摘要:
An electroactive loudspeaker includes a conductive carrier plate comprising a first main surface and a second main surface, the first main surface and the second main surface being disposed on opposite sides of the carrier plate. The electroactive loudspeaker further includes an electroactive polymer layer comprising a first main surface and a second main surface. An electrically conductive electrode layer is attached to the second main surface of the electroactive polymer layer. The first surface of the carrier plate has an area and the first surface of the electroactive polymer layer has an area, the area of the first surface of the carrier plate being larger than the area of the first surface of the electroactive polymer layer. The first main surface of the electroactive polymer layer overlaps in its entire area with the first main surface of the carrier plate.
