DEVICE AND METHOD FOR GENERATING VIBRATION IN WIRELESS TERMINAL

摘要

PURPOSE: A device and method for generating vibration in a mobile terminal are provided to maximize a haptic effect by combining a visual UI with a vibration level. CONSTITUTION: If some parts of a touch screen area is touched, a plurality of piezoes corresponding to the touch area detects power polarity and power frequency(201,202). The power frequency and polarity of the piezoes are changed into the detected power polarity and power frequency(203). If vibration waves are generated by a power frequency or polarity of the changed piezoes, the vibration level is generated by the overlapping increase or the canceling decrease(204,205).
