  • the impact absorbing layer 112 can be a foam layer.
  • the hearing aid 100 can include a housing 114 surrounding the receiver 102, the suspension layer 110, and the impact absorbing layer 112.
  • the housing 114 can form an outer surface of the hearing aid 100, thereby defining its shape.
  • the foam layer comprises a plurality of foam pads, each of the plurality of foam pads covering a side of the receiver 102.
  • the foam layer can be an open cell foam.
  • the foam layer can be urethane.
  • the suspension layer 110 at least partially covers a first portion of the outer surface 108
  • the impact absorbing layer 112 at least partially covers a second portion of the outer surface 108, the first portion and the second portion being different.
  • the impact absorbing layer 112 covers a larger portion of the outer surface 108 than the suspension layer 110.
  • the suspension layer 110 can abut the impact absorbing layer 112. Further, as shown, the impact absorbing layer 112 can abut the housing 114. Moreover, the impact absorbing layer 112 and the suspension layer 110 are in contact with the outer surface 108 of the receiver 102.
  • FIG. 2 shows an example embodiment of a hearing aid according to the disclosure.
  • the impact absorbing layer 112 covers an outer circumference of the outer surface 108.
  • the impact absorbing layer 112 is a foam layer, and the foam layer can be a single foam pad.
  • FIGS. 3A-3B show example embodiments of a hearing aid according to the disclosure.
  • the hearing aids shown in FIGS. 3A-3B can include some or all of the features discussed with respect to FIGS. 1-2 .
  • the suspension layer 110 is separated from the impact absorbing layer 112 by a gap 302 (e.g., the layers are spaced apart).
  • the impact absorbing layer 112 can be separated from the housing 114 by a gap 304. This can allow some flexibility in the movement of the receiver 102 during wearing and/or operation.
  • FIG. 4 shows an example embodiment of a hearing aid according to the disclosure.
  • the hearing 100 includes the housing 114 discussed herein.
  • the hearing 100 is configured to be worn behind the user's ears and comprises a behind-the-ear part 402 and an in-the-ear part 404.
