Khoom Description

Tsim los ua lub hauv paus tswj hwm rau cov neeg hais lus ntse niaj hnub no, PCBA rau Smart Speaker, muab siab -kev ua suab nrov thiab kev sib txuas tsis sib haum. Nws koom ua ke lub siab -kev ua tau zoo ntau- cov tub ntxhais processor rau kev ua haujlwm zoo lub suab teeb liab thiab lub suab algorithms, txhawb nqa deb - lub suab khaws nrog beamforming thiab suab nrov tshem tawm. Lub Rooj Tswjhwm Saib muaj ntau-channel audio decoding thiab amplification los tsav ntau yam hais lus, kom ntseeg tau tias cov suab nrov nplua nuj thiab meej. Nws txhawb nqa cov txheej txheem wireless tseem ceeb suav nrog Wi-Fi, Bluetooth, thiab Zigbee, ua kom muaj kev sib txuas ruaj khov rau streaming, ntse tswj hauv tsev, thiab ntau-chav suab synchronization. Ua-hauv kev ruaj ntseg chips muab kho vajtse- qib kev tiv thaiv cov ntaub ntawv, thaum hloov pauv hloov pauv tau tso cai rau kev hloov kho yav tom ntej. Lub compact thiab thermally optimized tsim ua kom ntseeg tau 24/7 kev ua haujlwm hauv ntau qhov chaw.

Ntau lawm thiab Zoo

PCBA rau Smart Speaker tsim cov txheej txheem siv cov txheej txheem kev tswj hwm nruj kom ntseeg tau tias lub suab ua tau zoo thiab kev ntseeg tau. Txhua lub Rooj Tswjhwm Saib Xyuas Kev Xeem, suav nrog Hauv -Circuit Test (ICT), Automated Optical Inspection (AOI), thiab Functional Test (FCT). FCT nruj me ntsis saib xyuas tag nrho cov haujlwm tseem ceeb: lub suab decoding zoo thoob plaws cov codecs sib txawv, wireless txuas kev ruaj ntseg rau Wi-Fi thiab Bluetooth, microphone array rhiab heev, thiab amplifier tso zis kev ua tau zoo.

Peb siv high -precision SMT kab nruab nrog X-ray soj ntsuam rau BGAs thiab advanced SPI rau solder paste xyuas. Dedicated audio test Chambers yog siv los calibrate thiab txheeb xyuas qhov tsis muaj acoustic. RF shielding thiab thermal tswj tau ua tib zoo validated thaum sib dhos.

Peb cov saw hlau zoo tshaj plaws txhawb nqa tus qauv coj lub sijhawm ntawm 5-6 lub lis piam. Nrog siab- sib xyaw, siab- ntim SMT cov peev txheej tsim khoom thiab cov khoom siv ua haujlwm siab, peb muaj lub peev xwm loj tuaj yeem txhawb nqa ntau lawm thaum tswj xyuas qhov zoo ib yam thiab raws sij hawm xa tuaj rau kev txiav txim loj.

Q&A

Q: PCBA rau Smart Speaker, dab tsi yog qhov tshwj xeeb tsim kev txiav txim siab piv rau lwm yam khoom siv suab lossis wireless?

A:Qhov kev sib tw tseem ceeb yog nyob rau hauv kev sib koom ua ke siab -kev ncaj ncees lub suab, kev sib txuas tsis muaj zog, thiab kev nkag siab zoo ntawm lub microphone ntawm ib lub rooj tsav xwm yam tsis muaj kev cuam tshuam. Qhov no xav tau ib txheej txheej txheej txheej zoo- nce thiab qhov chaw tso tawm tswv yim kom cais tawm siab - lub zog amplifiers, siab - ceev RF circuits, thiab qis - suab nrov analog microphone txoj hauv kev. Kev tswj xyuas thermal zoo rau kev ua suab nrov thiab ntau -chav synchronization raws tu qauv kuj tseem yog cov qauv tsim tshwj xeeb uas tsis muaj nyob hauv cov khoom siv yooj yim dua.

Q: Koj yuav ua li cas thiaj li paub tseeb qhov ua tau zoo ntawm acoustic thiab lub suab lees paub kev ntseeg siab hauv kev tsim khoom?

A:Peb ua haujlwm tshwj xeeb anechoic thiab semi{0}}anechoic xeem chambers ua ib feem ntawm peb cov kab ntau lawm. Txhua PCBA tau dhau lub hom phiaj kev sim suab- ntsuas Tag Nrho Harmonic Distortion (THD), Teeb Pom Kev -rau-Noise Ratio (SNR), thiab teb zaus. Rau kev lees paub lub suab, peb ua cov kev sim ua haujlwm siv cov khoom siv suab ntsuas los sim ua kom deb li deb- lub suab lus txib ntawm cov kaum sib txawv thiab cov suab nrov tom qab, ua kom lub microphone array thiab beamforming algorithms ua tau zoo.

Q: Koj ua li cas tswj cov saw hlau thiab cov khoom zoo rau cov khoom siv, cov neeg siv khoom zoo li no - tsom rau cov khoom?

A:Peb tuav lub sijhawm ntev - koom tes nrog cov khoom lag luam tseem ceeb semiconductor rau cov khoom tseem ceeb xws li processors, codecs, thiab connectivity modules. Qhov no muab cov khoom ruaj khov thiab nkag mus rau cov ntaub ntawv txog lub neej thaum ntxov. Rau tag nrho cov khoom BOM, peb tswj xyuas qhov kev lees paub nruj thiab cov txheej txheem traceability. Cov ICs tseem ceeb yog muab los ntawm cov neeg muag khoom franchised, thiab peb ua batch- qib sampling xeem, suav nrog X-ray thiab decapsulation rau siab- qhov pheej hmoo, kom txo tau cov kev pheej hmoo cuav uas muaj nyob hauv cov khoom siv hluav taws xob.
