| 发明名称 | Vibrating element with an increased amount of change in detuning frequency per unit mass, vibrator, electronic apparatus, and moving object | ||
| 摘要 | A vibrating element includes: drive vibrating arm supported to the base portion and extending in a direction of the second axis; and detection vibrating arm supported to the base portion at a position different from the drive vibrating arm and extending in the direction of the second axis. When the vibrating element is subjected to rotation about the second axis while the drive vibrating arm being reciprocally driven in a direction of the first axis, an amount of displacement of the detection vibrating arm in a direction of the third axis at a position distant from the base portion by a distance y1 along the direction of the second axis is greater than an amount of displacement of the drive vibrating arm in the direction of the third axis at a position distant from the base portion by the distance y1 along the direction of the second axis. | ||

| 主权项 | 1. A vibrating element that, when assuming that a first axis, a second axis and a third axis are mutually orthogonal and intersect each other, comprises: a base portion; at least one drive vibrating arm connected to the base portion and extending in a direction of the second axis; and at least one detection vibrating arm connected to the base portion at a position different from the drive vibrating arm and extending in the direction of the second axis, wherein the vibrating element is configured such that when the vibrating element is subjected to rotation about the second axis while the drive vibrating arm is being reciprocally driven in a direction of the first axis, an amount of displacement of the detection vibrating arm in a direction of the third axis at a position distant from the base portion by a distance y1 along the direction of the second axis is greater than an amount of displacement of the drive vibrating arm in the direction of the third axis at a position distant from the base portion by the distance y1 along the direction of the second axis. | ||
