Abstract

A hearing aid comprising a receiver assembly is disclosed. The receiver assembly includes a receiver and suspension member arranged in a housing. The suspension member comprises vibration dampers protruding from an outer periphery of the suspension member, and one or more cushions or one or more enclosed structures containing a material are provided between the receiver and the suspension member.

First claim

The invention claimed is:

1. A hearing aid comprising:
a receiver assembly comprising a receiver and a suspension member arranged in a housing, the suspension member comprising vibration dampers protruding from an outer periphery of the suspension member and a plurality of spacers provided at an inner periphery of the suspension member; and
one or more cushions or one or more enclosed structures containing a material provided between the receiver and the suspension member,
wherein the plurality of spacers are positioned to arrange and fix the one or more cushions or enclosed structures in predefined grooves formed by adjacent spacers in the space and between the receiver and the suspension member.

2. A hearing aid according to claim 1 , wherein the plurality of spacers provided at the inner periphery of the suspension member are configured to maintain or regain, when deformed, the shape of the one or more cushions or enclosed structures.

3. A hearing aid according to claim 1 , wherein the plurality of spacers are integrated parts or detachably fixed parts of the suspension member.

4. A hearing aid according to claim 1 , wherein the plurality of spacers comprise a resilient material, the plurality of spacers being configured to absorb shock.

5. A hearing aid according to claim 1 , wherein the suspension member comprises one or more vents.

6. A hearing aid according to claim 1 , wherein the suspension member comprises one or more sealing members configured to control air flowing into and out of the one or more cushions or enclosed structures.

7. A hearing aid according to claim 1 , wherein the one or more cushions or one or more enclosed structures are integrated in or detachably fixed at the inside structure of the suspension member.

8. A hearing aid according to claim 1 , wherein the one or more cushions or one or more enclosed structures have a geometry that fits the outer geometry of the receiver such that the receiver fits within the cavity formed by the suspension member and the one or more cushions or enclosed structures.

9. A hearing aid according to claim 1 , wherein each of the one or more cushions or enclosed structures is formed by one or more continuous structures containing air or another filler material or a series of continuous sub-structures forming a cushion.

10. A hearing aid according to claim 1 , wherein at least one of the one or more cushions or enclosed structures are positioned between a spacer and a vent and/or positioned between a spacer and a sound port exit.

11. A hearing aid according to claim 1 , wherein the housing comprises detachably connected receiver housing components adapted to define the housing in an attached configuration and adapted to accommodate receivers of different geometry and/or size and/or mechanical dimensions.

12. A hearing aid according to claim 1 , wherein the receiver housing comprises a front portion and a rear portion, wherein the front portion and the rear portion comprises attachment structures for detachable attachment of the front portion to the rear portion.

13. A hearing aid according to claim 1 , wherein a sound tube protrudes from the suspension member, wherein the receiver assembly comprises a casing tube inserted into the sound tube or encasing the sound tube, wherein the casing tube is made in a material that is harder than the sound tube.

14. A hearing aid according to claim 1 , wherein a sound hook is attached to a sound tube, wherein an acoustic damper element is arranged in the sound hook.

15. A system comprising a hearing aid according to claim 1 , wherein the system comprises an insertion tool having a flexible rod member configured to receive an acoustic damper element, wherein the insertion tool is adapted to position the acoustic damper element in a predefined position in a sound hook.
