  • Patent number: 11902750
    Abstract: Systems and methods for arranging two first-order directional microphones in tandem to form a second-order directional microphone system of an amplified listening device are provided. The amplified listening device includes a first directional microphone configured to provide a first electrical signal having a first phase, and a second directional microphone reversed in space and configured to provide a second electrical signal having a second phase opposite the first phase. Microphone inlet ports of the first and second directional microphones are linearly aligned in a same plane. The rear microphone inlet ports of the first and second directional microphones are positioned adjacent each other. The amplified listening device includes a resistive summing circuit without phase inverting circuitry. The resistive summing circuit is configured to combine the first electrical signal and the second electrical signal to generate a second order directional response.

  • Patent number: 9566023
    Abstract: The present technology relates to an earphone apparatus adapted for use in audiometry examinations. The earphone apparatus comprises a housing and a receiver having an acoustic output adapted to connect with an audio signal source. The earphone apparatus can also include a circuit board with an electrical equalization network connected to the receiver. A coupling can be connected to the acoustic output of the receiver. A sound tube can be connected to the acoustic output and extends out from the housing to an ear piece. The earphone also includes a resonance cancellation assembly comprising a damping chamber and a tubing section acoustically connecting the damping chamber to the coupling. The damping chamber can provide an acoustic compliance to the sound delivered by the receiver. The earphone can also comprise an electrical connector with a protector that is adapted to connect with a female connector delivering electrical power.

  • Patent number: 9232292
    Abstract: Certain embodiments provide an in-the-ear device. The in-the-ear device includes a housing including a microphone inlet. The in-the-ear device also includes a microphone and a windscreen. The microphone is disposed within the housing adjacent to the microphone inlet. The windscreen includes a porous screen and an attachment mechanism coupled to the porous screen. The attachment mechanism is configured to detachably couple to the housing surrounding a perimeter of the microphone inlet such that an acoustic seal is formed between the windscreen and the housing.

  • Publication number: 20150047651
    Abstract: The present technology relates to a compact high fidelity earplug. The earplug has a central column having a hollow sound channel. Inner and outer platforms extend radially from the central column to define a first and second chamber. Openings in the first and second platforms allow sound to enter into the first chamber, and pass into the second chamber. Sound is then directed through an opening in the central column, into the sound chamber, and towards the ear of a wearer.
