蓝牙耳机频繁断连?可能是这家购物网站偷偷占用了你的设备
昨晚我戴着 AirPods 办公,被一个购物标签页卡死了 我桌上开着 Notion、Slack、AliExpress 三个窗口,AirPods 一边连电脑一边连手机。AliExpress 一开,耳机就卡死。 后来扒出来:AliExpress 网页在后台偷偷跑一种叫"音频指纹"的东西——它让浏览器一直播放一段极小的无声音频来识别你这台设备,顺带把你电脑的蓝牙音频通道也占满了。你挂耳机多点连接(同时连电脑和手机)的时候,它就一直在抢线。 我不是技术背景,搞了好几天才搞明白。中间一度以为是 AirPods 电池老化,准备买新的——结果是浏览器在作怪。这玩意不是 AliExpress 独有,但购物类网站里它做得最狠。我做 TikTok Shop 选品那阵,每天挂它十几个小时,等于整天免费给它白打工。
