1. An apparatus comprising:
- one or more piezoelectric elements; and
a controller coupled to the one or more piezoelectric elements, wherein each of the one or more piezoelectric elements is separately controlled by the controller, the controller configured to cause the apparatus to;
detect the occurrence of a defined type of event associated with an operation of the apparatus, wherein the defined type of event comprises an incoming call;
select at least one waveform from a set of waveforms based on the detected type of event, wherein the set of waveforms provides different alerting sound signals each representing the occurrence of the defined type of event; and
provide the selected at least one waveform to the one or more piezoelectric elements to emit a particular alerting sound signal and provide a vibration in response to the incoming call, wherein the particular alerting sound signal comprises a multichannel stereo signal based on the one or more piezoelectric elements separately controlled by the controller.

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.

7. A method comprising:
-
detecting, via a controller, the occurrence of a defined type of event associated with an operation of an apparatus, wherein the defined type of event comprises an incoming call; selecting, via the controller, at least one waveform from a set of waveforms based on the detected type of event, wherein the set of waveforms provides different alerting sound signals each representing the occurrence of the defined type of event; and providing the selected at least one waveform to one or more piezoelectric elements to emit a particular alerting sound signal and provide a vibration in response to the incoming call, wherein each of the one or more piezoelectric elements is separately controlled by the controller, wherein the particular alerting sound signal comprises a multichannel stereo signal based on the one or more piezoelectric elements separately controlled by the controller. - View Dependent Claims (8, 9, 10, 11, 12)
