Abstract
An electronic device such a telephone (100), PDA (600), or pager (800), includes a manually operable input such as an elastomeric key (102, 103) or button (814), or a touch screen (604) that does not by itself provide substantial tactile feedback upon actuation, and also includes an electromechanical transducer (212) that is capable of generating an impulse of mechanical energy that can be felt. In response to detecting actuation of the manually operable input (102, 103, 814, 604), the electromechanical transducer (212) is driven to produce an impulse of mechanical energy that propagates to the manually operable input (102, 103, 814, 604) and provides tactile feedback to a user.
