bluetooth是通訊技術之名稱，視為專有名詞，不可變更。

"Bluetooth" is a technology regarding the transmission of electronic data and should be treated as a proper noun. "Bluetooth" is simply a bad translation from Chinese.

補充:

藍芽（Bluetooth）一詞是古北歐語 Blåtand / Blåtann 的一個英語化變體，藍牙的標誌是 （Hagall）和 （Bjarkan）的組合，也就是 Harald Blåtand 的首字母 HB 的合寫。

這個詞的來源是10世紀丹麥和挪威國王藍牙哈拉爾（丹麥語：Harald Blåtand Gormsen），借國王的綽號「Blåtand」當名稱，直接翻譯成中文爲「藍牙」（blå＝藍，tand＝牙）。在中文圈，「藍牙」又稱為「藍芽」。2006年，藍牙技術聯盟組織已將全球中文譯名統一改採直譯為「藍牙」，並註冊為該組織的註冊商標。
