Sound Generators Using Electroactive Elastomer for Multichannel Audio

Document Thumbnail

To develop sound generators suitable for multichannel audio, we studied the transformation efficiency of electroactive elastomer (EAE), which is soft material whose shape can be transformed by applying voltage. From the results of our analysis, we proposed two types of sound generators, both of which are lightweight because they do not use conventional driving parts. The first type is a cylindrical sound generator that radiates sound omnidirectionally in the horizontal plane using the EAE's flexibility. The second type is a push-pull sound generator with a comparatively improved frequency response by more effective use of the transformation of EAE. The obtained acoustic characteristics and future applications are discussed in this paper.
