Summary:A control panel apparatus includes a control panel that is vibrated to generate sound and/or haptic feedback. The control panel apparatus is configured to receive tactile input, such as a touchscreen, and to provide tactile feedback so as to function like a haptic panel, in response to a haptic signal component of a driving signal. The control panel is also configured to function as an audio speaker in response to an audio signal component of the driving signal. The haptic signal has a wider bandwidth, in the range of approximately 100-400 Hz, and the audio signal has a narrower bandwidth, in the range of approximately 20 Hz-20 kHz. The driving signal is configured to include either or both of the haptic signal and the audio signal. One or more drive elements are coupled to a control panel, each drive element driven by a driving signal. Each drive element converts the electrical driving signal to mechanical movement, thereby vibrating the control panel. In the case of multiple drive elements, each drive eleme
