Title: Vibration generator
Inventor: MATSUOKA KAZUNARI
IPC: G08B6/00
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To obtain a vibration generator which can obtain a large vibration without increasing the power consumption in a coil, by a method wherein a pulse signal is turned on and off so as to be set as an ON period < on OFF period. SOLUTION: Pulses applied to a coil at a vibration generator are turned on and off so as to be set as an ON period < OFF period. That is to say, a driving force at a time when the ON period of the coil is a period (a) is S(a), and a driving force at a time when the ON period of the coil is a period (b) is S(a)-S(b). At this time S(a) is a driving force to which a moving permanent magnet is subjected from the coil in the period (a), and S(b) is a negative driving force to which the moving permanent magnet is subjected from the coil up to the right end of the period (b) from a position of 1.5 mm from the center. As a result, the loss of S(b) is eliminated, the driving force S(a) in the period (a) is used effectively as the driving force of the moving permanent magnet, the power consumption of the coil is not changed totally, and a large vibration can be obtained.
