Signal generation device, signal generation method, and signal generation program

A method for generating a waveform signal for causing a target object to vibrate according to a phenomenon, the method comprising:

• acquiring first envelope information indicative of a first envelope of a first waveform signal corresponding to a first phenomenon;
• acquiring second envelope information indicative of a second envelope of a second waveform signal corresponding to a second phenomenon;
• generating a composite envelope obtained by synthesizing the respective envelopes based on the first envelope information and the second envelope information;
• and
• modulating a force wave based on the composite envelope to generate the waveform signal that causes the target object to vibrate.

A signal generation program that configures a signal generation device to generate a waveform signal for causing a target object to vibrate according to a phenomenon, the signal generation program that, when executed by a processor of a computer, configures the signal generation device to:

• acquire first envelope information indicative of a first envelope of a first waveform signal corresponding to a first phenomenon;
• acquire second envelope information indicative of a second envelope of a second waveform signal corresponding to a second phenomenon;
• generate a composite envelope obtained by synthesizing the respective envelopes based on the first envelope information and the second envelope information;
• modulate a force wave by the composite envelope to generate the waveform signal that causes the target object to vibrate.
