Definitions

  • the present disclosure relates to hearing aid, and more particularly a hearing aid for being worn in or at an ear canal of a user which may be manufactured in a simple manner ensuring control over position of the telecoil.
  • the present disclosure provides a hearing aid for being worn in or at an ear canal of a user, the hearing aid comprising:
  • An advantage of the hearing aid may be that the telecoil may be kept in a fixed relationship with respect to the housing, which ensures control of the orientation of the telecoil (such as ensures that an axis of the telecoil is in the range [30; 120] degrees with respect to horizontal during use), which may be relevant for, e.g., optimal receipt of signals transmitted to the telecoil.
  • Another advantage may be that the telecoil is kept in a fixed relationship with the housing ensures control of the orientation and/or position of the telecoil with respect to other units, such as an antenna suitable for 2.45 GHz wireless communication and/or suitable for 5.1, 5.8 GHz wireless communication, of the hearing aid, which may be relevant for improved antenna performance.
  • Control of position and/or orientation may be advantageous for overcoming potential problems related to audible artifacts, level dependent distortion and/or degradation in performance of other units, such BluetoothTM Low Energy (BLE) antenna performance degradation.
  • BLE BluetoothTM Low Energy
  • the telecoil is kept in a fixed relationship with the housing ensures control of the orientation and/or position of the telecoil with respect to other units, such as the output transducer.
  • This may be relevant since current drawn in connection with operation of the output transducer (which may also be referred to as 'reciever' or speaker unit) may generate electromagnetic radiation interfering with communication via the telecoil, but having the telecoil rigidly mounted on the rigid fixation part which in turn is rigidly mounted on the housing enables avoiding that the physical relationship between the output transducer and the telecoil changes undesirably during use. Since the spatial relationship is fixed this way, and is thus known, it may be possible to reduce the interference.
  • 'hearing aid' may be understood a device that is adapted to improve or augment the hearing capability of a user by receiving at least the transmitted output audio signal, but also the option to use or include an acoustic signal from a user's surroundings, and generating a corresponding audio signal, possibly modifying the audio signal and providing the possibly modified audio signal as an audible signal to at least one of the user's ears.
  • the "hearing aid” may alternatively or further refer to a device such as an earphone or a headset adapted to receive an audio signal electronically, possibly modifying the audio signal and providing the possibly modified audio signals as an audible signal to at least one of the user's ears.
  • Such audible signals may be provided in the form of an acoustic signal radiated into the user's outer ear, or an acoustic signal transferred as mechanical vibrations to the user's inner ears through bone structure of the user's head and/or through parts of middle ear of the user or electric signals transferred directly or indirectly to cochlear nerve and/or to auditory cortex of the user.
  • a hearing aid in general, includes i) an input unit such as a microphone for receiving an acoustic signal from a user's surroundings and providing a corresponding input audio signal, and/or ii) a receiving unit, such as a hearing aid wireless interface, for electronically receiving an input audio signal, such as the transmitted output audio signal.
  • the hearing aid may further include a signal processing unit for processing the input audio signal and an output unit, such as an output transducer, for providing an audible signal to the user in dependence on the processed audio signal.
  • the input unit may include multiple input microphones, e.g. for providing direction-dependent audio signal processing.
  • Such directional microphone system is adapted to enhance a target acoustic source among a multitude of acoustic sources in the user's environment.
  • the directional system is adapted to detect (such as adaptively detect) from which direction a particular part of the microphone signal originates. This may be achieved by using conventionally known methods.
  • the signal processing unit may include an amplifier that is adapted to apply a frequency dependent gain to the input audio signal.
  • the signal processing unit may further be adapted to provide other relevant functionality such as compression, noise reduction, etc.
  • the output unit may include an output transducer such as a loudspeaker/receiver for providing an air-borne acoustic signal transcutaneously or percutaneously to the skull bone or a vibrator for providing a structure-borne or liquid-borne acoustic signal.
  • an output transducer such as a loudspeaker/receiver for providing an air-borne acoustic signal transcutaneously or percutaneously to the skull bone or a vibrator for providing a structure-borne or liquid-borne acoustic signal.
  • hearing aids which fit in (such as exclusively in) the "bowl" (pinna) and/or the ear canal of the ear, such as in-the-ear (ITE) type hearing aids, In-the-Canal hearing aids (ITC) and/or Completely-in-the-canal hearing aids (CIC).
  • ITE in-the-ear
  • ITC In-the-Canal hearing aids
  • CIC Completely-in-the-canal hearing aids
  • the present disclosure further relates to in-the-ear (ITE) type hearing aids.
  • the hearing aid may be part of a "binaural hearing system” which refers to a system comprising two hearing aids where the hearing aids are adapted to cooperatively provide audible signals to both of the user's ears.
