Haptic - Control electronics products
HiWave offers HIHCM-001, a 15mm x 10mm control module that, in combination with two moving coil transducers, adds haptic touch to flat panels whilst simultaneously turning the panel into a loudspeaker. The module 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 HIHCM-001 module controls the transducers, which generate bending waves across the surface of the panel, creating the sensation of pressing a mechanical key when a user touches it. The touch panel also acts as a flat-panel speaker, using the same drive module and transducers. The speaker can be used to provide additional confirmation of a positive touch on the panel audible confirmation of other circuit functions being activated, voice feed prompts, advertising messages, or entertainment.
The use of two transducers results in even dispersion of signal strength across the whole touch panel.
HiWave is developing additional drive modules for displays, multi-touch feedback and alternative transducer types. Higher power versions for large displays are also planned.
