1. A vibration device for generating vibration using sound pressure, the vibration device 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 cone paper damper provided on an upper surface of the bobbin, coupled to an upper surface of an edge of the lower bracket, and vertically generating vibration by interaction between the magnetic body and the voice coil; and a connection member coupled at a lower end thereof to a central portion of the cone paper damper and a central portion on the upper surface of the bobbin, and coupled at an upper end thereof with a vibration probe for stimulating a human body, thus transmitting vibration from the cone paper damper to the vibration probe. |
