蓝牙联盟（Bluetooth SIG）稍早公开最新技术“Auracast”，将允许蓝牙设备快速分享音乐，或是用于公共空间广播，包含Google Pixel与小米（Xiaomi）都已经确定，会在未来手机支援这项功能。
“Auracast”为Bluetooth LE Audio技术的一部分，主要能将音讯同时传送至多款设备之中，例如用手机、电脑播放音乐，同时把音讯传给周围的多款耳机，即便没有喇叭，也能一起共享相同内容。
更多应用瞄准公共空间，例如在机场、体育馆与餐厅，很多时候开放的电视荧幕都设定为静音，或因为环境太大声听不到，未来透过“Auracast”，民众就可使用自己的耳机，同步收听相关的内容；或在车站、电影院不必拿下耳机，就能听到必要的广播内容，例如地铁进站资讯，也能作为协助听障人士的辅助工具。
此外，使用者可选择要加入的广被内容，或是直接以QR 码、NFC来广播连接。“Auracast”技术必须设备拥有蓝牙5.2以上规格，预计最快年底陆续登场。
