  • Patent number: 11102576
    Abstract: 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.

  • Patent number: 11070904
    Abstract: An earphone includes a housing that defines a force input surface opposite a touch input surface. A spring member in the housing includes a first arm that biases a touch sensor toward the touch input surface. The spring member also includes a second arm that biases a first force electrode toward the housing and allows the first force electrode to move toward a second force electrode when a force is applied to the force input surface. A non-binary amount of the force is determinable using a change in a mutual capacitance between the first force electrode and the second force electrode. The mutual capacitance between the first force electrode and the second force electrode may be measured upon detecting a touch using the touch sensor.

  • Patent number: 11044540
    Abstract: A variable waveguide speaker controls, narrows, and directs the dispersion of the lower driver array to handle far-field listening areas. The widening mid-section of the speaker directs the sound from the mid-driver array to mid-field listening areas. The top of the speaker is the widest, allowing the top array drivers to cover their widest dispersion for near-field listening areas. This form-follows-function design results in a modern shape and elegant enclosure, as well as superior audio performance. A unique laminar flow grill system consisting of a multi-layer sandwich arrangement protects the speaker components from performance damage UV rays, dust, debris, water and ice.
