Vibration-sensing element and vibration-sensing gyro using the same |
摘要 |
The invention provides a vibration-sensing gyro, where resonance frequencies of tines are adjusted adequately in a simple manner. A vibration-sensing gyro (10) of the invention is made of a light alloy plate like duralumin and includes a first tine (14) and a second tine (16) disposed parallel to each other and projecting from a base (12). When the first tine (14) has a length l1, a width w1 along the X axis, and a thickness t1 and the second tine (16) has a length l2, a width w2 along the X axis, and a thickness t2 (=t1), the first tine (14) and the second tine (16) hold the relationship of l2/ 2ROOT t2=l1/ 2ROOT w1. In other words, the tines (14,16) and the base (12) are manufactured to satisfy this relationship. Such definition of the dimensions makes a resonance frequency fx1 of the first tine along the X axis coincide with a resonance frequency fy 2 of the second tine 16 along the Y axis.
