style="text-indent:25px">很多用過藍牙耳機的人都有可能有這樣的體會：當你用藍牙耳機聽音樂時，聲音時而斷斷連續(xù)；看電影或者視頻時，畫面和語音時而不同步。這就是音頻信號缺失及延時問題，而這個問題的產(chǎn)生，卻跟藍牙芯片支持的音頻傳輸編碼格式有關(guān)。藍牙應(yīng)用于音頻傳輸，實際上都是基于A2DP協(xié)議。而A2DP簡單來說只是定義了異步無連接信道上傳送單聲道或立體聲等高質(zhì)量音頻信息的協(xié)議和過程。這個協(xié)議類似于音頻數(shù)據(jù)傳輸管道。而通過藍牙傳送的數(shù)據(jù)，根據(jù)其編碼格式不同。藍牙音箱擺脫有線束縛，如今的藍牙協(xié)議已經(jīng)普及到了4.0以上。揚州新型藍牙耳機</p><p style="text-indent:25px">藍牙系列產(chǎn)品技術(shù)的發(fā)展前景：普及藍牙技術(shù)的認知與利用。溫州女士藍牙耳機</p><p style="text-indent:25px">藍牙耳機的另一重要取決點在于傳輸距離，這與藍牙版本無關(guān)，而取決于藍牙技術(shù)PowerClass。大部分手機與移動裝置所使用的是PowerClass2，標準傳輸距離10米；而升級的PowerClass1則是將傳輸距離提升到100米，兩種版本都支持A2DP立體聲傳輸協(xié)議，可與立體聲耳機互聯(lián)。一般而言，手機與藍牙耳機的距離不會太遠，如果中間沒有大的障礙物，在7米之內(nèi)傳輸質(zhì)量都很好，超過8米將出現(xiàn)斷點！超過10米藍牙設(shè)備之間將失去連接。根據(jù)實際使用的感覺，手機與藍牙耳機的距離，和通話噪音成正比；另外，使用立體聲藍牙耳機欣賞音樂時，也不要距離手機太遠，否則容易出現(xiàn)斷續(xù)的現(xiàn)象。有許多消費者隨時把藍牙耳機掛在耳朵上，所以造型則變成了基本條件；而每個人耳朵外形不同，用戶在購買前得要試一試佩戴舒適度，再決定購買；佩戴眼鏡的人更需要注意，許多藍牙耳機的掛耳部分會和眼鏡腿排斥，一定要試帶后才知道。溫州女士藍牙耳機</p><p
