Abstract
A signal generation device that generates a waveform signal to cause a target object to generate a vibration according to a phenomenon. The device includes an envelope information acquisition unit that acquires first envelope information indicative of a first envelope of a first waveform signal corresponding to a first phenomenon, and second envelope information indicative of a second envelope of a second waveform signal corresponding to a second phenomenon. The device also includes a synthesis unit that generates a composite envelope obtained by synthesizing the envelopes based on the first envelope information and the second envelope information; and a modulation unit that modulates a force wave by the composite envelope to generate the waveform signal.
