Kugadzira PCB yeSoundbar yeHDMI eARC, DSP uye Multichannel Class-D Audio

PCB yesoundbar inogona kusanganisa HDMI/eARC, ma inputs e optical kana analog, audio SoC/DSP, nzira dzakasiyana-siyana dzeDAC kana digital-amplifier, Bluetooth/Wi-Fi uye high-power Class-D output stage mukati menzvimbo refu isina kudzika. Bhodhi rinofanira kuchengetedza ruzha rweaudio rwakaderera uye kubatana kwe wireless/HDMI kwakavimbika uku richiparadzira kupisa kubva kuma amplifier channels akawanda uye kudzora switching EMI pedyo nemaspika, ma antenna nema microphone.

Highleap Electronics inogadzira uye inounganidza maPCB nemaPCBA akagadzirwa nevatengi. Mapurogiramu anogona kusanganisira bhodhi rekudzora redhijitari/HDMI, bhodhi reamplifier, bhodhi remodule risina waya kana PCBA huru yakabatanidzwa, ine masourcing, programming, inspection uye kuyedzwa kweaudio kwakatsanangurwa nevatengi.

1. Kugadzira uye Kugadzira PCB yeKey Soundbar

Magadzirirwo ebhawa renzwi anofanira kutsanangurwa kubva pahuwandu hwemachaneli, topology yemaspika uye mainterface ekupinda. Bhawa re2.0 riri nyore uye chigadzirwa chinonyudza chine 5.1.2 kana chepamusoro chinogona kuda simba rePCB rakasiyana, DSP uye magadzirirwo ekupisa.

• Kupinda kweHDMI/eARC: Bhodhi rinofanira kutsanangura zvinodiwa chaizvo zveHDMI/eARC, chinongedzo uye maitiro efirmware. Chikamu chekumhanya kwakanyanya chinogona kutevera PCB yeHDMI interface zvirambidzo zvekugadzira.
• Kugadziriswa kweDSP uye nzira: Crossovers, EQ, bass management, delay, dynamics uye immersive rendering zvinoenderana neSoC/DSP yakasarudzwa. Chikamu chedhijitari chinogona kuongororwa uchishandisa odhiyo DSP PCB kufunga.
• Kugoverwa kweI²S/TDM: Mabhazi enzwi ane nzira dzakawanda anofanira kuchengetedza wachi dzakachena uye magadzirirwo enzira akajeka pakati peDSP, DACs uye ma amplifiers edhijitari.
• Chikamu chesimba cheKirasi-D: Maamplifier anoshanda zvakanyanya anoderedza kupisa asi anogadzira mipendero inochinja-chinja nekukurumidza. Mafirita anobuda, marobho emagetsi uye zvinobatanidza maspika zvinofanirwa kuchengetedzwa kure nenzvimbo dzinonzwa RF/audio.
• Kupararira kwekupisa: Nzira dzakawanda dze amplifier dziri mukati menzvimbo yakatetepa dzinogona kugadzira nzvimbo dzinopisa. Nzira dzePCB copper, thermal vias uye chassis heating dzinofanira kugadzirwa dzakatenderedza mutoro wepanguva imwe chete.
• Kuiswa kwewireless/antenna: Maantenna eBluetooth/Wi-Fi anofanira kuparadzaniswa nema amplifier inductors, switching power converters uye simbi speaker structures.

Sei TDM ichibatsira mu multichannel soundbar?

TDM inobvumira nzira dzakawanda dzedhijitari dzeaudio kuti dzigovane mitsetse mishoma yedata, zvichideredza huwandu hweSoC pin uye wiring pakati pemabhodhi. Mapu ewachi uye machannel-slot achiri kuda kudzorwa nokungwarira pakati pefirmware nehardware.

Ko PCB yeruzha pachayo inogona kushanda seheatsink here?

Ehe, michina yakawanda yeClass-D yakagadzirirwa kuendesa kupisa muPCB copper kuburikidza nemapadhi akavhurika. Mhedzisiro chaiyo yekupisa inoenderana nenzvimbo yemhangura, huwandu hwema layer, ma via, airflow, enclosure contact uye audio load, saka OEM inofanira kusimbisa nzira yese yekupisa.

2. Kubatanidzwa kweHDMI/eARC, DSP, DAC uye Amplifier Signal-Chain

Ma "soundbars" anogona kugamuchira odhiyo kubva kuHDMI/eARC, optical S/PDIF, USB, Bluetooth/Wi-Fi kana analog inputs. DSP inobva yatumira nzira dzakagadziriswa kuenda kumaDAC kana ma "digital-input amplifiers".

• Chinogamuchira HDMI/eARC: Chengetedza HDMI routing iri pfupi uye ichidzorwa uchishandisa HDMI PCB misimboti yekugadzira; simba rekumirira uye eARC control zvinofanirwa kuenderana netransceiver yakasarudzwa.
• Mawachi eDSP nemabhazi: Hunhu hwewachi yeaudio, kurongeka kwekugadzirisazve uye kurongeka kweI²S/TDM zvinofanirwa kunge zvakafanana muDSP nemidziyo yeamplifier.
• Matanho eAnalog/DAC: Kana maDAC ekunze ashandiswa, tevera dhizaini yePCB yeaudio maitiro ekushandisa mareferensi eruzha rushoma, kudzoka kwepasi uye kusefa analog.
• Ma amplifiers ematanho akawanda: Simba rekubuda, kuvharirwa kwemutoro uye huwandu hwemachaneli zvinofanirwa kusarudza mhangura, zvikamu zvefirita uye chiyero chekubatanidza.
• Chinongedzo chesubwoofer isina waya: Bhawa guru rinogona kutumira chiteshi chine frequency yakaderera kune imwe subwoofer yakasiyana. Mhinduro isina waya yakasarudzwa, latency uye firmware yekuwiriranisa zvinofanirwa kudzorwa sechikamu chegadziriro yechigadzirwa.

