DRIVE CONTROL APPARATUS, ELECTRONIC DEVICE AND DRIVE CONTROLLING METHOD

摘要

A drive control apparatus that drives a vibrating element of an electronic device including a display part, a top panel disposed on a display surface side of the display part and having a manipulation input surface, a position detector detecting a position of a manipulation input performed on the manipulation input surface, and the vibrating element generating a vibration in the manipulation input surface, including a drive controller configured to drive the vibrating element by using a drive signal causing the vibrating element to generate a natural vibration in ultrasound-frequency-band in the manipulation input surface, the drive controller being configured to drive the vibrating element so as to switch the natural vibration between a strong level and a weak level for a designated period of time when a travel distance of a position of the manipulation input performed onto the manipulation input surface reaches a designated travel distance.

1. A drive control apparatus that drives a vibrating element of an electronic device including a display part, a top panel disposed on a display surface side of the display part and having a manipulation input surface, a position detector detecting a position of a manipulation input performed on the manipulation input surface, and the vibrating element generating a vibration in the manipulation input surface, comprising:
a drive controller configured to drive the vibrating element by using a drive signal causing the vibrating element to generate a natural vibration in an ultrasound-frequency-band in the manipulation input surface, the drive controller being configured to drive the vibrating element so as to switch the natural vibration between a strong level and a weak level for a designated period of time when a travel distance of a position of the manipulation input performed onto the manipulation input surface reaches a designated travel distance.
