Title:
VIBRATORY STRUCTURE AND ACOUSTIC STRUCTURE
Document Type and Number:
Japanese Patent JP2017070042
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To change an attenuation characteristic having a different frequency in the vibration of a vibrator.SOLUTION: A vibratory structure comprises: a vibrator 10; piezo electric elements 121 to 124 mounted to a surface of the vibrator 10; and resonance circuits 161 to 164 that are operated by energy generated in the piezo electric elements 121 to 124 and change an attenuation characteristic of a target frequency in the vibration of vibrator 10. At least two of the resonance circuits 161 to 164 have different target frequencies.SELECTED DRAWING: Figure 1
