  • Patent number: 10299055
    Abstract: Examples described herein involve configuring a playback device based on distortion, such as that caused by a barrier. One implementation may involve causing the playback device to play audio content according to an existing playback configuration, determining an existing frequency response of the playback device in a given system, and determining whether a difference between the existing frequency response of the playback device in the given system and a predetermined frequency response for the playback device is greater than a predetermined distortion threshold. If it is determined that the difference between the existing frequency response of the playback device and the predetermined frequency response for the playback device is greater than the predetermined distortion threshold, then the existing playback configuration of the playback device is changed to an updated playback configuration of the playback device and the playback device plays audio content according to the updated playback configuration.

  • Publication number: 20190098400
    Abstract: Systems and methods for three-dimensional beamforming disclosed herein include, among other features (i) generating a set of received-sound beams by applying a plurality of sets of beamforming coefficients stored in a tangible memory of the network device to sound received via a microphone array of the network device, wherein each received-sound beam corresponds to a separate direction relative to the microphone array, (ii) identifying a subset of the received-sound beams comprising speech content, (iii) for each received-sound beam in the subset of the received-sound beams comprising speech content, determining whether the speech content comprises a wake word, (iv) selecting one final received-sound beam from the received-sound beams in the subset of the received-sound beams determined to comprise a wake word; and (v) causing the selected one final received-sound beam to be processed to identify a voice command.

  • Publication number: 20190037305
    Abstract: Example techniques may involve reduction of turbulence noise from a sound transducer that is mounted within an interior housing of a playback device. An example playback device may include an enclosure comprising a first interior volume and a second interior volume. The playback device may further include a speaker mounted within an interior of the enclosure. The speaker includes a diaphragm dividing the first interior volume and the second interior volume and the speaker is moveable along an axis to generate sound. The playback device may also include a first speaker vent providing airflow between the first interior volume and an exterior of the enclosure and a second speaker vent providing airflow between the first interior volume and the exterior of the enclosure. The first speaker vent directs airflow in a first direction and second speaker vent directs airflow in a second direction.

  • Patent number: 10129641
    Abstract: A system for tuning an audio reproduction device is disclosed. The system includes an audio signal generator for generating an audio signal to be played back in an audio reproduction device and sending the audio signal to the audio reproduction device; a microphone signal module for receiving a microphone signal from a microphone, the microphone signal recording a sound wave reproduced by the audio reproduction device when the audio signal is played back in the audio reproduction device; a comparison module for determining whether the microphone signal matches target sound signature data; and a filter module for applying a digital filter to emulate a target sound signature responsive to determining that the microphone signal does not match the target sound signature data.

  • Publication number: 20180213316
    Abstract: An earphone is disclosed having a first housing including a first housing mounting plane and a central axis normal to the first housing mounting plane, a second housing mounted to the first housing, a speaker mounted on the first housing, wherein the speaker defines a speaker axis, and a nozzle having a nozzle axis and extending from the first housing. The normal angle between the speaker axis and the first housing mounting plane defines a speaker axis angle and the normal angle between the nozzle axis and the first housing mounting plane defines a nozzle axis angle. In one embodiment, the speaker axis angle is greater than the nozzle axis angle.

  • Patent number: 10028047
    Abstract: Headphones include removable audio drivers electrically coupled with electrical conductors using solderless and detachable interconnections. Driver assemblies for headphones include an audio driver and a driver unit housing. An acoustical cavity is defined between the driver unit housing and the audio driver, and a port extends through the driver unit housing between the acoustical cavity and the exterior of the driver assembly. The driver unit housing is configured to be secured within an outer ear-cup housing of a headphone such that the port is open to the exterior of the headphone without communicating acoustically with a volume outside the driver unit housing and within the outer ear-cup housing. Headphones include such driver assemblies. Methods are used to form such headphones and driver assemblies.

  • Publication number: 20180098140
    Abstract: A grill cover that fits over or is positioned over high frequency acoustical regions and low frequency acoustical regions of a playback device. A portion of the grill cover that fits over or is positioned over a high frequency acoustical region has small area openings and a portion of the grill over a low frequency acoustical region has large area openings. In portions of the grill cover between the portions over high and low frequency acoustical regions, the openings may have an intermediate area to visually blur the differences between the portions of the grill covers. To further blur the differences, the differently sized openings may be interleaved.
