Open the CIPO recordAbstract From the Canadian patent
The hearing aid has a flexible printed circuit film having a printed circuit wing bent around a rounded portion and, also has a hearing coil. In order to save space the hearing, coil is preferably divided into two smaller series-connected, coil windings. These can be symmetrically arranged in the hearing aid housing. Since the bending coinciding with the rounded portion is not suitable for the contacting of components the hearing coil is radially arranged thereabove in a protective member. An even more space-saving arrangement of the components in the hearing aid housing thus results.
