Abstract:
A hearing aid component with earwax filter is provided, wherein the hearing aid component has a sound inlet opening that has at least two sound inlet portions having different diameters and being displaced with respect to each other in a longitudinal direction of the sound inlet opening so that the sound inlet opening narrows towards the interior of the hearing aid component so that more proximal sound inlet portion has a relatively larger diameter and more distal sound inlet portion has a relatively smaller diameter. The earwax filter is placed in said sound inlet opening and comprises: a cap with an outward-facing and an inward-facing side, and a peripheral edge, said peripheral edge being force-fitted into the sound inlet portion with the relatively larger diameter. The cap has a plurality of sound inlets arranged along the periphery of the cap wherein the sound inlets are arranged along a perimeter of the cap.
