Abstract

The present invention relates to a dome ( 10 ) for use with a receiver assembly ( 20 ). The dome ( 10 ) comprises a core ( 12 ) and a shell ( 14 ), wherein the core ( 12 ) and the shell ( 14 ) are made of different materials, the material of the core ( 12 ) is rigid and the material of the shell ( 14 ) is soft, and wherein the dome ( 10 ) is connectable to the receiver assembly ( 20 ) by means of a threaded connection ( 34 ). Therefore, connecting and separating the dome ( 10 ) to and from the receiver assembly ( 20 ) can be simplified in a secure and easy operation performed by the user.

First claim

The invention claimed is:

1. A dome for use with a receiver assembly, the dome comprising:
a core and a shell,
wherein the core and the shell are made of different materials, the material of the core is rigid and the material of the shell is soft,
wherein the dome is connectable to the receiver assembly by means of a threaded connection,
wherein a front face of the core comprises an indentation and a front face of the receiver assembly comprises a projection, and
wherein the indentation and the projection are configured to be engaged to each other, and
wherein the indentation and the projection are tapered and configured to provide an audible feedback signal when properly engaged.

2. The dome according to claim 1 , wherein the indentation and the projection are configured to be connected to each other when the core is completely screwed onto the receiver assembly.

3. The dome according to claim 1 , wherein the indentation and projection are located on the front face of the core and receiver assembly, respectively.

4. The dome according to claim 1 , wherein the threaded connection comprises a female thread formed into the core such to extend substantially along the longitudinal direction thereof, wherein the female thread is connectable to a male thread protruding from the receiver assembly.

5. The dome according to claim 1 , wherein the threaded connection comprises a male thread protruding from the core, wherein the male thread is connectable to a female thread formed into the receiver assembly.

6. The dome according to claim 1 , wherein the core comprises a cerumen filter adapted to protect the receiver assembly against entrance of cerumen.

7. The dome according to claim 6 , wherein the cerumen filter is opened to a passage formed into the shell.

8. The dome according to claim 7 , wherein the passage is configured to be open to an ear canal of the user of the hearing device when inserted.

9. The dome according to claim 1 , wherein the core is mounted to the shell by means of a form fit connection.

10. The dome according to claim 1 , wherein the core and shell are glued together.

11. The dome according to claim 7 , wherein the core and shell are manufactured by means of a 2-K manufacturing.

12. The dome according to claim 1 , wherein the shell is provided with a plurality of openings arranged are a circumference.

13. The dome according to claim 12 , wherein the openings configured to enable a snug fit connection of the shell inside the ear canal of the user and/or for venting.
