Patent ID: 7016512

Claim:
An at least partially in-the-canal module for a hearing aid comprising: a speaker module that generates audio signals from an electrical driving signal, said speaker module having a tubular structure with a diameter that is smaller than the canal, said speaker module including an arcuate raised ridge; and a cushion tip of elastic deformable material, said cushion tip including a tubular body enclosing said speaker module that applies an elastic force to said arcuate raised ridge to prevent removal of said speaker module from said cushion tip, said tubular body being longer than said speaker module to cause said cushion tip to deflect during navigation through the canal, and wherein a tip portion of said cushion tip possesses sufficient structural rigidity to prevent said speaker module from being pushed through said cushion tip during navigation through the canal, wherein during deflection said tip portion assumes an offset angle relative to said tubular body and said speaker module.
