Iyo huru tekinoroji yeaudio zoom ndeyekupenya kana kusefa kwenzvimbo.Inogona kushandura mafambiro ekurekodha odhiyo (kureva kuti, inonzwa kwainoenda kunobva ruzha) uye kuigadzirisa sezvinodiwa.Muchiitiko ichi, iyo yakakwana kutungamira ndeye supercardioid pateni (inoratidzwa pazasi), iyo inosimudzira ruzha runobva kumberi (kureva, gwara rakatariswa nekamera zvakananga), uku ichidzikamisa ruzha runobva kune mamwe mativi (kumashure ruzha).)
Nheyo yeiyi tekinoroji ndeyekuti zvinodikanwa kumisikidza maikorofoni omnidirectional zvakanyanya sezvinobvira: iyo yakawanda maikorofoni uye kure kure, iyo yakawanda inzwi inogona kurekodhwa.Kana foni iine maikorofoni maviri, anowanzoiswa kumusoro uye pasi kuti awedzere kureba pakati peumwe neumwe;uye masaini anotorwa nemakrofoni achave ari musanganiswa wakanakisa kugadzira supercardioid directivity.
Mufananidzo uri kuruboshwe ndeyekurekodhwa kwakajairika;iyo odhiyo zoom pamufananidzo kurudyi ine supercardioid dhairekitori, iyo inonyanya kunzwisiswa kune inonangwa sosi uye inoderedza kumashure ruzha.
Mhedzisiro yeiyi yakakwira dhairekitori inowanikwa uchishandisa iyo isiri-directional inogamuchira nekuisa akasiyana mibairo kune yega yega maikorofoni munzvimbo dzakasiyana siyana parunhare, wobva wapfupisa zvikamu zvemaspikes kuti uwedzere ruzha rwaunoda uye kuparadza mafungu epadivi kuderedza. off-axis kupindira.
Zvirinani, mudzidziso.Muchokwadi, kupenya mumafoni ane matambudziko ako.Kune rumwe rutivi, nharembozha haigone kushandisa tekinoroji yemakrofoni yecondenser inowanikwa mumasitudiyo makuru ekurekodha, asi inofanira kushandisa electret transducers-miniature MEMS (micro-electro-mechanical systems) maikorofoni inoda simba shoma shoma kuti rishande.Uyezve, kuitira kukwidziridza kungwara uye kudzora hunhu hunoonekwa uye hwenguva pfupi hunoitika nekusefa kwenzvimbo (sekukanganisa, kurasikirwa kwebass, uye ruzha rwese nekukanganisika kwakakomba kwechikamu / nasality), vagadziri ve smartphone havafanire kungofunga nekungwarira maikorofoni kuiswa, zvakare. , inofanirwa kuvimba neyayo yakasarudzika musanganiswa wemanzwi, seakaenzana, kuona inzwi, uye magedhi eruzha (izvo pachazvo zvinogona kukonzera zvinonzwika).
Saka zvine musoro, mugadziri wega wega ane yake yakasarudzika nzira yekushongedza yakasanganiswa nehunyanzvi tekinoroji.Izvozvo zvakati, imwe neimwe yakasiyana-siyana yekugadzira bhenekeri ine simba rayo, kubva pakutaura de-reverberation kusvika pakuderedza ruzha.Nekudaro, maalgorithms ekuvheneka anogona kukwidziridza ruzha rwemhepo zviri nyore muodhiyo yakarekodhwa, uye havasi vese vanogona kana kuda kushandisa imwe windshield kuchengetedza MEMS.Uye nei maikorofoni ari mumafoni emafoni asingaite zvakawanda kugadzirisa?Nekuti izvo zvinokanganisa mafambisirwo emhinduro uye kunzwa kwemakrofoni, vagadziri vanowanzovimba nesoftware kuderedza ruzha uye ruzha rwemhepo.
Pamusoro pezvo, hazvibviri kutevedzera ruzha rwemhepo chaiyo munzvimbo yeacoustic yakasikwa pasi pemamiriro erabhoritari, uye kusvika parizvino hapachina yakanaka tekinoroji mhinduro yekugadzirisa nayo.Nekuda kweizvozvo, vagadziri vanofanirwa kugadzira yakasarudzika dhijitari yekudzivirira mhepo tekinoroji (iyo inogona kushandiswa zvisinei neyakagadzirwa dhizaini dhizaini) zvichienderana nekuongororwa kweakarekodhwa odhiyo.Nokia's OZO Audio Zoom inorekodha ruzha ichibatsirwa nehunyanzvi hwayo hwekudzivirira mhepo.
Kufanana nekudzima ruzha uye mamwe akawanda hunyanzvi hunyanzvi, kugadzirwa kwebeamform kwakatanga kugadzirwa nekuda kwemauto.Phased transmitter arrays akashandiswa se radar antennas munguva yeHondo Yenyika II, uye nhasi anoshandiswa kune zvese kubva pakufungidzira kwekurapa kusvika kumhemberero dzemimhanzi.Kana zviri zvemakrofoni arrays akapatsanurwa, akagadzirwa mu70s naJohn Billingsley (kwete, kwete mutambi akaridza Dr. Volash muStar Trek: Enterprise) naRoger Kinns.Kunyangwe mashandiro eiyi tekinoroji muma smartphones asina kuvandudzwa zvakanyanya mumakore gumi apfuura, mamwe mawoko anowandisa, mamwe ane akawanda seti emakrofoni, uye mamwe anotove ane simba rakawanda chipsets.Iyo mbozha nhare pachayo ine nhanho yepamusoro, ichiita tekinoroji yezoom tekinoroji inoshanda mumhando dzakasiyana dzekuteerera.
Mupepa raN. van Wijngaarden neEH Wouters rinonzi “Enhancing Sound by Beamforming Using Smartphones” rinoti: “Zvinouya mupfungwa kuti nyika dzinoongorora (kana kuti makambani) dzingashandisa nzira dzakati dzokugadzira mwenje kuti vasore vagari vose .Asi kusvika pamwero wokuongororwa kwevanhu vakawanda. , inokanganisa sei smartphone's beamforming system ine?[…] Muchifungidziro, kana tekinoroji ikawedzera kukura, inogona kuve chombo mune inotarisisa state arsenal, asi Izvo zvichiri kure kure.Iyo chaiyo beamforming tekinoroji pamafoni emafoni ichiri dunhu risingaverengeki, uye kushomeka kwechimumumu tekinoroji uye zvisingatarisike nzira dzekubatanidza zvinoderedza mukana wekuteerera pakavanda.
