Title:
APPARATUS AND METHOD FOR PRODUCING STRUCTURAL AND ACOUSTIC VIBRATION
Document Type and Number:
Japanese Patent JP3580931
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To maximize a generating efficiency of induced vibration by activating a structural vibration or an acoustic vibration in real time and detecting the vibration so as to make an exciting frequency in matching with an object frequency at all times.
SOLUTION: The generating device has an actuator means 12 that is fitted to a housing 16, a sensor means 14 fitted to the housing 16, and an electronic module 18 connecting the actuator means 12 and the sensor means 14, and a self-exciting vibrator that generates a vibration signal in the housing. The actuator means 12 creates a vibration signal in the housing 16. The sensor means 14 detects a vibration signal created by the actuator means 12. The electronic module 18 amplifies and shifts a phase of the vibration signal detected by the sensor means 14 and including the resonance mode of the vibration of the housing 16. Then the electronic module 18 gives the amplified signal whose phase is shifted to the actuator means 12 to emphasize the vibration of the housing 16 in the main bode.
