Definitions

  • the present disclosure relates to the field of hearing aids having antennas, especially adapted for wireless communication, such as for wireless communication with accessory and/or other hearing aids.
  • Hearing aids are very small and delicate devices and comprise many electronic and metallic components contained in a housing small enough to fit in the ear canal of a human or behind the outer ear.
  • the many electronic and metallic components in combination with the small size of the hearing aid housing impose high design constraints on radio frequency antennas to be used in hearing aids with wireless communication capabilities.
  • the antenna in the hearing aid has to be designed to achieve a satisfactory ear-to-ear performance despite the limitation and other high design constraints imposed by the size of the hearing aid.
  • the hearing aid comprises a hearing aid assembly having a first side and a second side, a signal processor, and a wireless communications unit.
  • the wireless communications unit is connected to the signal processor.
  • the hearing aid comprises an antenna for emission and reception of an electromagnetic field.
  • the antenna is connected to the wireless communications unit and the antenna has an excitation point.
  • a first branch of the antenna extends from the excitation point and a second branch of the antenna extends from the excitation point. At least a part of the second branch extends from the first side to the second side.
  • the second branch has at least one ground connection.
  • the antenna is configured so that current flowing in the antenna forms standing waves along the length of the antenna.
  • the length of an antenna may for example be tailored so that the length of the antenna equals a quarter wavelength of the desired electromagnetic field, or any multiple, or any odd multiple, thereof.
  • an absolute relative difference between the total length of the antenna and the wavelength may be less than a threshold, such as less than 10%, 25%, etc.
  • a total length of the antenna is between three quarters of a wavelength and five quarters of a wavelength.
  • a current in the antenna may have a maximum in the second branch, such as for example in the part of the second branch which extends from the first side to the second side.
  • the first end may be free, so that the first end may be a free end or an open end. If the first end is free, the current at the end of the first branch may be near zero. Alternatively, the first end may be interconnected with the excitation point via a third branch. The third branch may be different from the first branch. The current in the third branch may have a local maximum near the excitation point, such as a further local maximum. In some embodiments, the third branch extends along the first side of the hearing aid assembly.

  • the first and/or second branch may form a loop.
  • the loop formed by the first and/or the second branch may return to the excitation point.
  • An advantage of a loop formed by the first and/or the second branch is that it may provide a relatively long total length of the antenna and therefore may improve the ear-to-ear performance of the hearing aid.
  • the first and/or second branch may be a plate or a dish of conductive material.
  • the first antenna branch may form a loop along the first side and/or the second antenna branch may form a loop along the second side.
  • At least a part of the second branch extends from the first side to the second side.
  • the part of the second antenna branch may thus extend from proximate the first side of the hearing aid assembly to proximate the second side of the hearing aid assembly, such as from adjacent the first side to adjacent the second side, or the at least part of the second branch may extend from a point or position at or along the first side to a point or position at or along the second side.
  • At least another part of the second branch extends on the second side.
  • At least a part of the first branch may extend along the first side, and/or at least a part of the second branch may extend along the second side.
  • the first side may be a longitudinal side of the hearing aid assembly and the second side may be another longitudinal side of the hearing aid assembly.
  • the first side may be opposite the second side.
  • the second branch may be partly parallel to the first branch.

Preferably, the antenna is accommodated within the hearing aid housing, preferably so that the antenna is positioned inside the hearing aid housing without protruding out of the housing.
  • an excitation point is electrically connected to a source, such as the wireless communication unit, such as a radio chip, such as a transceiver, a receiver, a transmitter, etc.

  • the midpoint will be a midpoint at an outer side of the hearing aid assembly for the antenna to extend from the first side to the second side via the midpoint.
  • the midpoint of the hearing aid may be positioned at a partition plane for the hearing aid, so that the partition plane defines a partitioning of the hearing aid in a first part and a second part.
  • the partition plane may partition the hearing aid in two equal parts, and may e.g. define a middle of the hearing aid.
  • a distance from the midpoint to the excitation point and a distance from the midpoint to the ground connection may be of equal size.
  • the relative difference between the distance from the midpoint to the excitation point and the distance from the midpoint to the ground connection may be less than a threshold T2.
  • the threshold T2 may be e.g. 25%, or 10%.

  • the first length and/or the second length may be at least ⁇ /4.
  • the antenna may be a monopole antenna.
  • the hearing aid disclosed herein may be configured for operation in ISM frequency band.
  • the antennas are configured for operation at a frequency of at least 1 GHz, such as at a frequency between 1.5 GHz and 3 GHz such as at a frequency of 2.4 GHz.
  • an antenna refers to an electrical device which converts electric power into radio waves.
  • An antenna such as an electric antenna, may comprise an electrically conductive material connected to e.g. a wireless communications unit, such as a radio chip, a receiver or a transmitter.
  • Fig. 1 shows a block-diagram of a hearing aid.
  • the hearing aid 10 comprises a microphone 11 for receiving incoming sound and converting it into an audio signal, i.e. a first audio signal.
  • the first audio signal is provided to a signal processor 12 for processing the first audio signal into a second audio signal compensating a hearing loss of a user of the hearing aid.
  • a receiver is connected to an output of the signal processor 12 for converting the second audio signal into an output sound signal, e.g. a signal modified to compensate for a users hearing impairment, and provides the output sound to a speaker 13.
  • the hearing instrument signal processor 12 may comprise elements such as amplifiers, compressors and noise reduction systems etc.
  • the hearing aid may further have a feedback loop for optimizing the output signal.
  • the hearing aid has a wireless communication unit 14 (e.g. a transceiver) for wireless communication interconnected with an antenna 15 for emission and reception of an electromagnetic field.
  • the wireless communication unit 14 may connect to the hearing aid signal processor 12 and an antenna 15, for communicating with external devices, or with another hearing aid, located at another ear, in a binaural hearing aid system.
  • the obstacle is a head with a hearing aid comprising an antenna located closed to the surface of the head. If the wavelength is too long such as a frequency of 1 GHz and down to lower frequencies greater parts of the head will be located in the near field region. This results in a different diffraction making it more difficult for the electromagnetic field to travel around the head. If on the other hand the wavelength is too short, the head will appear as being too large an obstacle which also makes it difficult for electromagnetic waves to travel around the head. An optimum between long and short wavelengths is therefore preferred. In general the ear to ear communication is to be done in the band for industry, science and medical with a desired frequency centred around 2.4 GHz.
