Tšimoloho ea Bluetooth
Theknoloji ya Bluetooth e thehilwe ke khamphani ya Ericsson ka 1994, dilemo tse mmalwa hamorao, Ericsson e ile ya fana ka yona mme ya etswa ho theha selekane sa indasteri ya Bluetooth, Bluetooth Special Interest Group (SIG). Boiteko ba Bluetooth SIG le litho tsa eona bo potlakisitse haholo nts'etsopele ea theknoloji ea Bluetooth.
E le tlhaloso ea pele ea Bluetooth, Bluetooth 1.0 e ile ea lokolloa ka 1999, nako ea pejana ea selemo seo, ho ile ha qalisoa sesebelisoa sa pele sa Bluetooth, e ne e le semaele se se nang matsoho, se qalile leeto la ho sibolla molumo oa Bluetooth hape se senola bohlokoa bo ke keng ba fetoha ba Bluetooth. audio ho sete ea likarolo tsa Bluetooth. Araba le ho etsa mehala ea mohala, fekse le phetiso ea lifaele ke tse ling tsa likarolo tseo Bluetooth 1.0 e ka fanang ka tsona, empa ho bapala 'mino ka Bluetooth e ne e se khetho ka nako eo, le leng la mabaka a bohlokoa ke hore li-profile ha li so lokisoe.
HSP/HFP/A2DP ke eng
Kamora ho nts'etsapele lintlha tsa mantlha tsa Bluetooth, Bluetooth SIG e boetse e lokolotse lintlha tsa bohlokoa tse amanang le molumo:
- Profaele ea li-headphone (HSP) , ho fana ka tšehetso bakeng sa molumo oa litsela tse peli holim'a Synchronous Connection Oriented link (SCO), likopo tse kang ho letsetsa mohala le lipapali tsa lipapali li hlahisoa hantle. E ile ea lokolloa ka lekhetlo la pele ka 2001.
- Boemo ba Matsoho (HFP) , e fana ka tšehetso bakeng sa molumo oa litsela tse peli holim'a Synchronous Connection Oriented link (SCO), likopo tse kang molumo oa koloing li hlahisoa hantle. E ile ea lokolloa ka lekhetlo la pele ka 2003.
- Profaele e Tsoetseng Pele ea Phano ea Molumo (A2DP) , ho fana ka ts'ehetso bakeng sa molumo oa boleng bo phahameng ba tsela e le 'ngoe holim'a sehokelo sa Extended Synchronous Connection Oriented (eSCO), ho nka lintlha tse ngata tsa molumo ka bandwidth e lekanyelitsoeng, SBC codec e laetsoe ho profil ea A2DP, likopo tse kang ho bapala 'mino o se nang mohala li hlahisoa hantle. E ile ea lokolloa ka lekhetlo la pele ka 2003.
Kemiso ea nako ea Bluetooth Audio
Joalo ka sebopeho sa mantlha sa Bluetooth, ho rarolla mathata le ho ntlafatsa boiphihlelo, li-profiles tsa audio tsa Bluetooth le tsona li bile le lintlafatso tsa mofuta ho tloha ha e tsoaloa, Ho theoa ha lisebelisoa tse ngata tsa elektroniki tsa Bluetooth tse sebelisang li-profile tsa molumo ho pheta pale e tsebahalang ea molumo oa Bluetooth, e latelang ke kemiso ea nako ea liketsahalo tsa bohlokoa tsa 'maraka mabapi le molumo oa Bluetooth:
- 2002: Audi e senotse mofuta oa eona o mocha oa A8 oo e neng e le mofuta oa pele oa koloi o ka fanang ka boiphihlelo ba molumo oa Bluetooth ka koloing.
- 2004: Sony DR-BT20NX e ile ea otla lishelefong, e ne e le mohala oa pele oa Bluetooth o khonang ho bapala 'mino. Selemong sona seo, Toyota Prius e ile ea ja 'marakeng' me ea fetoha mohlala oa pele oa koloi o fanang ka phihlelo ea ho bapala 'mino oa Bluetooth.
- 2016: Apple e phatlalalitse li-earbud tsa AirPods Bluetooth True Wireless Stereo (TWS), e tlisitseng boiphihlelo bo botle ka ho fetesisa ba Bluetooth TWS ho basebelisi mme e lokiselitse 'maraka oa Bluetooth TWS haholo.
Bluetooth SIG e phatlalalitse ntlafatso e amanang le molumo mme e hlahisitse molumo oa LE lefats'eng ka CES 2020. LC3 codec, multi-stream, Auracast broadcast audio le tšehetso ea thuso ea ho utloa ke likarolo tse bolaeang tseo LE audio e fanang ka tsona, hona joale lefatše la Bluetooth le Ho nts'etsapele ka molumo oa khale le molumo oa LE, lilemong tse tlang, ho bohlokoa ho lebella lisebelisoa tsa elektroniki tsa audio tsa Bluetooth.
