    Abstract: The present disclosure describes a multi-mode headset incorporating both bone conduction and aural transducers. Bone conduction plates of the headset rest on a users' temples, just in front of each ear in one implementation, and create sound through vibrations in a first mode, allowing the user to listen to the headset while still leaving environmental or external sounds audible. In a second mode, the user detaches aural transducers or earbuds from an attachment point and inserts them into the user's ears, blocking external noise and providing passive and/or active noise isolation. In a third mode, both the bone conduction plates and aural transducers may be used simultaneously, providing additional amplitude and potentially wider frequency response. The headset may include a switch, such as a magnetic proximity sensor detecting the position of the aural transducers, to control a mixer or amplifier to re-route audio through the aural transducers.

    Abstract: Embodiments relate to crosstalk cancellation to reduce crosstalk vibrations during use of multiple bone conduction transducers. A system, for example, a head-mounted display (HMD) for providing audio to a user, uses vibration sensors to detect vibrations caused by the bone conduction transducers. In particular, a vibration sensor may generate an error signal representing residual vibrations due to crosstalk at a given ear region of the user. The system uses estimated transfer functions for noise propagation paths through the user's head to generate an anti-crosstalk signal. In response to the anti-crosstalk signal, a bone conduction transducer transmits anti-crosstalk vibrations that reduce the error signal at the given ear region.

  • Patent number: 9997173
    Abstract: A method performing automatic gain control (AGC) using an accelerometer in a headset starts with an accelerometer-based voice activity detector (VADa) generating a VADa output based on (i) acoustic signals received from at least one microphone included in a pair of earbuds and (ii) data output by at least one accelerometer that is included in the pair of earbuds. The at least one accelerometer detects vibration of the user's vocal chords. The headset includes the pair of earbuds. An AGC controller then performs automatic gain control (AGC) on the acoustic signals from the at least one microphone based on the VADa output. Other embodiments are also described.

  • Patent number: 9989434
    Abstract: Certain embodiments provide a system and method for measurement of the force applied to a bone-conduction oscillator during application to a subject, resolving the measured force relative to a pre-determined criteria, and providing an indication to the user to specify whether an external force applied to an applied force indication system coupled with a bone-conduction oscillator is within a pre-determined acceptable range. A mechanical arrangement is prescribed which allows the full extent of the force applied to be represented onto the pressure measurement apparatus. The system and apparatus may be applied onto or integrated into bone-conduction oscillators.

  • Patent number: 9943712
    Abstract: A communication and speech enhancement system featuring a first transducer designed to be temporarily affixed to a human such as a hospital patient to convert the audible vibrations of human speech into an electrical signal. The transducer provides this electrical signal to one or more electronic modules which modify and enhance the signal. The enhanced signal may then be amplified and converted back into audible sound by means of a second transducer. A user of the system controls the electronic modules through a user interface. In an embodiment, one or both of the user interface and second transducer feature smooth surfaces amenable to cleaning sterilizing with liquid agents.

  • Patent number: 9877121
    Abstract: A button on an auditory prosthesis is aligned with a shaft and a bone anchor of the prosthesis. Forces resulting from pressing of the button are evenly distributed towards the anchor, which prevents damage to the prosthesis. The button can be connected to the prosthesis housing with a flexible element or seal, which acts as a soft mute function when the button is pressed, further reducing the risk of feedback. Dampers can be incorporated into the button structure to further dampen feedback that can be transmitted to other components of the auditory prosthesis.
