Feedback for flat panels

Sound specialist NXT has announced a control module that, when used with two 0.5W moving coil transducers, adds haptic touch to a flat panel whilst simultaneously turning the panel into a loudspeaker.

The module, which measures 10 x 15mm, is designed primarily for applications in white goods, security systems, home automation and industrial control. The haptic effect makes a touch panel feel like a mechanical keypad or keyboard. The NXT HCM-1 module controls the transducers, which generate bending waves across the surface of the panel, creating the sensation of pressing a mechanical key. Because the panel also acts as a speaker, additional confirmation of a positive touch can be provided. A further option is using the module to deliver voice prompts or other messages.
