Lub tshuab ua haujlwm bluetooth txuas ntxiv yog hom wireless wireless kis thev naus laus zis. Lub sijhawm ntawd, wireless tshuab tau nyob ntev ntev, thiab qee qhov lawv tau nkag mus rau theem paub tab. Piv txwv li, infrared thev naus laus zis muaj nyob hauv ntau yam khoom siv hluav taws xob xws li khoom siv hauv tsev, khoos phis tawj, xov tooj ntawm tes, thiab PDA. Qhov loj tshaj plaws ntawm infrared tshuab yog nws cov nqi qis. Tab sis nws cov lus luv kuj tseem ua rau neeg tuag taus: qeeb qeeb, luv luv, kev nyab xeeb tsis zoo, tsis muaj zog tiv thaiv kev cuam tshuam, yog li siv tshuab wireless muaj zog ntau dua yuav tsum tau yug los ntawm lub sijhawm kom tau raws li tib neeg txoj kev xav rau kev ywj pheej, xws li bluetooth amplifier technology.

Los ntawm keeb kwm kev txhim kho ntawm bluetooth amplifier

Muaj kev sib tw tsiv nyob rau hauv bluetooth amplifier chip kev ua lag luam, vim hais tias lub nti yog cov tuam txhab tseem ceeb rau kev hloov pauv ntawm cov thev naus laus zis tshiab rau cov khoom lag luam. Seb bluetooth amplifier tshuab khoom lag luam muaj peev xwm nkag mus rau qhov kev lag luam loj nyob ntawm seb cov tshuab chip tsim lub tshuab tuaj yeem khaws cia. Ntsig txog kev lag luam loj hlob, ntau lub ntiaj teb cov khoom lag luam semiconductor tuam txhab tau nqis peev rau hauv kev lag luam bluetooth amplifier chips txhawm rau txhawm rau tswj hwm qhov siab ntawm cov lag luam. Cov lag luam zoo hauv xov tooj txawb Ericsson thiab Nokia tau tsim ob nti nti daws teeb meem uas tau raws li cov qib thev naus laus zis tam sim no. Ericsson thaum ntxov bluetooth amplifier headsets thiab bluetooth amplifier lub xov tooj txawb tau tsim-nyob rau hauv lawv tus kheej bluetooth amplifier chips. Tom qab ntawd, Philips Semiconductors ib zaug nyob hauv cov lus qhia kom ua qhov siab ntawm cov khoom siv chip vim nws txoj kev vam meej ntawm VLS1 Technology hauv xyoo 1999. Motorola, Toshiba, Intel, thiab IBM kuj tau koom nrog kev tsim nti lossis yuav cov khoom sib txuas nrog cov ntawv tso cai, tab sis tsis muaj kev sib tawg Cov.

Nyob rau xyoo 2002, Cambridge Silicon Xov tooj cua (CSR) hauv tebchaws Askiv tau qhia qhov tseeb CMOS ib leeg nti kev daws teeb meem (high-zaus tivthaiv kaum baseband maub los) hu ua BlueCore (bluetooth amplifier core), thiab muaj kev sib xyaw ua tiav nws cov tuaj tshiab version BlueCore 2-Tus nqi ntawm cov sab nraud coj ua poob rau tsawg dua US $ 5. Thaum kawg, bluetooth amplifier cov khoom lag luam tawm. Lub tuam txhab cov khoom ntawm bluetooth amplifier chips nyob rau xyoo 2002 suav txog kwv yees li 18% ntawm tag nrho kev ua lag luam. Ntawm cov khoom siv tam sim no rau cov neeg siv kawg uas ua raws li bluetooth amplifier 1.1 tus qauv, 59% yog nruab nrog cov khoom lag luam CSR. CSR tseem muaj tus neeg sib tw, Texas Seev Lus. Texas Cov Khoom Siv kuj tau tsim tawm ib qho nkaus xwb bluetooth amplifier hauv xyoo 2002, uas yog tswj hwm los ntawm lub koos pij tawj ntawm thaj tsam 25mW, uas yog lub zog txuag hluav taws xob. Cov khoom chip no yog hu ua BRF6100. Tus nqi rau kev yuav khoom loj tsuas yog 3 txog 4 Asmeskas las. Texas Instruments tseem tab tom txhim kho lub nti ua ke ntawm bluetooth amplifier thiab IEEE802.11b. Nws kwv yees tias cov kev qhia ntawm cov khoom no yuav txo tus nqi ntxiv ntawm bluetooth amplifier chips. Kev txhim kho ntawm WUSB thev naus laus zis yuav twv yuav raug ntsib los ntawm qhov nyuaj ib yam, thiab tus nqi yuav dhau los ua teeb meem kev txhim kho rau WUSB.

Bluetooth amplifier txhawb ntau dua thiab ntau dua haujlwm

Bluetooth amplifier chip specifications tau dhau los ntawm peb qib ntawm txoj kev loj hlob: 1.0, 1.1 thiab qhov tseeb version 1.2. Cov ntaub ntawv sib kis thiab audio kis tau yog ob txoj haujlwm tseem ceeb ntawm bluetooth amplifier, suav nrog cov chaw nres nkoj virtual ntawm bluetooth amplifier, cov ntaub ntawv sib kis, xov tooj sib txuas, lub suab qhov rooj, fax, lub mloog pob ntseg, cov ntaub ntawv tus kheej tswj synchronization, bluetooth amplifier network, khoom siv ergonomic, thiab lwm yam Ob txoj haujlwm yooj yim no tau nthuav dav. Nws tsim nyog sau cia tias ntau lub bluetooth amplifier khoom siv tau tsuas yog muab qee qhov ntawm cov haujlwm no. CSR's BlueCore 3bluetooth amplifier chip siv cov ntawv tso tawm tshiab 1.2, thiab nws cov khoom coj ua tau tseem tsis tau tsim ua lag luam loj. BlueCore 3 muaj "kev sib txuas ceev" muaj nuj nqi uas ua rau lub sijhawm luv luv ntawm lub bluetooth amplifier ntaus ntawv mus rau tsawg dua 1 thib ob, thiab tuaj yeem sib zog dhia lub suab thaum sib txuas lus kom tsis txhob cuam tshuam IEEE802.11b cuam.

Tseem muaj cov haujlwm los txhim kho lub suab kis tau zoo thiab txuas ntxiv bluetooth amplifier khoom. Dab tsi txaus siab yog qhov nti kho vajtse raws li version 1.1 tsis tas yuav hloov pauv, tsuas yog kho cov firmware (firmware, zoo ib yam li motherboard BIOS) ntxiv cov haujlwm saum toj no. Ntxiv rau, tag nrho cov kev siv fais fab loj yog 18% qis dua BlueCore 2-Sab Nraud. Raws li cov ntaub ntawv tshaj tawm, WUSB thev naus laus zis muaj cov txuj ci ntau dua li bluetooth amplifier technology, tab sis kev nce qib ntawm cov ntawv thov yog qhov tseeb tuag ntawm WUSB thev naus laus zis.
