Document Type and Number:
Japanese Patent JP2923467
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a supporting device of a piezoelectric transformer which can support part of a vibration node with proper freedom corresponding to change the number of vibrations and change a driving voltage by a small num ber of parts. SOLUTION: This device is provided with a first supporting member 70 consisting of a thin plate-like member with a containing recessed part 72 which can contain a piezoelectric transformer 85 and a second supporting member 71 consisting of a thin plate-like member which closes an opening part of the containing recessed part 72 of the first supporting member 70. At least one of the first supporting member 70 or the second supporting member 71 is provided with section part supporting projecting parts 75, 76 with elasticity at a position corresponding to part of a vibration node of the piezoelectric transformer 85. The device is constituted so that part of a vibration node of the piezoelectric transformer 85 is held by the section part supporting projecting parts 75, 76. As a result, a conventional substrate is unnecessary, the number of parts is reduced and the part of the vibration node can be supported with proper freedom without restraining vibration by fixedly restricting it.
