  • Patent number: 11184706
    Abstract: An apparatus and method of excursion protection of a loudspeaker. The method includes attenuating selected bands in a transform domain, controlled by a feedback signal resulting from an excursion transfer function that has been modified according to the real-time operational characteristics of the loudspeaker. In this manner, the system reduces the amount of wideband attenuation needed to address the predicted excursion, resulting in a better listening experience.

  • Patent number: 11178475
    Abstract: An assembly may include a speaker supportable for movement relative to a reference external to the speaker and a speaker housing supporting speaker components operable to produce an audio output. A sensor is operable to sense a direction of movement of the speaker during movement of the speaker relative to the reference. Control components are operable to control the speaker components based on the direction of movement of the speaker relative to the reference. When the speaker is sensed to be moving in a first direction relative to the reference, an operational characteristic of the speaker components is controlled to increase or advance during movement in the first direction. When the speaker is sensed to be moving in a second direction relative to the reference different from the first direction, the operational characteristic of the speaker components is controlled to decrease or retreat during movement in the second direction.

  • Patent number: 11134337
    Abstract: A microphone assembly for providing improved directivity at high and low frequencies is disclosed. The microphone assemblies comprise two waveguides each having a microphone, a high-frequency port, and a low-frequency port. The two waveguides are arranged adjacent to each other so that the two low-frequency ports are arranged at a first distance apart from each other and so that the two high-frequency ports are arranged at a second distance apart from each other. The microphone assemblies may comprise two additional waveguides of different length than the first two waveguides, where the two additional waveguides also have low frequency ports and high frequency ports. When the four waveguides are arranged adjacent to each other, all the low-frequency ports are at one distance from each other and all the high-frequency ports are at another distance from each other.

  • Patent number: 11128977
    Abstract: Channels of audio data in a spatial audio object are associated with any one or more of a direction and a location of one or more recorded sounds, which channels are to be reproduced as spatial sound. A visualized spatial sound object represents a snapshot/thumbnail of the spatial sound. To preview the spatial sound (by experiencing its snapshot or thumbnail), a user manipulates the orientation of the visualized spatial sound object, and a weighted downmix of the channels is rendered for output as a spatial preview sound, e.g., a single output audio signal is provided to a spatial audio renderer; one or more of the channels that are oriented toward the user are emphasized in the preview sound, more than channels that are oriented away from the user. Other aspects are also described and claimed.

  • Patent number: 11082769
    Abstract: An audio system and method for enhancing audio quality in telecommunications applications. Specifically, a graphical user interface (GUI) is provided to allow an observer to visualize pickup zones within an environment that schematically represent areas of heightened microphone sensitivity. A microphone array and camera are arranged to obtain an audio signal and an image which correspond to a talker within the environment. The images are displayed via a first device or are transmitted to a second device and are displayed to the observer, while the audio signal is converted into an audio output by the second device. Visual overlays are provided, via the visualization window, corresponding with pickup zones within the environment corresponding to areas of heightened microphone sensitivity. The observer may adjust the visual overlay corresponding with each pickup zone using the GUI provided, resulting in an adjustment of the pickup zones by the microphone array within the environment.

  • Patent number: 11070933
    Abstract: A computer system having an electronic device determines a listener position within a computer-generated reality (CGR) setting that is to be aurally experienced by a user of the electronic device through at least one speaker. The system determines a source position of a virtual sound source within the CGR setting and determines a characteristic of a virtual object within the CGR setting, where the characteristic include a geometry of an edge of the virtual object. The system determines at least one edge-diffraction filter parameter for an edge-diffraction filter based on 1) the listener position, 2) the source position, and 3) the geometry. The system applies the edge-diffraction filter to an input audio signal to produce a filtered audio signal that accounts for edge-diffraction of sound produced by the virtual sound source within the CGR setting.
