Abstract
Abstract The housing of the hearing aid comprises a distal, bead-like head part having a planar face on which an arched face plate is seated and comprises a proximal, thinner tail part. The angle α between the normal of the planar face and the longitudinal axis of the tail part lies in the range of 135° through 142°, preferably at 140°, in a first longitudinal plane through the housing and a corresponding angle β in a second, perpendicular longitudinal plane through the housing lies in the range from 12° through 17°, preferably at 14°.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
102 words
An in-the-ear hearing aid, including a pear-shaped housing that encompasses a distal, bead-like head part having a planar face on which a face plate is seated and encompasses a proximal, thinner tail part, whereby a longitudinal axis of the tail part is angled off relative to a normal line of the planar face of the head part in two mutually perpendicular longitudinal sectional planes of the housing, comprising the improvement wherein an angle α between the normal line of the planar face and the longitudinal axis of the tail part lies in the range of 135°-142° in one of said longitudinal planes.
Claim 2
Dependent Claim
