FLAT VIBRATING PLATE AND PLANAR SPEAKER USING THE SAME

摘要

PURPOSE: A flat plate and a flat speaker using the same are provided to increase rigidity and elasticity by the formation of a flat vibration plate with insulating resin. CONSTITUTION: A flat speaker(1) comprises a fixed-shape frame(2), two yokes(3) installed in the frame, a magnet(4), an upper plate(5), two voice coils(6), and flat vibration plate(7). The flat vibration plate comprises a flat part(11), an edge part(15) installed along the edge of the flat plate, and multiple conductive suspensions(17). The flat plate is located on the center portion of the flat vibration plate. The flat plate is formed of the hard material. The edge part fixes the flat plate on the frame. The conductive suspension is installed between the flat plate and the frame.
