METHOD FOR DETERMINING ORIENTATION INFORMATION AND ELECTRONIC DEVICE
This application provides a method for determining orientation information and an electronic device. In the method, a first electronic device may determine, based on a received second sequence, whether a device sending a first sequence associated with the second sequence is a second electronic device. If the device sending the first sequence is the second electronic device, the first electronic device may determine orientation information of the second electronic device based on the first sequence. This helps determine an orientation of the second electronic device or an orientation of the first electronic device based on the orientation information, and prevent a user from manually participating in orientation configuration, thereby reducing operation complexity and improving user experience.

In some embodiments, the speakers may receive one or more channels of multi-channel audio content. In some embodiments, one or more wireless speakers are discovered, a prompt identifying at least one speaker location is provided at an output device, a list of wireless speakers is provided to the output device, wherein the list of wireless speakers corresponds to the discovered one or more wireless speakers, a selection of a wireless speaker from the list of wireless speakers is received; and the selected wireless speaker is associated to the at least one speaker location.
Acoustic Change Detection
A loudspeaker cabinet has a number of pairs of microphones, each pair includes the same internal microphone and a different external microphone. For each pair of microphones, a process (i) receives a first audio signal of sound captured by the internal microphone and a second audio signal of sound captured by the different external microphone, (ii) estimates, using first and second audio signals, a radiation impedance, and (iii) computes a detection value based on the radiation impedance in a frequency band. A difference between (i) a currently computed detection value associated with a given pair of microphones and (ii) a previously computed detection value associated with said given pair, is computed. The sound produced by the cabinet is adjusted, in response to the computed difference meeting a threshold. Other embodiments are also described and claimed.
Low-Latency Audio Networking
Low-latency audio networking is disclosed. In one embodiment, an example playback device includes a processor and memory having stored thereon instructions executable by the processor. The example instructions are to cause the first playback device to perform functions comprising: receiving audio information; selecting a first frequency channel of a first spectrum based on a threshold latency associated with the audio information; transmitting to the second playback device via a second frequency channel of a second spectrum, control information that identifies the first frequency channel of the first spectrum; and transmitting to the second playback device via the first frequency channel of the first spectrum, the audio information to be played by the second playback device.

Sound processing unit, sound processing system, audio output unit and display device
Practical speaker connection is identified using a device having a sound channel of a 5.1 channel or 7.1 channel, and a device is provided that can easily reproduce the optimum multiple channels. Actual speaker arrangement can be identified by, for example, measuring the impedance of a terminal at the side of an audio amplifier. If incorrect connection is found, a warning is issued. This information is transmitted to a signal source with an EDID and a signal with the optimum a number of sound channel is sent. The EDID is also used for the connection with a display unit and the speaker connection with which the display unit is provided uniquely. For example, a sound through the 7.1 channel is easily reproduced using the speaker of the display unit in the channel of the front speaker.
