  • Figs. 6 and 7 are cross-sectional elevation views of a wax-resistant dome employing alternative configurations of the receiver tube retainer
  • Figs. 8 and 9 are perspective views of a wax-resistant dome with elliptical and curved vents.
  • Figs. 10 and 11 are drawings of a wax-resistant dome incorporated into the shell of a hearing instrument. Best Mode for Carrying out the Invention
  • a hearing instrument receiver tube 20 is attached to a wax-resistant dome 30 positioned in the ear canal.
  • the wax-resistant dome 30, shown again in Fig. 2 comprises a hollow dome shell 32 having a partial spherical outer surface 34.
  • the outer surface 34 may assume a variety of shapes, including a partial sphere, an ellipsoid such as a partial oblate or prolate spheroid (see the dashed line 60 in Fig. 1), or any other shape, including irregular two-dimensional surfaces, suitable for the hearing application and the user's ear canal.
  • the wax-resistant dome 30 has sound vents 70 distributed over the outer surface 34 of the dome 30.
  • the sound vents 70 allow sound exiting from the receiver tube 20 to pass into the ear canal and also equalize the air pressure on either side of the dome 30.
  • the sound vents 70 in Fig. 2 are positioned approximately midway between the top 36 and the bottom 38 of the dome 30, but may be located higher or lower on the dome 30.
  • FIG. 3 A cross-sectional view of the wax-resistant dome 30, illustrating the dome shell wall 40 and the hollow, interior volume 42, is shown in Fig. 3. Note that the receiver tube 20 is not shown as a cross section in this figure.
  • the dome shell wall 40 may be fabricated from a soft material for user comfort.
  • the receiver tube 20 is held vertically within the dome 30
  • a receiver tube retainer 100 comprising a sound-impervious horizontal member 102 and a receptacle such as a vertically-oriented sleeve 110 that releasably accepts the end 22 of the receiver tube 20.
  • the retainer 100 may be held in place within the dome 30 by any suitable method, e.g., a detent, recess, an annulus, or nubs 46 on the inside surface 48 of the dome shell wall 40 that receive the horizontal member 102.
  • a suitable glue or epoxy may also be employed.
  • the receiver tube retainer 100 is positioned below the sound vents 70 in the lower half 50 of the dome 30.
  • the retainer 100 also shown separately in the cross-sectional elevation view of Fig. 4 and the bottom view of Fig. 5, comprises an outer perimeter 104 that conforms to the dimensions of the inside surface 48 of the dome 30.
  • the outer perimeter 104 is circular, but may also be elliptical or any other suitable shape matching the corresponding shape of the inside surface 48 of the dome shell 32.
  • the top end 112 of the vertically-oriented sleeve 110 comprises a partial closure 114 having an opening 116 aligned with and adjacent to the opening 24 in the end 22 of the receiver tube 20.
  • the horizontal member 102, the sleeve 110, and the partial closure 114 of the retainer 100 are shown with a cross-hatch in
  • the dome 30 and the retainer 100 could be fabricated as a monolithic component.
  • the receiver tube 20 passes through the receiver tube 20 and exits through the opening 24 in the end 22 of the receiver tube 20. From the opening 24, the sound enters the interior volume 42 of the dome 30, and passes out of the dome 30 through the sound vents 70 and into the ear canal.
  • the sound-impervious horizontal member 102 prevents the sound from exiting the dome 30 through the open dome shell bottom 38. As shown in Fig. 5, one or more pressure equalization vents 106 may be provided in the horizontal member 102 to counter the occlusion effect if air cannot pass between the outer surface 34 of the dome 30 and the ear canal walls 10.
  • the receiver tube retainer 300 comprises a sound-impervious horizontal member 302 and a vertically-oriented tubular section 310 inserted 26 through the opening 24 at the end 22 of the receiver tube 20.
  • An alternative version of this retainer is shown in Fig. 7, which has an outer tubular section 320 encompassing the adjacent portion of the receiver tube 20.
  • a thread 330 may be provided on the inside surface 322 of the outer tubular section 320 adjacent the receiver tube 20 or on the outside surface 312 of the vertically-oriented tubular section 310.
  • the sound vents 70 shown in Figs. 1-3 have a rectangular shape and lie in a plane transverse to the vertical axis 44 of the dome 30.
  • Sound vents 170 having an elliptical shape are shown in Fig. 8 and one sound vent 270 having the shape of an "s"-curve (sound vent 270) is illustrated in Fig. 9.
  • the wax-resistant dome 30 may be attached to a receiver tube 20 extending from a hearing instrument receiver in a behind-the-ear or in-the-ear hearing instrument (neither shown). Should cerumen (wax) enter the dome 30, the dome 30 can be cleaned by clearing the sound vents 70 and the interior volume 42 of the dome shell 32.
  • the dome 30 may also be used with the shell 210 of an in-the-ear or a completely-in-the-canal hearing instrument, as illustrated by the hearing instrument 200 in Fig. 10. As opposed to a dome that spans the full width of the hearing instrument shell in Fig. 10, a smaller dome could be used, as shown in Fig. 11. There, the hearing instrument 300 has a vent 310 adjacent the dome 330.
  • the foregoing devices find industrial applicability in the field of hearing instruments.

Abstract

Pour protéger l'ouverture d'un tube récepteur contre le cérumen, on peut placer l'extrémité de ce tube dans un dôme doté d'évents qui laissent passer le son. Le dôme et les évents peuvent se présenter sous des formes diverses.
