1. An earphone comprising:
- a resilient member being adapted to at least partly be inserted in an ear canal, andan electro active polymer adapted such that the outer circumference of the resilient member is responsive to an electric voltage when being applied to the electro active polymer,so that the resilient member can substantially seal the ear canal when inserted.

Abstract
The present invention provides an earphone comprising an electro-active polymer that is adapted such that the outer circumference of a resilient member of the earphone is responsive to an electric voltage, enabling providing essentially sealing the ear canal when the resilient member of the earphone at least partly is inserted in an ear canal of a wearer. The electro-active polymer also enables an improved game and sound experience by providing by synchronizing the outer circumference of the resilient member with the electric signal provided to the earphone.

8. Method for providing an electric voltage to an earphone comprising the steps of:
-
receiving a first electric signal having an essentially constant voltage component, and applying said first electric signal to an electro-active polymer of an earphone, said electro active polymer being adapted such that the outer circumference of a resilient member of the earphone is responsive to the first electric signal, causing the resilient member to substantially seal an ear canal of a wearer when the resilient member at least partly is inserted in the ear canal. - View Dependent Claims (9, 10, 11, 12, 13)
