Kev tshaj lij wireless microphone system kev tsim kho tshiab tus qauv kev lag luam: 200 xaiv UHF zaus bands thiab qhov tseeb ntau haiv neeg thev naus laus zis ua rau lub sijhawm tshiab ntawm kev cuam tshuam tiv thaiv
Tsis ntev los no, Enping Ruoca Electronics Co., Ltd. tau tso tawm ib qho kev tshaj lij-qib Lub microphone tsis siv neeg lub kaw lus, uas ib zaug ntxiv rov ua dua qhov kev lag luam txhais ntawm kev ruaj khov ntawm kev xa suab wireless thiab kev ua haujlwm nrog200 zaus UHF xaiv tau, Kev txais tos ntawm True Diversity, thiab Kev sib txuas lus infrared ntse (IR Sync)thiab lwm yam thev naus laus zis tseem ceeb. Kev tso tawm cov khoom no yog ib theem tshiab hauv kev tiv thaiv kev cuam tshuam ntawm Lub microphone tsis siv neeg thev naus laus zis hauv cov chaw muaj hluav taws xob nyuaj, tshwj xeeb tshaj yog haum rau cov xwm txheej xav tau siab xws li kev ua yeeb yam loj, kev tshaj tawm thiab kev tshaj tawm hauv TV, thiab kev tsim yeeb yaj kiab thiab kev tshaj lij hauv TV.
Kev tshawb nrhiav txog thev naus laus zis: Kev hloov pauv ntawm UHF band thiab kev tsim qauv sib txawv tiag tiag
Nyob rau hauv thaj teb ntawm Lub microphone tsis siv neegs, UHF zaus band tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov kws tshaj lij vim nws muaj zog nkag mus thiab tiv thaiv kev cuam tshuam. Lub kaw lus tso tawm lub sijhawm no txhawb nqa 200 zaus UHF xaiv tau, thiab cov neeg siv tuaj yeem sib phim qhov zaus zoo tshaj plaws los ntawm kev luam theej duab lossis tsis siv neeg, zam kev tsis sib haum xeeb ntawm cov khoom siv wireless niaj hnub xws li Wi-nkaus thiab 5G. Ua ke nrog cov thev naus laus zis txais tos ntau haiv neeg (kev ua haujlwm ywj pheej ob lub kav hlau txais xov), lub kaw lus tuaj yeem sib piv lub zog teeb liab hauv lub sijhawm tiag tiag thiab hloov mus rau txoj kev zoo dua, txo qhov kev pheej hmoo ntawm kev cuam tshuam zaus los ntawm ntau txoj kev cuam tshuam thiab teeb liab attenuation.
Kev ua haujlwm ntse thiab RF ruaj khov
Cov khoom no innovately qhia txog lub Kev sib txuas lus infrared (IR Sync) muaj nuj nqi, qhov twg cov neeg siv tsuas yog yuav tsum nias lub pob [IR] ntawm lub receiver los synchronize cov zaus parameters rau lub transmitter nrog ib qho nias, zam kev ua haujlwm tedious ntawm kev hloov kho zaus phau ntawv ib txwm muaj. Lub hauv paus PLL (Theem Xauv Lub Voj Voog) kev tswj hwm zaus ntxiv kom ntseeg tau tias muaj kev ruaj khov ntawm cov teeb liab RF, thaum lub sijhawm "Suab nrov xauv" muaj nuj nqi tuaj yeem txheeb xyuas thiab tiv thaiv lub suab nrov RF tsis meej, ua kom ntseeg tau tias kev sib kis ntawm tib neeg lub suab huv si.
Qhov tseem ceeb ntawm kev lag luam: Teeb tsa tus qauv tshiab rau cov xwm txheej kev ua haujlwm
Qhov kev ntseeg tau ntawm cov microphones wireless ncaj qha txiav txim siab qhov zoo ntawm cov ntsiab lus tso tawm hauv cov chaw loj lossis ntau lub koob yees duab tua. Cov khoom no ua ke kev ywj pheej ntawm zaus siab, kev txais tos ntau yam, thiab kev sib dhos ntse los daws cov teeb meem ntawm kev sib tsoo ntawm cov zaus thiab kev poob teeb liab uas kev lag luam tau ntsib ntev. Cov kws tshaj lij hauv kev lag luam taw qhia tias cov thev naus laus zis no yuav ua kom cov txheej txheem ntawm cov khoom siv wireless hloov cov kev daws teeb meem wired hauv cov haujlwm tshaj lij, tshwj xeeb tshaj yog rau cov ntawv thov tseem ceeb hauv kev tshaj tawm thiab kev ncig xyuas loj.
Nrog rau kev hloov pauv ntawm cov thev naus laus zis wireless kis tau tus mob, kev lag luam microphone hloov pauv ntawm "kev siv ua haujlwm" mus rau "kev ruaj khov kawg"kev sib tw. Qhov kev tso tawm ntawm cov khoom no tsis yog tsuas yog qhia txog kev cog qoob loo ntawm cov chaw tsim khoom hauv RF engineering thiab kev paub ntawm cov neeg siv, tab sis kuj muab cov ntaub ntawv tseem ceeb rau kev hloov pauv ntawm kev lag luam.
