Abstract
Disclosed herein are methods and systems for providing haptic output on an electronic device. In some embodiments, the electronic device includes an actuator configured to move in a first direction. The electronic device also includes a substrate coupled to the actuator. When the actuator moves in the first direction, the substrate or a portion of the substrate, by virtue of being coupled to the actuator, moves in a second direction. In some implementations, the movement of the substrate is perpendicular to the movement of the actuator.

21. A haptic structure comprising:
-
a substrate; and a haptic actuator, mechanically coupled to the substrate and comprising, a piezoelectric material; and at least one electrode coupled to the piezoelectric material; wherein; an electrical input received by the at least one electrode causes the haptic actuator to bend the substrate; and the substrate includes a channel at least partially surrounding an area of the substrate to which the haptic actuator is mechanically coupled. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. An electronic device comprising:
-
a cover glass with a first side forming an exterior surface of the electronic device; a display having a first side coupled to a second side of the cover glass, the second side of the cover glass opposite to the first side of the cover glass; a first support structure proximate to a second side of the display, the second side of the display opposite to the first side of the display, and the first support structure separated from the second side of the display to form a space between the display and the first support structure; a second support structure coupled to the second side of the display and the first support structure; a backlight assembly positioned at least partially in the space; a haptic structure mechanically linked to the first support structure; a battery positioned in the electronic device proximate to the first support structure and opposite to the display; and a force sensing element positioned between the battery and the first support structure, wherein; the haptic structure is operable to cause a deflection of the cover glass in response to a signal applied to the haptic structure; and the force sensing element is operable to detect an amount of force applied to the cover glass. - View Dependent Claims (30, 31, 32, 33, 34, 35)

36. An electronic device comprising:
-
a cover glass with a first side forming an exterior surface of the electronic device; a display having a first side coupled to a second side of the cover glass, the second side of the cover glass opposite to the first side of the cover glass; a first support structure proximate to a second side of the display, the second side of the display opposite to the first side of the display, and the first support structure separated from the second side of the display to form a space between the display and the first support structure; a second support structure coupled to the second side of the display and the first support structure; a reflector positioned at least partially within the space and coupled to the first support structure; a backlight assembly positioned at least partially in the space, between the reflector and the display; a haptic structure mechanically linked to the first support structure; a battery positioned in the electronic device proximate to the first support structure and opposite to the display; and a force sensing element positioned between the battery and the first support structure, wherein; the haptic structure is operable to cause a deflection of the cover glass in response to an applied signal; the haptic structure is positioned to provide a gap between the force sensing element and the first support structure; and the force sensing element is operable to detect an amount of force applied to the cover glass. - View Dependent Claims (37, 38, 39, 40)
