Definitions

  • This document relates generally to hearing assistance systems and more particularly to methods and apparatus for increasing antenna performance for wireless hearing assistance devices.
  • Modern hearing assistance devices such as hearing aids, are electronic instruments worn in or around the ear that compensate for hearing losses by specially amplifying sound.
  • Some hearing aids include an antenna for radio frequency (RF) communications.
  • Antenna performance can be affected by coupling of the antenna system with conductors of an audio receiver, which creates a flow of high frequency current through the audio receiver wires, causing the wires to become an RF radiator. This coupling between the antenna and the audio receiver cables can cause a variance in RF gain which can create wireless link performance problems.
  • US2009/0196444 A1 shows a RIC type hearing aid, wherein the wires connecting the receive in the ear tip act as antenna.
  • a tuning circuit connected between a wireless communication module and the wires is used for matching the two connected components.
  • One aspect of the present subject matter includes a receiver-in-canal (RIC) hearing assistance device for a wearer including an antenna within a device housing, an audio receiver configured to be worn in an ear canal of a wearer, and a cable assembly configured to connect the audio receiver to the device housing.
  • a circuit component such as a ferrite element (such as a bead) or an inductor, is connected to the cable assembly and configured to adjust coupling between the cable assembly and the antenna by modifying high frequency current through the wires of the cable assembly.
  • the circuit component is configured to enhance radiation from the cable assembly conductors to assist in wireless communications. In other embodiments, the circuit component is configured to limit and make more consistent the radiation from the cable assembly conductors that interfere with antenna transmissions.
  • Hearing assistance devices are only one type of hearing assistance device.
  • Other hearing assistance devices include, but are not limited to, those in this document. It is understood that their use in the description is intended to demonstrate the present subject matter, but not in a limited or exclusive or exhaustive sense.
  • Some hearing aids include an antenna for radio frequency (RF) communications.
  • Antenna performance can be affected by coupling of the antenna system with conductors of an audio receiver, which creates a flow of high frequency current through the audio receiver wires, causing the wires to become an RF radiator and causing transmission to be much different than reception for the antenna.
  • the wires will become the primary radiator with higher radiation efficiency than the intended hearing aid antenna.
  • the variance in RF gain can create wireless link performance problems. If the antenna gain is increased, the hearing aid RF receiver will be exposed to higher levels of undesirable signals that will degrade its sensitivity performance in some environments (exa examples: near a cell phone hub, tower or repeater). The hearing aid RF transmit power variation may be too high to meet regulatory requirements.
  • One aspect of the present subject matter includes a receiver-in-canal (RIC) hearing assistance device for a wearer including an antenna within a device housing, an audio receiver configured to be worn in an ear canal of a wearer, and a cable assembly configured to connect the audio receiver to the device housing.
  • a circuit component such as a ferrite element, an inductor, a capacitor, or other component, is connected to the cable assembly and configured to adjust coupling between the cable assembly and the antenna by modifying high frequency current through the wires of the cable assembly.
  • the circuit component is configured to enhance radiation from the cable assembly conductors to assist in wireless communications.
  • the circuit component is configured to limit and make more consistent the radiation from the cable assembly conductors that interfere with antenna transmissions.
  • the present subject matter improves wireless RIC hearing aids antenna performance.
  • the present subject matter improves antenna system gain consistency with different length cables and different types of receivers, and when worn by different users.
  • the present subject matter can be used to manage transmit and receive performance of the antenna system.
  • One prior solution to this problem was to use ferrites on the flex substrate that are located inside the antenna aperture.
  • locating ferrites inside the antenna aperture provides less control of the induced current. This yields poorer improvement of gain consistency and less gain control.
  • the present subject matter locates the ferrites or inductors outside the antenna aperture.
