Vibration apparatus for a mobile telecommunication terminal and method for controlling the same |
摘要 |
Disclosed is a vibration apparatus for generating vibration in a mobile terminal. The apparatus includes a vibrator for generating vibration; a frequency generator for generating a driving signal having a frequency within a predetermined frequency range in a predetermined time period; a driver for driving the vibrator using the driving signal provided from the frequency generator; and a frequency controller for periodically varying a frequency of the driving signal within the frequency range. Further, the vibration apparatus includes a vibration measurer for measuring vibration generated by the vibrator and providing the measured vibration values to the frequency controller. The frequency controller updates a frequency of the driving signal for driving the vibrator at a frequency indicating a maximum vibration value according to the measured vibration values.
