Hearing aid component with earwax filter

摘要

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.

主权项

1. A hearing aid component with earwax filter, said hearing aid component comprising:
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; and said earwax filter placed in said sound inlet opening and including
a cap with an outward-facing and an inward-facing side, said inward-facing side facing the hearing aid, when in use, and a peripheral edge, said peripheral edge being placed into the sound inlet portion with the relatively larger diameter,a stem protruding into the sound inlet portion with the relatively smaller diameter, said stem having a proximal end connected to the cap and a distal end, and said stem having a diameter that is smaller than the diameter of the sound inlet portion with the relatively smaller diameter so as to leave an annular gap between the stem and the sound inlet portion with the relatively smaller diameter, the annular gap being immediately adjacent to said cap and said stem, wherein the cap includes a plurality of sound inlets arranged along the periphery of the cap and being shaped so as to allow ambient sound passing into the annular gap, wherein the sound inlets are arranged along a perimeter of the cap.
