原标题：基于Qualcomm QCC5120支持Broadcast Audio的蓝牙耳机方案

　　Qualcomm®QCC5120蓝牙SOC方案现已支持其Broadcast Audio技术。Qualcomm® Broadcast Audio旨在支持从一个蓝牙源向多个耳机或音箱以近乎完美的同步性进行音频流传输。该技术旨在支持利用蓝牙进行“一对多”的声音广播，从而帮助扩展传统蓝牙的功能。Qualcomm Broadcast Audio支持多音箱的即兴聚会，以及从单部智能手机向多个耳机分享、聆听相同音乐，或进行团体音频导览。

　　Qualcomm Broadcast Audio特性包括：

　　更简单的终端设置和配对及终端管理，可帮助用户更轻松地管理哪些终端可以加入

　　在蓝牙覆盖范围内，向多个终端进行广播

　　内置稳健性、自动重新传输和丢包弥补

　　加密音频传输可帮助降低窃听风险
