Abstract:This contribution presents a theoretically investigation of dielectric elastomer loudspeakers similar in design to the loudspeakers studied at SRI International more than 10 years ago. The main emphasis of the contribution is on the effect of dissipative effects, specifically radiative losses (acoustic losses). The starting point of the theoretical model is a free-energy description and include hyper-elastic contributions. In the designs considered in this work the dielectric elastomer material is subject to a… Show more
