Patent number: 11902750Abstract: 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.

Patent number: 9566023Abstract: 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.Type: GrantFiled: October 8, 2014Date of Patent: February 14, 2017Assignee: ETYMOTIC RESEARCH, INC.Inventors: Mead C.
