Title:
CRYSTAL OSCILLATOR AND CRYSTAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/112962
Kind Code:
A1
Abstract:
Provided are a crystal oscillator and a crystal device with which an electrical signal that is in accordance with vibration can be obtained at a more appropriate ESR. A crystal oscillator (12) comprises: a crystal piece (121) that has a resonant frequency of 100 MHz or higher; two excitation electrodes (122) to which a voltage relating to the resonance of the crystal piece (121) is applied; two mounting electrodes (124) that are located offset toward the side of one end of the crystal piece (121), and are connected to an external part; and two extraction electrodes (123) that connect the respective excitation electrodes (122) and mounting electrodes (124). The centers of the excitation electrodes (122) are located further to the side that is close to the mounting electrodes (124) than the location of the center of the crystal piece (121), and the two extraction electrodes (123) are connected between the excitation electrodes (122) and the mounting electrodes (124) in straight lines that are not parallel to one another.
