Definitions

  • the present invention relates generally to hearing aids.
  • the invention further relates to an earpiece for a hearing aid.
  • the invention more particularly, relates to behind-the-ear hearing aids.
  • Behind-the-ear (BTE) hearing aids generally comprise a housing, a tube and an earpiece.
  • the housing accommodates electronics, a microphone and a miniature loudspeaker, which serve to pick up sounds, amplify them and produce an amplified acoustic output signal.
  • the tube provides a conduit for conveying the acoustic signal from the housing to the earpiece, and the earpiece couples acoustic energy from the tube into the ear canal.
  • the housing is placed behind the external ear, partially concealed.
  • the tube, or at least a part of it, is semi-rigid or resilient in order that the tube may also serve the purpose of resting the hearing aid on the external ear of the user.
  • the earpiece is adapted, e.g. through resilience or customization, to the users ear, to rest in the meatus of the ear canal.
  • EP-A- 1448014 provides an earpiece adapted to allow sounds from outside the ear to propagate to the tympanic membrane.
  • This earpiece comprises a resilient fiber for abutting a lower part of the concha when the earpiece is inserted in the ear canal.
  • the plug provides a comfortable, partial support for the earpiece and is adapted to direct sounds amplified by the hearing aid towards the users ear canal.
  • the support is complemented by the contact element, which rests against another part of the ear.
  • the fixture permits adjusting the contact element and thereby permits adapting the hearing aid to different sizes of ears and ear canals, or to different preferences regarding pretension.
  • the adjustment facility permits customizing the hearing aid in order that it may accommodate a wide variety of users.
  • the contact element may be partially shaped as an ellipse. It may have any other shape adapted for resting against an inside of the users tragus, thereby holding the earpiece in a fixed position when the earpiece is in use, e.g. it may be essentially circular, elliptic or triangular.
  • the contact element may be produced in different sizes for different sizes of ears.
  • the fixture comprises a number of guideways.
  • the number may be between 1 and 50.
  • the guideways may be grooves, flutes or protrusions.
  • the contact element may comprise a number of guideways adapted for interaction with the guideways on the fixture.
  • the number of guideways may be between 1 and 50.
  • the guideways may be grooves or protrusions.
  • the guideways allow the contact element to be rotated into a selected orientation relative to the earplug, thereby enabling a fitter to select the most comfortable position of resting against an inside of the user's tragus and the ear canal. Furthermore the rotational capability allows for adjusting and fixing the position of the contact element in the ear for a variety of users.
  • the fixture comprises resilient means in order to improve user comfort and to enhance the fit.
  • the earpiece is adapted for incremental adjustment.
  • the incremental adjustment permits adaptation and simple securing of the size, once decided by the fitter or the end user.
  • the adjustment may be provided by providing a flexible beam, such as a branch or a rod, with a plurality of grooves and a catch means for selectively engaging one of the grooves.
  • a flexible beam such as a branch or a rod
  • the beam may comprise a pair of opposing, generally flat faces, wherein the plurality of grooves is positioned on a first one of the faces.
  • the flat opposing faces adapt the beam for bending, e.g. into a loop.
  • the fixture may comprise catch means to retain an end of the beam.
  • the catch means comprises a rib and a resilient strand, the rib being adapted for engaging one of the grooves.
  • the beam is provided with a plurality of grooves on both of the faces. This permits looping the beam either way, e.g. for the purpose of using it for a left ear version and a right ear version, e.g. in combination with the retainer being adapted to accept the end of the beam when entered from either one of two sides.
  • the beam may be provided with a plurality of grooves on all of the faces, this provides for a better fixation of the beam.
  • the grooves may be placed with increments varying between 0.5 mm and 5 mm and preferably between 1.5 mm and 2.5 mm.
  • the earpiece comprises a body with an axis and a through axial bore, wherein the flexible beam extends from the body at an angle from the axis within a range of 45 to 90 degrees, and preferably within a range of 55 to 80 degrees from the axis.
  • the body may be generally cylindrical.
  • the retainer may simply be arranged to accept the beam end when introduced tangentially to the cylindrical body from either one of two sides, the beam being twisted due to the angled extension of the cantilevered base end.
  • the fixture is made of a material selected from the group consisting of polyamide, silicone, polyurethane, polytetrafluoroethylene, ethylvinylacetate, polyacetal, thermoplastic elastomer, polymer, elastomer, and polyoxymethylene.
  • the earpiece comprises a plug for contacting the wall of the users ear canal, in order to guide the amplified sound signal into the users auditory canal.
  • the plug is adapted to support a sound conduit tube, while it is adapted to permit exterior sounds to bypass the plug in order to reach the users inner ear.
  • This avoids uncomfortable occlusion effects.
  • the sound bypass is further a substantial advantage to users with a mild hearing deficiency, e.g. users with a hearing deficiency in only part of the frequency range, as they may then still directly hear such sounds as they are able to hear unaided.
  • the plug may be adapted to fit the ear canal, thereby not allowing external sounds to bypass the plug. This may be an advantage for moderate to high hearing loss.
  • the invention in a second aspect, provides a hearing aid according to claim 17.
  • Fig. 1 illustrates the outer ear as seen from the side

  • FIGS 2-5 show a hearing aid 12 with an earpiece 11, according to a first embodiment of the invention.
  • the hearing aid comprises a behind-the- ear housing 29 and a tube 26 transferring sound from the housing to the earpiece 11.
  • the tube 26 has a first bend 27 and a second bend 28.
  • the tube 26 is connected at one end with the housing and at the other end with the earpiece 11
  • the earpiece generally comprises a peg 15, an earplug 20 and a body 21.
  • the cross section of the body may be circular, elliptic, rectangular or any other form allowing sound from the tube to pass through to the earplug.
  • the earplug 20 allows sound from the surroundings to pass through to the tympanic membrane by one, two or more apertures 31.
  • the body 21, a rim 22, and a number of spokes 23 define the apertures.
  • the peg engages the earplug 20 by threading into a through bore of the plug, the peg having a bead 19 for securing the position.
  • Figure 5 shows a branch 13 connected with the peg 15, in a first state.
  • the branch comprises a beam-like structure protruding generally radially from the peg.
  • the branch is flexible in order that it may be formed into a loop, an exterior side of the loop providing support against the users ear when the earpiece is fitted into the ear.
