Hearing aid with an electrodynamic acoustic transducer
First Claim
1. In a hearing aid having an electrodynamic transducer, the improvement comprising:
- a housing,an ear tube, said ear tube having an interior portion for allowing sound waves generated by the electrodynamic acoustic transducer to be transmitted therethrough and being movably supported relative to said housing,said ear tube having a distal opening adapted for communicating with an auditory canal the distal opening having a first axis substantially perpendicular to a plane defined by the distal opening and said electrodynamic transducer having an axis of rotation relative to said housing, said ear tube being positioned so that said first axis intersects said axis of rotation at a predetermined angle and at a location proximal to the distal opening; and
a loudness regulator, said loudness regulator comprising a base and a flap, said base providing a recess adapted to receive a battery for electrical connection and said flap being moveable relative to said base between open and locked states.

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.
