Title:
METHOD FOR SAVING VIBRATION PATTERN OF RESONANCE-FREE FREQUENCY VIBRATION MOTOR
Document Type and Number:
WIPO Patent Application WO/2012/050361
Kind Code:
A2
Abstract:
The present invention relates to a method for actuating a vibration motor, and more particularly, to a method for saving various formats of vibration pattern data of a vibration motor by using only an initial vibration frequency, change in vibration frequency, and the total number of vibrations. The method for saving a vibration pattern data, according to the present invention, can express various vibration patterns with a small amount of data by expressing various vibration patterns of a resonance-free frequency vibration motor in terms of the initial vibration frequency, the size of change in the vibration frequency, and the total number of vibrations necessary for reaching the final vibration frequency. In addition, the method for saving vibration pattern data, according to the present invention, can allow manufacturing of a user terminal enabling a haptic function at low cost by expressing the vibration pattern of the resonance-free frequency vibration motor with little data and low data processing speed.
