Introduction of True Wireless (TWS) Bluetooth Headset Antenna
Nyob rau hauv xyoo tas los no, qhov tseeb wireless (TWS) Bluetooth headset lag luam tau kub heev, thiab ntau lub xov tooj ntawm tes tau tsim lawv tus kheej TWS headset khoom; nws txaus los qhia qhov tseem ceeb txuas nrog rau lub khw no. Nyob rau hauv tsab xov xwm kawg, peb tau qhia tus pin charging ntawm lub charging compartment ntawm lub wireless wireless (TWS) headset. Niaj hnub no, peb yuav qhia luv luv txog qhov kav hlau txais xov. Peb yuav tham txog qhov tseem ceeb ntawm tus kav hlau txais xov hauv TWS lub mloog pob ntseg, kev taw qhia ntawm Bluetooth kav hlau txais xov ntawm TWS headset, thiab yuav ua li cas xaiv peb thaum tsim TWS headset. Hauv ib qho, qhia lub luag haujlwm, hom, thiab kev xaiv tsim ntawm TWS headset Bluetooth kav hlau txais xov.
Qhov tseem ceeb ntawm TWS Headphone Antennas
Los ntawm cov xov tooj cua qub mus rau cov neeg hais lus ntse tam sim no, los ntawm "cov kwv tij loj" mus rau cov xov tooj ntawm tes, los ntawm ib txwm Bluetooth headsets mus rau TWS wireless headsets. Hauv kev tsim cov khoom siv hluav taws xob siv hluav taws xob, kav hlau txais xov yog ib qho tseem ceeb firmware. Nrog rau kev yug los ntawm lub tswv yim ntawm Is Taws Nem ntawm Txhua Yam, lub luag haujlwm ntawm tus kav hlau txais xov tseem ceeb dua rau cov tsev ntse, tsheb ntse, thiab cov khoom siv ntse coj los txuas thiab tswj los ntawm ib lub tshuab.
TWS earphones is True Wireless Stereo earphones. Txoj kev siv tseem ceeb yog txuas nrog cov khoom siv mobile xws li xov tooj ntawm tes thiab khoos phis tawj los ntawm Bluetooth xov tooj cua zaus thiab tom qab ntawd xa cov ntaub ntawv suab mus rau lub pob ntseg, thiab tom qab ntawd txiav txim siab thiab tso tawm rau ntawm lub pob ntseg kawg. Hauv cov txheej txheem no, tus kav hlau txais xov Bluetooth yuav tsum ua raws li "ntauwd" los sib txuas lus ntawm ob tog thiab ua cov haujlwm xa thiab txais. Yog li ntawd, hauv TWS lub mloog pob ntseg, Bluetooth nti thiab lub kav hlau txais xov Bluetooth sib txuas ua ke, kom paub txog kev xa suab paj nruag wirelessly thiab zam lub shackles ntawm cov xov hlau.
TWS headset Bluetooth antenna introduction
Raws li ib qho tseem ceeb firmware ntawm TWS headset, tam sim no txoj kev loj hlob ntawm Bluetooth kav hlau txais xov yog tus paub tab. Muaj plaub hom PCB on-board kav hlau txais xov, FPC, ceramic, thiab LDS. Xav txog qhov tsos ntawm TWS earphone khoom, zaus band yuav tsum, thiab tus nqi xaiv hom kav hlau txais xov haum tshaj plaws.
1. PCB on-board kav hlau txais xov
Raws li lub npe qhia, PCB onboard kav hlau txais xov yog ib hom kav hlau txais xov uas tau kos ncaj qha rau ntawm lub rooj tsav xwm PCB. Nws yog dav siv nyob rau hauv ib leeg-zaus modules Circuit Court boards xws li Bluetooth modules, WIFI modules, thiab ZIGBEE modules. Hauv TWS earphones, vim qhov txwv ntawm ntim, daim ntawv thov ntawm onboard Bluetooth kav hlau txais xov yog qhov tsawg.
PCB onboard kav hlau txais xov tuaj yeem tsim thiab siv los ntawm cov chaw muag khoom ntawm PCB boards, uas yog sib npaug rau lub voj voog ntawm lub rooj tsavxwm.
Qhov zoo: PCB onboard kav hlau txais xov tsis xav tau ntau yam kev debugging, thiab tuaj yeem kos ncaj qha rau ntawm PCB yam tsis muaj nqi.
Qhov tsis zoo: Cov cheeb tsam xav tau yog qhov loj, qhov kev taw qhia yog ib leeg xwb, tsuas yog haum rau ib leeg zaus, qhov sib xws ntawm cov khoom sib txawv ntawm cov kav hlau txais xov yog qhov tsis zoo, thiab muaj peev xwm tiv thaiv kev cuam tshuam tsis zoo.
2. FPC kav hlau txais xov
FPC kav hlau txais xov hloov zuj zus los ntawm PCB onboard kav hlau txais xov. Vim lub ntim txwv ntawm TWS headset, qhov chaw ntawm lub motherboard sab hauv tsis tuaj yeem ua rau lub kav hlau txais xov. FPC kav hlau txais xov yog sib npaug rau kev coj tus kav hlau txais xov hluav taws xob tawm ntawm PCB thiab siv lwm cov hlau sab nraud los ua tus kav hlau txais xov sib cais. Yog li ntawd nws tuaj yeem muab tso rau hauv qhov chaw sab hauv ntawm TWS headset.
