Abstract
A sound vibration actuator includes: a casing having an internal space formed by an underside casing part, a side periphery casing part, and a top casing part; a coil part coupled to the top casing part in such a manner as to receive power from the outside; a magnet part disposed in the internal space of the casing and having a magnet and a weight; an elastic member whose one surface coupled to the magnet part; and a weight part coupled to the coil part. The sound vibration actuator can be varied in coupling ways of the components thereof to generate vibrations in a high frequency band as well as a low frequency band.
