Kugadzira & Kugadzira PCB yeZvigadzirwa zveOdhiyo zveUnyanzvi zveUSB Audio Interface

Kombuta inogona kuona USB audio interface asi ikaramba ichikundikana muedzo unokosha kumushandisi wayo: kurekodha kwakachena uye kutamba kwakavimbika. Maikorofoni ine ruzha, chiteshi chekutarisa chakadzoserwa kumashure kana chinobatanidza chepamberi chisina kugara zvakanaka chingasaonekwe panguva yekutarisa kubatana kweUSB. Izvi ndizvo zvimwe zvinoita kuti kugadzirwa kwePCB yeUSB audio interface kuve kwakasiyana nekungozadza bhodhi rekudzora redhijitari. Pakuungana kwebhodhi rekusanganisa-console nekaraoke , magain stages emamaikorofoni, mamixing controls uye maaudio outputs zvinofanirwa kutariswa pamwe chete kuti zvionekwe kuti zviri pasi here, kuti zvisanganiswe sei uye kuti zvionekwe kuti zviri papi.

Highleap Electronics inogadzira maPCB asina chinhu uye inogadzira maPCBA emagetsi akagadzirwa nevatengi mumaindasitiri akasiyana-siyana. Ma USB audio interfaces ndeimwe yemapurogiramu atinogona kuongorora ekugadzira nekubatanidza. Hatitengesi interface yakajairwa yeaudio kuburikidza nepeji rino. Chinangwa ndechekubatsira OEM kana timu yekutenga hardware kunzwisisa zvinofanirwa kutsanangurwa, kuchengetedzwa uye kuyedzwa kana circuit yayo yeaudio yatanga kugadzirwa.

Kana USB Audio Interface PCB Ikawana Kana Kurasikirwa Nemhando Yeruzha

Nzira yechiratidzo inoenderana nechigadzirwa. Chishandiso chekurekodha chinogona kutora maikorofoni kana chiratidzo chezviridzwa kuburikidza neanalog front end uye ADC usati watumira odhiyo yedhijitari kuburikidza neUSB. Chishandiso chekuridza chinogona kutora odhiyo yeUSB kuburikidza neDAC uye chobva chatyaira line output kana headphone amplifier. Chishandiso chestudio chine ma input maviri chinogona kuva nenzira dzese dziri mbiri, pamwe chete nekutarisa. Misiyano iyi inosarudza kuti ndeapi zvikamu uye kuongororwa kwekugadzirwa kwakakosha.

Chengeta danho rekuisa zvinhu richienderana

Maikorofoni nezvishandiso zvinopinda mumidziyo zvine simba guru zvinonzwa maunganidziro edunhu rakagamuchirwa. Maamplifier, mareferensi, magain-setting resistors, macoupling parts nemafilters zvinofanirwa kutevedzera BOM yakaburitswa. Kana dhizaini yacho ichipa simba rephantom, switching yayo, dziviriro uye voltage-rated zvikamu zvinoda macheki azvo akatsanangurwa. Chikamu chine package imwechete uye nominal value hachisi chinhu chinongoerekana chagamuchirwa kana paine ruzha.

Usagadzirise nzira yekudzosa zvinhu panguva yekugadzira

Mawachi edhijitari, masaini eUSB, maconverter uye macircuitry eanalog zvinogona kushandiswa pabhodhi diki. Nzira chaiyo yekudzika pasi uye yekugovera magetsi ndeyekugadzirwa kwemagetsi kweOEM; hapana mutemo wepasi rose wekuti PCB yega yega inoda nzvimbo yakakamurwa. Kuchinja kwekugadzira kunokanganisa geometry yemhangura, nzvimbo dzekutarisa, kusefa kana nzvimbo yezvikamu kunofanirwa kuongororwa pane kutorwa senzira dzekugadzirisa maitiro.

