## Abstract

A damping device for the anti-vibration mounting of a receiver within a hearing instrument includes an elastic damping element, a cage connected to the elastic damping element, and a shell surrounding the cage. The elastic damping element and at least a part of the shell have a lower hardness than the cage. A hearing instrument having a corresponding damping device is also provided.

## Claims

### Claim 1

A damping assembly for a hearing instrument, the damping assembly comprising:
a receiver;
a damping device for anti-vibration mounting of said receiver within said damping device, said damping device including:
an elastic damping element;
a cage connected to said elastic damping element; and
a shell surrounding said cage;
said elastic damping element and at least a part of said shell having a lower hardness than said cage.

### Claim 2 (depends on 1)

The damping assembly according to claim 1, wherein said damping element is formed of an elastomer material with a Shore hardness in a range between 20 and 30.

### Claim 3 (depends on 1)

The damping assembly according to claim 1, wherein said shell is at least partially formed of an elastomer material with a Shore hardness in a range between 50 and 60.

### Claim 4 (depends on 1)

The damping assembly according to claim 1, wherein said cage is formed of a dimensionally stable plastic or a metallic material.

### Claim 5 (depends on 1)

The damping assembly according to claim 1, wherein said elastic damping element is disposed on an inner periphery of said cage.

### Claim 6 (depends on 1)

The damping assembly according to claim 1, wherein said shell is formed as a casing enclosing said damping element in an airtight manner.

### Claim 7 (depends on 1)

A hearing instrument, comprising:
a housing;
and
a damping assembly according to claim 1 mounting said receiver within said housing in an anti-vibration manner.

### Claim 8 (depends on 7)

The hearing instrument according to claim 7, wherein said housing has a wall, and said shell of said damping device is at least partly in contact with said wall.

### Claim 9 (depends on 1)

The damping assembly according to claim 1, wherein said receiver has an outer surface disposed within said damping device.

### Claim 10 (depends on 1)

The damping assembly according to claim 1, wherein said receiver has a housing disposed within said damping device.
