AUTOMATIC AUDIO-PATH DETERMINATION FOR A PERIPHERAL SPEAKER

摘要

Disclosed are techniques to automatically determine an audio path for a peripheral speaker. A wireless device uses particular wireless-communication methods or techniques, referred to as an audio path, to wirelessly communicate audio data to a speaker system for playback by a peripheral speaker. The device selects an audio path and attempts to send audio data representing known audio to the speaker system using the selected audio path. If a microphone of the device receives the known audio, then the device determines that the selected audio path is supported by the speaker system and thus can be used to communicate audio data to the peripheral speaker. However, if the microphone does not receive the known audio, then the device repeats the selecting of an audio path and attempting to send audio data to the speaker system using the newly selected audio path.

主权项

1. A method in a wireless device of automatically selecting an audio path for communicating audio data from the wireless device to a speaker system including a peripheral speaker, the method comprising:
transmitting audio data representing known audio using a first audio path to the speaker system; checking whether the known audio is acoustically detected at the wireless device; in response to the known audio being acoustically detected at the wireless device after the audio data are transmitted using the first audio path, using the first audio path as the audio path for sending additional audio data to the speaker system; and in response to the known audio not being acoustically detected at the wireless device after the audio data are transmitted using the first audio path:
transmitting the audio data using a second audio path;checking whether the known audio is acoustically detected at the wireless device; andin response to the known audio being acoustically detected at the wireless device after the audio data are transmitted using the second audio path, using the second audio path as the audio path for sending additional audio data to the speaker system.
