Zusammenfassung:	PURPOSE: An underwater sound generating apparatus for decoying vessel sonar is provided to laminate a ring type piezoelectric ceramic vibration body in order to form a sound generation part, thereby enabling to apply to a self-propelling vessel sonar decoy. CONSTITUTION: A self-propelling vessel sonar decoy generates non-directional sound to a circumferential direction from an electrical signal in a sound generation part(10). The sound generation part is comprised by laminating a plurality of ring type piezoelectric ceramic vibration bodies(11). A signal amplification part(20) amplifies the electrical signal from a signal transmission unit of the self-propelling vessel sonar decoy and applies the electrical signal to the sound generation part. A supporting structure(30) supports the sound generation part. A sound window(40) is included in the outside of a radial direction of the supporting structure and protects the sound generation part from seawater and external impacts.
