Abstract

Dielectric elastomer electroactive polymer (EAP) loudspeakers have been built and demonstrated at SRI International. Dielectric elastomer loudspeakers have the advantages of being very lightweight and able to conform to any shape or surface, making them attractive as low-profile, surface-mounted speakers in rooms or vehicle interiors, and for applications in active noise control. Loudspeaker performance depends on a number of mechanical factors, such as speaker shape and mechanical bias, as well as on electrical driving characteristics. This paper discusses important aspects of loudspeaker performance, including sound pressure level and directivity.
