发明名称 Piezoelectric user interface
摘要 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.

主权项 1. An apparatus comprising: a touchscreen keypad; a plurality of piezoelectric elements, each configured to generate a vibration which is forwarded to a user of the apparatus via the touchscreen keypad; and a controller coupled to the touchscreen keypad and each of the plurality of piezoelectric elements, the controller configured to cause the apparatus to: detect the user pressing a selected key of the touchscreen keypad;determine a selected one of the plurality of piezoelectric elements that is closest to the selected key; andgenerate a tactile response via the selected piezoelectric element that causes only a region close to the selected key to vibrate, the region including the selected key.
