## Abstract

There is provided a microphone comprising a microphone capsule and a microphone capsule suspension. The microphone capsule suspension has a first and a second housing portion and a decoupling unit. In that case the microphone capsule is mounted to the decoupling unit for solid-borne sound decoupling. The decoupling unit is in turn fixed to the first and/or second housing portion. The decoupling unit has a shape-changing portion which under loading changes its shape. The decoupling unit has at least two arms which each have a first and a second end. The second ends of the arms respectively have a fixing portion for receiving a microphone capsule. Each arm has a shape-changing portion which changes its shape under a first loading and an elastic portion which permits elastic deformation in respect of length as from a second loading.

## Claims

### Claim 1

A microphone comprising:
a microphone capsule; and
a microphone capsule suspension;
wherein the microphone capsule suspension comprises:
a first and a second housing portion; and
at least one decoupling unit;
wherein the microphone capsule is mounted to the decoupling unit for solid-borne sound decoupling;
wherein the decoupling unit has comprises:
at least one shape-changing portion which changes its shape under loading; and
at least two arms which each have a first and a second end;
wherein the second ends of the arms are connected to a fixing portion which receives the microphone capsule; and
wherein each arm has:
a shape-changing portion which changes its shape under a first loading; and
an elastic portion which elastic deforms in a length direction under a second loading.

### Claim 2 (depends on 1)

The microphone as set forth in claim 1;
wherein the microphone capsule suspension has two decoupling units; and
wherein the microphone capsule is mounted with a first end of the microphone capsule in one decoupling unit, and a second end of the microphone capsule in the other decoupling unit.

### Claim 3 (depends on 1)

The microphone as set forth in claim 1;
wherein the decoupling unit is made from one material.

### Claim 4 (depends on 1)

The microphone as set forth in claim 1;
wherein the shape-changing portions have a configuration which is round, annular, oval, or rectangular, or have a configuration with at least one hole in the center.

### Claim 5 (depends on 2)

The microphone as set forth in claim 2;
wherein the decoupling unit is made from one material.

### Claim 6 (depends on 2)

The microphone as set forth in claim 2;
wherein the shape-changing portions have a configuration which is round, annular, oval, or rectangular, or have a configuration with at least one hole in the center.

### Claim 7 (depends on 3)

The microphone as set forth in claim 3;
wherein the shape-changing portions have a configuration which is round, annular, oval, or rectangular, or have a configuration with at least one hole in the center.

### Claim 8 (depends on 5)

The microphone as set forth in claim 5;
wherein the shape-changing portions have a configuration which is round, annular, oval, or rectangular, or have a configuration with at least one hole in the center.
