Patent ID: 7301094

Claim:
A vibration source driving device comprising: a sound source for generating a musical tone signal in response to music data and for generating a vibration signal in synchronization with rhythm data within the music data; at least one digital to analog converter (DAC) to perform digital to analog conversion on an output of the sound source selected from the group consisting of the musical tone signal and the vibration signal; a vibration source that provides a first vibration system for causing resonance in a first frequency band and a second vibration system for causing resonance in a second frequency band that is lower than the first frequency band, so that the first vibration system generates sound, and the second vibration system generates vibration; a rhythm data detection means for detecting rhythm data from the musical tone signal output from the sound source, thus outputting the rhythm data to the sound source to cause the sound source to generate the vibration signal in synchronization with the rhythm data; a high-pass filter for eliminating low-frequency sounds from the musical tone signal; a low-pass filter for eliminating higher harmonics components from the vibration signal; an addition means for adding together an output signal of the high-pass filter and an output signal of the low-pass filter; and a drive means for driving the vibration source based on an output signal of the addition means.
