MOTOR DRIVING DEVICE, DRIVING METHOD, AND INPUT DEVICE

Title:

MOTOR DRIVING DEVICE, DRIVING METHOD, AND INPUT DEVICE

Document Type and Number:

Japanese Patent JP2012080714

Kind Code:

A

Abstract:

To provide a motor driving device capable of achieving a desired vibration waveform and to provide an input device using the same.

The input device 100 includes a touch panel (input operation section) 1, an input determination section 2, a motor driving device (driving device) 3, a motor 4, and a vibration section 5. The driving device 3 includes a target waveform generation section 11, an acceleration sensor (vibration detection section) 12, a waveform shaping section 13, and an amplification section (driving signal generation section) 14. The acceleration sensor 12 is provided to detect an actual vibration waveform of the vibration section 5 for feedback control so that the actual vibration waveform approaches a target vibration waveform, thus achieving a target vibration waveform with higher accuracy.
