Beschreibung
Zusammenfassung:	The invention relates to an apparatus (1) comprising a keypad (2), and means for generating a tactile response to a user of the apparatus when a key in said keypad is pressed. In order accomplish a simple construction requiring a minimum of space, said means for generating a tactile response include at least one piezoelectric element (3) arranged to generate vibration which is forwarded to the user via a key when said key is pressed.
