoresha uburyo bwihariye bwo kumurika kugira ngo butasi abaturage bose .Ariko kugeza aho abantu benshi babikurikirana. , ni bangahe sisitemu yo kumurika ya terefone ishobora kugira?.Ikoranabuhanga ryihariye rimurika kuri terefone zigendanwa riracyari ahantu hatarondoreka, kandi kubura tekinoroji yikiragi hamwe nuburyo bwo guhuza ibitekerezo bitagabanya amahirwe yo gutega amatwi rwihishwa.
