Mahedifoni oletsa phokosondiukadaulo wapamwamba wamawu womwe umachepetsa kwambiri phokoso losafunikira lozungulira, kupatsa ogwiritsa ntchito kumvetsera mozama. Amakwaniritsa izi kudzera munjira yotchedwa Active Noise Control (ANC), yomwe imaphatikizapo zida zamakono zamagetsi zomwe zimagwirira ntchito limodzi kuti zithetse mawu akunja.
Momwe ANC Technology Imagwirira Ntchito
Kuzindikira Phokoso: Maikolofoni ang'onoang'ono omwe ali m'makutu amajambula phokoso lakunja munthawi yeniyeni.
Kusanthula Zizindikiro: Purosesa ya digito ya onboard (DSP) imasanthula ma frequency ndi matalikidwe a phokoso.
Anti-Noise Generation: Dongosololi limapanga mafunde opingasa (otsutsa-phokoso) omwe ali ofanana ndi matalikidwe koma madigiri a 180 kunja kwa gawo ndi phokoso lomwe likubwera.
Kusokoneza Kowononga: Pamene mafunde odana ndi phokoso akuphatikizana ndi phokoso loyambirira, amathetsana wina ndi mzake mwa kusokoneza kowononga.
Koyera Zotulutsa Zomvera: Wogwiritsa amangomva zomvera zomwe akufuna (monga nyimbo kapenakuyimba mawu) yokhala ndi zosokoneza zochepa zakumbuyo.
Mitundu Yakuletsa Phokoso Logwira Ntchito
Wothandizira ANC: Maikolofoni amayikidwa kunja kwa makapu am'makutu, zomwe zimapangitsa kuti zikhale zogwira mtima motsutsana ndi maphokoso okwera kwambiri monga macheza kapena kutaipa.
Ndemanga za ANC: Maikolofoni mkati mwa makapu am'makutu amayang'anira phokoso lotsalira, kuwongolera kuletsa kumveka kocheperako ngati kumveka kwa injini.
Zophatikiza ANC: Kuphatikiza kwa feedforward ndi mayankho a ANC pakuchita bwino pama frequency onse.
Ubwino & Zochepa
Zabwino:
Zoyenera kuyenda (ndege, masitima apamtunda) ndi malo aphokoso.
Amachepetsa kutopa kwa kumvetsera pochepetsa phokoso lokhazikika.
Zoyipa:
Zosagwira ntchito modzidzimutsa, zosamveka bwino ngati kuwomba m'manja kapena kuuwa.
Pamafunika mphamvu ya batri, yomwe ingachepetse nthawi yogwiritsa ntchito.
Pogwiritsa ntchito njira zamakono zopangira ma siginecha ndi mfundo zafizikiki,mahedifoni oletsa phokosoonjezerani kumveka bwino kwa audio komanso chitonthozo. Kaya zogwiritsidwa ntchito mwaukatswiri kapena zosangalatsa, zimakhalabe chida chofunikira chotsekereza zosokoneza ndikuwongolera kuyang'ana.
Zomvera m'makutu za ENC zimagwiritsa ntchito makina apamwamba omvera kuti achepetse phokoso lakumbuyo panthawi yoyimba komanso kusewera. Mosiyana ndi miyambo ya ANC (Active Noise Cancellation) yomwe imayang'ana kwambiri maphokoso otsika pafupipafupi, ENC imayang'ana kwambiri kudzipatula komanso kupondereza phokoso lachilengedwe kuti limveke bwino pamawu olankhulana.
Momwe ENC Technology Imagwirira Ntchito
Multi-Microphone Array: Zomverera m'makutu za ENC zimakhala ndi maikolofoni angapo oyikidwa bwino kuti azitha kujambula mawu a wogwiritsa ntchito komanso phokoso lozungulira.
Kusanthula Phokoso: Chip chopangidwa ndi DSP chimasanthula mbiri yaphokoso mu nthawi yeniyeni, kusiyanitsa pakati pa zolankhula za anthu ndi zomveka zachilengedwe.
Kuchepetsa Phokoso Losankha: Dongosololi limagwiritsa ntchito ma aligorivimu osinthika kuti atseke phokoso lakumbuyo ndikusunga ma frequency a mawu.
Beamforming Technology: Mahedifoni ena apamwamba a ENC amagwiritsa ntchito maikolofoni olunjika kuti ayang'ane pa mawu a wokamba nkhani kwinaku akuchepetsa phokoso lopanda axis.
Kukhathamiritsa kwa Zotulutsa: Zomvera zomwe zakonzedwa zimatulutsa kutulutsa kwamawu momveka bwino posunga mawu omveka bwino komanso kuchepetsa kamvekedwe kamene kamasokoneza.
Kusiyana Kwakukulu kuchokera ku ANC
Kugwiritsa Ntchito Cholinga: ENC imagwira ntchito bwino pakuyankhulirana kwamawu (kuyimba, misonkhano), pomwe ANC imachita bwino kwambiri pazomvera nyimbo/zomvera.
Kusamalira Phokoso: ENC imayendetsa bwino maphokoso osinthika monga kuchuluka kwa magalimoto, kutayipa kwa kiyibodi, ndi macheza ambiri omwe ANC imalimbana nawo.
Processing Focus: ENC imayika patsogolo kusunga mawu m'malo moletsa phokoso lathunthu.
Njira Zoyendetsera Ntchito
Digital ENC: Imagwiritsa ntchito ma aligorivimu apulogalamu poletsa phokoso (lofala m'makutu a Bluetooth).
Chithunzi cha ENC: Imalemba ntchito zosefera pamlingo wa Hardware (opezeka m'makutu am'mutu amawaya).
Zochita
Ubwino wa Maikolofoni: Ma mics okhudzidwa kwambiri amapangitsa kuti phokoso likhale lolondola.
Processing Power: Tchipisi chothamanga cha DSP chimathandizira kuchepetsa phokoso la latency.
Algorithm Sophistication: Makina ophunzirira makina amasinthasintha bwino ndi malo aphokoso.
Mapulogalamu
Kuyankhulana ndi bizinesi (mayimbidwe amsonkhano)
Kulumikizana pakati ntchito
Mahedifoni amasewera okhala ndi macheza amawu
Zochita zam'munda m'malo aphokoso
Ukadaulo wa ENC umayimira njira yapadera yowongolera phokoso, kukhathamiritsa mahedifoni kuti azitha kufalitsa mawu momveka bwino m'malo mochotsa phokoso lonse. Pamene ntchito yakutali ndi kulumikizana kwa digito kukukulirakulira, ENC ikupitiliza kusinthika ndikusintha koyendetsedwa ndi AI kuti pakhale kudzipatula kwa mawu m'malo aphokoso.
