ADI's pazasi ruzha gomba MEMS maikorofoni inogona kutengeswa yakananga kuPCB nereflow soldering. Gomba rinoda kugadzirwa muPCB kuti ripfuure ruzha mupakeji yemakrofoni. Pamusoro pezvo, iyo imba inogara PCB nemakrofoni ine kuvhurwa kwekubvumira maikorofoni kutaurirana nekunze kwezvakatipoteredza
Muchimiro chakafanana, maikorofoni inoratidzirwa kune yekunze nharaunda. Munzvimbo dzakaomarara dzekunze, mvura kana zvimwe zvinwiwa zvinogona kupinda maikorofoni mhango uye kukanganisa maikorofoni kuita uye ruzha rwemhando. Kupinzwa kwemvura kunogona kukanganisa zvachose maikorofoni. Ichi chinyorwa chekushandisa chinotsanangura nzira yekudzivirira maikorofoni kuti isakuvadzwe neizvi, ichiita kuti ive yakakodzera kushandiswa munzvimbo dzakanyorova uye dzine guruva, kusanganisira kunyudzwa kwakazara.
dhizaini tsananguro
Kupa kudzivirira kuri nyore, ingoisa chidimbu cherabha yakapfava kana chimwe chinhu sechisimbiso pamberi pemakrofoni. Kuenzaniswa neacoustic impedance yemakrofoni chiteshi, ichi chisimbiso mudhizaini chinoderedza zvakanyanya acoustic impedance. Kana yakagadzirwa nemazvo, chisimbiso hachikanganise maikorofoni senitivity, inongokanganisa zvishoma mhinduro yefrequency, inogumira kune treble renji. Iyo yepazasi maikorofoni inogara yakaiswa paPCB. Muchigadziro ichi, rutivi rwekunze rwePCB rwakafukidzwa nejira rezvinhu zvisingapindi mvura zvakadai sesilicone rabha. Iyi nhanho yezvinhu zvinochinjika inogona kushandiswa sechikamu chekhibhodi kana nhamba keypad, kana inogona kubatanidzwa mumaindasitiri madhizaini. Sezvinoratidzwa muMufananidzo 1, iyi dhizaini yemidziyo inofanirwa kugadzira mhango pamberi pegomba rekurira muPCB, ichivandudza kuenderana kwemufirimu. Iyo firimu inoshanduka inoita kuchengetedza maikorofoni uye inofanirwa kuve yakatetepa sezvinobvira.
Kuoma kwefirimu kunowedzera nekukora kwecube, saka kusarudza iyo yakatetepa inogoneka zvinhu zvekushandisa kunoderedza mhedzisiro yekupindura frequency. Iyo hombe (inoenderana neikorofoni chiteshi uye gomba muPCB) dhayamita mhango uye iyo yakatetepa inochinjika firimu pamwe chete inoumba yakaderera impedance acoustic loop. Iyi yakaderera impedance (inoenderana neiyo maikorofoni yekuisa impedance) inoderedza kurasikirwa kwechiratidzo. Iyo dhayamita yemhango inofanira kunge iri 2 × kusvika 4 × iyo yechiteshi chenzwi, uye kureba kwegomba kunofanira kuva pakati pe0.5 mm ne1.0 mm.
