PROBLEM TO BE SOLVED: To provide an air-conditioner having a simple mechanism for generating ultrasonic waves of any waveform. SOLUTION: The air-conditioner 100 for performing air-conditioning operation to supply conditioned air into a room comprises a first piezoelectric buzzer 82a, a second piezoelectric buzzer 82b, and a third piezoelectric buzzer 82c. The first piezoelectric buzzer 82a irradiates the room with first ultrasonic waves. The second piezoelectric buzzer 82b irradiates the room with second ultrasonic waves. The third piezoelectric buzzer 82c irradiates the room with third ultrasonic waves. COPYRIGHT: (C)2005,JPO&NCIPI |
