  • Patent number: 11910156
    Abstract: Implementations of the subject technology provide an acoustic module with fins integrated within the acoustic module to reduce acoustic noise. Airflow caused by pressure changes due to an oscillating diaphragm can be diverted by the fins within the acoustic module. The diverted airflow provide a more uniform airflow distribution within the acoustic module, which leads to a lower peak velocity and less unwanted noise. Fins may include a curved or crescent shape and may be spaced in a certain manner to divert the airflow.

    Abstract: An audio system and method of spatially rendering audio signals that uses modified virtual speaker panning is disclosed. The audio system may include a fixed number F of virtual speakers, and the modified virtual speaker panning may dynamically select and use a subset P of the fixed virtual speakers. The subset P of virtual speakers may be selected using a low energy speaker detection and culling method, a source geometry-based culling method, or both. One or more processing blocks in the decoder/virtualizer may be bypassed based on the energy level of the associated audio signal or the location of the sound source relative to the user/listener, respectively. In some embodiments, a virtual speaker that is designated as an active virtual speaker at a first time, may also be designated as an active virtual speaker at a second time to ensure the processing completes.

  • Patent number: 11832084
    Abstract: Embodiments relate to an audio system that performs equalization of audio signals based on one or more diffuse field head-related transfer functions (HRTFs) and device-specific data. User-specific data and device-specific data (i.e., transducer-specific data) are applied to an acoustic model to predict an acoustic response for a user. An equalization filter is then determined using the acoustic response and the one or more diffuse field HRTFs. The equalization filter is applied to a processed version of an audio signal to create a modified version of the audio signal. The modified version of the audio signal is presented to the user via a transducer array of the audio system. The audio system can further include a microphone assembly that reduces the Helmholtz resonance effect.
