Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a parametric speaker which is for obtaining the reproduced audible sound of a high sound pressure in a desired range and position while miniaturizing the entire apparatus, and is excellent in assembleability and maintainability. SOLUTION: A plurality of ultrasonic vibrators are mounted on the same long-length substrate to configure an ultrasonic vibrator module, and a reflecting plate is provided on a position right facing the respective ultrasonic vibrators of the ultrasonic vibrator module. After ultrasonic waves radiated from the ultrasonic vibrators are reflected by the reflecting plate, then reflected sound waves are combined and the audible sound is reproduced.
