Birasabwa ko amajwi yo hanze yunvikana kumurongo wose yegeranye na MIC bishoboka, bishobora koroshya igishushanyo cya gasketi hamwe nubukanishi bujyanye nayo. Muri icyo gihe, umwobo wijwi ugomba kubikwa kure hashoboka kubavuga hamwe nandi masoko y’urusaku kugirango hagabanuke ingaruka zibi bimenyetso bitari ngombwa kwinjiza MIC.
Niba MIC nyinshi zikoreshwa mugushushanya, guhitamo imyanya ya MIC amajwi yumwanya bigarukira cyane cyane kubicuruzwa byo gusaba no gukoresha algorithm. Guhitamo umwanya wa MIC nu mwobo wijwi hakiri kare mugushushanya birashobora kwirinda ibyangiritse byatewe nimpinduka zanyuma. Igiciro cya PCB ihinduka.
Igishushanyo mbonera
Umurongo wo gusubiza umurongo wa MIC muburyo bwimashini yashushanyije biterwa numurongo wo gusubiza umurongo wa MIC ubwayo hamwe nuburinganire bwa mashini ya buri gice cyumuyoboro winjiza amajwi, harimo ubunini bwijwi ryijwi kumurongo, ubunini bwa gasike nubunini bwa PCB ifungura. Mubyongeyeho, ntihakagombye kubaho kumeneka mumajwi yinjira. Niba haribisohoka, bizatera byoroshye ibibazo by urusaku n urusaku.
Umuyoboro mugufi kandi mugari winjiza nta ngaruka nini kuri MIC yumurongo wo gusubiza umurongo, mugihe umuyoboro muremure kandi muto winjiza urashobora kubyara resonance impanuro yumurongo wamajwi, kandi igishushanyo mbonera cyinjiza gishobora kugera kumajwi aringaniye mumajwi. Kubwibyo, birasabwa ko uwashizeho ibipimisho apima inshuro zisubiza umurongo wa MIC hamwe na chassis hamwe numuyoboro wijwi mugihe cyo gushushanya kugirango harebwe niba imikorere yujuje ibyashizweho.
Kubishushanyo ukoresheje amajwi yimbere MEMS MIC, diameter yo gufungura gaze igomba kuba byibura 0.5mm nini kuruta diameter yumwobo wijwi rya mikoro kugirango wirinde ingaruka zo gutandukana kwifungura rya gaseke na umwanya wo gushyira mubyerekezo x na y, no kwemeza ko gasike ikora nkikimenyetso. Kubikorwa bya MIC, diameter y'imbere ya gaze ntigomba kuba nini cyane, amajwi yose yatemba ashobora gutera echo, urusaku nibibazo byo gusubiza inshuro.
Kubishushanyo ukoresheje amajwi yinyuma (uburebure bwa zeru) MEMS MIC, umuyoboro winjiza amajwi urimo impeta yo gusudira hagati ya MIC na PCB yimashini yose hamwe nu mwobo unyuze kuri PCB yimashini yose. Umwobo wijwi kuri PCB yimashini yose igomba kuba nini muburyo bukwiye kugirango urebe ko itagira ingaruka kumurongo wo gusubiza, ariko kugirango harebwe niba ahantu ho gusudira impeta yubutaka kuri PCB atari nini cyane, birasabwa ko diameter ya PCB ifungura imashini yose iri hagati ya 0.4mm kugeza 0.9mm. Kugirango wirinde kugurisha ibicuruzwa gushonga mu mwobo wijwi no guhagarika umwobo wijwi mugihe cyo kugaruka, umwobo wijwi kuri PCB ntushobora guterwa.
Kugenzura urusaku n'urusaku
Byinshi mubibazo bya echo biterwa no gufunga nabi gasike. Ijwi risohoka kuri gasike rizemerera amajwi yamahembe nandi majwi yinjira imbere murubanza hanyuma bigatorwa na MIC. Bizatera kandi urusaku rwamajwi rwatewe nandi masoko y urusaku gutorwa na MIC. Ibibazo by'ijwi cyangwa urusaku.
Kubibazo bya echo cyangwa urusaku, hariho inzira nyinshi zo kunoza:
A. Kugabanya cyangwa kugabanya ibimenyetso bisohoka amplitude yumuvugizi;
B. Ongera intera iri hagati yumuvugizi na MIC uhindura umwanya wumuvugizi kugeza echo iguye murwego rwemewe;
C. Koresha porogaramu idasanzwe yo gusiba echo kugirango ukureho ibimenyetso byabavuga kumpera ya MIC;
D. Kugabanya inyungu zimbere muri MIC ya chip ya baseband cyangwa chip nyamukuru ukoresheje igenamiterere rya software
Niba ushaka kumenya byinshi, nyamuneka kanda kurubuga rwacu:,
