AudioRoutesInfo 的MAIN_DOCK_SPEAKERS 和 MAIN_SPEAKER的区别
时间: 2023-08-05 18:02:53 浏览: 75
AudioRoutesInfo的MAIN_DOCK_SPEAKERS和MAIN_SPEAKER都是描述设备的音频输出设备。不同之处在于,MAIN_DOCK_SPEAKERS是指连接到设备的主要扬声器,通常是通过底座或连接器连接的扬声器。而MAIN_SPEAKER则是指设备自带的主要扬声器,通常是设备上的内置扬声器。在不使用连接器或底座的情况下,设备的音频输出通常是通过MAIN_SPEAKER来实现的。因此,当设备连接到底座或连接器上时,音频输出会切换到MAIN_DOCK_SPEAKERS。需要注意的是,这些术语可能因设备型号和设置而异。

As an AI language model, I do not have access to information about specific Android software versions or their features. However, generally speaking, A2DP (Advanced Audio Distribution Profile) is a Bluetooth protocol that allows for high-quality stereo audio streaming between devices. A2DP Sink refers to a device that can receive audio from another device, such as a smartphone or tablet, and play it through its speakers or headphones. If Android 11 supports A2DP Sink, it means that devices running this operating system can act as a receiver and play audio from other Bluetooth-enabled devices.
