Abstract (en)
[origin: EP1653776A2] The hearing device (1) comprises an insertable part (16), which is to be inserted into an ear canal of a user of the hearing device (1). The insertable part (16) may be identical with the hearing device (1) itself, and the insertable part (16) comprises a casing, which casing comprises a deformable part (2). The hearing device (1) comprises means for changing a cross-sectional area (20) of the deformable part (2), which change in the cross-sectional area (20) is reversible. The means for changing a cross-sectional area (20) of the deformable part (2) may comprise at least one deformable volume (5) containing a fixed amount of a filler (4). The means can be a means for changing the cross-sectional area (20) of the deformable part (2) through changing the axial extension of the deformable part (2). The means can be a volume capacity change means for changing the cross-sectional area (20) of the deformable part (2) through changing the capacity of a variable volume arranged within the hearing device (1), the deformable part (2) being arranged on the outside of the variable volume.
