More Information
Summary:A touch assembly includes: an outer tip; an inner tip; a circuit board; a vibration sensor; and a spring element. The outer tip includes a distal end defining an outer contact surface. The inner tip: is arranged concentrically within the outer tip; extends from the distal end of the outer tip; and defines an inner contact surface. The circuit board is arranged over a proximal end of the outer tip. The spring element: is interposed between the circuit board and the inner tip; couples the inner tip to a reference potential; and is configured to, during a haptic feedback cycle at a touch sensor in response to application of the inner tip toward the touch sensor, yield to locate the inner contact surface coplanar with the outer contact surface. The vibration sensor is arranged on the circuit board and configured to output vibration signals during the haptic feedback cycle.
