摘要:
A hearing aid (1) comprises a receiver (19), an output port (6), a conduit (13) for conveying sound to the port and a barrier element (39) adapted for baffling entry of ear wax and moisture and for being acoustically transparent. The invention further provides a barrier element (39) for a hearing aid comprising a slab having an exterior surface and through openings for transverse transmission of sound, wherein the exterior surface is super-hydrophobic.
摘要:
An earplug (100) for a hearing aid including an ear canal body part (103) with a bore (106) and a sound output passage (107) in communication with the bore and leading to a sound output opening (105) and flanges (104a-d) surrounding said ear canal body part and being adapted to engage a wall of an ear canal, wherein said flanges are substantially disc shaped and have an axis of symmetry that is substantially parallel to the axis of symmetry of the bore of the ear canal body part. The invention further provides a hearing aid and a method of inserting a probe tube in an earplug.
摘要:
A method for coating of a hearing aid said method comprising the deposition of an adhesion layer that does not develop corrosive reaction products. The method comprises applying an organometallic compound to the surface of the hearing aid component using vapour phase deposition, inducing a reaction to convert it to a metal oxide, then applying a silane molecule to the surface, and inducing a reaction between the applied silane molecule and the metal oxide. The invention also relates to a hearing aid comprising a component for a hearing aid provided with a hydrophobic coating comprising a layer of aluminium oxide, and a coating for a hearing aid component. The coating is produced in a system (701) for vapour phase deposition of precursors.

A hearing aid earpiece (1) is provided, that is custom fitted to the individual shape of the ear canal of a user and manufactured in a rapid prototyping process. The earpiece comprises a sound conduit (3) that is adapted for conveying an acoustic signal from an acoustic inlet port towards an acoustic outlet port and wherein the sound conduit is looped such that at least one geometrical plane, will intersect the sound conduit at least three times thereby providing a length of the sound conduit exceeding a largest outer dimension of the hearing aid earpiece. The invention also relates to a hearing aid comprising such a hearing aid earpiece and a method for manufacturing such an earpiece.
