DRIVING METHOD FOR VIBRATION ACTUATOR AND PORTABLE MACHINERY

摘要

PROBLEM TO BE SOLVED: To enhance a calling-out function without increasing the amplitude of vibration output.

SOLUTION: A melody pattern is provided to vibration output when a vibration actuator (10) having a vibration output function is driven. It is preferable to vary the frequency of a vibration output within a range of 100-250 Hz according to the melody pattern. Further, the vibration actuator is mounted on portable machinery enabling calling-out and a plurality of melody patterns are prepared to be preferably alloted to a partner for calling out the portable machinery.
