Abstract: A portable electronic device is described in this disclosure. The portable electronic device can take many forms including for example a smart watch, a smart phone, or a tablet computing device. The portable electronic device can include a device housing component; and a display assembly coupled to the device housing component. The display assembly includes a protective cover that shields a display component from damage. The portable electronic device also includes an actuator configured to apply a vibratory input to the display assembly. In some embodiments, the actuator contacts both the device housing component and the protective cover of the display assembly. In some embodiments, the actuator is affixed only to an interior-facing surface of the display component.

Abstract: A piezoelectric actuator including an upper piezoelectric bimorph beam having a first upper piezoelectric layer, a second upper piezoelectric layer and at least three upper electrode layers extending between a first end and a second end of the upper piezoelectric bimorph beam; a lower piezoelectric bimorph beam having a first lower piezoelectric layer, a second lower piezoelectric layer and at least three lower electrode layers extending between a first end and a second end of the lower piezoelectric bimorph beam, and wherein the first end of the lower piezoelectric bimorph beam is coupled to the first end of the upper piezoelectric bimorph beam by a first joint, and the second end of the lower piezoelectric bimorph beam is coupled to second end of the upper piezoelectric bimorph beam; and a base member coupled to a center region of the lower piezoelectric bimorph beam.
