  • Patent number: 10658995
    Abstract: Calibration of a headset that uses bone conduction to provide audio content to a wearer is presented. A first tone of a plurality of tones that are at different frequencies is presented to the wearer via an air conduction transducer. A corresponding tone having a same frequency as the first tone is also presented to the wearer via a bone conduction (BC) transducer. The corresponding tone is adjusted such that a level of loudness is within a threshold range of a level of loudness of the first tone. An ear-canal sound pressure (ECSP) resulting from the first tone is recorded and a voltage applied to the BC transducer for generating the adjusted corresponding tone. An equalization filter is generated based in part on the ECSP and the voltage, the equalization filter for filtering an audio signal for presentation via the BC transducer.

  • Publication number: 20200154195
    Abstract: A method for manufacturing a cartilage conduction audio device is disclosed. A manufacturing system receives data describing a three-dimensional shape of an ear (e.g., the outer ear, behind the ear, the concha bowel, etc.) of a user. The system identifies one or more locations for one or more transducers along a back of an auricle of the ear for the user that vibrate the auricle over a frequency range causing the auricle to create an acoustic pressure wave at an entrance of the ear canal. The system then generates a design for a cartilage conduction audio device for the user based on the one or more identified locations of the transducers at which acoustic pressure waves generated by the one or more transducers satisfy a threshold performance metric for the user. The design may then be used to fabricate the cartilage conduction audio device.

  • Patent number: 10616692
    Abstract: An audio system includes a transducer assembly, an optical sensing pathway, a laser, a detector assembly, and a controller. The transducer assembly is coupled to a user's ear and produces an acoustic pressure wave based on an audio instruction. The optical sensing pathway moves, at least in part, with a detected acoustic pressure wave. The laser emits light that is separated into a reference beam and a sensing beam that is coupled into the optical sensing pathway. The detected acoustic pressure wave interacts with the sensing beam to alter its optical path length. The detector assembly detects the reference and sensing beams from the optical sensing pathway, and measures the detected acoustic pressure wave based on changes in optical path length between the reference beam and the sensing beam. The controller adjusts the audio instruction based on the measurement of the detected acoustic pressure wave.

  • Patent number: 10531173
    Abstract: A tragus conduction apparatus may include a sound transducer positionable against a tragus of a user's ear to mechanically vibrate the tragus to produce one or more sound waves that travel down an ear canal of the user's ear toward an eardrum. A wearable device may include a tragus conduction apparatus and a wearable frame dimensioned to adjustably hold the tragus conduction apparatus at the user's ear. Various other apparatuses, systems, and methods are also disclosed.

  • Publication number: 20190342647
    Abstract: An audio system for providing content to a user. The system includes a first and a second transducer assembly of a plurality of transducer assemblies, an acoustic sensor, and a controller. The first transducer assembly couples to a portion of an auricle of the user's ear and vibrates over a first range of frequencies based on a first set of audio instructions. The vibration causes the portion of the ear to create a first range of acoustic pressure waves. The second transducer assembly is configured to vibrate over a second range of frequencies to produce a second range of acoustic pressure waves based on a second set of audio instructions. The acoustic sensor detects acoustic pressure waves at an entrance of the ear. The controller generates the audio instructions based on audio content to be provided to the user and the detected acoustic pressure waves from the acoustic sensor.

  • Publication number: 20190253811
    Abstract: The present invention is adapted to assist in optimizing the performance of a hearing aid by detecting conditions which result in sub-optimal performance and assisting a user or health care professional to correct those conditions. The present invention is adapted to optimize the performance of a hearing aid by generating a reference signal which, when broadcast, creates a feedback signal. The feedback signal is then measured, or its characteristics identified, to determine whether the hearing aid system is optimized and, if not, what components or characteristics are not optimized and how to optimize the hearing aid system performance or that of its components.
