VIBRATORY PANEL DEVICES AND METHODS FOR CONTROLLING VIBRATORY PANEL DEVICES

摘要

There is provided a method of generating a primary effect in a vibratory panel device comprising at least N + M transducers connected to a panel, where N and M are integers greater than or equal to 1. Each transducer is electrically connected to signal processing circuitry and the signal processing circuitry is configured to receive signals from or provide signals to each transducer. The method comprises: obtaining N electrical signals to be applied respectively to N of the transducers to produce the primary effect; and processing the N electrical signals to produce M additional electrical signal(s), such that when the M signal(s) are applied to respective transducers other than the N transducers, a secondary effect is produced. The secondary effect may be for example cancellation of any audio output resulting from providing haptic feedback.
