  • Patent number: 11259138
    Abstract: In one embodiment, a method for determining a dynamic head-related transfer function for a subject includes receiving audio recordings of a sound captured by audio sensors. The sound is emitted by an in-ear speaker worn by the subject. Additionally, a reference signal captured by a microphone coupled to the in-ear speaker and one or more images captured by image sensors are received. The one or more images depict a body pose of the subject while the sound is emitted by the in-ear speaker and may be used to generate a pose representation of the body pose of the subject. A head-related transfer function for each audio sensor is determined based on the pose representation, the audio recordings of the sound, and the reference signal. The dynamic head-related transfer function is determined based on the head-related transfer function for each audio sensor.

  • Publication number: 20210297763
    Abstract: In one embodiment, a method for emitting a sound from an in-ear speaker worn by a subject includes generating, by an audio source of the in-ear speaker, a source audio signal. One or more speakers of the in-ear speaker may emit a sound based on the audio signal and an audio-transport tube of the in-ear speaker may receive the sound. The one or more speakers may be comprised of a singular speaker or a speaker array coupled to a crossover network. The audio-transport tube has an input end coupled to the one or more speakers to receive the sound. An audio reflector of the in-ear speaker may reflect the sound. The audio reflector is coupled to an output end of the audio-transport tube.
