  • Patent number: 11317188
    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.

  • Patent number: 9895097
    Abstract: Disclosed herein are apparatus and methods for delivering bone conduction stimuli for measuring the gravitation receptor functions of the inner ear. In some embodiments, a system may include (i) an impactor operatively linked to a guide disposed within a housing and (ii) an electrically driven actuator enclosed within the housing. The electrically driven actuator may be configured to cause the impactor to (i) travel to a striking point to deliver a mechanical bone conduction stimulus for transmission to a skull bone and (ii) controllably decelerate prior to the instance of stimuli delivery. The system may also include an oculometric response monitoring system including a video camera for capturing video of motion of one or more eyes of the patient.

  • Patent number: 9794704
    Abstract: A hearing aid apparatus is provided. In one embodiment, a system and method are provided for using a tympanostomy tube as a platform for driving the middle ear. The system and method may employ a mechanical interface for driving the middle ear. In another embodiment, a hearing aid apparatus includes a direct-drive hearing device (DHD) having a silicone mold on one end, where the silicone mold has an attached magnet; and a tympanostomy tube with a ferromagnetic cap, where the tympanostomy tube is insertable into a tympanic membrane. The DHD is configured for insertion in an ear canal such that the magnet attached to the silicone mold is in contact with the ferromagnetic cap of the tympanostomy tube.

  • Patent number: 9781526
    Abstract: Various methods and apparatus for processing audio signals are disclosed herein. The assembly may be attached, adhered, or otherwise embedded into or upon a removable oral appliance to form a hearing aid assembly. Such an oral appliance may be a custom-made device which can enhance and/or optimize received audio signals for vibrational conduction to the user. Received audio signals may be processed to cancel acoustic echo such that undesired sounds received by one or more intra-buccal and/or extra-buccal microphones are eliminated or mitigated. Additionally, a multiband actuation system may be used where two or more transducers each deliver sounds within certain frequencies. Also, the assembly may also utilize the sensation of directionality via the conducted vibrations to emulate directional perception of audio signals received by the user. Another feature may include the ability to vibrationally conduct ancillary audio signals to the user along with primary audio signals.
