Abstract
In the use of a touch panel which vibrates in synchronization with a touch operation, discomfort caused by a panel vibration sound is reduced while an operational feeling of a touch operation on the touch panel being maintained. A vibration control device that is used for a touch panel which vibrates in synchronization with a touch operation, includes a sound data acquirer that acquires sound data of a surrounding sound of the touch panel; a predominant frequency acquirer that extracts a predominant frequency of the surrounding sound from the acquired sound data; a consonant sound determiner that determines a consonant sound frequency based on the extracted predominant frequency, the consonant sound frequency being a frequency of a sound which is in consonant with a sound having the extracted predominant frequency; and a vibrational frequency setter that sets a vibrational frequency of the touch panel to the determined consonant sound frequency.
