An example method includes receiving audio signals associated with virtual auditory space locations. Digital filters are selected based on the virtual auditory space locations. The digital filters include one or more notch filters including one or more center frequencies that are based on generally sigmoidal distributions of center frequencies as a function of virtual auditory space location. The notch filters are configured to produce one or more notches in frequency spectrums of audio signals when applied to the audio signals. The digital filters are applied to the audio signals to obtain processed audio signals. Output audio signals are generated based on the processed audio signals. The output audio signals are provided to devices for producing virtual auditory display sound.

An ear-mountable listening device includes an acoustic package and an electronics package. The acoustic package is configured to emit audio in response to an audio signal. The acoustic package includes a first set of magnets arranged annularly about a central axis of the ear-mountable listening device. The electronics package is electrically coupled to the acoustic package when the ear-mountable listening device is worn to provide the audio signal to the acoustic package. The electronics package includes a second set of magnets arranged annularly about the central axis proximate to a proximal end of the electronics package to removably affix the electronics package to the acoustic package via magnetic forces between the first set of magnets and the second set of magnets.

An ear-mountable listening device includes an array of microphones physically arranged into a ring pattern to capture sounds from an environment and output first audio signals that are representative of the sounds captured by the microphones. A speaker is arranged to emit audio into an ear in response to a second audio signal. Electronics are coupled to the array of microphones and the speaker and configured to capture the sounds with the array of microphones to generate the first audio signals and generate the second audio signal that drives the speaker based upon one or more of the first audio signals.

An ear-mountable listening device includes an adaptive phased array of microphones, a speaker, and electronics. The microphones are physically arranged into a ring pattern to capture sounds emanating from an environment. Each of the microphones is configured to output one of a plurality of first audio signals that is representative of the sounds captured by a respective one of the microphones. The speaker is arranged to emit audio into an ear. The electronics are coupled to the adaptive phased array and the speaker and include logic that when executed causes the ear-mountable listening device receive a user input identifying a first sound for cancelling or amplifying, steer a null or a lobe of the adaptive phased array based upon the user input, and generate a second audio signal that drives the speaker based upon a combination of one or more of the first audio signals.

Techniques described herein include generating first audio signals representative of sounds emanating from an environment and captured with an array of microphones disposed within an ear-mountable listing device. A rotational position of the array of microphones is determined. A rotational correction is applied to the first audio signals to generate a second audio signal. The rotational correction is based at least in part upon the determined rotational position. A speaker of the ear-mountable listening device is driven with the second audio signal to output audio into an ear.

An ear-mountable listening device includes a plurality of electroacoustic transducers, a manifold, and an output port. The plurality of electroacoustic transducers emit audio in response to an audio signal. The plurality of electroacoustic transducers includes a first transducer and a second transducer. The manifold is coupled to the plurality of electroacoustic transducers. The manifold is shaped to position the first transducer and the second transducer to face one another and form a front cavity disposed between the first transducer and the second transducer. The output port is coupled to the manifold to direct the audio from the front cavity into an ear when the plurality of electroacoustic transducers emits the audio.

In some embodiments, an ear-mounted sound reproduction system is provided. The system includes an ear-mountable housing that sits within the pinna of the ear and occludes the ear canal. In some embodiments, the ear-mountable housing includes a plurality of external-facing microphones. Because the external-facing microphones may be situated within the pinna of the ear but outside of the ear canal, the microphones will experience some, but not all, of the three-dimensional acoustic effects of the pinna. In some embodiments, sound is reproduced by an internal-facing driver element of the housing using a plurality of filters applied to the signals received by the plurality of external-facing microphones to preserve three-dimensional localization cues that would be present at the eardrum in the absence of the housing, such that the housing is essentially transparent to the user. In some embodiments, techniques are provided for deriving the plurality of filters.

A system for charging in-ear device battery packages includes a housing with a lid and a body, and a hinge system attaching the lid to the body. A charging unit is shaped to fit in the body, and includes a battery. One or more slots are disposed in the body that are exposed when the lid is open. The one or more slots are shaped to receive one or more of the in-ear device battery packages, and charge the one or more in-ear device battery packages with energy stored in the battery.

An in-ear device includes a molding shaped to hold the in-ear device in an ear, and an audio package configured to emit sound. The audio package is structured to removably attach to the molding. An electronics package is structured to removably couple to the audio package and removably attach to the molding.

An ear-mountable listening device includes a soft ear interface, an acoustic package, and electronics. The soft ear interface is shaped to house one or more components of the ear-mountable listening device. The soft ear interface has an outer surface that contacts a canal of an ear when the ear-mountable listening device is worn by the ear. The outer surface of the soft ear interface includes a plurality of baffles to form one or more channels for air or moisture to propagate through. The one or more channels extend from between a distal end and a proximal end of the soft ear interface. The proximal end of the soft ear interface extends to at least a first bend of the canal and the distal end of the soft ear interface contacts a concha of the ear when the ear-mountable listening device is worn.

An in-ear device includes a tympanic membrane measurement unit (TMMU) and an audio package configured to emit sound. The device is configured to measure a movement of a tympanic membrane in an ear using the TMMU caused by external sound received by the tympanic membrane, analyze at least the movement of the tympanic membrane measured by the TMMU using a predictive model trained by a machine learning technique to generate a waveform of cancellation sound that will destructively interfere with the external sound when received by the tympanic membrane, and output the cancellation sound from the audio package to destructively interfere with external sound received by the tympanic membrane.
