  • 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.
