Abstract
The invention is directed to a hearing aid with an electrodynamic acoustic transducer. Such hearing aids were previously produced by otoplastic techniques. A novel acoustic transducer which departs from the construction principle previously employed for construction of the acoustic transducer is known from the German Application P 43 29 892.2. The object of the present invention is to provide a solution for the practical use of the edged acoustic transducer in a hearing aid and to simplify the production of a hearing aid. This object is met according to the invention by a hearing aid in which the housing of the hearing aid has a movably supported ear tube in which sound waves generated by the electrodynamic acoustic transducer can be transmitted through the interior of the ear tube. As a result of the invention, the manufacture of a hearing aid is substantially simplified and manufacturing costs are dramatically reduced.
