Patent number: 10932069Abstract: Acoustic valves include a housing having an acoustic inlet, an acoustic outlet, and an acoustic passage between the inlet and the outlet. An electrical coil is disposed in the housing and configured to generate a magnetic field when energized by an actuation signal. A spring is coupled to an armature movably disposed in the housing between a first surface and a second surface. The valve has a first stable state wherein the armature is positioned against one surface when the electrical coil is not energized, and the valve has a second stable state wherein the armature is positioned against the other surface when the electrical coil is not energized. The armature is movable between the first and second states when the electrical coil is energized, wherein the acoustic passage is more obstructed when the armature is in one state than when the armature is in the other state.Type: GrantFiled: April 11, 2019Date of Patent: February 23, 2021Assignee: Knowles Electronics, LLCInventors: Christopher Jones, Christopher Monti, Shehab Albahri

Patent number: 10869141Abstract: Methods and apparatus determine the actual state of one or more acoustic valves e.g., whether an acoustic valve is open or closed, in a hearing device. A sensor in the hearing device is configured to generate an output signal indicative of a state of the acoustic valve. An electrical circuit actuates the acoustic valve if the actual state is different than a desired state. The determination of the state of the acoustic valve can be done on the hearing device or on a remote device.Type: GrantFiled: December 30, 2018Date of Patent: December 15, 2020Assignee: Knowles Electronics, LLCInventors: Shehab Albahri, Christopher Monti, Thomas Miller, Charles King

Publication number: 20200213731Abstract: Methods and apparatus change operation of a hearing device based on a state of an acoustic valve in the hearing device. In some examples an electrical circuit performs one or more of differing operations depending on a state of the acoustic valve. Some operations change the signal to a sound producing transducer and other operations change other operations of the hearing device. For example, an electrical circuit changes active noise cancelling operation, changes equalization settings, provides noise reduction improvements, provides beam forming changes and other operations based on a state of the acoustic valve. In some implementations, a change in acoustic valve state is used to change the operation of the hearing device.Type: ApplicationFiled: December 31, 2018Publication date: July 2, 2020Inventors: Thomas Miller, Shehab Albahri, Andrew Bellavia, Erik Wiederholtz, Christopher Monti

Patent number: 10687153Abstract: The present disclosure pertains to hearing devices configurable between open fit and closed fit configurations at different times through actuation of one or more acoustic valves located in one or more corresponding sound passages of the hearing device. The one or more acoustic valves of the hearing device are adaptively controlled based on context detected by one or more sensors. The context may be, but is not limited to, a mode of operation of the hearing devices which may include, for example, an audio content playback mode and a voice communication mode. The actuatable valves may be actuatable in situ without having to remove the hearing device from the user's ear thereby enabling the user to experience the benefit of a closed fit or an open fit depending on the user's desire or other context.Type: GrantFiled: December 30, 2018Date of Patent: June 16, 2020Assignee: Knowles Electronics, LLCInventors: Shehab Albahri, Christopher Monti, Thomas Miller, Charles King, Christopher Jones, Brenno Varanda, Erik Wiederholtz
