Abstract
A haptic device includes an elongated piezo bender supported by a first holder and a second holder. The first holder and the second holder being spaced apart from each other and located at or near opposite ends of the elongated piezo bender. A mass is supported by the elongated piezo bender and positioned in between the first holder and the second holder. The mass has a non-uniform thickness in a direction along a major axis of the elongated piezo bender. An electrical driving signal generator is configured to generate a signal to create a vibration in the elongated piezo bender.
