A vibration device for generating vibration, the vibration device configured to receive a soundwave signal and comprising: a lower body being open at a top thereof, and defining an accommodation space therein; a lower bracket being open at a top and a bottom thereof, and provided in the accommodation space of the lower body; a magnetic body fixedly provided on a bottom surface of the lower body to generate a magnetic force; a bobbin provided in the lower bracket to be located above the magnetic body; a voice coil provided on an outer circumference of the bobbin to interact with the magnetic body; a damper provided on an upper surface of the bobbin, coupled to an upper surface of an edge of the lower bracket, and vibrating by interaction between the magnetic body and the voice coil; a connection member (170, 170a) coupled at a lower end thereof to a central portion of the damper and a central portion on the upper surface of the bobbin; a vibration probe (190, 260, 262, 264, 266) for stimulating a human body, wherein the connection member (170, 170a) is coupled at an upper end thereof with the vibration probe (190, 260, 262, 264, 266), thus transmitting vibration from the damper to the vibration probe; an upper body covering the open top of the lower body, the connection member (170, 170a) being inserted into an insertion hole formed in a center on an upper surface thereof; and an upper bracket being open at a bottom thereof, and accommodated in an internal space of the upper body to be coupled with the lower bracket, the connection member (170, 170a) being inserted into an insertion hole formed in an upper surface thereof, wherein the damper comprises a plate provided in a shape of a plate and configured to vibrate and a plurality of dampers arranged along an edge of the plate to extend long in a shape of a radially curved band, with a coupling hole being formed in an end of each of the dampers to be used for screw-type fastening, wherein the dampers are fixedly coupled between edges of the upper and the lower bracket, wherein a plurality of first heat dissipation holes are formed in the upper surface of the upper body outside the insertion hole formed in the center of the upper surface of the upper body, wherein a plurality of second heat dissipation holes are formed in the upper surface of the upper bracket outside the insertion hole formed in the center of the upper surface of the upper bracket, wherein a plurality of third heat dissipation holes are formed in the plate outside a coupling hole formed in the center of the plate which coupling hole is coupled with the lower end of the connection member, and a plurality of fourth heat dissipation holes are formed in the upper surface of the bobbin outside a coupling hole formed in a center of the upper surface of the bobbin which coupling hole is coupled with the lower end of the connection member. a lower body being open at a top thereof, and defining an accommodation space therein;
