Vibrating gyroscope and electronic device using the same |
摘要 |
A vibrator that produces bending vibration with both ends unsupported is mounted on one principal surface of a mounting board, and a driving-and-detecting circuit component is also mounted to cross over an antinode center line of bending vibration of the mounting board due to resonance. The original self-resonance frequency of bending vibration of the mounting board itself is lower than the frequency of bending vibration of the vibrator. The modified self-resonance frequency of bending vibration of the mounting board when the vibrator and the driving-and-detecting circuit component are mounted thereon is higher than the original self-resonance frequency, and does not coincide with the frequency of bending vibration of the vibrator.
