Abstract
An actuator assembly for use in an electronic device is provided. The actuator assembly includes a support tray formed of a conductive metal and defining an aperture extending through the support tray. A seat surrounds the aperture and supports an actuator. The actuator includes a piezoelectric element adhered to a metal substrate larger than the piezoelectric element. The metal substrate bends when the piezoelectric element contracts and expands in response to changes in the charge of the piezoelectric element. An insulator is disposed between the metal substrate and the support tray which electrically insulates the substrate from the metal substrate.
