Title:
PIEZOELECTRIC GENERATOR
Document Type and Number:
Japanese Patent JP2019220795
Kind Code:
A
Abstract:
To provide a piezoelectric vibration generator with high reliability by corresponding to a low cost and a miniaturization.SOLUTION: A piezoelectric generator comprises: a rectangular parallelepiped shape base 2 made of an insulation material and having a housing part in which one opening part and a middle step are formed; a rectangular shape piezoelectric oscillation element 3 arranged in an inner bottom surface of the hosing part of the base 2 and forming an excitation electrode; a rectangular integrated circuit element 4 arranged in the middle part of the housing part of the base 2 and having a main surface area larger than the piezoelectric oscillation element 3; and a lid 5 hermetically sealing the opening part of the base 2. On the inner bottom surface of the housing part of the base 2, both end parts of the piezoelectric oscillation element 3 are bonded, and in a situation that the integration circuit element 4 covers the piezoelectric oscillation element 3, both end parts of the integration circuit element 4 are bonded in the middle step of the housing part of the base 2.SELECTED DRAWING: Figure 1
