ELECTRONIC DEVICE AND VERIFICATION METHOD

摘要

An electronic device that includes a drive controller being configured to drive a vibrating element by using a drive signal causing the vibrating element to generate a natural vibration in an ultrasound-frequency-band in a touch 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 in accordance with a travel distance of a position of a erformed onto the touch surface, a first memory configured to store first data representing a first passcode corresponding to a number of times the natural vibration is switched between the strong level and the weak level, and a first verification part configured to verify a number of times the drive controller switches the natural vibration between the strong level and the weak level with the first passcode when the touch is performed onto the touch surface.

1. An electronic device comprising:
a top panel having a manipulation input surface; a position detector detecting a position of a manipulation input performed on the manipulation input surface; a vibrating element generating a vibration in the manipulation input surface; a drive controller being 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 in accordance with a travel distance of a position of a manipulation input performed onto the manipulation input surface; a first memory configured to store first data representing a first passcode corresponding to a first number of times the natural vibration is switched between the strong level and the weak level; and a first verification part configured to verify a second number of times the drive controller switches the natural vibration between the strong level and the weak level with the first passcode represented by the first data when the manipulation input is performed onto the manipulation input surface.
