zomvera

Tekinoloje yayikulu yowonera ma audio ndikuwunikira kapena kusefa kwapakati.Ikhoza kusintha njira yojambulira mawu (ndiko kuti, imamva komwe akuchokera) ndikuisintha ngati ikufunika.Pamenepa, njira yabwino kwambiri ndi mawonekedwe a supercardioid (chithunzi m'munsimu), chomwe chimapangitsa kuti phokoso likhale lochokera kutsogolo (ndiko kuti, mbali yomwe kamera ikuyang'ana molunjika), pamene phokoso lochepetsetsa likuchokera mbali zina (phokoso lakumbuyo).).

Maziko a teknolojiyi ndikuti ndikofunikira kukhazikitsa maikolofoni ya omnidirectional momwe mungathere: ma maikolofoni ochulukirapo komanso akutali, phokoso lochulukirapo limatha kulembedwa.Pamene foni ili ndi maikolofoni awiri, nthawi zambiri amayikidwa pamwamba ndi pansi kuti awonjezere mtunda pakati pa wina ndi mzake;ndipo zizindikiro zotengedwa ndi maikolofoni zidzakhala zogwirizana kwambiri kuti apange supercardioid directivity.

Chithunzi chakumanzere ndi chojambulira chojambulira;makulitsidwe omvera pa chithunzi kumanja ali ndi supercardioid directivity, yomwe imakhudzidwa kwambiri ndi gwero la chandamale ndikuchepetsa phokoso lakumbuyo.

Zotsatira za kuwongolera kwakukulu kumeneku zimapezedwa pogwiritsa ntchito cholandirira chosalozera pokhazikitsa zopindulitsa zosiyanasiyana pagulu lililonse la maikolofoni pagulu pazigawo zosiyanasiyana pafoni, kenako ndikuwerengera magawo a ma spikes kuti apititse patsogolo phokoso lomwe mukufuna ndikuwononga mafunde am'mbali kuti muchepetse. kusokoneza kwa off-axis.

Osachepera, m'malingaliro.M'malo mwake, kupanga bwino mu mafoni a m'manja kuli ndi zovuta zake.Kumbali imodzi, mafoni a m'manja sangathe kugwiritsa ntchito makina opangira maikolofoni a condenser omwe amapezeka m'ma studio akuluakulu ojambulira, koma ayenera kugwiritsa ntchito electret transducers-miniature MEMS (micro-electro-mechanical systems) ma microphone omwe amafuna mphamvu zochepa kwambiri kuti agwire ntchito.Kuphatikiza apo, kuti muthe kumveketsa bwino ndikuwongolera zowoneka bwino komanso zakale zomwe zimachitika ndi kusefa kwapamalo (monga kupotoza, kutayika kwa bass, ndi kumveka kwathunthu ndi kusokonezedwa kwakukulu kwa gawo / nasality), opanga mafoni sayenera kungoganizira mozama maikolofoni, nawonso. , iyenera kudalira kuphatikizika kwake kwapadera kwa zida zamawu, monga zofananira, kuzindikira mawu, ndi zipata zaphokoso (zomwe zimatha kuyambitsa zida zomveka).

Chifukwa chake, zomveka, wopanga aliyense ali ndi njira yakeyake yopangira ma beamforming kuphatikiza ndiukadaulo wa eni.Izi zati, njira iliyonse yowunikira imakhala ndi mphamvu zake, kuyambira kubwereza mawu mpaka kuchepetsa phokoso.Komabe, ma aligorivimu owoneka bwino amatha kukulitsa phokoso lamphepo mumawu ojambulidwa, ndipo si aliyense amene angathe kapena kufuna kugwiritsa ntchito chowonjezera chakutsogolo kuteteza MEMS.Ndipo chifukwa chiyani ma maikolofoni omwe ali m'mafoni am'manja samachita zambiri?Chifukwa izi zimasokoneza kuyankha pafupipafupi komanso kukhudzidwa kwa maikolofoni, opanga amakonda kudalira mapulogalamu kuti achepetse phokoso ndi phokoso lamphepo.

Kuphatikiza apo, ndizosatheka kutsanzira phokoso lenileni la mphepo m'malo omvera achilengedwe pansi pamikhalidwe ya labotale, ndipo mpaka pano palibe njira yabwino yothetsera vutoli.Zotsatira zake, opanga akuyenera kupanga matekinoloje apadera a digito oteteza mphepo (omwe angagwiritsidwe ntchito mosasamala kanthu za malire a kapangidwe ka mafakitale) potengera kuwunika kwa mawu ojambulidwa.Nokia OZO Audio Zoom imalemba mawu mothandizidwa ndi ukadaulo wake woletsa mphepo.

Monga kuletsa phokoso ndi njira zina zambiri zodziwika bwino, kuwala kowala kudapangidwira zida zankhondo.Ma transmitter ophatikizika adagwiritsidwa ntchito ngati tinyanga ta radar pa Nkhondo Yachiwiri Yapadziko Lonse, ndipo masiku ano amagwiritsidwa ntchito pachilichonse kuyambira kujambula zamankhwala mpaka zikondwerero zanyimbo.Ponena za ma maikolofoni apakati, adapangidwa mu 70s ndi John Billingsley (ayi, osati wosewera yemwe adasewera Dr. Volash mu Star Trek: Enterprise) ndi Roger Kinns.Ngakhale kuti ukadaulo uwu mu mafoni a m'manja sunayende bwino kwambiri pazaka khumi zapitazi, zida zina zam'manja ndizokulirapo, zina zimakhala ndi ma maikolofoni angapo, ndipo zina zimakhala ndi ma chipset amphamvu kwambiri.Foni yam'manja palokha imakhala ndi mulingo wapamwamba kwambiri, zomwe zimapangitsa kuti ukadaulo wa zoom zomvera ukhale wogwira mtima pamapulogalamu osiyanasiyana amawu.

M’nkhani ya N. van Wijngaarden ndi EH Wouters yakuti “Kupititsa Patsogolo Phokoso mwa Kuwala Pogwiritsa Ntchito Mafoni Amakono” imati: “Timakumbukira kuti mayiko (kapena makampani) angagwiritse ntchito njira zodziwira kuti akazonde anthu onse. , Kodi mawonekedwe a foni yam'manja angakhudze bwanji?[…] Mwachidziwitso, ngati ukadaulo umakhala wokhwima kwambiri, ukhoza kukhala chida mu zida zachitetezo cha boma, koma Akadali patali.Ukadaulo wapa foni yam'manja ukadali wosadziwika, ndipo kusowa kwaukadaulo wosalankhula komanso njira zolumikizirana zosawoneka bwino zimachepetsa mwayi womvera mobisa.
