PIEZOELECTRIC OSCILLATOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18586004 titled 'PIEZOELECTRIC OSCILLATOR

The patent application describes a piezoelectric oscillator with a piezoelectric vibrating element, first and second excitation electrodes, and two crystal substrates bonded to the piezoelectric strip.

  • The first crystal substrate has a principal surface defined by a first basic axis and a second basic axis that intersects the first axis.
  • When the third crystallographic axis of the material of the first crystal substrate is inclined around the first axis by a predetermined angle, it forms a first inclined axis corresponding to the second basic axis.
  • The predetermined angle ranges from -90 to -60 degrees and 80 to 90 degrees.

Original Abstract Submitted

A piezoelectric oscillator includes: a piezoelectric vibrating element having a piezoelectric strip, a first excitation electrode, and a second excitation electrode; a first crystal substrate bonded to the piezoelectric strip; and a second crystal substrate bonded to the piezoelectric strip. The first crystal substrate has a principal surface defined by a first basic axis and a second basic axis that intersects the first basic axis, and when an axis obtained by inclining, among mutually intersecting first, second, and third crystallographic axes of a material of the first crystal substrate, the third axis around the first axis by a first predetermined angle is regarded as a first inclined axis, the first axis corresponds to the first basic axis and the first inclined axis corresponds to the second basic axis, the first predetermined angle is any angle included in an angle range of −90 to −60 degrees and 80 to 90 degrees.
