Title:
PIEZOELECTRIC RESONANCE UNIT, WIRELESS POWER TRANSMISSION SYSTEM AND FILTER
Document Type and Number:
Japanese Patent JP2016046613
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a piezoelectric resonance unit, and a wireless power transmission system and a filter having the piezoelectric resonance unit, capable of achieving miniaturization and a low profile, and enabling stable driving while coping with high power.SOLUTION: A piezoelectric resonance unit includes either one of the following structures: a structure in which a plurality of piezoelectric resonators 11 are connected in parallel; a structure in which a plurality of piezoelectric resonators 11 are connected in series; a structure in which circuits each including a plurality of piezoelectric resonators 11 connected in series are connected in parallel; and a structure in which circuits each including a plurality of piezoelectric resonators 11 connected in parallel are connected in series. The plurality of piezoelectric resonator 11 include piezoelectric materials, and at least in one of the plurality of piezoelectric resonators, piezoelectric is independent.SELECTED DRAWING: Figure 3
