Abstract:
Provided is a low frequency vibrating actuator device. The low frequency vibrating actuator device includes a substrate including a pair of connection electrodes, an actuator provided on the pair of connection electrodes to generate vibration, a support provided on the actuator, a vibration membrane provided on the support to vibrate according to the actuator, and a vibrating mass provided on the vibration membrane to vibrate according to the vibration membrane. The actuator includes a plurality of laminated insulating layers and internal electrodes that are alternately laminated between the insulating layers adjacent to each other, and a top surface of the support, which contacts the vibration membrane, has an area that is equal to or less than that of a bottom surface of the support, which contacts the actuator.
