A Thin and Flexible Sound Generator Using an Electroactive Elastomer
We propose a new sound generator using electroactive elastomer (EAE), which is an elastic and flexible material. Our prototype sound generator is composed of a thin polyurethane elastomer sheet and conducting polymer electrodes. The electrodes are formed on both surfaces of the elastomer sheet and are driven by audio signals with a DC bias voltage. We conducted a transformation analysis of the EAE and found that using of the side-length change is more effective than using the thickness change. An EAE sound generator provides 30 dB higher sound pressure level (SPL) at 1 kHz than one using thickness change. The configuration design and operating conditions suitable for a sound generator are discussed.
