Abstract: Example techniques may involve calibration with multiple recording devices. An implementation may include a mobile device receiving data indicating that a calibration sequence for multiple playback devices has been initiated in a venue. The mobile device displays a prompt to include the first mobile device in the calibration sequence for the multiple playback devices and a particular selectable control that, when selected, includes the first mobile device in the calibration sequence. During the calibration sequence, the mobile device records calibration audio as played back by the multiple playback devices and transmits data representing the recorded calibration audio to a computing device.

Abstract: Embodiments are described herein that involve receiving, by a social-media computing system from a media playback system, playback data indicating media that is being played back by the media playback system, where the playback data comprises an indication of at least one zone of the media playback system in which the media is being played back; and based on the received playback data, updating social-media data in a social-media account, where the updated social-media data comprises an indication of the at least one zone in which the media is currently being played back.

Abstract: Disclosed herein are devices (e.g., audio playback devices) configured to transmit and/or receive wireless power. Wireless power can be transferred using mid-range or long-range techniques, such as electromagnetic radiation (e.g., lasers, microwaves) or electromagnetic coupling (e.g., inductive coupling, capacitive coupling). Device performance and/or power transmission may be modified dynamically based on wireless power levels, user behavior, the behavior of other devices, device grouping, or other parameters.

Abstract: As noted above, example techniques relate to playback transitions between platforms. In an example implementation, while a first playback device is playing back audio content during a first playback session in a first domain, a mobile device detecting a first event configured as a trigger to transfer playback to a second domain on a second playback device. In response to detecting the first event, the mobile device determining playback information for the playback session and sends, via a network interface, instructions to initiate a playback session in the second domain to reproduce the first playback session in the first domain.

Abstract: Example techniques relate to playback based on acoustic signals in a system including a first network device and a second network device. A first network device may detect a presence of a user using a camera and/or infrared sensors. The first network device sends, in response to detecting the presence of the user, a particular signal via the first network interface. The second network device receives data corresponding to the particular signal and plays back an audio output corresponding to the particular signal.

Abstract: Disclosed example configurations include a playback device configured to, among other features, (i) receive reference clock timing; (ii) receive two or more data streams, where each data stream includes audio content and playback timing; (iii) for each data stream, generate sample-rate adjusted audio content for the data stream by adjusting a sample rate of at least a portion of the audio content of the data stream to compensate for a difference between a rendering clock at the playback device and the reference clock; (iv) generate a mix of the sample-rate adjusted audio content of the two or more data streams at the playback device; and (v) play the mix of the sample-rate adjusted audio content of each data stream based on a clock time of the rendering clock at the playback device and the playback timing information for each data stream.

Abstract: In one aspect, a playback device is configured to (i) receive a first stream of audio data representing audio content from a computing system, (ii) detect an indication that a source of the audio content is to switch from the computing system to a user device; (iii) after detecting the indication, establish a point-to-point wireless link with the user device over which to receive a second stream of audio data; (iv) receive the second stream of audio data representing the audio content; (v) determine a future time at which to transition from playing back the audio content using the first stream of audio data to playing back the audio content using the second stream of audio data; and (vi) at the future time, transition from playing back the audio content using the first stream of audio data to playing back the audio content using the second stream of audio data.

Abstract: A speaker device (101, 201, 301) comprising a first diaphragm (103, 203, 303), an opposing second diaphragm (104, 204, 304), and a frame (102, 202, 302) comprising a first frame part (102a, 202a) on which the first diaphragm (103, 203, 303) is mounted and an opposing second frame part (102b, 202b) on which the second diaphragm (104, 204, 304) is mounted. A first speaker driver (105, 205, 305) drives the first diaphragm (103, 203, 303) and a second speaker driver (106, 206, 306) drives the second diaphragm (104, 204, 304). The first frame part (102a, 202a), a movable first coil bracket (107) of the first speaker driver (105, 205, 305), and a resilient first damper member (111) form a first single piece integrally formed unitary component. The second frame part (102b, 202b), a moveable second coil bracket (109) of the second speaker driver (106, 206, 306) and a resilient second damper member (112) form a second single piece integrally formed unitary component.

Abstract: Example techniques described herein involve a scent diffusing system. The system can include scent diffusing device(s), playback device(s), and controller device(s). The controller device may display on a graphical interface a representation of a first scent diffusing device and receive one or more inputs selecting the representation of the first scent diffusing device and a particular scent for the first scent diffusing device to release. At least one setting for the particular scent may be displayed which may include a scent release time. A selection of the at least one setting may be received, and the controller device may send a message to the first scent diffusing device including information indicating the scent to release and the selected at least one setting. The controller device can cause the first scent diffusing device to release the particular scent at the release time.

Abstract: In one aspect, a playback device includes a voice assistant service (VAS) wake-word engine and a command keyword engine. The playback device detects, via the command keyword engine, a first command keyword, and determines whether one or more playback conditions corresponding to the first command keyword are satisfied. Based on (a) detecting the first command keyword and (b) determining that the one or more playback conditions corresponding to the first command keyword are satisfied, the playback device playback device performs a first playback command corresponding to the first command keyword. When the playback device detects, via the wake-word engine, a wake-word in voice input, the playback device streams sound data corresponding to at least a portion of the voice input to one or more remote servers associated with the VAS.

Abstract: Example techniques may involve guest access to a media playback system. A guest may use a guest control device, such as a smartphone or tablet, to control aspects of a host's media playback system. In addition, the guest may temporarily register their user account of a streaming audio service with the host's media playback system, which enables playback of audio content from that service by one or more playback devices of the media playback system. When the guest control device de-registers from the host's media playback system, retrieval of audio content from the streaming audio service is disabled.

Abstract: A negative-stiffness audio transducer can include a frame, a voice coil, and a suspension assembly resiliently attaching the voice coil to the frame. The suspension assembly provides a negative stiffness to axial movement of the voice coil. The transducer further includes a diaphragm coupled to the voice coil such that the voice coil moves the diaphragm in an axially inward direction or an axially outward direction in response to an electrical signal. A stabilizer can be used to selectively move the diaphragm axially inward or outward to maintain the audio transducer in an operational state.
