Exciter and Voice-Coil actuators for general haptic feedback

Touch panels and other smooth user interfaces are easier to use if they acknowledge inputs with a signal. Our exciters and voice coil actuators are haptic components that are attached below the user interface and cause the entire surface to vibrate briefly when touched (global feedback). Exciters work with proven electromagnetic technology and are extremely versatile because they can emit both haptic and acoustic signals. In addition to vibrations, a single component can also be used to generate sounds ranging from simple acknowledgment tones to musical signals.
