Patent number: 11669167Abstract: The present implementations relate to a support structure for an input device that supports deflection of an input surface responsive to input forces exerted thereon and vibration of the input surface responsive to haptic feedback generated by a haptic actuator. The support structure includes one or more fixed structures mounted to a housing and a dynamic surface mounted to a sensor layer of the input device. A number of first deformable segments cantilever from the one or more fixed surfaces and deflect in a vertical direction when an input force is exerted on the sensor layer, where the input force is orthogonal to the input surface. A number of second deformable segments connect the plurality of first deformable segments to the dynamic surface and deflect in a horizontal direction when shear forces are exerted on the dynamic surface, where the shear forces are parallel to the input surface.Type: GrantFiled: October 21, 2021Date of Patent: June 6, 2023Assignee: Synaptics IncorporatedInventors: Yeh-Cheng Tan, Yi-Yun Chang
