PURPOSE: A speaker which evenly transfers the vibration of a vibration plate is provided to uniformly transfer the vibration of a vibration plate by attaching a vibration secondary member to the vibration plate. CONSTITUTION: One or more magnets(12a,12b) forms a magnetic field. One or more voice coils(14a,14b) forms a magnetic field by current to the outside. The voice coil exercises in one or more magnets through interaction with the formed magnetic field. A vibration plate(16) is vibrated by the exercise of one or more voice coils. The vibration plate generates sound through vibration. One or more vibration secondary members are attached to the vibration plate. The vibration secondary members(15a,15b) evenly transfer the vibration through the interaction of magnet and voice coil to the vibration plate. |
