The present invention relates to a structure technique for assembling flat board type vibration plate speaker of television, especially a structure for assembling flat board type vibration plate speaker of television to inhibit the division vibration of the flat board type vibration plate and improve the timbre of the speaker through a plurality of assistant cones. It includes the following structures: a brim to moderate the impact by the vibration of the flat board type vibration plate with one end disposed on the back of the flat board type vibration plate; a gasket located on the other end of the above brim adjacent the flat board type vibration plate; a frame disposed on the back of the brim; a first assistant cone and the second assistant cone mounted on the speaker host in turn to inhibit the division vibration of the flat board type vibration plate between the brim of the two ends and the frames of the flat board type vibration plate. The division vibration of the flat board type vibration plate is inhibited through a plurality of assistant cones to embody the merit of the design of the flat board type vibration plate to reach the effect to improve the timbre of the speaker. |
