摘要：The invention relates to a housing (1) for a hearing aid that can be inserted intothe pinna, comprising an auditory canal part (3). One end of said housing is provided witha cover panel (2) that has a traversing bore (7). A protective element against cerumen isdisplaceably mounted in said traversing bore (7). The protective element has an upperbow (11), in addition to two lateral props (12) and a lower intermediate strut (13), a sonictransmission chamber (14) being formed between the bow (11) and the intermediatestrut (13). The protective element against cerumen (10) permits practically unhinderedsonic transmission in a lower operational position, without admitting cerumen or
cutaneous particles into the sonic outlet (4) of the tube section (6). In the upper position,the intermediate strut (13) completely closes the traversing bore (7) in the cover panel(2), while the sonic transmission chamber remains freely accessible for cleaning using anappropriate small brush.
