| 摘要 |
The invention relates to an acceleration and displacement sensor having a position signal generator (20), a signal-detecting and arithmetic unit (30), a power supply unit (40) and a rolling ball (50). The position signal generator (20) forms a closed space for defining the movement path of the rolling ball (50). The position signal generator (20) includes a plurality of sensing terminals (22) aligned to one another in axial direction. Each sensing terminal (22) represents a certain position signal value. The position signal value of the sensing terminal (22), where the rolling ball (50) is located, is continuously given to the signal-detecting and arithmetic unit (30). When the rolling ball (50) is forced to move in axial direction, the signal-detecting and arithmetic unit (30) calculates a displacement value and an acceleration value. <IMAGE>
