Abstract
The disclosure is directed to an elongated and tapered, bulb-like hollow housing which is constructed and arranged to fit in the outer ear of the wearer having a plurality of openings formed therein circumferentially disposed to define rib portions which are substantially parallel to the longitudinal axis of the housing. The tapered end has a small opening formed therein which by comparison is substantially smaller in diameter than that of the bulb-like hollow housing. A flexible conduit which has one end adapted to fit a sound transmitting device, such as a hearing aid or other acoustical device has the other end extending through the hollow housing into the small opening in an acoustic coupling relationship. An end cap in the form of a disc may be secured in the larger open end of the tapered cylindrical housing to receive the flexible conduit and may also be formed with a number of apertures therein. Two discs may also be used to control the size of the openings by using a side-by-side arrangement.
