Abstract
An apparatus includes a touchscreen keypad and one or more devices that generate a tactile response to a user of the apparatus when a key in the keypad is pressed. In order accomplish a simple construction requiring a minimum of space, the one or more devices that generate that tactile response may include at least one piezoelectric element configured to generate vibration which is forwarded to the user in response to a key of the touchscreen keypad being pressed.

17. An apparatus comprising:
-
one or more piezoelectric elements, the piezoelectric elements configured to generate an alerting sound signal; and a controller coupled to the one or more piezoelectric elements, the controller configured to cause the apparatus to; detect the occurrence of a defined type of event associated with an operation of the apparatus; and emit the alerting sound signal via the one or more piezoelectric elements based on the detected type of event. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
