Urusaku-rusiba na terefoneni tekinoroji yamajwi igezweho igabanya cyane urusaku rudakenewe, rutanga abakoresha uburambe bwo gutega amatwi. Ibyo babigeraho binyuze munzira yitwa Active Noise Control (ANC), ikubiyemo ibikoresho bya elegitoroniki bigezweho bikorana kugirango barwanye amajwi yo hanze.
Uburyo Ikoranabuhanga rya ANC rikora
Kumenya amajwi: Mikoro ntoya yashyizwe muri terefone ifata urusaku rwo hanze mugihe nyacyo.
Isesengura ryibimenyetso: Kumurongo wibikoresho bya digitale (DSP) isesengura inshuro zurusaku na amplitude.
Kurwanya Urusaku: Sisitemu ikora amajwi yinyuma (anti-urusaku) ihwanye na amplitude ariko dogere 180 ziva mubice hamwe n urusaku rwinjira.
Kwivanga kwangiza: Iyo umuyaga urwanya urusaku uhujwe n urusaku rwumwimerere, bahagarika undi binyuze mukwivanga kwangiza.
Sukura Ibisohoka: Umukoresha yumva amajwi yagenewe gusa (nkumuziki cyangwaguhamagara ijwi) hamwe n’imiterere ntoya.
Ubwoko bwo guhagarika urusaku rukomeye
Kugaburira ANC: Mikoro ishyirwa hanze yibikombe byamatwi, bigatuma ikora neza irwanya urusaku rwinshi nko kuganira cyangwa kwandika.
Ibisubizo ANC: Mikoro imbere yibikombe byamatwi ikurikirana urusaku rusigaye, kunoza iseswa ryamajwi make yumvikana nka moteri ivuza.
Hybrid ANC: Ihuriro ryibiryo hamwe nibitekerezo ANC kugirango ikore neza mumirongo yose.
Ibyiza & Imipaka
Ibyiza:
Icyiza cyurugendo (indege, gariyamoshi) hamwe nakazi keza urusaku.
Kugabanya umunaniro wo gutegera ugabanya urusaku ruhoraho.
Ibibi:
Ntibishobora kurwanya amajwi atunguranye, adasanzwe nko gukoma amashyi cyangwa gutontoma.
Irasaba ingufu za bateri, zishobora kugabanya igihe cyo gukoresha.
Mugukoresha ibimenyetso bigezweho gutunganya amahame ya fiziki,urusaku-rusiba na terefoneongera amajwi yumvikana neza. Haba kubikoresha umwuga cyangwa imyidagaduro, bikomeza kuba igikoresho cyingenzi cyo guhagarika ibirangaza no kunoza intumbero.
Headet ya ENC ikoresha gutunganya amajwi yambere kugirango igabanye urusaku rwambere mugihe cyo guhamagara no gukina amajwi. Bitandukanye na ANC gakondo (Active Noise Cancellation) yibanda cyane cyane kumajwi ahoraho amajwi make, ENC yibanda mukwitandukanya no guhagarika urusaku rwibidukikije kugirango urusheho kumvikanisha amajwi muburyo bwitumanaho.
Uburyo Ikoranabuhanga rya ENC rikora
Multi-Microphone Array: Headet ya ENC ikubiyemo mikoro myinshi yashyizwe mubikorwa kugirango ifate ijwi ryumukoresha n urusaku rukikije.
Isesengura ry'urusaku: Chip yubatswe muri DSP isesengura imiterere yurusaku mugihe nyacyo, itandukanya imvugo yabantu nijwi ryibidukikije.
Kugabanya Urusaku Guhitamo: Sisitemu ikoresha algorithms yo guhuza n'imiterere kugirango ihagarike urusaku rwimbere mugihe urinze amajwi.
Ikoranabuhanga.
Gusohora Ibisohoka: Amajwi yatunganijwe atanga amajwi asobanutse mugukomeza imvugo yumvikana no kugabanya amajwi arangaza ibidukikije.
Itandukaniro ryingenzi na ANC
Gusaba Intego: ENC kabuhariwe mu itumanaho ryamajwi (guhamagara, amanama), mugihe ANC irusha abandi umuziki / kumva ibidukikije.
Gukemura urusaku: ENC ikemura neza urusaku ruhinduka nkumuhanda, kwandika clavier, hamwe no kuganira kwabantu ANC irwana nayo.
Kwibanda: ENC ishyira imbere kubika imvugo aho guhagarika urusaku rwuzuye.
Uburyo bwo Gushyira mu bikorwa
Digital ENC: Koresha algorithm ya software kugirango uhagarike urusaku (rusanzwe muri Headet ya Bluetooth).
Analog ENC: Koresha ibyuma-urwego rwo kuyungurura (iboneka mumashanyarazi yumwuga).
Ibikorwa
Ubwiza bwa Microphone: Mics-sensitivite mike itezimbere urusaku rwukuri.
Imbaraga zo gutunganya: Imashini yihuta ya DSP ituma urusaku rwo hasi rwihuta.
Algorithm Kwitonda: Imashini yiga imashini ishingiye kuri sisitemu ihuza urusaku rwibidukikije.
Porogaramu
Itumanaho mu bucuruzi (guhamagara inama)
Menyesha ibikorwa byikigo
Gukina gutegera hamwe no kuganira amajwi
Ibikorwa byo mumirima ahantu huzuye urusaku
Ikoranabuhanga rya ENC ryerekana uburyo bwihariye bwo gucunga urusaku, gutezimbere na terefone kugirango ijwi ryumvikane neza aho kurandura burundu urusaku. Mugihe akazi ka kure hamwe n’itumanaho rya digitale bigenda byiyongera, ENC ikomeje kugenda itera imbere hamwe na AI iterwa no kunoza amajwi meza mu bihe bigenda bisakuza.
