Suspension element having integrated piezo material for providing haptic effects to a touch screen
First Claim
1. A method of manufacturing a haptic device having a compliant suspension system, the method comprising the steps of:
- coupling a segment of piezo material to at least one surface of a compliant suspension element, wherein the compliant suspension element is a flat bent spring that includes a first end portion, a second end portion, a first compliant portion, a second compliant portion, and an intermediate portion, the first and second compliant portions being bent with respect to and extending between the intermediate portion and the first and second end portions, respectively, and the step of coupling the segment of piezo material to the at least one surface of the compliant suspension element includes coupling the segment of piezo material to the intermediate portion of the flat bent spring;
coupling the intermediate portion of the flat bent spring to a touch screen component; and
coupling the first and second end portions of the flat bent spring to a housing component, wherein the segment of piezo material is configured to produce a force that moves the touch screen component relative to the housing component and thereby provide a haptic effect to a user of the touch screen component and wherein in reaction to the force produced by the segment of piezo material the first and second compliant portions of the flat bent spring are configured to allow movement of the touch screen component relative to the housing component in a first direction while also being configured to limit movement between the touch screen component and the housing component in at least a second direction, the second direction being different than the first direction.

Abstract
Methods of manufacturing a haptic device having a compliant suspension element. Segments of piezo material are coupled to at least one surface of at least one compliant suspension element, and the at least one suspension element is coupled to a touch screen component. The at least one suspension element is also coupled to a housing component. The segments of piezo material are configured to produce a force that moves the touch screen component relative to the housing component and thereby provide a haptic effect to a user of the touch screen component. In reaction to the force produced by the segments of piezo material, the at least one suspension element is configured to allow movement of the touch screen component relative to the housing component in a first direction and to limit movement between the touch screen component and the housing component in at least a second direction.
