Claims18
1-13. (canceled)
A vibration device, comprising:
- a vibrator that imparts vibration;
- a displacement detection section that detects displacement of the vibrator;
- and
- a controller that causes the vibrator to vibrate based on an input drive signal and detection information of the displacement detection section,
- wherein:
- the vibrator generates magnetic flux;
- the displacement detection section is a magnetic detection sensor that detects the magnetic flux;
- and
- the magnetic detection sensor is provided at a side face of a housing.