  • the present subject matter uses the audio wireless receiver, connecting cables, inductors and ferrites to adjust induced RF current flow on the receiver/cable assemblies to control hearing aid antenna system gain and make antenna performance more consistent (less uncontrolled) with different length cables and/ different types of receivers. This will also improve consistency when worn by different hearing aid wearers.
  • the present subject matter employs the use and control of induced RF current flow on the receiver/cable assemblies to control hearing aid antenna system gain.
  • the present subject matter provides series ferrites or inductors that are inserted in the receiver cable lines to reduce, control or enhance induced RF current flow on the receiver/cable assemblies to control hearing aid system gain and make antenna performance more consistent (less un-controlled) across users.
  • the ferrite or inductor is located outside of the antenna aperture. The use of inductors or properly selected ferrites reduces hearing aid system antenna gain and gain sensitivity to different length cables and different types of receivers.
  • the present subject matter can control the current distribution along the cable-receiver assembly to optimize antenna system gain consistency.
  • Various embodiments include modifying conductor impedance through modifications of geometry, materials, number of conductors and their coupling.
  • distributed coupling components are added to better match the output impedance of the receiver and transmitter ports of the radio.
  • Various embodiments can control induced RF current flow (current distribution) on the receiver/cable assemblies to control (adjust) hearing aid antenna system gain and to control (adjust) antenna system performance sensitivity to different length receiver cables, different receiver types and sizes, and different users (head size, shape and tissue density variations).
  • Various embodiments use ferrites, inductors and other distributed matching components for this function, and use varying conductive materials and geometries of those conductors to control the impedance of the receiver cable to make it a more effective radiator for RF communication.
  • RF current can be coupled to RIC cable/receiver assemblies. This affects the wireless HA antenna system gain and gain sensitivity to different length cables, different types of receivers (acoustic transducers), and human tissue proximity.
  • RF current is electromagnetically coupled to the cable assemblies due to the placement and orientation of the audio traces and cables relative to one or more radiating traces and antenna elements that are internal to the hearing aid.
  • the present systems and methods shown to control cable-receiver RF current distribution and antenna system gain apply whether the RF current is electromagnetically coupled or directly connected from the RF radio circuit to the cable-receiver assembly.
  • the antenna system gain and impedance can vary significantly for each combination of cable and receiver used.
  • portions of the radiating/receiving receiver-cable assembly are in close proximity to human tissue which can cause additional changes to the impedance, radiation efficiency and pattern directivity.
  • Differences between individual users such as head and outer-pinna size-and-shape and tissue density further contribute to antenna system gain variations. If tightly coupled to the receiver cables, greater gain variation due to receiver-cable to tissue proximity, tissue density, etc. will be seen.
  • RF current flow can be controlled by selecting one-or-more component insertion location(s) (placement), and by selection of one-or-more component RF impedance value(s).
  • a component value is selected to present desired RF impedance to current flow. Higher impedances will reduce current flow through component more than lower impedances.
  • Various embodiments can adjust location for desired electrical length (example: quarter wave). Additional embodiments can adjust location for desired balance between radiation efficiency and sensitivity to head tissue gap and density variations.
  • one location for the ferrite or inductor would be outside of the antenna aperture.
  • one or more impedances could be inserted in a location(s) that create the same (or similar) electrical lengths in the different cable assemblies at the desired operating frequencies.
  • conductor geometry and the number of conductors can be adjusted to improve induced current on the cable.
  • Distributed matching elements can be added to the cable assemblies to improve matching for the purpose of making the conductor a more effective radiator for RF communication, in various embodiments.
  • the receiver cables can be designed to be consistent and useful radiators for RF communication, in various embodiments.
  • Conductors can be shielded over some of their length to improve their matching and consistency as effective radiators, in an embodiment.
  • Matching components can be distributed over their length to improve their matching and consistency as effective radiators.

  • inserting a relatively high impedance in a cable-receiver assembly in a location a small distance from the head/tissue to reduce current flow that would be in very close proximity to human tissue reduces the tissue loading effects.
