  • Patent number: 11770670
    Abstract: The present disclosure relates to systems, methods, and non-transitory computer-readable media that present spatial audio using the speakers of a wearable audio device and speakers external to the wearable audio device. In particular, in one or more embodiments, the disclosed systems generate spatial audio having a high-frequency component and a low-frequency component. The disclosed systems further generate cross-talk cancellation filters for the low-frequency component of the spatial audio. The disclosed systems can provide the high-frequency component for presentation via speakers of the wearable audio device and the low-frequency component for presentation via the external speakers using the cross-talk cancellation filters. In some cases, the disclosed systems generate the spatial audio or the cross-talk cancellation filters using a personalized interaural display model and/or head-related transfer functions.

    Abstract: Embodiments relate to calibrating head-related transfer functions (HRTFs) for a user of an audio system (e.g., as a component of a headset) using cartilage conducted sounds. A test sound is presented to a user using a transducer (e.g., cartilage conduction) and an audio signal is responsively received via a microphone at an entrance to the user's ear canal. The test sound and audio signal combination may be provided to an audio server where a model is used to determine one or more HRTFs for the user. Information describing the one or more HRTFs is provided to the audio system to be used for providing audio to the user. The audio server may also use a model to determine geometric information describing a pinna of the user based on the combination. In one embodiment, the geometric information is used to determine the one or more HRTFs for the user.

  • Patent number: 11240588
    Abstract: Provided is an ear-hole open type sound reproducing apparatus which can obtain good sound quality over a wide band while adopting a bone conduction system. A first equalizer 303 removes a high range component which is difficult to be reproduced by a vibration speaker 301 and is hard to be conveyed by bone conduction. Then, the vibration speaker 301 outputs the sound over a low range to a middle range by bone conduction sound. By equalizing processing of the first equalizer 303, it is also possible to reduce sound leakage of the high range. On the other hand, a second equalizer 304 removes components over the low range to the middle range. Then, an air conduction speaker 302 outputs high quality sound of the high range component by air conduction sound.
