PURPOSE: A sound converter is provided to improve workability and productivity by easily positioning a vibration plate made of soft material on a right position of a frame. CONSTITUTION: A vibration plate assembly includes a central unit, a vibration plate with a side dome formed around the central unit, and a coil unit(50) mounted around the lower surface of the central unit. A magnetic circuit orthogonally interlinks the magnetic flux on one side of the coil unit part. A frame(20) comprises a first receiving unit receiving a magnetic circuit and a second receiving unit receiving the vibration plate assembly. A guide member positions the vibration plate assembly in the right position of the second receiving unit. A protector(70) protects the vibration plate on the upper side of the frame. The second receiving unit of the frame includes a vibration plate receiving unit corresponding to the receiving unit formed outside of the side dome of the vibration plate. |
