摘要： PROBLEM TO BE SOLVED: To obtain satisfactory oscillation characteristics by confining energy in a principal surface part of a mesa-structure crystal oscillator.SOLUTION: A crystal oscillator 10 is formed of: a mesa-structure crystal piece 1 including a principal surface part 11 and an edge part 12 which surrounds the principal surface part 11, a thickness of the edge part 12 being less than that of the principal surface part 11; and a pair of exciting electrodes 21, 22 formed in a principal surface part 11 on one side of the crystal piece 1 and a principal surface part 11 on the another side thereof, respectively. In the crystal piece 1, protrusions 31 is provided in a sidewall portion 13 of the principal surface part 11 over all the periphery of the sidewall portion 13 so as to surround the exciting electrodes 21, 22. When an oscillation wave or a reflection wave excited by the crystal oscillator 10 reaches a region in which the protrusions 31 are formed, the oscillation wave or the reflection wave is irregularly reflected after changing the propagation direction thereof and gradually attenuated. Therefore, by providing the protrusions 31 in the crystal piece 1, oscillation different from main oscillation is suppressed and energy is confined in the principal surface part, thereby improving oscillation characteristics.

摘要： PROBLEM TO BE SOLVED: To provide a piezoelectric vibrator that restrains the generation of sub vibration.SOLUTION: Regarding a crystal oscillator 1 in which excitation electrodes 21 and 22 are formed on both surfaces of a crystal piece 10 whose main vibration is thickness-shear vibration, sub vibration restraint parts 25 whose crystal axis is reversed by heat treatment are formed at a position where sub vibration such as contour-shear vibration and curvature vibration occurs on the crystal piece 10. The sub vibration restraint parts 25 are preferably provided two or more in a punctate state and symmetrically relative to the excitation electrode 21. Because these sub vibration restraint parts 25 move the oscillation frequency of the sub vibration to a lower frequency side at the position, they suppress an adverse effect on the main vibration of the crystal oscillator 1. Thus, the crystal oscillator 1 with a stable frequency characteristic can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a technique capable of configuring a crystal oscillator of a simple configuration, suppressing an influence of one vibration region upon another vibration region in a crystal resonator having a plurality of vibration regions.SOLUTION: The crystal resonator is configured to provide: a first vibration region disposed on a crystal piece; a second vibration region disposed on the crystal piece and having thickness and positive and negative directions of an X-axis different from those of the first vibration region; and excitation electrodes respectively disposed in the first vibration region and the second vibration region to make each vibration region vibrate independently. From the one vibration region and the other vibration region, frequencies varying with different magnitude relative to a temperature change can be extracted.