Magadzirirwo eTI anoratidza kuti ma "soundbars" emazuva ano anogona kusanganisa DSP processing, DAC stages uye ma "Class-D amplifier channels" akawanda mu "scale" imwe chete inogona kuverengeka; huwandu hwe "channels" dzakaburitswa nemutengi uye software yeaudio ine rezinesi ndiyo inofanira kusarudza dhizaini chaiyo yekugadzira.

3. Kuungana kweSoundbar PCBA, Kuongororwa kwePower-Stage uye Kudzora Zvikamu

Mabhodhi esoundbar anosanganisa zvikamu zvedhijitari zvine simba guru uye zvinobatanidza maspika akawanda. Mahwindo ekugadzira anofanirwa kufukidza mativi ese enzvimbo iyoyo.

• Kugadzirwa kweamplifier yeaudio: Highleap inogona kutsigira gungano rePCB reaudio amplifier ine ma amplifiers epadhi rakavhurika, mafirita ekubudisa uye zvinobatanidza maspika.
• Kuwanikwa kwezvinhu kunodzorwa: HDMI receiver, DSP/SoC, DAC, amplifier ICs, inductors uye wireless modules dzinofanira kutevedzera zvinotenderwa nevatengi chikamu chekutsvaga mitemo.
• AOI: AOI muPCBA inogona kuona mapassive, ma amplifier outputs, ma connectors uye polarity vasati vaisa ma heatsinks kana ma shield.
• X-ray: Ma processor eBGA/LGA nemidziyo yeamplifier inogumira pasi inogona kuongororwa uchishandisa X-ray kuongorora pazvinenge zvakakodzera.
• Kusimbiswa kwesimbi yespika/chinongedzo: Mazita echiteshi, polarity uye kurongeka kwekubatanidza kwemuviri zvinofanirwa kuenderana ne enclosure uye firmware channel map. Ma interfaces ane chekuita nemechanical/electrical anogona kuongororwa uchishandisa PCB yemutauri zvinhu zvekugadzira.

Sei ma inductor anoburitsa zvinhu nema speaker connectors achifanira kubatwa sezvikamu zveBOM zvinodzorwa?

Chiyero chavo chazvino, DCR, maitiro ekuzara kwesimba, saizi uye kukodzera kwemuchina zvinogona kukanganisa kushanda zvakanaka, maitiro ekupisa, EMI uye kubuda kweacoustic. Kutsiva kwakafanana hakusi nguva dzose chikamu chakaenzana nekugadzirwa.

4. Kuedzwa Kunoshanda Kwezviteshi Zvenzwi zveSoundbar uye Kubatana

Kuyedzwa kwebasa reSoundbar kunofanira kusimbisa mepu yakazara yechiteshi uye nzira dzekupinda pasina kuedza kutsiva chirongwa cheOEM chekugadzirisa acoustic.

• HDMI/eARC uye ma inputs edhijitari: Simbisai kuwanikwa kwenzvimbo inofambiswa nevatengi uye kukiya odhiyo.
• Mepu yeDSP/chiteshi: Isa matoni anozivikanwa kana zviratidzo zvekuzivikanwa kwechiteshi uye simbisa nzira chaiyo yekufambisa.
• Zvinobuda muamplifier: Shandisa zvinhu zvakatarwa kana zvigadziriso zvespika kuti uone kubuda kwemagetsi, kudzivirira/kudzivirira uye magetsi asina kujairika.
• Wireless/Bluetooth: Simbisa kubatana kana kutaurirana kana kwabatanidzwa muchigadzirwa chakaburitswa.
• FCT yefekitori: Highleap inogona kuita kushanda kushanda uchishandisa manzwi anotsanangurwa nevatengi, zvinhu zvinotakurwa, firmware uye zvinodiwa zvekupasa/kukundikana.

5. Kuburitswa Kwekugadzirwa uye Data reRFQ reKugadzira Soundbar PCB

Kugadzirwa kwesoundbar kunofanirwa kuchengetedza huwandu hwemachaneli, huwandu hweamplifier, speaker impedance, DSP firmware, wireless module uye enclosure thermal design zvakabatana. Mhuri zhinji dzezvigadzirwa dzine PCB imwe chete ine sarudzo dzakasiyana dzekuisa zvinhu, saka kudzora kwakasiyana kwakakosha.

• Pakeji yePCB: Mafaira edhijitari/HDMI uye eamplifier board, zvinodiwa nemhangura, ma thermal pads uye nzvimbo dzekubatanidza.
• BOM: DSP/SoC, DAC, amplifier, inductors, mamodules asina waya, simba uye dzimwe nzira dzakatenderwa.
• Magadzirirwo echiteshi: 2.0/2.1/3.1/5.1.2 kana mamwe magadzirirwo, zvinhu zvinotakura maspika uye mamepu ezvinobuda.
• Firmware: Mufananidzo weDSP, maparamita eEQ/crossover, magadzirirwo asina waya uye mhando yechigadzirwa.
• FCT: Nzira dzekupinda, matoni ekuyedza nzira, mamiriro ekutakura, kuongororwa kwedziviriro uye miganhu yekupisa/yemagetsi.

Rondedzero yeRFQ yekugadzirwa

• Mafaira ekugadzira PCB uye ekuunganidza
• DSP/DAC/amplifier/BOM isina waya
• Tsanangudzo yeHDMI/eARC uye audio-input
• Mepu yemutauri/mutoro uye mepu yekubatanidza
