<p>PROBLEM TO BE SOLVED: To provide a vibration generator which can suppress dissipation current even when a plurality of motors are simultaneously driven. SOLUTION: Two different weight motors 12, 18, each having a weight attached to its rotating shaft, are installed in a case. Driving current flows through the weight motors 12, 18 correspondingly to the periods of pulse signals S12, S18 given by a control section, respectively. Both the pulse signals S12, S18 have waveforms comprising on-times and off-times alternately arranged and are controlled so that the on-time of the weight motor 12 and that of the weight motor 18 do not overlap each other.</p> |
