<p>In a earwax trap for use with hearing-aid apparatus and of the kind comprising a) in a first part (6) a space (8) adapted to communicate acoustically an interior part (not shown) of said hearing-aid apparatus (not shown) with the external auditory meatus (not shown) of the user's ear, and b) means (7) to prevent earwax having entered said space (8) from leaving same towards said interior part (3), the novel feature is that said leaving-preventing means comprise at least one piston- or plug-shaped member (7), which is adapted by relative movement between itself and the first part (6) containing said space (8) to enter said space (8) in a first direction away from said interior part of said hearing-aid appartus, and to leave said space (8) in the opposite direction and thus re-establish the acoustic connection between said interior part and said space (8). In this manner, earwax (15) having collected in the space (8) communicating with the user's external auditory meatus (not shown), can be expelled without using external means, such as pipe cleaners or the like, and without risk of damage to the internal parts of the hearing-aid (not shown).</p> |
