A sink of anything (at least in the information world) is a
destination. So a telephone handset is an audio sink (the earpiece,
anyway - the microphone would be a source).
sink, 是一个目的。因此,电话的耳机,是一个 andio sink(听筒,无论如何,mic会是一个audio 源),

A Bluetooth headset is an audio sink. A hands free kit is an audio sink. .
蓝牙耳机是一个 audio sink。免提是一个audio sink。

A gateway is a translation, mapping or director (or some mixture of the three) point in a network.
网关是网络中的一个翻译,映射或者定向(重定向)(或者三者混合)的点。

A cell phone with a bluetooth interface (capable of supporting a headset, for instance) is an audio gateway. It takes a GSM signal and formats it suitably for Bluetooth (translation) and provides the connection control to the headset (mapping and redirect).
带有蓝牙接口(例如,支持耳机)的电话,是一个 audio 网关。它拿到GSM信号,并为蓝牙进行适当的格式化(翻译),并为耳机提供链接控制(映射和重定向)。

简单理解, 就是, 谁放(给予), 谁就是 audio source, 谁听(接受), 谁就是 audio sink
