## Abstract

A component for a vehicle, includes at least one component part, which is made of a magnetically active foam material and/or a foam material which can be magnetically activated and/or a dielectric elastomer. The component is at least partially or completely laterally delimited so that the component elastically expandable in at least one degree of freedom. The component can be a switch element, a transducer, an active muffler, and/or an energy conversion element.

## Claims

### Claim 1

A component for a vehicle, comprising:
at least one component part, which is formed from a magnetically active and/or magnetically activatable foam material and/or a dielectric elastomer, the component part being laterally delimited at least partially or completely in such a way that the component part is elastically expandable with at least one degree of freedom.

### Claim 2 (depends on 1)

The component as claimed in claim 1, wherein the component part is delimited by a frame.

### Claim 3 (depends on 1)

The component as claimed in claim 1, wherein the component part is delimited by at least one adjacent further component.

### Claim 4 (depends on 3)

The component as claimed in claim 3, wherein at least one adjacent further component lies against the component part with positive and non-positive engagement.

### Claim 5 (depends on 1)

The component as claimed in claim 1, wherein the component part is delimited by being arranged in a wall of an opening.

### Claim 6 (depends on 1)

The component as claimed in claim 1, wherein the component part is delimited by being encapsulated in a further material, the further material having a corresponding strength.

### Claim 7 (depends on 1)

The component as claimed in claim 1, wherein the component is at least one of a switching element, a sound transducer, an active sound damping element, and an energy conversion element.
