A vibration generator is provided to increase vibration by enlarging an area where a vibrating member interacts with a driving member and to decrease an operation noise of a vibrator by preventing a vibrating member from colliding with a driving member. A vibration generator includes a case(11), a driving member(12), a vibrating member(13) and a support member(14). The driving member generates an electromagnetic field according to an AC signal from outside. The vibrating member is moved like a pendulum according to the electromagnetic field, which is generated by the driving member. The support member supports the vibrating member, such that the vibrating member is moved within an effective region of the electromagnetic field. The driving member includes a bobbin, around which a coil is wound. A magnetic member, which is fixed at one end of the support member, is insert-fixed on the case. The magnetic member interacts with an alternating polarity of the driving member.