Pachigadzirwa chakapedzwa, mibvunzo yakakodzera inonzwika uye inoyerwa: Ko chinhu chimwe nechimwe chinopinzwa chinosvika padanho rakakodzera here? Ko maitiro ekuwana akaenzana here? Zvinobuda zvinosangana nemiganhu yeruzha, mwero uye kukanganiswa kweOEM here? Fekitori inogona kuyedza ichipesana nemiganhu yakatarwa, asi zvirevo zvekushanda kwenzwi zvakaburitswa zvinofanira kubva pane zvinodiwa zvechigadzirwa zvakasimbiswa.

Zvinobatanidza, Zvinodzora uye Chokwadi Chekuungana

Mabhodhi e USB audio interface anowanzo sanganisa ma IC akapfava nema connectors makuru uye ma user controls. XLR kana combo jacks, TRS sockets, encoders uye potentiometers zvinogona kuita kuti mechanical alignment ive yakakosha sekuisa solder. PCBA inogona kupasa bvunzo yemagetsi asi ingave yakaoma kuisa kana connectors dzayo dzisingaenderane nepaneru yepamberi kana yekumashure.

Zvinhu zvitatu zvakakodzera kusimbisa usati wavaka kekutanga

• Kukwana kweConnector uye rutsigiro: tsanangura saizi yegomba rekuisira, dhatamu dzepaneru uye chero kuchengetwa kwemuchina kunodiwa kuti zvikamu zvivhenekerwe nekuiswa kwetambo kakawanda.
• Kubatana neUSB uye simba: tsanangura chinongedzo cheUSB chaicho, kuiswa kwedata uye kurongeka kwemagetsi. Chinhu chekushandisa USB-C chete hazvirevi kuti chigadzirwa chinotsigira USB 3 kana USB Power Delivery.
• Kudzora uye kugadzira mapa enzira: nyora kurongeka kunotarisirwa uye mashandiro ema gain knobs, mabhatani, zvidzori zvemonitor uye zvinobuda kuruboshwe/kurudyi.

Kana imwe nzvimbo ine mabhodhi akasiyana-siyana, kuongorora kwekutanga kunogona kuratidza matambudziko usati waburitsa odha yakakura yekubatanidza. Izvi zvinonyanya kubatsira kune macompact interfaces ane majeki akabatanidzwa nePCB nesimbi.

Zvinogadzirwa neHighleap zveMagetsi Emagetsi Akagadzirwa Nevatengi

Highleap ifekitari yekugadzira nekugadzira maPCB, kwete mugadziri anongogumira pazvigadzirwa zve USB audio. Mabasa edu ekugadzira maelektroni akawanda anopa maelektroni evatengi mumapurogiramu akasiyana. Chirongwa cheodhiyo chinotorwa zvichienderana nekuvakwa kwebhodhi, zvikamu, maitiro ekugadzira uye zvinhu zvinokumbirwa.

Odha isina PCB ine chekuita nedata rekugadzira, zvinhu, kuunganidzwa kwezvikamu, kuboorwa uye zvinodiwa zvekunze. Odha yebhodhi rine vanhu inowedzera kurongeka kwekugovera zvikamu uye basa rekubatanidza bhodhi redunhu . Zvigadzirwa zvakawanda zveaudio zvinosanganisa ma semiconductors epamusoro uye ma passives nezvinobatanidza zvine maburi kana michina, saka maitiro ese ari maviri angangoda kutsanangurwa. Kuronga, kugadzirisa, kuongorora kwakasarudzika uye bvunzo yekushanda zvinotsanangurwa zvakasiyana zvichienderana neprojekiti.

Ndedzipi shanduko dzinoda mvumo?

