DEVICE AND METHOD FOR GENERATING VIBRATIONS |
摘要 |
A device and method for generating vibrations in a portable terminal are disclosed. The device for generating vibrations comprises: a haptic actuator which is driven by a driving signal so as to generate vibrations; and a control unit for applying the driving signal to the haptic actuator, causing the haptic actuator to have a high impedance and controlling a start time of the driving signal of non-periodic pulses to be applied to the haptic actuator, on the basis of a counter-electromotive force signal generated by the haptic actuator. |
