16. The hearing aid as claimed in claim 15, wherein the membrane included in the frame comprises polytetrafluoroethylene.
FIG. 1 shows two different embodiments of the third housing part 3 a and 3 b. The housing part 3 a itself contains no active components here. The acoustic stimulus is generated by the electronic components in the housing part 2 and conducted by the housing part 3 a into the auditory canal of the user. In order to configure the hearing aid so that it is as water-tight as possible for active users and to protect the electronic components from damage in the process, there is a water-tight membrane 16 at the tip 6 of the housing part 3 a. This prevents the ingress at least of liquid water into the housing part 3 a. In return the membrane allows sound at least to exit from the housing part 3 a. The membrane 16 also preferably allows water vapor to exit from the housing part 3 a.
The housing part 3 b that can be used as an alternative has a sound converter 17 at its end away from the second housing part. So that this is not damaged by moisture, like the electronic components in housing part 2 and 1, there is also a sound-permeable but water-tight membrane 16 at the opening of the housing part 3 b. The sound converter 17 is connected by way of connecting lines within the housing part 3 b to the electronic component in the housing part 2. Since the generated sound is not impaired by resonances in the housing part 3 a, a better sound quality results when housing part 3 b is used.
