Haptic response apparatus for an electronic device
First Claim
1. A user input for electronic device, comprising:
- a touch sensitive user interface having a continuous fascia and one or more sub-layers;
a controller coupled to the touch sensitive user interface, and configured to detect user contact with the touch sensitive user interface;
a haptic feedback layer coupled to the controller and disposed beneath the touch sensitive user interface, the haptic feedback layer comprising;
a chassis defining a perimeter of the haptic feedback layer;
a plurality of oppositely facing, interlaced cantilever beams emanating from the chassis and spanning across at least a portion of the haptic feedback layer; and
one or more piezoelectric actuators, responsive to the controller and coupled to the plurality of oppositely facing, interlaced cantilever beams;
wherein when the controller detects the user contact, the controller causes at least one of the one or more piezoelectric actuators to actuate.

Abstract
A user input for an electronic device includes a haptic feedback layer (100) and a touch sensitive user interface (200). The haptic feedback layer (100) provides a tactile response to a user when the user actuates a user actuation target (301) on the touch sensitive user interface (200) to simulate a popple-style button. The haptic feedback layer (100) includes a chassis (101) and a plurality of oppositely facing, interlaced cantilever beams (105,106) emanating therefrom, further separated by a support beam (113), and spanning at least a portion of the haptic feedback layer (100). One or more piezoelectric actuators (119) are coupled to the cantilever beams and are responsive to a controller (201). When the controller detects user actuation of the touch sensitive user interface (200), the controller (201) causes at least one of the piezoelectric actuators to actuate in accordance with an actuation signal.
