  • Patent number: 10440491
    Abstract: Embodiments described herein reduce latency and improve packet delivery when transmitting audio packets from a source device to one or more sink devices. For example, one or more operating modes that introduce latency when transmitting packets may be disabled at the source device and/or sink device(s). Additionally, certain operational behavior of the source device and/or sink device(s) may be changed based on the quality of the channel used to transmit audio packets to further improve the latency. Such operational behavior includes changing the jitter buffer size of the sink device(s), the number of retry attempts performed by the source device when re-transmitting packets that have been lost, and changing the channel used to transmit the audio packets. Embodiments described herein further enable the synchronization of playback between the sink devices to ensure that sink devices playback audio packets in a synchronized fashion.

  • Patent number: 10440467
    Abstract: A method for controlling a vehicle relates to a voice masking technology for allowing only a specific passenger among passengers in the vehicle to listen to a voice communication signal such as a dial tone, and the technology inhibits the remaining passengers other than the specific passenger from listening to the voice communication signal. The vehicle includes a voice signal receiver to receive a voice signal, a speaker provided in the vehicle to output the voice signal, and a controller to perform frequency conversion of the received voice signal. In particular, the controller generates a masking sound for inhibiting transmission of information contained in the voice signal on the basis of a frequency band of the converted voice signal, and generates a control signal in a manner that the generated masking sound is output to a predetermined region of an indoor space of the vehicle.

  • Patent number: 10431238
    Abstract: A digital processor-based memory-efficient and computation-efficient audio signal processing technique partitions each of two audio signals into shorter segments and combines the shorter segments into combined segments. A processor cross-correlates the first combined segment and the second combined segment into a cross-correlation result, which is written into a cross-correlation array. The result may be used for delay estimation (to estimate the relative delay between the two audio signals.) Other aspects are also described and claimed.

  • Patent number: 10397724
    Abstract: One embodiment provides a method comprising determining an actual elevation of a sound source. The actual elevation is indicative of a first location at which the sound source is physically located relative to a first listening reference point. The method further comprises determining a desired elevation for a portion of an audio signal. The desired elevation is indicative of a second location at which the portion of the audio signal is perceived to be physically located relative to the first listening reference point. The desired elevation is different from the actual elevation. The method further comprises, based on the actual elevation, the desired elevation and the first listening reference point, modifying the audio signal, such that the portion of the audio signal is perceived to be physically located at the desired elevation during reproduction of the audio signal via the sound source.

  • Patent number: 10397693
    Abstract: An acoustic enclosure has a housing at least partially defining an acoustic chamber for an acoustic radiator. The housing defines an acoustic port from the acoustic chamber to a surrounding environment. An acoustic resonator has a first resonant chamber and a second resonant chamber. The acoustic resonator also has a first duct to acoustically couple the first resonant chamber with the acoustic chamber and a second duct to acoustically couple the second resonant chamber with the first resonant chamber. An electronic device can have an electro-acoustic transducer. Circuitry in the electronic device can drive the electro-acoustic transducer to emit sound over a selected frequency bandwidth. Damping provided by the first and the second resonant chambers can de-emphasize one or more frequencies and/or extend a frequency response of the acoustic enclosure to improve perceived sound quality emitted by the electronic device.

  • Patent number: 10388292
    Abstract: A method for compressing a HOA signal being an input HOA representation with input time frames (C(k)) of HOA coefficient sequences comprises spatial HOA encoding of the input time frames and subsequent perceptual encoding and source encoding. Each input time frame is decomposed (802) into a frame of predominant sound signals (XPS(k?1)) and a frame of an ambient HOA component ({tilde over (C)}AMB(k?1)). The ambient HOA component ({tilde over (C)}AMB(k?1)) comprises, in a layered mode, first HOA coefficient sequences of the input HOA representation (cn(k?1)) in lower positions and second HOA coefficient sequences (cAMB,n(k?1)) in remaining higher positions. The second HOA coefficient sequences are part of an HOA representation of a residual between the input HOA representation and the HOA representation of the predominant sound signals.

  • Patent number: 10382850
    Abstract: The present disclosure relates to a spring sheet, an electroacoustic device and an electronic device. The spring sheet, for an electroacoustic device including a holder and a magnetic unit accommodated in the holder, includes: a main body, the main body comprising a magnetic unit fixing portion and a holder fixing portion; wherein the magnetic unit fixing portion is configured to be fixedly connected with the magnetic unit, the holder fixing portion is configured to be fixedly connected with the holder, and the main body is shaped in a non-circular enclosed ring structure. By such configuration, the spring sheet can be applied in a non-circular three-in-one product, and stress of the spring sheet can be effectively dispersed, which can fundamentally solve the problem that the arm of force of the spring sheet deforms and lose efficacy when the product falls off, thereby extending service life of the spring sheet.

  • Patent number: 10369057
    Abstract: A wireless audio system suppresses exterior noise and directs desired sound into a user's ear canal. An audio system may include an earplug to create a seal in the interior of an ear canal. The earplug may include a ribbed exterior profile and can be flexible to create the seal. A speaker may be inserted within the earplug. A channel may extend through a body of the earplug to direct sound into a user's ear canal. A proximal opening may extend from the speaker to the channel of the earplug, and an audio wire may be connected to the speaker. The audio wire may connect to a wireless receiver, or other receiver, to allow audio data to pass through the wire and to the speaker, where it can be converted to audio that is passed directly into the ear canal of the user.