  • the hearing aids of the binaural hearing aid system need not be of the same type.
  • topographical feature' may be understood a structural feature differing from a planar surface.
  • a topographical feature may comprise one or more recesses and/or one or more protrusions.
  • the first topographical feature may be monolithically integrated with the housing.
  • topographical features may be that they define the position and orientation of the telecoil.
  • An advantage may thus be that the topographical features, which may in a simple manner be provided very consistently during manufacture of the housing and the fixation part, thus define the spatial relationship between the telecoil and the housing and this enables defining the spatial relationship between the telecoil and other units of the hearing aid.
  • this spatial relationship may in a simple, yet effective manner be effectively be defined with high precision and low tolerances during manufacture of the units, such as the housing and fixation part, rather than at the stage of assembly of the housing, fixation part and telecoil (and optionally other units).
  • the first topographical feature may be positioned on the interior wall of the housing, such as on the interior facing side of the face plate.
  • 'rigidly mounted is understood that the parts being rigidly mounted to each other are kept in a fixed spatial relationship, such as wherein position and/or orientation with respect to each other are kept constant, such as constant during normal use. For example, if the hearing aid is dropped on a flat, hard surface from a height of 1 meter, the position before/after the drop should not be able to differ by more than 0.1 mm, such as more than 0.01 mm.
  • 'rigid' may be understood that the corresponding part, such as the rigid fixation part, does not deform during normal use.
  • the 'fixation part' may in an alternative wording be described as a holder part for holding the telecoil and defining the telecoil's position with respect to the housing.
  • the fixation part may comprise, such as consist of, a material with a Young's modulus being equal to or larger than a Young's modulus of the housing at the position where the fixation part is mounted.
  • the fixation part may comprise, such as consist of, solid polymer.
  • the fixation part may comprise, such as consist of, a material with a Young's modulus being equal to or larger than 0.1 GPa, such as equal to or larger than 0.5 GPa, such as equal to or larger than 1.0 GPa.
  • the fixation part may comprise, such as consist of, a material with a Young's modulus being equal to or less than 2000 GPa, such as equal to or less than 200 GPa, such as equal to or less than 20 GPa.
  • 'mounted on the housing' may be understood mounted on an inside wall of the housing.
  • a hearing aid wherein the fixation part is mounted on the housing via glue.
  • the fixation part may then be glued to the housing and/or the first topographical features, such as a holder of or an existing component, such as a microphone or a near field magnetic induction coil.
  • a hearing aid wherein the telecoil is partially encircled by the rigid fixation part around an axis of the telecoil, wherein the partial encirculation spans an angular range of equal to or less than 180 degrees, such as equal to or less than 150 degrees, such as equal to or less than 120 degrees.
  • This may for example be realized by having the third topographical feature corresponding to a cylindrical, concave recess with the shape of a segment of a circle, which segment at most corresponds to a semi-circle.
  • An advantage of this may be, that during mounting, the telecoil can be placed into the third topographical feature by movement in a direction orthogonal to the axis of the telecoil (which may in turn facilitate simple mounting processes and/or reduced risk of damage to the telecoil for example because it is not necessary to move/slide the telecoil into the third topographical feature in a direction parallel with the telecoil).
  • a hearing aid wherein the third topographical feature is arranged so that the mounting, the telecoil can be placed into the third topographical feature by movement in a direction orthogonal to the axis of the telecoil.
  • the third topographical feature corresponding to a circular, cylindrical, concave recess with the shape of a segment of a circle, which segment at most corresponds to a semi-circle, such as which corresponds to the size and shape of the telecoil 110 (where 'corresponds' in this context may be understood to imply that the diameter of the segment of the circle of the third topographical features matches, such as is within ⁇ 1 0 % of the outer diameter of the telecoil).
  • a hearing aid wherein the hearing aid comprises a plurality of wireless receivers, such as wireless receivers for receiving electromagnetic signals, such as BluetoothTM (such as BluetoothTM Low Energy (BLE)) and/or near-field magnetic induction (NFMI).
  • Wireless transmission may in general be carried out using any one of a number of protocols and/or carriers, including, but not limited to, near-field magnetic induction (NFMI), baseband modulation, BluetoothTM, WiFi-based, radio frequency (RF) transmission, such as in the Giga Hz range, or any other type of suitable carrier frequency and/or using any other type of suitable protocol.

  • RF radio frequency
  • a hearing aid wherein the hearing aid comprises a BluetoothTM receiver, such as a BluetoothTM Low Energy (BLE) receiver.
  • a BluetoothTM receiver such as a BluetoothTM Low Energy (BLE) receiver.
