发明名称 Earwax filter and handing tool for such filter
摘要 <p>The invention concerns a transducer protection comprising a top cap, a stem extending from the top cap and having a distal end and a seal at the stem distal ends. The top cap has an outward facing and an inward facing side, the inward facing side facing the hearing aid, when in use. The stem protrudes into an opening of a hearing aid component to be protected, when in use. The stem's proximal end is connected to the top cap at the top caps inward facing side. The protection has an outward facing contour that is adapted to match an inner wall of the hearing aid component's opening so that the outer contour of the seal contacts the inner wall of the opening, when in use. Within the seal, at least one sound opening is provided that is surrounded by the seal. The sound opening surrounded by the seal communicates with at least one sound opening along the stem. On the inward facing side of the top cap at least one spacer is provided, that is formed to provide for a gap between the inward facing side of the top cap and an outer surface of a hearing aid component, when in use. The gap that is caused by the spacer acts as sound entrance between the top cap and the hearing aid component's outer surface.</p>
