Abstract
A technology for implementing a finer button click of a device including an LRA by reducing the falling time of an LRA after a click is implemented by controlling an input signal applied to the LRA depending on an operating characteristic of the LRA. A user's operational convenience can be improved by omitting a real button positioned in the front part of a mobile phone, and more smooth display watching and manipulation are made possible by increasing the size of a display. Furthermore, the button click of a device including an LRA can be realistically implemented by controlling only the frequency of an input signal without adding a separate device or a control circuit to the LRA.
