Patent ID: 8653352

Claim:
A vibration generator comprising: a vibration mechanism unit including a vibrating body having a predetermined mass, an elastic support member that supports the vibrating body, and a drive unit that exerts a vibration force on the vibrating body; and a drive circuit unit that drives the vibration mechanism unit, wherein the drive circuit unit includes a sound data extraction unit that extracts sound data of any musical instrument from music information in which sound data of a plurality of musical instruments is mixed, a section extraction unit that extracts, from the extracted sound data, a data section in which a level is equal to or higher than a predetermined value or exceeds the predetermined value, and a pulse conversion unit that outputs, during the extracted data section, a drive pulse of a certain frequency for driving the vibrating body at a natural vibration frequency or at a vibration frequency approximate thereto, wherein the music information is analog information, and the sound data extraction unit is a band-pass filter that extracts sound data a frequency of which corresponds to any musical instrument, wherein the vibration mechanism unit has the vibrating body that vibrates at a plurality of natural vibration frequencies, the sound data extraction unit individually extracts sound data of the plurality of musical instruments from the music information, and the pulse conversion unit prepares a plurality of drive pulses for driving the vibrating body at a different natural vibration frequency or at a vibration frequency approximate to the different natural vibration frequency, whereby different drive pulses are output to each data section among a plurality of data sections obtained from different sound data pieces.
