摘要： Example techniques may involve multiple calibrations for a playback device. In an example implementation, a first playback device, while playing back a first type of audio content via the one or more audio amplifiers configured to drive one or more speakers, applies a first calibration that offsets acoustic characteristics of a given environment when applied to playback by the first playback device. While playing back a second type of audio content via the one or more audio amplifiers configured to drive one or more speakers, the first playback device applies a second calibration that offsets acoustic characteristics of the given environment when applied to playback by the first playback device and calibrates the first playback device to one or more particular locations within the given environment.

摘要： Examples described herein involve detecting known impairments or other known conditions using a neural network. An example implementation involves receiving data indicating a response of a playback device as captured by a microphone. The implementation also involves determining an input vector by projecting a response vector that represents the response of the playback device onto a principle component matrix representing variance caused by one or more known impairments. The implementation further involves providing the determined input vector to a neural network that includes an output layer comprising neurons that correspond to respective known impairments. The implementation involves detecting that the input vector caused one or more neurons of the neural network to fire such that the neural network indicates that a particular known impairment is affecting the microphone and/or the playback device and adjusting operation of the playback device and/or the microphone to offset the particular known impairment.

摘要： The present disclosure provides an audio playing method and system for multiple playing devices. The method comprises: establishing a Bluetooth connection between a playing device and a terminal according to a connection request sent by the terminal; determining a playing group that the playing device belongs to according to play group information stored in the playing device; and receiving audio data sent by the terminal and syncing the audio data to other playing devices of the playing group, whereby all playing devices of the playing group will play the audio data synchronously. When a playing device of a music system received audio data via Bluetooth, some playing devices in the music system can be coordinated to process the audio data, and the listening experience of the user can be improved.

摘要： The invention relates to a loudspeaker system with power consumption control. The loudspeaker system comprises a powered audio bus, a bus driver connected to the powered audio bus where the bus driver feeds control information and audio information into the audio bus. The system further comprises loudspeaker nodes connected to the powered audio bus, where each of the nodes comprises a loudspeaker and an amplifier for driving the loudspeaker based on power from the audio bus, the control information and the audio information. The loudspeaker system further comprises a power consumption control arrangement arranged to reduce a power consumption of the loudspeaker nodes. The power consumption reduction may be obtained on basis of monitored parameters and may be performed for example by entering a standby mode, by reducing the bus voltage which powers the loudspeaker nodes, by reducing a switch frequency of the amplifiers and by other means.
