Embodiment Construction

[0021] Embodiments of the present invention provide systems and methods for providing haptic feedback at multiple resonant frequencies.

[0022] Illustrative multi-resonance frequency device

[0023] An illustrative embodiment of the invention includes a mobile device, such as a mobile telephone. In the illustrative embodiment, the messaging device includes Immersion's equipped vibrotactile feedback system, previously known as Immersion's Samsung SGH-i710 mobile computer with vibration haptic feedback system. Other messaging devices and haptic feedback systems may be utilized.

[0024] The mobile device includes a touch screen display, local memory, and a processor in communication with each of these elements. The illustrative mobile device also includes a resonator and a piezoelectric actuator coupled to the resonator and in communication with the processor. The piezoelectric actuator is configured to receive a signal from the processor and use the resonator to output ...

Abstract

Systems and methods for providing haptic feedback at multiple resonance frequencies are disclosed. For example, one disclosed apparatus includes a resonator with a base and a plurality of projections, a first projection of the plurality of projections having a first resonance frequency and a second projection of the plurality of projections having a second resonance frequency, and a piezoelectric actuator coupled to the resonator and operable to output a haptic feedback effect at the first resonance frequency and at the second resonance frequency.

Description

[0001] Cross References to Related Applications [0002] This utility patent application claims priority to U.S. Utility Patent Application No. 12 / 580,375, entitled "Systems and Methods for Providing Haptic Feedback at Multiple resonance Frequencies," filed October 16, 2009, the entire contents of which are incorporated by reference method is incorporated into this article. technical field [0003] The present invention relates generally to haptic feedback, and more particularly to systems and methods for providing haptic feedback at multiple resonant frequencies. Background technique [0004] A haptic feedback system vibrating at its resonant frequency may provide several advantages, including enhanced haptic feedback effects and / or more efficient power usage. Conventional haptic feedback systems may utilize multiple actuators each outputting vibration at a different resonant frequency to implement a system with multiple resonant frequencies. However, using multiple actua...