Sarudzo dzakakosha pakugadzira dzinowanzova idzo timu yekutenga kana yekugadzirisa yaizoona sedzisina basa. Kuchinja op-amp, converter reference, oscillator, USB controller kana connector kunogona kukanganisa mashandiro eruzha, firmware compatibility kana enclosure fit. Ongororo ye design-for-assembly (DFA) inogona kuona nzvimbo, connector uye zvinetso zveprocess, nepo shanduko pakugadzira magetsi kwemutengi dzichiri kuda mvumo.

Saizvozvowo, basa repamusoro pebhodhi harifanirwe kuvhiringidzwa nechigadzirwa chakakwana cheaudio. Maitiro eHost-driver, enclosure grounding, final EMC compliance uye mashandiro ekupedzisira eaudio ekugadzirwa kweproduct zvinoda kusimbiswa kwakakodzera kwesystem-level. Chero basa ripi zvaro rinopfuura kugadzirwa kwePCB uye kuunganidza rinofanira kunge rakajeka muquotation pane kutaurwa neshoko rekuti "turnkey."

Kuedza Nzira Dzechokwadi Dzekuteerera Usati Waburitsa Ruzivo

Kuverenga USB inzira yekutanga inobatsira, asi hairatidzi kuti zvese zvinopinda analog, monitor control kana output zvinoshanda. Pakusarudza nzira dzekuongorora dzePCB nePCBA , maitiro ekugadzira anotsanangurwa neOEM anofanira kuratidza machaneli uye maficha akanyatsoiswa pabhodhi.

Semuenzaniso, chirongwa chekuyedza chakatenderwa nemutengi chingada:

• Kuzivikanwa kwemudziyo uye firmware kana kusimbiswa kwekugadzirisa pane setup yakatsanangurwa yehost.
• Chiratidzo chezwi chinozivikanwa chinoshandiswa kune yega yega input yakatarwa, nechiteshi chinobuda uye level zvichitariswa.
• Kutarisa kubuda kwemutsetse wekuruboshwe/kurudyi kana mahedhifoni uchishandisa mitoro yakatarwa uye mazinga echiratidzo.
• Kushanda kwemabasa e "gain", "mute", "monitor", "buttons", "encoders" kana "phantom-power", kana zviripo.
• Kuyerwa kwakadai sekupindura kwema frequency, ruzha kana THD+N chete kana OEM ichipa miganhu, zvinodiwa nemidziyo uye nzira inodzokororwa.

Chigadzirwa chine nzira dzakawanda chinoda mepu yechiteshi yakajeka; stereo loopback iri nyore haitsigire nzira dzisina hukama. Ma converters akagadziriswazve, majack kana zvikamu zveanalog zvinogonawo kuda kuyedzwazve kwakanangwa. Miganhu yakajeka inoita kuti mhedzisiro ibatsire pakugamuchirwa uye kudzokorora maodha pachinzvimbo chekusiya "audio yakaedzwa" sevimbiso isina kutsanangurwa.

Zvekuisa muRFQ

Kuti uenzanise zvirevo zvePCB nePCBA zvakaenzana, ipa mafaira eGerber kana ODB++, stack-up, assembly drawings, pick-and-place data uye BOM inotenderwa. Kuti uve neaudio build, sanganisirawo connector-to-enclosure dimensions, firmware kana configuration files pazvinenge zvichibvira, input/output channel mepu, nzira yekuyedza yakakumbirwa uye huwandu nebhodhi variant. Sarudza chero zvikamu zvisingafanirwe kutsiviwa. Zvinodiwa zvePCB assembly file zveHighleap zvinopa referensi inobatsira yekuronga core production package.

Highleap Electronics inogona kuongorora magwaro iwayo kuti ione nzvimbo yakajeka yekugadzira PCB yako ye USB audio interface—kana imwe bhodhi remagetsi rakagadzirwa nevatengi. Mutengo unobatsira unoparadzanisa kugadzirwa, kuwanikwa kwezvinhu, kuunganidza, kuronga mapurogiramu uye kuyedza kuitira kuti ugone kuona chaizvo zvirimo usati waisa odha.
