<P>PROBLEM TO BE SOLVED: To provide a vibration generator which can resonate a vibrator with different natural frequencies in different directions by using one kind of coil. <P>SOLUTION: A magnetic core around which a coil is wound is mounted on the vibrator and the vibrator is supported so as to resonate in an X direction and a Z direction with different natural frequencies. In a cabinet, a first magnet 43a and a second magnet 44a facing each other are provided at an end 21b of the magnetic core. In the first magnet 43a and the second magnet 44a, magnetic pole surfaces facing the magnetic core are magnetized to mutually different polarities. The center O1 of the first magnet 43a and the center O2 of the second magnet 44a are located apart from each other in the X direction and in the Z direction. The magnetic core at a neutral attitude has a center O0 located in the middle of the center O1 and the center O2. The vibrator is resonated in the X direction by a component force Fx of driving force F and is resonated in the Z direction by a component force Fz. <P>COPYRIGHT: (C)2012,JPO&INPIT |
