 in der Kapsel 2 und von dieser auf das Röhrchen 19, so dass dadurch die durch den Schall hervorgerufenen Schwingungen der Membran 16 entsprechend verstärkt zu dem Trommelfell gelangen. Die Luftblase 21 in der Kapsel 2 bildet wieder einen Spannungsregler für die Flüssigkeit in der Kapsel 2. 



   Wird in das Gummiröhrchen   19   der Kapsel 2, wie bei der Ausführung nach Fig. 2 und 3, eine Drahtspirale 3 eingezogen, so wird durch die durch die Drahtspirale in der Wandung des Röhrchens hervorgerufene Wellung 6 eine grosse Abgabefläche erzielt, durch welche ein Teil der Schallenergie durch die erregte Flüssigkeitsmenge der Gehörgangsluft abgegeben wird, so dass die Luft im Gehörgang wieder in dem gleichen Sinne erregt wird, wie das Trommelfell durch die Spitze der Membran 7. 



   PATENT-ANSPRÜCHE :
1. Vorrichtung zur Erleichterung des Hörens für Schwerhörige, bei welcher eine in der Ohr-   muschel   angebrachte Lautaufnahmemembran mit einem an dem Trommelfell anliegenden Membran-   säckchen   in Verbindung gebracht ist, dadurch gekennzeichnet, dass die Verbindung zwischen der Laut-   aufnahmemembran     (1)   und dem   Membransäckchen     (5   bzw. 7) durch eine Spiralfeder bzw. ein Flüssigkeitsmedium erfolgt.

 in the capsule 2 and from this onto the tube 19, so that the vibrations of the membrane 16 caused by the sound thereby reach the eardrum in a correspondingly stronger manner. The air bubble 21 in the capsule 2 again forms a voltage regulator for the liquid in the capsule 2.



   If a wire spiral 3 is drawn into the rubber tube 19 of the capsule 2, as in the embodiment according to FIGS. 2 and 3, the corrugation 6 caused by the wire spiral in the wall of the tube creates a large dispensing area through which a part of the Sound energy is emitted by the excited amount of fluid in the auditory canal air, so that the air in the auditory canal is again excited in the same sense as the eardrum is excited through the tip of the membrane 7.



   PATENT CLAIMS:
1. A device to facilitate hearing for the hard of hearing, in which a sound recording membrane mounted in the auricle is connected to a membrane sac resting on the eardrum, characterized in that the connection between the sound recording membrane (1) and the Membrane bag (5 or 7) takes place by a spiral spring or a liquid medium.

Claims

2. Hearing device according to claim 1, characterized in that a spirally wound wire (3) is attached to the sound recording membrane (1) mounted in the auricle, the other end of which carries the membrane bag (5).

3. Hearing device according to claim 2, characterized in that the free end (4) of the spiral spring (3) is designed as a loop onto which the membrane bag (5) is pushed.

4. Hearing device according to claim 2, characterized in that a tube (6) made of soft rubber is pushed onto the spiral spring (3).

5. Hearing device according to claim 4, characterized in that the tube (6) with the membrane bag (7) consists of one piece.

6. Hearing device according to claim 5, characterized in that the capsule (2) and the tube (6) are filled with a liquid through which the sound waves are transmitted from the sound recording membrane (1) to the membrane bag (7).

7. Hearing device according to claim 6, characterized in that the capsule (2) is divided into two or more liquid chambers (2 and 9) which are closed to the outside and from one another by membranes (16, 13 and 10) of different sizes, through which the liquid mass is separated and which enable an amplification of the oscillations of the membranes according to the principle of the hydraulic press.

8. Hearing device according to claim 7, characterized by the fact that one air bubble (20, 21) is left in the liquid of the individual liquid chambers (2 and 9), which prevents the chambers from shattering in the event of sudden strong pressure fluctuations.

9. Hearing device according to claim 7, characterized in that the receiving membrane (16) is firmly clamped with its edge in a ring (15) and against a pin j! the membrane (. is pressed in so that the center of the receiving membrane (16) has a conical shape.

10. Hörvon'ichtung according to claims 1 to 8, characterized in that the connecting tube (6 or 19) has a smaller diameter than the inside diameter of the auditory canal, so that between the tube and the walls of the auditory canal There remains a space in which the air in the ear canal is set into vibrations and thus also on the Eardrum can act.
