Imvelaphi yeBluetooth
Itekhnoloji yeBluetooth yenziwa yinkampani yakwa-Ericsson ngo-1994, kwiminyaka embalwa kamva, i-Ericsson yanikela ngayo yaze yaqhutywa ukwenza umfela-ndawonye woshishino lweBluetooth, iBluetooth Special Interest Group (SIG). Iinzame zeBluetooth SIG kunye namalungu ayo akhawulezise kakhulu ukuphuhliswa kobuchwepheshe beBluetooth.
Njengokucaciswa kweBluetooth yokuqala, iBluetooth 1.0 yakhutshwa ngo-1999, kwixesha langaphambili lalo nyaka, kwaphehlelelwa isixhobo sokuqala somthengi weBluetooth, yayiyi-headset engenazandla, yaqalisa uhambo lokufunyanwa kwe-audio yeBluetooth kwaye yatyhila nokubaluleka okungenakuthathelwa indawo kweBluetooth. isandi kwiseti yesixhobo seBluetooth. Phendula kwaye wenze iifowuni, i-fax kunye nokuhanjiswa kwefayile zezinye zeempawu ezinokunikezwa yiBluetooth 1.0, kodwa ukudlala komculo ngeBluetooth kwakungeyona inketho ngoko, esinye sezizathu eziphambili kukuba iiprofayili azilungile.
Yintoni i-HSP/HFP/A2DP
Ukulandela uphuhliso lweenkcazo eziphambili zeBluetooth, i-SIG yeBluetooth ikhuphe iiprofayili ezibaluleke kakhulu ezinxulumene ne-audio:
- Iprofayile yeseti yentloko (HSP) , Ukubonelela ngenkxaso yomsindo weendlela ezimbini kwi-Synhronous Connection Oriented link (SCO), izicelo ezifana nokwenza iifowuni kunye neengqungquthela zokudlala zibonakaliswe kakuhle. Yaqala ukukhutshwa ngo-2001.
- Inkangeleko Engaphathwanga Ngezandla (HFP) , Ukubonelela ngenkxaso yomsindo weendlela ezimbini kwi-Synhronous Connection Oriented link (SCO), izicelo ezifana ne-audio yemoto ibonakaliswe kakuhle. Yaqala ukukhutshwa ngo-2003.
- Iprofayile yoSabelo lweAudiyo ekwinqanaba eliphezulu (A2DP) , ukubonelela ngenkxaso yendlela enye yomsindo ophezulu we-audio kwi-Extended Synchronous Connection Oriented link (eSCO), ukuthwala idatha ye-audio kunye ne-bandwidth elinganiselwe, i-codec ye-SBC inikwe igunya kwiprofayili ye-A2DP, izicelo ezifana nokudlalwa komculo okungenazintambo kubonakaliswe kakuhle. Yaqala ukukhutshwa ngo-2003.
ixesha leBluetooth Audio
Kanye njengokucaciswa kweBluetooth, ukusombulula iingxaki kunye nokuphucula amava, iiprofayili zomsindo weBluetooth zikwanalo nohlaziyo lwenguqulelo ukusukela oko yazalwa, Ukwenziwa kwezixhobo zombane ezingenakubalwa zeBluetooth ezisebenzisa iiprofayili zeaudio zibalisa ibali eliyintsomi le-Bluetooth yomsindo, oku kulandelayo. ixesha leziganeko ezibalulekileyo zemarike malunga nomsindo weBluetooth:
- 2002: I-Audi iveze i-A8 yayo entsha kraca eyayiyimodeli yokuqala yesithuthi enokubonelela nge-Bluetooth audio in-car experience.
- 2004: I-Sony DR-BT20NX ibethe iishelufu, yayiyi-headphone yokuqala yeBluetooth ekwazi ukudlala umculo. Kwangaloo nyaka, iToyota Prius yatya kwimarike kwaye yaba yimodeli yokuqala yemoto ebonelela ngamava okudlala umculo weBluetooth.
- 2016: I-Apple yaphehlelela ii-AirPods zeBluetooth True Wireless Stereo (TWS) ii-earbuds, izise eyona Bluetooth TWS amava kubasebenzisi kwaye yaxhobisa kakhulu imakethi yeBluetooth TWS.
I-Bluetooth SIG ibhengeze uhlaziyo olunxulumene nomsindo kwaye yazisa i-LE audio kwihlabathi kwi-CES 2020. I-LC3 codec, i-multi-stream, i-Auracast yosasazo lomsindo kunye nenkxaso yokuncedisa ukuva yimpawu ezibulalayo ezinikezelwa yi-LE audio, ngoku ihlabathi leBluetooth ukuphuhlisa zombini iaudio yakudala kunye neaudio ye-LE, kwiminyaka ezayo, kufanelekile ukujonga phambili ngakumbi nangakumbi iBluetooth audio audios.