FPC kav hlau txais xov tuaj yeem pom tau los ntawm PCB pawg thawj coj saib ntawm lub rooj tsavxwm mos thiab cov khoom siv tau yooj yim.
Qhov zoo: Muaj feem xyuam rau cov khoom siv hluav taws xob me me feem ntau, cov zaus bands tuaj yeem ua tau kuj nplua nuj, kev ua tau zoo dua, thiab tus nqi qis dua.
Disadvantages: Txhua yam khoom yuav tsum tau ua tus kheej debugged thiab manually patched.
3. LDS kav hlau txais xov
LDS kav hlau txais xov yog ib qho kev txhim kho ntxiv ntawm FPC kav hlau txais xov. Txawm hais tias FPC kav hlau txais xov tau tuaj yeem siv qhov chaw sab hauv ntawm lub mloog pob ntseg mus rau qhov zoo, nws tseem xav tau lub dav hlau tiaj tus los txuas rau nws.
LDS kav hlau txais xov siv laser ncaj qha molding tshuab, uas siv laser tshuab ncaj qha rau cov hlau kav hlau txais xov cov qauv ntawm cov brackets, npog daim hlau, thiab lwm yam, uas tuaj yeem lasered rau qhov chaw tsis sib xws hauv lub pob ntseg, ntxiv rau qhov chaw sab hauv ntawm lub pob ntseg.
Cov neeg tsim khoom ntawm LDS kav hlau txais xov rau kev ua laser, tshuab laser, thiab tshuab electroplating tuaj yeem txhawb nqa nws.
Qhov zoo: Txhua cov lus qhia tuaj yeem txhawb nqa thiab muaj kev lees paub zoo.
Qhov tsis zoo: Tus nqi kim dua, thiab muaj cov kev cai tshwj xeeb rau cov khoom siv ntawm cov khoom siv sab nrauv.
4. Ceramic kav hlau txais xov
Cov kav hlau txais xov ceramic yog lwm cov khoom siv kav hlau txais xov uas tau siv dav hauv Bluetooth module li. Nws yog lub npe hu ua tom qab siv cov plhaub ceramic. Nws yog tsuas yog muab faib ua ob hom: thaiv ceramic kav hlau txais xov thiab ntau txheej ceramic kav hlau txais xov.
Lub thaiv cov kav hlau txais xov ceramic yog luam tawm cov hlau ntawm lub kav hlau txais xov ntawm cov kav hlau txais xov ceev ceev, thiab cov kav hlau txais xov ntau txheej tuaj yeem luam tawm ntawm txhua txheej ceramic dielectric raws li cov qauv tsim, yog li txo qhov loj ntawm lub kav hlau txais xov.
Qhov zoo: me me, daim ntawv thov yooj yim, tus nqi qis, kev ua haujlwm zoo, thiab tsuas yog siv qhov chaw me me xwb.
Disadvantages: Cov kev xav tau ntawm thaj chaw tshem tawm yog qhov siab, qhov kev taw qhia yog ib leeg, thiab muaj cov kev xav tau rau qhov chaw tso kawm.
Peb tau kawm los ntawm kev rhuav tshem ntawm TWS earphones yav dhau los uas vim muaj qhov txwv ntim, PCB onboard antennas kuj tsis tshua siv hauv TWS earphones. Xaiv raws li cov kev xav tau ntawm koj cov khoom, tsis muaj ib hom kev siv tas li.
Yuav xaiv lub kav hlau txais xov zoo li cas
Kev hais lus theoretical, hais txog tus nqi, PCB thiab FPC kav hlau txais xov raug nqi tsawg, cov kav hlau txais xov ceramic yog nruab nrab, thiab LDS kav hlau txais xov yog kim dua; thiab hais txog qhov chaw siv, LDS kav hlau txais xov yog qhov hloov tau yooj yim tshaj plaws thiab tuaj yeem siv tag nrho ntawm qhov chaw sab hauv ntawm lub mloog pob ntseg.
Hais txog kev ua tau zoo, kev xa thiab txais lub peev xwm ntawm cov kav hlau txais xov sab nraud feem ntau zoo dua li cov kav hlau txais xov built-in. TWS headsets yog tsim los nrog cov kav hlau txais xov built-in vim muaj qhov txwv ntim thiab qhov yuav tsum tau txav mus los. Qhov kev ua tau zoo kuj zoo ib yam, thiab nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog ntau yam los xaiv lub kav hlau txais xov tsim nyog.
Tus tsim ntawm lub kav hlau txais xov Bluetooth ntawm TWS lub mloog pob ntseg cuam tshuam rau kev sib txuas lus zoo ntawm Bluetooth kev sib txuas lus, uas cuam tshuam rau cov neeg siv kev paub tiag tiag. Kev xaiv ntawm Bluetooth kav hlau txais xov cuam tshuam los ntawm ntau yam xws li kev ua haujlwm, zaus band, tus nqi, thiab siv qhov chaw. Tsuas yog los ntawm kev xav txog cov khoom tshwj xeeb thiab kev siv cov xwm txheej, thiab xaiv lub kav hlau txais xov tsim nyog, tuaj yeem ua haujlwm siab tshaj plaws ntawm cov khoom.
