Research Abstract	A speaker using dielectric elastomer type of electroacitive polymer "artificial muscle" was tested in air. The directivity and frequency response were 120 deg. and from 400 to 3000 Hz respectively. The sensitivity were kept after continuous projection test for 1 hour. Test piece of the artificial muscle were operable in hydrostatic pressure at 10,000 m depth, and the special speaker for underwater use could project sonic waves in water.
