1. A vibration generating device comprising:
a housing;
a vibration body accommodated in the housing;
an elastic support member fixed to the housing and configured to support the vibration body so as to be able to vibrate; and
a driver configured to apply a vibration force to the vibration body, wherein
the elastic support member includes:
a vibration plate portion configured to support the vibration body;
a front fixed plate portion disposed in front of the vibration plate portion and fixed to the housing;
a rear fixed plate portion disposed behind the vibration plate portion and fixed to the housing;
a first elastic plate portion shaped as a flat plate and configured to connect one end of a left end and a right end of the vibration plate portion to the front fixed plate portion; wherein the first elastic plate portion includes, an inner plate portion extending in orthogonal direction from the vibration plate portion, an outer plate portion extending in orthogonal direction from the front fixed plate portion via a fold line, and a connecting portion extending in orthogonal direction from the outer plate portion and connecting the inner plate portion with the outer plate portion; and
a second elastic plate portion shaped as a flat plate and configured to connect the other end of the left end and the right end of the vibration plate portion to the rear fixed plate portion, wherein the second elastic plate portion includes, and inner plate portion extending in orthogonal direction from the vibration plate portion, an outer plate portion extending in orthogonal direction from the rear fixed plate portion via a fold line, and a connecting portion extending in orthogonal direction from the outer plate portion and connecting the inner plate portion with the outer plate portion, wherein
the first elastic plate portion is isolated from the rear fixed plate portion, and the second elastic plate portion is isolated from the front fixed plate portion.
