Abstract
A hearing instrument is adapted for positioning in the external auditory canal of a human proximal to the tympanic membrane. It includes a substantially rigid shell and a relatively flexible tip member. The tip member includes a hollow body portion defining a elongated passage for the communication of acoustic signals through the tip member. The hollow body portion of the tip member is sufficiently deformable so that an axis of the passage substantially conforms to an axis of the external auditory canal upon insertion. The hollow body is also significantly rigid to resist substantial collapse of the passage upon such insertion. The axis of the passage defined by the hollow body portion is moveable at an angle with respect to the axis of the shell so that the hearing instrument can navigate the canal during insertion. Wax guard and receiver mounting configurations as well as a method of assembly are also described.
