Abstract: Systems and methods for authenticating a passive speaker include (i) activating, by a playback device configured to drive the passive speaker, a passive speaker identification circuit of the passive speaker by providing an identification signal to an input terminal of the passive speaker, wherein the passive speaker is a particular type of passive speaker having particular acoustic characteristics; (ii) while the passive speaker identification circuit is active, measuring, by the playback device, an electrical current of the identification signal; (iii) determining, based on the measured electrical current of the identification signal, an impedance modulation of the passive speaker; (iv) determining, by the playback device, the particular type of the passive speaker based on the impedance modulation of the passive speaker; and (v) applying, by the playback device, a calibration to the playback device based on the determined particular type of the passive speaker.

Abstract: Audio device transducers are disclosed herein. In some embodiments, the audio device transducer comprises a coil, first and second terminals each disposed adjacent a first side of the coil, and first and second conductors each electrically coupled to the coil. The first conductor extends from the first end of the coil to the first terminal, and the second end extends from a second end of the coil to the second terminal. The second conductor includes a first conductive pathway and a second conductive pathway spaced apart from the first conductive pathway such that the coil is disposed between the first conductive pathway and the second conductive pathway. In some embodiments, the first conductive pathway is symmetric to the second conductive pathway about an axis extending through the coil.

Abstract: Example techniques may involve performing aspects of a spatial calibration. An example implementation may include detecting a trigger condition that initiates calibration of a media playback system including multiple audio drivers that form multiple sound axes, each sound axis corresponding to a respective channel of multi-channel audio content The implementation may also include causing the multiple audio drivers to emit calibration audio that is divided into constituent frames, the multiple sound axes emitting calibration audio during respective slots of each constituent frame. The implementation may further include recording the emitted calibration audio. The implementation may include causing delays for each sound axis of the multiple sound axes to be determined, the determined delay for each sound axis based on the slots of recorded calibration audio corresponding to the sound axes and causing the multiple sound axes to be calibrated.

Abstract: Examples described herein involve validating motion of a microphone during calibration of a playback device. An example implementation involves a mobile device detecting, via one or more microphones, audio signals emitted from one or more playback devices as part of a calibration process. After the one or more playback devices emit the audio signals, the mobile device determines whether the detected audio signals indicate that sufficient horizontal translation of the mobile device occurred during the calibration process. When the detected audio signals indicate that insufficient horizontal translation occurred, the mobile device displays a prompt to move the mobile device more while the one or more playback devices emit one or more additional audio signals as part of the calibration process. When the detected audio signals indicate that sufficient horizontal translation occurred, the mobile device calibrates the one or more playback devices with a calibration based on the detected audio signals.

Abstract: Examples disclosed herein relate to playback device calibration. A calibration state variable may represent a calibration state of a playback device. A control device may display an indications of the calibration state. For instance, in a first instance, the control device may display an indication that a first playback device is in an uncalibrated state. Further, in a second instance, the control device may display an indication that the first playback device is in an calibrated state, perhaps after instructing the first playback device to initiate calibration.

Abstract: An example method is performed by a media playback system comprising a plurality of audio drivers configured to output audio content according to a first radiation pattern that produces an inherent directional effect. Based on data representing positions of one or more listeners in a listening area, the system determines first and second transfer functions corresponding to the first and second audio drivers, respectively. One or both of the transfer functions configure the first and second audio drivers to output audio content according to a second radiation pattern that produces a modified directional effect relative to the first radiation pattern. The system applies the transfer function to audio content thereby causing the first and second audio drivers to play back audio content according to the second radiation pattern.

Abstract: An example implementation may involve a control device receiving, from a first playback device of a media playback system, a calibration state variable indicating that the first playback device is uncalibrated. The control device may cause a graphical interface to display an indication that the first playback device is uncalibrated. The control device may also cause the graphical interface to display a selectable control that, when selected, initiates calibration of the first playback device. Based on detecting selection of the selectable control, the control device may initiate calibration of the first playback device.

Abstract: An example implementation may involve a control device displaying a prompt to initiate a calibration sequence that involves calibration of a playback device for a given environment in which the playback device is located. The example implementation may also involve the control device displaying (i) a prompt to prepare a playback device for calibration within a given environment, (ii) a prompt to prepare the given environment for calibration of the playback device, and/or (iii) a prompt to prepare the control device for calibration of the playback device. The example implementation may also involve a control device displaying a selectable control, that, when selected, initiates calibration of the playback device. The example implementation may further involve a control device initiating calibration of the playback device.
