Vibration based on a sound is generated even in a case where the sound does not have a component of a low-frequency region. Envelope information regarding an envelope of a sound signal is derived, a frequency modulation and an amplitude modulation based on the envelope information are performed on a basic signal of waves having constant frequency and constant amplitude, and a vibration signal for vibrating a vibration generation device is generated.

Vibration signal generation device

A vibration control device that while responding to music being played, generates a vibration that gives desired arousal effect and/or relaxing effect regardless of the contents is provided, the vibration control device controlling a vibration device that generates vibration according to the music being played and gives a stimulus to a user includes a vibration signal acquisition unit for acquiring a vibration signal representing the vibration in which a stimulus intensity falls within a predetermined stimulus intensity range, and an output unit for outputting the vibration signal acquired by the vibration signal acquisition unit to the vibration device.

Vibration control device, vibration control method, vibration control program, and recording medium

A desired effect can be exerted on the mental and physical state of a listener of a piece of music with a vibration based on the piece of music even when the piece of music has almost no relaxation or awakening effect. As a vibration signal for vibrating a vibration generation device while the piece of music is being played, the audio signal in the band corresponding to the mode is extracted from the audio signal of the music, and a vibration signal is generated based on the extracted audio signal.

A vibration control device which can make a user recognize a vibration by using a plurality of vibration units appropriately is provided. In a first vibration pattern, by interposing a low-vibration period (Ti) between a first standard vibration period (T) and a second standard vibration period (T), a user recognizes more easily a vibration by a vibration unit which vibrates in the second standard vibration period (T). Therefore, even when the user's weight acts on the vibration unit which vibrates in the second standard vibration period (T) lightly, the vibration of this vibration unit is easily recognized.

Vibration control device

A vibration control device is provided which enables an awakening effect for a user to be increased while making it difficult to give discomfort to the user. A harmonic signal generating section of a vibration control device is configured to successively output a plurality of alternating signals for driving a vibration unit. By way of the plurality of alternating signals which is successively output and has a frequency ratio represented with a predetermined integer ratio, vibration generated with the plurality of alternating signals can more easily awaken a user while making it difficult to give discomfort to the user.
