The present invention relates to a vibration plate made of magnesium or magnesium alloy which has light weight, excellent strength, and excellent conductivity. More particularly, a body, made of magnesium or magnesium alloy, is applied to make the thickness of the vibration plate be thin; an electrical signal, input to a suspension, is prevented from entering the body by an insulation member installed between the body, made of magnesium, and the suspension, made of a conductive metal; and high power and high quality of sound can be obtained by attaching multiple bobbins directly to the bottom of the body. The present invention relates to a magnesium vibration plate module and a rectangular speaker using the same. |
