Abstract

A hearing apparatus has a housing, a receiver in the housing, and a sound conductor through which sound from the receiver is conducted out of the housing. In order to render the device as small as possible, the hearing apparatus has a cover piece which is inserted into the housing in such a way that a sound channel is formed. The sound channel is thereby delimited at the sides by the housing and the cover piece. A special sound-conducting tube can therefore be dispensed with.
